Torsion and the contralateral testicle.

J P York, J R Drago

    The Journal of Urology

    Summary
    This summary is machine-generated.

    Unilateral testicular torsion in rats causes damage to the contralateral testicle, but early detorsion or orchiectomy can prevent these effects. Late treatments are less effective, though some testicular function may be reversible.

    Area of Science:

    • Reproductive Medicine
    • Urology
    • Histopathology

    Background:

    • Testicular torsion is a urologic emergency requiring prompt intervention.
    • The contralateral testicle's response to unilateral torsion is not fully understood.
    • Histologic changes in the contralateral testis can impact fertility.

    Purpose of the Study:

    • To investigate the histologic effects of unilateral testicular torsion on the contralateral testis in adult rats.
    • To evaluate the efficacy of early versus late detorsion or orchiectomy in mitigating these effects.

    Main Methods:

    • Adult Noble rats underwent unilateral testicular torsion.
    • Contralateral testes were analyzed histologically after detorsion or orchiectomy at 3 hours (early) and 24 hours (late).
    • Histologic parameters included tubular spermatozoa, chromatin clumping, Sertoli cells, Sertoli cytoplasm, and germinal epithelium.

    Main Results:

    • Unilateral torsion induced loss of spermatozoa, chromatin clumping, Sertoli-only cells, and germinal epithelial sloughing in the contralateral testis.
    • Early detorsion or orchiectomy (3 hours) negated these adverse histologic changes.
    • Late detorsion (24 hours) did not reverse the effects, while late orchiectomy only partially mitigated them.
    • Depressed spermatogenesis and reduced tubular size were observed, but early spermatogenic elements suggest potential reversibility.

    Conclusions:

    • Unilateral testicular torsion significantly impacts the contralateral testis histologically.
    • Early surgical intervention (detorsion or orchiectomy) is crucial for preserving contralateral testicular integrity.
    • The potential for reversibility exists, underscoring the importance of timely treatment for testicular torsion.
