緒言
尿路粘膜の腺性化生は比較的稀な疾患であり,かつ臨床的診断,治療のみならず,病理組織学的にもいろいろと問題が多い。文献上,膀胱の腺性化生についてはかなり多くの報告をみるが腎盂尿管の腺性化生疾患についての報告は予想外に少ないようである。われわれは尿管切石術の際,結石嵌入部に発見された尿管ポリープの一部に典型的腺性化生をみとめた2例について報告する。
The relatively rare two cases of ureteral polyp with glandular metaplasia associated with ureteral caluculus are reported and glandular metaplasia was discussed. Glandular metaplasia or ureteritis glandularis is not essentially malignant, but is considered to be precancerous change. Therefore careful long term follow-up is necessary in such case.
Two patients (45 and 44 yearold-male), visited our clinic complaining colicky left flank pain. X-rayexamination revealed a small sized stone of the left middle ureter and left ureterolithotomy was done.
