Abstract
PURPOSE: We present our initial experience and 9-month outcomes of the novel technique of laparoscopic onlay lingual mucosal graft ureteroplasty for proximal ureteral stricture. MATERIALS AND METHODS: In June 2015, transperitoneal laparoscopic onlay lingual mucosal graft ureteroplasty was performed on a male patient with proximal stricture of the left ureter. The patient complained with left frank pain. Severe hydronephrosis and proximal ureteral dilatation were noted through ultrasonography and CT scan. The length of upper ureteral stricture was 30 mm including 10-mm occlusion. A 46 mm in length and 15 mm in width lingual mucosa graft was harvested from the ventral of the tongue and placed in the strictured ureter as a ventral onlay for laparoscopic ureteroplasty. Operative time, intraoperative, and postoperative complications were well recorded. Follow-up was performed with renal ultrasound, CT scan, and nuclear scan renography as well as clinical assessment of symptoms. RESULTS: The new technique was performed successful without intraoperative and postoperative complications. Neither hydronephrosis nor proximal ureteral dilatation in the left side was found through ultrasonography 3, 6, 9 months and CT scan 6 month postoperatively. The left renal function, glomerular filtration rate, had a recovery from 9.6 ml/min preoperatively to 14.0 ml/min at 6-month follow-up, and the patient has no complaints about the donor site and flank pain. CONCLUSIONS: To our knowledge, we present the initial experience with laparoscopic onlay lingual mucosal graft ureteroplasty for proximal ureteral stricture. With 9-month outcomes, the new technique appears to be an excellent option for proximal ureteral stricture.
