Intraperitoneal urinary bladder rupture is an uncommon condition, which is sometimes not so easy to diagnose.

Attention should be paid if there was a lower abdominal injury and ascites is found.

Full bladders are far more susceptible to rupture than is an empty one.

Surgical treatment is usually needed, like it was in this case - there was a wide gap in the bladder apex (approximately 4 cm), which had been closed.
