ABSTRACT
Objective:To explore the efficacy and safety of robot assisted laparoscopic sacrocolpopexy in the treatment of pelvic organ prolapse.Methods:The data of 16 patients who underwent robot assisted laparoscopic sacrocolpopexy in Beijing Hospital from September 2019 to May 2022 were collected. The average age was (73.5±9.3) years, the preoperative course was 4-240 months, the body mass index was (24.2±1.7) kg/m 2, the number of births was (1.7±0.8), and the quantitative index of pelvic organ prolapse (POP-Q) was grade Ⅲ -Ⅳ. The maximum urine flow rate before operation was (9.6±3.4) ml/s, the maximum detrusor pressure during urination was 26 (20, 32) cmH 2O, the first sense urine volume of the bladder was (119.1±39.4) ml, the first sense urine urgency volume of the bladder was (253.6±75.7) ml, the maximum bladder pressure capacity was (406.0±79.8) ml, and the residual urine volume was 10 (10, 28) ml. The preoperative PFDI-20 score was 100 (70, 122) and the PFIQ-7 score was 107 (90, 160). During the robot assisted laparoscopic sacrocolpopexy, the right area of the sacral promontory was exposed, the anterior and posterior walls of the uterus were separated, and the 2 cm small hole was separated from the right broad ligament of the uterus. The mesh was cut into a "Y" shape and passed through the small hole. The anterior and posterior leaves of the Y-shaped mesh were sutured to fix the cervix, and the other end was fixed to the anterior longitudinal ligament of the sacrum. The operation time and intraoperative bleeding were observed. The effect of surgery was evaluated by preoperative and postoperative urodynamic imaging, POP-Q stage, PFDI-20 score and PFIQ -7 score. Results:All the 16 operations were successfully completed. No injury of urethra, bladder, rectum, important blood vessels and nerves occurred during the operation. The average operation time was (255.6±56.0) min, and the average amount of bleeding was (28.8±18.2) ml. There was no inhibitory contraction wave in 7 patients (44%) before operation, suggesting that there was detrusor overactivity. After operation, the detrusor overactivity disappeared or significantly decreased in 7 patients. The postoperative follow-up period was 3-36 months. During the follow-up period, one patient had recurrence, and the rest had no prolapse and urination problems. The POP-Q stage was reduced to grade 0-Ⅰ after the operation. The subjective satisfaction rate of patients was 94%. The PFDI-20 score [13(8, 24)] and PFIQ -7 score [11(6, 15)] after operation were significantly reduced ( P<0.001), the initial urgent volume of bladder (272.5±88.5) ml was significantly increased compared with that before operation ( P=0.038), and the maximum volume of bladder (427.2±79.2) ml was significantly increased compared with that before operation ( P=0.006). Image urodynamics showed that the patient basically recovered the pelvic floor anatomy and achieved functional reduction. Conclusions:Robot assisted laparoscopic sacrocolpopexy has good subjective and objective effects in POP, low recurrence rate and less complications. It needs a larger sample size study for confirming the improvement of bladder function.
ABSTRACT
Objective:To explore the potential relationship of urethral pressure profilometry and the complications of artificial urethral sphincter (AUS) implantation.Methods:The clinical data of patients who underwent AUS implantation in Beijing Hospital from March 2019 to March 2022 were retrospectively analyzed. All the patients were male. The average course of disease was 43.1 months(ranging 11-120 months). The average age was (68.6±13.2) years. The median number of pads used was 4.5 (3.0, 6.0). The preoperative maximum urethral pressure (MUP) was (84.6±25.5) cmH 2O, and the maximum urethral closure pressure (MUCP) was 51.0 (41.0, 74.0) cmH 2O. AUS implantation was performed through a single perineal incision in all patients. The sleeve size was mainly determined by the measured urethral circumference of the patient. After installation of all components, the urethral pressure profilometry was performed under the state of device inactivation and activation. The pump was activated 6 weeks after the operation, and telephone follow-up was performed 3 months after the activation of the device. The urinary control and complications were recorded. The results of follow-up were compared with the results of urethral pressure profilometry, and the preliminary conclusions were drawn. Results:In this study, 3 patients (20%) received 4.0cm cuffs, 10 patients (66.7%) received 4.5cm cuffs, and 2 patients (13.3%) received 5.0cm cuffs. The MUP and MUCP of AUS device in inactivated state were (82.5±30.2) cmH 2O and 51.0(48.0, 77.0) cmH 2O. In the activated state, MUP was (138.9±21.7) cmH 2O and MUCP was 109.0(94.0, 133.0) cmH 2O. Compared with that before operation, the urethral pressure in the inactivated state did not increase significantly (all P > 0.05), while the urethral pressure in the activated state increased significantly (all P < 0.001). The patients were followed-up for 3-33 months. Thirteen patients (86.7%) used the initial installation device, and all of them met the standard of social continence. One patient died of cerebrovascular accident. One patient took out the device due to urethral erosion. The incidence of complications was 26.7% (4/15), including painless hematuria in 2 cases, scrotum and penis infection in 1 case, and urethral erosion in 1 case. The MUP and MUCP of these patients were (100.0 ± 40.7) cmH 2O and (80.8 ± 39.7) cmH 2O respectively. In the intraoperative active state, the MUP was (151.5 ± 15.3) cmH 2O and the MUCP was (123.0 ± 17.2) cmH 2O. The MUP of the other 3 patients in the device activation state was significantly higher than the average value, and all of them were above 150 cm H 2O, except one patient who was infected due to cognitive problems and chronic urinary retention. In 11 patients without complications, the MUP and MUCP were (76.1±24.7) cmH 2O and (55.1±20.0) cmH 2O respectively. In the intraoperative active state, the MUP was (134.4±22.5) cmH 2O and the MUCP was (108.5±29.8) cmH 2O. Conclusions:AUS implantation has a definite curative effect. Poor comprehension, and MUP higher than 150 cmH 2O in the activated state of the device may be risk factors for complications.
ABSTRACT
Objective:To evaluate the efficacy and safety of robotic arm assisted laparoscopic hysterosacral fixation in patients with pelvic organ prolapse(POP), and its impact on lower urinary tract function.Methods:This study retrospectively analyzed the clinical data of POP patients who had undergone robotic arm assisted laparoscopic hysterosacral fixation at our center from June 2019 to October 2020, and conducted exploratory research.Results:A total of 6 patients were included in the study, with POP quantitative staging above stage Ⅲ.The ages ranged from 70 to 82 years.The number of births each patient had given ranged from 1 to 3, & all were via vaginal deliveries.There were no significant changes in urodynamic parameter scores in any patients before and after surgery, but half of the patients had detrusor overactivity before surgery, which all disappeared after surgery.In addition, synchronous X-ray images showed that the postoperative pelvic organs were closer to the normal anatomical position.At the same time, quantitative staging of POP had achieved clear improvement, and related scale scores also significantly improved.One patient complained of occasional lumbar and back discomfort with postoperative over-stretching during outpatient review, which improved after symptomatic treatment.Conclusions:robotic arm assisted Laparoscopic hysterosacral fixation is satisfactory in efficacy and safety for POP patients, with good postoperative restoration of the uterus to the anatomical position and has insignificant influence on the function of the lower urinary tract.It is worth further assessment for wide application.
ABSTRACT
Objective To observe the efficacy of finasteride and M-receptor antagonist (tolterodine tartrate release tablet) in patients with benign prostatic hyperplasia (BPH) with overactive bladder (OAB).Methods 40 patients with BPH and OAB were treated with finasteride (5 mg,Qd) and tolterodine tartrate release tablet (4 mg,Qd) for 6 months.The clinical effects were evaluated by the International Prostate Symptom Score (IPSS),Overactive Bladder Symptom Score (OABSS),urgency rating scale,maximum flow rate,voiding volume,prostate volume before and after treatment.Results Compared with before treatment,the IPSS,OABSS,urgency rating scale,maximum flow rate,voiding volume,prostate volume were improved [(11.8±1.4) vs.(19.2±2.1),(4.6±2.6) vs.(9.3±1.8),(1.2±1.9) times/week vs.(4.7±1.0) times/week,(14.5±2.7) ml/s vs.(10.2±2.2) ml/s,(25.2±2.6) ml vs.(34.6±3.2) m1,(46.2±2.2) ml vs.(57.6±1.3) ml,all P＜0.05] after treatment.No urinary retention and other adverse reactions were found.Conclusions Finasteride combined with M-receptor antagonist (tolterodine tartrate release tablet) is an effective and safe therapeutic method for patients with BPH and OAB.
ABSTRACT
Objective To evaluate the real-life clinical characteristics of benign prostatic hyperplasia (BPH) patients with moderate and severe enlarged prostate. Methods From February 2009 to January 2011,a prospective,non-interventional,multi-center study was conducted on 2 758 BPH patients recruited from 32 hospitals in 10 cities nationwide with the following criteria:prostate volume (PV) larger ≥30 ml and international prostate symptom score (IPSS) ≥ 8. Patient age,PV,IPSS,Qmax medical treatment patterns and physician prescription practice were recorded. The demographic information and clinic characteristics were evaluated as well. Results The mean patient age,PV,IPSS score and Qmax of 2 786eligible patients were 69.2 ±8.5 years (50 to 97 years),47.8 ±16.6 ml (30 to 165 ml),17.5 ±5.4 (8to 35 ) and 11.6 ± 3.6 ml/s (2 to 36 ml/s),respectively.Age subgroup analysis pointed that the mean PV and Qmax in 50 -55 years group were 42.8 ml and 13.3 ml/s compared to 49.0 ml and 11.1 ml/s in the group beyond 71 years.Both parameters had statistical significances (P ＜ 0.05 ). For 56.1％ of the patients,it was their first time coming to clinic seeking for medical advice. Of whom,22.8％ patients had taken BPH prescription medication regularly beyond two weeks.Only 31.3％ of the patients had a history of BPH shorter than one year.22.9％ and 18.3％ of the patients had a history of BPH for 1 -2 and 3 -4 years.And 27.5％ of the patients had a history of BPH related symptoms longer than five years. Only 52.6％ patients were treated with α adrenoceptor antagonists + 5-α reductase inhibitor by urologists according to the recommendation in Chinese guideline of BPH. Conclusions The symptoms and key parameters of moderate and severe benign prostatic hyperplasia (BPH) patients become worse and more with increased age in China.It is quite late for most patients coming to clinic seeking for their first medical advice.Furthermore,there is a huge gap between urologist prescription and the recommendation of the Chinese guideline on BPH.
ABSTRACT
Objective To evaluate the efficacy and safety of tension free vaginal tape obturator technique (TVT-O) in females stress urinary incontinence (SUI).Methods From June 2008 to May 2012,156 cases of female SUI were treated with TVT-O procedure in our hospital.The mean age is 56.3 ±13.9 years.There were 79.5％ patients who suffered simple SUI while 20.5％ patients with SUI and urge urinary incontinence (UUI).The mean follow-up time was 16.5 months.All patient’s ICI-Q-SF scores and I-QOL scores were collected.The efficacy and safety of TVT-O were analyzed.Results The mean operative time was 34 ± 11 minutes and the mean estimated blood loss were 15 ± 9 ml.One hundred and forty-five cases were cured with TVT-O (92.9％) while 8 cases were improved (5.1％).The preoperative and postoperative ICI-Q-SF symptom scores were 8.2 ± 2.1 and 0.5 ± 1.3 while the I-QOL life quality scores were 28.5 ± 10.3 and 69.8 ± 9.9 respectively.There was statistical difference between the preoperative and postoperative scores (P ＜ 0.05 ).No bladder injury was recorded during the procedures.There were two cases whose vaginal walt were injured and repaired intraoperatively.No pelvic hematoma,long-term pain,sling erosion,infection and fistula were found in all cases.Three cases ( 1.9％ ) suffered temporary urinary retention and were cured by two weeks urethral catheterization.Conclusions TVT-O technique seems to be an easy and minimally invasive procedu(r)e with less complication,which supports its safety and reliability in the treatment of female SUI.
ABSTRACT
Objective To explore the classification and risk factors of nocturia in patients with benign prostatic hyperplasia (BPH). Methods The 120 males aged 60 years old and over were enrolled who were first diagnosed as BPH or had ceased the BPH medication for at least 3 months.The patients were divided into six groups according to the nocturnal voiding episodes estimated according to the international prostate symptom score (IPSS). All 120 males were inquired about general information and medical histories. The time and volume of intake and voided urine were recorded for 72 hours. The indexes of prostate and bladder function in all cases were also examined and recorded. Results The incidence of nocturia in our study was 79.2%, the incidence of nocturnal polyuria and overactive bladder were 3.3% and 10.8%, respectively. The quality of life was affected by the duration between the time of patients' going to bed and the first time getting up at night. After excluding the cases of nocturnal polyuria and overactive bladder, statistical analysis indicated that the age, and residual urine volume of the bladder were positively associated with nocturia frequencies (NF), the nocturnal voiding volume negatively with NF, while the prostate volume and peak flow rate were not associated with NF. Drinking volume in 24-hours affected the nocturia (P＜0. 01). Conclusions Nocturia is a common complaint in elderly males with BPH and significantly affects the quality of life. The age and the storing function of bladder are more important factors as compared with prostate hyperplasia itself.
ABSTRACT
Objective To compare the urodynamic parameters in female patients with incontinence with or without pelvic organ prolapse. Methods The urodynamic data from 140 patients diagnosed urinary incontinence and another 42 patients coexisted with pelvic organ prolapse were reviewed and analyzed. The urodynamics parameters were compared in perfusion, urination, bladder compliance, maximum urinary flow rate (Qmax), detrusor muscle pressure of maximum urinary flow rate (Pdet,Qmax), minimum urinary flow rate(Pdet, Qmax), urethral resistance factor (RUA), obstruction of bladder index (OBI) and normalized detrusor contractility. The influence of pelvic organ prolapses with incontinence on bladder filling and voiding function was evaluated also.Results There were no significant differences between 140 patients of urinary incontinence and 42 patients coexisted with pelvic organ prolapse in perfusion (P=0.142), bladder compliance (P=0.273), Qmax(P=0.192),Pdet (P=-0. 629), Qmin (P=0.365) and normalized detrusor contractility (P=0.380). There were significant differences in age(P=2.2×10-5), urination(P=0.034), Pdet.Qmax(P=0.045), RUA(P=0.018), OBI (P=0.017). Conclusions There is not clinically significant change in urine storage function of bladder in patients with pelvic organ prolapse, but the parameters of voiding function of bladder may existe difference. The increased bladder outlet resistance and postvoid residual urine are noticed in patients with pelvic organ prolapse.
ABSTRACT
Objective To improve the finding of prostate cancer (PCa) and prevent the unnecessary biopsies, we select proper patients for biopsy and analyze. Methods The retrospective study included 258 patients who were biopsied for suspected early PCa. Then we analyse how the age, prostate volume, PSA, transrectal ultrasound sonography (TRUS) and MRI affect the finding of prostate cancer. Results Altogether 146 BPH and 112 prostate cancer by biopsy were detected. Positive ratio of biopsy was increased with the age or PSA increases but has no relationship with the prostate volume. Combination with digital rectal examination, PSA and TRUS, the positive ratio was improved and unecessary biopsies were avoided. The detective rate reached 84.6% when all of these three parameters were positive. The sensitivity of MRI was 98.3% but specificity was only 22.4%. The total efficacy was 21.8%. Conclusions The effect of DRE, PSA and TRUS in the screening of prostate cancer should be emphasized. However, importance of MRI is limited for the early detection of PCa.
ABSTRACT
Objective To evaluate the clinical significance of tension-free vaginal tape(TVT) procedure in the treatment with elder female stress incontinence(SUI). Methods Six patients with proven SUI were undergone the TVT with SPRAC. Results Six patients were operated under low spinal anesthesia. Mean operation time was 31.6 minutes and the mean blood loss was 36.2 ml. Five patients were able to micturate spontaneously within 24 hours after operation. One patient with fatty and vaginal colpoptosis was in-dwelling catheter for one week. Patients were followed-up for 10-28 months. Five patients were completely cured and one patient was failed after operation three months. Two patients were de novo urgency. One patient complained of persistent suprapubic discomfort. Conclusions The tension-free vaginal tape operation is a safe and effective surgical procedure for the treatment of urinary stress incontinence with fatty vaginal colpoptosis in elderly females.
