Urology is a specialized field of medicine concerned with the health and functional disorders of the urinary system, primarily affecting the kidneys, ureters, bladder, and urethra. The urinary system is vital for maintaining homeostasis by filtering waste products, regulating electrolyte balance, and managing fluid volume. Kidney function is central to this process, filtering blood to create urine, while the bladder serves as a temporary reservoir. The system's ability to regulate fluid pH and excrete metabolic waste products is essential for sustaining life, and urological practices address conditions ranging from kidney stones and urinary tract infections to structural abnormalities within these excretory passages.
