When to See a Urologist for Kidney Concerns

Your kidneys play a vital role in filtering waste, regulating fluid levels and maintaining the body’s mineral balance. When something affects kidney function, the signs can range from changes in urination and blood in the urine to persistent back or side pain, swelling or recurring urinary tract infections.
 

These symptoms may point to conditions such as kidney stones, infections or urinary blockages. A urologist can evaluate the underlying cause and recommend the appropriate treatment to help protect your kidney health.

Kidney Specialist or Urologist: Who Should You See?

A kidney specialist, also known as a nephrologist, focuses on diagnosing and managing conditions that affect kidney function. These may include chronic kidney disease, reduced kidney function, protein or blood in the urine, kidney inflammation and electrolyte imbalances.
 

A urologist focuses on the urinary tract and structural conditions affecting the kidneys and surrounding organs. They are often involved when symptoms are linked to kidney stones, urinary blockages, recurrent urinary tract infections or conditions that may require surgical or minimally invasive procedures.

Symptoms That Should Prompt a Visit to a Urologist

A urologist assesses symptoms affecting the kidneys, bladder and urinary tract. You should consider seeing one if you experience:

• Persistent Side or Back Pain: Pain below the ribs, especially on one side, may be linked to kidney stones, urinary blockage or other kidney-related concerns.
   

• Blood in the Urine: Pink, red or cola-coloured urine should be checked, as stones, infection, injury or other urinary tract conditions may cause it.
   

• Pain or Changes When Urinating: Burning, frequent urination, urgency or difficulty passing urine may suggest infection, irritation or obstruction.
   

• Recurring Urinary Tract Infections: Repeated infections may require further assessment to identify underlying causes, such as stones or urinary flow problems.
   

• Fever With Urinary or Flank Pain: Fever, chills, nausea or vomiting together with urinary symptoms or flank pain may indicate infection or blockage and should be assessed urgently.
   

A urologist can assess your symptoms, medical history and test results to identify the cause of urinary or kidney-related concerns. This may include urine tests, blood tests, ultrasound scans or CT scans.

What Kidney Conditions Does a Urologist Treat?

A urologist treats kidney-related problems that involve the urinary tract, especially conditions affecting urine flow, stones, infection, bleeding or structural changes.
 

Common kidney-related conditions treated by a urologist include:
 

• Kidney Stones

  Kidney stones are hard mineral deposits that can form in one or both kidneys. They may cause sharp side or back pain, blood in the urine, nausea, vomiting or pain when passing urine. A urologist can assess the stone’s size and location, then advise whether it can pass naturally or needs treatment.
   

• Ureteric Stones and Urinary Blockage

  Some stones move from the kidney into the ureter, which is the tube connecting the kidney to the bladder. If a stone gets stuck, it can block urine flow and cause pain, swelling of the kidney or infection. Treatment may be needed if the stone does not pass or if it affects kidney drainage.
   

• Blood in the Urine

  Blood in the urine, also called haematuria, should be assessed by a doctor. It may be linked to stones, infection, injury or other urinary tract conditions. A urologist may recommend urine tests, imaging or further checks to find the cause.
   

• Recurrent Kidney or Urinary Tract Infections

  Repeated infections may require further investigation, especially if they are associated with fever, flank pain, or kidney involvement. A urologist can check for stones, blockages or structural issues that may be contributing to recurring infections.
   

• Kidney Cysts, Growths or Tumours

  Kidney cysts or abnormal growths may be found during imaging scans. A urologist can assess whether these findings need monitoring, further testing or treatment.
   

• Structural Kidney or Urinary Tract Problems

  Some patients may have narrowing, blockage or abnormal drainage within the urinary tract. A urologist can investigate these issues and recommend treatment if they affect urine flow or kidney health.

In Singapore, patients may consult urologists such as Dr Damian Png, who practises at Mount Elizabeth Medical Centre. He manages urinary tract concerns, including kidney stones, prostate conditions and urinary strictures.
 

Do not delay seeking medical attention if symptoms persist, worsen or affect daily life. Early assessment can help identify the problem, relieve discomfort and guide suitable treatment, whether through medication, monitoring or a procedure.
