Q64.4
Malformation of urachus
Clinical Classification Guidelines
Inclusion Terms
- Cyst of urachus
- Patent urachus
- Prolapse of urachus
Medical Intelligence & Overview
Malformation of the urachus encompasses a variety of congenital conditions involving the urachus, a tube-like structure connecting the fetal bladder to the umbilicus. Typically, the urachus obliterates before birth, transforming into a fibrous cord. However, in some cases, parts of this structure persist, leading to different anomalies such as urachal cysts, patent urachus, or prolapse of the urachus. These conditions can vary in presentation and severity, often requiring medical evaluation and management.
Causes & Symptoms
Clinical Causes: Incomplete or abnormal closure of the urachus during fetal development Genetic factors influencing fetal tissue development Intrauterine infections or other disturbances affecting embryonic development Environmental factors during pregnancy that might impact fetal tissue formation
Key Symptoms: Persistent or recurrent umbilical discharge, which may be cloudy or bloody Swelling or a palpable mass near the umbilicus Infection symptoms such as redness, warmth, or tenderness around the umbilical area Discomfort or pain in the lower abdomen or around the navel In cases of urachal cysts, intermittent swelling or drainage may occur without acute symptoms
Diagnostic & Treatment
Diagnosis Path: Ultrasound imaging to identify cysts, masses, or abnormal fluid collections Voiding cystourethrogram (VCUG) to examine the bladder and urachus for patency or leaks MRI or CT scans in some cases for detailed visualization of the urachal structures Clinical assessment of symptoms and physical examination findings
Treatment Protocols: Surgical removal of urachal cysts or diseased tissue to prevent recurrent infections and alleviate symptoms Drainage of abscesses or infected cysts in cases of infection Observation for asymptomatic patent urachus, with surgical intervention considered if symptoms develop Antibiotic therapy for infections associated with urachal anomalies
