Urinary Tract

The urinary system or renal system is the organ system that produces, stores, and eliminates urine. In humans it includes two kidneys, two ureters, the bladder and the urethra. The female and male urinary system are very similar, they differ only in the length of the urethra.

Nongonococcal urethritis

NGU refers to an infection of the urethra (the tube running from the bladder through the penis in men or the labia in women through which urine passes) caused by some agent other than gonorrhea. This infection can be caused by any of several different organisms, although the most frequent cause of NGU is a germ called Chlamydia, and is a sexually transmitted disease (STD).
