RESUMEN
Hourglass bladder is a definition used to describe a particular configuration of the urinary bladder, divided into two compartments, upper and lower, communicating through a narrowed segment resembling an hourglass. It may be due to various conditions, such as bladder diverticula, bladder neck obstruction, neurogenic bladder, or other abnormalities. Congenital hourglass bladder is an extremely rare anomaly. To the best of our knowledge, only 24 cases have been reported. We present the case of a 2-year-old male, probably the youngest patient with congenital hourglass bladder ever recorded. We aim to increase knowledge about the incidence of this likely underdiagnosed condition and its management and stress the importance of long-term follow-up.
