Abstract
An 11-month-old entire male Cob colt was presented for unilateral cryptorchid castration and intermittent purulent urethral discharge. Cystoscopy, trans-cutaneous and trans-rectal abdominal ultrasonography and contrast enhanced computed tomography examinations confirmed unilateral cryptorchidism, ipsilateral renal dysplasia and pyoureter with dilatation and ectopia. While nephrectomy may be a viable treatment approach for some cases of unilateral renal dysplasia, surgical intervention was not attempted in this case owing to financial constraints and the yearling was subjected to euthanasia. To the authors' knowledge, this is the first report of a case of complex congenital urogenital malformation including ipsilateral renal dysplasia, pyoureter with dilatation and ectopia and cryptorchidism, a finding which has been reported more commonly in human males.
