Urinary retention secondary to acute vasculitic penile swelling in a pediatric patient

Acute urinary retention secondary to vasculitic penile swelling in children is extremely rare. Henoch-Schönlein purpura is a self-limiting IgA-mediated cutaneous vasculitis, which can cause soft tissue edema. Acute urinary retention requires urgent intervention to prevent obstructive uropathy. Suprapubic catheterization provides an effective management strategy in the emergency setting.
