Abstract

Abstract:

Objective

To investigate the diagnostic value of scrotal ultrasonography, testicular ischemia and suspicious torsion score (TWIST) system and peripheral blood platelet volume (MPV) in testicular torsion in children.

Methods

A retrospective analysis was performed on the case data of 150 children admitted to hospital due to pain and swelling of the scrotum from August 2020 to December 2024, according to the results of testicular exploration, 92 cases were in the testicular torsion group and 58 cases in the non-testicular torsion group. The diagnostic results of scrotal color Doppler ultrasound examination and testicular exploration were compared, the color ultrasound examination of scrotum, score of TWIST system at admission and peripheral blood MPV levels at the morning after admission were compared between the two groups. The multivariate logistic regression analysis was used to analyze the risk factors of testicular torsion in children, and the receiver operating curve (ROC) to analyze the diagnostic value of scrotal ultrasonography, TWIST score and MPV alone and in combination.

Results

The kappa consistency test between scrotal color Doppler ultrasound examination and testicular exploration was statistically significant (P<0.05). The testis volume, testicular bleeding grading (Arda grade) and TWIST system score were statistically significant differences between the two groups (P<0.05); the peripheral blood MPV levels in testicular torsion group was higher than that in the non-testicular torsion group (P<0.05). The multivariate logistic regression analysis showed that testicular volume, Arda grade, TWIST score and MPV were all risk factors for children with testicular torsion (P<0.05). ROC analysis showed that combined detection of testicular volume, Arda grade, TWIST score and MPV had higher diagnostic value for children with testicular torsion than single detection (P<0.05).

Conclusion

Scrotal color Doppler ultrasound has certain value in the diagnosis of testicular torsion. Combined with TWIST system score and MPV detection, it can further improve the diagnostic effect of testicular torsion in children.
