Epithelial Cells in Urine: Types ,Causes, Symptoms and Treatment.

 



Epithelial cells are specialized cells that form the lining of various structures in the body, including the skin, internal organs, and the urinary tract. Their presence in urine is common, as some shedding is normal. However, an excessive number may indicate an underlying health condition, such as a urinary tract infection (UTI), kidney disease, or inflammation. A urinalysis helps detect and analyze epithelial cells in urine, assisting in diagnosing infections, kidney disorders, or other medical conditions. Depending on the type and number of these cells, further medical evaluation may be necessary to determine the cause and appropriate treatment.

Types of Epithelial Cells in Urine

There are three main types of epithelial cells that can be found in urine:

  • Squamous Epithelial Cells: The most common type, originating from the urethra or external genitalia. A small number in urine is usually normal, but an excessive amount may indicate contamination or infection.
  • Transitional Epithelial Cells: Found in the bladder, ureters, and renal pelvis. An increased number may indicate an infection, inflammation, or bladder-related conditions.
  • Renal Epithelial Cells: Originating from the kidneys, their presence in urine could indicate kidney disease, tubular damage, or other renal conditions.

Causes of Epithelial Cells in Urine

The presence of epithelial cells in urine can be due to various reasons, including:

  1. Urinary Tract Infections (UTIs): Bacterial infections can cause inflammation and shedding of epithelial cells into the urine. Symptoms often include a burning sensation during urination, an urgency, and cloudy urine.
  2. Kidney Disease: Conditions like nephritis, glomerulonephritis, or chronic kidney disease may increase the number of renal epithelial cells.
  3. Inflammation of the Urinary Tract: Conditions such as interstitial cystitis or urethritis may cause an increase in epithelial cells due to irritation of the bladder lining.

  A sinus lift is one of the bone ridge-increasing procedures. It is to increase the amount of bone in the posterior jaw area. Ridge is the area where teeth are embedded in sockets.  There is a need for optimum ridge bone for a dental implant to be a success. Dental implants in the  top dental hospital in Bangalore  are used to replace both the form and function of missing teeth. It is a metal screw designed to thread into the jaw bone and allow for the attachment of various dental prosthetics.  What is a sinus lift?   A sinus lift is a procedure performed by the  best dental doctor in Bangalore  for ridge enhancement. It is used to treat the vertical loss of bone height and width of the available bone. Lack of sufficient bone height and maxillary sinus poses significant difficulty placing implants in the upper back region with missing teeth in the oral cavity.  Why are sinus lifts performed?  After upper jaw posterior tooth extraction, ...
