Nephrostomy Catheters are specialized drainage catheters designed to provide direct urinary diversion from the kidney when normal urine flow is obstructed. Commonly used in cases of urinary tract blockage, hydronephrosis, or post-urological procedures, they enable effective external drainage while preserving kidney function. Manufactured from biocompatible materials with features such as pigtail retention and radiopaque markings, nephrostomy catheters ensure secure placement, reliable drainage, and enhanced patient safety in both temporary and long-term clinical applications.
