title: [Determination of optimal length of extramural tunnels for their adequate anticurrent properties in intestinal urine derivation].
abstract: An acute experiment on adult dogs with conduction of manometry in outlets and inlets in reservoir filling and with Valsalva's test has established that reliable continent properties of the anti-current mechanisms are provided in creation of the tunnel with functional length 5 cm minimum leading to proportional rise in pressure in reservoir and in outlet. Pressure in the outlet was approximately 2 times higher than in the reservoir. In tunnel length 4 cm Valsalva's test registered leaking. The results obtained contributed to effective clinical use of the method.
