A simple decannulating method for suprapubic trocar and cannula without a side slit.

Closed suprapubic cystostomy using a suprapubic trocar and cannula is a standard surgical procedure for urinary diversion in cases of acute urinary retention. Decannulation is quite easy when the cannula has a side slit which allows easy detachment of the Foley catheter. However when the cannula is without a side slit decannulation becomes problematic. This simple decannulating method is described to overcome this difficulty.
