What Is a Upj Obstruction

Ureteropelvic junction (UPJ) obstruction is a blockage in the area that connects the renal pelvis (part of the kidney) to one of the tubes (ureters) that move urine to the bladder. It generally occurs when a baby is still growing in the womb. This is called a congenital condition (present from birth).

Is UPJ obstruction serious?

If undiagnosed or left untreated, chronic UPJ obstruction can lead to significant kidney damage and the gradual loss of kidney function. This is especially true of patients who are diagnosed later in life. Urinary tract infections become common and can be more serious than usual.

How long is UPJ obstruction surgery?

The typical length of the operation is three to four hours. The surgery is performed through three small (1 cm) incisions made in the abdomen.
