Effects of simultaneous transurethral resection of prostate and solitary bladder tumors smaller than 3 cm on oncologic results.

OBJECTIVES: To investigate the effect on the oncologic outcomes of treatment with transurethral resection of patients with a solitary bladder tumor smaller than 3 cm with a superficial appearance and benign prostatic hyperplasia.

METHODS: The follow-up data from 34 men (group 1) who had undergone transurethral bladder tumor resection alone and 31 men who had undergone both transurethral prostate resection and transurethral bladder tumor resection at the same operation (group 2) in our clinic from 1996 to 2004 were retrospectively examined. The groups were also compared with each other. The recurrence and progression rates, elapsed time to recurrence, and the recurrence rates in the bladder neck and prostatic urethra were determined and compared. Statistical analysis was performed using the Mann-Whitney U and chi-square tests.

RESULTS: The patients were followed up for at least 12 months (mean 28.9, range 12 to 98). The average follow-up period for group 1 was 27.4 months (range 12 to 91) and was 30.5 months (range 12 to 98) for group 2. The recurrence and progression rates for groups 1 and 2 were 41.2% and 8.8% and 35.5% and 9.7%, respectively. Recurrence in the bladder neck and/or prostatic urethra developed in 1 patient in each group. No statistically significant differences were found between groups in terms of follow-up time, recurrence, progression, recurrence in the prostatic urethra and/or bladder neck, and elapsed time to recurrence.

CONCLUSIONS: According to our results, transurethral prostate resection can be safely performed with transurethral bladder tumor resection simultaneously in selected patients with severe lower urinary tract symptoms and a superficial solitary tumor smaller than 3 cm.
