Posterior Urethral Valves (PUV)

ICD-10 Code
Q64.2

Obstructive developmental anomaly in male infants where membranous folds in the posterior urethra block urine outflow. Causes severe bilateral hydroureteronephrosis, bladder hypertrophy, and high risk of ESRD.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with [poor urinary stream / dribbling / abdominal distension / failure to thrive]. History significant for prenatal ultrasound findings of bilateral hydroureteronephrosis and thickened bladder wall. No history of UTI or febrile illness.

Clinical Examination Findings

Abdomen: Palpable bladder (distended), possible bilateral flank masses (hydronephrosis). Genitourinary: Weak, intermittent urinary stream, phimosis may be present. General: Signs of uremia or respiratory distress if pulmonary hypoplasia is present.

Treatment Protocol

Immediate management: Urinary decompression via urethral catheterization. Surgical intervention: Primary endoscopic valve ablation (fulguration). Long-term: Serial monitoring of renal function (Cr, BUN), renal ultrasound, and VCUG to assess for vesicoureteral reflux.
