Pelvi-Ureteric Junction (PUJ) Obstruction

Robotic-assisted pyeloplasty is a minimally invasive surgical procedure used to treat pelvi-ureteric junction (PUJ) obstruction, a condition where the flow of urine from the kidney to the ureter is blocked or restricted. This advanced technique uses robotic technology to enhance precision, minimise recovery time, and improve outcomes compared to traditional open surgery.

Robotic-assisted pyeloplasty is recommended for patients with PUJ obstruction, which may cause:

  • Flank or abdominal pain
  • Recurrent kidney infections
  • Kidney stones
  • Reduced kidney function
  • Swelling of the kidney (hydronephrosis)


The condition may be present from birth or develop later due to scarring, previous surgery, or kidney stones.

How is the Procedure Performed?

The procedure is performed under general anaesthesia, and a few small incisions are made in the abdomen to allow the robotic instruments to be inserted. The surgeon, controlling the robotic system, uses high-definition 3D vision and highly precise instruments to perform the repair. The obstructed section of the ureter is carefully removed, and the healthy portion is reconnected to the kidney to restore normal urine flow. In most cases, a temporary stent is placed inside the ureter to support healing. Once the repair is complete, the instruments are removed, and the incisions are closed. Most patients stay in hospital for one to two days and can resume normal activities within a few weeks.

Benefits of Robotic-Assisted Pyeloplasty

  • Less pain and reduced need for pain medication
  • Smaller scars and better cosmetic results
  • Shorter hospital stay and quicker recovery
  • Improved precision, reducing the risk of complications
