What causes pain in the kidney area? Is it related to kidney disease?

At present, more and more patients are diagnosed with kidney pain, which is also commonly known as low back pain. The most obvious pain is unilateral or bilateral pain. This not only affects the patient's daily exercise life, but also makes the patient very sensitive to pain when bending over or squatting. There are many main causes of kidney pain, usually caused by infection, such as kidney stones, cysts, ureteral stones and other diseases. These causes are very widespread and harmful, and require timely examination and treatment.

What is kidney pain?

The kidneys are located on the left and right sides of the spine near the waist. Kidney pain refers to an uncomfortable symptom of pain in the kidney area of ​​the waist. Kidney pain can be caused by various reasons, such as infection, cysts, stones, fatigue, etc. After discovering kidney pain, you should look for the cause to prevent the original condition from getting worse due to inattention.

What are the causes of kidney pain?

The most common pathogen causing kidney pain is Staphylococcus aureus. The bacteria can enter the kidneys through the blood from purulent lesions in other parts of the body, such as boils, sores, abscesses, infected wounds, upper respiratory tract infections, and infections of tissues adjacent to the kidneys. In the early stage, the lesions are limited to the renal cortex to form multiple tiny abscesses, which may then aggregate into multi-chamber abscesses. In some patients, small abscesses may merge into large abscesses and become renal pain. In a few patients, in the late stage, the renal pain near the cortex may break through the capsule and develop into perinephric abscesses. The abscesses near the renal calyx may perforate and drain into the renal pelvis, and bacteria may be found in the urine.

Other reasons such as cysts and stones can also cause kidney pain. Usually ureteral stones can cause severe pain. Renal cysts and various types of nephritis can also cause kidney pain due to damage to the renal interstitium. After sitting for a long time or walking for a long time, you may feel soreness and swelling in the kidneys.

How is kidney pain diagnosed?

Kidney pain may have no symptoms in the early stages, and the primary infection may have healed and been ignored. In the later stages, renal pain occurs suddenly and is accompanied by chills, high fever, loss of appetite and other manifestations of bacteremia or toxemia. Renal pain, tenderness, and percussion tenderness may occur on the affected side. Sometimes, low back pain affects leg movements, and the swollen kidney can be felt, and the waist muscles are tense.

Regarding the diagnosis of kidney pain, there is a history of infectious foci, such as upper respiratory tract infection, furuncle, abscess, wound, etc. High fever, chills, symptoms of bacteremia, low back pain, lumbar tenderness, percussion pain, and swollen kidneys can be felt. The diagnosis can be made with the help of blood urine test, B-type ultrasound and CT scan.

At the same time, relevant auxiliary examinations can also help patients make a diagnosis, such as an increase in white blood cells, an increase in segmented nuclear cells, and positive blood bacterial culture; pus cells in the urine, bacterial growth in urine culture, and bacteria can be found in urine sediment smear staining;

Abdominal X-rays showed that the affected kidney was enlarged and the renal shadow was blurred; intravenous urography showed that the renal calyces in the lesion area were compressed and deformed; B-ultrasound showed an irregular outline of the abscess, which was a low-echo area; CT renal scan showed a circular bloodless area, and the CT value was between a cyst and a tumor.

Treatment of Kidney Pain:

1. Kidney pain caused by infection:

For kidney pain caused by infection, sufficient antibiotics can usually be used after diagnosis: for example, penicillin, carbenicillin, and vancomycin. Early treatment is often possible. Early drainage after diagnosis can alleviate systemic symptoms and reduce patient consumption. If kidney pain is not drained well and kidney damage is severe, nephrectomy may be performed if necessary. If there is a perirenal abscess, perirenal incision and drainage should be performed, and kidney pain should be treated with expanded incision drainage.

2. Kidney pain caused by fatigue:

Many patients' kidney pain manifests as pain in the lower back. The most common causes of lower back pain are renal colic, lumbar muscle strain, and lumbar bone hyperplasia. Gastritis can also involve lower back pain. At this time, patients should pay attention to rest, reduce strenuous exercise, and undergo restorative treatment and recuperation.
