Evaluation of pinhole technique for castration in dogs

Abstract

The present study was undertaken on 12 healthy dogs presented for castration at TVCC, PGIVAS, Akola. The dogs were randomly divided into two groups (n=6), group A (pinhole castration) and group B (pre-scrotal castration). Different clinical parameters like surgical time, wound and pain score, haemato-biochemical and histopathological changes, testicular dimensions and sperm concentrations were assessed. Group A had 3 times shorter surgical time, better wound healing score, pain score and azoospermia postoperatively. The clinico-physiological and haemato-biochemical parameters showed insignificant alterations between the groups. The scrotal and testicular measurements revealed significant (P<0.01) atrophy of testicles as confirmed by degenerative and necrotic changes observed histopathologically. The study substantiated that pinhole castration rendered dogs infertile. Thus, it was concluded that the pinhole castration technique was satisfactory and an improved method of castration as it was quick, less painful with minimal surgical trauma when compared to conventional pre-scrotal castration.
