In this episode, Dr. Suzette Sutherland and Dr. Alana Desai from the University of Washington discuss the management of urinary tract stones in pregnant patients, considerations for ureteroscopy, and consequences of radiation exposure in the fetus.

First, the doctors underscore the importance of ultrasound as the first line imaging modality to minimize fetal exposure to radiation. Dr. Sutherland and Dr. Desai also delve into nausea and pain management options, recommended diets for prevention of stone formation during pregnancy, and the necessity of involving a multidisciplinary team in such cases. The episode concludes with a remarkable case study from Dr. Desai’s experience.
