Physiology of Lower Urinary Tract Obstruction

Urologic Clinics of North America, 1990
One of the major dilemmas facing pediatric urologists today is discerning obstruction in the dilated urinary tract.

Changing Concepts in Lower Urinary-Tract Obstruction in Children

JAMA, 1961
Making a voiding cystourethrogram prior to cystoscopy has been found to be of great value in the diagnosis of the site of obstruction of the lower urinary tract in children. Valvular obstruction of the posterior urethra was found to be more common than had been supposed. In the past 3 years 9 cases have been diagnosed.
