Surgical Management of Cryptorchidism

Definition and Purpose

  • The American Urological Association recommends orchidopexy as the standard surgical treatment for cryptorchidism to preserve fertility potential and reduce cancer risk, and should be performed by 18 months of age 1, 2
  • The primary goals of orchidopexy are preservation of fertility potential 1, 3, reduction of testicular cancer risk 3, 4, and improved testicular monitoring for future cancer surveillance 3

Timing of Intervention

  • The optimal timing for surgery is by 18 months of age, as progressive histologic damage occurs to undescended testes, particularly after the first year of life 1, 2, 4
  • Infants with cryptorchidism at birth should be referred if no spontaneous descent by 6 months, and boys diagnosed after 6 months should be promptly referred to a surgical specialist 5

Surgical Techniques

  • The standard inguinal orchidopexy is indicated for most palpable undescended testes 1
  • Laparoscopic orchidopexy is indicated for non-palpable testes and allows for diagnosis and treatment in the same procedure 1, 3

Management of Non-Palpable Testes

  • The identification of testicular vessels is the primary objective during exploration, and the surgical approach depends on findings 1, 3

Special Considerations

  • Orchiectomy may be appropriate when very short testicular vessels and vas deferens are present, or when the testis is dysmorphic or hypoplastic 1, 3

Outcomes and Prognosis

  • The overall success rate for open surgical intervention is >96%, with a testicular atrophy risk of <2% 1
  • Cryptorchidism increases testicular cancer risk by 2.75-8 times, but prepubertal orchidopexy reduces this risk by 2-6 fold compared to postpubertal surgery 1, 3
  • Unilateral cryptorchidism has paternity rates similar to the general population, while bilateral cryptorchidism has significantly reduced fertility 3, 6

Post-Operative Follow-up

  • Regular monitoring of testicular position and development is necessary throughout childhood and adolescence, and patient education should include counseling on long-term risks of infertility and cancer 3, 5

Management of Undescended Testis with Concomitant Indirect Inguinal Hernia in Pediatric Patients

Primary Recommendation

  • The American Academy of Pediatrics recommends performing concurrent orchiopexy and inguinal hernia repair in a single operation once the infant reaches 6 months of corrected gestational age, with surgery completed by 18 months of age 7

Timing of Surgical Intervention

  • The American Academy of Pediatrics suggests deferring surgery until 6 months of corrected gestational age to allow for potential spontaneous testicular descent, even when an inguinal hernia is present 7
  • Testes that remain undescended by 6 months are unlikely to descend spontaneously and require surgical referral, according to the American Academy of Pediatrics 7
  • All orchiopexy procedures must be completed by 18 months of age to preserve fertility potential, as progressive germ cell loss accelerates after 15-18 months, as recommended by the American Urological Association 7

Surgical Approach Selection

  • The American Academy of Pediatrics recommends standard inguinal orchiopexy with concurrent hernia repair as the gold standard approach, with success rates exceeding 96% and testicular atrophy rates below 2% 8
  • The inguinal approach allows simultaneous mobilization of the spermatic cord, closure of the patent processus vaginalis (hernia repair), and placement of the testis into a scrotal dartos pouch, according to the American Academy of Pediatrics 8

Management of Concurrent Hernia

  • The American Academy of Pediatrics states that all inguinal hernias in pediatric patients with undescended testes represent a patent processus vaginalis that must be addressed surgically 8
  • The processus vaginalis should be ligated at the internal ring during orchiopexy, as recommended by the American Academy of Pediatrics 8
  • More than 90% of pediatric inguinal hernias occur in boys due to the relationship between testicular descent and processus vaginalis formation, according to the American Academy of Pediatrics 8

Optimal Timing and Surgical Management of Undescended Testis (Orchidopexy)

Timing of Surgery

  • Orchidopexy should be completed by 18 months of age, with the optimal window between 6 months and 18 months corrected gestational age, to preserve future fertility potential. 9
  • Germ‑cell degeneration accelerates after 15–18 months; approximately 40 % of boys with bilateral undescended testes lack germ cells by 8–11 years if left untreated. 9
  • Systematic‑review evidence indicates that performing orchidopexy between 6 months and 12 months maximizes fertility outcomes and reduces the risk of testicular cancer. 9
  • Even when diagnosis occurs later in the prepubertal period (up to 18 months), orchidopexy still confers clear benefits compared with no surgery. 9

Preoperative Assessment

  • For non‑palpable testes, laparoscopic exploration is mandatory because radiologic imaging (ultrasound, CT, MRI) lacks sufficient sensitivity and specificity. 9
  • The primary goal of laparoscopic exploration is to assess the status of the testicular vessels, which determines whether orchidopexy or orchiectomy is feasible. 9
  • Among non‑palpable testes, roughly 55 % are intra‑abdominal, 30 % are located in the inguinal‑scrotal region, and 15 % are absent or “vanishing.” 9

Surgical Technique Selection

  • For low‑lying palpable testes, a single‑incision scrotal orchidopexy is as effective as the traditional two‑incision inguinal approach. 9
  • Laparoscopic orchidopexy for non‑palpable testes achieves success rates of 85–90 %. 9

Post‑Operative Outcomes and Complications

  • Testicular atrophy occurs in fewer than 2 % of orchidopexy cases. 9
  • Testicular re‑ascent is observed in approximately 4–5 % of cases and may necessitate repeat surgery. 9

Long‑Term Cancer Risk

  • After successful orchidopexy, the risk of testicular cancer remains 2.75–8 times higher than baseline; however, surgery performed in the prepubertal period reduces this risk by 2–6 fold compared with correction after puberty. 9

Hormonal Therapy and Imaging Recommendations

  • Primary hormonal therapy with hCG or GnRH shows low efficacy (6–38 % success in controlled studies) and carries a high recurrence risk; it is not recommended as the main treatment. 9
  • Imaging modalities (ultrasound, CT, MRI) should not be used to locate non‑palpable testes because of inadequate diagnostic performance; direct laparoscopic exploration is advised. 9
  • Informed consent should explicitly mention a 2–5 % chance of testicular re‑ascent requiring a second operation. 9
  • Families should be counseled that, despite orchidopexy, the long‑term cancer risk remains elevated and that regular testicular self‑examination after puberty is essential for early detection. (Cancer‑risk data cited above.) 9
