Management of urolithiasis in pregnancy

Michelle Jo Semins,1 Brian R Matlaga21University of Pittsburgh Medical Center, Pittsburgh, PA, USA; 2Johns Hopkins Medical Institutions, Baltimore, MD, USAAbstract: Kidney stones are very common and unfortunately do not spare the pregnant population. Anatomical and pathophysiological changes occur in the pregnant female that alter the risk for development of nephrolithiasis. Acute renal colic during pregnancy is associated with significant potential risks to both mother and fetus. Diagnosis is often challenging because good imaging options without radiation use are limited. Management of diagnosed nephrolithiasis is unique in the pregnant population and requires multi-disciplinary care. Herein, we review the metabolic alterations during pregnancy that may promote kidney stone formation, the complications associated with acute renal colic in the pregnant state, and our proposed diagnostic and management algorithms when dealing with this clinical scenario.Keywords: kidney stones, nephrolithiasis, pregnancy
