Frequently asked questions

In most patients, yes. Relieving the obstruction lets the kidney drain normally and prevents further decline in function. If the kidney has already lost most of its function, the discussion shifts towards watching it, or occasionally removing it rather than repairing it.

Published success rates for robotic pyeloplasty are above 95% long-term. Dr Kooner's own series had complete relief of obstruction in all patients. A MAG3 renogram at three to six months confirms drainage; longer-term recurrence is uncommon and picked up on surveillance imaging.

Laser endopyelotomy is a non-reconstructive option performed entirely through the urethra. Success is around 75% and it suits shorter narrowings. Observation with periodic MAG3 renograms is reasonable if symptoms are mild and function is preserved. A true crossing vessel with recurrent pain is very unlikely to settle without reconstruction.

Most people notice they need to empty the bladder more often, have an urge to pass urine quickly, and have a little blood in the urine from time to time. Mild flank ache when the bladder is full is also common. Drinking normal amounts of water, avoiding heavy lifting, and regular paracetamol help. Symptoms settle within a few days of removal.

Desk-based work is usually possible within one to two weeks after a robotic or laparoscopic repair. Strenuous or physical work usually restarts around six weeks. Open pyeloplasty needs a longer break (two to three months). Stent symptoms can affect comfort until the stent is out.

Driving resumes when you are off strong painkillers and can do an emergency stop safely. Gentle walking is encouraged from day one. Higher-impact exercise and heavy lifting wait until about six weeks, or until after stent removal.

Yes - robotic, laparoscopic, and "keyhole" all describe surgery done through a few small incisions with a camera. Robotic pyeloplasty adds a surgeon's console, articulated instruments inside the abdomen, and 3D vision, which together make the fine stitching of the new ureter-to-pelvis join easier and more precise.

Previous endopyelotomy is not a barrier to a robotic or laparoscopic reconstruction, and is one of the clearer indications for going on to a pyeloplasty. Imaging is reviewed carefully to plan around any scarring from the earlier procedure.

The reconstructive principle is the same, but paediatric pyeloplasty is a specialist paediatric urology service. Dr Kooner treats adults with UPJ obstruction, including those diagnosed antenatally or as children whose symptoms return in adulthood.

Most patients manage on regular paracetamol and an anti-inflammatory where safe for the kidney. A short course of a weak opioid may be given for the first few days. Dr Kooner's team gives a written plan before discharge.
