RESUMO

Cancer spread beyond the prostate, including extraprostatic extension (other than seminal vesicle or bladder invasion; EPE)/microscopic bladder neck invasion and seminal vesicle invasion (SVI) currently classified as pT3a and pT3b lesions, respectively, does not uniformly indicate poor oncologic outcomes. Accurate risk stratification of current pT3 disease is therefore required. We herein further determined the prognostic impact of these histopathologic lesions routinely assessed and reported by pathologists, particularly their combinations. We assessed consecutive 2892 patients undergoing radical prostatectomy for current pT2 (n = 1692), pT3a (n = 956), or pT3b (n = 244) disease at our institution between 2009 and 2018. Based on our preliminary findings, point(s) were given (1 point to focal EPE, microscopic bladder neck invasion, or unilateral SVI; 2 points to nonfocal/established EPE or bilateral SVI) and summed up in each case. Our cohort had 0 point (n = 1692, 58.5%; P0), 1 point (n = 243, 8.4%; P1), 2 points (n = 657, 22.7%; P2), 3 points (n = 192, 6.6%; P3), 4 points (n = 76, 2.6%; P4), and 5 points (n = 32, 1.1%; P5). Univariate analysis revealed associations of higher points with significantly worse biochemical progression-free survival, particularly when P4 and P5 were combined. In multivariable analysis (P0 as a reference), P1 (hazard ratio [HR], 1.57; P = .033), P2 (HR, 3.25; P < .001), P3 (HR, 4.01; P < .001), and P4 + P5 (HR, 5.99; P < .001) showed significance for the risk of postoperative progression. Meanwhile, Harrell C-indexes for the current pT staging, newly developed point system, and the Cancer of the Prostate Risk Assessment post-Surgical (CAPRA-S) score were 0.727 (95% CI, 0.706-0.748), 0.751 (95% CI, 0.729-0.773), and 0.774 (95% CI, 0.755-0.794), respectively, for predicting progression. We believe our data provide a logical rationale for a novel pathologic T-staging system based on the summed points, pT1a (0 point), pT1b (1 point), pT2 (2 points), pT3a (3 points), and pT3b (4 or 5 points), which more accurately stratifies the prognosis of prostate cancer.

RESUMO

PURPOSE: Bladder neck stricture (BNS) is a bothersome disease which may affect patients after trauma or prostatic surgery. It is frustrating due to the low durable success rate of currently available surgical techniques. The aim of the study is to explore the efficacy of a novel technique. MATERIALS & METHODS: The surgical protocol was developed by two high case-volume surgeons. The technique consists of Holmium laser incisions at 3-6-9-12 o'clock. Subsequently, triamcinolone acetonide 40 mg is injected. Two months later, the BNS is endoscopically checked in operatory room and re-procedure take place, if necessary (max 3 times). Failure was defined as the need of definitive urinary diversion. Subjective satisfaction was measured through PGI-I Questionnaire. RESULTS: A total of 45 patients were enrolled. Median age was 63 (IQR 59-69) years and BNS developed by different causes. Naïve BNS procedure patients were 12 (26.7%), others 33 (73.3%) underwent median 2 (IQR 1-4) previous urethrotomies, including 16 other surgeries. Suprapubic bladder catheter was present in 34 patients (75.6%). No complications were registered. Re-procedure at control was necessary in 24 patients (53.3%) for a median of 1 (IQR 1-3) procedures. At median follow-up of 18 months, failures were 4 (8.9%) and urinary incontinence was reported in 2 patients (4.5%) who required incontinence surgery. Median PGI-I was 2. CONCLUSIONS: Our technique of BNS treatment allows good outcomes and high rate of subjective improvement amongst patients. Moreover, naïve patients seem to have better results. However, longer follow-up and higher sample size are mandatory to further assess these data.

RESUMO

PURPOSE: To compare the outcomes of patients undergoing robotic YV plasty for bladder neck contracture (BNC) vs. vesico-urethral anastomotic stricture (VUAS). METHODS: A retrospective study included male patients who underwent robotic YV plasty for BNC after endoscopic treatment of BPH or VUAS between August 2019 and March 2023 at a single academic center. The primary assessed was the patency rate at 1 month post-YV plasty and during the last follow-up visit. RESULTS: A total of 21 patients were analyzed, comprising 6 in the VUAS group and 15 in the BNC group. Patients with VUAS had significantly longer operative times (277.5 vs. 146.7 min; p = 0.008) and hospital stay (3.2 vs. 1.7 days; p = 0.03). Postoperative complications were more common in the VUAS group (66.7% vs. 26.7%; p = 0.14). All patients resumed spontaneous voiding postoperatively. Five patients (23.8%) who developed de novo stress urinary incontinence had already an AUS (n = 1) or required concomitant AUS implantation (n = 3), all of whom were in the VUAS group (83.3% vs. 0%; p < 0.0001). The proportion of patients improved was similar in both groups (PGII = 1 or 2: 83.3% vs. 80%; p = 0.31). Stricture recurrence occurred in 9.5% of patients in the whole cohort, with no significant difference between the groups (p = 0.50). Long-term reoperation was required in three VUAS patients, showing a statistically significant difference between the groups (p = 0.05). CONCLUSION: Robotic YV plasty is feasible for both VUAS and BNC. While functional outcomes and stricture-free survival may be similar for both conditions, the perioperative outcomes were less favorable for VUAS patients.

RESUMO

PURPOSE: Bladder neck contracture (BNC) is a rare but intolerant complication after transurethral surgery of prostate. The present study aims to investigate the incidence and risk factors of BNC in patients diagnosed benign prostate hyperplasia (BPH) and following transurethral resection or enucleation of the prostate (TURP/TUEP). METHODS: This retrospective study included 1008 BPH individuals who underwent transurethral surgery of the prostate between January 2017 and January 2022. Patients' demographics, medical comorbidities, urologic characteristics, perioperative parameters, and the presence of BNC were documented. Univariate and multivariate analyses were conducted to identify the risk factors. RESULTS: A total of 2% (20/1008) BPH patients developed BNC postoperatively and the median occurring time was 5.8 months. Particularly, the incidences of BNC were 4.7% and 1.3% in patients underwent Bipolar-TURP and TUEP respectively. Preoperative urinary tract infection (UTI), elevated PSA, smaller prostate volume (PV), bladder diverticulum (BD), and B-TURP were significantly associated with BNC in the univariate analysis. Further multivariate logistic regression demonstrated preoperative UTI (OR 4.04, 95% CI 2.25 to 17.42, p < 0.001), BD (OR 7.40, 95% CI 1.83 to 31.66, p < 0.001), and B-TURP (OR 3.97, 95% CI 1.55 to 10.18, p = 0.004) as independent risk factors. All BNC patients were treated with transurethral incision of the bladder neck (TUIBN) combined with local multisite injection of betamethasone. During a median follow-up of 35.8 months, 35% (7/20) of BNC patients recurred at a median time of 1.8 months. CONCLUSION: BNC was a low-frequency complication following transurethral surgery of prostate. Preoperative UTI, BD, and B-TURP were likely independent risk factors of BNC. TUIBN combined with local multisite injection of betamethasone may be promising choice for BNC treatment.

RESUMO

INTRODUCTION: Bladder outlet obstruction (BOO) in women includes functional and anatomic etiologies. Primary bladder neck obstruction (PBNO), Fowler's syndrome (FS), and dysfunctional voiding (DV) are some examples of functional obstructions, whereas pelvic organ prolapse (POP), periurethral masses, and intragenic causes are some of the anatomic causes. METHODS: This literature review describes the etiologies of female BOO, unique aspects of the workup and diagnosis, and the data for the standard surgical treatments and newer surgical techniques to treat women. Urethral stenosis and sling-related obstruction are treated in the other articles of this series. Where possible the focus is the efficacy and outcomes. RESULTS: Treatment of PBNO using a transurethral incision of the bladder neck and injection of botulinum toxin in the bladder neck decreases the BOO. After the failure of conservative approaches, sacral neuromodulation (SNM) is effective for FS, while DV may benefit from SNM or botulinum toxin injections. Concerning POP, most surgeries have been reported to significantly improve a pre-existent BOO but the level of evidence is low. Benign urethral and periurethral masses may provoke BOO, and surgical excision usually resolves this condition. CONCLUSION: Although most surgical treatments of BOO for functional and benign anatomical etiologies in women seem to be effective, data are scarce even for more common conditions like POP. Further studies are required to give better advice on the choice of surgical technique for these patients.

RESUMO

OBJECTIVE: Primary bladder neck obstruction (PBNO) is a condition primarily affecting young men, characterized by obstruction at the bladder neck, leading to lower urinary tract symptoms. The aim of this study was to identify a correlation between the severity of bladder neck opening impairment and urinary symptoms by means of urodynamic studies. MATERIALS AND METHODS: A retrospective analysis was conducted in adult males diagnosed with PBNO at a university neurourology department between 2015 and 2022 who underwent voiding cystourethrography (VCUG) and pressure-flow studies. The cohort was divided into two groups: absence of bladder neck opening on VCUG (Group A) and incomplete bladder neck opening (Group B). RESULTS: Out of the 82 patients with PBNO screened, 53 were included in the analysis. Nocturia was the only symptom more prevalent in Group A (65% in Group A vs. 30% in Group B, p = 0.02) but scores and subscores of the Urinary Symptom Profile questionnaire were not different between groups. In addition, the detrusor pressure at a maximum flow rate (PdetQmax), bladder outlet obstruction index (BOOI), and bladder contractility index (BCI) were higher in Group A than in Group B [PdetQmax (A = 93.7 ± 53.7 cmH2O vs. B = 65.7 ± 26.4 cmH2O; p = 0.01)-BOOI (A = 77 ± 58.3 vs. B = 48 ± 25.7; p = 0.03)-BCI (A = 136 ± 51.3 vs. B = 110 ± 41.7; p = 0.04)]. CONCLUSION: This study demonstrates a significant association between the extent of bladder neck opening impairment observed on VCUG and obstruction and contraction urodynamic parameters, but no association with the severity of urinary symptoms. Future studies should evaluate the predictive value of treatment response and the occurrence of complications based on clinical and urodynamic parameters.

RESUMO

Urethral injuries are rare among the pediatric population, and the majority occur after trauma. This is the case of an eight-year-old female with complete proximal urethral disruption and ruptured bladder neck without pelvic fracture after a motor vehicle crash. After the accident, her bladder neck was reapproximated and a suprapubic tube was placed. Three months later, she underwent reconstruction for a bladder neck closure and appendicovesicostomy. In managing these patients, focus should first be directed at achieving a safe means of urinary drainage, and next to repair the lower urinary tract to maximize continence and minimize complications.

RESUMO

OBJECTIVES: This study was to evaluate the application of automatic measurement based on convolutional neural network (CNN) technology in intracavitary ultrasound cine of anterior pelvic. METHODS: A total of 500 patients who underwent pelvic floor ultrasound examination at Peking University Shenzhen Hospital from July 2021 to February 2022 were retrospectively retrieved by the picture archiving and communication system (PACS) system, and 300 cases were used as a training set. The training set was labeled by three experienced ultrasound physicians to train CNN models and develop an automatic measurement software. The remaining 200 cases were used as a test set. Automatic measurement software identified relevant anatomical structures frame by frame and determined the two frames with the greatest difference, calculated the bladder neck descent (BND), urethral rotation angle (URA), and retrovesical angle (RA). Meanwhile, two experienced ultrasound physicians evaluated the resting frame and the maximum Valsalva frame on the cines by manual visual evaluation, labeled the anatomical structures in the corresponding frame, such as the inferoposterior margin of pubic symphysis, the mid-axis of pubic symphysis, bladder contour, and urethra in the front, and calculated BND, URA, and RA. Considering that the residual urine volume (RUV) in the bladder may affect the results, enrolled patients were grouped according to the RUV (10-50 mL, 50-100 mL, and >100 mL). The consistency of the results by automatic measurement and manual visual evaluation was evaluated using the intraclass correlation coefficient (ICC) and the Bland-Altman graph. RESULTS: Of the 200 cases in the test set, 120 cases were successfully identified by the CNN automatic software with a 60% recognition rate. In the case of successful identification, the ICC of manual visual evaluation measurement and automatic measurement was 0.936 (BND), 0.911 (URA), 0.756 (RA in rest), and 0.877 (RA at maximum Valsalva), respectively. In addition, the RUV had a negligible effect on the consistency. The Bland-Altman plot shows the proportion of samples outside the limit was below 5%. CONCLUSIONS: CNN-based automatic measurement software exhibited high reliability in anterior pelvic measurement, which results in a significantly enhanced measurement efficiency.

RESUMO

INTRODUCTION: Benign prostatic enlargement (BPE) and lower urinary tract symptoms present challenges in aging men, often addressed through transurethral resection of the prostate (TURP). Despite technological advancements, bladder neck contracture (BNC) remains a concern. This study explores predictors, including comorbidities, influencing BNC after TURP. METHODS: A retrospective cohort study at Changhua Christian Hospital analyzed 2041 BPE patients undergoing bipolar TURP. Preoperative urinary catheterization and resection speed were categorized. Patient data included demographics, comorbidities, operative details, and outcomes. Statistical analyses utilized χ2, Kruskal-Wallis tests, and Cox regression models. RESULTS: Within 3 years, 306 (15%) patients developed BNC. Univariate Cox regression identified chronic heart failure (p = 0.033), chronic obstructive pulmonary disease (COPD; p = 0.002), preoperative urinary catheterization (p < 0.001), and low resection speed (p = 0.045) as significant BNC risk factors. Notably, COPD (p = 0.011) and preoperative urinary catheterization (p < 0.001) emerged as independent risk factors for BNC development in multivariate Cox regression analysis. CONCLUSIONS: Preoperative urinary catheterization and COPD were significant predictors of BNC post-TURP, while resection speed showed no significant influence. These findings offer clinicians insights for risk assessment, enhancing patient outcomes, and optimizing resources post-TURP.

RESUMO

PURPOSE: This study describes the management of urinary incontinence (UI) in eight girls with congenital pouch colon (CPC) associated with anorectal malformation (ARM). METHODS: From 2013 to 2015, six girls with CPC and UI underwent bladder neck reconstruction (BNR). Four girls had complete UI (CUI) and two girls partial UI (PUI). From 2019 to 2023, four girls, including two with failed BNR, underwent bladder neck closure (BNC) and augmentation cystoplasty (AC) with a continent stoma. Subtypes of CPC were Complete CPC (n = 7) and Incomplete CPC (n = 1). All girls had a double vagina; short, wide urethra; and reduced bladder capacity with an open, incompetent bladder neck (BNI). During BNR, a neourethra was constructed from a 1.5-2 cm-wide and 1.5-3-cm-long trigonal strip. During BNC, AC was performed using a 20 cm ileal segment (n = 3) and by a colonic pouch segment, preserved during earlier colorraphy (n = 1). Continent stoma included a Monti's channel (n = 3) and appendicovesicostomy (n = 1). RESULTS: BNR produced moderate improvement of UI (n = 2), while UI was still very severe (n = 4). During BNC, intraoperative complications included iatrogenic vaginal tears (n = 4). Early complications included partial dehiscence of the ileocystoplasty (n = 1), partial adhesive small bowel obstruction (n = 1), and difficulty in stomal catheterization with prolonged drainage from the pelvic drain (n = 1). Late complications included unilateral grade II vesicoureteric reflux (n = 2) and vesicovaginal fistula (VVF) (n = 2) needing trans-vaginal closure in one girl. Urinary stones (n = 2) with stomal leakage of urine in one girl needed open cystolithotomy twice (n = 1), and endoscopic lithotripsy (n = 1). At follow-up, all patients have high overall satisfaction with the procedure and their continence status. CONCLUSIONS: BNC with AC and a catheterizable stoma satisfactorily achieves continence in girls with CPC and UI, vastly improving quality of life. If lower urinary tract (LUT) anatomy is favorable, BNR with/without AC can be the initial surgical procedure. BNC should be the primary procedure in girls with unfavorable LUT anatomy and for failed BNR. LEVEL OF EVIDENCE: IV.

RESUMO

INTRODUCTION: The preservation of the bladder neck during robot-assisted radical prostatectomy (RARP) could improve urinary continence recovery and limit the risk of positive surgical margins (PSMs). We refined our lateral approach to the bladder neck technique and compared its outcomes with those of the standard anterior approach. MATERIAL AND METHODS: From a retrospective analysis of 599 consecutive RARPs, 171 patients treated with the lateral and 171 patients treated with the anterior approach were pair-matched 1:1 on the basis of age, grade, and pathological stage. We described our surgical technique and compared the two approaches in terms of basal PSMs, recovery of urinary continence, and complications. RESULTS: As compared to the anterior approach, the lateral approach had shorter operative times and comparable rates of basal PSMs and postoperative complications. The rates of urinary continence after one, three, and 12 months were comparable between the two groups and were generally higher in localized disease. At regression analysis, predictors of urinary incontinence were only age, pathological stage T3b, ISUP grade 5 and nerve-sparing surgery. CONCLUSIONS: The lateral approach leads to an anatomical dissection of the bladder neck without increasing the risk of PSMs. However, no significant benefits in terms of continence recovery were demonstrated over the standard anterior approach.

RESUMO

Urinary incontinence (UI) is a common health condition that may interfere with the quality of life. A comprehensive evaluation of female UI helps with effective and safe treatments. Ultrasound has gained popularity to explore UI recently because it can collect crucial information for treatment planning and counseling. Translabial and introital approaches are commonly and reliably applied to ultrasound. The images can be obtained using two-dimensional and three-dimensional ultrasounds. Ultrasound is the only modality capable of confirming the presence or absence of a mid-urethral sling (MUS) and is able to demonstrate bulking agents as well. Although some of the ultrasound findings may only be incidental or supplementary to the patient's symptoms, ultrasound benefits for investigating the pathophysiology of UI and surgical outcomes of MUS procedures. It is anticipated that standardization in terminology, measurement techniques, and reporting can be established in the near future.

RESUMO

INTRODUCTION: Transurethral resection of the prostate (TURP) is the most frequently used treatment of benign prostate hyperplasia with a prostate volume of <80 mL. A long-term complication is bladder neck contracture (BNC). The aim of the present study was to identify the risk factors for BNC formation after TURP. METHODS: We conducted a retrospective analysis of all TURP primary procedures which were performed at one academic institution between 2013 and 2018. All patients were analyzed and compared with regard to postoperative formation of a BNC requiring further therapy. Uni- and multivariable logistic regression analyses (MVAs) were performed to identify possible risk factors for BNC development. RESULTS: We included 1368 patients in this analysis. Out of these, 88 patients (6.4%) developed BNC requiring further surgical therapy. The following factors showed a statistically significant association with BNC development: smaller preoperative prostate volume (p = 0.001), lower resected prostate weight (p = 0.004), lower preoperative levels of prostate-specific antigen (PSA, p < 0.001), shorter duration of the surgery (p = 0.027), secondary transurethral intervention (due to urinary retention or gross hematuria) during inpatient stay (p = 0.018), positive (≥100 CFU/mL) preoperative urine culture (p = 0.010), and urethral stricture (US) formation requiring direct visual internal urethrotomy (DVIU) postoperatively after TURP (p < 0.001), in particular membranous (p = 0.046) and bulbar (p < 0.001) strictures. Preoperative antibiotic treatment showed a protective effect (p = 0.042). Histopathological findings of prostate cancer (PCA) in the resected prostate tissue were more frequent among patients who did not develop BNC (p = 0.049). On MVA, smaller preoperative prostate volume (p = 0.046), positive preoperative urine culture (p = 0.021), and US requiring DVIU after TURP (p < 0.001) were identified as independent predictors for BNC development. CONCLUSION: BNC is a relevant long-term complication after TURP. In particular, patients with a smaller prostate should be thoroughly informed about this complication.

RESUMO

PURPOSE: For male cancer survivors, the combination of stress urinary incontinence and recurrent bladder neck contracture presents a management dilemma with poor consensus. Our objective was to assess the impact of artificial urinary sphincter placement on bladder neck contracture recurrence among prostate cancer survivors with stress urinary incontinence and bladder neck contracture. MATERIALS AND METHODS: Men electing artificial urinary sphincter placement at our institution undergo synchronous bladder neck contracture treatment if indicated. An institutional database was queried for men with stress urinary incontinence and ≥1 intervention for bladder neck contracture. Records were divided according to whether an artificial urinary sphincter was ever placed. The impact of artificial urinary sphincter placement on bladder neck contracture recurrence was assessed using a multivariable conditional survival analysis, with survival defined as the recurrence-free interval following bladder neck contracture intervention. The proportional hazards assumption was assessed on the basis of Schoenfeld residuals. RESULTS: The analytic cohort consisted of 118 in the artificial urinary sphincter group and 88 in the non-artificial urinary sphincter group. Patients in both groups underwent a median of 2 (range 1-8) bladder neck contracture interventions over the entire course of their care, encompassing 445 total bladder neck contracture interventions. The artificial urinary sphincter group was on average 2.6 years younger (P = .02) and had a higher pack-year smoking history (P < .01). The presence of an artificial urinary sphincter was associated with a 61% lower bladder neck contracture re-intervention rate (HR 0.39, P < .01, CI 0.30-0.50) at any time when accounting for number of prior bladder neck contracture interventions and bladder neck contracture risk factors. CONCLUSIONS: Artificial urinary sphincter placement is associated with a lower rate of bladder neck contracture re-intervention. Artificial urinary sphincter placement should not be delayed or avoided due to the presence of bladder neck contracture.

RESUMO

OBJECTIVE: This study aimed to assess the efficacy of single and repeat transurethral bladder neck incision (TUI-BN) for female voiding dysfunction caused by bladder outlet obstruction (BNO). Further, the predictive factors associated with better treatment outcomes were identified. METHODS: Women with voiding difficulty due to BNO who underwent TUI-BN were included in this research. All patients underwent videourodynamics study at baseline and after TUI-BN. Successful outcome was defined as a voiding efficiency of ≥ 66.7% and a global response assessment score of ≥ 2 after treatment. Repeat TUI-BN was considered for patients with insufficient improvement. The outcomes of repeat surgery, surgical complications, and predictive factors of successful outcomes were evaluated. RESULTS: In total 158 cases, the success rates were 61.4% and 45.2% after the first and second TUI-BN, respectively, with an overall cumulative rate of 70.3%. The success rates were comparable between patients with detrusor underactivity (DU) and those without (54.9% vs. 68.4%). The absence of a previous history of suburethral sling and a high baseline corrected maximum flow rate were a significant predictor of favorable outcomes. The cumulative rate of regaining self-voiding function was 95.1%. The incidence rates of vesico-vaginal fistula and de novo stress urinary incontinence requiring surgery were 1.2% and 2.5%, respectively. CONCLUSIONS: Regardless of the presence of DU, TUI-BN is effective against female voiding dysfunction caused by BNO. Repeat procedures are beneficial and can improve self-voiding function. A high corrected maximum flow rate and the absence of a previous history of suburethral sling can contribute to greater success rates.

RESUMO

PURPOSE: To investigate the prevalence of bladder neck incompetence (BNI) and the anatomic differences between different types of urinary incontinence (UI) and overactive bladder (OAB) by transrectal sonography, and to investigate these differences among those with stress UI (SUI) or mixed UI (MUI) who exhibited de novo or persistent OAB symptoms following anti-incontinence surgery. METHODS: A retrospective analysis was conducted on a total of 184 patients with SUI, MUI, urge UI (UUI), or OAB dry who underwent transrectal ultrasound between 2017 and 2022. The presence of BNI and urethral incompetence assessed by transrectal ultrasound were recorded in all included patients, and recorded preoperatively and postoperatively among patients with SUI and MUI who underwent anti-incontinence surgery. RESULTS: Among the patients, 91%, 84%, 76%, and 71% exhibited BNI in MUI, SUI, UUI, OAB dry group, respectively. Significantly higher rate of patients with BNI were found in MUI than in OAB dry group. Patients with OAB symptoms after anti-incontinence surgery exhibited significantly higher rates of BNI and urethral incompetence than those who did not have postoperative OAB symptoms. Among MUI patients with preoperative BNI, significantly lower rate of postoperative BNI and urethral incompetence was observed in individuals who had improved OAB symptoms after surgery, compared to those without improvement. CONCLUSION: A higher BNI rate was observed in the MUI group. A significantly higher BNI rate was observed in women with OAB symptoms after anti-incontinence surgery. Patients with MUI had improved OAB symptoms if BNI was successfully corrected after anti-incontinence surgery.

RESUMO

OBJECTIVE: Functional and anatomic bladder outlet obstruction (BOO) in women are more prevalent than previously suspected and remain a diagnostic challenge. Several urodynamic diagnostic criteria for female BOO have been proposed, but studies validating the criteria by assessing treatment outcomes are lacking. We sought to correlate video urodynamic (VUD) diagnostic criteria with symptom improvement in women with functional bladder outlet obstruction. METHODS: A retrospective cohort study of women diagnosed with primary bladder neck obstruction (PBNO) by VUD criteria who underwent bladder neck incision (BNI) between 2010 and 2022 was performed. Patient demographic, clinical, and urodynamic characteristics were collected before and after treatment and analyzed. RESULTS: Twenty-six women with mean age 64.7 years underwent BNI. Nineteen patients (73.1%) were cured, four (15.4%) improved, and three (11.5%) failed. After BNI the mean postoperative Qmax was significantly higher (9.4 vs. 3 mL/s, p = 0.006) and mean postvoid residual (PVR) was significantly lower (102 vs. 514 mL, p ≤ 0.001). Patients who did not require a catheter preoperatively were more likely to be cured than those who did (90% vs. 62.5%, p = 0.03). The PdetQmax of patients that were cured or improved did not differ significantly from those who were not (50.7 cm H2 O vs. 32 cm H2 O, p = 0.21). CONCLUSIONS: The diagnosis of PBNO by VUD criteria for obstruction correlated with treatment outcomes with success in 88.5% and 56% becoming catheter independent. Successful treatment was independent of preoperative PdetQmax.

RESUMO

INTRODUCTION: The prevalence, formal definition, and diagnostic criteria of bladder outlet obstruction in owmen have not been clearly defined. METHODS: This is a literature review of the definition of BOO in women, its prevalence, as well as its differential diagnosis. RESULTS: The main causes of BOO in women are divided into functional and anatomic conditions. Functional etiologies include detrusor external sphincter dyssynergia, dysfunctional voiding, Fowler's syndrome, and primary bladder neck obstruction. Anatomic causes can be further divided into extrinsinc and intrinsic conditions. Intrinsic etiologies include urethral stricture and urethral diverticula, whereas extrinsic causes comprise pelvic organ prolapse, post anti-incontinence surgery, and Skene's gland cyst or abscess. CONCLUSIONS: There are multiple etiologies to BOO in women, and this condition is most probably underdiagnosed, owing to a lack of consensus for a standard definition.

RESUMO

BACKGROUND: To investigate whether subgroups of prostate cancer patients, stratified by positive surgical margin locations, have different oncological outcomes following robot-assisted radical prostatectomy. METHODS: A retrospective multicenter cohort study in prostate cancer patients undergoing robot-assisted radical prostatectomy was conducted at 10 institutions in Japan. Pre- and post-operative outcomes were collected from enrolled patients. Biochemical recurrence and clinical and pathological variables were evaluated among subgroups with different positive surgical margin locations. RESULTS: A total of 3195 patients enrolled in this study. Data from 2667 patients (70.1% [N = 1869] with negative surgical margins and 29.9% [N = 798] with positive surgical margins based on robot-assisted radical prostatectomy specimens) were analyzed. The median follow-up period was 25.0 months. The numbers of patients with apex-only, middle-only, bladder-neck-only, seminal-vesicle-only and multifocal positive surgical margins were 401, 175, 159, 31 and 32, respectively. In the multivariate analysis, PSA level at surgery, pathological Gleason score based on robot-assisted radical prostatectomy specimens, pathological T stage, pathological N stage and surgical margin status were independent risk factors significantly associated with biochemical recurrence-free survival. Patients undergoing robot-assisted radical prostatectomy with multifocal positive surgical margins and seminal-vesicle-only positive surgical margins were associated with worse biochemical recurrence-free survival than those with apex-only, middle-only and bladder-neck-only positive surgical margins. Patients undergoing robot-assisted radical prostatectomy with apex-only positive surgical margins, the most frequent positive surgical margin location, were associated with more favorable biochemical recurrence-free survival that those with middle-only and bladder-neck-only positive surgical margins. The study limitations included the lack of central pathological specimen evaluation. CONCLUSIONS: Although positive surgical margin at any locations is a biochemical recurrence risk factor after robot-assisted radical prostatectomy, positive surgical margin location status should be considered to accurately stratify the biochemical recurrence risk after robot-assisted radical prostatectomy.

RESUMO

INTRODUCTION AND HYPOTHESIS: Urogynecology fellows report low exposure to nonsling retropubic anti-incontinence procedures such as Burch urethropexy and thus may have difficulty meeting the required minimum case numbers, but there has been an even more objective exploration of this observation. Thus, our objective was to assess the feasibility of meeting the Accreditation Council for Graduate Medical Education (ACGME) requirement for each urogynecology fellow to perform five nonsling retropubic anti-incontinence procedures during fellowship. METHODS: Cross-sectional study using the National Surgical Quality Improvement Program (NSQIP) and National Resident Matching Program (NRMP) databases from 2009 to 2019. From NSQIP, the number of nonsling retropubic anti-incontinence procedures (open and laparoscopic Burch urethropexy and bladder neck needle suspension) and midurethral sling procedures was extracted using CPT codes. The number of fellows was extracted from the NRMP database. Trends in the number of anti-incontinence procedures were compared with the trend in the number of fellows using linear regression. RESULTS: From 2009 to 2019 the number of fellows doubled from 81 to 176. An average of 97 nonsling retropubic anti-incontinence and 6,372 sling procedures were performed annually. Linear regression showed an increase of 10.7 fellows per year (95% CI 9.3-12.1) versus an increase of 5.8 nonsling retropubic anti-incontinence procedures per year (95% CI -0.4 to 12.1). This contrasts with an increase of 690.9 slings per year (95% CI 509.9-872.0). CONCLUSIONS: The increase in the number of nonsling retropubic anti-incontinence procedures does not appear to match the increase in the number of urogynecology fellows. Supplementary educational approaches such as simulation may be prudent.
