Fibrous Polyp of the Ureter Fibrous polyps of the ureter are benign tumours of mesodermal origin. They are very uncommon and a recent review of the literature showed 37 cases (Stuppler and Kandzari, 1975). Case Report A 24-year-old man was admitted to the hospital with a several-month history of intermittent crampy abdominal pain on the right side. Physical examination was unremarkable except for a left varicocele. Urinalysis showed many red cells. Intravenous urography revealed an elongated smooth filling defect in the lower third of the right ureter above a small radio-opaque stone (Fig. 1). The patient underwent exploration of the right lower ureter. The stone was removed through a longitudinal ureterotomy and a glistening worm-like polyp extruded, measuring 3 cm in length, attached by a narrow stalk to a small area of the ureteric wall. A 3 cm ureteric segment was excised with the lesion and an end-to-end

anastomosis was carried out. Convalescence was uneventful and follow-up IVP was normal. Microscopic examination revealed fibrous stroma lined by normal transitional cell epithelium (Fig. 2). The pathological diagnosis was fibrous polyp of the ureter. Comment

Fibrous polyps of the ureter have been reported in patients of all ages of life. Their most common location is the ureteropelvic junction or the upper ureter. The aetiology of this tumour is not well established. Fibrous polyps are frequently associated with urinary infection or chronic irritation of the ureteric wall, as in our patient, carrier of a ureteric stone for several months. However, the absence of infection in many cases and the youthful age of some patients suggest also a congenital origin. The characteristic radiological finding is a smooth and often elongated intraluminal filling defect. Local excision of the polyp with partial ureterectomy or simple fulguration is the treatment of choice. Reference Stuppler, S. A. and Kandzari, S. J. (1975). polyps of ureter. Urology, 5, 553-558.
