Transurethral Resection Syndrome Caused by Bladder Perforation during Transurethral Resection of Bladder Tumor: A Report of 2 Cases

Abstract

Transurethral resection (TUR) of bladder tumor may be complicated with bladder perforation associated with intraperitoneal and retroperitoneal extravasation of irrigation fluid, which may rarely evolve in specific hydroelectrolyte imbalance characterized with hyponatremia, intravascular volume deficit, and renal impairment. Signs and symptoms of cardiovascular dysfunction secondary to hyponatremia, prolonged resection, and intravascular volume deficit may also occur, such as severe hypotension, bradycardia, and cardiac arrest. It is most important to prevent TUR syndrome by using an accurate technique. If bladder perforation occurs, early detection is important for the appropriate treatment.
