Pyeloplasty is reconstructive surgery for pelvi-ureteric junction (PUJ) obstruction. This can be performed as an open, laparoscopic or Da Vinci robotic laparoscopic procedure. Robotic and laparoscopic pyeloplasty use the same operative principles as an open pyeloplasty. The surgery is performed under a general anaesthesia and 3 to 4 small incisions are made in the abdomen to place the ports into the abdomen to perform the keyhole surgery. At the end of the operation, a ureteric stent ( small plastic tube) is left internally to splint and protect the anastomosis between the ureter and renal pelvis. The ureteric stent is removed 2-4 weeks later under a local anaesthetic. The benefits of a Da Vinci robotic and laparoscopic pyeloplasty are smaller incisions, less post-operative pain, quicker recovery, shorter hospital stay, improved cosmesis, less infection, less hernia, earlier return to work and more precise anastomosis of the PUJ with the Da Vinci 3D robot due to superior views and instrumentation.
