[Subperitoneal rupture of the bladder due to pelvic fractures. Apropos of 3 cases].

Three different approaches to the diagnostic and therapeutic management of bladder trauma were adopted in 3 patients. Haematuria was discovered on bladder catheterization. Emergency cystography remains the best diagnostic examination. CT has the same limitations as intravenous urography. There are two schools of thought concerning the treatment of the bladder lesion: surgical repair and healing by simple drainage. The indications depend on the size of the rupture and the severity of haematuria: intravesical clots and the need for continuous irrigation constitute contraindications to simple drainage. Emergency surgery must be combined with treatment of the bone lesions. Apart from external fixation, posterior osteosynthesis, when possible, is also indicated in unstable fractures.
