A nephrostomy set (percutaneous nephrostomy set) drains an obstructed kidney through a catheter that passes through the skin. A balloon-retained nephrostomy catheter, an access needle and dilators come in one pack. The catheter is a balloon catheter at Ch 12 or Ch 14, or a Ch 8 pigtail; the balloon holds the catheter in the renal pelvis.

A nephrostomy catheter takes the urine collected in the kidney out through a route that passes through the skin. It is used for percutaneous nephrostomy in an upper urinary tract obstruction, for urinary diversion before or after an endourological procedure, and for emergency decompression in obstructive pyonephrosis. The physician decides on the placement.
A nephrostomy catheter drains the kidney through the skin, and the urine goes to a bag. A DJ stent (ureteral stent) stays inside the ureter, between the kidney and the bladder. The physician decides which one is used.
The instructions of the treating centre apply to flushing, bag changes and dressing. A patient or a relative with a question or a complaint should contact the treating team.
