Nephrostomy (: Nephrostoma, v as well. Nephros . Greek νεφρός , "kidney" and stoma Greek. Στὁμα "artificially created gap", "mouth" or "orifice") refers to an artificial fistula through the renal parenchyma for urinary drainage from the renal pelvis by means of a Catheter . The corresponding operation is called a nephrostomy.

The catheter tip is placed in the renal pelvis and secured against slipping with a liquid-filled balloon. The catheter usually has to be changed every four to six weeks. If the catheter slips, it usually has to be reattached immediately.

A renal fistula becomes necessary when the flow of urine from the kidney is obstructed. A distinction is made between the open surgical and the minimally invasive, percutaneous fistula , in which the renal pelvis is punctured with a needle under ultrasound or X-ray control and a catheter is then inserted via a guide wire for urinary drainage.
