This study aims to investigate the effect of non-transecting anastomotic urethroplasty for treatment of posterior urethral stricture. A total of 23 patients with traumatic posterior urethral stricture were enrolled and then divided into two groups. In one group, 12 patients underwent non-transecting anastomotic urethroplasty. In the other group, 11 patients underwent conventional posterior urethra end-to-end anastomosis. The effect of operation was evaluated using the following parameters: the bleeding amount during operation, operation time, IIEF-5 scores after operation, maximum flow rate (Qmax), and rating scale of quality of life (QoL)...

AIMS: We validated a Turkish language version of the urethral stricture surgery specific patient-reported outcome measure (USS-PROM) in men undergoing anterior urethroplasty. We also investigated changes in erectile function (EF) and quality of life (QoL) due to oral mucosa graft (OMG) harvesting. METHODS: The USS-PROM captures lower urinary tract symptoms (LUTS), health related QoL (HRQoL) with EQ-5D visual analogue scale (EQ-VAS). To evaluate EF and OMG morbidity, we used International Index of Erectile Function (IIEF-5) and a self-completed questionnaire, respectively...

REVIEW
Bruce J Schlomer
PURPOSE OF REVIEW: The first stage of a 2-stage proximal hypospadias repair involves division of the urethral plate and correction of any residual ventral penile curvature (VPC). Options to correct residual VPC include dorsal corporal shortening or ventral corporal lengthening techniques. This review discusses these options and suggests an approach to management. RECENT FINDINGS: Recent reports of 2-stage proximal hypospadias repairs indicate low rates of recurrent VPC with either dorsal corporal shortening or ventral corporal lengthening...

The surgical treatment of a long proximal ureteral stricture is a challenging situation for reconstructive surgeons. Despite the underlying morbidities, ileal interposition and autotransplantation are the options available to treat complex cases of long segment ureteral stricture. Buccal mucosa has shown excellent results in urethroplasty. However, its use in ureteral reconstruction is infrequent. We report on a 64-year-old female patient with multiple comorbidities and prior abdominal surgeries for Crohn's disease who underwent a successful total substitution of a long segment of the proximal ureter using buccal mucosa...

BACKGROUND: Urethroplasty is often successful for the treatment of male urethral stricture disease, but limited data exists on recurrence management. Our goal was to evaluate direct visual internal urethrotomy (DVIU) as a treatment option for isolated, recurrent strictures after urethroplasty. METHODS: We retrospectively identified male patients who underwent urethroplasty from 1999 to 2013 and developed an isolated, recurrent stricture at the urethroplasty site treated with DVIU...

INTRODUCTION: The main disadvantage of currently described techniques of spongioplasty is superimposition of 3 suture lines (neourethra, spongioplasty, and skin closure) which is likely to increase the chances of a fistula. We describe and evaluate the results of a double breasting spongioplasty in urethroplasty. METHODS: A prospective study of 60 primary hypospadias was undertaken by double breasting spongioplasty from August 2012 to March 2014. Mobilization of the urethral plate and the spongiosum is done by creating a plane just proximal to the meatus...

BACKGROUND: Although staged repair for reconstructing severe hypospadias is more popular, various one-stage repairs have been attempted. Koyanagi repair (parameatal-based and fully extended circumferential foreskin flap urethroplasty) has enabled correction of severe hypospadias in one stage. However, its un-acceptably high incidence of complications has initiated a series of technical modifications, including the "yoke" repair. OBJECTIVES: To retrospectively analyze the outcome of a proposed modification of the originally described yoke repair, for patients with severe hypospadias...
