“…Kolbe et al first investigated whether torsion followed by capsulotomy resulted in positive histological outcomes in rat testicular tissue. 15 They concluded that testicular capsulotomy had no statistically significant beneficial effect on the testicular histopathology of torsion at times of 0, 8, 10 and 12 hours. However, their findings have been called into question due to the novel subjective histological scale used.…”

“…Kolbe et al 4 reported no statiscally significant testicular damage from "testicular capsulotomy" in Sprague-Dawley rats as assessed by testicular histological examinations. The results were inconclusive because of a large variability in the histologic response to torsion, regardless of whether the tunica albuginea was incised.…”

“…The pathologist was blinded to the torsion duration and to the fasciotomy performance status of each sample. Each testis was assigned a 0 to 6 histologic grade based on the following assessment of the seminiferous tubules, as described by Kolbe et al 4 . Changes noted in 5% to 50% of the crossed-sectional area of the testis.…”

Decompressive fasciotomy in testicular torsion of the spermatic cord in rats

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.

Effects of traction on the spermatic cord of rats

2014

PURPOSE:To determine whether tension in the spermatic cord of rats causes lesions in the testis, epididymis or vas deferens. METHODS:Forty Wistar rats were randomly allocated into four groups. A traction force of 1.6 Newton (N) in group I and 1 N in group II was applied to the right spermatic cord. Group III was the sham, and group IV served as the control. RESULTS:Testicular lesions occurred on the right side in 66.7% of the rats and on the left side in 46.1% of the rats. The testes showed a decreased number of Sertoli cells, necrosis and a decreased number of germ cells in the seminiferous tubules. Anatomopathological changes in the vas deferens were not identified. There was no decrease in the thickness of the muscle wall of the vas deferens. In the right epididymis, 71.8% of the animals showed a reduction and 5% showed an absence of intraluminal sperm. In the left epididymis, 37.5% of the rats showed a reduction. The volume and the final testicular weight of the right side in group IV was different from those in the other groups. CONCLUSIONS:Anatomopathological lesions were found in the testis and epididymis.
