Understanding Our Kidneys

Kidneys New York, NY

The kidneys are “bean-shaped” organs that sit on either side of the spine, below the ribs and behind the stomach. The kidneys’ main job is waste excretion, while they also regulate blood volume, blood pressure, blood pH, electrolytes, and metabolites in the body. The role of the kidney is to produce urine and send it to the bladder, where it will be excreted from the body. Urine is 90-95% water and 5-10% solids. As blood travels into the kidney through arteries and capillaries, blood plasma squirts out of the capillary and moves into the urinary system. This is where filtration takes place. As the filtration occurs, blood and water move through the renal system until urine is produced and then sent to the bladder.

The kidneys have a very complex circulatory and filtration system. Though the kidneys are the size of a fist, they pump all of the blood of the entire body several times a day. They are an essential organ of the whole body. When the kidneys do not function properly, the body will become septic because waste will not filter out. If blood stops flowing into a kidney, part or all of it could die. Numerous health conditions and abnormalities result from damaged or diseased kidneys:

  • Uncontrolled diabetes
  • Hypertension (high blood pressure)
  • Urinary tract infections
  • Kidney stones
  • Polycystic kidney disease
  • Kidney failure

A primary concern regarding kidney disease is that it presents no symptoms in its early stages. Kidney disease is often referred to as a “silent killer,” because many people do not know they are suffering until the disease has become severe.

If you suffer from recurrent kidney stones, urinary tract infections, have high blood pressure, are African American, or have a family history of kidney disease, it is imperative that you are proactive in managing your health. Dr. Alan I. Benvenisty has extensive experience in vascular diagnosis and treatment for kidney disease and renal failure. Contact our practice today.

Dr. Benvenisty was excellent and helped us with my husband's extensive leg swelling related to diabetes. We had another specialist who didn't help us last year. We're planning to stay with Dr. Benvenisty now! He's detailed oriented, matter-of-fact and friendly. An excellent doctor I would strongly recommend.


Dr. Benvenisty treated my mother in the ER during this time of the covid outbreak. He was a part of a fantastic team of doctors that were brought in to find out what was ailing my mother. He is first and for most experienced in many areas as my mother was diagnosed with pancreatitis. Although he transferred the surgery to another member of his team, he gave me his mobile and kept me informed of her condition/diagnosis at a time where I was unable to be with her myself because of this pandemic. His heart, compassion, understanding and bedside manner are things that I will not ever forget. He is an excellent doctor and truly a great human being.

Howard L.

Dr. Benvenisty is the most caring physician that I know. He is brilliant, highly ethical and trustworthy. His knowledge extends well beyond his specialty. He makes referrals to the best possible physicians. I know Dr. Benvenisty for 25 years and have complete confidence in him.
