Pain in the kidney area in women with urinary stones or urinary tract infections, both of which have accompanying symptoms, is very intense and sudden, radiating to the lower abdomen or inner thighs, with pain lasting from a few minutes to several hours. If the pain is caused by urinary tract infection, it is often accompanied by abnormal urination and frequent, urgent and painful urination, and in some cases, high fever, nausea and vomiting. For urinary stones, kidney ultrasound can confirm the diagnosis, while urinary tract infections can be diagnosed by doing routine urine and blood tests. Acute pyelonephritis will present with back pain and is usually accompanied by an elevated body temperature. While the diseases mentioned above are diseases of the kidney itself, there are some pains in the kidney area that are not produced by kidney diseases, such as lumbar strain and lumbar spine diseases.
