輸尿管假性憩室是沿著輸尿管發生的小突出囊狀物，它們通常債多發性，兩側性且常發生在中上段輸尿管，一般要靠逆術性腎盂攝影才能診斷。因為病人有可能發生輸尿管移形細胞癌，定期的追蹤是必要的。此種病人有可能合併發生無痛性血尿和泌尿道感染。本篇報告兩個輸尿管假性憩室的案例並對以前有關的文獻做一回顧。

Ureteral pseudodiverticulosis consists of small outpouchings along the length of the ureter diagnosed primarily by retrograde urography. They are usually multiple, bilateral, and located predominantly in the upper and middle 2/3 of the ureter. Patients may be at risk of developing transitional cell carcimona, and interval follow up is suggested. Cases are associated with painless gross hematuria and urinary tract infection. We report on 2 cases that highlight the clinical characteristics of ureteral pseudodiverticulosis and review the previous literature.
