The term of ectopic ureter means the ureter which opens at a point other than ther lateral horn of the interureteric ridge. Single ectopic ureter ureter is very rare and it accompanies renal anomaly commonly. We experienced a case of single ectopic ureter of which orifice opened into the uterine cervix in 18 year girl. She had suffered from urine leakage through the vagina in spite of normal voiding since childhood. Nephroureterectomy was performed and surgical specimen revealed hypoplastic kidney and marked hydroureter. We report this case with review of literatures.

Primary neoplasms of the epididymis are quite rare, but most have benign and cystic natures. Papillary cystadenoma of the epididymis occurs most often in young adults and produces either mild local discomfort, dull pain or no symptoms. This tumor has characteristic histopathologic findings which show affinities to many of the mesonephric tumors of the female genital tract. It is experienced a case of papillary cystadenoma of the left epididymis in young man who was treated with reselection of adenomatoid tumor at the same site one year ago. Authors report a case of papillary cystadenoma which was resected with good result and review of the literature.

Most of the testicular tumors are malignant and metastasis occurs relatively early. They are usually developed during the age of greatest sexual activity, between the ages of 18~35 years, and they account for about 0.5% of all malignancies in men and 4% of all tumors affecting the genitourinary tract. Bilateral primary testicular tumors account for 0.6~3.8% of all testis tumors. Up to date 40 cases of bilateral primary testicular tumors thar proved histologically to be primary tumor have been reported.

Recently authors have experienced in the right testicle and seminoma developed in the left underscended testicle. A brief review of the literature and a disccusion concerning bilateral primary testicular tumors are presented in this paper.
