A fifty-four year-old male presented to our O.P.D. with intermittent grosshematuria. Three months before, he underwent transurethral biopsy of the bladder at another hospital under the clinical impression of bladder tumor, however, the pathology showed no significant findings. Urine cytology demonstrated cluster of atipical cell compatible with class IV to V. Excretory urogram showed moderate left hydro-nephrosis and ipsilateral ureteral obstruction at its lower segment. Endoscopic examination revealed no apparent abnormal findings of the bladder and posterior urethra except for the edematous change of the left hemitrigonum.
