Many diseases can be combined with urinary stones, these diseases are: 1, primary hyperparathyroidism parathyroid adenoma, parathyroid hyperplasia and other diseases can make the secretion of parathyroid hormone increased, resulting in bone decalcification; can also increase the intestinal absorption of calcium, which in turn makes the blood calcium, urinary calcium elevated. This is an important reason for the formation of calcium-containing stones. 2.Traumatic paraplegia Due to paraplegia or trauma and other reasons such as long-term bedridden can cause bone decalcification, and the occurrence of hypercalciuria. On the other hand, because of neurogenic bladder dysfunction is also easy to form stones, especially when combined with urinary tract infection. 3, urinary tract obstruction disease obstruction of any part of the urinary tract can lead to the formation of stones. The more common ones are prostatic hyperplasia, urethral stenosis, ureteral stenosis, retroperitoneal tumor compression of ureter, renal pelvis ureteral junction obstruction and so on. The reoccurrence of stenosis after urinary tract surgery can also be the cause of stone occurrence or recurrence. 4, gout about 10% of the patients with gout will synthesize and uric acid stones due to the increase of uric acid water in blood and urine.
