Information for Patients
A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. It may be as small as a grain of sand or as large as a pearl. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away. It may get stuck in the urinary tract, block the flow of urine and cause great pain.
The following may be signs of kidney stones that need a doctor's help:
- Extreme pain in your back or side that will not go away
- Blood in your urine
- Fever and chills
- Urine that smells bad or looks cloudy
- A burning feeling when you urinate
Your doctor will diagnose a kidney stone with urine, blood, and imaging tests.
If you have a stone that won't pass on its own, you may need treatment. It can be done with shock waves; with a scope inserted through the tube that carries urine out of the body, called the urethra; or with surgery.

Pelvic pain occurs mostly in the lower abdomen area. The pain might be steady, or it might come and go. It can be a sharp and stabbing pain in a specific spot, or a dull pain that is spread out. If the pain is severe, it might get in the way of your daily activities.
If you're a woman, you might feel pain during your period. It could also happen when you have sex. Pelvic pain can be a sign that there is a problem with one of the organs in your pelvic area, such as the uterus, ovaries, fallopian tubes, cervix, or vagina. If you're a man, the cause could be problem with the prostate. In men and women, it could be a symptom of infection, or a problem with the urinary tract, lower intestines, rectum, muscle, or bone. Some women have more than one cause of pelvic pain at the same time.
You might have to have lab, imaging, or other medical tests to find the cause of the pain. The treatment will depend on the cause, how bad the pain is, and how often it occurs.
