Undescended Testis Surgery — Cost, Top Hospitals & Success Rates | MyMedicPlus

Undescended testis, medically known as cryptorchidism (from the Greek kryptos = hidden, orchis = testicle), is the most common congenital genitourinary anomaly in male infants. During normal fetal development, the testes form in the abdomen and descend through the inguinal canal into the scrotum by the 32nd week of gestation. In approximately 3% of full-term and up to 30% of premature male infants, one or both testes fail to complete this descent by birth.

While spontaneous descent may occur in the first few months of life — reducing the prevalence to approximately 1% by 6 months — testes that have not descended by 6 months are unlikely to do so spontaneously. Surgical correction (orchiopexy or orchidopexy) is the definitive and recommended treatment, ideally performed between 6 and 18 months of age. Early intervention is critical because prolonged exposure to abdominal temperature (1–2°C higher than scrotal temperature) causes progressive damage to germ cells responsible for future fertility, and increases the long-term risk of testicular malignancy.

Orchiopexy involves mobilising the undescended testis, freeing any anatomical obstructions, bringing the testis down into the scrotum, and securing it in a dartos muscle pouch. The procedure carries a high success rate (95–98%) and is generally well tolerated with a short recovery period. When performed within the recommended age window, it significantly preserves fertility potential and reduces the risk of testicular cancer, torsion, and associated psychological distress.

Undescended testis surgery addresses several anatomical variants and associated complications:

• Unilateral cryptorchidism: The most common presentation, where one testis (most often the right) fails to descend. Accounts for approximately 90% of all cases.
• Bilateral cryptorchidism: Both testes are undescended. Occurs in ~10% of cases and carries greater implications for fertility. Bilateral cases should be investigated for potential disorders of sexual differentiation.
• Ectopic testis: The testis has descended but migrated to an abnormal position outside the expected path — such as the perineum, femoral canal, or base of the penis — rather than the scrotum.
• Retractile testis: The testis can be manually guided into the scrotum but spontaneously retracts due to an overactive cremasteric reflex. While many cases resolve at puberty, those that ascend or become fixed require surgical fixation.
• Ascending (acquired) testis: A testis that was previously in the scrotum during infancy but has ascended due to a short spermatic cord or adhesions. More common than previously recognised.
• Testicular torsion risk: Undescended testes have an increased risk of torsion (twisting of the spermatic cord) due to inadequate fixation. Orchiopexy eliminates this risk.
• Associated inguinal hernia: A patent processus vaginalis is present in virtually all cases of cryptorchidism and is repaired at the time of orchiopexy.

Determining candidacy for orchiopexy involves assessing the child's age, testicular position, general health, and the presence of associated conditions:

• Optimal age window: Current guidelines from the European Association of Urology (EAU), American Urological Association (AUA), and Nordic consensus recommend surgery between 6 and 18 months of age. Earlier intervention is preferred within this range to protect germ cell development. Boys referred after the age of 6 months who have a non-palpable or undescended testis should be referred promptly.
• Premature infants: Surgical timing is adjusted using corrected gestational age. Many centres defer surgery until the infant reaches a corrected age of 6 months or a weight suitable for safe general anaesthesia.
• Older children and adolescents: Boys diagnosed later (school-age or puberty) should still undergo surgery, as it improves the ability to perform testicular self-examination and may reduce cancer risk, even if fertility benefit is diminished.
• Adults with late diagnosis: Adult males with a previously unrecognised undescended testis may undergo orchiopexy for fertility assessment, torsion prevention, or to facilitate surveillance for malignancy. Alternatively, orchiectomy (removal) may be recommended if the testis is atrophic or located high in the abdomen in post-pubertal males, particularly if the contralateral testis is normal.
• Failed hormonal therapy: hCG (human chorionic gonadotrophin) or GnRH analogue therapy has a modest success rate of 15–20% and is not recommended by most paediatric urology guidelines as first-line treatment. Surgical candidates include all children where hormonal treatment has failed or was not attempted.
• General anaesthesia fitness: The child must be medically fit for general anaesthesia. Pre-operative assessment addresses any cardiorespiratory concerns in premature infants.

The surgical approach depends on the location of the undescended testis, which is categorised as palpable (felt on examination, usually in the inguinal canal) or non-palpable (not felt, may be intra-abdominal, atrophic, or absent).

For Palpable Undescended Testes

• Standard open inguinal orchiopexy: The most common technique. A small incision is made in the inguinal (groin) crease. The testis and spermatic cord are mobilised from surrounding tissues, the processus vaginalis (hernia sac) is ligated, and the testis is brought into a dartos muscle pouch created in the scrotal skin. This technique is highly successful with minimal complications.
• Scrotal orchiopexy: For testes located at the external inguinal ring or just above, a single scrotal incision may be used. This approach is less widely adopted but is favoured in some centres for its cosmetic advantage and shorter operating time.

For Non-Palpable Undescended Testes

• Diagnostic laparoscopy: The first step for any non-palpable testis. A laparoscope is inserted through the umbilicus to visualise the abdominal cavity and determine whether the testis is present and its exact location.
• Single-stage laparoscopic orchiopexy: If the testis is intra-abdominal but close enough to the internal inguinal ring, the testis and its vessels can be mobilised laparoscopically and brought into the scrotum in one stage.
• Fowler-Stephens orchiopexy (two-stage): For high intra-abdominal testes with a short spermatic cord, the testicular artery is intentionally divided (first stage) to allow the testis to develop collateral blood supply through the vas deferens vessels. Six months later, the second stage brings the testis into the scrotum. This staged approach achieves a success rate of approximately 75–85%.

Adjuncts

• Hormonal therapy (GnRH/hCG): May be used as a neoadjuvant before surgery in some centres to improve vascularity, though evidence for improved fertility outcomes is limited.
• Testicular prosthesis: In cases of testicular atrophy or absent testis, a silicone prosthetic implant can be placed in the scrotum at a later age (usually puberty) for cosmetic and psychological benefit.

Timely surgical correction of cryptorchidism provides several clinically important benefits:

• Fertility preservation: The undescended testis undergoes progressive germ cell depletion due to supranormal temperature. Surgery before 12–18 months of age is associated with significantly better sperm counts and paternity rates compared with delayed surgery. For unilateral cases, paternity rates approach those of the general population when orchiopexy is performed early.
• Reduced testicular cancer risk: Men with a history of cryptorchidism have a 3–8 times higher risk of testicular germ cell tumour. While orchiopexy does not eliminate this risk, surgery performed before puberty reduces it significantly and, crucially, allows regular self-examination of the descended testis — a key tool for early cancer detection.
• Prevention of torsion: An undescended testis has inadequate natural fixation and is highly susceptible to torsion. Orchiopexy anchors the testis and eliminates this emergency risk.
• Hernia repair: The patent processus vaginalis invariably accompanying cryptorchidism is repaired simultaneously, preventing future inguinal hernia.
• Psychological and cosmetic benefit: An empty hemiscrotum in childhood and adolescence can cause significant psychological distress. Orchiopexy or prosthetic placement restores normal appearance and reduces self-consciousness.
• Facilitated surveillance: A scrotal testis can be monitored by the patient through self-examination and by clinicians through ultrasound, enabling early detection of any future pathology.

Orchiopexy is generally a safe procedure, but as with any surgery, complications can occur. Parents and patients should be counselled on the following:

• Anaesthetic risks: General anaesthesia in infants carries a small risk of respiratory or cardiovascular events. Modern paediatric anaesthetic techniques have made this extremely rare in otherwise healthy children.
• Testicular atrophy: The most significant complication, occurring in 1–3% of standard inguinal orchiopexies and up to 25% in two-stage Fowler-Stephens procedures. Vascular compromise during cord mobilisation can reduce blood flow to the testis, causing it to shrink or fail to survive.
• Vas deferens injury: The vas deferens (sperm-carrying tube) may be inadvertently damaged during dissection, particularly in the presence of adhesions. Injury to both vasa (in bilateral surgery) could affect future fertility.
• Wound infection: Superficial wound infections occur in fewer than 2% of cases and are usually managed with antibiotics.
• Haematoma or seroma: Collection of blood or fluid in the wound or scrotum may occur but usually resolves spontaneously.
• Recurrent undescent or migration: In a small proportion of cases the testis may re-ascend or not achieve a stable scrotal position, requiring revision surgery.
• Persistent infertility: Even with timely surgery, some degree of germ cell damage may already have occurred, particularly in bilateral cases, and fertility may be affected in adulthood.

Overall complication rates are low, and the benefits of surgery far outweigh the risks when performed by an experienced paediatric urologist or paediatric surgeon.

Recovery from orchiopexy is generally quick, especially when performed in infancy:

• Immediate post-operative period: Most cases are managed as day surgery or with one overnight stay. The child may experience mild pain and swelling in the groin and scrotum, managed with paracetamol (acetaminophen) or ibuprofen. An ice pack applied gently to the scrotum reduces swelling.
• Activity restrictions: Toddlers and infants require restricted physical activity for 1–2 weeks. Older children should avoid contact sports, rough play, and straddling activities (bicycles, climbing frames) for 4–6 weeks.
• Wound care: Dissolvable sutures are typically used and require no removal. The wound should be kept clean and dry for the first few days. Baths are usually permitted after 48 hours.
• First post-operative review: A clinic appointment at 6–8 weeks confirms testicular position, wound healing, and absence of complications.
• Long-term monitoring: Annual scrotal examination is recommended through childhood and adolescence to confirm the testis remains in position and is growing normally.
• Puberty and adulthood surveillance: At puberty, the patient should be taught testicular self-examination. Testicular ultrasound may be performed if there is any concern. Semen analysis may be offered in adulthood if fertility is a concern, particularly following bilateral orchiopexy.
• Cancer surveillance: Men with a history of cryptorchidism should maintain lifelong awareness of testicular cancer symptoms (painless lump, swelling, heaviness in the scrotum) and seek prompt medical review if any changes are noted.

The cost of undescended testis surgery varies considerably based on several factors:

• Surgical approach: Standard open inguinal orchiopexy is less expensive than laparoscopic or two-stage Fowler-Stephens orchiopexy, which requires additional equipment, longer operating time, and sometimes a second admission.
• Unilateral vs bilateral: Bilateral orchiopexy for both testes involves a longer surgical time and higher cost.
• Geographic location: Costs differ significantly by country. Approximate ranges (private, all-inclusive) include: India (USD 800–2,000), Thailand (USD 1,500–3,500), UK (GBP 2,500–5,000), USA (USD 5,000–15,000), Australia (AUD 3,000–7,000).
• Hospital tier: Tertiary paediatric hospitals with specialist paediatric urology teams may charge more than general surgical centres.
• Anaesthesia fees: Paediatric anaesthetists typically charge separately from the surgical team.
• Insurance coverage: In most countries with public healthcare systems (UK NHS, Canada, Australia Medicare), orchiopexy is fully covered. Private health insurance plans vary widely in their coverage of paediatric surgical procedures.
• Pre-operative investigations: Ultrasound, hormonal assays, or MRI for non-palpable testes add to the overall cost.

Families seeking treatment abroad should verify that the surgical team includes a paediatric urologist or paediatric surgeon with dedicated cryptorchidism experience, and confirm what aftercare is included in the package.

While orchiopexy is the recommended definitive treatment, the following alternatives or adjuncts are sometimes discussed:

• Hormonal therapy (hCG or GnRH analogue): Human chorionic gonadotrophin (hCG) injections or intranasal GnRH (buserelin) stimulate testosterone production and may occasionally prompt testicular descent. Success rates range from 15–25%, and are higher for lower-lying testes. However, the 2022 EAU Paediatric Urology Guidelines do not recommend hormonal treatment as a substitute for orchiopexy, citing limited efficacy and no proven benefit for long-term fertility or cancer risk reduction. It is not routinely offered in many countries.
• Watchful waiting (observation): Acceptable only in the first 6 months of life when spontaneous descent is still possible. Beyond 6 months, observation without a plan for surgical referral is not recommended by any major paediatric urology guideline, as delay worsens fertility and cancer outcomes.
• Orchiectomy (testicular removal): In post-pubertal males with a high intra-abdominal, atrophic, or contralateral normal testis, removal may be preferable to orchiopexy. The risk of malignancy in an atrophic intra-abdominal testis is significant, and the testis is unlikely to contribute to fertility.
• Testicular prosthesis (implant): A cosmetic option, not a treatment for cryptorchidism itself. Silicone prosthetics are placed in the scrotum (usually at puberty) when a testis is absent or has atrophied, restoring normal appearance and reducing psychological impact. They carry no fertility benefit.
