Abstract:
Objective To explore the pulsed wave Doppler (PWD) manifestations of acute experimental incomplete testicular torsion. Methods Eight healthy dogs were surgically modeled to obtain unilateral acute testis torsion from 180° to 630°, respectively. The peak systole velocity (PSV) and resistance index (RI) of intratesticular artery, capsular artery and arteria spermatica interna were measured with PWD before torsion, 2 h, 4 h and 6 h after torsion. Testes were examined pathologically after the experiment. Results PSV and RI of capsular artery and intratesticular artery decreased gradually with the extension of torsional time (P<0.05). PSV and RI of superior, torsional and inferior segments of arteria spermatica interna varied greatly and showed no strong regularity (P＞0.05) . The pathological results of testes showed no distinct changes or just mild interstitial hyperemia and edema. Conclusion The decrease of PSV and RI of capsular artery and intratesticular artery, especially RI have referential value in the judgement of acute experimental incomplete testicular torsion, whereas changes of PSV and RI of superior, torsional and inferior segments of arteria spermatica interna are not reliable.
