Urodynamic Testing / Bladder Function Testing / Lower Urinary Tract Evaluation
Urodynamic Testing in La Mesa, CA
Bladder function testing for urinary incontinence, overactive bladder, urinary retention, weak urine stream, incomplete bladder emptying, enlarged prostate symptoms, urethral obstruction, sphincter problems, nerve-related bladder dysfunction, recurrent urinary symptoms, and treatment planning.
Urodynamic testing provides valuable data about bladder function and the lower urinary tract. The tests evaluate how well the bladder, urethra, and sphincter muscles work together while the bladder fills, stores urine, and empties.
Testing can show how the bladder fills, how much it can hold, and whether pressure rises abnormally.
Testing can measure urine flow, bladder pressure, obstruction patterns, and residual urine after voiding.
Results can help distinguish between bladder muscle problems, nerve-related issues, sphincter problems, and outlet obstruction.

Reasons for Urodynamic Testing
Urodynamic testing may be recommended when urinary symptoms are complex, persistent, unclear, or when more information is needed before treatment or surgery. Testing helps identify whether symptoms are caused by bladder storage problems, bladder emptying problems, outlet obstruction, sphincter dysfunction, nerve-related changes, or medication effects.
- Urinary incontinence or leakage
- Overactive bladder symptoms
- Frequent urination
- Urgent need to urinate
- Difficulty starting urination
- Weak or slow urine stream
- Incomplete bladder emptying
- Urinary retention
- Recurrent urinary tract infections related to emptying concerns
- Enlarged prostate symptoms
- Possible urethral obstruction or sphincter problems
- Nervous system conditions that may affect bladder control
- Planning before selected bladder, prostate, prolapse, or incontinence procedures
Testing may help identify stress incontinence, urge incontinence, overflow patterns, or mixed symptoms.
Testing can help evaluate urgency, frequency, leakage, and bladder contractions during filling.
Testing may help distinguish enlarged prostate obstruction from weak bladder muscle or nerve-related emptying problems.
Urodynamic testing is not required for every urinary symptom. A urologist may first recommend a history, physical exam, urinalysis, bladder diary, post-void residual measurement, imaging, cystoscopy, medication trial, or lifestyle changes depending on symptoms.
Types of Urodynamic Testing
Several different tests may be used to evaluate symptoms of the bladder and lower urinary tract. The series of tests may vary based on the individual’s symptoms, medical history, and initial test results.
Uroflowmetry
A uroflowmetry test measures the speed and volume of urine flow. This test is used to help determine whether the bladder muscle is weak, urine flow is obstructed, or emptying is abnormal.
Cystometrogram
A cystometrogram measures bladder pressure and capacity while the bladder fills. A catheter is placed in the bladder, and sterile water or fluid is added gradually until the patient feels bladder sensations such as first urge, strong urge, or the need to urinate.
Electromyography
An electromyography test measures activity of the muscles in and around the urinary sphincter. This test may help determine whether the urinary problem is related to nerve or muscle coordination.
Post-Void Residual Test
A post-void residual test, also known as a PVR test, measures the amount of urine left in the bladder after urination. This may be performed using ultrasound or by inserting a catheter into the bladder through the urethra.
Pressure-Flow Studies
Pressure-flow studies measure bladder pressure while urinating. These tests help distinguish urinary symptoms caused by obstruction from symptoms caused by a problem affecting the bladder muscles or nerves.
Leak Point Pressure and Leakage Testing
During some studies, leakage may be observed while the bladder is filled or while the patient coughs, bears down, or changes position. This can help evaluate stress incontinence or bladder pressure patterns.
Video Urodynamics When Needed
In selected cases, urodynamic testing may be combined with imaging to show bladder shape, bladder neck movement, reflux, obstruction, or other structural findings during filling and emptying.
Preparing for Urodynamic Testing
Preparation depends on the exact test being performed. Some tests may require preparation such as limiting fluid intake, arriving with a comfortably full bladder, keeping a bladder diary, or temporarily stopping certain medications before the procedure.
Tell the doctor about bladder medications, prostate medications, diuretics, antibiotics, blood thinners, and all supplements.
Urine testing may be done before urodynamics to check for infection, because active infection may affect timing or results.
A diary of fluid intake, urination times, leakage episodes, urgency, and pad use may help interpret symptoms.
- Follow office instructions about fluids before the test
- Ask whether to arrive with a full bladder
- Bring a list of medications and allergies
- Tell the office about fever, burning, UTI symptoms, or recent antibiotics
- Report pregnancy possibility when relevant
- Ask whether any bladder or prostate medications should be paused
- Bring prior test results, imaging, bladder diary, or catheter records if available
Do not stop prescription medications unless the physician or testing team specifically instructs you to do so.
What Happens During Urodynamic Testing
The exact process depends on which tests are ordered. Some urodynamic tests are simple and noninvasive, such as uroflowmetry. Others involve small catheters placed in the bladder and sometimes the rectum or vagina to measure pressure during filling and emptying.
Step 1: Symptom and Urine Review
The team may review urinary symptoms, recent infections, medications, and urine test results before testing begins.
Step 2: Emptying Measurement
The patient may urinate into a special device that measures urine flow rate, total volume, and flow pattern.
Step 3: Post-Void Residual Measurement
The amount of urine remaining in the bladder after urination may be measured with ultrasound or a catheter.
Step 4: Catheter Placement When Needed
For pressure testing, small catheters may be placed to measure bladder pressure and abdominal pressure during the study.
Step 5: Bladder Filling and Sensation Reporting
The bladder may be filled gradually with sterile fluid while the patient reports bladder sensations, urgency, discomfort, or leakage.
Step 6: Emptying and Pressure-Flow Measurement
The patient may be asked to urinate while pressure and flow are measured to help identify obstruction, weak bladder muscle, or coordination problems.
Urodynamic testing can feel awkward or uncomfortable, but the goal is to reproduce bladder symptoms safely so the physician can better understand why they happen.
Understanding Urodynamic Testing Results
Results help diagnose the cause and nature of a lower urinary tract problem. The physician reviews measurements such as urine flow rate, bladder capacity, bladder pressure, bladder sensation, leakage, sphincter activity, post-void residual, and pressure during urination.
Findings may show overactive bladder contractions, low bladder capacity, poor compliance, or stress leakage.
Findings may show obstruction, weak bladder muscle, poor coordination, or incomplete bladder emptying.
Results can guide medication, pelvic floor therapy, bladder retraining, catheter planning, prostate treatment, incontinence treatment, or surgery.
When Symptoms Are Caused by Obstruction
Pressure-flow testing may show that the bladder is generating pressure but urine flow is blocked or narrowed. This pattern may occur with enlarged prostate, urethral stricture, bladder neck obstruction, or other outlet problems.
When Symptoms Are Caused by Bladder Muscle or Nerve Issues
Testing may show weak bladder contraction, poor bladder compliance, detrusor overactivity, or coordination problems involving the bladder, sphincter, and nervous system.
When Results Are Used Before Surgery
Urodynamic testing may be helpful before selected procedures for incontinence, prolapse, enlarged prostate, urinary retention, or complex urinary symptoms so treatment can be matched to the true cause of the problem.
Risks and Comfort Considerations
Many urodynamic tests are low risk. Tests that involve catheter placement may cause temporary discomfort, burning, mild bleeding, or urinary tract infection. The care team will explain what to expect and how to monitor symptoms after testing.
- Temporary discomfort during catheter placement
- Mild burning with urination after testing
- Small amount of blood in the urine
- Urinary urgency or bladder irritation for a short time
- Urinary tract infection
- Urethral irritation or trauma
- Difficulty urinating after the test in uncommon cases
Some tests require small tubes to measure pressure, which may cause temporary urethral discomfort.
Instrumenting the urinary tract can slightly increase the risk of urinary tract infection.
Burning, urgency, mild spotting, or bladder discomfort may occur briefly after testing.
Call the office after urodynamic testing for fever, chills, worsening burning, inability to urinate, heavy bleeding, severe pelvic pain, foul-smelling urine, or symptoms that worsen instead of improving.
After Urodynamic Testing
Most patients can return to normal activities after testing unless told otherwise. The physician reviews the results and explains how the findings affect diagnosis and treatment options.
Drinking fluids may help reduce mild burning or irritation after catheter-based testing.
Watch for fever, worsening pain, inability to urinate, or symptoms of urinary tract infection.
Results may guide medication, bladder training, pelvic floor therapy, catheter plans, Botox, neuromodulation, or surgery.
