Primary testicular lesions in the twisted testis

Area of Science:

• Urology
• Pathology
• Andrology

Background:

• Testicular torsion is a surgical emergency requiring prompt diagnosis and treatment.
• Understanding the underlying pathology of testicular torsion is crucial for improving patient outcomes.
• Primary testicular lesions may predispose individuals to torsion events.

Purpose of the Study:

• To investigate the presence and nature of primary lesions in testicular specimens from patients who experienced testicular torsion.
• To determine if these primary lesions contribute to the development of testicular torsion.

Main Methods:

• Histologic examination of 109 testicular biopsy and orchidectomy specimens from pubertal and adult males.
• Specimens were selected based on the known time of torsion and presence of seminiferous epithelium.
• Analysis focused on identifying primary lesions distinct from secondary anoxic damage.

Main Results:

• Primary tubular lesions were identified in 14% of the studied specimens.
• Observed lesions included focal hypospermatogenesis, hypoplastic zones with immature Sertoli cells, Sertoli-cell-only tubules, and intratubular calcifications.
• Multiple primary lesions were noted in some cases with severe anoxic damage.

Conclusions:

• A notable proportion of testicular torsion cases involve pre-existing primary testicular lesions.
• The actual prevalence of primary lesions may be underestimated due to limitations in specimen adequacy and anoxic artifact.
• These findings suggest that primary testicular abnormalities play a role in the pathogenesis of testicular torsion.
