Large intrarenal pelvic stones and calyceal stones are usually caused by urinary tract infection, metabolic diseases, etc. Some patients who are bedridden for a long time are also prone to intrarenal stones.
1. Urinary tract infection: shed epithelial cells, bacterial clumps, parasitic eggs or worms, fecal matter or foreign bodies lead to urinary tract infection, and foreign bodies gradually invade into the renal calyx from the urethra to induce the formation of crystals, which will further cause symptoms.
2. Metabolic diseases: diabetes mellitus, hyperparathyroidism and other diseases will affect the pH value of urine, so that urinary calcium excretion increases, uric acid excretion decreases, and kidney stones are formed.
3. Prolonged bed rest: drinking normal water but habitually holding urine, resulting in increased concentration of calcium, oxalic acid, uric acid and other soluble substances in the urine, precipitation in the renal calyx, inducing the formation of crystals.
In addition, there are many other reasons that can lead to renal pelvis, renal calyx stones, it is recommended that patients go to the hospital in time for examination, under the guidance of the doctor for targeted treatment.
