A male aged 20 had been treated for anal and lower abdominal pain after ejaculation for about 2 years under the diagnosis of chronic prostatis. Because of worsening of the pain, he was admitted to our hospital in September 24, 1991. On the rectal examination, a cystic tumor was palbable on the left side of the prostate. The left kidney was not detected by IVP and ultrasonography. CT revealed two retrovesical cystic lesions in the left side. Cystourethroscopy showed an absence of ureteral orifice and ureteral ridge on the left side. Left uretero-seminal vesiculectomy was performed on October 3rd, under the diagnosis of an ectopic ureter entering into the seminal vesicle or ejaculatory duct. Histopathologically, the left ectopic ureter entering into the lower portion of the seminal vesicle or ejaculatory duct and the left renal agenesis were diagnosed. It was remarkable that ureteral epithelium was not transitional but columnar epithelium.
