To evaluate the success of urethroplasty for urethral strictures arising after erosion of an artificial urinary sphincter (AUS) and rates of subsequent AUS replacement.From 2009-2016, we identified patients from the Trauma and Urologic Reconstruction Network of Surgeons and several other centers. We included patients with urethral strictures arising from AUS erosion undergoing urethroplasty with or...
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...
To validate the use of the International Prostate Symptom Score (IPSS) as a stand-alone tool to detect urethral stricture recurrence following urethroplasty.This study included 393 men who had undergone anterior urethroplasty and were enrolled in a multi-institutional outcomes study. Data analyzed included pre- and post-operative answers to the IPSS in addition to findings from a same- day cystoscopy...
To evaluate the short- to medium-term outcomes after artificial urinary sphincter (AUS) placement from a large, multi-institutional, prospective, follow-up study. We hypothesize that along with radiation, patients with any history of a direct surgery to the urethra will have higher rates of eventual AUS explantation for erosion and/or infection.A prospective outcome analysis was performed on 386 patients...
To evaluate multi-institutional outcomes of bulbar urethroplasty utilizing a standardized cystoscopic follow-up protocol.Eight reconstructive surgeons prospectively enrolled urethral stricture patients in a multi-institutional study and performed postoperative cystoscopy at 3 and 12 months. Anatomic failure was defined as the inability to pass a flexible cystoscope without force. Functional failure...
To analyze the practice patterns of recently fellowship-trained reconstructive urologists to help guide fellowship program curriculum development and to evaluate the impact that formal reconstructive urology training has on academic urology programs. We evaluated the case logs of 7 recently fellowship-trained reconstructive urologists affiliated with US academic institutions from August 2009 to...
To assess whether sympathetic reinnervation of the rat proximal urethra is affected by differences in estrogen levels. Sympathetic innervation mediates tonic contraction of proximal urethral smooth muscle, thus contributing to urinary continence. Urethral innervation is particularly susceptible to damage during vaginal delivery, a time characterized by decreasing estrogen levels.Adult female rats...
Antenatal hydronephrosis is the most common genitourinary pathologic finding during gestational ultrasonography. Congenital midureteral strictures are an unusual cause of prenatal hydronephrosis, with 13 total previously reported and only 1 diagnosed as a result of antenatal ultrasonography.We present 4 cases of midureteral strictures as the cause of antenatal hydronephrosis and review the published...
