Surgical exploration for impalpable testes in children revealed a high rate of monorchism. Parents should be informed about the possibility of a vanishing testis or dysgenetic testis before surgery.

Area of Science:

  • Pediatric Surgery
  • Urology
  • Developmental Biology

Background:

  • Undescended testes are a common congenital anomaly in pediatric patients.
  • Unilateral impalpable testes require prompt diagnosis and management.
  • Surgical exploration is often necessary to determine testicular status.

Purpose of the Study:

  • To evaluate the surgical outcomes for children with unilateral impalpable testes.
  • To determine the incidence of testicular absence or dysgenesis in this cohort.
  • To inform pre-operative counseling regarding potential outcomes.

Main Methods:

  • Retrospective review of surgical cases involving unilateral impalpable testes.
  • Analysis of operative findings, including testicular presence, absence, or dysgenesis.

  • Calculation of the overall rate of monorchism.

    • Main Results:

    • Thirty children underwent surgical exploration for unilateral impalpable testes.
    • The testis was absent (vanishing testis) in 12 cases (40%).
    • Orchidectomy for dysgenetic testes was performed in 5 cases (16.7%), resulting in an overall monorchism rate of 56%.

    Conclusions:

    • A significant proportion of unilateral impalpable testes are either absent or dysgenetic.
    • The high rate of monorchism necessitates thorough pre-operative counseling for parents.
    • Informing parents about the potential for monorchism can manage expectations and improve shared decision-making.
