Summary

A novel classification system for undescended testis (UDT) categorizes it into congenital and acquired forms. This framework aids in clinical management and treatment decisions for UDT.

Acquired undescended testes and fertility potential: is orchiopexy at diagnosis better than awaiting spontaneous descent?

Andrology·2015

Area of Science:

  • Pediatric Surgery
  • Urology
  • Developmental Biology

Background:

  • Undescended testis (UDT) is a common congenital anomaly requiring precise classification for effective management.
  • Existing classifications may lack clinical applicability, necessitating a refined system.

Purpose of the Study:

  • To propose a new, clinically applicable classification system for undescended testis (UDT).
  • To differentiate between congenital and acquired forms of UDT for tailored treatment strategies.

Main Methods:

  • The study introduces a classification system categorizing UDT into congenital (intra-abdominal, intra-canalicular, supra-scrotal, ectopic) and acquired (primary: ascending, high scrotal; secondary: trapped testes) forms.
  • Clinical criteria are used to define and differentiate these categories.

Main Results:

  • Congenital UDT requires early surgical intervention, ideally by 1 year of age.
  • Acquired UDT presents primary (ascending, high scrotal) and secondary (trapped testes) subtypes, with treatment approaches varying.
  • Therapeutic options for primary acquired UDT include orchidopexy, hormonal therapy (human chorionic gonadotrophin), or a 'laissez faire' policy, while secondary acquired UDT is best managed surgically.

Conclusions:

  • The proposed classification provides a structured approach to UDT diagnosis and management in clinical practice.
  • Early surgical treatment is recommended for congenital UDT.
  • Management of acquired UDT, particularly primary forms, requires careful consideration of therapeutic options, with surgery favored for secondary acquired UDT.
