If the condition of moderate hydronephrosis is serious, if it is not treated in time, it may be combined with infection; if the obstruction of the urinary tract is not relieved for a long time, it will lead to the decrease or even loss of renal function on the side of the obstruction, and the occurrence of renal failure and so on.
Urine from the renal pelvis is blocked, the accumulation of intrarenal pressure increases, the renal pelvis and calyces are dilated, the renal parenchyma atrophies, and the function decreases, which is called hydronephrosis. When the volume of hydronephrosis exceeds 1000 ml or the total amount of urine in a child exceeds 24 hours, it is called giant hydronephrosis.
Moderate hydronephrosis is serious, not actively treated, and the complication of infection is manifested as acute pyelonephritis symptoms, with chills, high fever, lumbago and bladder irritation symptoms. If the obstruction is not relieved, the infected hydronephrosis is hard to be cured, or it may develop into abscess kidney, the abdomen may be able to find a mass, and the patient often has fever and emaciation.
If the urinary tract obstruction is not relieved for a long time, it will lead to the decrease or even loss of renal function on the obstructed side. Isolated kidney or bilateral upper urinary tract complete obstruction can appear anuria, renal failure.
Patients with moderate hydronephrosis should go to the hospital in time and receive standardized treatment under the guidance of professional physicians.
