ABSTRACT

INTRODUCTION: The purpose of this study was to gather initial safety and efficacy data with the Optilume BPH Catheter System for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). METHODS: A total of 80 men with moderate-to-severe LUTS secondary to BPH were enrolled and treated with the Optilume BPH Catheter System. Symptoms were evaluated using the International Prostate Symptom Score (IPSS) and Benign Prostatic Hyperplasia Impact Index (BPHII). Improvement in urinary flow and relief of obstruction was evaluated by way of peak urinary flow rate (Qmax) and postvoid residual urine volume (PVR). Subjects were prospectively queried for adverse events at each study visit, and relatedness to the study device were evaluated by the investigators, as well as centrally adjudicated by the study principal investigator. RESULTS: Previous reports of symptom improvement in this cohort were maintained through four-year followup, with a significant reduction in IPSS and IPSS quality of life maintained through four years (-12.1, -2.8, respectively). Clinically meaningful improvement in Qmax was maintained in the majority of subjects, with an average improvement from baseline of +5.6 mL/sec. No treatment-related adverse events were reported in the long-term followup period. CONCLUSIONS: Long-term followup through four years for subjects treated with the Optilume BPH Catheter System indicates durable outcomes in symptom improvement and functional improvement in flow rate. These results indicate the unique mechanism of action for Optilume BPH successfully achieves an immediate mechanical effect that is maintained long-term through incorporation of paclitaxel to maintain patency.

ABSTRACT

BACKGROUND: The surgical landscape for Lower Urinary Tract Symptoms (LUTS) and Benign Prostatic Hyperplasia (BPH) has evolved with the introduction of Minimally Invasive Surgical Therapies (MISTs), recognizing the impact of sexual function on patients' well-being, and prioritizing ejaculation-sparing approaches. METHODS: This systematic review explored ejaculation sparing after classic endoscopic procedures and MISTs (iTind, Rezum, Urolift, Aquablation, and TPLA) and a literature search yielded 41 studies. RESULTS: While all procedures demonstrated efficacy in improving LUTS/BPH symptoms (IPSS, QoL, Qmax), a subset of studies evaluated ejaculatory function. Positive outcomes were noted, challenging the historical association of BPH surgeries with ejaculatory dysfunction. Variations in study design, patient cohorts, and limited long-term data present challenges. Notably, the lack of baseline specificity, use of alpha-blockers, and non-specific sexual function assessments underscore potential biases. CONCLUSIONS: Despite limitations, the review tentatively concluded that MISTs, including iTind, Rezum, Urolift, Aquablation, and TPLA, appear comparable in sparing ejaculation. Long-term studies are essential to validate sustainability, and comparative research should assess trade-offs between MISTs and traditional surgeries. Incorporating patient-reported outcomes and quality of life assessments will enhance future investigations, refining MISTs as standard therapeutic options for LUTS/BPH.

ABSTRACT

OBJECTIVE: To examine how representative 24-hour data collection is of the overall patient experience utilizing a home uroflow device in men with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Home uroflow data were collected with the iO Urology CarePath device from men at a single urology clinic and retrospectively analyzed. Void characteristics were summarized for data collected over 24 hours compared to data collected over several days or weeks with the device (overall study excludes the 24-hour data). A linear mixed-effects model was used to evaluate differences in average Qmax from voids collected during a single 24-hour period compared to the overall study. RESULTS: A total of 486 men (mean age 67.4) used the device resulting in 465 included in the analysis with a total of 15,521 voids in the overall study and 4347 voids in the single-day analysis. Average Qmax from the model was 11.2 mL/s (95% CI: 10.80, 11.65) and 11.2 mL/s (95% CI: 10.81, 11.64) in the 24-hour and overall study groups, respectively. Both groups had similar between (20.3% vs 20.4%) and within-subject (12.0% vs 11.9%) variance. The difference in Qmax was not significantly different (P = .970). A subgroup analysis including voids >150 mL yielded similar results. CONCLUSION: Data show variability in voiding parameters, but similar average Qmax collected in 24 hours as compared to several days/weeks. The combination of home uroflowmetry with frequency-volume chart information can provide objective data and a unique perspective on uroflow variability (UFV) for clinician review to support the development of individualized patient treatment plans.

ABSTRACT

BACKGROUND: Patient outcomes were assessed 2 years after treatment with the Optilume BPH Catheter System, a minimally invasive surgical therapy for the treatment of lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). METHODS: One-hundred forty-eight adult males with symptomatic BPH were enrolled and randomized in a 2:1 fashion to Optilume BPH or Sham (100 Optilume BPH; 48 Sham). Long-term measures include International Prostate Symptom Score (IPSS), peak urinary flow rate (Qmax), Post-Void Residual Urine (PVR), quality of life measures and sexual function. Follow-up beyond one year was limited to those treated with Optilume BPH. RESULTS: At 2 years, 67.5% (56/83 CI 56.3%, 77.4%) of participants in the Optilume BPH arm were symptomatic responders as defined by ≥30% improvement in IPSS without medical or surgical retreatment. IPSS significantly improved from 23.4 ± 5.5 (n = 100) to 11.0 ± 7.0 (n = 74). Qmax improved by 116.8.% (8.9 ± 2.2 (n = 97) to 19.0 ± 16.3 (n = 65)), while PVR showed a slight reduction (83.7 ± 70.3 (n = 99) to 65.9 ± 74.5 (n = 65)). Improvement in uroflowmetry measures was consistent across all prostate volumes. BPH-II improved from 7.0 ± 2.9 (n = 98) to 2.3 ± 2.5 at 1 year (n = 89) and remained consistent at 2.3 ± 2.9 at the 2-years (n = 74), representing a 53.9% improvement. IPSS QoL also improved from 4.6 ± 1.3 (n = 100) at baseline to 2.2 ± 1.5 (n = 74). The most common adverse events reported in the Optilume BPH arm were hematuria and urinary tract infection (UTI). No device and/or treatment related serious adverse events were reported occurring beyond 12 months post-procedure. There was no impact to sexual function. CONCLUSIONS: In the PINNACLE study, participants treated with the Optilume BPH Catheter System demonstrated continued and durable results at 2 years, affirming tolerability, safety, and the enduring effectiveness. The Optilume BPH Catheter System provides lasting results that are comparable to the more invasive therapies, while preserving the advantages with being a minimally invasive therapy.

ABSTRACT

PURPOSE: The Optilume BPH Catheter System is a novel drug/device combination minimally invasive surgical therapy for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia. The PINNACLE study is a prospective, randomized, double-blind, sham-controlled clinical trial evaluating the safety and efficacy of Optilume BPH against a sham surgical procedure. MATERIALS AND METHODS: Eligible patients were men 50 years or older with symptomatic benign prostatic hyperplasia and a prostate size between 20 and 80 g. Subjects were randomized 2:1 to receive treatment with Optilume BPH or a sham surgical procedure. Blinding was maintained for subjects in both arms and evaluating personnel through 1 year postprocedure. Follow-up assessments included the International Prostate Symptom Score, uroflowmetry, and other quality-of-life and sexual function assessments. RESULTS: A total of 148 men were randomized (100 active, 48 sham) at 18 centers in the U.S. and Canada. Subjects randomized to receive Optilume BPH saw a reduction in International Prostate Symptom Score of 11.5±7.8 points at 1 year posttreatment, as compared to a reduction of 8.0±8.3 points at 3 months in the sham arm. Flow rate was dramatically improved after treatment with Optilume BPH, with an improvement of +10.3 mL/s from baseline to 1 year (+125%). CONCLUSIONS: Treatment with Optilume BPH provides immediate and sustained improvements in obstructive symptoms and flow rate while preserving erectile and ejaculatory function. Treatment is well tolerated and can be done in an office or ambulatory setting.

ABSTRACT

PURPOSE: To evaluate the safety and efficacy of the Optilume BPH Catheter System for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). METHODS: This open-label, single-arm study enrolled eighty subjects with LUTS secondary to BPH who were treated with the Optilume BPH Catheter System. Symptoms were recorded utilizing the International Prostate Symptom Score (IPSS) and Benign Prostatic Hyperplasia Impact Index (BPH-II). Functional improvement was measured utilizing peak urinary flow rate (Qmax) and post-void residual urine volume (PVR). Adverse events were systematically captured and reported at each follow-up visit. RESULTS: Subjects treated with the Optilume BPH Catheter System experienced a significant improvement in LUTS from baseline through 2 years of follow-up, as measured by IPSS (22.3 vs 8.2, p < 0.001) and BPH-II (6.9 vs 2.3, p < 0.001). Functional improvement was also significant, with Qmax improving from an average of 10.9 mL/s at baseline to 17.2 mL/s at the 2-year follow-up and PVR improving from 63.1 to 45.0 mL. Treatment-related adverse events were typically minor, with none occurring between 1- and 2-year post-treatment. CONCLUSIONS: The Optilume BPH Catheter System is a unique minimally invasive surgical therapy that combines mechanical and pharmaceutical aspects for the treatment of BPH. The functional and symptomatic improvements seen after treatment are significant and have been sustained through 2 years in this early feasibility study. REGISTRATION: NCT03423979, registered February 6, 2018.

ABSTRACT

BACKGROUND: Outcomes of radical prostatectomy (RP) in men with history of lower urinary tract symptoms related to benign prostatic enlargement (LUTS/BPE) surgery represents a controversial issue. We performed an updated systematic review and meta- analysis evaluating oncological and functional outcomes of RP in this subset of patients. METHODS: Eligible studies were identified from MEDLINE, Web of Science and the Scopus databases. The following outcomes were evaluated: incidence of positive surgical margins (PSM), incidence of biochemical recurrence (BCR), 3-mo and 1-year urinary continence (UC) rates, incidence of nerve-sparing (NS) procedures, 1-year erectile function (EF) recovery rates. We estimated pooled Odds ratios (OR) and 95% confidence intervals (CI) using random effects models. Sub-analyses were performed according to the type of RP and LUTS/BPE surgery. RESULTS: Twenty-five retrospective studies including 11,101 patients undergoing RP were included in the analysis (2113 with history of LUTS/BPE surgery, and 8898 controls). PSM rate was significantly higher in patients with history of LUTS/BPE surgery (OR 1.39, 95% CI 1.18-1.63, p < 0.001). No statistically significant difference in terms of BCR emerged between patients with or without history of LUTS/BPE surgery (OR 1.46, 95% CI 0.97-2.18, p = 0.066). Three-months and 1-year UC rates were significantly lower in patients with previous LUTS/BPE surgery (OR 0.48, 95% CI 0.34-0.68, p < 0.001 and OR 0.44, 95% CI 0.31-0.62, p < 0.001; respectively). Although not statistically significant differences between the two groups emerged in terms of adoption of NS procedures (OR 0.59, 95% CI 0.32-1.12, p = 0.107), 1-year EF recovery was significantly lower in patients with history of LUTS/BPE procedures (OR 0.60, 95% CI 0.40-0.89, p = 0.010). CONCLUSIONS: In conclusions, RP in patients with history of previous LUTS/BPE surgery is associated with increased incidence of PSM, lower UC rates at both 3-months and 1-year follow-up as well as lower rates of EF recovery at 1-year follow-up.
