NCT05508165

Brief Summary

This study is being done to compare usefulness of data collected in uroflowmetry, a test that measures the amount of urine released from the body, at home versus in the doctor's office. Additionally, investigators are assessing patient satisfaction when completing a virtual visit for lower urinary tract symptoms (LUTS), related to prostatic enlargement, compared to an in person visit. The three devices being investigated have not been used in the home setting to make urinary measurements as is typically done in clinic. The goal is to test the effectiveness and accuracy of these devices compared to our standard clinical practices and demonstrate their ability to provide useful information in the home setting.

Outcome Measures

Primary Outcomes (8)

  • International Prostate Symptom Score (IPSS) Baseline

    The IPSS assesses prostate related symptoms and their frequency of occurrence through seven questions, scored on a 6 point scale, from 0 (not at all) to 5 (always). Total symptom-related scores range from 1-7 (mild), 8-19 (moderate), and 20-35 (severe). The IPSS also assess quality of life due to urinary symptoms with a single question, scored on a 7 point scale (0 = delighted; 6 = terrible). The IPSS will be administered at the initial visit (baseline) for Cohorts 1a and 1b. Baseline scores will be compared between the two groups to evaluate for equivalency.

  • International Prostate Symptom Score (IPSS) Change

    The IPSS assesses prostate related symptoms and their frequency of occurrence through seven questions, scored on a 6 point scale, from 0 (not at all) to 5 (always). Total symptom-related scores range from 1-7 (mild), 8-19 (moderate), and 20-35 (severe). The IPSS also assess quality of life due to urinary symptoms with a single question, scored on a 7 point scale (0 = delighted; 6 = terrible). The IPSS will be administered at the initial visit (baseline) and Month 3 for Cohorts 1a and 1b. The amount of IPSS score reduction at the time of 3 month follow up will be compared between both groups to evaluate for equivalency.

    3 months

  • Uroflowmetry Baseline

    Uroflowmetry measures the flow of urine as milliliters (ml) of urine passed per second(s). Typical scores range between 5 and 20 ml/s, with a lower score indicating possible obstruction, enlarged prostate or weak bladder and a higher score indicating good flow. Cohort 1a will undergo in-person uroflowmetry per standard clinical assessment at Baseline. Standard clinical assessment includes measurement of a single void during the in-person clinic visit by urinating once into the uroflowmetry device (a urinal with calibrated sensors to measure flow). Cohort 1b will undergo uroflowmetry through at-home use of the Stream Dx device (also a urinal with calibrated sensors to measure flow), which includes measuring all voids performed at home during a 5 day period prior to Baseline (initial virtual visit). Baseline uroflowmetry assessment results for Cohorts 1a and 1b will be evaluated for equivalency.

Cohort 1b will undergo uroflowmetry through at-home use of the Stream Dx device (also a urinal with calibrated sensors to measure flow), which includes measuring all voids performed at home during a 5 day period prior to Baseline (initial virtual visit) and again during a 5 day period prior to the Month 3 follow up visit. Increase in average flow at 3 months on uroflowmetry for Cohorts 1a and 1b will be evaluated for equivalency.

    3 months

  • Post Void Residual (PVR) Baseline

    Post Void Residual is the amount of urine remaining in the bladder after voiding. Typical scores range between 0 and 150 mL, with a higher score indicating incomplete bladder emptying. Cohort 1a will undergo in-person PVR assessment per clinical standards once at Baseline. This includes measurement of a single PVR volume during the clinical in-person visit using a calibrated ultrasound based bladder scanner that is placed on the patient's lower abdomen for 5 seconds. Cohort 1b will undergo PVR assessment through at-home use of the DFree device, a wearable bladder scanner. Participants will wear this device for an entire day during which will collect PVR measurements after each void during that period prior to the Baseline visit (initial virtual visit). PVR results for Cohorts 1a and 1b at baseline will be evaluated for equivalency.

Reduction in PVR between each group at the time of 3 month follow up will be evaluated for equivalency.

    Baseline and 3 months

  • Urinalysis (UA) Baseline

    Urinalysis (UA) the urine for infection (UTI) or diabetes. Recorded outcomes will be possible UTI (any positive leukocyte esterase, nitrites, or blood) and possible diabetes (any positive glucose, ketones, or proteins). Cohort 1a will undergo a UA assessment per standard clinical assessment once at the initial visit (baseline). This includes dipping a urine sample with a test strip which is read by a machine during the clinic in-person visit. Cohort 1b will undergo a UA assessment per standard clinical assessment once at the first virtual visit (baseline). Using the Testcard phone app, the patient will collect a urine sample at home, and dip a test strip into the urine which is then analyzed by the mobile app. UA results for Cohorts 1a and 1b will be evaluated for equivalency between the two groups at baseline. Any positive results (UTI or diabetes) will undergo confirmatory lab testing per standard of care.

Study Arms (3)

Cohort 1a: in-person clinical assessment of LUTS/BPH

NO INTERVENTION

COHORT 1a: Subjects randomized to undergo in-person initial clinical workup of Lower Urinary Tract Symptoms (LUTS) / Benign Prostatic Hyperplasia (BPH) and in-person clinical follow-up after 3 months of clinical intervention. In-person clinical workup at both the initial and Month 3 follow-up timepoint includes International Prostate Symptom Score (IPSS), and standard of care uroflowmetry, post void residual (PVR), and urinalysis (UA) assessments.

Cohort 1b: virtual (telehealth) clinical assessment of LUTS/BPH

EXPERIMENTAL

COHORT 1b: Subjects randomized to undergo virtual initial clinical workup of Lower Urinary Tract Symptoms (LUTS) / Benign Prostatic Hyperplasia (BPH) and virtual clinical follow-up after 3 months of clinical intervention. Virtual clinical workup at both the initial and Month 3 follow-up timepoint includes at home completion of International Prostate Symptom Score (IPSS), at home uroflowmetry assessment through use of the Stream Dx device, at home assessment of post void residual (PVR) through use of the DFree device, and at home urinalysis (UA) through use of the TestCard device.

Cohort 2: Validation Cohort

OTHER

COHORT 2: Non-randomized subjects who will attend a single, clinically scheduled, in-person follow-up appointment to directly compare the standard of care assessments/devices to the experimental assessments/devices. Prior to the in-person appointment, patients will complete at home uroflowmetry assessment through use of the Stream Dx device. At the in-person appointment, the clinic staff will perform standard of care uroflowmetry, post void residual (PVR), and urinalysis (UA). At this visit, clinic staff will also obtain PVR measurements through use of the DFree device and urinalysis through the TestCard device.
