Application of translabial ultrasound in female periurethral benign solid lesions / 中华超声影像学杂志

ABSTRACT

Objective:To investigate the value of translabial ultrasound (TLUS) in female periurethral benign solid lesions (PBSL).Methods:Twenty-one female patients (21 lesions) with PBSL identified pathologically within the process of cystoscope or surgery from June 2017 to December 2020 were enrolled. All of them underwent urethral examination (UE) and TLUS. The detection rates of the lesions of UE and TLUS were compared, and the ultrasonic diagnostic accuracy and ultrasonic manifestations were analyzed.Results:Sixteen of the 21 patients showed lower urinary tract symptoms (76.19%). Among the 21 lesions, the detection rates of UE and TLUS were 52.38% (11/21) and 85.71% (18/21), respectively, the difference was statistically significant ( P=0.019). The length of 18 lesions detected by TLUS was (1.79±1.04)cm, and 13 lesions (72.22%) were shorter than 3 cm. Among 18 cases, urethral caruncle (13 cases) was the most common benign periurethral mass, the main ultrasonic manifestations of urethral caruncle showed hyperecho lesions in the middle and distal urethra, and the blood flow was mostly in a branch-like distribution. At the same time, there were 5 cases of urethral myoma and other solid lesions, the main ultrasonic manifestations of urethral myoma showed clear boundary, low echo and peripheral short strip blood flow. Using pathological results as the gold standard, the accuracy of ultrasonic diagnosis was 88.89% (16/18). Conclusions:TLUS is able to improve the detection rate of periurethral benign solid lesions, and the diagnostic concordant rate is acceptable.TLUS can provide more diagnostic and therapeutic information.
