Pelviureteric junction obstruction and pyeloplasty

Pelvic ureteric junction obstruction and Pyeloplasty

Pelvic ureteric junction obstruction (PUJO) is a blockage where the kidney pelvis join the ureter. This is an internal narrowing or a blood vessel causing external compression. When untreated, this causes worsening kidney function, swelling of the kidney (hydronephrosis) and predisposes to injury and pain.

Treatment:

PUJO is treated with the Anderson Hynes pyeloplasty under general anaesthesia. The
blockage is removed and the unobstructed ureter is joined to the kidney. A stent is left within the new joint to promote patency.

Follow up care:

Drink adequate amounts of water and record the urine output. The stent will be removed at a later date. Imaging will be used to assess resolution of the obstruction.
