title: [New trocar housing with an interchangeable cryotherapy sound for after-treatment of bladder outlet tumors].
abstract: The cryotherapy of tumours of the urinary bladder hitherto used by means of transurethrally introduced sounds with or without optics made necessary the development of an irrigation trocar casing with exchangeable cryotherapy sound for the entire therapeutic comprehension of all parts of the wall of the urinary bladder, particularly in the region of the outlet of the urinary bladder from 7 till 17 o'clock. The optic control is performed by means of a simultaneously suprapubically introduced trocar cystoscope. Thus also extremely localised tumorous changes in the region of the outlet of the urinary bladder (dead angle) are optically established and rendered accessible to cryotherapy.
