Case histories of 91 patients with synchronous urinary tract polyneoplasias were analyzed. There were a total of 183 polyneoplasias, of them 116 and 67 neoplasms were located within and outside the urogenital system, respectively.

During a synchronous polyneoplastic process, urogenital tumors coincide in 26.4±4.6% of the patients. The kidney is most commonly involved (37.9±4.5%), the urinary bladder (33.6±4.4%) and prostate (19.8±3.7%) are less frequently. Synchronous tumors are located more frequently in the digestive system (49.3±6.1%), less frequently in the lung (16.4±4.5%) and skin (14.9±4.4%).

It is difficult to diagnose synchronous urinary tract polyneoplasias due to the fact that the second tumor is asymptomatic. As the result, the second tumor is missed in 28.9±4.5% of the patients on examination. Ultrasound study and endoscopy are the most informative diagnostic techniques.
