What is Pelviureteric junction obstruction?

Pelviureteric junction obstruction (PUJO) is a condition characterized by a blockage or narrowing at the junction where the renal pelvis, the funnel-like part of the kidney, connects to the ureter, the tube that carries urine from the kidney to the bladder.

This narrowing or blockage can impede the normal flow of urine from the kidney to the bladder.
PUJO can be caused by a variety of factors, including congenital abnormalities, such as an abnormal narrowing or abnormal positioning of the pelviureteric junction, or acquired conditions, such as kidney stones, scarring, or tumors. The obstruction can be partial or complete, and it can affect one or both kidneys.
When the pelviureteric junction is obstructed, urine accumulates in the renal pelvis, causing distension and increased pressure within the kidney.
