RESUMEN
BACKGROUND: Persistent genital arousal disorder (PGAD) is a rare life-altering condition characterized by unwanted, uncomfortable genital sensations or spontaneous orgasms without physical or emotional stimulation. Its etiology remains unclear, and a variety of treatments have been attempted with incomplete resolution. We propose that chronic pudendal neuromodulation (CPN) may be a useful treatment for PGAD symptoms. METHODS: A retrospective chart review was performed for women older than 18 years with a diagnosis of PGAD that had staged neuromodulation with placement of a tined lead at the pudendal nerve. Demographic, operative, and postoperative data were collected. A survey was then sent to these women to assess additional demographic data, preoperative and postoperative symptoms, and patient satisfaction. Descriptive statistics were performed. RESULTS: Six women underwent CPN for PGAD. Mean age was 52 (SD, 9) years. Five (83%) of 6 were still implanted at time of survey, at a mean of 38 months after implantation; 1 device was removed for nonuse. Four of 6 completed surveys and were still using their device. Three of 4 had met their treatment goals and were satisfied with CPN; 3 of 4 felt CPN was the most useful treatment modality they had used overall. Chronic pudendal neuromodulation also improved chronic pelvic pain (4/4), bowel function (3/4), and bladder function (3/4). CONCLUSIONS: Chronic pudendal neuromodulation can be an effective treatment for decreasing frequency of PGAD symptoms and providing symptom relief.

OBJECTIVES: This study aimed to assess the efficacy, efficiency, and costs of 2 methods of trial of void (TOV) after midurethral sling (MUS) placement. METHODS: A retrospective chart review was performed on women who underwent outpatient MUS between January 2013 and April 2014 by 3 urologists. Patients were excluded if they had a concomitant prolapse repair, hysterectomy, bladder/urethral injury, or any procedure that may prolong recovery room (RR) stay. Trial of void was performed by either (1) bladder instillation, catheter removal in the operating room (OR) fill with attempted void in RR, or (2) bladder instillation and catheter removal with immediate attempted void in the RR fill. Intraoperative, postoperative, and cost data were analyzed. RESULTS: Ninety-one of 183 women (mean age, 55.9 ± 12 years; mean body mass index, 28.8 ± 5.8 kg/m) met inclusion criteria. Eighty-three had a transobturator sling. Forty-nine (54%) had an OR fill and 42 (46%) had an RR fill; age and body mass index were similar between groups. The OR fill group had shorter median operative time (15 vs 22 minutes; P = 0.003) and median RR time (138 vs 161, P = 0.033). The OR fill and RR fill groups did not differ in TOV failure rate (3/49 vs 6/42; P = 0.29), overall mean LOS (4.96 vs 5.51 hours; P = 0.055), and median RR costs ($627 vs $678; P = 0.065). No patient had urinary retention after successful TOV. CONCLUSIONS: After MUS placement, both OR fill and RR fill TOV methods are effective and efficient with similar TOV failure rates.

INTRODUCTION: Studies investigating the regional impact of the 2012 U.S. Preventive Services Task Force (USPSTF) recommendation against the use of prostate specific antigen (PSA) screening for prostate cancer have been limited. METHODS: A retrospective cohort study was conducted on men age 50years and older in Southeastern Michigan pre (n=3647) and post (n=3618) USPSTF recommendation. PSA screening, transrectal ultrasound, and prostate biopsy rates were evaluated pre/post using a generalized piecewise linear model with a Poisson distribution, and log link. A knot was placed at year 2011 to estimate pre/post slope coefficients. Generalized estimating equations were used to estimate the marginal probability of a prostate diagnosis as a logistic function of pre and post-period, and comorbidities. RESULTS: PSA utilization significantly increased (ß=0.28; 95% CI: 0.25, 0.31) during the pre-period, but significantly decreased in the post-period (ß=-0.29; 95% CI: -0.34, -0.25). Prostate biopsies decreased pre (ß=-0.16; 95% CI: -0.25, -0.08) and did not change post (ß=0.01; 95% CI: -0.09, 0.12). Transrectal ultrasounds were stable pre (ß=0.16; 95% CI: -0.03, 0.35) and significantly decreased post (ß=-0.27; 95% CI: -0.50, -0.04). Patients in the post-period had a decreased probability of having a diagnosis of prostate cancer (OR: 0.81; 95% CI: 0.74-0.89) compared to the pre-period. CONCLUSION: Our study demonstrates how PSA tests are still being frequently used in Southeastern Michigan. Further research is needed to better understand regional variation in prostate cancer screening practices in the U.S.

INTRODUCTION: To evaluate the efficacy of transecting anastomotic urethroplasty (AU) and buccal mucosa graft (BMG) ventral onlay substitution urethroplasty (SU) in treating short bulbar urethral strictures. MATERIALS AND METHODS: Sixty patients underwent either AU or SU for bulbar strictures of similar length with follow up of at least 12 months. Follow up included clinical history, uroflowmetry, and ultrasound post-void residuals (PVR) performed every 4 months for the first year and yearly thereafter. RESULTS: Out of 131 patients with short bulbar strictures, 40 were treated with BMG onlay SU and 20 had AU. Median follow up in the SU group was 57 months (IQR 27-76) and 120 months (IQR 109-130) in the AU group. The median stricture length was 3 cm (IQR 2.5-3.0) in the SU group and 1.3 cm (IQR 1-2) in the AU group (p < 0.001). The 3 year freedom from intervention was 93% in the SU group, and 85% in the AU group (p = 0.72). CONCLUSIONS: BMG onlay ventral urethroplasty has similar success rates to anastomotic urethroplasty for short bulbar urethral strictures. Due to the relatively fewer complications reported after substitution urethroplasty with BMG, it should be considered the treatment of choice for short bulbar urethral strictures.

INTRODUCTION: Several clinical series of retrograde nephrostomy for percutaneous nephrolithotomy (PCNL) have been published over the past 30 years demonstrating good outcomes and safety. We previously reported our adaptation of the Lawson technique, wherein we deploy the puncture wire through a flexible ureteroscope. We herein aim to clarify the performance characteristics of this nephrostomy creation technique. MATERIALS AND METHODS: Institutional Review Board approval and informed consent were obtained. A ureteroscopy-assisted retrograde nephrostomy (UARN) procedure was performed as described previously. Data were collected prospectively. Multiple patient and operative factors were evaluated for association with UARN success and nephrostomy creation time: body mass index (BMI), skin-to-stone distance, Guy's score, Clinical Research of the Endourological Society nephrolithometric score, hydronephrosis, stone burden, location of nephrostomy, exit from a stone-bearing calix, and use of holmium laser to access calix. RESULTS: Nephrostomy was successful in 49/52 UARN procedures (94%). Only single access was placed: upper-18, mid-27, and lower-7. Median BMI was 29 kg/m(2) and median time for nephrostomy creation was 39 minutes. Fluoroscopy time for the entire PCNL including nephrostomy creation was 84 and 16 seconds for case numbers 1-25 and 26-52, respectively. By stepwise linear regression, variables correlating with nephrostomy creation time were BMI (r(2)=0.219), stone burden (r(2)=0.094), use of holmium laser to access calix (r(2)=0.104), and total r(2) linear=0.416. CONCLUSIONS: UARN is an intuitive safe procedure that offers dramatic reductions in fluoroscopy times. UARN is best suited to cases requiring only one nephrostomy tract. Upper pole access is commonly performed with a subcostal technique to navigate the puncture wire below the ribs. Increasing BMI best predicts longer nephrostomy creation times; procedure failure was associated with BMI exceeding 40 kg/m(2). UARN is a robust technique for nephrostomy creation in appropriately selected patients.

OBJECTIVE: To compare the outcomes of active surveillance (AS) series between African American men (AAM) and non-AAM diagnosed with low-risk prostate cancer at 3 medical centers. METHODS: Between 2005 and 2012, 214 men accepted AS on the basis of favorable clinical features and parameters after initial and repeat biopsy. Failure was defined as increase in Gleason score >6, total positive cores >33%, maximum cancer volume in any core >50%, or a prostate-specific antigen >10 ng/mL. Disease progression and overall AS failure were compared between the 2 groups. RESULTS: Of 214 men, 75 were excluded, leaving 67 AAM and 72 non-AAM on AS. Median age at diagnosis was 64 and 67 years for AAM and non-AAM, respectively, and median follow-up was 34 and 46 months, respectively. During this time, 44 AAM (66%) remained on AS, and 23 (34%) underwent treatment, of whom 6 (26%) were treated by patient choice and 17 (74%) because of disease progression. In the non-AAM group, 59 (82%) men remained on AS, and 13 (18%) underwent treatment, 8 (62%) were treated by patient choice and 5 (38%) because of disease progression. The 3-year freedom from overall treatment was 74% and did not differ by race (P = .06). The 3-year freedom from disease progression was 85%, where AAM were at significantly higher risk of disease progression (hazard ratio = 3.8; 95% confidence interval: 1.4-10.4; P = .01). CONCLUSION: Our study suggests a higher disease progression rate in AAM who choose AS for low-risk prostate cancer compared with non-AAM, signifying a potential need for closer follow-up and more stringent enrollment criteria in AAM.

OBJECTIVE: To evaluate the efficacy of augmenting ventral onlay buccal urethroplasty using a using a double-sided graft technique by adding a second, full-thickness skin graft (FTSG) dorsally in long strictures ≥4 cm, we hypothesized that a double-sided graft technique would improve surgical outcomes over buccal mucosal graft (BMG) ventral onlay urethroplasty alone. METHODS: Retrospective chart review was performed comparing 15 patients who had undergone double-sided BMG + FTSG urethroplasty for long strictures ≥4 cm to a cohort group of 115 patients who had undergone BMG onlay urethroplasty for strictures of similar length. Comparisons of age, stricture lengths, time-to-failure, follow-up intervals, and failure rates were analyzed. Further analysis included age and stricture length matched control comparisons between BMG + FTSG patients to BMG only patients. RESULTS: Mean patient age, stricture length, and time to stricture recurrence were 44 years, 5.1 cm, and 10 months, respectively, in the BMG group. For the BMG + FTSG group, mean age was 52 years, stricture length 5.9 cm, and time to recurrence was 9 months. Overall, the BMG group had a decreased failure rate; 17% compared to 21%. Further analysis showed BMG ventral onlay had decreased failure rates for strictures <6 cm; 16% compared to 33%. However, for strictures ≥6 cm, the BMG + FTSG had a 0% failure rate compared to 24% in the BMG ventral onlay group (P = .005). CONCLUSION: Combined BMG and FTSG urethroplasty for very long bulbar urethral strictures ≥6 cm improve success rates compared to using BMG urethroplasty alone.
