Percutaneous nephrostomy is a procedure where a drainage tube (nephrostomy tube) is inserted through the skin and into the kidney to drain urine, often used to relieve urinary obstruction or provide access to the kidney for other procedures. It’s a minimally invasive technique, typically guided by imaging such as ultrasound or fluoroscopy, and can be performed to treat various conditions including kidney stones, infections, and ureteral injuries. 

More Details:

• Purpose:Percutaneous nephrostomy is performed to drain urine from the kidney when there is an obstruction in the urinary tract, such as from kidney stones, tumors, or other conditions. It can also be used to provide access to the kidney for other procedures, like stone removal or stent placement. 
• Procedure:The procedure involves inserting a needle through the skin, into the kidney’s collecting system (usually under ultrasound or fluoroscopic guidance), and then placing a drainage tube (nephrostomy tube) into the kidney. 
• Indications:Common reasons for percutaneous nephrostomy include:
  • Relief of urinary obstruction: This can be due to various causes, including kidney stones, ureteral strictures, or tumors. 
  • Urinary diversion: It can be used to divert urine in cases of traumatic ureteral injury or fistula. 
  • Access for other procedures: It provides access for procedures like stone removal (percutaneous nephrolithotomy), dilatation or stenting of ureteral strictures, and biopsy of urothelial lesions.
