Effectiveness of pelvic floor muscle biofeedback electrical stimulation combined with pelvic floor muscle training for mild to moderate postpartum stress urinary incontinence / 中华围产医学杂志

Objective:To analyze the effects of pelvic floor muscle biofeedback electrical stimulation (PEMS) combined with pelvic floor muscle training (PFMT) and PFMT alone on mild to moderate stress urinary incontinence (SUI) after delivery.Methods:This retrospective study involved 1 087 postpartum women with mild or moderate SUI who were admitted to the Affiliated Hospital of Jining Medical University from January 2017 to January 2021. According to the treatment approaches, they were divided into two groups: the PMES+PFMT group ( n=504) and the PFMT group ( n=583). Chi-square test, independent sample t-test and rank sum test were used to compare the objective indicators (pelvic floor muscle strength test, vaginal dynamic pressure value test, 1-h pad test) and subjective indicators [incontinence impact questionnaire short form (IIQ-7), incontinence questionnaire-urinary incontinence short form (ICI-Q-SF), pelvic organ prolapse/urinary incontinence sexual function questionnaire (PISQ-12)] before, immediate and three months after treatment between the two groups. Results:There was no significant difference between the two groups in the values of vaginal dynamic pressure before treatment, 1-h pad test results and subjective indicators (all P>0.05). Comparison within groups: Indicators were improved in both groups immediate and three months after treatment compared with before treatment, including strength of type Ⅰ muscle [PMES+PFMT group: grade 4 and 5 (normal): 43.5% (219/504) and 42.1% (212/504) vs 1.2% (6/504), χ 2=864.27 and 861.46; PFMT group: grade 4 and 5:19.2% (112/583) and 20.1% (117/583) vs 1.5% (9/583), χ 2=1 148.26 and 1 038.29] and class Ⅱ muscle strength [PMES+PFMT group: 48.4% (244/504) and 50.8% (256/504) vs 4.8% (24/504), χ 2=862.96 and 819.24; PFMT group: 37.4% (218/583) and 38.9% (227/583) vs 5.0% (29/583), χ 2=1 029.47 and 998.54; all P < 0.05].Vaginal dynamic pressure increased [PMES+PFMT group: (89.3±5.4) and (82.2±4.6) vs (67.5±12.7) cmH 2O (1 cmH 2O=0.098 kPa), t=802.13 and 845.54; PFMT group:(80.2±4.3) and (78.6±4.5) vs (66.9±14.2) cmH 2O, t=288.37 and 244.94], and 1-hour urine leakage reduced [PMES+PFMT group: 2.0 g (2.0-3.0 g) and 2.0 g (1.0-3.0 g) vs 6.0 g (5.0-6.0 g), Z=825.39 and 802.13; PFMT group: 4.0 g (3.0-5.0 g) and 3.0 g (3.0-4.0 g) vs 5.0 g (4.0-6.0 g), Z=836.34 and 811.25], and IIQ-7 scores [PMES+PFMT group: scores of 3 (2-4) and 4 (3-4) vs 8 (7-9), Z=959.52 and 825.87; PFMT group: 5 (4-5) and 5 (4-6) vs 8 (7-10), Z=916.27 and 903.18], and ICI-Q-SF score [PMES+PFMT group: 3.5 (3-4) and 4 (3-5) vs 10 (9-12), Z=952.79 and 924.94; PFMT group: 6 (4-7) and 6 (5-7) vs 11 (10-12), Z=1 049.89 and 998.15], and PISQ-12 score [PMES+PFMT group: 10 (7-12) and 9 (7-12) vs 21 (17-24), Z=862.55 and 887.17; PFMT group: 13 (11-16) and 14 (12-16) vs 22 (18-25), Z=1 026.73 and 934.86, all P<0.05) decreased. Compared with the PFMT group, the above indexes were all better in the PMES+PFMT group (all P<0.05). Conclusion:PFMT alone or in combination with PMES can both enhance pelvic floor muscle strength, increase vaginal dynamic pressure, alleviate urine leakage and improve the quality of life and PMES+PFMT is better and more effective.

Prevalence and risk factors of overactive bladder in elderly women with stress urinary incontinence / 中华老年医学杂志

Objective:To explore the risk factors of overactive bladder(OAB)syndrome in older women with stress urinary incontinence(SUI).Methods:In this cross-sectional study, 157 elderly women with SUI, aged 60-88(65.6±5.4)years, were recruited from Qingshan District Maternal and Child Health Hospital and areas serviced by Fozuling Community Service Center in Wuhan between October to November 2020.Data collection included a questionnaire covering general information, dietary habits, childbirth history, medical history, the urogenital distress inventory(UDI-6)and the overactive bladder symptom score(OABSS), and physical examinations on curvature of the spine, pelvic floor muscle strength and pelvic floor ultrasound imaging.Results:A total of 157 elderly women with SUI were included in the study and the prevalence of OAB was 17.2%(27 cases). The prevalence of OAB was 17.6%(25 cases)among 142 patients with mild SUI and 13.3%(2 cases)among 15 patients with moderate or severe SUI, but SUI severity was not correlated with the prevalence of OAB( χ2=0.003, P>0.05). The UDI-6 score was 2.39±2.04 and the OABSS score was 3.70±2.48, with a positive correlation between OABSS and UDI-6( r=0.254, P<0.01), suggesting that OAB had a negative effect on the quality of life of patients with SUI.Multivariate Logistic regression analysis on factors with P<0.3 in the univariate analysis showed that number of pregnancies( P<0.01), anterior vaginal wall prolapse( P<0.05), and abnormal inclination of the pelvis( P=0.05)were associated with the prevalence of OAB.Regarding the number of pregnancies, the risk of OAB increased with 2-3 pregnancies( OR=1.46, 95% CI: 0.25-8.56)and with 3 pregnancies or more( OR=4.29, 95% CI: 0.79-23.18), compared with the prevalence at no more than 1 pregnancy.Compared with patients without anterior vaginal wall prolapse, Ⅰ-Ⅱ degree prolapse increased the risk of OAB( OR=4.21, 95% CI: 1.40-12.63), and third-degree prolapse further increased the risk( OR=11.48, 95% CI: 1.37-96.17). Compared with patients with normal inclination of the pelvis, anterior or posterior pelvis inclination promoted the occurrence of OAB( OR=3.46, 95% CI: 1.23-9.73; OR=2.62, 95% CI: 0.54-12.71). Conclusions:OAB has a negative impact on the quality of life of elderly women with SUI.Pregnancy, anterior vaginal prolapse and abnormal inclination of the pelvis promote the occurrence of OAB.

A novel nomogram and a simple scoring system for urinary leakage after percutaneous nephrolithotomy

ABSTRACT Introduction: The present study aimed to investigate the factors of prolonged urinary leakage (PUL) after percutaneous nephrolithotomy (PCNL) and develop a new and simple scoring system to predict it. Patients and Methods: We retrospectively reviewed patients with renal stones who underwent PCNL at the University of Health Sciences Izmir Bozyaka Training and Research Hospital between April 2011 and January 2020. The patients were divided into two groups according to the presence of PUL, and their preoperative and perioperative data were compared. A multivariate regression analysis was applied to examine the relationship between perioperative descriptors and PUL, and a nomogram was developed using significant predictors. Then, the individual components of the nomogram were assigned points to form a scoring system. Results: There were 92 and 840 patients in the groups with and without PUL, respectively. The results of the univariate logistic regression analysis showed that hydronephrosis grade, parenchymal thickness, duration of nephroscopy, and duration of nephrostomy catheter were significantly associated with PUL. Subsequently, a multivariate regression analysis was carried out with these four factors as possible independent risk factors of PUL after PCNL. Based on the results of this analysis, a nomogram prediction model was developed with an area under the curve value of 0.811, which was consequently used to develop a new simple score system consisting of three characteristics: parenchymal thickness (1-5 points), duration of nephroscopy (1-3 points), and hydronephrosis grade (1-3 points). Conclusion: A novel scoring system is a useful tool for predicting PUL in patients who have undergone percutaneous nephrolithotomy.

Risk factors for stress urinary incontinence during pregnancy and postpartum period / 中华围产医学杂志

Stress urinary incontinence (SUI) is closely related to pregnancy and delivery. With the implementation of the three-child policy and the increasing number of pregnant women at advanced age or with obesity, the prevalence of SUI during pregnancy and the postpartum period is increasing gradually. Risk factors of SUI that are associated with pregnancy and childbirth include delivery mode, advanced maternal age, overweight/obesity, macrosomia, prolonged second stage of labor, epidural anesthesia, and breastfeeding. Identification of such risk factors is crucial for early intervention for high-risk patients, which would be conducive to reducing the risk of long-term SUI.

Evaluation of urethral morphology and function in female patients with stress urinary incontinence by static and dynamic pelvic floor MRI and diffusion tensor imaging / 中华放射学杂志

Objective:To explore the value of the static and dynamic pelvic floor MRI and diffusion tensor imaging (DTI) in evaluating the morphology and function of urethra in patients with stress urinary incontinence (SUI).Methods:From July 2020 to February 2021, a total of 28 patients with SUI and 45 age-matched healthy controls were prospectively collected at the First Affiliated Hospital of Zhengzhou University. The static and dynamic pelvic floor MRI and DTI were performed for all subjects. The thickness of internal and external sphincter of middle urethra were measured on static MRI images. The functional urethral length (FUL) was measured both on static and maximal strain phase of dynamic MRI images, then the difference of FUL was calculated. The presence of bladder neck funneling and urethra opening were observed on static and dynamic MRI. The muscle fiber bundle image of urethral sphincter complex was obtained by post-processing of DTI original images. The anisotropy fraction (FA), apparent diffusion coefficient (ADC) and three eigenvalues (λ1, λ2, λ3) of annular sphincter and central longitudinal muscle in middle urethra were measured. The independent sample t test and chi-square test were used to analyse the difference of measured parameters in MRI, parameters of DTI and imaging signs between the two groups. Results:Compared with healthy controls, the SUI patients showed that the thickness of external sphincter in middle urethral and FUL in static status and maximal strain phase were significantly decreased ( t=-3.95, -5.72, -8.41, all P<0.001), the difference of FUL between static status and maximal strain phase was significantly increased ( t=4.41, P<0.001). The positive rate of bladder neck funneling in static status and maximal strain phase, urethral opening in maximal strain phase of SUI group increased significantly (χ2=23.09 , 22.25, 26.59, all P<0.001). In SUI group, the FA value of middle urethral annular sphincter decreased significantly ( t=-3.48, P=0.001), while the ADC, λ2 and λ3 values increased significantly ( t=3.19, 2.15 , 2.06, and P=0.002, 0.038 , 0.046, respectively). There was no significant difference in DTI parameters of middle urethral longitudinal muscle between the two groups (all P>0.05). Conclusions:Static and dynamic MRI and DTI techniques can objectively evaluate the changes of urethral morphology and function of SUI patients. The thinning of the external sphincter in the middle urethra, shortening of the FUL and the destruction of the microstructure of the annular sphincter fiber bundle were the main alterations of SUI patients.

Application value of pelvic floor ultrasound in screening early postpartum stress urinary incontinence / 中国基层医药

Objective:To investigate the application value of pelvic floor ultrasound in screening early postpartum stress urinary incontinence (SUI).Methods:A total of 220 postpartum women, who were admitted by the Department of Gynecology and Obstetrics of The People's Hospital of Hechi from January 2018 to June 2019, were selected for this study. These women were divided into SUI ( n = 52) and no SUI ( n = 168) groups according to whether SUI occurred within 42 days after delivery. Pelvic floor ultrasound parameters and clinical data were compared between the two groups. The effects of each ultrasound parameter on postpartum SUI were assessed. The receiver operating characteristic (ROC) curve was plotted for each parameter. The area under the ROC was calculated. The risk factors for postpartum SUI were investigated using the logistic regression analysis. Results:The number of deliveries (≥ 2 times), the proportion of women subjected to vaginal delivery, and neonatal weight in the SUI group were significantly higher than those in the no SUI group [ χ2 = 4.13, 3.30, t = 4.43, all P < 0.05]. There were significant differences in the bladder neck position and levator hiatus area in the resting state between the two groups ( t = 2.29, 3.09, both P < 0.05). There were significant differences in the bladder neck position, levator hiatus area, urethral rotation angle, and bladder neck mobility during the Valsalva movement between the two groups ( t = 13.14, 4.27, 15.64, 8.54, all P < 0.05). The areas under the ROC of bladder neck position and levator hiatus area in the resting state and the areas under the ROC of bladder neck position, levator hiatus area, urethral rotation angle, and bladder neck mobility during the Valsalva movement were 0.707, 0.725, 0.730, 0.771, 0.813, and 0.836, respectively. The area under the ROC of parameters used in combination was 0.849. Logistic regression analysis results revealed that the number of deliveries (≥ 2 times), bladder neck position (> 27.286 mm) and levator ani hiatus area in resting state (> 16.663 cm 2), and bladder neck position (< -2.774 mm), levator hiatus area (> 21.915 cm 2), urethral rotation angle (> 80.445°), and bladder neck mobility (> 30.501°) during the Valsalva movement were the risk factors for postpartum SUI. Conclusion:Combined use of pelvic floor ultrasound parameters is valuable for the diagnosis of postpartum SUI. Abnormal changes in the bladder neck position, levator ani hiatus area, urethral rotation angle, and bladder neck mobility are closely related to the occurrence of postpartum SUI. Therefore, combined use of pelvic floor ultrasound parameters can be preferred to screen early postpartum SUI.

Analysis of the long-term outcomes of different secondary surgeries for recurrent stress urinary incontinence after Burch colposuspension / 中华妇产科杂志

Objective:To analyze the long-term outcomes of different secondary surgeries in women with recurrent stress urinary incontinence (SUI) after Burch colposuspension.Methods:Between February 2004 to February 2010, five women with recurrent SUI after Burch colposuspension in Peking Union Medical College Hospital were retrospectively followed up, and the long-term outcomes of secondary surgeries were analyzed. Subjective cures of Burch colposuspension and secondary surgeries were assessed by patients′ self-reported incontinence symptoms and patient global impression of improvement questionnaire; objective cure, improvement or failure were determined by 1-hour pad test.Results:Three women underwent tension-free vaginal tape-retropubic (TVT) as the secondary surgery, one underwent tension-free vaginal tape-obturator (TVT-O), and one underwent single-incision tension-free vaginal tape-Secur (TVT-Secur). The follow-up period of five women was (14.6±2.4) years (range: 10.8 to 16.9 years). Three women undergoing TVT secondary surgery were subjectively cured; while the other two women undergoing TVT-O or TVT-Secur were not subjectively cured, but the woman undergoing TVT-O was objectively improved.Conclusions:It is feasible for women with recurrent SUI after Burch colposuspension to receive the secondary surgery. Our limited data suggests that TVT could be considered.

Long-term efficacy of AdVance obturator sling and artificial urethral sphincter in treatment of male stress urinary incontinence / 中华泌尿外科杂志

Objective:To evaluate the long-term efficacy of AdVance sling bulbar urethral suspension and artificial urethral sphincter (AUS) implantation in the treatment of moderate to severe male stress urinary incontinence.Methods:The clinical data of 12 male patients with urinary incontinence who underwent surgical treatment in Peking University People's Hospital from June 2011 to June 2017 were retrospectively analyzed. The median age was 75(64-80) years. There were 9 cases after radical prostatectomy and 3 cases after transurethral prostatectomy. Patients had a median history of urinary incontinence of 3(1-9) years, and needed an average of 8(5-10) pads per day. Among them, 5 patients had moderate urinary incontinence and 7 patients had severe urinary incontinence. All patients underwent urinary incontinence surgery for the first time. Among the 12 patients, 6 received AdVance sling ball urethral suspension (AdVance group), and 6 received AUS implantation (AUS group). The median age of the AdVance group was 72 (64-73) years. The median number of pads used daily was 6 (5-8) tablets. Urinary incontinence Quality of Life questionnaire (I-QOL) score was (15.0±5.4). Five patients had moderate urinary incontinence and one patient had severe urinary incontinence. In the AUS group, the median age was 78(76-80) years old, the median daily pad use was 8(6-10) tablets, and the I-QOL score was (16.7±5.1), all of which were severe urinary incontinence. The daily pad usage, I-QOL and postoperative complications were recorded at 1 and 5 years after operation.Results:All patients completed the operation successfully. The postoperative follow-up was 5-7 years (mean 5.5 years). In AdVance group, 1 patient with severe urinary incontinence had no significant improvement in postoperative symptoms at 1 year after operation. The other 5 patients showed significant improvement in urinary incontinence symptoms. In the AdVance group, the median number of pads used per day was 2.5 (1-10), and the I-QOL score was (75.0±28.1), which were all significantly improved compared with that before operation ( P<0.05). The median number of pads used per day in the AdVance group 5 years after operation was 2.5(1-10), and the I-QOL score was (78.3±29.3), which were significantly improved compared with those before operation (all P<0.01). In the AUS group, no pad was needed at 1 year after operation, which was significantly improved compared with that before operation ( P<0.01). Urethral erosion occurred in 2 cases 3 years after operation, and the AUS was removed. Urinary incontinence recurred and returned to the preoperative state without reoperation. The other 4 cases did not need to use the pad 5 years after operation. In AdVance group, 3 patients had perineal pain within 3 months after operation, which was related to activity and relieved spontaneously. No wound infection, urethral erosion and other complications occurred. Urethral erosion occurred in 3 cases in AUS group. Conclusions:AdVance sling ball urethral suspension is effective for patients with moderate stress urinary incontinence and has fewer complications. AUS implantation is effective for patients with severe male stress urinary incontinence. However, the long-term complications of this operation may affect the postoperative efficacy.

Clinical observation of adjusting middle urethral sling tension through anatomic position during RMUS / 中华泌尿外科杂志

Objective:To investigate the safety and effectiveness of tension adjustment technique using anatomical landmarks during retropubic midurethral synthetic sling.Methods:The data of 36 consecutive female patients with urinary incontinence, who had underwent retropubic midurethral synthetic sling procedure from January to August 2019 were analyzed retrospectively. The mean age was (60.83±7.93) years old and the body mass index was (24.43±2.44) kg/m 2. Among the recruited subjects, 36 had positive stress test and Marshall-Marchetti test. 20 (55.6%) were pure stress urinary incontinence, and 16 (44.4%) were mixed urinary incontinence. The severity of incontinence was classified into mild (5 cases, 13.9%), moderate (14 cases, 38.9%), severe (13 cases, 36.1%) and very severe (4 cases, 11.1%) using one-hour pad tests. Urodynamics were performed in 17 cases, with 5 (29.4%) presented detrusor overactivity, 3 (17.7%) possessed intrinsic sphincter deficiency. For each case, the tension of the sling was adjusted based on the anatomical landmarks, i. e. using an angled clamp attached closely to the pubic symphysis ventrally and the tip parallel to the edge of hymen dorsally. All patients were catheter-free right after the procedure. The subjective and objective effectiveness, and safety (the rate of urinary retension after surgery and postvoid residual volume 3 months later) were evaluated.The subjective cure rate was was defined as complete leakage free or very mild leakage during excessive bladder filling and fierce cough. The subjective effectiveness was defined as over 50% improvement of the leakage symptom. The objective cure rate was defined as a negative stress test. Results:For all 36 patients, the median hospital stays was 8 (5-95)h. No bladder perforation or transfusion cases. All patients were catheter-free right after the procedure, with no incidence of urinary retention. 27 patients completed a 3-month follow-up, with 22 had post-void residual data, 23 had subjective effectiveness data and 23 had objective effectiveness data. The median post-void residual was 7.5 (5-64) ml, subjective cure rate was 91.3% (21/23), and objective cure rate was 95.7% (22/23). 8.7% (2/23) reported difficult urination alleviated without the necessity of clinical interference. No urethra erosion or vagina extrusion was found. At 2-year follow-up, 34 patients completed assessment by phone. The subjective cure rate was 91.2% (31/34), with only 2.9% (1/34) reported difficult urination. Besides, at 3-month follow-up, there was no difference regarding the subjective cure rate [100.0%(12/12) vs. 81.8%(9/11)]or objective cure rate [91.7%(11/12) vs. 100.0%(11/11)] between patients with stress and mixed incontinence. No difference was noted among patients with mild, moderate, severe and very severe leakage[75.0% (3/4) vs. 100.0%(6/6) vs. 90.0%(9/10) vs. 100.0%(3/3)]. Of the 12 cases with urodynamic records, the presence of detrusor overactivity [66.7%(2/3) vs. 88.9%(8/9)] or intrinsic sphincter deficiency [0(0/1) vs. 90.9%(10/11)] did not significantly affected the cure rate of the procedure. At 2-year follow-up, there was no difference regarding the subjective cure rate between patients with stress and mixed incontinence [94.7%(18/19) vs. 86.7%(13/15)]. No difference was also noted among patients with mild, moderate, severe and very severe leakage[80.0%(4/5) vs. 100.0%(13/13) vs. 83.3%(10/12) vs. 100.0%(4/4)]. Of the 16 cases with urodynamic records, the presence of detrusor overactivity [60.0%(3/5) vs. 90.9%(10/11)]or intrinsic sphincter deficiency [66.7%(2/3) vs. 84.6%(11/13)]did not significantly affected the cure rate of the procedure.Conclusions:Tension adjustment using anatomic landmarks during sling procedure is safe and feasible for urinary incontinence, with minimum complications and residual volume, and high subjective/objective cure rate.

Long term follow up outcome of artificial urinary sphincter implantation to treat stress urinary incontinence / 中华泌尿外科杂志

Objective:To investigate the long term outcome of artificial urinary sphincter implantation for patients with stress urinary incontinence.Methods:The data of 46 patients who underwent artificial urethral sphincter implantation in China Rehabilitation Research Center from April 2002 to April 2022 were retrospectively analyzed.The patients’ age ranged from 19-80 years old (median 45.6 years). There were 45 males and 1 female. The history of illness was 8 months to 33 years. The patients category were urethral injuries associated urinary incontinence ( n=24), neurogenic urinary incontinence ( n=9) and post-prostatectomy incontinence ( n=13). Preoperative daily pad usage was 3.5±1.0. The impact of incontinence on the quality of life (QOL)measured by the visual analogue scale (VAS)was 7.1±1.2. All 46 patients underwent artificial urethral sphincter implantation, of which 20 patients were treated with anticholinergic drugs (5 cases) or urinary tract related surgery (urethral stenosis incision in 2 cases, sphincterectomy in 3 cases, urethral dilation in 5 cases, urethral calculus lithotripsy in 1 case, and augmentation cystoplasty in 4 cases) before artificial urethral sphincter implantation. Of the 45 male patients, 25 patients had the transperineal approach and 20 had the trans-scrotal approach. The female case had a trans-retropubic approach. Different cuffs size was used based on individual circumference of bulbar urethra (45 male cases: 4.5cm in 16 cases, 4.0cm in 29 cases; one female case: 8.0cm). Long-term surgical efficacy was evaluated. Assessments included postoperative urinary continence (socially continent: one pad per day or less; complete dry: wearing no pads), artificial urinary sphincter status and complications. The influences of patients of different etiologies, surgical approaches and cuff size on surgical results were compared. Results:The mean follow-up time was 7.1 years ranged from 6 months to 19 years. At the latest visit, 32 patients (69.6%) maintained the primary functional artificial urinary sphincter. Three patients (6.5%) had artificial urinary sphincter revisions and maintained continence with the new device. 11 patients (23.9%) removed the artificial urinary sphincter because of post-complications. Thirty-five patients were socially continent, of which 16 patients were totally dry, leading to the overall social continent rate as 76.1%(35/46). There was a significant reduction in pad usage to 1.2±0.6 diapers per day ( P<0.001). The impact of incontinence on the QOL measured by the VAS dropped to 2.6±1.9 ( P<0.001). The complication rate was 32.6%(15/46), including infections ( n=4), erosions ( n=5), mechanical failure ( n=3), dysurie ( n=2) and urethral atrophy ( n=1). There were no significant differences in social continent rate between patients with different etiologies[75.0%(18/24)vs. 66.7%(6/9) vs. 84.6%(11/13)], perioperative complications [37.5%(9/24)vs. 33.3%(3/9) vs. 23.1%(3/13)] and device re-intervention rate[37.5%(9/24) vs. 33.3%(3/9)vs. 15.4%(2/13)]. There were no statistically significant differences in postoperative complete dry rate [32%(8/25)vs. 40%(8/20), P=0.76] and postoperative device failure free rate [60%(15/25)vs. 80%(16/20), P=0.20] between trans-perineal group and trans-scrotal group. There was no statistically significant difference in postoperative social continent rate between 4.5cm cuff and 4.0 cuff[75%(12/16) vs. 65.5%(19/29), P=0.74]. Conclusions:Artificial urethral sphincter implantation is an effective treatment for stress urinary incontinence due to intrinsic sphincter deficiency. There was no difference in the continent rate and complication rate between patients of different etiologies, different surgical approaches and cuff size selection.

Objective:To analyze the clinical efficacy and safety of surgical excision of slings in the treatment of voiding dysfunction after the midurethral sling(MUS)procedure.Methods:A retrospective analysis was conducted on postoperative patients with voiding dysfunction after MUS from January 2016 to June 2021.The ages of the patients ranged from 47 to 73 years, with an average of(61.3±8.2)years.The patients were followed up for preoperative and postoperative urinary flow rates and PVR, and results from the ICI-Q-SF were collected from patients for statistical analysis.Results:The shortest time from the first sling procedure to the occurrence of voiding dysfunction was 2 months and the longest was 7 months, with an average of(3.8±1.8)months.The earliest surgical excision was performed 5 months after MUS and the latest was done 24 months after MUS, with an average of(12.3±6.6)months.Among the 12 patients, symptoms of 11 patients after surgical excision of slings were significantly improved, compared with pre-surgery data.The urinary flow rate was 9.3(3.7, 13.2)ml/s before surgery and 21.5(15.7, 34.2)ml/s after surgery, P=0.004; The residual urine volume before surgery: 315(200, 377)ml, after surgery: 0(0, 80)points, P<0.001, both with statistical significance; preoperative ICI-Q-SF: 0(0, 5)points, postoperative: 4(0, 8)points, There was no significant difference between before and after operation( P=0.348). Conclusions:Surgical excision of slings is safe and effective in the treatment of voiding dysfunction after MUS.

Establishment and validation of nomogram for postpartum stress urinary incontinence / 中华泌尿外科杂志

Objective:To analyze the predictive factors of postpartum SUI, and establish and validate nomogram model.Methods:A total of 272 patient from Affiliated Jinhua Hospital, Zhejiang University School of Medicine were reviewed, and the general clinical data and ultrasound parameters were analyzed. The median age (range) was 32 (28-38) years. Vaginal delivery was recorded in 191(70.0%), while cesarean section was performed in 81(30.0%) cases. The average body mass index (BMI) was (23.0±2.9) kg/m 2. The median bladder neck mobility was 2.5cm and rate of bladder neck funnel was 25%. Patients were divided into two groups: Group SUI(n=98) and Group NSUI (without SUI, n=174). The independent predicting SUI were analyzed by univariate and multivariate logistic regression analysis. Two predictive models were constructed with the important general clinical data and ultrasound parameters, then receiver operating characteristic (ROC) curve analyses were conducted to evaluate the predictive power of two models. At last, the nomogram was established for the better model. Results:The results of multivariate analysis showed that age( OR=1.08, P=0.011), delivery method( OR=9.26, P<0.01), body mass index( OR=1.15, P=0.023), bladder neck distance ( OR=1.73, P=0.047) and bladder neck funneling( OR=18.44, P<0.01) were independent predictors for SUI. Two predictive models were used with independent predictors of SUI. The area under the receiver operating characteristic(ROC)curve of validation group was 0.88. The area under the ROC curve of general clinic factors was 0.77. The difference between the two model and other indicators was statistically significant( P<0.001). The nomogram model was well calibrated, with the mean absolute error of 1.9%. Conclusions:Age, delivery method, BMI, bladder neck mobility and bladder neck funneling were independent predictors for SUI. The nomogram model for predicting SUI has a good statistical significance.

Clinical assessment of tension-free vaginal tape surgery for the treatment of recurrent stress urinary incontinence in women / 中华老年医学杂志

Objective:To analyze the clinical efficacy and safety of the retropubic tension-free vaginal tape(TVT)procedure for postoperative recurrent urinary incontinence in women.Methods:Retrospective analysis was conducted on twenty-two patients who had developed recurrent urinary incontinence after mid-urethral sling(MUS)surgery and received the retropubic TVT procedure via the middle urethra from January 2016 to June 2020.Patients were between 44 and 74 years old, with a mean age of 61.2±10.2.They were initially treated with the TVT and inside-out trans-obturator(TVT-O)procedures and were followed up by using the International Consultation on Incontinence Questionnaire-Short Form(ICI-Q-SF). Then statistical analysis was performed.Results:No bladder or urethral puncture wounds were observed in the 22 patients during cystoscopy.No pain, sling, vaginal or urethral erosion, or postoperative sling infection was found in any of the patients during a long-term follow-up.Considerable improvement was achieved in frequency of leakage[pre-operation: 4(4, 5) vs.post-operation: 1(1, 2), P<0.001], urine leakage volume[pre-operation: 6(4, 6)ml vs.post-operation: 2(2, 2)ml, P<0.001], impact on quality of life[pre-operation: 10(8, 10) vs. post-operation: 2(1, 3), P<0.001]and ICI-Q-SF[pre-operation: 20(18, 21) vs. post-operation: 5(3, 7), P<0.001]after TVT. Conclusions:TVT is safe and effective for the treatment of recurrent urinary incontinence after MUS surgery.

Clinical significance of three-dimensional pelvic floor ultrasound parameters in patients with stress urinary incontinence / 中国医师杂志

Objective:To explore the clinical significance of three-dimensional pelvic ultrasound parameters in patients with stress urinary incontinence (SUI).Methods:A total of 100 patients with SUI in the First Hospital Affiliated to Hunan Traditional Chinese Medical College from January 2018 to April 2020 were prospectively selected as the observation group, and 100 women who had undergone birth without SUI and other urinary system diseases who came for physical examination during the same period were selected as the control group. Comparing the three-dimensional pelvic floor ultrasound parameters of resting state and Valsalva action in the patients with different degrees of illness, the patients with different efficacy of the two groups and the observation group. Analyzing the correlation between three-dimensional pelvic floor ultrasound parameters and the severity and efficacy of SUI patients.Results:⑴ The posterior urethrovesical angel at rest and after Valsalva action, the pelvic diaphragmatic hiatus area after Valsalva action in the observation group were larger than those in the control group, and the puborectalis muscle thickness at rest and after Valsalva action was smaller than that of the control group, with statistically significant difference( P<0.05); ⑵ The posterior urethrovesical angel at rest and after Valsalva action, the pelvic diaphragmatic hiatus area at rest, and the puborectalis muscle thickness at rest and after Valsalva action were related to SUI ( P<0.05); ⑶ Comparison of patients with stress urinary incontinence of different severity: the posterior urethrovesical angel at rest and after Valsalva action, the pelvic diaphragmatic hiatus area after Valsalva action: mild<moderate<severe; the puborectalis muscle thickness at rest and after Valsalva action: mild>moderate>severe; ⑷ After treatment, the posterior urethrovesical angel and pelvic diaphragmatic hiatus area of patients with poor curative effect at rest and after Valsalva action were larger than those of patients with good curative effect, and the puborectalis muscle thickness of patients with poor curative effect at rest and after Valsalva action was smaller than that of patients with good curative effect, with statistically significant difference ( P<0.05); ⑸ The posterior urethrovesical angel at rest and after Valsalva action, the pelvic diaphragmatic hiatus area after Valsalva action were positively correlated with the degree of disease and clinical efficacy, while the puborectalis muscle thickness was negatively correlated with the degree of disease and clinical efficacy at rest and after Valsalva action ( P<0.05). Conclusions:Three-dimensional pelvic floor ultrasound examination can effectively reflect the changes in pelvic floor structure of SUI patients under different action states, and provides important anatomical and functional basis for the judgment of SUI disease degree and the evaluation of curative effect.

The effects of menopause on the quality of life and longterm outcomes of transobturator tape treatment in women with stres urinary incontinence

ABSTRACT Purpose: We aimed to investigate the effects of menopause on long-term outcomes of transobturator tape (TOT) surgery. Materials and Methods: Patients who underwent TOT surgery were evaluated under two groups as postmenopausal and premenopausal. The International Consultation on Incontinence short-form questionnaire (ICIQ-SF), Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory-Short Form (UDI-6) questionnaires were completed by the patients at the 1st and 5th-year follow-up sessions. Patients with a postoperative UDI-6 and IIQ-7 score of <10 were considered as cured, those with lower postoperative scores compared to the preoperative period were regarded as improved, and the cases that had higher postoperative scores than preoperative values were interpreted as TOT failure. The TOT success rates were compared between the results obtained from UDI-6 and IIQ-7. Results: A total of 109 patients were included in the study (53 postmenopausal and 56 premenopausal). We contacted with 90 (48 premenopausal and 42 postmenopausal) women at 1st year control and 80 (44 premenopausal and 36 postmenopausal) women at 5th year control. There was a significant improvement in all of three questionnaires between the preoperative and post-operative 1st year control (ICIQ-SF: 15.5±2.5 vs. 1.8±4.3, p <0.001; IIQ-7: 68.9±9.8 vs. 2.75±15.2, p <0.001; UDI-6: 27.1±11.1 vs. 6.0±14.6, p <0.001) and the preoperative and post-operative 5th year control (ICIQ-SF: 15.5±2.5 vs. 3.1±5.3, p <0.001; IIQ-7: 68.9±9.8 vs. 9.6±26.7, p <0.001; UDI-6: 27.1±11.1 vs. 5.1±10.0, p <0.001). When we compared the premenopausal and postmenopausal patients in terms of recurrent urinary tract infection (UTI); 5 (12%) patients had recurrent UTI in postmenopausal group but no patients had recurrent UTI in premenopausal group at 1st year follow-up (p=0.039) and similarly the same 5 (13.9%) patients in follow-up had recurrent UTI in postmenopausal group but no patients had recurrent UTI in premenopausal group at 5th year follow-up (p=0.045). There were no significant differences between the premenopausal and postmenopausal patients in terms of TOT success rates at 1st and 5th year control, evaluated with UDI-6 (1st year: p=0.198 and 5th year: p=0.687) and IIQ-7 (1st year: p=0.489 and 5th year: p=0.608) questionnaires. Conclusions: Transobturator tape surgery is an effective and reliable method according to the long-term outcomes reported in this paper. In the current study, we determined that the TOT success rates were not affected by the presence of menopause.

The impact of perioperative complications on favorable outcomes after artificial urinary sphincter implantation for post-prostatectomy incontinence

ABSTRACT Objective To investigate the effect of perioperative complications involving artificial urinary sphincter (AUS) implantation on rates of explantation and continence as well as health-related quality of life (HRQOL). Materials and methods Inclusion criteria encompassed non-neurogenic, moderate-to-severe stress urinary incontinence (SUI) post radical prostatectomy and primary implantation of an AUS performed by a high-volume surgeon (>100 previous implantations). Reporting complications followed the validated Clavien-Dindo scale and Martin criteria. HRQOL was assessed by the validated IQOL score, continence by the validated ICIQ-SF score. Statistical analysis included Chi (2) test, Mann-Whitney-U test, and multivariate regression models (p <0.05). Results 105 patients from 5 centers met the inclusion criteria. After a median follow-up of 38 months, explantation rates were 27.6% with a continence rate of 48.4%. In the age-adjusted multivariate analysis, perioperative urinary tract infection was confirmed as an independent predictor of postoperative explantation rates [OR 24.28, 95% CI 2.81-209.77, p=0.004). Salvage implantation (OR 0.114, 95% CI 0.02-0.67, p=0.016) and non-prostatectomy related incontinence (OR 0.104, 95% CI 0.02-0.74, p=0.023) were independent predictors for worse continence outcomes. Low visual analogue scale scores (OR 9.999, 95% CI 1,42-70.25, p=0.021) and ICIQ-SF scores, respectively (OR 0.674, 95% CI 0.51-0.88, p=0.004) were independent predictors for increased HRQOL outcomes. Perioperative complications did not significantly impact on continence and HRQOL outcomes. Conclusion Findings show postoperative infections adversely affect device survival after AUS implantation. However, if explantation can be avoided, the comparative long-term functional results and HRQOL outcomes are similar between patients with or without perioperative complications.

Cambios urodinámicos y en el punto Aa del sistema POP-Q, posterior a la colocación de cinta mediouretral / Urodynamic changes and at point Aa of POP-Q system, after midurethral sling placement

Resumen OBJETIVO: Determinar los cambios en el punto Aa del sistema POP-Q y en la prueba del Q-tip para hipermovilidad uretral y en los parámetros urodinámicos encontrados antes y 1 año después de la colocación de una cinta mediouretral. MATERIALES Y MÉTODOS: Estudio retrospectivo efectuado en pacientes a quienes se colocó una cinta mediouretral mediante acceso transobturador y retropúbico, por diagnóstico de incontinencia urinaria de esfuerzo, incontinencia urinaria mixta, incontinencia dual o con índice de riesgo de incontinencia urinaria de novo, posterior a cirugía de prolapso (R-CALC) mayor de 30%. RESULTADOS: Se estudiaron 200 pacientes de 51.59 ± 10.13 años de edad promedio. Conforme al grado de prolapso de órganos pélvicos, el estadio II tuvo una frecuencia de 57.5% (n = 115), el grado III de 21.5% (n = 43). En los hallazgos de la exploración física, previa a la cirugía, se encontró que 69% (n = 138) de las pacientes tuvieron una prueba de Q tip con hipermovilidad uretral (más de 30°). Al comparar el porcentaje de pacientes con hipermovilidad uretral posterior a 1 año de la cirugía, se observó disminución en las pacientes con hipermovilidad (p = 0.0001). La cuantificación del punto Aa en la escala del sistema POP-Q se encontró durante la exploración preoperatoria a 0.1 ± 1.17 cm respecto del himen y al año del procedimiento quirúrgico a -1.54 ± 1.18 cm, con p = 0.0001. CONCLUSIÓN: En todas las pacientes se demostró la disminución significativa del punto Aa en la revaloración del POP-Q de un estadio II a I posterior a la colocación de una cinta mediouretral; además de la disminución en el ángulo de movilidad uretral. No se observaron modificaciones significativas en los parámetros urodinámicos evaluados.

Abstract OBJECTIVE: To determine the changes in point Aa of the POP-Q system and in the Q-tip test for urethral hypermobility as well as in the urodynamic parameters found before and 1 year after mediurethral sling placement. MATERIALS AND METHODS: Retrospective study carried out in patients who were placed with a mediourethral tape by transobturator and retropubic access, by diagnosis of stress urinary incontinence, mixed urinary incontinence, dual incontinence or with risk index of de novo urinary incontinence after surgery. Prolapse (R-CALC) greater than 30%. RESULTS: 200 patients of 51.59 ± 10.13 years of average age were studied. According to the degree of pelvic organ prolapse, stage II had a frequency of 57.5% (n = 115), grade III with 21.5% (n = 43). In the physical examination findings, prior to surgery, it was found that 69% (n = 138) of the patients had a Q tip test with urethral hypermobility (more than 30°). When comparing the percentage of patients with urethral hypermobility after 1 year of surgery, a decrease was observed in patients with hypermobility (p = 0.0001). The quantification of point Aa on the scale of the POP-Q system was found during the preoperative examination at 0.1 ± 1.17 cm with respect to the hymen and one year after the surgical procedure at -1.54 ± 1.18 cm, with p = 0.0001. CONCLUSION: The significant decrease in point Aa in the reassessment of POP-Q from stage II to I after the placement of a mediourethral tape in all patients was demonstrated, in addition to the decrease in the angle of urethral mobility. No significant changes were observed in the urodynamic parameters evaluated.

Efficacy and tolerability of mirabegron in female patients with overactive bladder symptoms after surgical treatment for stress urinary incontinence

ABSTRACT Purpose To evaluate the efficacy and tolerability of mirabegron in females with overactive bladder (OAB) symptoms after surgical treatment for stress urinary incontinence (SUI). Materials and Methods The study was conducted with a prospective, randomized and double-blinded design. 62 patients over the age of 40 who met the inclusion-exclusion criterias of the study were enrolled and randomly divided into two groups as Group A (mirabegron 50mg) and B (solifenacin 5mg). Patients were compared based on efficacy of treatment [Patient Perception of Bladder Condition (PPBC) scale and micturition diaries], safety of treatment (heart rate, systolic and diastolic blood pressure, adverse events), number of micturitions per day, patient's satisfaction status after treatment [Visual Analog Scale(VAS)] and quality of life. Results The mean age of the population was 48.2±3.8 years and the duration of OAB symptoms was 5.9±2.9 months. Baseline values for the mean number of micturitions, volume voided in each micturition, nocturia episodes, urgency and urgency incontinence episodes were 15.3±0.34, 128±3.88mL, 3.96±1.67, 5.72±1.35 and 4.22±0.69, respectively. After treatment, values for these parameters were 11.7±0.29, 164.7±2.9mL, 2.25±0.6, 3.38±0.71, 2.31±0.49 respectively. Quality of life score, symptom bother score, VAS for treatment satisfaction score, PPBC score after treatment were 66.1±0.85, 43.7±0.77, 4.78±0.14, 4.78±0.14, respectively. There were no significant differences between two groups on any parameter. However, mirabegron showed better tolerability than solifenacin, particularly after 6 months. Conclusion Mirabegron is safe, effective and tolerable in the long-term treatment of females with OAB symptoms after surgery for stress urinary incontinence.
