title: Twisted fate of bladder catheters.
abstract: Catheter knotting is a rare complication of bladder catheterisation. Retention of catheter parts resulting in calculus formation is even rarer. We report a case of a vesical calculus formed over a broken and retained supra-pubic catheter which to the best of our knowledge has yet to be reported, along with three other cases of bladder catheter knotting.
