Clinical effect of simultaneous transurethral resection of bladder tumor and benign prostatic hyperplasia on recurrences of bladder tumor

Objective:To evaluate the effect of simultaneous transurethral resection of bladder tumor(TURBT)and benign prostatic hyperplasia(TURP)on recurrences at the bladder neck and prostatic urethra.Methods:Data of 47 patients underwent simultaneous TURBT and TURP were reviewed(26 with single tumor and 21 with multiple tumor).The follow up time,recurrence time,the local,the number of tumor and the tumor progression were recorded retrospectively.The relationship of the recurrences of bladder tumor and simultaneous transurethral resection of bladder tumor(TURBT)and benign prostatic hyperplasia(TURP)were analyzed systematically.Results:During the 1 to 4 years of followup(mean 2.9)the average tumor recurrence rate was 68.1%,53.8% in single tumor group and 85.7% in mutiple tumor group(P0.05).Recurrences appeared within an average of 15.1 months,17.5 months in single tumor group and 12.4 months in multiple tumor group.Tumor recurrence was at the bladder neck and/or prostatic urethra in 10 of the 47 cases(21.3%).Average time to recurrence at the prostatic fossa was 21.3 months,26 in single tumor group and 20.6 months in multiple tumor group.Tumor progressed to invasiveness was diagnosed in 3 of the 47 patients(6.3%).Conclusions:The present study indicates that simultaneous TURBT and TURP do not negatively affect tumor recurrence at the bladder neck and prostatic urethra,and it may be an effective strategy to deal with the hypertrophy of prostate accompanied with bladder tumor.
