[Two cases of male ectopic ureter with hydroureter]

Abstract

Male ectopic ureters are relatively rare. We herein report two cases of male ectopic ureter. In case 1 a 34-year-old man had left renal hypertrophy incidentally found by ultrasonography. In case 2 a 58-year-old man had the chief complaint of urinary retention. These two patients had ectopic ureters opening into the posterior urethra with hydroureter and renal hypoplasia (Thom I), and nephroureterectomy were performed. There are 105 cases of male ectopic ureter in the Japanese literature. The type of the disease (according to Thom's classification), age distribution, opening site, associated abnormalities and treatment of male ectopic ureter were discussed.
