Clinical study conducted under field condition during the period from January 2005 to December 2008 in Beni-Suef province on a total number of 15 calves suffered from congenital urethral dilatation at the perineal region. Affection was diagnosed and treated surgically under field condition and treatment included perineal urethrostomy (8 calves) and surgical excision (7 calves). Results revealed that duration of surgery for urethrostomy was shorter (mean 36.25 minutes) than surgical excision (mean 85.71 minutes); bleeding was so extensive in surgical excision group than urethrostomy one; cost of surgery was lower for urethrostomy than surgical excision but the cost of its after care was twice that of surgical excision; complications were higher in urethrostomy group, recovery period was nearly the same in both groups (14.37 and 14.28 days); mean body gain was higher in surgical excision group (82 Kg) than urethrostomy group (77.14 Kg), and both groups considered low quality animals at market as a result of loss of breeding capability and urine scald. It is concluded that both techniques are satisfactory but surgical excision is superior to urethrostomy despite the higher cost and invasive surgical procedure.
