Hydronephrosis refers to the swelling of the kidney caused by the collection of urine. Surgery would be recommended only in the most severe cases. The goal of the surgery is to reduce swelling and pressure in the kidney by establishing a free flow of the urine. The most common surgical procedure used for the treatment of hydronephrosis is pyeloplasty. Pyeloplasty repairs the most common type of blockage, that is, the blockage at the point where the kidney joins the ureter (ureteropelvic junction blockage). It removes the narrowed or obstructed part of the tube connecting the kidney to the bladder (ureter) and reconnects the healthy portion to the kidney’s drainage system. The surgeon  may perform pyeloplasty in:

What is hydronephrosis?

Hydronephrosis involves the collection of urine in the kidney due to incomplete emptying of the urinary tract. This results in swelling and obstruction of the kidney. The swelling or obstruction can occur at:

  • Opening of the kidneys into the ureters
