Mean International Prostate Symptom Score (IPSS) at 3 Months Follow-up Visit
Query!
Assessment method [1]
0
0
The primary effectiveness objective was to demonstrate that mean IPSS improvement (? IPSS) following treatment with the prostaFix System exceeded 6.5 points with 95% confidence 3 months after treatment.
The International Prostate Symptom Score (IPSS) is a validated questionnaire used to assess baseline and post treatment BPH symptoms. It is based on the answers to seven questions concerning urinary symptoms and one question concerning quality of life. Each question concerning urinary symptoms allows the subject to choose one out of six answers indicating increasing severity of that 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): Mild (symptom score less than or equal to 7), Moderate (symptom score range 8-19) and Severe (symptom score range 20-35). Improvement in BPH symptoms is seen as a decrease in IPSS.

The primary safety objective of this study was to estimate the proportion of subjects affected by serious adverse events (SAEs) associated with the use of the device. This objective was addressed through recording all adverse events (AEs) observed or reported during the course of the study.

Question eight of the IPSS questionnaire refers to the subject's perceived quality of life (QOL). The International Scientific Committee (SCI), under the patronage of the World Health Organization (WHO) and the International Union Against Cancer (UICC), recommends the use of only a single question to assess the quality of life. The answers to this question range from "delighted" to "terrible" or 0 to 6.

Mean Change in Peak Flow Rate (Qmax) From Baseline

Assessment method [2]
0
0
Uroflowmetry measures the flow of urine. It tracks how fast urine flows (peak flow rate - Qmax), how much flows out, and how long it takes. It's a diagnostic test to assess how well the urinary tract functions. Uroflowmetry is used in BPH subjects to help the doctors determine how well the subject's urinary tract is doing and the severity of obstruction caused by the prostate. The higher the Qmax is, the less obstructed the urethra.

Mean Change in Post Void Residual (PVR) From Baseline

Assessment method [3]
0
0
The Post Void Residual (PVR) is an indicator of urine remaining in the bladder after voiding. A healthy bladder should be fairly empty following urination. A volume < 50 mL is normal; < 100 mL is usually acceptable in patients > 65 years old. The higher the PVR, the more urine is left in the bladder and this can be seen as a sign of increased obstruction of the urethra.

Mean Change in MSHQ-EjD Score From Baseline

Assessment method [4]

0
The MSHQ-EjD Short Form (Male Sexual Health Questionnaire - Ejaculatory Disfunction) is composed of three questions that rate ejaculatory function in men. A fourth question measures the MSHQ-EjD Bother, this asks the subject if he is bothered by his level of ejaculatory function.
MSHQ-EjD total score ranges from 1 to 15 with a higher score indicating better sexual functioning. MSHQ-EjD bother score ranges from 0 to 5 with a higher score indicating greater bother. An increase in the MSHQ-EjD Total Score indicates better ejaculation and a decrease in the MSHQ-EjD Bother Score means that the subject is less bothered by his ejaculatory function. Due to the sensitive nature of the questions, this questionnaire is voluntary and not all subjects completed it at baseline. Some subjects completed at baseline but decided not to complete at certain follow-up visits which explains the different number of participants during various analysis time frames.

The IIEF (International Index of Erectile Function) provides a broad measure of sexual function; an increase in score indicates an improvement in sexual function. This questionnaire consists of five questions that asks the subject of any erection problems that have impacted his sexual life over the past 4 weeks or since the last study visit, whichever is shorter. IIEF total score ranges from 0 to 25 with a higher score indicating better sexual functioning and an increase in score indicates an improvement in sexual function. Due to the sensitive nature of the questions, this questionnaire is voluntary and not all subjects completed it at baseline. Some subjects completed at baseline but decided not to complete at certain follow-up visits which explains the different number of participants during various analysis time frames.

MRI Necrosis Volume

Assessment method [12]

The prostaFix System uses pH shifts induced by water electrolysis to induce necrosis in the hyperplastic prostate tissue. The induced necrosis within the borders of the prostate result in a pressure reduction and thereby relieve the symptoms of BPH. This necrosis that resulted from the procedure eventually heals and necrosis volume should reduce overtime. Per protocol, only the first 10-15 subjects would have MRI studies at done to assess subject safety and treatment effect. then MRI was optional. A total of 14 subjects actually had an MRI and the results are reported for those subjects.
