There are many patients who present with urolithiasis and will visit the urology department. Uremic lesions are due to a hormone in the hypothalamus area called antidiuretic hormone, which in the normal state of secretion, and renal excretory function to form a mutual control and balancing effect. It is necessary to excrete excess water from the body, but not to cause a large amount of water to be excreted from the body. Therefore, antidiuretic hormone will play that role, that is, the role used to control, coordinate, and supervise whether the amount of renal excretion is appropriate and safe. If there are certain neurosurgical diseases that lead to abnormalities in the functioning of the hypothalamus, the secretion of antidiuretic hormone decreases and the patient develops urolithiasis. In this case, there will be a large amount of urinary output and a decrease in the density and specific gravity of the urine, at which point the patient should go to the neurosurgery department. There is a significant difference between urosepsis and increased urination, which can be identified by a simple diary of urination. If the daily water intake and urine output are basically balanced, the phenomenon of increased urine output is normal, without any problems and does not require treatment. However, if the daily urine output is more than 2000-3000 ml, but the water intake is not up to this figure or there is a significant gap, then we should consider the possibility of uremic avalanches.
