Laparoscopic pyeloplasty

Laparoscopic (Keyhole) pyeloplasty

Congenital Pelvi-ureteric junction (PUJ) obstruction may result in flank pain, recurrent renal tract infection or renal stone formation.

Surgical repair is only indicated for symptomatic PUJ obstruction. This entails excision of the obstructed segment and joining the renal pelvis back to the ureter with a series of sutures over a stent. The stent is removed 4 weeks after surgery. A MAG3 renogram is done at 3 months and 12 months after surgery to confirm resolution of obstruction.
