Insights
Posterior urethral valves (PUV) are a common cause of urinary obstruction in boys. Early diagnosis with bedside sonography can expedite care and prevent progression to end-stage renal disease.
Area of Science:
- Pediatric Urology
- Medical Imaging
Background:
- Posterior urethral valves (PUV) represent the most frequent cause of urinary tract obstruction in male pediatric patients.
- Clinical manifestations of PUV outside the neonatal period are diverse, including urinary tract infections, abdominal masses, renal failure, and voiding dysfunction.
Abstract:
Posterior urethral valves are the most common cause of urinary obstruction in male children. Presentations of posterior urethral valves beyond the neonatal period include urinary tract infection, abdominal mass, renal failure,diminished urinary stream, crying during micturition,incontinence, dysuria, hematuria, or failure to thrive. Early diagnosis is imperative because early surgical relief of the obstruction is believed to help prevent the progression to endstage renal disease.This case serves to remind us that, in the male child who presents with urinary symptoms and/or abdominal symptoms,the bedside sonogram is a valuable tool that can clarify the diagnosis and expedite care.
