Kidney Stones in Pregnancy: Delivery Outcomes

National inpatient data show higher complication rates and longer hospital stays among pregnant patients with kidney stones.

Share

Pregnant patients with renal calculi experience significantly higher rates of labor and delivery complications and longer hospital stays compared to those without calculi. An analysis of over 698,000 delivery records in the US revealed that 85% of patients with renal stones faced complications, while only 29% of those without did. Factors such as insurance coverage and socioeconomic status influenced complication rates, with the study indicating that nearly 27% of the affected patients were from low-income areas. Renal stones are considered a common nonobstetric hospitalization cause during pregnancy due to physiological changes that increase the risk of symptomatic stone formation.
