Male urinary tract
Female urinary tract
The bladder isnt injured often. The bones in the pelvis protect it from most outside forces. But the bladder can be injured by blows or piercing objects. Most often these are related to pelvic fracture. Timely evaluation and proper management are critical for the best outcomes.
What Happens under Normal Conditions?
The bladder is a balloon-shaped organ that stores urine. Its held in place by pelvic muscles in the lower part of your belly. When it isnt full, the bladder is relaxed. Muscles in the bladder wall allow it to expand as it fills with urine. Nerve signals in your brain let you know that your bladder is getting full. Then you feel the need to go to the bathroom. The brain tells the bladder muscles to squeeze (or "contract"). This forces the urine out of your body through your urethra.
