Extracorporeal shock wave lithotripsy of renal calculi during early pregnancy.
OBJECTIVE
To evaluate the safety of renal stone treatment by extracorporeal shock wave lithotripsy (ESWL) during pregnancy.


METHODS
Data from 824 women of reproductive age who were treated by ESWL were analysed and the patients surveyed using a questionnaire about pregnancies, to which 636 (76%) responded. Of these patients, six had inadvertently undergone ESWL for renal stones during the first month of pregnancy. The stones were detected and located during ESWL using ultrasonography.


RESULTS
The six patients gave birth to six children who had no detectable malformations or chromosomal anomalies.


CONCLUSIONS
Although these results suggest that there were no adverse effects of ESWL during early pregnancy, a larger series should be assessed to confirm the safety and long-term effects of ultrasound-guided ESWL in the treatment of renal calculi during pregnancy. We do not advocate lithotripsy as a treatment for renal calculi in pregnancy, but inadvertent lithotripsy in a pregnant woman is not a cause for concern.
