Abstract

Abstract: Objective To investigate the clinical value of color Doppler ultrasound (CDU) in the early diagnosis of testicular torsion and postoperative vitality prediction.Methods Fifty patients with testicular torsion were diagnosed by color Doppler ultrasound before operation to determine the maximum diameter, peak systolic velocity (PSV), and resistance index (RI) of both affected and normal testicles, and to divide the preoperative vitality of affected testicles into 1-4 levels according to the ultrasound manifestations and blood flow supply.Operation Methods were determined according to the preoperative vitality of testicles.According to the testicular volume ratio (C) and CDU results, the postoperative vitality of testicles was divided into A-C level, A-B levels indicating testicular survival and C-level indicating testicular atrophy.Results The ultrasound diagnosis Results of 45 cases were consistent with the Results of operation, with an accuracy rate of 90%.The maximum diameter of the affected testicles [(5.2±1.2) cm] was larger than that of the normal testicles [(3.6±0.6) cm], the PSV of the affected testicles [(2.9±1.9) cm/s] was higher than that of the normal testicles [(7.8±2.2) cm/s], and the RI of the affected testicles (0.69±0.06) was higher than the normal testicles (0.48±0.03,P<0.05).Respectively 5 cases received testicular torsion resection and 40 cases retained testicles by testicular torsion reduction.There were 20 cases with A level vitality of testicles, whose preoperative vitality of testicles were graded into level 1 (n=8), level 2 (n=10), and level 3 (n=2); 17 cases with B level vitality of testicles, whose preoperative vitality of testicles were graded in to level 2 (n=1) and level 3 (n=16); and 3 cases with C level vitality of testicles, whose preoperative vitality of testicles were graded into level 3 (n=2) and level 4 (n=1).There was a significant correlation between the preoperative vitality of testicles and the postoperative follow-up vitality of testicles (r=0.824, P<0.001).Conclusion CDU is highly sensitive and specific to the early diagnosis of testicular torsion, and has important value in predicting the vitality of torsional testis after reduction.
