RESUMEN
Objective To investigate the effect of the secondary transurethral resection in the treatment of non-muscle invasive bladder cancer(NMIBC).Methods 186 cases with NMIBC were randomly divided into control and experimental groups,both groups were treated by transurethral resection of bladder tumor(TURBT),and experimental group received the secondary TURBT after 4 weeks of the first TURBT.The recurrences of two groups were compared.Results The recurrence rate was significantly lower in experimental group than in the control group(13.8％ vs.37.0％,x2 =13.17,P＜0.05).The recurrence number of the original site was significantly less in experimental group than in the control group(x2 =8.35,P＜0.05).Conclusions The secondary TURBT plays a positive role in NMIBC recurrence.
