Is the kidney effusion serious?

Kidney effusion, clinically also known as hydronephrosis, it is a more serious disease. Because when the hydronephrosis has not been actively treated, it can compress the kidney to cause renal filtration function decline, so that renal function shows damage, serious cases may cause uremia and other serious complications. Further examination is needed to clarify the cause and active treatment. Clinically common causes of hydronephrosis: 1. Urinary stones. When stones obstruct ureter, bladder and urethra, it can show that urine produced in the kidney cannot be smoothly discharged and accumulated in the body. Over time, it can cause kidney compression, resulting in loss of renal function, resulting in renal insufficiency and even uremia. 2, various abnormalities of the urinary system. Ureteropelvic junction stenosis, duplication of kidney, duplication of ureter and other abnormalities will show poor renal drainage and cause effusion, long can cause renal cortex thinning, filtration function decline, irreversible damage to renal function, etc. 3, urinary system tumors. Can cause retrorenal compression, such as compression of the ureter. Compression of the ureter orifice causes unilateral or bilateral kidney hydrops, hydrops may affect renal function, causing irreversible damage. Aggressive treatment is needed when a tumor is detected to prolong survival and improve kidney function.
