Abstract:
Objective To investigate the value of predicting testicular viability following unilateral testicular torsion by color-Doppler ultrasound (CDU). Methods The clinical manifestations, intraoperative findings and scrotol CDU appearances before and after operation of 42 cases with testicular torsion were compared. According to a bleeding test intraoperatively, testicular viability was divided into A-D level. Testis of level A-C would be saved .while the level D removed. Testicular viability assessed by follow-up CDU was then classed into Ⅰ-Ⅲ level. In Ⅰ-Ⅱ level, the salvaged testis were recovery ultimatelybut atrophy in level Ⅲ. Results Seventeen cases of the 42 underwent orchidopexy and the remaining 25 cases underwent orchidectomy. As followed up, however, testis in only 7 cases were recovered, including 2 cases in level A,3 cases in level B and 2 cases in level C. respectively. The preoperative scrotal CDU appearances of the recovered testis were mainly as follows: ① Homogeneous parenchyma with decreased or disappeared blood perfusion. ②Sheet or radial hypoechoic in the local testis but with preserved blood perfusion in most area else. Testis in the remaining 10 patients, including 8 cases in level C and 2 cases in level D, respectively, were atrophy finally. And large radial hypoechoic or diffuse inhomogeneous echo with none or a small amount of blood supply on the edge parenchyma were found during their preoperative CDU (similar CDU performance was present in the orchidectomy group. The CDU appearances of contralateral testes both in orchidopexy and orchidectomy group were not obviously abnormal during follow-up. Conclusions The scrotal CDU examination is competent to predict testicular viability after detorsion. In addition, timely operation would be a key to CDU evaluation.
