The ureteral-fibro-epithelial polyp (UFP) is a rare benign tumor. An invagination of the ureter caused by a UFP is even rarer. Recommendations regarding diagnostics and treatment are based on previous case reports and expert opinions. UFP is mostly asymptomatic with microscopic hematuria as first symptom. CT with intravenous pyelography and a diagnostic ureterorenoscopy (URS) are best diagnostics options. Treatment is based on radical resection by endoscopic, laparoscopic or open procedure, depending on location and size. We present a case with a UFP causing a ureteral invagination.
