Objective: Young males with lichen sclerosus (LS) commonly present with phimosis; complete urinary obstruction has also been described in this population, but is much rarer. We present the case report of a boy with acute renal failure secondary to urethral obstruction caused by LS, with a review of the literature regarding the occurrence of complete urinary obstruction and renal failure associated with this disease process.
Materials And Methods: A comprehensive review of the literature was conducted using MEDLINE and EMBASE to characterize the association of lichen sclerosus with significant obstructive complications of the urinary tract.
