To describe the technique of robotic buccal mucosa graft ureteroplasty as a minimally invasive alternative method of ureteral reconstruction for proximal or multifocal ureteral strictures not amenable to primary anastomosis.

Between October 2013 and May 2014, we performed robotic-assisted ureteral reconstruction using buccal mucosa grafts in four patients (mean age 41.5, range 23-67). The indication for surgery was a proximal or multifocal stricture not amenable to ureteroureterostomy or ureteropyelostomy. Buccal mucosa grafts were harvested to be the length of the strictured segment and 1 cm in width and placed in the ureter as an anterior or posterior onlay. Follow up was performed with diuretic renogram at least 3 months postoperatively and renal ultrasound as well as clinical assessment of symptoms.

All 4 patients underwent successful robotic-assisted reconstruction of the ureter using buccal mucosa graft. There were no intraoperative complications. At a median follow up of 15.5 months (range 10.7-18.6), there has been 100% success.

Robotic buccal mucosa graft ureteroplasty is a feasible option for reconstruction of proximal or multifocal ureteral strictures that are not amenable to primary anastomosis and it avoids the morbidity of alternative procedures.
