Kidney stones are a very dangerous urinary disease that may persist for a long time without obvious symptoms, especially in larger stones. When the stones are small, they may enter the ureteral junction or ureter with urine, causing obstruction of the ureter, and then symptoms such as pain and hematuria may occur. However, most kidney stones are asymptomatic or have mild symptoms, even if they have caused kidney function damage. If kidney stones are not taken seriously in the early stage, the best time for treatment will be lost, and eventually there will be pain in the lower back and abdomen, hematuria, obstruction, urinary tract infection, kidney atrophy, kidney failure and uremia. Here, let’s take a look at what complications will be caused by kidney stones? 1. Difficulty in urination If the stone falls into the urethra, the urethra will be obstructed to form difficulty in urination. 2, high fever When kidney and ureteral stones are infected together, it will cause patients to have general symptoms such as fever, chills and shivering, and they will feel chilly no matter how many clothes they wear. At the same time, pus may appear in the urine. If the stones cause hydronephrosis for a long time, the pressure above the obstruction will be too high and the blood flow to the kidney will be reduced, which will lead to kidney atrophy, kidney function loss, tubular necrosis and kidney function loss. 4, the formation of uremia Kidney stones can easily cause urinary tract obstruction, resulting in a large amount of water in the kidney pelvis, swelling, loss of original function, such as bilateral urinary tract obstruction at the same time, will become uremic syndrome. 5.Cancerous transformation Kidney stones can cause chronic inflammation and eventually induce cancer if they stimulate the kidney for a long time. Kidney stone is the most common urinary disease, which is prone to complications and is very harmful to the body. If found, please go to regular medical institutions for consultation in time. If the best time for treatment is lost, it will not only cause complications and harm your health, but also increase the treatment cost.
