ABSTRACT
OBJECTIVE: To determine the natural history and rate of progression of incidental wide-caliber, anterior urethral strictures (USs) in men using a validated stricture staging system. SUBJECTS AND METHODS: Men with incidental findings of anterior US on cystoscopy performed for urologic conditions other than US were retrospectively reviewed from 2001 through 2016. Diagnosis of US on cystoscopy was made according to a validated staging system: stage 0 = no stricture; stage 1 = wide-caliber stricture; stage 2 = requires gentle dilation with a flexible cystoscope; stage 3 = impassable stricture with a visible lumen; and stage 4 = no visible lumen. Using this staging system, this study assessed the change over time of US in patients found to have a stage 1 stricture. The primary outcome was the US grade at time of follow-up. Secondary outcomes include the need for further intervention. RESULTS: Thirty-two patients with 42 separate strictures were evaluated. Median length of follow-up between first cystoscopy and ultimate cystoscopy was 23 months, with a median of 4 cystoscopies per patient. Of the 42 strictures, 15 regressed to a stage 0 (36%), 22 remained as stage 1 (52%), and 5 (12%) progressed to stage 2. None of the patients required additional intervention. CONCLUSION: The majority of low-stage USs does not progress. This supports the notion that strictures are a graded phenomenon, and not all require surgical intervention.

INTRODUCTION: To develop and validate a lower urinary tract symptom score (LUTSS) as a measure of lower urinary tract symptom (LUTS) severity and a treatment outcome tool in adults. MATERIALS AND METHODS: An expert panel was convened to develop the LUTSS questionnaire. Content validity was achieved by obtaining subject and expert feedback from two prospective drafts. Subjects were divided into three groups: normal, LUTS and overactive bladder (OAB). Questionnaire was administered on two separate occasions within 1-2 weeks. Test-retest reliability, internal consistency, discriminant validity, criterion validity and responsiveness to change were also assessed. RESULTS: The questionnaire contains 14 questions with answers scored on a 5-point Likert scale (0-4). It includes 9 storage, 4 voiding and 1 bother question. One hundred ninety-one patients completed it; 80 males and 111 females, mean age 65 years (range 22-91). Seventy-two had OAB, 91 LUTS without OAB and 28 were normal. Test-retest intraclass correlation was 0.96 and Cronbach's-â¡ was 0.77, indicating strong test-retest reliability and internal consistency, respectively. ANOVA and post-hoc bootstrap-generated adjustments showed significant differences between the three groups (p < 0.001), demonstrating discriminant validity. Responsiveness to change was exhibited by the significant decrease between preop and postop scores and a concurrent patient global impression of improvement (PGI-I) score indicative of symptomatic improvement. CONCLUSION: The 14-question LUTSS is a validated questionnaire that assesses a full range of LUTS in men and women. The ordinal nature of the data with its highly specific description of symptoms makes it ideally suited as a nuanced and comprehensive symptom score and patient reported outcome (PRO) tool.

Implantation of a synthetic midurethral sling (SMUS) is the most commonly performed anti-incontinence operation in women worldwide. The effectiveness of the SMUS is comparable to that of the historical gold standards--autologous fascial slings and the Burch colposuspension. Much controversy, however, has evolved regarding the safety of this type of sling. Overall, the quality of the studies with respect to assessing risks of SMUS-associated complications is currently poor. The most common risks in patients with SMUS include urethral obstruction requiring surgery (2.3% of patients with SMUS), vaginal, bladder and/or urethral erosion requiring surgery (1.8%) and refractory chronic pain (4.1%); these data likely represent the minimum risks. In addition, the failure rate of SMUS implantation surgery is probably at least 5% in patients with stress urinary incontinence (SUI). Furthermore, at least one-third of patients undergoing sling excision surgery develop recurrent SUI. Considering the additional risks of refractory overactive bladder, fistulas and bowel perforations, among others, the overall risk of a negative outcome after SMUS implantation surgery is ≥15%.
