An enlarged kidney is a condition in which a kidney is larger than its normal size (length: 10-12cm, width: 5-6cm, thickness: 3-4cm). Generally, enlarged kidneys indicate some kidney diseases.
Some common illnesses that may cause this to occur include Polycystic Kidney Disease (PKD), Kidney Stone, Hydronephrosis, and Pyelonephritis. Most of the time, the enlarged kidney is treated by treating the underlying cause of this condition. This article is to explain you why those renal diseases cause enlarged kidneys
1. Polycystic kidney disease
Polycystic kidney disease is a disorder characterized by clusters of fluid-filled cysts within the kidney. The fluid-filled cysts grow and cause the kidneys to expand, leading to an enlarged kidney. It is a common symptom of polycystic kidney disease. Other symptoms may include abdominal swelling, back pain, headache, urinary tract infection and high blood pressure. If left untreated, more serious health problems such as stroke, heart attack and kidney failure may occur.
2. Kidney stone
Kidney stone is usually a deposit of uric acid crystal or calcium. The development of stones inside the kidneys can cause them to grow, leading to an enlarged kidney. Kidney stones can grow quite large. An individual with this condition may experience frequent and painful urination, nausea, fever and pain in the back, abdomen or sides.
It refers to one enlarged kidney that is due to a blockage in the outflow of urine. Hydronephrosis can be caused by a kidney stone, blood clot, urinary tract infection, or a tumor. The main symptom of hydronephrosis is flank pain. Chronic hydronephrosis may have no symptoms.
Pyelonephritis is an infection of the kidneys resulting from a bladder infection that spreads to the kidneys or from an infection of the blood. Signs and symptoms may include enlarged kidneys, tenderness on one or both sides of the lower back, chills, fever, painful and frequent urination, foul-smelling urine, cloudy urine and spasms that can cause intense pain. Antibiotics are used to treat the infection.
For diabetic nephropathy, kidneys get bigger early then start slowly shrinking over the years. Usually the patient has a protein increase in urine.
