Arabic version of the International Prostate Symptom Score: Known and validated questionnaire to quantify and qualify the severity of symptoms of the lower urinary tract

Urodynamics: the standard diagnostic tool, it includes invasive recording of the pressure that is produced when the bladder muscle contracts via pressure sensors introduced in the urinary bladder through special types of urethral catheters.

The proportion of patients with lower urinary tract symptoms found to be affected by Detrusor underactivity

Arabic version of the International Prostate Symptom Score was used to assess the prevalence and severity of the symptoms that are associated with detrusor underactivity. The questionnaire includes 8 questions, the 1st 7 questions are about the urinary symptoms (Incomplete emptying, urinary frequency, intermittency, urgency, weak urine stream, straining and nocturia) and the 8th is about Quality of Life due to Urinary Symptoms. Each question concerning urinary symptoms allows the patient to choose one out of six answers indicating increasing severity of the particular symptom. The answers are assigned points from 0 to 5. The total score can therefore range from 0 to 35 (asymptomatic to very symptomatic). The answers to the 8th question (quality of life) range from "delighted" to "terrible" or 0 to 6.

Urodynamics is a series of tests conducted in an outpatient setting that evaluates the function of the urinary bladder, including physiological parameters of how completely the bladder, sphincter and urethra are storing and releasing urine. These parameters are recorded by pressure sensors that are inserted into the bladder via special urinary catheters to measure the pressure that is generated during storing and releasing urine. The assessment of urodynamic variables is based on bladder capacity, presence of involuntary bladder muscle contractions, bladder volume at 1st sensation of bladder filling, bladder volumes at normal and strong desire for urination, detrusor pressure at maximum flow of urine during voiding, volume voided, and the post-void residual urine volume. All urodynamic testing was performed based on the International Continence Society standards.
