A 53-year-old female was admitted to our hospital after right hydronephrosis was found on the CT scan taken at another hospital. The urinary cytology and culture findings as well as the urinary culture for acid-fast bacilli results were all negative. At our hospital, CT scan revealed a thickening of the right ureteral wall, and right hydronephrosis. In spite of the fact that retrograde pyeloureterography showed a right ureteric obstruction at the ureterovesical junction, cystoscopic examination demonstrated a normal bladder. Since right lower tract carcinoma was suggested, we performed right nephroureterectomy with bladder cuff. Histopathological diagnosis, however, revealed renal and ureteral tuberculosis.
