FIELD: medical engineering.

SUBSTANCE: device has catheter having the first end open and additional tubes. The catheter lumen is 2.0-5.0 mm and wall thickness is 1.0-2.5 mm as large. The catheter has cup seal mounted on lateral surface near the first open end, the second rounded dead end and lateral openings for attaching additional tubes near the second dead end. The additional tubes are manufactured as additional ureteral drains. Lumen space near the first end and lumen space near the lateral openings located aside of the middle portion of catheter are manufactured to receive adapters for connecting a system for collecting urine.
