Left untreated, severe hydronephrosis can lead to permanent kidney damage. Rarely, it can cause kidney failure. But hydronephrosis typically affects only one kidney and the other kidney can do the work for both. What is the main cause of hydronephrosis?
Hydronephrosis is usually caused by a blockage in the urinary tract or something disrupting the normal workings of the urinary tract. The urinary tract is made up of the kidneys, the bladder, the ureters (the tubes that run from the kidney to the bladder) and the urethra (the tube that carries urine out of the body).
Is hydronephrosis an emergency?
Hydronephrosis is a true emergency in patients with only one kidney and should the person believe that the lone kidney is at risk, urgent medical care should be accessed. What is the best treatment for hydronephrosis?
Most people with hydronephrosis will have a procedure called catheterisation to drain the urine from their kidneys. Depending on the underlying cause, medication or surgery may be needed afterwards to correct the problem.
Can hydronephrosis be cured?
Hydronephrosis is usually treated by addressing the underlying disease or cause, such as a kidney stone or infection. Some cases can be resolved without surgery. Infections can be treated with antibiotics. A kidney stone can pass through by itself or might be severe enough to require removal with surgery. Is drinking a lot of water good for your kidneys?
Water helps the kidneys remove wastes from your blood in the form of urine. Water also helps keep your blood vessels open so that blood can travel freely to your kidneys, and deliver essential nutrients to them. But if you become dehydrated, then it is more difficult for this delivery system to work.

How do doctors flush kidneys?
How does hemodialysis work? Hemodialysis is a procedure where a dialysis machine and a special filter called an artificial kidney, or a dialyzer, are used to clean your blood. To get your blood into the dialyzer, the doctor needs to make an access, or entrance, into your blood vessels.
Can urine back up into kidneys?
Each ureter has a one-way valve where it enters the bladder that prevents urine from flowing back up the ureter. But in some people, urine flows back up to the kidney. This is called vesicoureteral reflux. Over time, the kidneys may be damaged or scarred by this reflux.
What color is urine when your kidneys are failing?
When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
