Abstract

The current study was designed to compare two urethrotomy techniques (ventral and dorsal urethrotomy) to find out the short and long-term complications that may occur with both techniques and their incidences, to record the success rates of both techniques and to give full description of the new dorsal urethrotomy technique. The study was carried out on 50 cattle-claves suffered from urine retention, due to urethral obstruction by uroliths and cystorrhexis. Affected calves were classified randomly into two equal groups and one urethrotomy technique was used in each group for extraction of the stones. The operated calves were followed up for one year post-surgery and complications were recorded. Results revealed higher incidence of post-surgical complications in group A than B, as the minor short-term complications like cystitis, abscess formation at sigmoid flexure, and wound edema constituted 56% and 16%, in both groups respectively. At the same time, the major short-term complications like ruptured urethra and peritonitis represented 32% and 4% in both groups respectively, while the long-term complications including re-obstruction and adhesion of sigmoid flexure were 28% and 4% in both groups respectively. Consequently the dorsal urethrotomy technique had higher success rates and accordingly it is concluded that the dorsal urethrotomy technique is advised to be used as an alternative technique to the traditionally used ventral urethrotomy in cattle-calves, when preserving the breeding capacity of calves is in demand.
