Abstract
Two female dogs with voiding difficulty were referred to our hospital after a failure of the urethral catheterization. A series of diagnostic examinations revealed a tortuous urethra with no evidence of tumors, calculi or inflammation in both cases. Manual bladder expression became possible after cranial traction of the bladder, suggesting that dysuria in these dogs was caused by a tortuous urethra. After cystopexy, symptoms were alleviated, and favorable therapeutic outcomes were achieved in both dogs.
