Genito-urinary polyps: summary of the 10-year experiences of a single institute

We present a large series of polyps situated in various parts of the urinary tract in adults, including 12 cases of fibroepithelial polyps, four cases of eosinophilic cystitis, three cases of benign prostatic epithelial polyp, and one case of transitional cell carcinoma presenting as a bladder polyp. Data on 23 patients with polyps in the urinary tract treated in our department from December 1995 to December 2005 were reviewed. The characteristics of the patients, disease, and treatment modalities were recorded. Of the 23 patients treated in our institute during the study period, seven had polyps in the ureter, eight had polyps in the bladder, and eight had polyps in the urethra. Twenty-one patients underwent endoscopic resection of the polyps, and two patients were managed conservatively with medical therapy. Twenty-two polyps were benign (fibroepithelial polyps, benign prostatic epithelial proliferations, eosinophilic cystitis), and in one patient transitional cell carcinoma presented as a bladder polyp. Postoperative recovery was excellent. Mild hematuria manifested in two patients during the perioperative period, but there was no recurrence in the follow-up period. Two patients with a urethral polyp managed with endoscopic resection developed urethral stricture during the postoperative period and required repeated urethral dilatations during the follow-up period. The presence of polyps in the urinary tract is rare. The treatment of choice is endoscopic resection, and the prognosis of these patients is excellent.
