Abstract
Congenital bladder anomalies are rare, encompass a broad spectrum of disorders, and may confer risk to the upper urinary tract. Urachal remnants are the result of failure or delay in obliteration of the allantois and often present as umbilical drainage in the neonatal period. Posterior urethral valves are the most common cause of lower urinary tract obstruction in boys and are detected due to prenatal hydronephrosis, oligohydramnios, and/or a thick-walled bladder. Prune belly syndrome is characterized by deficient or absent abdominal wall musculature, bilateral intraabdominal cryptorchidism, and urinary tract anomalies. The bladder exstrophy-epispadias complex is a rare malformation with lower abdominal wall defect exposing an open bladder and urethra, wide diastasis of pubic symphysis, anorectal anomalies, and epispadic urethral opening. Spina bifida is the most common congenital cause of neurogenic bladder and is characterized by varying severities of spinal cord defects resulting in a spectrum of detrimental effects on the somatic, sympathetic, and parasympathetic nervous system of the urinary tract. While the incidence of congenital bladder anomalies is low, functional disorders of the lower urinary tract are quite common and include abnormalities in bladder filling and/or emptying and are often associated with constipation.
