Abstract

We are reporting 7 cases of ureteral polyps associated with upper urinary stones. All of the 7 patients were male, ranging from 28 to 42 years of-age and the average was 36 years. Flank pain was complained in all cases but palpable mass was not noted. Microscopic hematuria was noted in 5 cases. The duration of symptoms ranged from 6 months to 10 years. The polyps were found on the right ureter in 2 cases and on the left ureter in 6 cases. The polyps were located at upper third ureter in 5 cases, at middle third in 2 cases and at lower third in 1 case. Excretory urogram and retrograde pyelogram revealed filling defects due to polyps in 2 cases and hydronephrosis or hydroureter proximal to the stones in all cases. Chronic inflammatory ureteral polyps were diagnosed histologically in all 7 patients. This investigation suggests that polyps are likely to develop in the cases of upper urinary stones which stays in one spot for a long duration.
