Bowel Perforation During Percutaneous Nephrolithotomy: Diagnosis, Management, and Follow-up.

ABSTRACT

Percutaneous nephrolithotomy (PCNL) is the procedure of choice for large kidney stones, but serious complications such as bowel perforation may occur. We discuss the diagnosis and management of colonic and small-bowel perforations due to PCNL and suggest principles for care and prevention. We emphasize the significance of imaging tools to direct percutaneous access, the importance of early diagnosis, and the relatively high success rate for conservative management. Patient summary: Large kidney stones are usually treated with a keyhole surgery procedure called percutaneous nephrolithotomy (PCNL). A rare but serious complication of this procedure is puncture of the bowel. We discuss how to prevent, diagnose, and treat this complication in patients undergoing PCNL.
