Q53.1 Undescended testicle, unilateral

Name of the Condition

• Undescended testicle, unilateral

Summary

Undescended testicle, unilateral is a condition where one testicle fails to descend into the scrotum before birth. This is a common congenital condition in male infants and may resolve spontaneously within the first few months of life.

Causes

The exact cause of an undescended testicle is not fully understood, but it may involve hormonal, genetic, or environmental factors that disrupt normal testicular development and migration during fetal growth.

Risk Factors

• Preterm birth
• Low birth weight
• Family history of undescended testicles
• Certain genetic conditions or abdominal wall defects

Symptoms

• One testicle is not palpable in the scrotum.
• Asymmetry of the scrotum.
• In some cases, no additional symptoms are present, but discomfort or pain may occur.

Diagnosis

Physical examination is the primary method to identify the undescended testicle. If the testicle is not palpable, imaging such as ultrasound or MRI may be used to locate it.

Treatment Options

• Watchful waiting: Often recommended in the first few months as spontaneous descent may occur.
• Hormone therapy: Occasionally used to stimulate testicular descent.
• Orchiopexy surgery: A surgical procedure to move the undescended testicle into the scrotum, typically performed after six months if descent has not occurred naturally.

Prognosis and Follow-Up

The prognosis is generally good with timely treatment. Regular follow-up is important to monitor testicular development and function, especially for fertility and cancer risk.

Complications

• Increased risk of testicular torsion.
• Higher likelihood of infertility if left untreated.
• Slightly elevated risk of testicular cancer later in life.

Lifestyle & Prevention

No specific lifestyle changes can prevent this condition, as it is congenital. Early detection and follow-up care are key to managing potential complications.

When to Seek Professional Help

Consult a healthcare provider if a testicle is not palpable in the scrotum after birth, or if there is pain, swelling, or other concerning symptoms.

Tips for Medical Coders

Document the laterality (unilateral) and confirm the absence of other specified locations (e.g., inguinal, perineal) to ensure accurate coding. Include details of any imaging or surgical interventions if performed.
