Continuous ambulatory peritoneal dialysis is a usual method for the therapy of patients with end-stage renal failure. Some complications may occur during catheter insertion and cause significant morbidity. We report an inadvertent placement of a Tenckhoff catheter into bladder in a patient with end-stage renal disease. It has been known that history of peritonitis, previous abdominal surgery and neurogenic uropathy increase the likelihood of bladder perforation. Open surgical methods may be more appropriate for patients that have risk factors mentioned above.
