What is PCN placed to divert urine?

A PCN, or Percutaneous Nephrostomy, is a medical procedure in which a catheter is inserted through the skin into the kidney to drain urine when normal urine flow is obstructed. This intervention is typically performed when conditions such as kidney stones, tumors, or strictures prevent urine from passing through the urinary tract. By diverting urine directly from the kidney, PCN helps relieve pressure, reduce pain, and prevent kidney damage. It is often considered a temporary solution until the underlying issue can be addressed.
