Peritoneal extravasation during percutaneous lithotripsy.

Extravasation of irrigation fluid during percutaneous nephrostolithotomy is a major complication and can result in severe morbidity. We report 3 cases of peritoneal extravasation of irrigation fluid. Ventilatory difficulty and narrowed pulse pressure suggest intraperitoneal extravasation of irrigation fluid, which should be treated by rapid drainage of extravasated fluid and careful monitoring of electrolyte concentrations.
