Urology and Nephrology

For the health of your kidneys and urinary tract, you may have to visit a urologist and a nephrologist separately. Many people get confused about the role of people in these two fields.

The urologists are the healthcare providers that take care of your urinary tract and perform operations related to kidneys. Like they will remove the cancer of the kidney, stones present in the kidneys and open up the blockage they cause.

While nephrologists are qualified experts who are specialized in kidney care. They are more focused to help your kidneys work better and maximize their potential. Also, they perform dialysis and monitor kidney functioning.

If you have a complaint of swelling in your hands and feet along with decreased urine output, you must visit the best urologist in Karachi.

Kidney disease

Kidney disease, also known as renal disease often do not show any symptoms, therefore it is often referred to as a silent killer. It is because when it shows symptoms, a lot of damage has already occurred. At the initial stages, it does not show such bothering symptoms. 

Generally, kidney diseases can be classified as acute kidney disease and chronic kidney disease.

Acute kidney disease

Its onset is sudden and causes decreased perfusion to kidneys, shock, dehydration, and decreased urine output. Mostly it occurs due to infections or autoimmune conditions. 

Chronic kidney disease

Its onset is gradual and takes time to show symptoms. 

Causes of Kidney Failure 

There are various causes of kidney failure. It can occur due to any of the following reasons.

  • Glomerulonephritis-that can occur due to any virus and bacteria.
  • Uncontrolled diabetes 
  • Uncontrolled hypertension 
  • Obesity 
  • Chronic kidney infections
  • Obstruction in the urinary tract 
  • Congenital problems in the structure and functioning of kidneys
  • Hepatorenal syndrome-kidney failure that occurs secondary to liver failure
  • Lupus nephritis 
  • Polycystic kidney disease

However, this list is not exhaustive. There may be other reasons too for kidney failure. Therefore visiting a doctor is a must if you feel any symptoms of kidney failure. 

Kidney failure is divided into five stages depending on the symptoms and damage it causes. Stage I is the mildest one, while stage V is the advanced one.

Symptoms of Kidney Disease

You must pay attention to the symptoms mentioned below, so if you have kidney disease, an early diagnosis can be made. 

High blood pressure

Kidneys play an important role in regulating blood pressure. If they are not working well, your blood pressure may raise. Therefore, if your blood pressure remains higher than normal you must consult with a healthcare provider about it. 

Changes in Urine Output and Color

You may notice a change in the color of your urine and urinating habits. The frequency of urinating may decrease or stop. Therefore, keep an eye on how many times you need to use the toilet in a day, as it can be an indication of an underlying cause.


We do not pay much attention if our body is swelled up a little. But it can be a sign of kidney disease. When your kidneys do not work well, they retain water and can not excrete it out, which leads to swelling. 

Nausea and vomiting 

The build-up of toxins and waste products in the body can cause nausea and vomiting. 

Brain fog

When toxins build up in the body and can not get out, they may reach the brain, causing confusion and bring fog. Also, you may feel more lethargic and lazy. 


All the above-mentioned symptoms may not appear simultaneously. One may go and another may come. Therefore, to be on the safe side, you must consult with a healthcare provider if you have any one of more of these symptoms. Doing that at the right time can help in early detection of the disease, through which management of the condition becomes easier.

If kidney failure is diagnosed at the last stage, the healthcare providers do not have much treatment to offer in this scenario. If your blood pressure remains elevated and urine output is decreased, you must visit a top urologist in Pakistan
