Robotic Pyeloplasty
Pyeloplasty is a reconstructive operation that repairs a narrowing where the kidney's drainage area (renal pelvis) joins the ureter. This narrowing is called a pelvi-ureteric junction (PUJ) obstruction.
PUJ Obstruction
A PUJ obstruction may be present from birth or develop later, sometimes because of a blood vessel crossing the ureter. Urine backs up and stretches the kidney, which can cause:
Intermittent flank pain, often after drinking large volumes
Kidney infections
Kidney stones
Gradual loss of kidney function
It is diagnosed with a CT scan and a nuclear medicine renogram, which measures drainage and the function of each kidney.
The Operation
Performed under general anaesthetic through small keyhole incisions
The narrowed segment is removed and the ureter is re-joined to the renal pelvis with a wide opening
A temporary internal stent is placed to support healing
Recovery
Hospital stay is usually one to two nights
The stent is removed four to six weeks later with a brief procedure
A follow-up renogram checks that drainage has improved
Risks
Risks include bleeding, infection, urine leak, stent-related discomfort and, uncommonly, recurrent narrowing requiring further treatment.
