Assessment of the clinical efficacy of simultaneous transurethral resection of both bladder cancer and the prostate: a systematic review and meta-analysis

OBJECTIVE

In this study, we aimed to examine the clinical efficacy of simultaneous transurethral resection of bladder cancer and the prostate (TURBT + TURP) in non-muscle invasive bladder cancer (NMIBC) and benign prostatic hyperplasia (BPH) patients.

METHOD

We conducted systematic research in PubMed, EMBASE, and Cochrane Library databases to identify retrospective studies and prospective randomized controlled trials (RCTs) comparing patient outcomes between TURBT + TURP and TURBT-only patients. The meta-analysis was conducted using Review Manager 5.3.

RESULTS

We identified eight relevant studies involving a total of 1032 patients. We found that patients that underwent TURBT + TURP exhibited significantly lower recurrence rates [odds ratio (OR), 0.70; 95% confidence interval (CI), 0.53-0.93; p = .01] and increased maximal urinary flow rate (Qmax) (WMD, 5.92; 95% CI, 4.67-7.16; p < .001) compared with patients that underwent TURBT-only. However, rates of recurrence at the prostatic urethra/bladder neck and bladder tumor progression, as well as the time to recurrence did not differ significantly between these two groups.

CONCLUSIONS

Simultaneous TURBT + TURP can be safely performed in patients with NMIBC and BPH and improves patient quality of life, without any risk of increasing tumor recurrence or metastasis rates. Comprehensive RCTs are needed to confirm the results of this study.

The recurrence and progression risk after simultaneous endoscopic surgery of urothelial bladder tumour and benign prostatic hyperplasia: a systematic review and meta-analysis

Objectives

To evaluate recurrence and progression risk after simultaneous endoscopic surgery of bladder cancer and benign prostatic hyperplasia (BPH), as simultaneous surgery is not an unusual scenario and theoretically simultaneous transurethral resection of bladder tumour (TURBT) and transurethral resection of the prostate (TURP) can lead to an increased risk of recurrence in the bladder neck and prostatic urethra (BN/PU).

Methods

We conducted a systematic review and meta‐analysis to assess the risk of recurrence (i.e. whole bladder and/or BN/PU) and tumour progression as outcomes after a simultaneous endoscopic surgery of bladder tumour and BPH, as compared to TURBT alone. We queried PubMed and Web of Science database on 1 January 2020. We used random‐ and/or fixed‐effects meta‐analytic models in the presence or absence of heterogeneity according to the I² statistic, respectively.

Results

Nine retrospective and three clinical trial studies were selected after considering inclusion and exclusion criteria. We conducted the meta‐analysis on retrospective and randomised controlled trials (RCTs) separately. Eight retrospective and three RCT studies were included to assess the BN/PU recurrence risk and the summarised risk ratio (RR) was 1.02 (95% confidence interval [CI] 0.74–1.41) and 0.93 (95% CI 0.47–1.84), respectively. Five retrospective and two RCT studies were included to assess the progression risk and the summarised RR was 0.91 (95% CI 0.56–1.48) and 1.16 (95% CI 0.30–4.51), respectively. Eight retrospective and three RCT studies were included to assess the whole bladder recurrence risk and the summarised RR was 0.87 (95% CI 0.78–0.97) and 0.89 (95% CI 0.65–1.21), respectively.

Conclusion

We did not observe any increased risk of total bladder recurrence, BN/PU recurrence, or progression after a simultaneous endoscopic surgery of bladder tumour and BPH, as compared to TURBT alone.
