Sheaths and obturators Special sheaths are used for cystoscopy, i.e., examination of the lower urinary passages. Sheaths, obturators and visual obturators in various sizes from 17 mm to 25 mm are available. The cystoscopy sheaths are fitted with two fixed stopcocks.
Telescope bridges are used with cystoscopy sheaths in order to adapt the length for telescopes and enable use of instruments. The Mengal International range offers telescope bridges either without or with one or two working channels.
