Should a Second Transurethral Resection Be Performed in All Patients with T1 or High-Grade Non-Muscle-Invasive Bladder Cancer?

The second TUR confirmed the presence of residual cancer and tumour understaging in a significant number of T1 and high-grade tumours. This is a strong argument that supports the recommendation of second TUR in patients with T1 or high-grade NMIBC.
