Firstly, a longitudinal oblique incision was made for approximately 0.5 cm until the bladder mucosa bulges into the incision. Then the bladder mucosa was incised, and 6-0 monofilament absorbable sutures placed through both ends of the incision. The ureter distal end was brought to the mucosa incision, and the mucosal sutures passed through the two sides of the distal end, and the ureter parachuted on to the bladder. The ureter was anastomosed to the bladder mucosa with continuous sutures between the ureter and the mucosa of the bladder. While the ureteric anastomosis was complete, the seromuscular layer was closed over the ureter with interrupted absorbable sutures.
