【 摘 要 】

PURPOSE: To evaluate the effect of decompression fasciotomy on testes undergoing torsion of the spermatic cord. METHODS: Spermatic cord torsion was induced in 40 Wistar testes for six and 12 hours. At the time of distortion, decompression fasciotomy was performed on half of the animals. After 42 days, the testicles were examined both macroscopically and microscopically. A non-parametric Mann- Whitney U- test was used for statistical analysis. The results were considered significant at p≤0.05. RESULTS: Testicular weight; volume and degree of histological alterations were evaluated. When the groups without and with fasciotomy were compared, a 12-hour torsion subgroup in the fasciotomy group was noted to present larger volume, heavier weight and superior histological classification when compared with the 12-hour subgroup in the without fasciotomy group. No differences between the two groups after six hours of torsion were found. No significant changes were noticed in the contralateral testis. CONCLUSIONS: Testicular fasciotomy (decompression) benefited the macroscopic and histological aspects of the testicles undergoing cord torsion for a 12-hour period. These results demonstrate the role played by compartment syndrome in the pathophysiology of spermatic cord torsion and the need for decompression.
