Abstract

Introduction: Transurethral resection of bladder tumor (TURBT) remains the gold standard method of diagnosing and treating nonmuscle invasive bladder cancer. Laser resection has been demonstrated as a safe and efficacious alternative; however, its mainstream use remains limited. The aim of this review is to comparatively evaluate clinical outcomes of TURBT and laser resection of bladder tumor (LRBT) for bladder cancer. Methods: A systematic review of the literature was performed for studies comparing TURBT and LRBT for bladder cancer. Outcome measurements were recurrence rates, complication rates, patient demographics, operative duration, and inpatient stay. Meta-analysis was performed using Review Manager 5. Results: Twenty studies on 2621 patients (n = 1364 for TURBT and n = 1257 for LRBT) met inclusion criteria. Demographics, including age and gender ratio and follow-up period, were similar in both groups. Recurrence rates were similar between TURBT and LRBT (29.1% vs 28.2%, p = 0.12). TURBT had a significantly greater obturator kick rate (11.5% vs 0.4%, p < 0.0001) and perforation rate (3.7% vs 0.009%, p = < 0.0001). In the six studies which reported on presence of detrusor muscle in the specimen, it was significantly greater in the LRBT group (96.6% vs 88.1%, p = 0.01). There was no significant difference in operative time between the two groups. TURBT was associated with a significantly longer catheter duration (mean difference [MD] 0.98 days shorter in LBRT group; 95% confidence interval [95% CI] -1.45 to -0.5, p = < 0.00001), and length of stay (MD 1.12 days shorter in LRBT group, 95% CI -1.7 to -0.54, p = 0.0001). Conclusions: LRBT for bladder cancer has the benefit of reduced catheter duration, length of stay, and perforation without impacting negatively on operation duration, recurrence rates, or specimen quality.
