[Functional studies on the implanted ureter].

Electronical measurements of pressure in 8 successfully implanted ureters (6 Boari-Plastics, 2 direct implantations) yielded the following results. 1. Frequency, amplitude, duration and rate of spreading of the contractions show no differences compared to the normal ureter. 2. In the Boari-plastic the peristaltic activity is transferred also to the area of the anastomosis between bladder-flap and ureter. 3. Increasing pressure of bladder by retrograde filling produced temporary impairments of peristaltic of the implanted ureter in one case only.
