Experimental model for ureteral autotransplantation in the rat.

The development of an experimental model for ureteral autotransplantation without kidney transplantation, in an attempt to confirm viability of the ureter after denervation and total ischemia, is reported. Stages of the study and the experimental microsurgical technique used are discussed. Experiments were carried out in 30 Sprague-Dawley rats distributed in two experimental stages. The absence of histologic lesions was demonstrated by exeresis of the autotransplantated ureter and latter pathological study. Size, colour, renal consistency, ureteral peristalsis and the macroscopic appearance of the surgical piece were recorded. Histological examination confirmed macro- and microscopic normality of the autotransplanted ureteral segment.

Ureteral obstruction and ureteral fistulas after aortofemoral or aortoiliac bypass surgery.

Ureteral injury after aortofemoral or aortoiliac bypass surgery has seldom been described in the literature considering the large number of bypass operations performed. Some causative factors, such as the position of the bypass, are obvious while others are less clear. However, no attempt has been made to unify criteria to establish a management protocol. Of 154 cases of ureteral units with ectasia reviewed ureteral fistulas were present in 19. Radiological ureteral obstruction appears to precede fistula formation. Symptoms, time of diagnosis and treatment according to the predominant etiology have been discussed. Etiological (in varying degrees of importance), clinical and diagnostic criteria, together with a management and therapeutic protocol in which early and late lesions are clearly differentiated were established, while bearing in mind that not all radiological obstruction patterns correspond to true ureteral lesions.

[Ureteral lesions produced by an aortofemoral prosthesis. Apropos of a case].

Ureteral lesions following surgery to aorta are reported infrequently. Since 1966, when Lytton published an account of ureteral obstruction from a graft anterior to ureter, several series have been published. In the present case the initial problem was to consider the diagnosis, masked by a supposedly abdominal symptomatology. The second stage was analysis of results of urography and tests of the fluid collection. Effective treatment of this serious complication with preservation of infection of graft was obtained in the case reported by conservative surgery by means of ureteral anastomosis.
