To evaluate the effect of decompression fasciotomy on testes undergoing torsion of the spermatic cord.
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.
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.
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.
评估减压筋膜切开术对精索扭转睾丸的影响。
对40只Wistar大鼠的睾丸诱导精索扭转6小时和12小时。在扭转时，对一半动物进行减压筋膜切开术。42天后，对睾丸进行宏观和微观检查。采用非参数曼-惠特尼U检验进行统计分析。结果在p≤0.05时被认为具有显著性。
评估了睾丸重量、体积和组织学改变程度。比较未行筋膜切开术组和行筋膜切开术组时，发现筋膜切开术组的12小时扭转亚组与未行筋膜切开术组的12小时亚组相比，体积更大、重量更重且组织学分级更好。扭转6小时后两组之间未发现差异。对侧睾丸未发现明显变化。
睾丸筋膜切开术（减压）有利于扭转12小时的睾丸在宏观和组织学方面的恢复。这些结果证明了骨筋膜室综合征在精索扭转病理生理学中的作用以及减压的必要性。
