BACKGROUND: Intrinsic @entity1901 is rare. Early detection and treatment is extremely important to preserve renal function. CASE: A 37-year-old @entity1 with @entity812 was diagnosed with a polypoid lesion at excretory urogram. The polyp was removed under ureteroscopy and was found to be @entity46 . Subsequent exploratory laparotomy and ureterolysis failed to document other foci of @entity46 . Resection of the ureter was not needed. She received @entity7839 for 6 months, and a ureteral stent was left in place for 3 months postoperatively. Excretory urogram showed no obstruction 6 months postoperatively. CONCLUSION: This appears to be the first reported case of @entity1901 documented initially at ureteroscopy. Prompt treatment may relieve symptoms and preserve renal function. Resection of the ureter may be avoided in some @entity1 .

Ureteral XXXX diagnosed at ureteroscopy.
