Stones in the kidney or ureters may occur at any age, but are more common in the third and fourth decades. These renal calculi may be single or multiple, firmly lodged or free. Kidney stones often cause pain, produce blood in the urine, and symptoms of vague abdominal distress. Occasionally, even when large, stones may occur without symptoms, while causing serious and insidious kidney damage.Characteristically, as mentioned above, renal calculi cause severe, sharp flank pain, which is often acute in onset and present intermittently. A small stone being passed in the ureter creates painful colic and the patient usually moves about restlessly, vainly seeking relief. Blood is frequently present in the urine, but at times requires the microscope for its detection. Physical findings may be entirely normal, although tenderness, muscle spasm, or even a lump may be felt in the location.
It is important to search for the original cause of the stone, then attempt to correct it. Most stones after bladder passage can be analyzed to determine their composition. Some are composed of calcium salts; others of oxalate crystals, and less commonly uric acid or cystine may precipitate to form stones. Each of these causes needs to be ascertained in order to correct the diet, avoiding future recurrence.
One of the commonest situations that sets the environment for an attack of colic is inadequate fluid intake. Normally our kidneys require at least one and a half to two quarts of fluid a day! That will maintain urine volume at diluted concentrations, to avoid the precipitation of these salts. A high consumption of milk may result in calcium precipitation and the formation of a stone. Ice cream, cheese, and soft drinks such as cola beverages, and foods high in oxalic acid may provide the situation where stones begin to crystallize. Uric acid stones usually result from a high intake of purines, found in meats, particularly sweetbreads, and other flesh foods obtained from animal organs. Uric acid calculi are usually seen in combination with other symptoms of gout, a metabolic disease traditionally associated with indulgence in rich foods and alcohol. A discriminating, well-balanced diet associated with adequate fluid will usually bring relief to patients who form uric acid stones frequently.
Treatment
The treatment of colic in the urinary tract usually begins at home. Drink a high intake of water, at least one glass of liquid hourly, and begin immediately. Urinary acidifying agents are helpful to deter stones of calcium or oxalate composition, while for uric acid stones the urine should be alkalinized. Vitamin C and cranberry juice are both good acidifying agents for the urine, and are also helpful in treating urinary infections. Diuretic herbs, such as Buchu tea may also be helpful, when combined with a high volume of fluids.
Relief of acute urinary pain can be obtained in a hot tub bath, or with intensely hot fomentations applied to the flank and hip region. At times when flank pain is severe, the treatments will not only modify the pain, but through reflex pathways may help to relax the ureter and alleviate the spasm. Most often the smaller stones (calculi) will pass down into the bladder, where they are then excreted. Since obstruction in the urinary tract can progressively damage the kidney, as well as be painfully disabling, any urinary stones that do not resolve promptly should be evaluated be a competent physician.Newer diagnostic techniques using x-ray contrast, and cystoscopic basket stone retrieval, water immersion shock (sound) wave lithotripsy, and other types of surgery may be necessary to save the kidneys from permanent harm.
