Undescended Testis Surgery is a specialized pediatric urologic procedure performed to relocate a testicle that has not moved properly into the scrotum. The condition, medically known as cryptorchidism, is one of the most common congenital abnormalities seen in male infants. If left untreated, it may affect fertility, hormone production, and long-term testicular health.
Today, modern surgical techniques allow safe and effective repositioning of the testis into the scrotum with excellent success rates. Moreover, early treatment significantly reduces the risk of complications and supports normal reproductive development.
What is an Undescended Testis?
An undescended testis occurs when one or both testicles fail to descend into the scrotum before birth. Normally, the testes develop inside the abdomen during fetal growth and gradually move down into the scrotum before delivery.
However, in some infants, this process remains incomplete. As a result, the testis may remain inside the abdomen, groin, or upper scrotal region. Consequently, the affected testis may not develop normally if treatment is delayed.
Types of Undescended Testis
Unilateral Undescended Testis
Only one testicle fails to descend. In fact, this is the most common form of cryptorchidism.
Bilateral Undescended Testis
Both testicles remain undescended. Therefore, the risk of fertility problems may become higher in the future.
Palpable Undescended Testis
The testis can be felt during physical examination, usually in the groin area. In such cases, surgery is generally more straightforward.
Non-Palpable Undescended Testis
The testis cannot be felt and may be located inside the abdomen or may sometimes be absent. Consequently, additional imaging or laparoscopy may be required.
Causes of Undescended Testis
The exact cause of cryptorchidism is not always known. Nevertheless, several developmental, hormonal, and genetic factors may contribute to the condition.
Possible Risk Factors
- Premature birth
- Low birth weight
- Family history of undescended testis
- Hormonal imbalance during pregnancy
- Genetic abnormalities
- Maternal smoking or alcohol exposure
Additionally, certain syndromes and developmental disorders may further increase the risk of undescended testes.
Symptoms of Undescended Testis
The primary sign is the absence of one or both testicles from the scrotum. In most cases, the condition is painless and noticed soon after birth.
Common Symptoms and Signs
- Empty scrotum on one or both sides
- Smaller scrotal sac
- Testis felt in the groin area
- Asymmetrical scrotal appearance
Sometimes, parents may notice the abnormality during bathing or diaper changes. Therefore, early pediatric evaluation is important.
Why is Undescended Testis Surgery Important?
Timely surgical correction is extremely important because untreated cryptorchidism may lead to several long-term complications.
Potential Complications Without Treatment
- Reduced fertility
- Increased risk of testicular cancer
- Testicular torsion
- Inguinal hernia
- Trauma to the undescended testis
- Psychological concerns related to appearance
Therefore, pediatric urologists strongly recommend early diagnosis and treatment. In addition, proper testicular positioning helps support normal hormonal and reproductive function.
Diagnosis of Undescended Testis
Diagnosis is usually made through physical examination by a pediatric urologist or pediatric surgeon. Furthermore, early assessment allows timely treatment planning.
Clinical Examination
The doctor evaluates:
- Position of the testis
- Scrotal development
- Presence of associated hernia
- Whether the testis is palpable
Imaging Tests
In selected cases, additional investigations may include:
- Ultrasound
- MRI scan
- Diagnostic laparoscopy
These tests help locate non-palpable testes and guide treatment planning more accurately. As a result, surgeons can select the most appropriate surgical technique.
What is Undescended Testis Surgery?
Undescended Testis Surgery, also called orchiopexy, is a procedure performed to move the testicle into the scrotum and secure it in the correct position.
The surgery helps preserve testicular function and supports normal growth and development. Furthermore, it improves cosmetic appearance and reduces future health risks.
Best Age for Undescended Testis Surgery
Early treatment is highly important for achieving the best outcomes.
Recommended Age
- Between 6 months and 18 months of age
Performing surgery at an early age helps improve fertility potential and reduces future complications. However, older children and adults may still benefit from corrective surgery when diagnosis is delayed.
Types of Undescended Testis Surgery
The surgical approach depends on the location and condition of the testis. Therefore, every patient requires individualized evaluation.
Open Orchiopexy
This procedure is commonly performed for palpable testes located in the groin.
Procedure Overview
- A small groin incision is made
- The testis is carefully mobilized
- The testis is placed inside the scrotum
- The testis is secured in position
As a result, the testicle remains stable inside the scrotum.
Laparoscopic Orchiopexy
This minimally invasive technique is used for non-palpable or abdominal testes.
Advantages
- Smaller incisions
- Better visualization
- Faster recovery
- Reduced postoperative discomfort
Moreover, laparoscopic surgery allows accurate identification of abdominal testes.
Two-Stage Fowler-Stephens Procedure
In complex abdominal cases, a staged approach may be required to safely relocate the testis. Consequently, this technique improves the chances of successful preservation.
Procedure of Undescended Testis Surgery
The surgery is performed under general anesthesia and is usually completed within one to two hours.
Preoperative Preparation
Before surgery, the child may undergo:
- Physical examination
- Blood investigations
- Anesthesia assessment
Additionally, parents receive detailed instructions regarding fasting and postoperative care.
Surgical Steps
Step 1: Administration of Anesthesia
General anesthesia ensures the child remains comfortable throughout the procedure.
Step 2: Identification of the Testis
The surgeon locates the undescended testis through open or laparoscopic techniques.
Step 3: Mobilization of the Testis
The testis and surrounding structures are carefully freed to allow proper positioning.
Step 4: Relocation into the Scrotum
The testis is gently moved into the scrotum. Subsequently, its blood supply is checked carefully.
Step 5: Fixation of the Testis
The testis is secured inside the scrotum to prevent retraction in the future.
Recovery After Undescended Testis Surgery
Most children recover quickly after orchiopexy. In fact, recovery is generally smooth with proper postoperative care.
Hospital Stay
- Many children are discharged the same day
- Some may require short observation
Recovery Timeline
First Few Days
Mild swelling and discomfort are common. However, symptoms usually improve rapidly within a few days.
Within 1–2 Weeks
Most children gradually return to normal activities. Nevertheless, strenuous activity should still be avoided.
Complete Healing
Full healing generally occurs within several weeks depending on the surgical technique used.
Parents are advised to avoid activities that may place pressure on the surgical area during recovery.
Postoperative Care After Orchiopexy
Proper care supports successful healing and minimizes complications.
Important Care Instructions
- Keep the surgical area clean
- Give prescribed medications regularly
- Avoid strenuous physical activity
- Attend follow-up appointments
- Monitor swelling or redness
Parents should contact the doctor immediately if fever, severe pain, or wound discharge develops.
