Surgical Management of Undescended Testis

Primary Recommendation

The American Academy of Pediatrics and European Urology recommend orchidopexy as the standard surgical procedure for undescended testis, which should be performed by 18 months of age to preserve fertility potential and reduce cancer risk 1

Prepubertal orchidopexy reduces testicular cancer risk by 2-6 fold compared to postpubertal surgery in patients with undescended testis, with open surgical orchidopexy achieving >96% success rates and <2% risk of testicular atrophy 2, 1
The European Urology guidelines suggest performing orchidopexy at diagnosis once the child reaches 6 months of age, as progressive germ cell degeneration occurs after the first year of life and worsens during the second year 3, 1

Standard inguinal orchidopexy is the primary approach for most palpable undescended testes, according to the American Urological Association 1

Orchiectomy should be performed when a normal contralateral testis is present and there are very short testicular vessels and vas deferens, dysmorphic or severely hypoplastic testis, or postpubertal age, as recommended by the American Urological Association 2, 4

The European Urology guidelines advise against using hormonal treatment for cryptorchidism in postpubertal men, as it is ineffective 3
Delaying surgery beyond 18 months in prepubertal boys should be avoided, as progressive histologic damage continues with delayed treatment, according to the European Urology and American Academy of Pediatrics guidelines 3, 1

Testicular cancer risk remains elevated 2.75-8 times baseline despite orchidopexy, and patients should be taught monthly testicular self-examination after puberty for early cancer detection, as recommended by the American Cancer Society and European Urology 2, 1
Unilateral cryptorchidism has near-normal paternity rates, while bilateral cryptorchidism significantly reduces fertility to 35-53%, according to the American Society for Reproductive Medicine and European Urology 5, 6

Spontaneous descent is extremely unlikely after 6 months of corrected age, and this child is well beyond that window, with a high likelihood of requiring surgical intervention, as recommended by the American Urological Association 7, 8
The American Urological Association guidelines explicitly state that referral should occur by 6 months, with surgery by 18 months, to preserve fertility potential and reduce testicular cancer risk 7, 8

Approximately 70% of undescended testes are palpable and require standard inguinal orchiopexy, not laparoscopy, with a high success rate, as reported by the American Urological Association 7, 8
If the testis is non-palpable, laparoscopy becomes mandatory to identify testicular vessel status and determine surgical approach, with approximately 30% of testes located in the inguinal-scrotal area, 55% intra-abdominal, and 15% absent/vanishing 7, 8
