Abstract:
Objective To explore the optimum time of removal of preoperative double J stent before adjuvant radiotherapy in cervical cancer. Meth?ods A total of 90 patients with cervical cancer who underwent radical surgery between January 2014 and March 2015 were retrospectively analyzed. In addition,these recruited patients also underwent preoperative placement of double J stent and had them removed before the adjuvant radiotherapy. The patients were then divided into three groups based on the time of removal of double J stent. Group A(n=21)had the stent removed 2 to 4 weeks after the surgery;group B(n=46)had the stent removed 4 to 5 weeks after the surgery;group C(n=23)had the stent removed greater than or equal to 5 weeks after the surgery. The complications caused by stent placement and their improvement after stent removal were compared among the three groups. Finally,the optimum time of stent removal was determined. Results The overall incidence of complications caused by stent placement in group B(23.91%)was significantly lower(P<0.05)than that in group A(47.62%)and group C(56.52%). The most frequent among these complications were bladder irritation(8.70%)and fever(8.70%). The incidence of hydronephrosis exacerbation after stent removal in group A (28.57%)was significantly higher(P<0.05)than that in group B(6.52%)and group C(4.35%). All the other complications were alleviated or disappeared after the removal in all the three groups. There were no significant difference(P>0.05)among the three groups concerning glomerular filtration rate,serum urea nitrogen,and serum creatinine. Conclusion The incidence of complications caused by preoperative double J stent place?ment increased along with the duration of placement,but the exacerbation of hydronephrosis should be concerned if the stent is removed too early. Therefore,the optimal time of stent removal is 4 to 5 weeks after the surgery.
