Purpose: To evaluate the clinical value of ureteroscopy for the ureteral filling defect or obstruction on the excretory or retrograde pyelogram(RGP). Materials and Methods: The 72 patients with filling defect or intrinsic obstruction ureteral lesion on the excretory urogram or RGP underwent ureteroscopy to examine and treat the lesions. We used the 9.5Fr. or 11.5Fr. rigid ureteroscope with 5Fr. working channel. Results: The results were as follows; I. Among the 72 patients, 39 were male and 33were female. The mean age of patient was 45.7 years. 2. Ureteroscopy was successfully performed in 70 cases(97%) out of 72. In 2 cases, the advance of ureteroscope was failed. 3. Among 70 successful cases, ureteroscopy revealed 45 radiolucent stones, 9 ureteral stricture, 2 ureteral TCC. I metastatic tumor, 3 blood clot, each case of ureteral polyp, epithelial hyperplasia and Von-Brunn's nest. In 7 cases, no causative lesions were identified. 4. 41 out of 45 radiolucent stones were successfully removed by ureteroscopic procedure and 9 ureteral strictures were dilated. 6 cases of ureteral mass were successfully biopsied for pathological diagnosis. 5. 23 cases of post-operative or fever were treated conservatively and 10 cases of mucosal tearing and 1 case of ureteral perforation were treated with double-J stent indwelling. Conclusions: The ureteroscopy is effective modality to evaluate and treat in the ureteral filling defect or obstruction on the excretory urogram.
