Cryodestruction technique in the prostatic gland in dogs.

Abstract

The investigation aimed at selecting the best parameters of cryodestruction of the healthy prostatic gland in dogs. Freezing was performed from the external side of the gland. The investigations were carried out on 2 healthy dogs in which the prostatic glands were frozen with two different methods and then, 4 weeks later, the degree of the gland size decrease was estimated. Both dogs were subjected to the unifocal cryodestruction of the lobes of the prostate. The comparison was made of the usefulness of the flat and spear-headed applicators in the freezing procedure performed in a single or repeated cycle. Also two methods of taking the temperature of the urethra to protect it against overfreezing were compared. It was observed that the greatest decrease of the gland (by 55%) was obtained while using flat applicator and the repeated freezing cycle. Flat applicator does not cause any significant bleeding after the gland thawing.
