Causes of urinary stone formation
Urinary stones are mostly made up of kidneys, then travel in the urine stream to other places of the urinary tract such as the ureter, bladder, and urethra.
Urinary stones are formed from the tendency to crystallize, depositing crystals in urine.
The composition of urine consists of crystals and colloids (essentially mucoprotein, mucin, nucleic acid ...)
Classification of urinary stones
Classification of urolithiasis has many ways. Can be classified by gravel properties or gravel location.
Classification of urological stones by chemical composition
Calcium oxalate stones: usually black, clear radiated spines;
Calcium phosphate stones: pale yellow or milky, fragile;
Calcium carbonate stone: chalky white, soft and brittle.
Urate stones: milky white, opaque, may not appear soft and recurrent;
Systin stones: light yellow color, quilts or recurrence;
Struvic stones: yellowish white, often caused by a Proteus-type urinary tract infection.
In Vietnam, most people with urinary stone disease are inorganic stones with> 80% calcium calcium oxalate stones and often exist in a mixture of many chemical components.
Classify urolithiasis by location
Classification by location has types: kidney stones, ureteral stones, bladder stones, urethral stones. In which the incidence of:

How do urinary stones cause damage to the urinary system?
Pebbles cause a blockage
Urinary stones in the renal pelvis can cause complete or partial obstruction, and the size of the stones causes the renal parenchyma to dilate, the capacity of the pyramids increases, and fibrous parenchyma causes gradual loss of kidney function. gradually.
If stones in the ureter cause obstruction of the ureter also dilates peristalsis and fibrosis gradually.
The stones in the bladder are too large and cannot escape from the urethra, which can cause urinary retention, upstream infections, serious kidney damage or bladder leakage or dangerous atrophy of the bladder.
In the case of kidney stones simultaneously obstructing both sides of the kidneys and ureters can cause acute kidney failure.
Damage due to rubbing
The most common types of stones are hard and thorny stones such as calcium oxalate stones, which, when rubbed, can tear and scratch the lining of the renal pelvis and ureter to facilitate urinary infection.
The friction also causes bleeding in the urinary system, accelerating the process of fibrosis of the renal parenchyma and urethra, narrowing the urinary tract causing more obstruction.
The end result is kidney failure.
Urinary tract infection
Urinary infections can occur due to obstruction or rubbing of stones with the walls of the renal pelvis, ureters, etc. causing edema, mucosal ulcers, and fibrosis gradually leading to kidney failure.
In addition, the process of urinary infection also eliminates many corpses of bacteria, leukocytes, and epithelial cells. The trend of deposition, crystallization in the urinary tract is incessant, in the condition of having more and more foreign objects, it will continue to form new stones.
