The bulbar urethra is the most common site of stricture disease for which urethroplasty remains standard of care. A decrease in trauma as an etiology in the developed world and concerns regarding sexual dysfunction related to transection of the corpus spongiosum have placed a renewed emphasis on non-transecting urethroplasty techniques. Here, we present our surgical algorithm with emphasis on non-transecting techniques for bulbar urethral stricture disease and review the current state of literature comparing transecting to non-transecting approaches in order to provide guidance to practitioners on patient selection, counseling, and technique.
cortical function and obstruction to outflow at UPJ. With the given history and evaluation, patient was diagnosed to have Bilateral UPJO and planned for bilateral robot-assisted pyeloplasty. Intraoperatively, on the left side, at pyelotomy the ureter seemed dilated across UPJ raising questions over pre-operative diagnosis. Consequently distal patency check was undertaken to confirm the site of obstruction. After gentle distal ureteric dissection, extrinsic compression at the site of crossing left testicular vein was found to be the site of actual ureteric obstruction. To relieve this compression, the ureter was super positioned over a posteriorized gonadal vein with a subsequently successful distal patency check. Taking lessons from the left side, we started with distal ureteric dissection and surprisingly found extrinsic compression with right testicular vein on the right side as well. Site of compression was visualised as fibrosed ureteric segment which was excised and ureteroureterostomy was done super positioned over a posteriorized right gonadal vein.RESULTS: The patient had an uneventful post-operative course and bilateral double-J stents were removed at 3 weeks. Follow-up renogram at 3 months documented the resolving bilateral hydronephrosis and unobstructed drainage.CONCLUSIONS: Lessons learned from the given case are-Contrast-enhanced CT imaging could have suggested ureteric compression with gonadal vein pre-operatively, Distal patency check is vital when there is dilatation across PUJ, When in doubt, distal ureteric dissection is a better approach and preservation of ureteric vascularity is of paramount importance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
