Contemporary evaluation of urography in diagnosis in patients with urothelial cell carcinoma.

312 Background: Upper urinary tract tumors (UUTT) can occur synchronous or metachronous (0.7 – 6%) with bladder tumors. The optimal imaging technique of the upper urinary tract is unclear. Studies on the accuracy of retrograde pyelography (RUP) and comparative studies on detection level are sparse. In this study we evaluated the effectiveness of a first RUP in patients with a first manifestation of urothelial cell carcinoma (UCC) in the urinary tract. Methods: In this retrospective study we evaluated all consecutive patients with pathologic proven UCC who underwent their first RUP between March 1998 and April 2008 in the University Medical Center Groningen, Netherlands. Data regarding patient and tumor characteristics, results from RUPs, use of alternative imaging techniques, treatment and outcome were collected from the electronically patient’s records. Follow up was calculated from the first RUP to the last registrated visit. Descriptive statistics have been used to evaluate the performance of the RUP. ...
