[3 experimental contributions to the regeneration of the ureter]

In this paper three experimental series were described in which on dogs the regeneration of the ureter from a longitudinal stripe of its wall was investigated on several conditions. The variations concerned permanently lacking or beginning at different moments after operation urinary flow, immobilisation of the margins of the stripe by sutures, splinting by means of ureteral catheter, suturing of the stripe with one side of the mucous membrane on the serosa of the large intestine, transverse cutting of the stripe with following uniting of the stumps, applications of prednisone and immuran for pre- and aftertreatment. The results were tested radiologically, autoptically and histologically. In their majority they were good and may partly be used clinically.
