What are the symptoms of hydronephrosis?

There may or may not be direct symptoms of hydronephrosis depending upon the underlying cause.

Individuals with acute hydronephrosis, for example symptoms from renal colic due to a kidney stone begin with an acute onset of intense flank or back pain radiating to the groin, associated with nausea, vomiting, and sweating. Colicky pain comes and goes and its intensity may cause the person to writhe or roll around or pace in pain. There may be blood seen in the urine.

Chronic hydronephrosis develops over time and there may be no specific symptoms. Tumors in the pelvis or bladder obstruction may develop silently and the person may have symptoms of kidney failure. These are often non specific and may include weakness, malaise, chest pain, shortness of breath, leg swelling, nausea and vomiting. If electrolyte abnormalities occur because the kidneys are unable to regulate sodium, potassium, and calcium, there may be heart rhythm disturbances and muscle spasms.
