Abstract:
Objective:To investigate the feasibility of shear wave elastography (SWE) to evaluate the protective effect of testicular compartment decompression on spermatogenesis after testicular torsion reduction.Methods:Thirty-two rabbits were randomly divided into 4 groups: control group (S group), testicular torsion simple reduction group (I group), and testicular torsion reduction+ compartment decompression group (T group: T1 group, T2 group), 8 rabbits per group. After the complete testicular torsion model was established in the I and T groups, the I group was simply reperfused, and the T group was reperfused before decompression of the compartment. Rabbits in each group were kept for 30 days after successful modeling. Each group of rabbits underwent testicular fascia intracompartment pressure measurement and SWE examination before operation, after successful complete torsion modeling, after reperfusion and 30 days later. After the experiment, the surgical side testicles were taken for pathological examination.Results:After testicular torsion, the pressure of testicular fascia and the average Young′s modulus (Emean) of testicular tissue in each experimental group increased (all P<0.05), and further increased with the extension of torsion time (all P<0.05). After reperfusion, the testicular fascial compartment pressure and testicular tissue Emean value in group I further increased (all P<0.05), while the testicular fascial compartment pressure and testicular tissue Emean value in group T decreased (all P<0.05). Thirty days later, testicular fascial compartment pressure and testicular tissue Emean value in group I were higher than those in group T (all P<0.05), while Johnsen′s score of testicular tissue was lower than that in group T ( P<0.05), and testicular tissue apoptosis index and malondialdehyde content were higher than those in group T Group T (all P<0.05). Conclusions:Decompression of the testicular compartment has a protective effect on spermatogenesis after testicular torsion reduction. SWE can indirectly evaluate the severity of testicular compartment syndrome after testicular torsion and reduction, and the protective effect of compartment decompression on spermatogenesis.
