About Hydronephrosis Treatment (Pyeloplasty)

Both adults and children may require pyeloplasty, particularly when facing ureteropelvic junction (UPJ) obstruction. UPJ obstruction affects about one in every 1500 newborns, with males being twice as likely to have it compared to females. If the condition persists beyond 18 months in infants, pyeloplasty is often recommended.

Older children, teenagers, and adults can also develop UPJ obstruction, necessitating pyeloplasty if kidney function is compromised. Typically, each kidney has one ureter, which carries urine from the kidneys to the bladder. UPJ obstruction impedes this flow, elevating the risk of kidney damage, often affecting only one kidney.

Who Needs It?

Pyeloplasty is performed to relieve blockages in the ureteropelvic junction (UPJ), which connects the renal pelvis to the ureter.

Before Procedure/ Treatment

Open surgery, safer for babies with UPJ obstruction, involves direct visualization of organs without cameras, unlike laparoscopic surgery commonly used in adults. Laparoscopic pyeloplasty, under general anesthesia, is performed through small abdominal incisions, using a telescope and instruments to repair the blockage.

A ureteral stent may be inserted to aid drainage post-surgery and is usually removed after four weeks. Additionally, a drain may be placed to manage fluid around the kidney and pyeloplasty site.

Post-surgery, patients are advised to follow healthcare provider instructions, including light activity initially, gradually increasing activity levels, and avoiding heavy lifting. Showering is permitted, but patients should pat themselves dry. Driving should resume when comfortable and without narcotic pain medication.
