Abstract:
Objective:To explore the value of contrast enhanced ultrasonography(CEUS) combined with shear wave elastography (SWE) in the diagnosis of urethral stricture.Methods:One hundred and twenty patients with urethral stricture were recruited, and preoperative retrograde urography, common urethral ultrasound, and CEUS were used to measure the length of the stricture site, and SWE was used to detect the elasticity value of the stricture site and its nearby spongiosum. Intraoperative urethral stricture lesion site measurements were performed to confirm the actual lesion location and length during surgery and to compare them with the lengths measured in the preoperative examination;4 months after surgery, SWE was used to detect the stiffness of the surgical site and to assess the surgical efficacy and prognosis.Results:The stenosis length measured by CEUS and intraoperative measurement had no statistical difference: (4.41 ± 1.47) cm vs. (4.37 ± 1.36) cm, t = 0.22, P>0.05. The elastic value in urethra stenosis in SWE was higher than that in normal urethra: (33.1 ± 6.7) kPa vs. (23.3 ± 4.1) kPa, there was statistical difference ( t = 13.67, P<0.05). The elastic value of unobstructed urethra and that of normal urethra after reconstruction had no statistical difference ( t = 0.95, P>0.05). Conclusions:CEUS combined with SWE is a safe, accurate and effective method to evaluate urethral stricture. SWE can be used to measure postoperative outcomes and recurrence.
