The document describes the anatomy of the ureter, bladder, and urethra. It discusses the length, parts, relations, blood supply, and lymph nodes of the ureter. It outlines the ligaments, relations, sphincter, blood supply, nerves, and lymph nodes of the bladder. It details the sphincters, parts, blood supply, and lymph nodes of the male and female urethra.
