A clinical entity of multiple ureteral fibroepithelial polyps with annular stenosis and tortuosity: clinical features and management considerations

MASTUMP syndrome represents a clinical entity within complex ureteral polyps, potentially associated with congenital anomalies of the kidney and urinary tract. Endoscopic treatment carries a high risk of recurrence and should be approached with caution. Surgical resection with individualized reconstructive strategies offers durable outcomes. Further genetic studies and multicenter validation are essential to refine diagnostic criteria and treatment strategies.
