Abstract：Objective: To explore the treatment of of urolithiasis in pregnancy. Methods: 51 pregnant women with urinary stone were given the benzene three phenol (40 mg, 2 times a day) firstly; if symptoms were not relieved, patients were treated with double J tube insertion or ureteroscopic lithotripsy under local anesthesia or continued epidural anesthesia. Results: Twenty-eight cases received conservative therapy which resulted in spontaneous stone expulsion. For patients failed to passage stone spontaneously, ten cases were performed double J tube insertion and 16 cases were performed ureteroscopic lithotripsy. There was no complication occurring associated to obstetrics and urology. Conclusions: It is advisable that conservative treatment is preferred to pregnancy associated with urinary calculi. if conservative treatment is invalid, the double J tube insertion or ureteroscopic holmium laser lithotripsy is also safe and effective.
