The urofacial syndrome is probably a subset of neurogenic bladder dysfunction syndromes characterized by detrusor-sphincter discoordination along with a characteristic inversion of facial expression with laughing. This characteristic facial expression can facilitate early detection of this disorder, which leads to poor bladder emptying with high residual urine, hydro-nephrosis with vesico-ureteral reflux and potentially renal failure if left untreated. The etiology of the urofacial syndrome is unknown. In our case, a 12-year-old boy of Middle-Eastern origin presented to the Outpatient Department of our hospital with left pyelonephritis, hydronephrosis and bladder dilatation. Voiding cystourethrography performed 15 days later revealed left vesicoureteral reflux. Cystoscopy revealed bladder trabeculation however an anatomic urethral obstruction was not noticed. Both, neurological examination and radiography of the lumbosacral spine were normal. Urodynamic evaluation revealed the typical findings of detrusor-sphincter discoordination.
