[A case of blind-ending bifid ureter--review of 114 cases reported in Japan].

A 45-year-old man was admitted to our hospital with a 3-month history of pain on micturition and a residual sensation. Intravenous pyelography demonstrated a duplication of the right ureter with one segment ending blind, measuring 2.0 cm in length and 0.4 cm in diameter. On CT scan of the abdomen, there was no evidence of an ectopic kidney at the distal end of the blind-ending branch. There have been 114 cases of blind-ending bifid ureter reported in Japan, including our own. Clinical aspects are statistically analyzed.
