[Consequences of the communication between lower urodigestive organs on gonads and gonad ducts]

Though there are not many cases described in the literature and very few for children, the existence of lower urodigestive communications may give rise to inflammatory processes in gonads and gonaducts in the male. We have carried out an experimental study of this aspect on 248 male Wistar rats according to the following design: A 48 animal control group (C) is divided into four equal subgroups sacrificed at the ages of one, two, three and four months. The problem group (P) of 200 animals are all submitted to vesicosigmoidostomy and then 100 are sacrificed after one and two months, and the other 100 are dis-diverted one and two months after the original diversion and sacrificed one month later. No histological alterations were observed in gonads and gonaducts for the sacrificed control animals (n = 48). The animals sacrificed after diversion (44 per 100) showed the following histological alterations: five cases of testicular tube necrosis, two cases of deferent conduit inflammation, one case of deferent conduit necrosis, 12 cases of epididymis inflammation and 13 cases of epididymis necrosis. The animals that also underwent dis-diversion and that were later sacrificed (20 per 100) showed: five cases of testicular tube necrosis, one case of testicular inflammation, two cases of deferent conduit inflammation, four cases of epididymis inflammation and seven cases of epididymis necrosis. Statistical analysis showed that the differences between the two P groups were not significant.(ABSTRACT TRUNCATED AT 250 WORDS)
