Late postoperative results in males treated for testicular torsion during childhood.

Successful preservation of a testis that has undergone torsion is directly related to the duration and degree of torsion. From 1979 to 1991, 75 cases of testicular torsion were treated. Eleven orchiectomies were performed; operative detorsion was done in the other 64 cases, with concurrent orchiopexy of both testicles. Twenty-five patients were reexamined 1 to 12 years after the surgery. Age of torsion, duration of symptoms, and operative findings were reevaluated. Testicular volume was determined using Prader's orchidometer, a pachymeter, and ultrasonography. In four postpubertal patients, semen analysis was performed. According to clinical data, results of testicular atrophy correlated with duration of symptoms and operative findings. In all cases of surgical detorsion in which torsion lasted more than 24 hours and viability of the testis was questionable, subsequent atrophy was the rule.
