Cystofix catheter (14F) knotting within the bladder: an unusual complication.

Abstract Suprapubic bladder catheter (Cystofix) is commonly used to drain urine temporarily from the bladder. Common complications are hematuria, bladder wall edema, and bladder spasm due to the irritation by the catheter itself. Here a case is described where a suprapubic bladder catheter (Cystofix) became curled and knotted inside the bladder, probably the reason was the overdistended bladder and insertion of more than 10cm length of catheter inside the bladder rather than the diameter of the catheter.
