Agnieszka Pozdzik M.D., Ph.D. Specialist in internal medicine, holder of the specific professional title in nephrology. My particular areas of interest are the diagnosis and treatment of patients with chronic kidney disease and kidney stone carriers. Chronic kidney disease, also called chronic kidney failure, involves a progressive loss of kidney function. Your kidneys filter waste and excess fluid from your blood, which is then eliminated through urine. Advanced chronic kidney disease can cause a dangerous buildup of fluids, electrolytes, and wastes in your body. But be careful, in the early stages of chronic kidney disease, you may have few signs or symptoms. You may not realize you have kidney disease until it is advanced. Kidney stones, the synonyms of which are kidney stones, renal lithiasis or nephrolithiasis, are painful. In fact, they are associated with an increased risk of chronic kidney disease, high blood pressure and even poor mineralization of your bones. The incidence of kidney stones is increasing in adult women more than men and children, although the reasons for this increase are unclear.
