Observations on experimental perineal exteriorisation of the bovine urinary bladder.

A new technique for perineal exteriorisation of the urinary bladder was evolved and successfully performed in 15 buffalo calves (Bubalus bubalis). Its merits are maximum visibility of the bladder for cystorrhaphy and easy digital accessibility to the bladder neck. An indwelling urethral catheter made of polyvinyl chloride tubing with an improvised wire stilette was well tolerated for up to 20 days.
