The urinary system disorders represent a large problem inruminants .These animals are directly affected with these affections,also their following biological changes and uremia may leadeventually to the death of the animal. This work was planned as atrial to solve these problems. The study implies in its clinical part inwhich the affected cases which were admitted to the clinic of theveterinary faculty of Zagazig University (2000-2007), governmentalfarms, farmers’ farms, veterinary clinics and solitary cases. Thestudy comprised (1621)animals (535 buffalo calves,498 cattle calves,270 sheep, and318 goats).Their ages range from two days to oneand half years. The results included and revealed the following:-I-The survey for urinary disorders:-Many disorders were recorded as following:-A-Congenital affections:(l)Patent urachus was 5.26%(0.12% of all affections),and recordedin one cattle calf and one buffalo calf.(2)Hypospadia was 28.95%(0.69% of all affections),andrecorded largely in goats.(3)Urethral dilatation was 65.790/0(1.56% of all affections). Inmale goats and cattle appeared as a swelling along the urethra,proximally in cattle and distally in goats. On exploration thecontent was urine and after its opening, it was lined by mucousmembrane.B-Acguired affections:(l)Urethral obstruction without urinary bladder rupture constitutesthe larger percentage 72.350/0(70.64% of all affections).Theaffection was less in small ruminants than in large ruminants,due to the tightness of the urethra and the adhesion between thepenis and the prepuce. The urethral obstruction was rare infemales than male due to the shortness and large bore of theurethra.(2)Urethral Perforation was 0.96%(0.93% of all affections).(3)Urinary bladder rupture was 26.69%(26.06% of all affections)
