Extravesical robotic ureteral reimplantation for ureterovaginal fistula.

INTRODUCTION

We present a video describing the technical considerations for performing an extravesical robotic ureteral reimplantation.

METHODS

A 55-year old woman presented with urinary incontinence secondary to a ureterovaginal fistula after robotic-assisted hysterectomy. After failure of more conservative measures, she proceeded to a robotic ureteral reimplantation. Following port placement, the ureter is identified at the level of the iliac vessels and dissected circumferentially. The ureter is dissected free to the level of the ureterovaginal fistula, transected, and the distal remnant ligated. The ureter is spatulated, a cystotomy created, and a running anastomosis with mucosa-to-mucosa apposition performed over a stent. Care is taken to ensure it is tension free. The integrity of the anastomosis is tested with retrograde filling of the bladder. Postoperatively, a drainage catheter is left to allow for adequate healing. Follow-up imaging is performed to ensure a patent anastomosis.

RESULTS

The patient had an uncomplicated postoperative course. A cystogram showed adequate healing at 10 days, and the stent was removed at 6 weeks. A follow-up renal ultrasound 6 weeks later showed no hydronephrosis.

CONCLUSIONS

Extravesical robotic ureteral reimplantation is a useful technique for managing ureterovaginal fistula; here we highlight pertinent technical considerations.
