Incarceration of small bowel following percutaneous nephrostomy tube insertion

Percutaneous nephrostomy has become a well-established technique for providing permanent or temporary drainage of an obstructed urinary system for decades. Although it is generally considered a safe intervention, some complications might be life threatening. Here we present a case of bilateral nephrostomy insertion due to T-cell lymphoma, that presented with signs of bowel obstruction 3 weeks after intervention. Abdominal exploration showed bowel obstruction due to invagination of bowel loop between left nephrostomy tube and abdominal wall which resolved by release of bowel loop and changing nephrostomy route to pass through retroperitoneum only.
