[A long-term survival after partial nephrectomy in a case of pelvic tumor arising in a solitary kidney].

A 44-year-old man was admitted on January 21, 1975 because of asymptomatic hematuria. The patient had nephrectomy of his left kidney due to nephritis at the age of three. Cystoscopy revealed no abnormalities, and excretory urography showed an irregular filling defect and slight ectasia in right upper calyx. A clinical diagnosis of pelvic tumor of the right kidney was made and partial nephrectomy was performed on April 18, 1975. The resected kidney was 4.5 X 5.0 X 6.5 cm in greatest dimension and the tumor was well localized in the upper calyx. Pathological diagnosis was transitional cell carcinoma, papillary, grade 11, stage 1. About 2 years after the operation, the patient developed a rice-sized tumor in the bladder neck followed by transurethral resection. Otherwise he is in good condition to date, 7 years and 4 months after the partial nephrectomy.
