Prognosis of testicular torsion orchiopexy.

The purpose of this study was to follow up patients who underwent testicular torsion orchiopexies in order to observe whether testicular atrophy had occurred and to identify any influencing factors regarding atrophy. Patient data collected in this study included age, symptom duration, pre-operative preparation time, cryptorchidism testicular torsion, spermatic cord torsion degree, ultrasound findings at least 6 months after orchiopexy, testicular atrophy, mean platelet volume (MPV), address and medical insurance. Twenty-nine patients with a mean age of 147 (126.5-163) months involved in our study. The duration of follow-up ranged from 6 to 33 months with a median follow-up duration of 12 (8.5-21) months. Only MPV was significantly different between the atrophy group and nonatrophic group (p = .022) and the receiver operating characteristic (ROC) curve revealed that the cut-off value for MPV atrophy was 9.9 fl, with a sensitivity of 81.8% and a specificity of 70.6%. In conclusion, we found that 41.4% patients eventually experienced testicular atrophy after performing the testicular salvage procedure. MPV might be used as an indicator of testicular atrophy after an operation; however, the accuracy of MPV needs to be confirmed using significant follow-up prospective studies.
