We generally believe that the development of nephritis in the later stage will cause a certain degree of renal failure and loss of renal function, affecting the body's urinary system and metabolism. If toxins and waste cannot be excreted from the body, over time, it is likely to cause complete loss of renal function or the occurrence of uremia. So what are the treatment principles for renal failure?
Polyuria stage: After the oliguria stage, renal blood flow and glomerular filtration rate increase, leading to polyuria and entering the polyuria stage. However, this does not mean that it has already recovered, as azotemia still exists and renal tubular concentration function has not been restored. There are still disturbances in water and electrolytes. The manifestation is that the 24-hour urine volume increases to over 1500 milliliters, with most reaching 6000 milliliters. Of course, the daily urine volume gradually increases. As long as the daily urine volume reaches over 400 milliliters, it indicates the beginning of the polyuria phase. The duration of polyuria is approximately 7-14 days. The polyuria phase indicates that renal function begins to recover, and as urine volume increases, various disorders during the oliguria phase gradually improve. But it is also prone to a negative balance of water and electrolyte, such as dehydration, low blood potassium, low blood sodium, or high blood calcium. At the same time, due to long-term consumption, the patient's resistance decreases and is prone to infection.
Recovery period: After the polyuria period, the recovery period enters. Depending on the patient, the duration of the recovery period varies, usually from 3 to 12 months. During this period, there is often renal tubular dysfunction, with most cases completely returning to normal, while only a few cases may develop into chronic renal insufficiency due to residual renal dysfunction.
The treatment principle for renal failure is: as acute functional failure is mostly reversible, any treatment method should be careful not to aggravate the damage. Focus on the oliguria period, try to reduce various disorders in the oliguria period, instead of focusing on kidney disease, focus on "retaining people", that is, rescue patients to prevent death. Specifically, remove the primary factors, correct water electrolyte and acid-base balance disorders, actively treat serious complications such as heart failure, heart rhythm disorder, encephalopathy, irritability ulcer bleeding, and dialysis therapy should be taken as far as possible if conditions permit. The treatment of polyuria mainly involves preventing negative balance of electrolytes and water, supplementing what is lacking, and also preventing infection. During the oliguria period, it is important to ensure that the patient has sufficient calorie supplementation. Due to the long recovery period, it is important to try to protect renal function from damage and not neglect it. The treatment of acute renal failure with traditional Chinese medicine is mainly in the period of polyuria and recovery, which can promote its recovery and enhance the patient's physique. The main manifestation is the deficiency of both qi and yin. The method of supplementing qi and nourishing yin is adopted, and Shengmai Yin combined with Zengye Tang is used for treatment. Drugs such as American ginseng, Ophiopogon japonicus, Radix Scrophulariae, Radix Rehmanniae, and Salvia miltiorrhizae are used. If the body is yang deficient, drugs such as dodder seed, Xianmao, Xianling spleen, etc. can be added. For the treatment of oliguria, there are also reports that it can be treated according to the traditional Chinese medicine syndrome of "urinary obstruction" based on dialectics, but the therapeutic effect is not very certain. At the same time, toxic drugs such as Gansui, Euphorbia, and Phytolacca should not be blindly used.
The two important periods of renal failure need to be grasped accurately, which is the key to treating renal failure. Generally, traditional Chinese medicine uses these two periods to promote faster kidney recovery and achieve twice the result with half the effort. However, we need to choose appropriate drugs to avoid aggravating kidney loss.
