Abstract: This paper focuses on a novel modified technique about the treatment of adult obstructed megaureter by the transperitoneal laparoscopic procedure. With the improvement of the laparoscopic surgery, many urological surgeries can be safely and effectually performed by laparoscopic approach. The previously reported laparoscopic methods for treatment of adult obstructed megaureter were complex and time-consuming. To simplify the method, we modified the laparoscopic approach based on the previous methods. The innovative points of our novel technique are the extracorporeal tailoring of ureter and nipple ureteroneocystostomy. By this modified procedure, the time of operation can be obviously reduced while the procedure is effective. We hope this modified procedure will be accepted by more urologists.
