What is Percutaneous Nephrostomy?

Percutaneous nephrostomy is the placement of a catheter through the skin into the kidney's collecting system under ultrasound or fluoroscopy guidance to drain urine externally. It is used in obstructive uropathy, pyonephrosis and when a ureteral stent cannot be placed.

The procedure can be performed under local anaesthesia. A posterior lower-pole calyceal puncture is preferred. Catheter sizes are typically 8–12 French. Emergency nephrostomy can be life-saving in pyonephrosis (infected hydronephrosis).

A nephrostomy tube is a temporary solution; definitive treatment of the underlying obstruction must be planned. Catheter care and regular exchange (every 4–6 weeks) are an important part of patient education.

Symptoms

Obstructive renal failure (bilateral obstruction)
Pyonephrosis (infected, obstructed kidney)
Hydronephrosis due to ureteral stones
Malignant ureteral obstruction (tumour compression)
Cases where a ureteral stent cannot be placed

Risk Factors

Bleeding (perirenal haematoma)
Infection (sepsis risk)
Catheter dislodgement or blockage
Pleural effusion (with upper-pole puncture)
Colonic injury (rare)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When bilateral ureteral obstruction and renal failure develop
  • If pyonephrosis is suspected (fever and flank pain)
  • If urine output through the nephrostomy stops
  • If redness or discharge develops around the catheter

Treatment Methods

01
Ultrasound/fluoroscopy-guided percutaneous nephrostomy
02
Catheter exchange every 4–6 weeks
03
Antibiotic therapy in pyonephrosis
04
Definitive treatment of the underlying obstruction
05
Placement of a DJ stent once the obstruction is relieved
