Bladder rupture in male cattle

Recently, I’ve had serious problems with my cattle. They seem to be unable to urinate and have severe abdominal pain. When they drink water, they suffer from abdominal distension followed by bladder rupture. The urine floods the stomach and the animal dies. We´ve tried using different antibiotics but with no results. I would appreciate it if you could give me any information regarding this disease, since I have lost about 75 calves of different weight so far, Thanks,
