Deviation of the Ureters due to Giant Bladder Diverticula.

Vesical diverticula may on occasion reach very large size, containing more urine than the bladder proper. Depending on its position, a diverticulum may cause displacement of the lower ureter. Medial deviation of the pelvic ureter, by which a non-visualized diverticulum may be diagnosed, is not rare. The case to be described is exceptional in that both medial and lateral deviation of the ureters was present in the same patient, due to giant bilateral diverticula.
