nephrostomy

Full Definition

A nephrostomy is a surgical procedure that creates a direct connection between the renal pelvis and the skin surface, typically performed to relieve urinary obstruction or provide access for therapeutic interventions. The procedure involves placing a tube (nephrostomy tube) through the skin into the kidney to allow urine drainage when normal urinary flow is compromised. This intervention is commonly documented in operative reports and post-operative care instructions.

Usage
