Laparoscopic Undescended Testis Surgery: Procedure, Instruments, Benefits & Recovery

Laparoscopic Undescended Testis Surgery: Procedure, Instruments, Benefits & Recovery

Laparoscopic Undescended Testis Surgery is a minimally invasive urological procedure used to locate and treat selected undescended testes, particularly when a testis cannot be felt during physical examination.

An undescended testis, medically known as cryptorchidism, occurs when one or both testes have not reached their normal position inside the scrotum. This condition is commonly identified during infancy and requires appropriate evaluation by a pediatric urologist or pediatric surgeon.

Laparoscopic orchiopexy, also called laparoscopic orchidopexy, aims to position a suitable undescended testis within the scrotum while preserving its blood supply and function where possible.

However, not every undescended testis requires laparoscopic surgery. The appropriate approach depends on the location of the testis, the child’s age, anatomical findings, and clinical assessment.

This JDMeditech guide explains laparoscopic undescended testis surgery, symptoms, diagnosis, treatment techniques, surgical instruments, benefits, complications, recovery, and frequently asked questions.

What Is an Undescended Testis?

An undescended testis is a testis that has not completed its normal descent into the scrotum.

During fetal development, the testes normally move from the abdomen toward the scrotum. However, this process may remain incomplete in some infants.

Consequently, a testis may remain within the abdomen, inguinal canal, or another location outside the scrotum.

Undescended testes may affect one side or both sides.

Furthermore, persistent cryptorchidism is associated with an increased risk of impaired fertility and testicular cancer later in life.

What Is Cryptorchidism?

Cryptorchidism is the medical term commonly used for undescended testes.

It is one of the most common congenital conditions affecting male infants.

Some testes descend naturally during the first few months after birth.

However, spontaneous descent becomes unlikely after approximately six months of corrected age.

Therefore, persistent undescended testes should be evaluated promptly by a qualified specialist.

Common Signs and Symptoms of Undescended Testis

• One or both testes are absent from the scrotum
• An underdeveloped or empty-looking side of the scrotum
• A testis that can be felt in the groin but not the scrotum
• Asymmetry in the scrotal appearance
• A testis that cannot be located during examination
• Occasional associated inguinal hernia

Most children with an undescended testis do not experience significant pain.

However, sudden groin or scrotal pain requires urgent medical assessment because testicular torsion or another acute condition may be present.

What Causes Undescended Testis?

The exact cause is not always identifiable.

However, several developmental and biological factors may contribute.

1. Premature Birth

Premature infants have a higher likelihood of undescended testes because testicular descent may not be complete before delivery.

2. Hormonal Factors

Hormonal signaling plays an important role in normal testicular descent. Disruption of these processes may contribute to cryptorchidism.

3. Genetic Factors

Some genetic and developmental conditions are associated with an increased risk of undescended testes.

4. Anatomical Abnormalities

Differences in the inguinal canal, gubernaculum, or related structures may interfere with normal testicular descent.

5. Low Birth Weight

Low birth weight is associated with an increased likelihood of cryptorchidism.

6. Acquired Testicular Ascent

In some children, a testis that was previously located in the scrotum may later ascend and become undescended.

Types of Undescended Testis

1. Palpable Undescended Testis

A palpable undescended testis can be felt during physical examination, often in the inguinal region.

These cases are commonly treated through an inguinal or scrotal surgical approach rather than laparoscopy.

2. Non-Palpable Undescended Testis

A non-palpable testis cannot be felt during examination.

It may be located inside the abdomen, within the inguinal canal, or may be absent or severely atrophic.

Diagnostic laparoscopy is particularly useful when a testis remains non-palpable under anesthesia.

3. Intra-Abdominal Testis

An intra-abdominal testis remains within the abdominal cavity rather than descending into the scrotum.

Selected intra-abdominal testes can be treated using laparoscopic orchiopexy.

4. Ectopic Testis

An ectopic testis lies outside the normal pathway of testicular descent.

Its treatment depends on the anatomical position and clinical findings.

5. Retractile Testis

A retractile testis can usually be moved into the scrotum during examination and remain there temporarily without tension.

Retractile testes generally do not require immediate surgery.

However, regular follow-up is recommended because secondary ascent can occur.

6. Ascending Testis

An ascending testis is a previously descended testis that later moves to a position outside the scrotum.

Specialist evaluation is required to determine appropriate treatment.

How Is Undescended Testis Diagnosed?

Diagnosis begins with medical history and careful physical examination.

The healthcare professional assesses the scrotum, inguinal region, and possible ectopic testicular locations.

Furthermore, the clinician determines whether the testis is palpable or non-palpable.

Routine ultrasound, CT, or MRI is generally not recommended before referral for an undescended testis because imaging cannot reliably confirm whether a non-palpable testis is present or absent.

For persistent non-palpable testes, examination under anesthesia and surgical exploration may be required.

In selected cases, diagnostic laparoscopy allows direct examination of the abdominal cavity.

Importantly, infants with bilateral non-palpable testes may require endocrinological and genetic evaluation for possible differences of sex development.

When Should Undescended Testis Surgery Be Performed?

According to pediatric urology guidelines, treatment should begin after approximately six months of corrected age if spontaneous descent has not occurred.

Orchiopexy is preferably completed between six and twelve months of age and by eighteen months at the latest.

However, children diagnosed later should still receive prompt specialist evaluation.

Early treatment may improve the opportunity to preserve future testicular function and reduce certain long-term risks.

What Is Laparoscopic Undescended Testis Surgery?

Laparoscopic Undescended Testis Surgery is a minimally invasive procedure used to locate and manage selected non-palpable or intra-abdominal testes.

The surgeon introduces a laparoscope through a small abdominal incision to visualize internal structures.

Depending on the findings, the surgical team may perform laparoscopic orchiopexy, a staged reconstructive procedure, or another appropriate intervention.

However, some patients require inguinal exploration instead of laparoscopic reconstruction.

What Is Laparoscopic Orchiopexy?

Laparoscopic Orchiopexy is a surgical procedure that aims to reposition an undescended intra-abdominal testis into the scrotum.

The surgeon evaluates the testis, its blood vessels, and the vas deferens before selecting the appropriate treatment.

When anatomy allows, a single-stage procedure may be performed.

However, a high intra-abdominal testis may require a staged procedure.

Types of Laparoscopic Undescended Testis Surgery

1. Diagnostic Laparoscopy

Diagnostic laparoscopy helps determine the location and condition of a non-palpable testis.

It may identify an intra-abdominal testis, spermatic vessels entering the inguinal canal, or blind-ending vessels consistent with a vanishing testis.

2. Single-Stage Laparoscopic Orchiopexy

Single-stage laparoscopic orchiopexy may be suitable when the testis can be repositioned into the scrotum without excessive tension on the spermatic vessels.

However, eligibility depends on the testicular position and vascular anatomy.

3. Fowler-Stephens Orchiopexy

Fowler-Stephens orchiopexy is a technique used for selected high intra-abdominal testes.

It relies on collateral blood supply when the primary testicular vessels cannot be preserved in the usual manner.

However, the technique carries a risk of testicular atrophy if the remaining blood supply is insufficient.

4. Two-Stage Fowler-Stephens Orchiopexy

In selected cases, surgeons perform Fowler-Stephens orchiopexy in two stages.

The interval between stages allows time for collateral blood supply to develop.

However, successful repositioning and preservation of testicular function are not guaranteed.

5. Laparoscopic Traction Orchiopexy

Selected high intra-abdominal testes may be managed using a staged traction technique, sometimes called the Shehata technique.

Unlike Fowler-Stephens orchiopexy, this approach aims to preserve the primary testicular vessels.

However, treatment selection depends on surgeon expertise and patient anatomy.

6. Orchiectomy in Selected Cases

Removal of a testis may be appropriate in selected situations, particularly when the testis is severely atrophic or when other clinical factors make preservation unsuitable.

However, the decision requires specialist assessment and is not routine for all undescended testes.

Laparoscopic Undescended Testis Instruments and Functions

How Is Laparoscopic Undescended Testis Surgery Performed?

A qualified pediatric urologist or pediatric surgeon performs the operation in an appropriately equipped hospital.

First, the healthcare team evaluates the child’s medical history, examination findings, and suitability for anesthesia.

Next, the surgeon may repeat the examination under general anesthesia.

If the testis remains non-palpable, laparoscopy may be used to locate it and assess the relevant anatomy.

Depending on the findings, the surgeon selects an appropriate surgical approach.

For a suitable intra-abdominal testis, the operation aims to reposition the testis within the scrotum while maintaining adequate blood supply.

However, a high intra-abdominal testis may require staged treatment.

Finally, the healthcare team completes the procedure and arranges postoperative monitoring and follow-up.

Potential Benefits of Laparoscopic Orchiopexy

1. Localization of Non-Palpable Testes

Laparoscopy allows direct assessment of selected intra-abdominal testes and related structures.

2. Minimally Invasive Access

Laparoscopy generally requires small abdominal incisions.

3. Appropriate Testicular Positioning

Successful orchiopexy aims to place a viable testis within the scrotum.

4. Preservation of Testicular Function

Early surgical treatment may improve the opportunity to preserve future testicular function.

5. Assessment of Testicular Anatomy

Laparoscopy allows the surgeon to evaluate the testis, spermatic vessels, and related anatomy.

6. Treatment Planning

Diagnostic laparoscopy can help determine whether single-stage, staged, or alternative management is appropriate.

7. Smaller Incisions

Minimally invasive access may reduce abdominal incision size compared with open abdominal exploration.

However, surgery does not guarantee normal fertility or eliminate future cancer risk.

Risks and Complications of Laparoscopic Undescended Testis Surgery

Laparoscopic orchiopexy is an invasive operation with potential complications.

• Bleeding
• Infection
• Testicular atrophy
• Testicular re-ascent
• Injury to the vas deferens
• Damage to testicular blood vessels
• Injury to nearby abdominal structures
• Postoperative swelling or hematoma
• Anesthesia-related complications
• Need for additional surgery

Testicular atrophy is an important risk, particularly in complex procedures involving high intra-abdominal testes.

Therefore, caregivers should discuss expected benefits, alternatives, and individual risks with the surgical team.

Recovery After Laparoscopic Undescended Testis Surgery

Recovery depends on the child’s age, surgical technique, and whether the procedure is completed in one or multiple stages.

Many uncomplicated orchiopexy procedures are performed as day-case operations.

However, some children require additional hospital observation.

Temporary discomfort, mild swelling, or bruising may occur around the surgical sites.

Children may gradually resume normal daily activities as advised by their surgeon.

However, strenuous activity, sports, or activities that put pressure on the surgical area may need to be restricted during healing.

Caregivers should follow the hospital’s individualized postoperative instructions.

Seek prompt medical assessment for fever, worsening pain, significant swelling, persistent bleeding, or other concerning symptoms.

Follow-Up After Laparoscopic Orchiopexy

Follow-up is important to assess testicular position, size, and postoperative healing.

The surgeon may evaluate whether the testis remains within the scrotum and whether there are signs of atrophy or re-ascent.

In selected cases, additional evaluation may be required.

Furthermore, patients with a history of undescended testes should receive appropriate counseling about long-term testicular health.

Undescended Testis and Future Fertility

Persistent undescended testes are associated with an increased risk of impaired fertility.

The risk is generally greater when both testes are affected.

Early orchiopexy may improve the potential for future fertility compared with delayed treatment.

However, surgery does not guarantee normal sperm production or fertility in adulthood.

Undescended Testis and Testicular Cancer Risk

Cryptorchidism is associated with an increased risk of testicular cancer later in life.

Early orchiopexy may reduce this risk compared with delayed correction.

However, surgery does not completely eliminate the increased risk.

Therefore, appropriate education and testicular self-examination after puberty are recommended.

How to Choose Laparoscopic Undescended Testis Surgical Instruments

Hospitals and pediatric urology departments should identify their clinical requirements before purchasing laparoscopic instruments.

First, confirm whether the planned procedure involves diagnostic laparoscopy, single-stage orchiopexy, or staged reconstruction.

Next, review the required laparoscope, trocar, grasper, dissector, and suturing instrument specifications.

Furthermore, confirm that instrument dimensions and equipment settings are suitable for pediatric patients.
