Nephrostomie

Nephrostomy is a medical procedure that involves creating an opening through the skin into the kidney to drain urine. This is typically done when there is a blockage in the urinary tract, preventing urine from flowing out of the kidney. The blockage can be caused by kidney stones, tumors, blood clots, or other conditions that obstruct the ureter, the tube that connects the kidney to the bladder.

The procedure is usually performed under local anesthesia and sedation. A radiologist guides a thin tube, called a nephrostomy tube or catheter, through a small incision in the back and into the kidney. The tube is then connected to an external drainage bag, where urine is collected. This diversion of urine relieves pressure on the kidney, preventing further damage.

Nephrostomy can be temporary or permanent, depending on the underlying cause of the blockage. Temporary nephrostomy is often used to manage acute obstructions and allow for healing or further treatment. Permanent nephrostomy may be necessary in cases of irreversible obstruction or when other treatment options are not feasible.

Potential complications of nephrostomy include bleeding, infection, pain, and leakage of urine around the tube. Regular monitoring and care of the nephrostomy tube are essential to prevent complications and ensure proper drainage. The tube is usually removed once the obstruction is resolved or alternative management is established.
