- To develop and validate a clinical classification system for urethral stricture disease (USD) based on the retrograde urethrogram (RUG), physical exam, and stricture-specific patient history.
- To analyze contemporary urethroplasty trends and urethral stricture etiologies over a 7-year study period among urologists from a large multi-institutional surgical outcomes group.
- To review a robotic approach to recalcitrant bladder neck obstruction and to assess success and incontinence rates.
- To evaluate the success of urethroplasty for urethral strictures arising after erosion of an artificial urinary sphincter (AUS) and rates of subsequent AUS replacement.
- To determine if age is an independent predictor of surgical success in patients undergoing urethroplasty. Urethroplasty performed by excision and primary anastomosis depends on vascular collateralization. Successful augmented urethroplasty depends on graft neovascularization. Older patients have more comorbid conditions including peripheral vascular disease associated with reduced penile blood flow.
