Renal colic

If sore left kidney, the reasons can be different. One of the strongest pain syndromes is manifested in renal colic. It manifests itself in the pain attack in acute obstruction of the ureter. This condition can be caused by a tumor or adhesions. The passage at the narrowed ureter foreign entities (clots or stones), cause obstruction, resulting in the development of renal colic. The reason for its development is also increase pressure in the kidneys back of urine reflux. The kidney starts to swell and increase in size, which prevents a dense fibrous capsule, in which it is located. The result is compressed by the internal kidney structure, leading also to increased pain.

Renal colic is considered one of the diagnostic criteria for urolithiasis. Her symptoms manifested in unilateral pain in left kidney or right kidney, violation of urination, rise in body temperature. The pain may radiate to the lower back, in the left hypochondrium, in the solar plexus and in the course of the ureter to the groin. When kidney hurts on the left side, reduced intestinal peristalsis, abdominal wall is tense.

Attention! If the stone completely covers the ureter and there is no outflow, the body very quickly there are signs of intoxication. They are manifested in the increasing General weakness, nausea, vomiting, disorders of the gastrointestinal tract.

Thrombosis of the renal artery

Suddenly developing the condition when it left the kidney requires immediate hospitalization. This condition can be caused by renal artery thrombosis. Trapped in the clot shuts off the lumen and thus there is strong pain, high blood pressure, fever, nausea, vomiting, dyspepsia and anuria. The pain is shingles character and achieves such power that the patient can lose consciousness.

This will help to properly collected history, as well as additional research:

  • Ultrasound of the kidneys and urinary tract;
  • Urinalysis;
  • Biochemical analysis of blood;
  • Radiography of the abdomen.

Ultrasound of the kidneys and urinary tract – one of the most effective hardware diagnostic methods of research of urology

Treatment of renal colic is aimed at relief of pain. If symptoms pain syndrome suggests this pathology, the assistance can be provided even before the arrival of the ambulance in the form of a hot bath, which will reduce spasms and severe pain. But, this procedure is contraindicated in other conditions associated with pain in the left kidney. What to do when the pain in her left kidney if it is associated with urolithiasis? Before the arrival of the specialist, the patient can be given antispasmodics and analgesics (spazmalgon, baralgin, etc.).

Medical aid at a renal colic needs to be in a specialized hospital by doctors-urologists.

Chronic pain renal syndrome

Chronically occurring disease of the kidneys accompanied by an increase in body and cause moderate pain. Why hurt the left kidney in diseases such as chronic pyelonephritis, nephroptosis, or glomerulonephritis? Causes of pain associated with the peculiarities of these diseases.

In inflammatory diseases of the kidney

The pain of whining character occurs in chronic pyelonephritis, pyelitis, tuberculosis, hydronephrosis, polycystic renal and other pathologies. It occurs in the morning and can be combined with signs of disruption of the digestive tract – nausea, vomiting, dyspeptic disorders. Glomerulonephritis is an inflammatory process develops very quickly and join pain, swelling of the face in the morning, reducing the amount of urine passed, in which there is blood.

In hydronephrosis the pain of blunt, expander character are concentrated in the lumbar region. Pyelonephritis is tenderness in the region of the kidney is characterized by a constant presence. Kidney hurts on the left or right or both sides. In addition to pain, pyelonephritis characterize facial swelling in the morning, increased body temperature and signs of intoxication.

The treatment of pyelonephritis is aimed at relieving the inflammatory process. Improving the patient’s condition and the pain occurs within 7-10 days course of antibiotic therapy. But in order to prevent complications, the course continues until the complete recovery.

Nagging pain typical of nephroptosis (omission kidneys). It occurs after severe prolonged exercise in the upright body position (lifting and carrying goods). If you take a horizontal posture, then the soreness goes away.

Nephroptosis can cause pain in the left kidney area

The initial stage of nephroptosis is treated with conservative methods:

  • Physical therapy to strengthen the muscles of the abdominal wall. With the same purpose appointed a special bandage that helps hold the kidney in its physiological place.
  • The weight assigned to the diet, helping to build fatty tissue around the kidney. She keeps them in the physiological situation.
  • Appointment vitamin, with the aim of promoting good health.
  • When conservative methods do not give effective results and a kidney cannot be undone, is performed surgery. Its goal is to return the body to physiological place and fixing it there surgically.

After surgery, the pain associated with prolapse of the kidney pass.


Constant nagging pain in the region of the left kidney occurs in hydronephrosis, when an organ increases in size due to excess amount of urine. The discomfort continues when you change body position. Join in symptoms of toxicosis – nausea, vomiting.

Treatment of hydronephrosis is surgical method. Preparation for surgery aimed at relieving pain, lowering blood pressure and inflammation in the kidney. The operation is to restore the patency of the urinary system and plastic structural tissue of the pelvis.

When tumors

Pain when tumors in the kidneys are not permanent in nature and cause discomfort in the lumbar region, or to the left or right. Malignant tumor of the left kidney may be as an independent disease of the body and cause metastases from other cancerous organs. First, pain is not, but with the growth of the tumor can be unpleasant tenderness to palpation of the kidney.

  • Puncture of the cyst through the skin. Substance cyst is removed through the drainage;
  • Laparoscopy is considered to be the most popular, safe and effective method. The cyst is excised through the holes in the abdominal wall with the help of special tools.
  • Abdominal surgery is indicated for suspected degeneration of the cyst to a malignant tumor, or if a suppuration or an independent autopsy.

For cancer of the left kidney is abdominal surgery to remove the tumor, they damaged organ metastases. After surgery is chemotherapy, radiation, hormonal, immune and gene therapies.

Atherosclerosis the kidneys

Aching pain that occurs on a background of atherosclerosis of renal vessels. They occur periodically, are not of intense nature.

The symptoms are very similar to essential hypertension, as accompanied by, in addition to pain in left side high blood pressure. To differentiate atherosclerosis of renal blood vessels from hypertension by using laboratory tests of urine. They observed a large amount of protein, erythrocytes and leucocytes.
The danger of arteriosclerosis of the kidneys is blockage of the major lumen of the renal vessels and in the development of complications of infarction of the kidney, necrosis of the renal structural units, or rupture of the renal artery.

Conservative methods of treatment of atherosclerosis of the left kidney is directed to the suspension and stabilization process. Assigned antiplatelet agents, angioprotectors, antispasmodics, statins, immunomodulators, vitamins. The great value has change of dietary habits and overall lifestyle aimed at preserving the capacity of the kidneys.

Surgery is indicated in critical States associated with the failure of kidney functions. But even surgical method does not eliminate the true cause of atherosclerosis. Therefore, the main treatment of this disease remains conservative therapy.

Atherosclerosis of the renal arteries is a dangerous condition that is accompanied by a large number of pathological symptoms, including pain

Surgical methods:

  • Prosthetics – replacement of the section of the renal artery;
  • Bypass surgery – perform a workaround around shtrobirovaniya portion of the vessel;
  • Stenting – inserting in the affected area of the stent (frame), which expands the narrowed lumen of the artery.
Post-traumatic pain

They arise after injuries or ruptures of the kidneys. Their intensity depends on the severity of the injury and may be accompanied by a sharp decrease in blood pressure and shock due to internal bleeding.
