Renal function is usually not restored after 3 years of severe hydronephrosis.
Hydronephrosis refers to the obstruction of urine drainage, which leads to dilatation of the renal pelvis and calyces after a large amount of long-term accumulation, and then causes atrophy of the renal parenchyma and loss of function. Symptoms of hydronephrosis include obstruction, renal colic, difficulty in urination, elevated blood creatinine, etc. If complicated by infection, the symptoms of acute pyelonephritis can also appear.
The treatment of hydronephrosis requires comprehensive consideration, and the treatment plan is formulated according to the cause of the disease, the extent of the disease, and the degree of renal function impairment. In early stage of severe hydronephrosis, renal function can be recovered after active treatment.
If severe hydronephrosis exists for a long time, it may lead to significant destruction of renal parenchyma, severe impairment of renal function on the affected side, and the renal function on the opposite side can no longer be fully compensated for, and blood creatinine can be elevated, and even if active treatment is given at this time to solve the obstruction, the renal function can not be restored in general.
Patients with hydronephrosis are advised to consult regular hospitals in time and standardize the treatment under the guidance of physicians.
