The harm of ureteral calculi is serious. If it is not discharged in time, it will seriously affect your health. Drinking tea in time is helpful to regulate and improve the discharge of stones. What kind of harm does ureteral calculi have?
1, local injury: small stones are easy to scratch the urinary tract mucosa and cause bleeding and renal colic. Large, relatively fixed or staghorn urinary calculi can cause epithelial exfoliation and tissue ulcer.
2, urinary tract obstruction: after urinary tract obstruction, the ureter and renal pelvis above the obstruction will expand hydronephrosis. If both urinary tracts are obstructed, it will lead to uremia.
3, urinary tract infection: urinary tract infection complicated with bacterial infection, severe urinary tract infection may also cause leukemia, threatening people's lives.
4, renal function damage: stones cause obstruction, especially long-term obstruction of ureteral stones will cause hydronephrosis, renal function damage, even if the stone is removed or crushed after complete loss of renal function, renal function can not be restored.
5, causing tumors: long-term stimulation of the urinary tract by stones will cause qualitative changes in the urinary epithelium, which will cause tumors, and hematuria will occur when suffering from tumors.
In addition, asymptomatic ureteral calculi can cause the following hazards:
1, causing typical renal colic and microscopic hematuria: stones in the middle and upper ureter are blocked or move down, which often causes typical renal colic and microscopic hematuria, often accompanied by nausea and vomiting; If stones get stuck in the upper ureter, the pain will be in the waist and upper abdomen, and even spread to the testis or vulva. In the middle section, the pain is usually in the waist and lower abdomen.
2. Complicated infection: Ureteral calculi can easily lead to urinary tract obstruction, which can cause hydronephrosis of different degrees, complicated infection, damage to renal parenchyma, pyelonephritis and renal abscess. The higher the stone site, the more serious the obstruction, the longer the time, the more serious the complicated infection and the more serious the renal damage.
3, leading to bleeding: stones will stimulate and scratch the ureteral mucosa, leading to bleeding, leading to ureteral dilatation, tube wall thinning, elongation and bending more serious. The ureter with incarcerated stones is fibrotic due to tissue proliferation caused by inflammation, and the ureter becomes thicker, but it is rare for stones to break through the ureter.
