Abstract:
Objective To systematically evaluate the optimal indwelling time of double?J stent in the treatment of ureteral complicated calculi post?ureteroscopy. Methods A total of 161 patients with complicated ureteral calculi were enrolled in this study from August 2012 to August 2015. All patients received the treatment of ureteroscopic holmium YAG Laser lithotripsy and were randomly divided into 3 groups according to varied double?J stent indwelling time: group A < 2 weeks (n = 43),group B from 2 ~ 6 weeks(n = 67),and group C>6 weeks (n = 51). Complications of three groups were compared and the hydronephrosis after removing double?J stent was recorded. Results The rate of complications of group C was significantly higher than that in group A and group B (P<0.017). However,group A(10/43)has a higher rate of ureterostenosis after removing double?J stent compared with group B(4/67)and group C(3/51),while no statistical significance was observed between group B and group C. Conclusion The incidence of complications after lithotripsy increased with the indwelling time of double?J stent,but the short indwelling time would led to ureterostenosis. Therefore,the optimal indwelling time of double?J stent after flexible ureteroscopy was 2 to 6 weeks,and the indwelling time for patients with injury ureteral mucosa could be appropriately prolonged.
