The comparation of effects and security of double-J stent retention and ureteroscopy lithotripsy in the treatment of symptomatic ureteral calculi during pregnancy

Abstract

Objective: To describe the efficacy of double-J stent retention and ureteroscopy lithotripsy, we performed a study to evaluate the management of symptomatic ureteral calculi during pregnancy.

Materials and methods: From January 2005 and June 2015, 53 pregnant women with symptomatic ureteral calculi were admitted and treated in our hospital. According to the treatment techniques, there were divided into two groups: double-J stent retention group (30 cases) and ureteroscopy lithotripsy group (23 cases). We collected the characteristics and treatment outcome of the patients.

Results: Double-J stent retention was performed on 30 patients. And the stents were successfully inserted in 25 patients (83.3%). 4 cases got complication in double-J group (16%). The mean operating time, medical cost and hospitalization time of double-J group were 20.6 min, 1632 yuan and 1.3 days. Ureteroscopy lithotripsy was performed on 23 patients. 20 patients were operated successfully (87.0%). 2 cases got complication in ureteroscopy group (10.0%). The mean operating time, medical cost and hospitalization time of ureteroscopy group were 41.5 min, 2792 yuan and 6.0 days.

Conclusion: In summary, both double-J stent retention and ureteroscopy lithotripsy are effective and safe in the managation of ureteral calculi during pregnancy.
