Laparoscopic T-Plasty for the Treatment of Refractory Bladder Neck Stenosis

Preliminary results of a case series on refractory bladder neck stenosis treated with laparoscopic T-plasty are presented in this article. This study retrospectively identified nine patients with refractory bladder neck stenosis aged 60 to 80 years between May 2016 and December 2017, who had undergone laparoscopic T-plasty. All patients presented voiding difficulty and failed after two or more prior endoscopic treatments. Laparoscopic T-plasty was performed by incising the anterior wall of the bladder neck in a T-shaped manner and creating two well-vascularized and tension-free flaps, which offer the possibility to reconstruct a wide bladder neck. After a mean follow-up of 14.7 months (ranging 3-22 months), a successful outcome was achieved in eight patients without incontinence secondary to surgery. Recurrent voiding difficulty developed in one patient, which was cured after a following endoscopic treatment. Through these nine patients, a preliminary conclusion can be drawn that a wider bladder neck can be obtained through modified YV-reconstruction of the bladder neck, while avoiding external urethral sphincter injury. And laparoscopic T-plasty has clear advantages compared with an open approach. It is an available and effective option for refractory bladder neck stenosis.
