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.
This study is being done to improve the availability of telehealth urology visits. In this study, investigators will compare the usefulness of data collected by three home devices to understand the amount of urine released from the body, how empty the bladder gets after urinating, and if there is an infection present in the bladder. These will be compared to being at home versus in the doctor's office. Additionally, the study will determine how satisfied patients are 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 standard clinical practices and demonstrate the ability of these devices to provide useful information in the home setting. The study involves two cohorts. Cohort 1 are new patients who will be randomized to either telehealth visits or in office visits. If randomized to the telehealth group, the patients will use various devices to perform a standard workup at home. If randomized to the clinic visit, similar tests will be performed in the office. Cohort 2 are existing patients who will use one of the devices at home, but will also complete similar in-office tests in order to compare device accuracy. Screening will be performed prior to patient's first scheduled visit based on chief complaints of urinary retention, BPH, or LUTS. Patients will be initially identified by study personnel or qualified research coordinator when the patient is identified to have qualifying issues through reviewing medical records of patients. Patient will be contacted by phone by the study personnel. If the patients are interested, the patients will be screened for inclusion criteria.

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.
Time frame: 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.
Time frame: 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.

Time frame: 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.

Urology Satisfaction with Outpatient Service (SWOPS) baseline
Patient satisfaction in Cohorts 1a and 1b will be measured with the validated Satisfaction with Outpatient Service (SWOPS) questionnaire following their initial visit (baseline). The questionnaire assesses the patient's satisfaction with their visit across 13 topics. The investigators will test non-inferiority in SWOPS scores between patients in the virtual group and in-clinic group at the initial visit. There is no defined scale or score that would suggest a better or worse outcome, rather the percent response of "Yes, definitely", "Yes, to some extent", and "No" to each of the 13 questions will be compared between the two groups for equivalency and thus the non-inferiority statistical approach was chosen.
