Kidney pain

Introduction The kidney is located at the back of the spine near the left and right sides of the waist. Kidney pain refers to an uncomfortable symptom of pain in the lumbar kidney area.

Cause

There are many reasons for kidney pain, such as infections, cysts, stones, and fatigue. After the discovery of kidney pain, the cause should be sought to prevent the original condition from worsening due to inattention.

Common pathogen

The most common pathogen caused by infection is Staphylococcus aureus. Bacteria can enter the kidney through other parts of the suppurative lesion, such as sputum, pain, abscess, infected wound, upper respiratory tract infection, and adjacent renal tissue infection. Wait. The initial lesion is confined to multiple microscopic abscesses in the renal cortex, which can be combined into multiple atrial abscesses. Some patients can be merged into small abscesses into small abscesses, which become kidney pain. A small number of patients to advanced stage, near cortical nephritis can break through the envelope. Developed into a perirenal abscess, the abscess of the proximal renal pelvis can be perforated to drain the renal pelvis, bacteria can be found in the urine.

Other causes such as cysts, stones, etc. 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 impaired renal interstitial. After taking a sitting position for a long time or walking for a long time, you will feel the soreness and swelling of the kidneys.

Kidney CT examination of renal ultrasound

Kidney pain can be asymptomatic in the early stage. The primary infection may have been neglected. Later, there is renal pain, sudden onset, accompanied by chills, high fever, poor appetite and other bacteremia or toxemia. On one side, renal pain, tenderness, tenderness and tenderness may occur, and sometimes the back pain may be affected by low back pain, and the swollen kidney may be touched, and the waist muscles are tight.

Regarding the diagnosis of renal pain, there is a history of infection, such as respiratory infections, sputum, abscesses, wounds, etc. High fever, chills, bacteremia, low back pain, lumbar tenderness, snoring pain, and can touch the enlarged kidney, supplemented by hematuria examination, B-mode ultrasound and CT examination can be diagnosed. At the same time, related auxiliary examinations can also help patients to diagnose, such as leukopenia, increased lobular nucleation, and blood bacterial culture can be positive. There may be pus cells in the urine, bacterial growth in urine culture, and bacteria can be found by smear staining of urine sediment. Abdominal X-ray film showed enlarged kidney and blurred kidney shadow. Intravenous urography showed compression deformation of the renal pelvis in the affected area. B-ultrasound showed an irregular abscess contour, and the abscess was a hypoechoic area. A CT scan of the kidney showed a round, blood-free area with a CT value between the cyst and the tumor.

Differential diagnosis

Identification with tenderness in the kidney area.

Renal tenderness means that the kidney is covered at the angle between the lateral edge of the erector spinae and the 12th rib. Nephritis or kidney stones can cause tenderness in this area.
