ABSTRACT
Objective To investigate the effect of secondary transurethral electrocision for recurrent superficial bladder cancer.Methods One hundred and twenty patients with recurrent superficial bladder cancer were divided into experiment group and control group by random mechanical sampling method with 60 cases of each.Experiment group underwent secondary transurethral electrocision at 4 weeks after initial transurethral electrocision and received mitomycin bladder perfusion chemotherapy,control group patients underwent initial transurethral electrocision and received mitomycin bladder perfusion chemotherapy.The two groups' follow-up cystoscopy at 3-month intervals,the follow-up time was 6-34 (18.6 ± 6.5) months,the recurrence was compared between each other.Results Within the follow-up period,the recurrence rate in experiment group was significantly lower than that in control group [21.7％(13/60) vs.63.3％(38/60),P＜0.01].Of all the recurrent patients,high grade rumor (G2 and G3 grade) was mainly,the recurrence rate of high grade tumor in experiment group was significantly lower than that in control group [26.2％ (11/42) vs.70.0％(35/50),P ＜ 0.01].Conclusions Secondary transurethral electrocision can reduce the recurrence rate of superficial bladder cancer (especially for the high grade tumor),it can exactly make the classification of malignant tumors and find residual tumor.So it is valuable in the clinical treatment.
