Spontaneous resolution of urinary calculi in a congenital solitary kidney: A case report

Spontaneous resolution of a large renal stone burden in adults is a rare occurrence with few reports in the last 50 years. Improved imaging techniques and understanding of the pharmacology of dissolution therapy have led to a better understanding of which stones have the potential for spontaneous passage or targeted dissolution via medical treatment. Less is known regarding stone outcomes in children, and anecdotes of pediatric patients spontaneously passing large stones has been widely propagated. Here we report a case of spontaneous resolution of a large renal stone burden in a child with a congenital solitary kidney.
