Primary Health Care nurses' role in treating Lower Urinary Tract Dysfunction / Papel de la enfermera de Atención Primaria de Salud en el tratamiento de la Disfunción del Tracto Urinario Inferior / Atuação do enfermeiro da Atenção Primária à Saúde no tratamento da Disfunção do Trato Urinário Inferior

ABSTRACT Objective: To understand Primary Health Care nurses' role in treating Lower Urinary Tract Dysfunction. Method: Cross-sectional multi-methodological research, composed of quantitative and qualitative steps, independently and sequentially. Data collected remotely, through a questionnaire and focus group, analyzed using descriptive statistics and thematic analysis by Braun and Clarke, respectively. The project was approved under Opinion 22691119.0.0000.0030. Results: A total of 145 nurses participated in the study in the quantitative step and 20 in the qualitative step, working in Primary Health Care in Brazil. Of the 93.1% nurses who reported having already cared for people with Urinary Tract Dysfunction, only 54.4% provided guidance, mainly for training the pelvic floor muscles. Conclusion: Even though they have legal support and access to demand, nurses do not have the knowledge to offer conservative treatment for Lower Urinary Tract Dysfunction. Despite this, they were motivated to do so as long as they received specific training.

Association between rectal diameter and response to treatment with parasacral transcutaneous electrical nerve stimulation and behavioral changes in children and adolescents with bladder and bowel dysfunction

ABSTRACT Purpose: Parasacral Transcutaneous Electrical Stimulation (TENS) is one of the treatments for children with Bladder and Bowel Dysfunction (BBD). Some studies showed that children with increased Rectal Diameter (RD) have more Functional Constipation (FC). However, RD prediction in maintenance of BBD after treatment was never evaluated. Our aim is to evaluate the association between RD and response to treatment in children and adolescents with BBD. Materials and Methods: This study evaluated patients from 5-17 years old with BBD. Dysfunctional Voiding Scoring System (DVSS), Rome IV criteria, and the Constipation Score were used. RD was measured using abdominal ultrasound before treatment according to the technique established by Klijn et al. and was considered enlarged when >3cm. No laxatives were used during treatment. Descriptive analysis and binary regression were performed and the area under the ROC curve was calculated. Results: Forty children were included (mean age 8.4±2.8 years, 52.5% male). Before treatment, RD was enlarged in 15 children (37.5%) (mean diameter 3.84±0.6cm), with FC persisting post-treatment in 11/15(73.3%). Those patients also required more laxatives following treatment and had more severe FC. Binary regression showed pretreatment RD to be an independent predictor of the persistence of FC post-treatment (OR=9.56; 95%CI:2.05-44.60). In ROC curve analysis, the sensitivity was 100% (95%CI: 0.49-1.0) and specificity 77.14% (95%CI:0.60-0.90) for rectal diameter >3 cm. The likelihood ratio was 4.38 (95%CI:2.40-8.0) for the persistence of BBD following treatment. Conclusion: RD appears to be relevant in the evaluation of children with BBD, not only as a diagnostic tool but also as a predictor of treatment outcome.

One-day voiding diary in the evaluation of Lower Urinary Tract Symptoms in children

ABSTRACT Introduction: Voiding diary (VD) is an important tool in the evaluation of children with voiding symptoms. Voiding frequency, maximal voided volume (MVV), average voided volume (AVV) and nocturnal volume (NV) can be extracted and are valuable in diagnosing and monitoring these disorders. Recently, ICCS has reduced the period of data recording on VD from 3 to 2 days. We hypothesized that one day voiding diary would be enough for guiding treatment. Materials and Methods: Children with overactive bladder (OAB) and primary monosymptomatic enuresis (PMNE) were oriented to fulfill a 3-day VD. Data obtained from VD were evaluated for the first day (1dVD), the first two days (2dVD), and all 3 days (3dVD) and compared according to the MVV, AVV, frequency, NV and expected bladder capacity (EBC). The Friedman, Student's t test and the Fisher's exact was used. ANOVA was used for multiple comparisons. We also used Pearson correlation test. Results: Ninety-eight children were included, 59 had PMNE and 30 OAB. Frequency, AVV and VN were similar regardless how many days the voiding episodes were recorded. Only MVV was higher by a mean of only 32 mL on 3dVD compared to 1dVD. A 1dVD has a sensitivity of 93,9% and a positive likelihood ratio of 2.2. As for the correlation of MVV and EBC it was observed that in 83% of children, MVV was lower than EBC. MVV corresponds to 67% and 69% of EBC in children with PMNE and OAB, respectively. Conclusion: We believe that 1dVD is sufficient to assess these children. It has a high sensitivity and good correlation to 3dVD in evaluating these children. Bladder capacity in this population, evaluated by maximum voided volume, was close to 68% of that obtained by the EBC.

A prospective study to evaluate the efficacy and adverse effects of alpha-blockers in the management of benign prostatic hyperplasia

Background: Benign prostatic hyperplasia (BPH) is the most common cause for the lower urinary tract symptoms in men. The conservative management of BPH comprises of alpha blockers, especially selective alpha 1 adrenergic blockers for symptomatic relief. Aims and Objectives: We aimed to evaluate the efficacy and adverse effects of alpha blockers in managing BPH. Materials and Methods: After getting approval from the Institutional Human Ethics Committee and consent from subjects, this prospective, randomized, and controlled trial was conducted. In this study, patients under inclusion criteria were divided into two groups. Group I received silodosin 8 mg once daily for 8 weeks. Group II received tamsulosin 0.4 mg once daily for 8 weeks. Primary outcome measure was reduction in international prostate symptom score (IPSS). Adverse events during study period were recorded. Results: A total of 90 patients were enrolled in this study. Ten patients were excluded and remaining 80 patients were divided as 40 in Group I (Silodosin) and 40 in Group II (Tamsulosin), patients were followed up for 8 weeks. As primary outcome, the IPSS at 8th week was significantly <0 week, that is, baseline in both the groups. The comparison of IPSS within Group I and Group II at 0 week and 8th week was significant (P < 0.05). The quality of life comparison within Group I and Group II at 0 week and 8th week was significant (P < 0.05). Both the drugs were well tolerated. Retrograde ejaculation and diarrhea were noted with silodosin (Group I), dizziness and orthostatic hypotension were noted with Tamsulosin (Group II). Conclusion: The obtained results showed that both silodosin and tamsulosin produced significant improvement in IPSS and quality of Life in BPH patients. In silodosin group, retrograde ejaculation and diarrhea were notable adverse effects and in tamsulosin group, dizziness and orthostatic hypotension were noted.

Age-related changes for the predictors of benign prostatic hyperplasia in Chinese men aged 40 years or older / 亚洲男科学杂志(英文版)

A cross-sectional study was conducted to estimate the age-stratified normal levels and age-related changes in the risk predictors of benign prostatic hyperplasia (BPH) progression. A total of 4706 male participants aged 40 years or older in Zhengzhou (China) were enrolled. The values of the International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA), prostate volume (PV), and postvoid residual urine volume (PVR) significantly increased with age. Nonlinear relationships between age and IPSS scores ≥8 (P for nonlinearity = 0.046), PSA level ≥1.6 ng ml-1, PV ≥31 ml, or PVR ≥39 ml (all P for nonlinearity <0.001) were observed. After the age of 61 years, the risk indicators related to BPH progression were positively correlated with age (odds ratio [OR] >1), regardless of the predictors of the IPSS score, PSA level, PV, or PVR; and the OR values increased gradually. Therefore, after the age of 61 years, the risk predictors related to BPH progression were positively correlated with age.

Genitourinary symptoms and quality of life of women with breast cancer undergoing chemotherapy / Síntomas genitourinarios y calidad de vida de mujeres con cáncer de mama en quimioterapia / Sintomas geniturinários e qualidade de vida de mulheres com câncer de mama em tratamento quimioterápico

ABSTRACT This study aimed to compare genitourinary symptoms and quality of life in women with breast cancer before and after chemotherapy treatment. This is a prospective and analytical study carried out with 60 women treated at a hospital in the state of Paraná. Sociodemographic data, menopausal status, climacteric symptoms, quality of life, and pelvic floor strength and resistance were collected. Descriptive statistics, t-tests, Shapiro-Wilk, Cochran, Factorial Analysis of Variance for Repeated Measures and Fishers least significance difference were used for data analysis. Participants suffered genitourinary alterations, such as reduced strength and resistance of the pelvic floor muscles, urinary incontinence and vulvovaginal atrophy, regardless of the evaluated factors (type of chemotherapy, parity, and menopausal status). Therefore, greater attention and discussion by multidisciplinary health teams is necessary, as these symptoms can be reduced and managed if recognized early.

RESUMEN Este estudio tuvo como objetivo comparar los síntomas genitourinarios y la calidad de vida en mujeres con cáncer de mama antes y después del tratamiento con quimioterapia. Se trata de un estudio prospectivo y analítico realizado con 60 mujeres que recibieron atención en un hospital del estado de Paraná (Brasil). Se recogieron datos sociodemográficos, estado menopáusico, síntomas climatéricos, calidad de vida y fuerza y resistencia del suelo pélvico. Se utilizaron estadísticas descriptivas, pruebas t de Shapiro-Wilk y de Cochran, análisis factorial de varianza para medidas repetidas y LSD-Fisher para el análisis de datos. Las participantes sufrieron alteraciones genitourinarias, como disminución de la fuerza y resistencia de los músculos del suelo pélvico, incontinencia urinaria y atrofia vulvovaginal, independientemente de los factores evaluados (tipo de quimioterapia, paridad y estado menopáusico). Se concluye que es necesaria una mayor atención y discusión por parte de los equipos de salud multidisciplinarios, ya que estos síntomas pueden reducirse y manejarse si se reconocen a tiempo.

Association between lower urinary tract symptoms and polycystic ovary syndrome

SUMMARY OBJECTIVE: The aim of this study was to analyze the association between lower urinary tract symptoms and polycystic ovary syndrome. METHODS: A total of 180 women were enrolled in this prospective study. Demographic data, body mass index, waist circumference, modified Ferriman-Gallwey scores, biochemical parameters, ultrasonographic findings, and maximum urinary flow rate (Q max) were analyzed. In addition, the Beck Depression Inventory, Beck Anxiety Inventory, and Bristol Female Lower Urinary Tract Symptom Scored Form questionnaires were evaluated for each subject. RESULTS: The mean age of patients was calculated as 23.78±3.04 years, which was similar for both groups (p=0.340). Body mass index, waist circumference, Beck Depression Inventory, Beck Anxiety Inventory, Bristol Female Lower Urinary Tract Symptom Scored Form, and modified Ferriman-Gallwey scores were significantly higher in group 2 (p<<0.001). Hyperandrogenism, lipid profile, and glucose metabolism disorders were more frequent in group 2 (p<<0.05). Bladder capacity (Q max), bladder wall thickness, and post-void residual volume values were similar in both groups (p>>0.05). CONCLUSION: In our study, a close relationship was observed between polycystic ovary syndrome and lower urinary tract symptoms. In this context, we think that a detailed urinary system evaluation of women with polycystic ovary syndrome is extremely important.

Giant multilocular prostatic cystadenoma:a case report and literature review / 现代泌尿外科杂志

【Objective】 To investigate the clinical characteristics and treatment strategy of giant multilocular prostatic cystadenoma(GMPC). 【Methods】 The clinical data of a GMPC patient treated in our hospital in July 2021 were retrospectively analyzed. The patient was 73 years old. The clinical manifestations were urgent urination and frequent urination. The prostate specific antigen (PSA) increased slightly. MRI showed giant cystic solid space occupying lesion of the prostate. Domestic and foreign cases of prostate cystadenoma from 2000 to 2021 were retrieved for literature review. 【Results】 Transabdominal laparoscopic radical prostatectomy was performed successfully. The postoperative pathological diagnosis was GMPC. Two weeks after operation, the urinary catheter was removed, and there was no discomfort such as urinary frequency or urinary incontinence. After follow-up for more than 8 months, there was no tumor recurrence or metastasis. 【Conclusion】 There are still some disputes about the oncological characteristics and diagnosis and treatment of GMPC, and there is a lack of long-term follow-up results. Laparoscopic prostatectomy is safe and feasible. Most patients have a good prognosis after surgical treatment. It is necessary to formulate an individualized standard treatment plan based on surgery combined with different patients’ conditions to actively improve the prognosis.

Prevalence and risk factors of lower urinary tract symptoms in rural children and adolescents / 现代泌尿外科杂志

【Objective】 To investigate the prevalence and risk factors of lower urinary tract symptoms (LUTS) in rural children and adolescents. 【Methods】 An epidemiological LUTS survey was carried out on 4 100 children and adolescents (aged 6-16 years) in five primary and secondary schools in rural Henan by means of stratified random cluster sampling using anonymous questionnaires. Daytime urinary incontinence (DUI), nocturnal enuresis (NE), and postnatal diaper use and toilet training were investigated. 【Results】 A total of 3 885 valid questionnaires were recovered (with a recovery rate of 94.76%). The total prevalence of the four symptoms of LUTS, including urgency, frequency, DUI and NE, were 16.42%, 10.91%, 7.41% and 7.95%, respectively. As much as 21.13% subjects had at least one symptom. The prevalence of the four symptoms decreased gradually with age, decreased sharply in those aged 6 to 12 years, and then decreased slowly. The prevalence of LUTS in children who stopped using diapers and stared urine training after 1 year of age was significantly higher than that of those within 1 year of age (χ2=21.605, 23.111, 24.189, 23.509, all P<0.05; χ2=102.17, 72.168, 53.656, 197.76, all P<0.05). There were significant differences in the prevalence of LUTS between those with and without toilet training (χ2=315.273, 198.438, 105.723, 272.502, all P<0.05). The prevalence of LUTS in males was significantly higher than that in females (P<0.05). Constipation, prepuce and phimosis in boys were significantly associated with the prevalence of LUTS (P<0.05). 【Conclusion】 Rural children and adolescents have a high prevalence of LUTS. Diaper use after 1 year of age, history of urinary tract infection (UTI), lack of toilet training, constipation, and abnormal prepuce are risk factors of LUTS. Urine training before 1 year of age is a protective factor of LUTS.

Imaging urodynamic characteristics of lower urinary tract dysfunction in young male / 现代泌尿外科杂志

【Objective】 To analyze the results, characteristics and clinical value of video urodynamic study (VUD) of lower urinary tract symptoms (LUTS) in young male. 【Methods】 A total of 106 young male LUTS patients (18-45 years old) who received VUD in our hospital during Jan.2016 and Sep.2021 were collected to analyze the clinical and imaging urodynamic characteristics. 【Results】 Of the 106 patients, 55 (52.44%) had neurogenic lower urinary tract dysfunction (NLUTD)with clear neurological etiology, and 51 (48%) had non-neurogenic lower urinary tract dysfunction (NNLUTD). In NLUTD patients, dysuria was the most common symptom (76.74%); lumbosacral lesions were the main cause (76.36%); imaging urodynamics indicated weakening of detrusor muscle in different degrees. In NNLUTD patients,the main symptoms were frequent urination (48.72%) and dysuria (48.72%); about 58.97% of patients had two or more LUTS, and the main diagnosis was detrusor underactivity (DU)(35.90%). 【Conclusion】 NLUTD in young male is characterized by varying degrees of detrusor muscle weakness, detrusor sphincter dyscoordination, and decreased bladder compliance. NNLUTD is mostly caused by detrusor overactivity (DO) and DU.

Influencing factors of lower urinary tract symptoms in patients with prostate hyperplasia after transurethral holmium laser enucleation / 中华全科医师杂志

A total of 360 patients with prostate hyperplasia underwent transurethral holmium laser enucleation of the prostate in Department of Urology of Jinhua People′s Hospital from July 2019 to December 2022. Among 360 patients, lower urinary tract symptoms occurred one month after operation in 40 cases with an incidence rate of 11.11%. The age, body mass index (BMI), course of disease, nature of disease, preoperative prostate volume, postoperative prostate volume, preoperative IPSS score, postoperative IPSS score, preoperative maximum urine flow rate, postoperative maximum urine flow rate, preoperative residual urine volume, postoperative residual urine volume, postoperative urinary tract infection, operative time, postoperative catheter retention time were compared between patients with lower urinary tract symptoms (study group) and those without (control group). There were significant differences in the course of disease, preoperative prostate volume, preoperative IPSS score, preoperative maximum urine flow rate, preoperative residual urine volume, postoperative urinary tract infection and postoperative catheter retention time between two groups ( t=28.01, 6.35, 8.79, 17.92, 34.84, 11.45;all P<0.05). Multivariate logistic analysis showed that the course of disease, preoperative prostate volume, preoperative IPSS score, postoperative urinary tract infection, and postoperative catheter retention time were independent risk factors for postoperative lower urinary tract symptoms ( OR=6.964, 3.442, 1.944, 4.836, 4.225, 4.894; all P<0.05); while the preoperative maximum urinary flow rate was the protective factor( OR=0.043, P<0.05). The incidence of postoperative lower urinary tract symptoms in patients undergoing transurethral holmium laser enucleation of prostate is high. Effective protective measures should be taken based on the risk factors to reduce the incidence of postoperative lower urinary tract symptoms and to promote the early recovery of patients.

Safety and efficacy of Rezūm water vapor thermal therapy system in the treatment of benign prostatic hyperplasia / 中华泌尿外科杂志

Objective:To evaluate the efficacy and safety of Rezūm Water Vapor Thermal Therapy system in the treatment of patients with benign prostatic hyperplasia (BPH).Methods:The clinical data of 22 patients with benign prostatic hyperplasia treated with Rezūm Water Vapor Thermal Therapy system in Boao Yiling Life Care Center in Hainan from December 2020 to January 2021 were retrospectively analyzed, with age of (61.0±5.9) years, prostate volume of (43.7±8.4) ml. international prostate symptom score (IPSS) of (19.3±3.7), quality of life (QOL) score of (4.2±0.8), maximum urinary flow rate (Q max) of (11.9±3.4) ml ml/s, and residual urine volume (PVR) of (14.0±19.0). For 19 patients with sexual life, the International Index of Erectile Function Questionnaire-5 (IIEF-5) were 17.0±5.5, the Men's Sexual Health Questionnaire-Ejaculatory Dysfunction Score (MSHQ-EjD) ejaculatory function score were 10.0±3.2, and the ejaculatory satisfaction score were 1.5±1.0. Twenty-two patients underwent Rezūm Water Vapor Thermal Therapy under intravenous anesthesia (general anesthesia without intubation) in the dorsal lithotomy position. The Rezūm system consisted of reusable thermal steam treatment device and disposable prostate thermal steam treatment instrument. The thermal steam treatment device used radiofrequency energy to heat sterile distilled water, generating high-temperature steam at 103℃. In a 9-second timeframe, the tissue temperature within each treatment area was raised approximately 70℃, causing cell death and resulting in a shrink in prostate tissue volume. The disposable prostate thermal steam treatment instrument could be inserted through a cystoscope and had a retractable needle tip that extends to a length of 10.25 mm. The needle tip had 12 evenly distributed holes arranged in three rows of four holes each, with a spacing of 120° between rows, allowing for even diffusion of thermal steam along the circumference. The patient was placed in a lithotomy position, and the disposable prostate thermal steam treatment instrument was used to examine the prostate, urethra, and bladder via cystoscopy, assessing the lateral lobes and median lobe of the prostate. The tissue spacing within each field of view of the treatment instrument is 0.5 cm, and the distance from the bladder neck to the verumontanum is calculated. The first needle was injected at 3 o’clock along the left lobe, withdrawing 2 fields of view each time. During the release of thermal steam, the needle tip was positioned perpendicular to the prostate urethral mucosa, and each needle injection delivered 0.42 ml of sterile distilled water-formed thermal steam into the prostate tissue. The thermal steam injection lasted for 9 seconds, followed by a 2-3 seconds waiting period before retracting the needle tip. One needle was injected per 2 fields of view, progressing towards the proximal urethra of the verumontanum. The same method was used to treat the right lobe. For cases with significant median lobe enlargement, two fields of view were retracted at the bladder neck, and the needle was inserted at a 45° angle. The second needle was injected at intervals determined by the extent of median lobe enlargement. Each puncture point was observed for no significant bleeding, and the instrument was then removed, with an F16/F18 silicone catheter left in place. The operative time as well as indwelling catheter time were recorded. The clinical parameters such as IPSS, QOL, prostate volume, Qmax, PVR, QOL, IIEF-5 and MSHQ-EjD at preoperative and 12 to 22 weeks post operation were compared. Adverse events from the Rezūm procedure to 12-22 weeks postoperatively were recorded. Results:All the operations were successfully completed. The operation time of Rezūm system was 3.9±1.6 min, and the indwelling catheter time after operation was 4.8±1.1 days. The IPSS scores of 22 patients at 12-22 weeks after operation were 4.4±3.3, whose reduction was 14.9±4.4 compared with these at baseline( P<0.01). The PV was (37.7±8.4)ml, Qmax was (25.5±9.6)ml/s, PVR was (6.2±8.1)ml, and QOL was 1.6±0.9, all demonstrating statistically significant differences compared to preoperative values ( P<0.05). Among the 19 cases with sexual activity, the IIEF-5 score was 20.4±3.2, and the ejaculatory function score of MSHQ-EjD was 13.1±3.1, both showing statistically significant differences compared to preoperative scores ( P<0.05). The ejaculatory satisfaction score of MSHQ-EjD was 1.1±0.5, and there was no statistically significant difference compared to preoperative scores ( P>0.05). None of the 22 cases required medication or further surgical treatment for BPH after surgery. There were no urethral injuries, rectal or bladder perforations during the surgeries, and no severe complications such as rectal fistula or bladder neck contracture occurred postoperatively. There were no deaths reported. Postoperative discomfort in the urethra occurred in 19 cases, urethral pain in 8 cases, hematuria in 15 cases, poor sleep quality in 2 cases, and constipation in 1 case, all of which resolved within 7 to 10 days after surgery. Erectile dysfunction and retrograde ejaculation occurred in one case each at 4 to 5 weeks postoperatively but did not reoccur thereafter. Prostatitis and nodular hyperplasia of the middle lobe of the prostate occurred in one case each at 21 weeks and 25 weeks postoperatively, respectively, and no treatment was administered. Conclusions:In the real world, the short-term overall effect of Rezūm Water Vapor Thermal Therapy system in the treatment of benign prostatic hyperplasia is satisfactory, which shows good efficacy and safety.

Lower urinary tract symptoms in Parkinson's disease and multiple system atrophy / 中华老年医学杂志

Parkinson's disease(PD)and multiple system atrophy(MSA)are two common Parkinsonian syndromes with overlapping clinical manifestations, and clinical differential diagnosis is difficult.Lower urinary tract symptoms are one of the common non-motor symptoms of the two diseases.The incidence of lower urinary tract symptoms in MSA is higher, the onset is earlier, and the micturition period is more prominent.The urinary dysfunction in patients with PD is mainly caused by the central mechanism, leading to overactive bladder.MSA has more extensive lesions with both central and peripheral involvement, leading to overactive bladder and severe voiding dysfunction.Urodynamics can be used to evaluate bladder and urethral function.MSA has more prominent weak detrusor activity, residual urine volume, and early changes of urethral sphincter.The treatment of lower urinary tract symptoms in patients with PD is mainly based on anticholinergic drugs to improve overactive bladder, while in MSA patients with increased residual urine volume, intermittent catheterization is the main method to improve lower urinary tract symptoms.This article reviewed the epidemiology, pathological mechanism, urodynamics and treatment of lower urinary tract symptoms of the two diseases, so as to assist in their differential diagnosis and treatment.

The Effects of Hysterectomy on Urinary and Sexual Functions of Women with Cervical Cancer: A Systematic Review / Os efeitos da histerectomia nas funções urinárias e sexuais de mulheres com câncer cervical: Uma revisão sistemática

Abstract Objective This systematic review aims at describing the prevalence of urinary and sexual symptoms among women who underwent a hysterectomy for cervical cancer. Methods A systematic search in six electronic databases was performed, in September 2019, by two researchers. The text search was limited to the investigation of prevalence or occurrence of lower urinary tract symptoms (LUTS) and sexual dysfunctions in women who underwent a hysterectomy for cervical cancer. For search strategies, specific combinations of terms were used. Results A total of 8 studies, published between 2010 and 2018, were included in the sample. The average age of the participants ranged from 40 to 56 years, and the dysfunctions predominantly investigated in the articles were urinary symptoms (n= 8). The rates of urinary incontinence due to radical abdominal hysterectomy ranged from 7 to 31%. The same dysfunction related to laparoscopic radical hysterectomy varied from 25 to 35% and to laparoscopic nerve sparing radical hysterectomy varied from 25 to 47%. Nocturia ranged from 13%, before treatment, to 30%, after radical hysterectomy. The prevalence rates of dyspareunia related to laparoscopic radical hysterectomy and laparoscopic nerve sparing radical hysterectomy ranged from 5 to 16% and 7 to 19% respectively. The difficulty in having orgasm was related to laparoscopic radical hysterectomy (10 to 14%) and laparoscopic nerve sparing radical hysterectomy (9 to 19%). Conclusion Urinary and sexual dysfunctions after radical hysterectomy to treat cervical cancer are frequent events. The main reported disorders were urinary incontinence and dyspareunia.

Resumo Objetivo Essa revisão sistemática visa descrever a prevalência de sintomas urinários e sexuais entre mulheres submetidas à histerectomia por câncer cervical. Métodos Uma pesquisa sistemática foi realizada em seis bases de dados eletrônicas, em setembro de 2019, por dois pesquisadores. A busca foi limitada à investigação da prevalência e ocorrência de sintomas do trato urinário baixo e disfunções sexuais em mulheres após histerectomia por câncer cervical. Como estratégia de busca foi utilizada uma combinação específica de termos apenas em inglês. Resultados Um total de 8 estudos, publicados entre 2010 e 2018, foram incluídos na amostra. A idade média dos participantes foi de 40 a 56 anos, e as principais disfunções investigadas pelos artigos foram sintomas urinários (n= 8). Na literatura analisada, as taxas de incontinência urinária ligadas à histerectomia abdominal radical variaram de 7 a 31%. A mesma disfunção, para histerectomia radical laparoscópica, variou de 25 a 35%, e de 25 a 47% para histerectomia radical laparoscópica poupadora de nervo. A taxa de noctúria variou de 13%, antes do tratamento, a 30%, após histerectomia radical. A prevalência de dispareunia associada à histerectomia radical laparoscópica foi de 5 a 16%. Já a taxa de dispareunia relatada pós-histerectomia radical laparoscópica poupadora situou-se entre 7 e 19%. A dificuldade de alcançar o orgasmo foi relatada após histerectomia radical laparoscópica, variando de 10 a 14%, e também na histerectomia radical laparoscópica poupadora de nervo, variando de 9 a 19%.

Lower urinary system symptoms and affecting factors in female students staying in a dormitory

SUMMARY OBJECTIVE: The aim of the study was to determine the lower urinary system symptoms and the factors affecting it among young women living in the dormitory. METHODS: This is a descriptive and cross-sectional study. A total of 355 women attending education in a public university were interviewed, considering a 95% confidence interval. Data were collected using the descriptive form and the Bristol Female Lower Urinary Tract Symptoms Scale. Necessary permissions were obtained, and appropriate analyses were carried out using the SPSS-22 program. RESULTS: Findings showed that 71.6% of women have problems with urine storage, 29.7% have urinating disorders, 18.4% have urinary incontinence, 8.8% have sexual life problems, and 37.2% have symptoms related to quality of life. Factors affecting the symptoms include history of chronic disease (such as neurological diseases and depression), smoking, low income, history of urinary incontinence in childhood, the presence of symptoms in the mother or family history, the presence and number of urinary tract infections, chronic constipation, and not paying attention to toilet cleaning. CONCLUSION: It is recommended to carry out community-based studies to raise awareness of women, support priority risk groups by screening, and increase the number of specialist healthcare personnel for quality care and treatment.

Is biofeedback-assisted pelvic floor muscle training superior to pelvic floor muscle training alone in the treatment of dysfunctional voiding in women? A prospective randomized study

ABSTRACT Purpose: To compare the effectiveness of biofeedback-assisted pelvic floor muscle training (PFMT) and PFMT alone on voiding parameters in women with dysfunctional voiding (DV). Materials and Methods: The patients in group 1 (34 patients) were treated with biofeedback-assisted PFMT, and the patients in group 2 (34 patients) were treated with PFMT alone for 12 weeks. The 24-hour frequency, average voided volume, maximum urine flow rate (Qmax), average urine flow rate (Qave), post-void residual urine volume (PVR), and the validated Turkish Urogenital Distress Inventory (UDI-6) symptom scores were recorded before and after 12 weeks of treatment. Results: At the end of treatment sessions, the Qmax and Qave values of the patients in group 1 were significantly higher than those in group 2, and the PVR in the patients in group 1 was significantly lower than those in group 2 (p=.026, .043, and .023, respectively). The average UDI-6 symptom scores of the patients in group 1 were significantly lower than those in group 2 (p=.034). Electromyography activity during voiding, in group 1 was significantly lower than in group 2 (41.2 vs. 64.7, respectively, p=.009). Conclusion: Biofeedback-assisted PFMT is more effective than PFMT alone in improving clinical symptoms, uroflowmetry parameters, and EMG activity during voiding.

Could urinary nerve growth factor and bladder wall thickness predict the treatment outcome of children with overactive bladder?

ABSTRACT Objective: Bladder wall thickness (BWTh) measurements and Nerve Growth Factor (NGF) /creatinine (Cr) values, as noninvasive tools, were found to predict daytime voiding problems in children with overactive bladder (OAB). The goal of this research was to examine if bladder wall thickness together with urine NGF/Cr could be a clinical utility in treatment outcome of OAB in children. Patients and Methods: A total of 60 children with OAB, (Group 1; n=40) and healthy normal controls (Group 2; n=20), aged 6-14 years old were involved in this prospective study. Children were evaluated with detailed history and physical examination, including neurologic examination, and were asked to complete a self-reported questionnaire and a 3-day bladder diary with the aid of their parents. Uroflowmetry was performed in all cases. Urinary nerve growth factor levels were measured by the ELISA and BWTh was measured trans-abdominally by one uro-radiologist specialized in pediatric ultrasonography. Urinary NGF levels were normalized by urinary creatinine levels and compared among all subgroups. Children with OAB received urotherapy as first line treatment at least for three months. 18 children refractory to urotherapy received anticholinergic therapy defined as group 3. Results: The median age of the study group was 10 (range 6 to 16). After urotherapy, 22 children had similar BWTh and NGF/Cr values compared to controls. (2.75 ± 1.15; 2.40 ± 1.00 mm; p=0.86 and 1.02 ± 0.10; 0.78 ± 0.15; p=0.12, respectively). After anticholinergic treatment, BWTh levels (2.25 ± 0.90; 2.40 ± 1.00 mm; p=0.94) and NGF/Cr values (0.95 ± 0.10; 0.78 ± 0.15; p=0.42, respectively) had no significantly difference compared to controls (Group 2). In receiver operating characteristic analysis, bladder wall thickness was found to have sensitivity of 85% and specificity of 84.2% (3,20 AUC, 913; 95 %) and NGF/Cr had sensitivity of 90% and specificity of 92.1% (1,595; AUC, 947; 95 %) in predicting treatment outcome in children with OAB. Conclusions: Bladder wall thickness measurements and NGF/Cr values, as noninvasive tools, could guide outcomes in the treatment of children with overactive bladder.

Estudo Comparativo Entre Diário Vesical e Estudo Urodinâmico para Identificação de Sintomas do Trato Urinário Inferior / Comparative Study Between Bladder Diary and Urodynamic Study to Identify Lower Urinary Tract Symptoms / Estudio Comparativo Entre el Diario Vesical y el Estudio Urodinámico para Identificar los Síntomas del Tracto Urinario Inferior

Objetivo:Avaliar a efetividade do diário vesical para identificar sintomas do trato urinário inferior, em comparação ao estudo urodinâmico. Método: Trata-se de estudo observacional de corte transversal realizado em uma clínica de urodinâmica do sul catarinense com 44 pacientes submetidos ao exame. A coleta de dados deu-se por aplicação de questionário de dados epidemiológicos e de sintomas e diário vesical de 72 horas e comparação deste com os achados do estudo urodinâmico por meio do programa Stata/SE v.14.1. Resultados: O diário vesical apresentou alta especificidade, sensibilidade e acurácia para identificação de hiperatividade detrusora e incontinência urinária de esforço. Não apresentou diferença para capacidade vesical (p* 0,198) e apontou sensibilidade vesical com volume menor do que o apresentado pelo estudo urodinâmico (p*<0,001). Foi capaz de identificar sintomas de trato urinário inferior que não haviam se revelado no estudo urodinâmico. Conclusão: O diário vesical mostrou-se tão efetivo quanto o estudo urodinâmico para identificação de sintomas de trato urinário inferior, podendo ser utilizado para definição de tratamento de primeira linha com maior abrangência de diagnóstico populacional, menor tempo entre queixa e tratamento, redução de custo para o sistema e menor desconforto para o paciente.

Objective:To identify the similarity of lower urinary tract symptoms presented in the urodynamic study compared to the urinary diary. Method: This is a comparative study carried out in an urodynamics clinic in southern Santa Catarina, Brazil, with 44 patients who underwent the examination. Data collection was carried out by applying a questionnaire and a 72-hour bladder diary and comparing it with the findings of the urodynamic study using the SPSS for Windows and Stata/SE v.14.1 programs. Results: The bladder diary showed high specificity, sensitivity, and accuracy for identifying detrusor hyperactivity and stress urinary incontinence. There was no difference for bladder capacity (p* 0.198). It pointed to bladder sensitivity with a volume smaller than that presented by the urodynamic study (p*<0.001). It was able to identify lower urinary tract symptoms that were not present in the urodynamic study. Conclusion: The bladder diary was effective for identifying lower urinary tract symptoms and can be used to define first-line treatment with a broader range of population diagnosis, shorter time between complaints and treatment, cost reduction for the system, and less discomfort for the patient.

Factors predicting the development of urethral stricture after bipolar transurethral resection of the prostate

SUMMARY OBJECTIVE: We aimed to investigate the rate of urethral stricture development, predictor factors, and the reliability following bipolar transurethral resection of the prostate. METHODS: A total of 124 patients participated in this study. Patient data were retrospectively reviewed. The patients were divided into group 1 (those who developed urethral stricture) and group 2 (those who did not develop urethral stricture). Annual checkups were performed after the postoperative months 1 and 6. The patients were checked by uroflowmetry + post-voiding residue and international index of erectile function. We evaluated the complications that developed during the perioperative period according to the Clavien system. RESULTS: Urethral stricture developed in 10.5% (13/124) of the patients. It was found that patients who underwent transurethral resection of the prostate for the second time (p=0.007), patients with a preoperative catheter or history of catheter insertion (p=0.009), patients with high preoperative median white blood cell (103) counts (p=0.013), and patients with long postoperative catheterization time had a higher rate of urethral stricture after bipolar transurethral resection of the prostate (p=0.046). No grade 4 and grade 5 complications were observed according to the Clavien system in patients. CONCLUSION: Factors such as second transurethral resection of the prostate surgery, history of preoperative catheter insertion, high postoperative white blood cell count, and long postoperative catheterization time increase the risk of urethral stricture after bipolar transurethral resection of the prostate.
