Diagnostic tests

Diagnostic tests that may be performed:

In order to try and establish the cause of your urinary symptoms one or more of the following tests may be carried out .The following information describes each test and how it may help in the diagnosis and treatment of your condation.

Voiding Diary

A voiding diary records the time of each void and the volume of urine voided. This information will helpful in determining the cause of urinary frequency and other bladder control problems

Download Voiding Diary


Patients are normally asked to fill in the diary over a 48 hour period at home


This set of questions is a good guide to the severity of a patients symptoms. It is also a good measurement of a patient’s response to various treatments.

Urinalysis (UA)

Urinalysis is a test that evaluates a sample of your urine .Testing of the urine Involving a number of tests examining the appearance, concentration and content of urine. It is used to detect and assess a wide range of disorders, including urinary tract infection, kidney disease and diabetes.

Abnormal results of a urinalysis often require additional testing and further evaluation to uncover the source of the problem.

Urinalysis may be performed:

  • As part of a routine medical exam or on admission to hospital
  • If you have signs of diabetes or kidney disease, or to monitor you if you are being treated for these conditions
  • To check for blood in the urine
  • To diagnose a urinary tract infection

Urine culture

A urine culture is a test to find and identify germs (usually bacteria) that may be causing a urinary tract infection (UTI). Urine in the bladder normally is sterile-it does not contain any bacteria or other

If the urine culture is positive, other tests may be done to help choose which antibiotic will do the best job treating the infection.

A urine culture may be done to:

  • Find the cause of a urinary tract infection (UTI).
  • To establish the best course of treatment best treatment for a UTI
  • It can also be used to establish whether treatment for a UTI worked.


Uroflow Test

With a full bladder you will be asked to void into a special bowel which can measure the voiding volume,the forcefulness of the urinary stream, the pattern of the urine flow, and the time taken to void It can help to diagnose obstruction of the urinary passages or poor bladder contractions, and is also used to determine bladder capacity.



Ultrasound is a form of imaging that may be carried to establish if the bladder is fully emptying after voiding. An ultrasound exam is carried out with the bladder full and again immediately after a patient voids

Ultrasound exam is also able to check the kidneys for stones or other abnormalities


Cystoscopy to inspect the inside of the bladder

This test involves visual examination of the inside of the bladder with a miniature fiber optic camera, which is passed through the urethra into the bladder. This is a minimally invasive procedure usually performed as a day case procedure under sedation or a general anesthetic enabling a detailed visual inspection to be performed without causing discomfort.

Visually inspecting the inside of the bladder can determine many causes of bladder problems, including bladder stones, tumors, endometriosis, or interstitial cystitis. It also allows us to determine the capacity of the bladder.


Urodynamic studies

This test is normally performed  to establish the best course of treatment for patients with urinary urgency, frequency, incomplete bladder emptying or incontinence.

Urodynamic is carried out to establish the function and pressure in the bladder as well as measuring the flow of urine through the urethra (the pipe which urine is passed out of the body). Urodynamics provides extremely important information on how much urine the bladder can hold ,highlight overactivity of the bladder the strength of the bladder and if there is any obstruction.

The procedure and what to expect:

This procedure involves a catheter being placed into the bladder through the urethra. This is to allow for the bladder to be filled during the procedure Another small catheter containing a pressure monitoring probe will be placed in the rectum(anus). The pressure monitor probe will be connected to a computer to record and measure the pressure of the bladder

Once the catheters are in place and the bladder has been emptied, you will be asked to lie flat  on a table while your bladder is slowly  filled with sterile water. The pressure in the bladder will monitored during this filling phase. You will be asked to cough  to see if urine leaks . The table will then be raised to an upright position while the bladder is still being filled This is part of the test as pressure in the bladder will differ between lying flat and standing upright. Once you are full or feel like you have to urinate, you will be asked to empty your bladder the volume of urine voided is recorded  and  the test is completed.

The test takes 30-45 minutes. At the end of the test, the catheters will be removed and you will be given antibiotics for a few days.
