ICD-10: Q64.39

ICD-10 code Q64.39 refers to "Other atresia and stenosis of urethra and bladder neck," which is classified under congenital malformations of the urinary system. This code is used to document specific conditions where there is an abnormal narrowing (stenosis) or complete obstruction (atresia) of the urethra or bladder neck, which can significantly impact urinary function.

Clinical Description

Definition

• Atresia: This term describes a condition where a body orifice or passage is abnormally closed or absent. In the context of the urethra and bladder neck, it indicates a complete blockage that prevents urine from passing.
• Stenosis: This refers to the narrowing of a passage in the body. In this case, it affects the urethra or bladder neck, leading to difficulties in urination and potential complications.

Etiology

The causes of atresia and stenosis in the urethra and bladder neck can be varied, including:
- Congenital Factors: Many cases are present at birth due to developmental anomalies during fetal growth.
- Genetic Syndromes: Certain genetic conditions may predispose individuals to urinary tract malformations.
- Environmental Factors: Maternal exposure to certain drugs or toxins during pregnancy may contribute to the development of these conditions.

Symptoms

Patients with Q64.39 may exhibit a range of symptoms, including:
- Difficulty urinating or urinary retention
- Frequent urinary tract infections (UTIs)
- Abnormal urinary stream or incontinence
- Abdominal pain or discomfort

Diagnosis

Diagnosis typically involves:
- Imaging Studies: Ultrasound or MRI may be used to visualize the urinary tract and identify any obstructions or abnormalities.
- Urodynamic Testing: This assesses how well the bladder and urethra store and release urine, providing insight into functional issues.
- Cystoscopy: A direct visual examination of the urethra and bladder using a thin tube with a camera can help confirm the diagnosis.

Treatment Options

Surgical Intervention

The primary treatment for atresia and stenosis often involves surgical procedures aimed at:
