Minor hydronephrosis is usually not serious in those with mild condition.
Common causes of hydronephrosis include kidney stones, ureteral stones, kidney tumor, ureteral cancer, prostate hyperplasia and so on. Minor hydronephrosis is mild, usually asymptomatic or symptomatic, and renal function is not affected, but it should be examined to clarify the cause of the disease and prevented and treated actively.
When mild hydronephrosis develops into moderate to severe hydronephrosis, it may pull the kidney peritoneum, causing symptoms such as back pain and backache, and when combined with infection, it may also cause fever, increased white blood cells, nausea, vomiting and other symptoms. Hydronephrosis will also compress the surrounding normal kidney tissues, affecting the kidney function, leading to renal insufficiency, causing oliguria, anuria, elevated blood creatinine and other symptoms of kidney damage, which is more serious at this time.
Patients with mild hydronephrosis should go to the hospital in time, improve the examination, clarify the cause of the disease, and be treated under the guidance of a professional physician to avoid delaying the condition.
