  Robotic-assisted laparoscopic pyeloplasty (RAPP) for pyeloureteric junction obstruction has recently become widely performed. While dismembered technique is considered the gold standard in pyeloplasty, we experienced six cases in which non-dismembered technique was required and effective, out of 33 RAPP performed in our institute. The non-dismembered techniques were used in two patients with long stenosis, two patients having problems with ureteral blood flow, and two patients having severe hydronephrosis with high insertion of the pyeloureteric junction. The techniques employed were flap technique in two, Fenger method in one, an N shaped ureteroplasty in one, and bypass ureteropyelostomy in two. All patients undergoing either technique had favorable outcomes. Non-dismembered techniques should be important surgical alternatives of RAPP.
