Managing stones in pregnancy: an update

The diagnosis of urinary calculi in pregnancy may be challenging, requiring a high index of clinical suspicion and judicious imaging selection. Investigations and intervention must be tailored not only to the pregnant patient's symptoms, but also the stage of pregnancy. A multidisciplinary team approach consisting of the perinatology team, urologist, interventional radiologist and anesthesiologist is required. Management should proceed from conservative to more invasive approaches. In the majority of cases, expectant management as first-line therapy will be successful. Temporizing measures or definitive intervention will be required in select circumstances.
