Abstract：Objective:To evaluate its feasibility and clinical significance of transperitoneal laparoscopic pyeloplasty on ureteropelvic junction obstruction. Methods:From February 2009 to July 2012, 34 cases of ureteropelvic junction obstruction were operated with transperitoneal laparoscopic pyeloplasty. In all of these cases, 18 patients were male. The numbers of patient with left-side lesions were eighteen. Results:The operations were all successful in 34 cases. The mean operating time was 114 min (range from 105 to 195 min). Mean blood loss was 34.7 ml (rang from 20 ml to 50 ml). One case was found leakage of urine. Ureteral stenosis was found in another one case six months after operation. The mean postoperative hospital stay was 6.5 days (rang from 5 to 7 days). Hydronephrosis subsided in 13 cases and completely disappeared in 9 cases under B-ultrasonography. Success rat of surgery is 97%. Conclusions:The transperitoneal laparoscopic pyeloplasty has the advantages of good exposure field, less blood loss and rapid postoperative recovery and high success rate. It is new choice for treatment of ureteropelvic junction obstruction and worth popularizing and applying.
