Abstract

PURPOSE:

To assess the incidence of testicular necrosis/atrophy immediately after 1 to 4 hours of 1,080-degree torsion of the spermatic cord, and 60 days after detorsion of the spermatic cord.

METHODS:

42 rats were divided in 7 groups. Except for the control group, surgical torsion of the right spermatic cord was performed in all groups (T0). After 1, 2, or 4 hours of torsion, each group underwent either ipsilateral orchiectomy (groups OT1, OT2, and OT4), or detorsion of the spermatic cord and observation for 60 days (groups DT1, DT2, and DT4), before they were evaluated for the presence of testicular necrosis/atrophy.

RESULTS:

Only one rat (5.5%) in groups OT1, OT2, and OT4 had testicular necrosis, in comparison with six rats (33.3%) in groups DT1, DT2, and DT4 (p=0.04). The incidence of testicular necrosis/atrophy was not different between subgroups T1, T2, and T4, and the control group (p>0.05). There was, however, a tendency toward greater incidence of necrosis/atrophy in the rats in group DT4.

CONCLUSION:

The incidence of testicular necrosis/atrophy immediately after 1 to 4 hours of 1,080-degree torsion of the spermatic cord is 5.5%, in comparison with 33.3% sixty days after detorsion of the spermatic cord.
