The preventive role of chemical sympathectomy on contralateral testicular hypoxic parameters encountered during unilateral testicular torsion.

OBJECTIVE

To evaluate the effect of chemical sympathectomy on lactic acid and hypoxanthine concentrations in both testes during unilateral testicular torsion in a rat experimental model.

MATERIALS AND

METHODS

Four groups, comprising 10 rats each, were studied. Group I was the control group, Group II rats received a placebo and underwent unilateral testicular torsion, Groups III and IV received guanethidine monosulphate and 6-OH-dopamine hydrobromide respectively, and underwent unilateral testicular torsion. The levels of lactic acid and hypoxanthine in both testes were measured.

RESULTS

In rats in Group II the levels of lactic acid and hypoxanthine in both testes were significantly elevated when compared to the control group. In the groups of rats that had undergone chemical sympathectomy, the levels of lactic acid and hypoxanthine were significantly decreased in the contralateral testes compared to rats in Groups I and II.

CONCLUSION

Chemical sympathectomy prevents the elevation of lactic acid and hypoxanthine levels in the contralateral testis of rats with unilateral testicular torsion. Therefore, we conclude that contralateral testicular damage during unilateral testicular torsion may result through a reflex activating sympathetic system.
