24 Chapter 2 Table 4: Influence and knowledge of the recent literature of the respondents Do you have a changed attitude towards conservative treatment of UTUC by recent literature? Not at all 29.6% Yes, for patients with (functional) solitary kidney 21.3% Yes, for patients with a healthy contralateral kidney 49.3% Are you familiar with the following guidelines? AUA guidelines on UTUC 47.8% EAU guidelines on UTUC 91.0% ICUD consensus on UTUC, 2013, Vancouver, Canada 22.4% New Techniques Of all responders, 61.4% consider current available diagnostic methods insufficient for an optimal patient selection (figure 1). Pearson chi-square test showed equal distribution over the knowledge of the guidelines and type of practice (p-value = 0.124). 0% 20% 40% 60% 80% 100% I do not know No Yes Answer distribtion Figure 1: Graphic displaying the distribution of the question (number 14)“do you consider the current diagnostic techniques sufficient for optimal patient selection?”“No”; 61.4% (n=43), “Yes”; 32.9% (n=23) and “I do not know” by 5.7% (n=4) of the responders. OCT and CLE, both aiming for real-time histopathology, are less known among urologists. Optical techniques that aim to improve tumour detection (NBI 71.4%, PDD 31.9%, SPIES 48.6%, digital RIRS 70.0%), are widely known and most techniques are promising accord- ing to the responders, except for PDD. Around one third of responders (29%) see no addi- tional benefit of PDD in the diagnostic work up of upper urinary tract tumours. From the responders, 30.4% see no additional benefit on the use of urinary biomarkers (figure 2). Pearson chi-square tests showed equal distribution over the knowledge of the different opti- cal diagnostics and urinary biomarkers and type of practice (University al vs. non-university
