Few patients with renal tuberculosis come to the hospital at an early stage because they do not pay attention to or recognize the signs of the development of renal tuberculosis, and some patients even know about pulmonary tuberculosis without knowing the name of renal tuberculosis. Urologic tuberculosis is secondary to tuberculosis lesions in other parts of the body, the most important of which is renal tuberculosis. Among the urological TB, renal TB is the most common and the first to occur, and later spreads from the kidney to the entire urinary system. Therefore, renal tuberculosis actually represents urologic tuberculosis. Early signs of renal tuberculosis Some data show that 3 million people die of tuberculosis each year worldwide, of which 3-4%, or about 100,000, are due to renal tuberculosis. It is evident that renal tuberculosis is still a common disease. The following are the signs of the onset of renal tuberculosis: 1. The earliest sign from the urinary system is often frequent urination, with the number of urinations increasing from the normal 4-6 times a day to more than 10 times a day, and especially at night. This is a symptom caused by irritation of the bladder after urine containing Mycobacterium tuberculosis flows through the kidneys into the bladder. Another important sign is hematuria, but it is often less severe and can only be seen occasionally with the naked eye, but mostly when red blood cells are found on microscopic examination of the urine. The third sign from the urinary system is pusuria, which is manifested by cloudy urine with a large number of white blood cells seen on microscopic examination of the manifestation. All three of these signs are extremely important, but they can be easily confused with common urinary tract infections and prostate disease. 2. Signals from the whole body: fatigue, weakness, loss of appetite, weight loss, low fever, night sweats, flushed cheeks, palpitations, heartburn, insomnia, etc. These phenomena indicate that the tuberculosis bacillus is “causing trouble” not only in the kidneys but also throughout the body, and that the toxin reaction of the bacterium is causing these symptoms. Many patients are finally diagnosed with renal tuberculosis only after they have been transferred to several hospitals, but often the best time for early drug treatment has been missed and the kidney has developed a cavity, pus accumulation and accumulated ureter, or the bladder has developed tuberculosis and hydronephrosis on the opposite side, which require surgery to remove the diseased kidney. Clinically detected renal tuberculosis are late and cure by drug-based anti-tuberculosis treatment alone is rare, therefore, early diagnosis and treatment of renal tuberculosis should be enhanced.
