Diagnostic and management considerations for nephrolithiasis in the gravid patient.

Renal colic is recognized as one of the most common causes of non-obstetric hospitalization during pregnancy. Furthermore, both symptomatic urolithiasis and its management have been associated with preterm labor, markedly amplifying the "typical" concerns of either pregnancy or stone passage alone. As those specializing in the care of stone disease are likely to be involved in the management of suspected renal colic in the pregnant woman, it is imperative to be informed of strategies and pitfalls in the evaluation and treatment of urinary tract stones in this population.
