Clinical classification for undescended testes: experience in 1,010 orchidopexies

Area of Science:

• Pediatric Surgery
• Urology
• Developmental Biology

Background:

• Undescended testes (cryptorchidism) affect male reproductive health.
• Accurate clinical classification is crucial for surgical planning and outcome prediction.

Purpose of the Study:

• To introduce and validate a clinical classification system for undescended testes based on location, size, and mobility.
• To correlate this classification with surgical findings and long-term outcomes in a large cohort.

Main Methods:

• A novel classification system categorizing testes by inguinal canal position (I-IV) and size (A-C) was developed.
• 1,010 orchidopexy procedures were performed using a uniform technique and followed annually for up to 23 years.
• Clinical diagnoses were compared with surgical findings.

Main Results:

• The classification system demonstrated good correlation between clinical and surgical findings.
• Normal-sized testes (A) were most frequent in lower positions (I), while smaller testes (B, C) were more common in higher positions (II-IV).
• Early surgery on well-sized testes in low positions resulted in simpler procedures and better outcomes.

Conclusions:

• The proposed classification system effectively categorizes undescended testes and predicts surgical outcomes.
• Early intervention is key for optimal results in managing cryptorchidism.
• Long-term cosmetic improvement was noted in surgically corrected testes of reduced volume (size B).
