A Self-Administered Maneuver to Relieve Symptoms Suggestive of Benign Prostatic Hyperplasia

October 1, 2015 updated by: Kaiser Permanente

Study of a Self-Administered Maneuver to Initiate and Maintain Urine Flow Impeded by Benign Prostatic Hyperplasia

The objective of this study was to evaluate the effectiveness of the Digital Repetitive Infrapubic Pressure maneuver, a self-administered procedure used to provide symptomatic relief in initiating and maintaining urine flow impeded by benign prostatic hyperplasia.

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

Eligible patients were alternately assigned to either immediate instruction on the use of the Digital Repetitive Infrapubic Pressure maneuver (immediate intervention group) or to a return appointment to receive instructions in the maneuver four weeks after the initial assessment date (delayed intervention group). Patients were to utilize the procedure on every occasion they had difficulty initiating, maintaining, or completing urine flow between the time of their instruction and their subsequent visit. At the initial assessment visits and the final visit, the patients completed an International Prostate Score Sheet (IPSS). A telephone survey was conducted with all patients an average of nine months following their instruction in the maneuver, to determine the extent to which they were still using it.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

45 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • mild to moderate symptoms of difficulty initiating and maintaining the flow of urine
  • not currently receiving treatment for the condition
  • not taking an alpha-blocker at least one month before randomization
  • not taking 5-alpha reductase inhibitor six months or more before randomization.

Exclusion Criteria:

  • non-ambulatory
  • taking medications known to affect urination,
  • any of the following: a debilitating concomitant illness, a history of prostate or bladder cancer or prostate surgery or radiation treatment to the pelvis, urethral stricture, neurogenic bladder, current urinary tract infection or otherwise potentially compromised urinary tract systems, a creatinine level of over 3.0 mg per deciliter, or a residual urinary volume after voiding of over 350 cubic centimeters.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Immediate & Delayed Instruction
Male patients with mild to moderate lower urinary tract symptoms will alternately be assigned to either immediate intervention or delayed intervention groups. Statistical assessments will be performed to establish comparability of baseline characteristics in the two groups.
Behavioral: the Digital Repetitive Infrapubic Pressure maneuver
The Digital Repetitive Infrapubic Pressure maneuver is performed by exerting moderate inwards pressure with the index and middle fingers, spread slightly apart, palm-side up, pushing into the fold of skin at the base of the penis, where it comes forward beneath the pubic bones, one fingertip on each side of the penis' suspensory ligament. By repeatedly pushing inwards and slightly upwards, at a rate of about once per second, to a distance of about two centimeters, at times of significant urinary hesitancy it is often possible either to initiate spontaneous flow, or to pass a small quantity of urine with each push, such that after a minute or two one can empty the bladder to a satisfactory degree. While a few men find it useful when voiding in a standing position, for the majority, the maneuver requires a forward-leaning seated posture for optimal results.

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
Change in the International Prostate Symptom Score (IPSS)
Time Frame: The initial time frame was to average four weeks. There was a subsequent follow up time frame averaging nine months
The primary efficacy analyses compared the change over time in the IPSS scores between the immediate and the delayed intervention groups, and the changes over time between pre- and post-intervention scores for all patients completing the study.
The initial time frame was to average four weeks. There was a subsequent follow up time frame averaging nine months

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
Continued use of technique following intervention
Time Frame: Nine months after intial 4 week intervention
Secondary efficacy analysis: The number of patients (percentage of patients completing the study) who were still employing the technique on follow-up nine months later.
Nine months after intial 4 week intervention
