Intraluminal ureteral debris, hematomas or foreign body, which may mimic ureteral stones and tumors, are extremely rare cases. While renal colic and macroscopic hematuria are generally the causes for presenting, establishing the correct diagnosis with radiologic imaging is not always possible. In particular, urinary tract interventions such as previous intraabdominal operations, extracorporeal shock wave lithotripsy or percutaneous nephrolithotomy or usage of anticoagulant, the presence of ureteral hematoma, debris or foreign bodies in patient records should be considered in the definitive diagnosis. In this study we presented a 54-year-old female patient, who had right flank pain and macroscopic hematuria complaint for a month and had, grade 3 pelvicalyceal dilatation on the right side, filling defect in the right ureterovesical junction according to their intravenous pyelography. In our patient, we initially thought the cause as non-opaque ureteral stone or ureteral tumors, however we understood that the correct diagnosis was an organized intraureteral debris in 3 cm diameter after the diagnostic ureterorenoscopy.
