- To demonstrate our hypothesis that the presence of extravasation on postoperative urethrogram is inconsequential for disease recurrence in urethroplasty postoperative follow-up.
- 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.
