In the 6 months before survey administration, the majority of urologists (67% of those surveyed) had treated over five NMIBC patients who had failed BCG therapy. The preferred course of treatment for these patients was a radical cystectomy, as advised by 79% of the participants. Other preferred options were intravesical chemotherapy (16%) and repeat BCG therapy (5%). Clinical trials were never chosen. Sixty percent gemcitabine (Gem), 20% mitomycin C, 10% docetaxel (Doce), and 10% sequential Gem/Doce were rated as the most preferred intravesical chemotherapy regimens used. Saudi urologists were most reluctant to utilize intravesical chemotherapy because of uncertainty about the treatment's clinical effectiveness (oncological safety) and the absence of specific guidelines from urology societies regarding the use of these drugs. BCG shortages are still a problem in Saudi Arabia, as 79% of respondents reported shortages.
