[Recuperation of ureteral peristalsis in the rat after denervation].
The paper presents the experimental work carried out on the influence of various surgical situations on ureteral peristalsis in the rat. It included 43 rats divided in three groups. Group I (n = 10) acted as control group and had only ureterolysis performed. In group II (n = 10), single section and subsequent anastomosis was performed. Group III (n = 23) included section at two levels, ureter extraction from the animal and subsequent autotransplantation of the ureter. The three groups were re-operated two months later to ratify peristalsis of the intervened ureter. Both in the first and second operations peristalsis, as well as the features and appearance of antiperistaltic waves were quantified. After 60 days, no changes were observed in group I, but groups II and III exhibited normal peristalsis to presence of antiperistaltic waves. Both groups had complications like stenosis, fistulas and hydronephrosis, but also normal functioning, histology and peristalsis.
