[Primary tumors of the ureter].

During the recent 18 years 13 patients aged 39-62 years with primary ureteral tumors were observed. The principal clinical symptoms were hematuria, pain in the lumbar region, a palpated kidney. the main diagnostic methods were as follows: cystoscopy, catheterization of the ureter, excretory urography (in early stages of the disease), retrograde ureteropyelography or antegrade pyeloureterography. Only radical surgery--nephro-ureteroectomy with resection of the urinary bladder wall around the ureteral ostium, performed in early stages, yields satisfactory results in 50-60% of cases. Indications to some or other kind of surgery should be formuated on the basis of express-biopsy results.
