Percutaneous Nephrostomy in Zurich<\/strong> \u2013Immediate Relief for the Obstructed Kidney<\/span><\/span><\/h1>

The kidney produces urine around the clock. When drainage is blocked \u2014 by a kidney stone, a ureteral stricture, or a tumor pressing from outside \u2014 urine backs up in the kidney. Pressure rises, the kidney swells, and if the obstruction persists, permanent kidney damage threatens. In acute cases, life-threatening urosepsis (blood poisoning from urinary tract infection) can develop within hours.<\/p>\n

Percutaneous nephrostomy \u2014 an image-guided drain through the skin directly into the obstructed kidney \u2014 provides relief within minutes.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/section>

What Is Percutaneous Nephrostomy?<\/h2>\n<\/div><\/div>
<\/div><\/div>

Percutaneous nephrostomy (PCN) is a minimally invasive procedure in which, under ultrasound and fluoroscopic guidance, a thin drainage catheter is inserted directly through the skin and back muscles into the renal pelvis. The backed-up urine can immediately drain, the kidney is relieved, and \u2014 if infection is present \u2014 the vicious cycle of urosepsis is broken.<\/p>\n

A nephrostomy can serve as a temporary measure (e.g., until a kidney stone can be surgically removed or fragmented) or as a permanent drainage pathway when the ureter is permanently blocked (e.g., by a tumor).<\/p>\n
