Create an illustration for a urology event that does not include people. The image should focus on scientific elements related to urology. Consider incorporating anatomical diagrams of the urinary system, kidneys, bladder, and ureters. Include elements such as medical instruments, like a cystoscope or ultrasound machine, and molecules or DNA strands to represent medical research. The color scheme should be professional and clean, using shades of blue, white, and grey to evoke a clinical and scientific atmosphere. The style should be modern and detailed, suitable for a medical conference or seminar.
