Detrusor Underactivity: Presentation and Urodynamic Characteristics

Completed

• Conditions: Detrusor Underactivity

• Registration Number: NCT04336280
• Lead Sponsor: Mutah University

Brief Summary

Detrusor underactivity (DU) is a known disease of the muscles of the urinary bladder that defined as a weak contraction of the muscle resulting in a failure to achieve complete bladder emptying. Recently, DU as a cause of Lower Urinary Tract Symptoms in both men and women has been increasingly gaining attention. There is a major issue in differentiation of underactive bladder symptoms and other causes of lower urinary tract symptoms such as detrusor hyperactivity and impaired contractility (DHIC), hypersensitive bladder (HSB), detrusor overactivity (DO), bladder outlet obstruction (BOO) and Dysfunctional Voiding (DV). Urodynamics (UDS) is 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. This study aims to determine the prevalence of DU along with its symptomatic and urodynamics (UDS) characteristics of DU in Jordanian population through a retrospective chart review.

Primary Outcome Measures

Name	Time	Method
Prevalence of detrusor underactivity in Jordan	3 years	The proportion of patients with lower urinary tract symptoms found to be affected by Detrusor underactivity
Urodynamics parameters	Each test takes around 30-45 minutes, all urodymanics studies were performed during the study period	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.
Symptomatic presentation of Detrusor underactivity	over one month period prior to clinical evaluation during the 3 years time period	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.
