Sexual function following pelvic fracture urethral injury and posterior urethroplasty.

BACKGROUND: To evaluate erectile and sexual function after pelvic fracture urethral injury (PFUI) by performing a retrospective review of a large multi-center database. We hypothesized that most men will have erectile dysfunction (ED) and poor sexual function following PFUI, which will remain after posterior urethroplasty. METHODS: Using the Trauma and Urologic Reconstructive Networks of Surgeons (TURNS) database, we identified PFUI patients undergoing posterior urethroplasty. We excluded patients with incomplete demographic, surgical and/or questionnaire data. Sexual Health Inventory of Men (SHIM), Male Sexual Health Questionnaire (MSHQ), and subjective changes in penile curvature were collected before urethroplasty surgery and at follow-up. We performed descriptive statistics for erectile and ejaculatory function using STATA v12. RESULTS: We identified 92 men meeting inclusion criteria; median age was 41.7 years and BMI was 26.5. The mechanism of injury was blunt in all patients, and average distraction defect length was 2.3 cm (SD 1.0 cm). In the 38 patients who completed both pre and post-operative SHIM questionnaires, the mean SHIM score was 10.5 (SD 7.0), with 63% having severe ED (SHIM <12). The median follow-up was 5.6 months and the mean post-operative SHIM was 9.3 (SD 6.5), with 68% having severe ED. The mean change in SHIM score was -1.18 (SD 6.29) with 6 (16%) patients reporting de novo ED (≥5 point decrease in score). Of the men with pre-operative MSHQ data, 46/74 (62.1%) had difficulty with ejaculation, 25/35 (71%) had change in penile length, and 6/33 (18%) reported penile curvature. In men with post-operative MSHQ, 19/44 (43%) expressed difficulty with ejaculation, 23/32 (72%) had change in penile length, and 9/33 (27%) reported penile curvature. CONCLUSIONS: There is a high rate of severe ED, both following PFUI and remaining after posterior urethroplasty. Additionally, rates of ejaculatory difficulty and patient perceived changes in penile length and curvature underscore the complex nature of the impact of these injuries on sexual function beyond simple erectile function.

Endoscopic Management of Iatrogenic Ureteral Injury: A Case Report and Review of the Literature.

Background: Iatrogenic ureteral injury represents an uncommon, but significant, complication of gynecologic surgery. Endoscopy has typically played little to no role in the treatment of these injuries, which are traditionally managed with re-exploration or delayed repair. Delayed repair with temporary urinary diversion exposes the patient to significant morbidity. We present a case in which iatrogenic ureteral injury is managed definitively with endoscopy alone. Case Presentation: We present a 32-year-old female who developed a delayed postpartum hemorrhage following cesarean section, necessitating emergent hysterectomy. Postoperatively, there was concern for right ureteral injury. A computed tomography (CT) urogram was obtained showing right-sided hydronephrosis, but no obvious ureteral injury. After developing right flank pain, the patient was taken to the operating room for further evaluation. On semirigid ureteroscopy, a suture was identified within the lumen of the ureter and incised with the holmium laser, effectively treating the obstruction. At a 10-week follow-up, a renal ultrasound showed no hydronephrosis. At 8 months, the patient reports she is doing well with no flank pain. Conclusion: We present, to the best of our knowledge, the first published report in the United States of an iatrogenic ureteral ligation managed effectively in an acute postoperative setting with endoscopic holmium laser release, without balloon dilation, sparing the patient from delayed surgical intervention and the potentially associated morbidity. It is our belief that an initial retrograde pyelogram followed by a ureteroscopic evaluation should be performed as this allows for proper characterization of the injury, and may allow one to attempt definitive endoscopic management.

Radical Cystectomy Compared to Combined Modality Treatment for Muscle-Invasive Bladder Cancer: A Systematic Review and Meta-Analysis.

PURPOSE: To perform a comprehensive comparison of overall survival (OS), disease-specific survival (DSS), progression-free survival (PFS), and treatment-related complications between radical cystectomy (RC) and combined modality treatment (CMT-radiation therapy, concurrent chemotherapy, and maximal transurethral resection of bladder tumor) in the setting of muscle-invasive bladder cancer. METHODS AND MATERIALS: We searched 7 databases (PubMed, Scopus, EMBASE, Proquest, CINAHL, and ClinicalTrials.gov) for randomized, controlled trials and prospective and retrospective studies directly comparing RC with CMT from database inception to March 2016. We conducted meta-analyses evaluating OS, DSS, and PFS with hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: Nineteen studies evaluating 12,380 subjects were selected. For the 8 studies encompassing 9554 subjects eligible for meta-analyses, we found no difference in OS at 5 years (HR 0.96, favoring CMT, 95% CI 0.72-1.29; P=.778) or 10 years (HR 1.02, favoring cystectomy, 95% CI 0.73-1.42; P=.905). No difference was observed in DSS at 5 years (HR 0.83, favoring radiation, 95% CI 0.54-1.28; P=.390) or 10 years (HR 1.17, favoring cystectomy, 95% CI 0.89-1.55; P=.264), or PFS at 10 years (HR 0.85, favoring CMT, 95% CI 0.43-1.67; P=.639). The cystectomy arms had higher rates of early major complications, whereas rates of minor complications were similar between the 2 treatments. CONCLUSION: Current meta-analysis reveals no differences in OS, DSS, or PFS between RC and CMT. Further randomized, controlled trials are necessary to identify the optimal treatment for specific patients.

Central zone lesions on magnetic resonance imaging: Should we be concerned?

INTRODUCTION AND OBJECTIVE: The Prostate Imaging Reporting and Data System (PI-RADS) score was developed to evaluate lesions in the peripheral and transition zone on multiparametric magnetic resonance imaging (mpMRI) of the prostate. We aim to determine if the PI-RADS scoring system can be used to evaluate central zone lesions on mpMRI. MATERIALS AND METHODS: A retrospective review of 73 patients who underwent mpMRI/ultrasound (US) fusion-guided biopsy of 143 suspicious lesions between February 2014 and October 2015 was performed. All patients underwent a 3T mpMRI. Indications for mpMRI included an abnormal digital rectal examination, PSA velocity >0.75ng/dl/y, and patients on active surveillance. The mpMRI sequence involved T2-weighted imaging, diffusion-weighted imaging, and dynamic contrast enhancement. Using 3-dimensional model software (Invivo Corporation, Gainesville, FL, USA), a minimum of 3 magnetic resonance imaging (MRI)/US fusion-guided biopsy samples were taken from each prostate lesion seen on mpMRI irrespective of PI-RADS score, using local anesthesia in an outpatient clinic setting. RESULTS: A total of 73 patients underwent MRI/US fusion-guided biopsy of 85 peripheral zone lesions, 31 transitional zone lesions, and 27 central zone lesions. Only 2 (7%) of central zone lesions were positive for prostate cancer. Both patients had lesions which were graded as PI-RADS 3. Both the patients had multifocal lesions that encompassed≥50% of the central and transition zones on the sagittal view MRI images. Both patients previously had transrectal US-guided biopsy of the prostate which was negative for cancer. Both patients underwent a robotic-assisted laparoscopic prostatectomy, each revealing high-grade cancer. CONCLUSIONS: Lesions involving only the central gland/zone seen on MRI are less concerning for malignancy and should not be given equal weight as peripheral zone lesions. In this series, no lesions involving solely the central gland/zone, regardless of PI-RADS score, was positive for malignancy on MRI/US fusion-guided biopsy. Consideration of a modified PI-RADS scoring system should be given to help identify central zone lesions with malignant potential.
