Signs & Symptoms
Recognize the early signs that indicate you may need medical attention
Weak Urinary Stream
Progressively weakening stream warranting objective measurement of flow rate.
Urinary Hesitancy
Difficulty initiating urination or prolonged time to start voiding.
Frequency & Nocturia
Frequent urination during the day and night interfering with normal activities and sleep.
Urgency & Incontinence
Sudden uncontrollable urge to urinate or leakage requiring urodynamic evaluation.
Post-Op Voiding Assessment
Monitoring urinary function after prostate surgery, urethral stricture treatment, or pelvic surgery.
Neurogenic Bladder
Bladder dysfunction from spinal cord injury, stroke, Parkinson's, or multiple sclerosis.
Common Causes & Risk Factors
Benign Prostatic Hyperplasia
Most common cause of reduced Qmax in middle-aged and elderly men.
Urethral Stricture
Scar tissue narrowing the urethra — produces a classic plateau or flat flow pattern on uroflowmetry.
Overactive Bladder
Detrusor overactivity causing urgency — urodynamics distinguishes OAB from obstruction.
Neurogenic Bladder Dysfunction
Spinal cord injury, diabetic neuropathy, or neurological disease causing variable voiding dysfunction.
Post-Surgical Changes
Altered voiding function after pelvic surgery, hysterectomy, or radical prostatectomy.
Treatment Options
Advanced minimally invasive techniques for better outcomes and faster recovery
Free Flow Uroflowmetry
Patient voids into the uroflowmeter — flow rate, voided volume, and curve pattern recorded.
Post-Void Residual (PVR)
Ultrasound bladder scan immediately after voiding to measure retained urine volume.
Cystometry / CMG
Filling and voiding pressure study to evaluate detrusor function, compliance, and sphincter activity.
Pressure-Flow Study
Simultaneous bladder pressure and flow measurements — distinguishes obstruction from underactive detrusor.
Benefits at Chahal Hospital
Non-Invasive
Basic uroflowmetry requires only that the patient voids into a specially fitted toilet — completely painless.
Rapid Results
Flow measurements and immediate interpretation available within 15–20 minutes.
Precise Diagnosis
Objectively quantifies urinary dysfunction, guiding the most appropriate treatment.
Treatment Monitoring
Compares pre- and post-treatment flow to objectively assess the effectiveness of surgery or medication.
Expert Interpretation
Dr. Ajay Chahal reviews all results in the context of your full clinical picture.
Same-Day Appointment
Uroflowmetry is available on the same day as your urology consultation.

Come to the clinic with a comfortably full bladder. Avoid urinating for 2–3 hours before the test. You will void normally into the uroflowmeter — do not strain or rush.
A normal maximum flow rate (Qmax) is > 15 mL/sec with a bell-shaped flow curve. Qmax < 10 mL/sec suggests significant obstruction. Values between 10–15 mL/sec are borderline.
Uroflowmetry is one component of urodynamic testing. Full urodynamics additionally includes cystometry (bladder pressure testing), electromyography, and sometimes video urodynamics — providing a more complete picture of bladder and sphincter function.
Uroflowmetry with PVR is recommended before prostate surgery. Full urodynamics is needed when the diagnosis is uncertain — for example, when neurological disease may be contributing to symptoms.
At least two flow tests are recommended to account for variability. A minimum voided volume of 150 mL is needed for reliable interpretation.
