Abstract

Purpose: Inadequate bladder emptying is a common urinary dysfunction in children. The role of α-blockers for managing bladder outlet obstruction remains relatively unexplored in children. Because of the well established impact of α-blocker therapy in men, we investigated its use for treating inadequate bladder emptying in the pediatric population. Materials and Methods: We treated 17 children 3 to 15 years old with documented poor bladder emptying of various etiologies, including dysfunctional voiding, the Hinman syndrome, the lazy bladder syndrome, posterior urethral valves, myelomeningocele and the prune-belly syndrome, using the α-1 adrenergic receptor antagonist, doxazosin. The initial dose of 0.5 to 1.0 mg. nightly was increased according to patient response and as tolerated. Patients were followed weekly to monthly by symptomatic history, and urine flow and/or post-void residual urine volume measurement. Two patients with neurogenic bladder were also followed with cystometrography and leak point pressure determination. Results: Bladder symptomatology and/or emptying improved in 14 patients (82%). Ten patients had decreased post-void residual urine during treatment and in 3 uroflowmetry showed increased maximum flow. Two patients with neuropathic bladder secondary to myelomeningocele had decreased leak point pressure on α-blocker therapy and in 2 with a history of posterior urethral valves new onset bilateral hydronephrosis completely resolved. Only 1 patient had mild postural hypotension, which resolved with dose reduction. Conclusions: Selective α-blocker therapy seems to be well tolerated in children and appears effective for improving bladder emptying in various pediatric voiding disorders at short-term followup. Long-term followup and further investigation are warranted to validate the potential role of α- blocker therapy in pediatric urinary dysfunction.
