This study aimed to compare the clinical applications of "dual-knot continuous suture technique" (DKST) and "interrupted suture technique" (IST) in retroperitoneal laparoscopic dismembered pyeloplasty (RLDP). A total of 107 RLDP cases performed from January 2011 to February 2014 were retrospectively analyzed. According to the methods of ureteropelvic anastomosis, the patients were divided into the A group (27 cases that underwent DKST) and the B group (80 cases that underwent IST). The total

The total operative time, renal pelvis modification time, ure-teropelvic anastomotic time, postoperative hospital stay, drainage removal time, and complications such as urine leakage were compared. The mean total operative times of the A and B groups were 167.7 min (90-215 min) and 191.4 min (115-245 min), respectively (P=0.003); the mean ureteropelvic anastomotic times were 20.1 min (15-30 min) and 41.5 (20-70 min), respectively (P<0.001); the renal pelvis modification times, postoperative drainage times, and postoperative hospital stays showed no significant difference. The A group had no perioperative case of urine leakage, while the B group had 4 such cases. The postoperative 3 rd-month ultrasonography indicated that the A group had 16 cases of hydronephrosis disappearance and 11 cases in which hydronephrosis reduced by different degrees; the B group had 54 cases of hydronephrosis disappearance and 24 cases in which hydronephrosis reduced by different degrees. There was no recurrent case of hydronephrosis or anastomotic stenosis. The application of DKTS in RLDP could reduce the difficulty of ureteral anastomosis, shorten the operative time, and reduce the incidence of postoperative urine leakage.
