Reparación totalmente laparoscópica de megauréter obstructivo primario con pieloplastia, preparación escisional completa y reimplante ureteral sin reflujo

Objective To describe a new surgical technique of the first case of totally laparoscopic repair of primary obstructive congenital megaureter with pyeloplasty, intracorporeal excisional tailoring of the ureter and nonrefluxing ureteroneocystostomy. Methods A 15-year-old male presented with obstructive megaureter. The standard three-port transperitoneal pyeloplasty technique and an additional 5-mm port for dynamic traction were used. Pelvic and ureteral dissection, pyeloplasty, intracorporeal excisional ureteral tailoring and nonrefluxing ureteroneocystostomy were all completed laparoscopically. A double-J stent was used to calibrate the ureter. Results Operative time was 240 min. No intra and postoperative complications were observed, and there was discharge on postoperative day 2. The patient was pain-free and without urinary tract infection during the 4-month period after surgery. Follow up revealed complete resolution of the ureteral obstruction and adequate pelvic and ureteral caliber. Conclusion Laparoscopic pyeloplasty, intracorporeal excisional tailoring, and non-refluxing reimplantation are safe and effective for the treatment of obstructive congenital megaureter. The totally laparoscopic approach is reproducible and provides low morbidity with inherent cosmetic advantages.
