The purpose of this research was to compare the immediate and later development of renal traumas occuring in dogs using, for their simulation, four methods: only renal trauma (Group A), the insertion of epiploon (Group B), use of a nylon membrane (Group C) and use of a vicril membrane (Group D). Forty dogs were studied, divided in four groups of ten each, in the vivarium of the Faculty of Medical Sciences, São Francisco University, Bragança Paulista, São Paulo State, Brazil. Following the carrying out of the techniques the dogs in Group A and B died in the first 42 hours, some dogs in Group C died during the first days due to infection complications and the rest of this group plus those in Group D were put down on the 85th day at which time the traumatised kidney and the contra lateral were removed, being studied macro and microscopically thereafter. This analysis was carried out in the Department of Pathology of the University of São Francisco. The results obtained were that the dogs in Group A and B (without using the membrane) died immediately post operation due to hemorrhagic shock, showing that the method of treatment was inefficient as the results for the dogs in Group C and D, in which the membrane was used, were better. The results in the initial phases using the vicril membrane (Group D dogs) were better when compared to the use of nylon (Group C dogs), although in the later phases these results were similar. Microscopic studies of the kidneys in which nylon was used (Group C), showed more fibrosis and granules of foreign bodies in the capsule when compared with the dogs in which vicryl was used (Group D). In the parenchyma kidney area no great differences were identified. It can therefore be concluded that the use of vicryl propitiates better hemostasis, better adhertion, fibrois and also does not cause large consequences in the kidney
