RATIONALE AND OBJECTIVES: To compare urethral stricture shear wave elastography (SWE) with normal areas and assess its association with other explanatory variables.
SUBJECTS AND METHODS: we recruited all men with urethral stricture disease referred to our center between December 2021 and July 2023. Patients underwent SWE and elasticity in the stricture area, and one and three centimeters distant from the stricture were measured. Gathered data were analyzed using Freidman and post hoc analysis, correlation methods, student t-tests, and one-way ANOVA.
RESULTS: 22 patients were recruited for our study. Spongiofibrosis was significantly higher in the stricture area relative to the one-centimeter-distant adjacent area (p < .0005), in the one-centimeter-distant compared to the three-centimeter-distant area (p = .002), and in the stricture area relative to the three-centimeter-distant area (p < .0005). There was no association between elasticity ratio and patient age or stricture location. Likewise, there was no difference in elasticity ratios between bulbar and pendulous strictures (p = 0.19) or among different etiologies of urethral strictures (p = 0.76).
CONCLUSION: There is a significant difference in elasticity between the urethral stricture area and other parts of the corpus spongiosum. Normal areas closer to strictures are stiffer. The elasticity ratio is unrelated to patient age or prior internal urethromies. Neither stricture locations nor distinct urethral stricture etiologies differed in elasticity ratios.
