Management of Urethral Stricture in Women

PURPOSE We describe the diagnosis and treatment of urethral strictures in women. MATERIALS AND METHODS We retrospectively identified female urethral strictures from 1998 to 2010. Study inclusion criteria were 1) clinical diagnosis of stricture, 2) stricture seen on cystoscopy, 3) urethral obstruction on videourodynamics according to the Blaivas-Groutz nomogram and/or 4) urethral caliber less than 17Fr. Postoperative recurrence was defined by the preoperative criteria. RESULTS We identified 17 women with a mean age of 62 years (range 32 to 91) with stricture. Stricture was idiopathic in 8 patients, iatrogenic in 6, traumatic in 2 and associated with a urethral diverticulum in 1. Videourodynamics could not be done in 3 women due to complete obliteration of the urethra. Ten of 14 patients satisfied videourodynamic criteria for obstruction and 4 had impaired detrusor contractility. Nine women underwent vaginal flap urethroplasty, including 5 who also had a pubovaginal sling and 1 who had a Martius flap. One patient received a buccal mucosal graft as primary treatment after initial dilation. There was no recurrence at a minimum 1-year followup but 2 strictures recurred 5½ and 6 years postoperatively, respectively. These 2 women received a buccal mucosal graft and were stricture free 12 to 15 months postoperatively. Of 17 patients initially treated with urethral dilation recurrence developed in 16, requiring repeat dilations until urethroplasty was performed. CONCLUSIONS In select women vaginal flap urethroplasty and buccal mucosal graft have high success rates, including 100% at 1 year and 78% at 5 years. Urethral dilation has a 6% success rate. Long-term followup is mandatory. Treatment should be individualized.

The Association Between Operative Repair of Bladder Injury and Improved Survival: Results From the National Trauma Data Bank

PURPOSE The bladder is the most commonly injured genitourinary organ from blunt pelvic trauma. In this study we describe traumatic bladder injuries in the United States, their management and association with mortality. MATERIALS AND METHODS We queried the 2002 to 2006 National Trauma Data Bank for all subjects with bladder injury. Demographics, mechanism of injury, coexisting injuries, type of bladder injury, and operative interventions for bladder and other abdominal trauma are described. Multivariate logistic regression analysis was used to examine the relationship between bladder injury and in-hospital mortality. RESULTS Of 8,565 subjects with bladder trauma 46% had pelvic fracture and 15% had 2 or more intra-abdominal injuries. Of these subjects 54% underwent bladder surgery, including 76% with intraperitoneal injury and 51% with surgical repair of other abdominal organs. On multivariate analysis operative bladder repair reduced the likelihood of in-hospital mortality by 59%. Greater likelihood of death was seen in African-American and Native American patients, and those with pelvic injuries, triage to higher acuity care, penetrating trauma and multiple abdominal injuries. CONCLUSIONS We demonstrated that surgical repair provides a significant survival advantage for subjects with bladder trauma. With 76% of intraperitoneal bladder injuries being repaired, there appears to be underuse of a lifesaving procedure. Additional studies to refine indications for bladder repair are warranted.

Cost-effectiveness of neoadjuvant chemotherapy before radical cystectomy for muscle-invasive bladder cancer

OBJECTIVES To determine the costs of treatment and the duration of survival, adjusted for quality of life, for patients with muscle-invasive bladder cancer treated with immediate radical cystectomy (RC) or with neoadjuvant chemotherapy (NAC) with intent for subsequent RC. METHODS AND MATERIALS A retrospective review of our institutional review board-approved database identified patients with muscle-invasive bladder cancer treated at our institution from 2004 to 2011. Patients were divided into those receiving RC alone and those receiving NAC before planned RC. Patients who refused RC following NAC were included in an intention-to-treat analysis. Survival duration was converted to quality-adjusted life years (QALYs), and costs of treatment per QALY were determined. RESULTS A total of 119 patients (65.4%) received RC alone and 63 (34.6%) received NAC, 38 of whom proceeded to cystectomy as planned. Mean total costs were

The 5-year overall survival measured in QALYs was 21.9% and 42.9% for the RC-only and the NAC groups, respectively (P = 0.021). The increased cost for NAC was
