The Impact of Restaging Transurethral Resection of Bladder Tumour on Survival Parameters in T1 Non-Muscle Invasive Bladder Cancer - Systematic Review and Meta-analysis

T1 high-grade non-muscle invasive bladder cancer (NMIBC) is characterized by a high recurrence rate and progression to muscle-invasive disease in significant number of patients. To overcome limitations of initial transurethral resection of bladder tumour (TURBT), various strategies are proposed in the literature. One of them is the performance of restaging TURBT (re-TURBT). In recent years it has been shown that re-TURBT can provide valuable additional pathologic information. However, its potential effect on survival improvement is debatable and benefits from this procedure have been suggested to be dependent on several clinicopathological factors (e.g. the presence of detrusor muscle in initial TURBT).
