The major cause for kidney pain is Angiomyolipoma. It is a condition called benign tumor, which occurs in the kidney. This tumor is made of smooth muscle, fat, and vascular elements. But, angiomyolipoma is not hamartomas because smooth muscle and fat are not the normal constituents of renal parenchyma. It is choristoma; as the name indicates, it is composed of muscular, vascular, and fatty tissues. Fatty elements can be detected only at microscopy 7. This is associated with tuberous sclerosis and also lymphangioleiomyomatosis in women. The symptoms of this are kidney pain and many others that lead to asymptomatic. Some of the other symptoms include nausea, hypertension, and fever. The treatment would be conservative in nature in cases of asymptomatic.
Angiomyolipoma are tumors, which are in different sizes like few millimeters to larger than 20 cm. In a pathologic examination, these tumors are lobulated or round and will be in gray or yellow color on the cut sections because they contain fat content.
Urinary infections can also be a cause for kidney pain. This type of condition may be either in the kidney or bladder of the patient. There are many materials in urine; so it is normal that bacteria can grow in it and when this bacterium reaches the urinary bladder it leads to UTI. Some of the other symptoms other than kidney pain are materials in urine, pus, and blood protein. The other symptoms are severe fatigue, night sweats, and chills. The other underlying conditions related to angiomyolipoma are hamartomatosis, abdominal pain, and haematuria.
A patient with angiomyolipoma would tend to be asymptomatic. On an average, 60 percent of the cases were not detected. But in cases of tuberous sclerosis and with patients with larger tumors equal to four centimeters, they had the symptoms. People who have smaller tumors also tend to be asymptomatic.
Some are associated with tuberous sclerosis and many others are not. About 50 percent of people may be affected by this condition. This can happen in 40 percent of women who have lymphangioleiomyomatosis. Isolated angiomyolipoma will occur sporadically. This is often solitary and it contributes towards 80% of the angiomyolipoma. The minimum age of the patients who are associated with isolated angiomyolipoma is 43 years and this is more common in women than men. The interesting fact is that 80% of the cases would experiencing it in the right kidney.
The most important ultrasonographic feature of this is echogenicity. This may also cause acoustic shadowing. The appearance of this is echogenic due to fat content and also the multiple tissues present in it.
There are various examinations by which this can be detected, including MRI,CT Scan, and angiography. Other medical issues by which this can be diagnosed are oncocytoma, renal lipoma, and renal cell carcinoma.
If the tumor does not show symptoms, then there are many treatment methods. There are two factors, which are considered for medications – the size of the tumor and the symptoms. Some of the options, which doctors may suggest are embolization, continued checks, and removal of kidney (either partial or completely).
The treatment options are very few and have to be decided by the specialist. It is very difficult to tell about the treatment without proper diagnosis and check up of the patient, which is done by a specialist. It is better to consult Oncologist or Urologist and take a second opinion before deciding about the treatments.
