Treatment of Symptomatic Ureteral Calculi during Pregnancy / 中国医科大学学报

ABSTRACT

Objective To present our experience with the management of symptomatic ureteral calculi during pregnancy and to compare the effi?cacy of two treatmentsdouble?J stent insertion and ureteroscopy. Methods In a retrospective study between January 2007 and January 2015,38 pregnant women were treated for symptomatic ureteral calculi in our hospital. The patients were divided into two groups based on whether they re?ceived double?J stent insertion(n=21)or ureteroscopic lithotripsy(n=17). We collected and compared the patients 'characteristics and treat?ment outcomes,such as success ratio,rate of complications,surgical time,medical costs,and hospitalization time. Results In the double?J group, the insertion of a double?J stent was possible for 17 of 21 patients(success rate,81.0%). In the ureteroscopy group,15 of 17 patients had complete calculi fragmentation(success rate,88.2%). Complications in the double?J stent retention group were slightly higher than in the ureteroscopic litho?tripsy group. The medical costs and hospitalization time required to perform ureteroscopic lithotripsy were significantly higher compared to double?J stent insertion. Patients in the double?J group contended with stones after delivery. Conclusion Both of double?J stent insertion and ureteroscopic lithotripsy are effective for the treatment of symptomatic ureteral calculi during pregnancy. The success rate of ureteroscopy ,which can directly dis?rupt stones,was higher. However,double?J stent insertion costs less and is simple and convenient. The technique that is chosen to be performed de?pends on the patient's practical situation and personal preference.
