The Association of Baseline Characteristics of Male Patients Presented With LUTS and Long Term Clinical Outcomes

February 18, 2021 updated by: Chi Fai NG, Chinese University of Hong Kong

A Retrospective Review of the Association of Baseline Characteristics of Male Patients Presented With Lower Urinary Tract and Long Term Clinical Outcomes

Non-neurogenic male lower urinary tract symptom (LUTS) is one of the most common symptom presented in urological clinic. Male LUTS could be a result of a combination of many different conditions, including benign prostate hypertrophy, overactive bladder, diabetes, noctural polyuria, sleep apnoea etc. Also male LUTS has shown to have close relationship with metabolic and cardiovascular conditions. Because of the increasing evidences to suggest a close relationship of cardiovascular condition and metabolic problems and male LUTS, this is a study to retrospective review of the patients assessed in this urology clinic and have a more in-depth assessment of the relationship of the baseline characteristics of these medical conditions with the presenting symptoms, as well as the long term urological and overall clinical outcomes of these patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a retrospective study.Male patients who presented with lower urinary tract symptom to our centre and assessed in the urology clinic from 2005 to 2019 would be enrolled to the study. This study will be conducted by observation; that is, data will be captured from medical records and central medical system (CMS), but patients will not be contacted. All the demographic and medical background, as well as investigations performed during the assessment including uroflowmetry, post-voiding residual, questionnaires, blood pressure, pulse, vascular assessment and blood result will be collected. Follow-up data including usage of medication, clinical outcomes (such as development of urinary retention, cardiovascular events, need of surgical intervention, mortality etc.) will be captured from the medical records.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

35 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Sampling Method

Non-Probability Sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The overall prevalence of adverse cardiovascular events (MACE) in male patients presented with lower urinary tract symptoms (LUTS)
Time Frame: Through study completion, an average of 2 years
Major adverse cardiovascular events such as myocardial infraction, ischemic heart disease, heart failure, coronary angioplasty etc. in male patients with LUTS. It is assessed by medical record
Through study completion, an average of 2 years
The overall prevalence of diabetes in male patients presented with lower urinary tract symptoms (LUTS)
Time Frame: Through study completion, an average of 2 years
It is assessed by medical record
Through study completion, an average of 2 years
The overall prevalence of dyslipidaemia in male patients presented with lower urinary tract symptoms (LUTS)
Time Frame: Through study completion, an average of 2 years
It is assessed by medical record
Through study completion, an average of 2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Correlation between nocturia and Central arterial stiffness (CAS)
Time Frame: Baseline
Nocturia is assessed by International Prostate Symptom Score Question 7, high value means worser nocturia; CAS is assessed by brachial-ankle PWV (baPWV), the value >1800cm/sec is highly associated with development of MACE
Baseline
Incidence of acute retention of urine
Time Frame: Through study completion, an average of 2 years
It is assessed by medical record
Through study completion, an average of 2 years
Incidence of requirement of surgical intervention
Time Frame: Through study completion, an average of 2 years
It is assessed by medical record
Through study completion, an average of 2 years
Overall mortality
Time Frame: Through study completion, an average of 2 years
It is assessed by medical record
Through study completion, an average of 2 years

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
