OBJECTIVE To describe a modified suture technique for transperitoneal laparoscopic dismembered pyeloplasty (TPLDP) that can be consistently replicated. @@@ METHODS Between June 2010 and April 2014, 21 men and 7 women with primary pelviureteric junction obstruction underwent our modified TPLDP suture technique performed by the same surgeon. In our method, the dismembering should be performed after performing half of anastomosis to achieve the maintenance of correct orientation and the prevention of torsion of anastomosis. We defined the success criteria as complete clinical resolution of flank pain for the patients with flank pain and complete radiologic resolution for the asymptomatic patients. @@@ RESULTS The mean overall operative time for our technique was 137.3 minutes. The mean operative time for procedures on the left side was longer than on the right side (P =.02). The mean suture time was 37.2 minutes. The mean estimated blood loss was 29.4 mL, and the crossing vessel was found in 7 of 28 patients (25.0%). No open conversion was required. The mean follow-up time was 21.0 months. Only 1 patient still had frequent and intolerable flank pain after surgery whose treatment was unsuccessful. The rest of the patients got complete clinical or radiologic resolution. The success rate was 27 of 28 (96.4%). @@@ CONCLUSION Our modified TPLDP suture technique is feasible and seems to be safe and to allow high success rate for the treatment of pelviureteric junction obstruction. Sizable sample and further analysis about technique will be completed in the future.
