uroflowmetry

 [u″ro-flo´met-re]
the graphic representation of urinary flow, expressed as cubic centimeters per second; called also flow study and urinary flow study.

uroflowmetry

(ū″rō-flō′mĕ-trē)
Timed measurement of the rate of urination. Uroflowmetry is used to diagnose conditions that result in slow urinary output, e.g., bladder outlet obstruction resulting from enlargement of the prostate gland. The maximal volume of urinary flow over time is called the Qmax. A Qmax of less than 10 ml of urine/second is an indication of significantly reduced urinary output.

(11) In the present study, urethral stricture was defined as a Qmax <10 mL/s on uroflowmetry and the visibility of the stricture site on urethroscopy or urethrography.
Changes in uroflowmetry maximum flow rates after urethral reconstructive surgery as a means to predict for stricture recurrence.
Boys were told to void from a standing position into the uroflowmetry container and uroflowmetric parameters [Q.sub.max] (ml/sec), VT (sec), voided/expected volume ratio (VER), FC (bell shaped curve, staccato, interrupted, plateau), EMG activity during voiding, and post-void residual volume ratio (PVRR) were recorded.
Conclusion: The standing voiding position in healthy people influenced uroflowmetry findings, and was associated with higher flow rates.
Before the procedure, all patients were evaluated by clinical observation with measurement of IPSS and QoL scores, uroflowmetry ([Q.sub.max] and postvoid residual urine), PSA levels, and TRUS examination to calculate prostate volume (total and transition zone volume).
The global urodynamics equipment and disposables market segmentation is based on type of products (uroflowmetry equipment, cystometer, ambulatory urodynamics systems, electromyographs, video urodynamics systems, urodynamics disposables, air-charged catheters, water-filled catheters, infusion, extension & perfusion pump tubing set, and transducers set).
Cases of abnormal uroflowmetry significant residual urine volume, or neurogenic bladder can be considered as an indication for urodynamic testing.

They address the pathophysiology of bowel and bladder dysfunction; epidemiology, quality of life factors, psychological aspects, and neuropsychiatric disorders and genetic aspects; evaluation using urodynamics, uroflowmetry and postvoid residual urine tests, and other methods; behavioral, psychological, medical, and surgical treatments, including urotherapy, physiotherapy, biofeedback, pharmacotherapy, peripheral tibial nerve stimulation therapy, sacral nerve stimulation therapy, and botulinum toxin; the evaluation and management of nocturnal enuresis; and neurogenic bladder and bowel dysfunction.
Uroflowmetry performed 10 days after removal of the catheter showed a maximum flow rate (Qmax) of 7 mL/s, a mean flow rate (MFR) of 5 mL/s, urine volume of 150 mL and residual volume of >100 mL.
The non-catheterized NB patients (n=7) and children from the reference group underwent uroflowmetry (3 times to precise the outcomes), and averaged outcome was calculated.
