McVary KT, Roehrborn CG. Three-Year Outcomes of the Prospective, Randomized Controlled Rezūm System Study: Convective Radiofrequency Thermal Therapy for Treatment of Lower Urinary Tract Symptoms Due to Benign Prostatic Hyperplasia. Urology 2017; 111:1-9. [PMID: 29122620 DOI: 10.1016/j.urology.2017.10.023] [Citation(s) in RCA: 80] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2017] [Revised: 10/16/2017] [Accepted: 10/26/2017] [Indexed: 01/15/2023]
Abstract
OBJECTIVE To report 3-year outcomes of a prospective, multicenter, randomized, blinded control trial after treatment with convective radiofrequency (RF) water vapor thermal therapy for moderate to severe lower urinary tract symptoms due to benign prostatic hyperplasia (BPH). MATERIALS AND METHODS Fifteen centers enrolled and randomized 197 men ≥50 years old with International Prostate Symptom Score (IPSS) ≥13, maximum flow rate (Qmax) ≤15 mL/s, and prostate volume 30 to 80 cc to thermal therapy with Rezūm System or control (2:1). Rigid cystoscopy with simulated active treatment sound effects served as the control procedure. Convective RF thermal energy was delivered into obstructive prostate tissue including the median lobe as needed. After randomized comparison at 3 months, thermal therapy subjects were followed annually for 3 years. RESULTS Convective RF thermal therapy yielded IPSS improvement of 160% compared with control subjects at 3 months (P <.0001). Maximal symptom relief of at least 50% improvement in IPSS, quality of life, Qmax, and BPH Impact Index remained durable throughout 3 years (P <.0001). Subjects with a treated median lobe had similar responses. No late-related adverse events occurred, and no de novo erectile dysfunction was reported. The surgical retreatment rate was 4.4% over 3 years. CONCLUSION The minimally invasive convective RF thermal therapy is an office or ambulatory outpatient procedure with minimal transient perioperative side effects. It provides early effective and durable relief of BPH symptoms with preservation of sexual function in subjects followed up for 3 years and is applicable to treatment of the median lobe and hyperplastic central zone tissue.

Abstract
Résumé
Objectif
Évaluer prospectivement les résultats fonctionnels de la thermothérapie prostatique par radiofréquence (Prostiva©) sur la gêne urinaire et la vie sexuelle dans le cadre du traitement d’une hypertrophie bénigne de la prostate (HBP) symptomatique non compliquée résistante aux traitements médicamenteux.
Patients et méthodes
Les patients répondant aux critères d’éligibilité à ce traitement édités selon la HAS ont été traités dans notre unité d’urologie. Ils ont été convoqués de façon systématique à un mois pour un examen clinique et paraclinique (débit urinaire maximum [Qmax], résidu postmictionnel [RPM], International Prostate Symptom Score [IPSS]). Ils ont été contactés en décembre 2009 et soumis à un hétéroquestionnaire téléphonique portant sur des scores de gêne urinaire (IPSS), de qualité de vie (question 8 de l’IPSS), d’évaluation des fonctions sexuelles (IIEF, DAN SEX), et d’évaluation subjective du traitement (échelle de Likert).
Résultats
De décembre 2006 à janvier 2009, 20 patients (âge médian: 63 ans) ont été traités par Prostiva©. Quatre patients ont présenté une rétention aiguë d’urine dans le postopératoire immédiat nécessitant un sondage vésical en urgence. Nous avons réalisé l’évaluation systématique de l’ensemble des patients à un mois et en décembre 2009. Le suivi médian était de 20,6 mois (valeurs maximales [12–37 mois]). On a constaté une amélioration significative de l’IPSS (−6,7 points; IC95= [−10,3; −3,1]), une amélioration des fonctions sexuelles, des scores de qualité de vie, et un sentiment d’amélioration globale des symptômes urinaires (+ 1,08 = amélioré sur l’échelle de Likert). Quatre patients ont été considérés comme des échecs du Prostiva©: trois patients ayant repris un traitement médicamenteux, un patient ayant bénéficié d’une résection de la prostate.
Conclusion
Notre étude monocentrique réalisée chez des patients sélectionnés selon les critères de l’HAS a conforté les résultats de la littérature avec des résultats positifs sur la gêne urinaire, une faible morbidité et une amélioration de la qualité de vie déclarée. Elle a démontré l’innocuité de la thermothérapie sur la sexualité des patients et mieux encore, l’impact positif du traitement sur la qualité des érections et la satisfaction des rapports.

Abstract
PURPOSE To evaluate the efficacy and morbidity of BPH treatment by radiofrequency in the general population and attempt to identify factors of prognostic value for this technique. METHODS This retrospective study examined 76 consecutive patients of mean age 68.9 years with symptomatic BPH in failure of medical treatment and treated at University Hospital of Caen between April 2004 and October 2008. Urine status was assessed before and after treatment with radiofrequency by the international prostate symptom score (IPSS), the quality of life (QOL) score related to urinary symptoms, the measurement of maximum urinary flow (Qmax) and residual postvoid volume (RPV). Erectile function was assessed by the International Index of Erectile Function (IIEF-5). The primary endpoint was treatment failure by radiofrequency regarded as the reintroduction of medical treatment or the need for surgical treatment. The secondary endpoints were the improvement of IPSS and QOL score, Qmax and RPV. Morbidity per and post-operative was also evaluated. RESULTS A significant improvement in voiding status was observed with an average IPSS score from 24.7 to 15.1 (P<0.0001), and a QOL score from 5.2 to 2.9 (P<0,0001) in all patients. The Qmax and the RPV were significantly improved from 8.6 to 13.1ml/s (P<0.0001) and 177 to 100ml (P=0.0002) respectively. The IIEF-5 score was improved from 9.04 to 9.97 (P=0.0164). Twenty-five percent of acute urinary retention, 7.9% of haematuria and 1.3% of prostatitis were observed postoperatively. The overall retreatment rate was 46% after 14.6 months mean follow-up. When stratified into groups, patients with the inclusion criteria to this treatment showed a treatment rates of 34.8% after 16.2 months mean follow-up against 51% after 13.8 months of monitoring patients outside the inclusion criteria. Without showing significant difference between retentionist and no retentionist concerning subjective and objective parameters, the rate of retreat was more important for retentionist (51.2% after 11.8 months of mean follow against 39.4% after 18.4 months) with a significant difference on the actuarial cumulative survival curve without reprocessing. There was no significant difference found in patients with a median lobe. The results showed an improvement in Qmax significantly greater in the group with prostates less than 60 g without being able to demonstrate significant differences in other parameters. The retreatment rates in this group was 44.4% after 14.7 months of follow-up against 53.8% after 13.8 months of follow-up in the group of patients with prostate over 60 g. Moreover, the irritative component made a better initial response to treatment with a need for retreatment delayed compared to the group of patients with obstructive symptom, without noting significant differences in terms of improvement of objective and subjective parameters. The rate of retreatment was 63.6% after 16.4 months of mean follow and 51.6% after 11.2 months in the "obstructive" group. CONCLUSION High rates of reprocessing are observed in the treatment of BPH by radiofrequency if inclusion criteria are not respected.

Abstract
Benign prostatic hyperplasia (BPH) is a common disease affecting a large proportion of men older than 50 years. There are multiple treatment options for BPH including medications, minimally invasive options such as transurethral needle ablation (Tuna) and transurethral microwave therapy (TUMT), and more invasive options such as transurethral laser vaporization and transurethral resection of the prostate (TURP). The minimally invasive options induce thermal injury to the BPH adenoma with a lower risk of permanent side effects than TURP. Tuna treatment is a minimally invasive technique of BPH which can be carried out in ambulatory surgery and which is effective for urinary symptoms with little risk of morbidity. It is an alternative to medical treatment and does not replace planned surgical treatment. Available evidence suggests that Tuna is a relatively effective and safe technique. It significantly improves BPH parameters but it does not reach the same level efficacy and long-lasting success as TURP. Also the Tuna procedure compares favourably to combination medical therapy for the treatment of BPH on a cost basis. α-Blocker monotherapy is less costly than Tuna for 5 years, while the cost of 5α-reductase inhibitor monotherapy is approximately equivalent to that of Tuna for 5 years. From the payer's perspective, the break-even point between the Tuna(®) procedure and combination medical management occurs after approximately 2 years 7 months of treatment.

Abstract
PURPOSE We analyzed the adverse event profile, long-term efficacy and cost-effectiveness of transurethral needle ablation of the prostate for lower urinary tract symptoms associated with benign prostatic hyperplasia as an alternative to transurethral resection of the prostate in men with symptoms uncontrolled by medical therapy. MATERIALS AND METHODS A total of 71 men on a waiting list for transurethral resection of the prostate after failed medical therapy underwent transurethral needle ablation of the prostate. Symptom scores, uroflowmetry and residual urine were measured before and up to 10 years following treatment. Transrectal ultrasound and pressure flow studies were performed before, and 3 and 12 months following treatment, respectively. Treatment failure was defined as lower urinary tract symptoms progression requiring further therapy or associated with deteriorating quality of life assessment. RESULTS Apart from transient postoperative urinary retention, no significant treatment emergent adverse events due to transurethral needle ablation of the prostate were observed. Treatment failure occurred in 58 men (83%) at a median of 20 months. A total of 36 men (51%) underwent invasive treatment (transurethral resection of the prostate 33, bladder neck incision 2, microwave thermal ablation 1), 2 men (3%) were deemed unfit for anesthesia and now practice clean intermittent self-catheterization, 14 men (20%) reported improvement following resumption of treatment with an alpha-adrenergic antagonist after transurethral needle ablation of the prostate and 6 men (9%) have experienced deterioration in lower urinary tract symptoms with reduction in quality of life assessment (International Prostate Symptom Score 3 or greater) but have declined further intervention. There were 12 men (17%) who remained symptom-free up to 10 years after transurethral needle ablation of the prostate. The estimated additional cost of treatment for lower urinary tract symptoms per man treated with transurethral needle ablation of the prostate during the 10-year followup was $1,377. CONCLUSIONS Despite documented safety and lack of morbidity, the high re-treatment rate associated with transurethral needle ablation of the prostate renders it relatively expensive when viewed as a long-term alternative to transurethral resection of the prostate for the management of lower urinary tract symptoms associated with benign prostatic hyperplasia in men in whom medical therapy failed. Of men failing alpha-blockade therapy 20% will benefit from a combination of transurethral needle ablation of the prostate and alpha-blockade.

Abstract
Medical therapy is currently the most popular treatment choice for lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Because medical therapy of BPH-related LUTS is considered a life-long strategy, short- and long-term cost considerations should play a major role in therapeutic decision-making. The effectiveness in terms of long and short amelioration of symptoms, flow rate, and quality of life are well documented for 5alpha-blockers and 5alpha-reductase inhibitors as well as for the gold standard treatment for BPH, transurethral resection of the prostate and minimally invasive therapies. Short- and long-term safety concerns also are well documented for these various treatment options. On the contrary, short- and long-term costs have been less well studied and comparisons depend on the model or analyses undertaken in the few studies available. However, the economic studies based on prospective clinical trial data that have become available throughout the past several decades allow us to rationalize our use of alpha- blockers, 5alpha-reductase inhibitors, and combination therapy, taking into consideration age, severity of symptoms, prostate volume, prostate-specific antigen, and the differential response of the various medications (and combination) in selected patients. Based on current studies, 5alpha-blockers generally provide cost-effective therapy for most patients, whereas 5alpha-reductase therapy and combination therapy provide cost-effective treatment for patients with larger prostate glands or higher baseline prostate-specific antigen levels.

Abstract
Throughout the past several decades, interest in health care economics has increased as health care spending has soared--currently in excess of 1.5 trillion dollars and comprising approximately 16% of the nation's Gross Domestic Product. Benign prostatic hyperplasia (BPH) and its associated clinical manifestation of lower urinary tract symptoms is one of the most common medical conditions of aging men. BPH has been, and continues to be, a major factor in health care expenditures in the United States, costing up to 4 billion dollars each year. During the past 15 years, considerable changes in the patterns of care for BPH patients have evolved, resulting in similarly profound economic alterations. In this article, we examine contemporary trends in practice patterns for BPH and their associated impact on the cost of care for this condition.

Abstract
Transurethral needle ablation (TUNA) of the prostate is an alternative treatment for benign prostatic hyperplasia (BPH) generating temperatures around 100 degrees C leading to necrotic lesions inside the prostate. TUNA is a minimally invasive, low morbidity associated, approach that uses radiofrequency energy. The needles are covered by teflon shields that protect the urethra from thermal injury. Since the introduction of TUNA, there has been a constant upgrading of the device to improve treatment quality. The main advantage of this therapy is the possibility of an outpatient care due to its anaesthesia-free option with a prostatic block. Catheterisation after the procedure is required in 10-40% of cases. Long-term data (5 years) on TUNA demonstrate a sustained improvement of both IPSS score and urinary flow. About a quarter of patients require further intervention at 5 years' follow-up. The safety profile, along with the significant improvement in both objective and subjective parameters observed after TUNA, makes it an attractive approach for symptomatic BPH.

Abstract
We sought to assess the possibility of using pharmacokinetic parameters as a predictor of response to benign prostatic hyperplasia (BPH) pharmacotherapy via a randomized, placebo-controlled, animal preclinical trial using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Twelve male beagles with BPH were enrolled in a preclinical experimental drug trial and divided into two randomized groups with six beagles each: one drug (finasteride) group and one placebo (control) group. Two baseline MRI examinations and three follow-ups during treatment were performed on a clinical 1.5-T MRI system using axial T1- and T2-weighted magnetic resonance images for prostate volume measurement and DCE-MRI for the assessment of prostate microcirculation. A total of 0.2 mmol/kg body weight of the Gd-based contrast agent was administered with an injection rate of 0.2 ml/s. The pharmacokinetic parameters, maximum enhancement ratio (MER), transfer constant and rate constant, were assessed to characterize the microcirculation in the parenchymal zone. The time-signal intensity curve from the external iliac artery was used as the arterial input function. The correlation between baseline evaluations (prostate volume and pharmacokinetic parameters) and therapy-induced prostate volume changes under finasteride treatment were assessed. The changes in prostate volume at the end of the trial exhibited a significant linear correlation to the initial parenchymal MER (P < .02) in the finasteride group. Larger prostate volume reductions coincided with smaller initial parenchymal MER. These findings show considerable promise of using parenchymal MER as a predictor of response to BPH pharmacotherapy with finasteride.

Abstract
Over the last decade, management of benign prostatic hyperplasia (BPH) has changed with a substantial decrease in the use of transurethral prostatectomy (TURP) and a simultaneous increase in the use of medical therapy and minimally invasive surgical therapy (MIST). The goal of management of this chronic progressive condition is not only to provide relief of lower urinary tract symptoms (LUTS) but also to reduce the lifetime risk of adverse outcomes. Recent clinical evidence has demonstrated a clear role for medical therapy, particularly with 5-alpha-reductase inhibitors (5ARIs) either alone or in combination with alpha-blockers, to reduce the risk of acute urinary retention and need for surgery and provide symptom relief. Clinical data on MISTs also indicate a more pronounced short-term effect; however, the long-term durability of these therapies remains uncertain. Minimally invasive surgical therapies confer treatment benefits in a single 1-h treatment session under local anesthesia. Recovery times and adverse events are improved compared with TURP, but issues such as hematuria, prolonged catheterization, urinary tract infection and retreatment remain commonly reported issues. Today, urologists are faced with the challenge of identifying the most appropriate treatment option for the long-term management of BPH. The initial choice for any given patient will depend on his presenting circumstances and the influence of treatment risks on these circumstances. Providing patients with informed treatment decisions is a key element of management.

Abstract
Today, the surgical treatment of the benign prostatic syndrome (BPS) often follows a course of drug treatment. Besides conventional transurethral resection of the prostate (TURP), which has represented the standard therapeutic option for decades, and its in part significant modifications ("vaporizing resection"; bipolar resection), much of the interest has shifted to alternative instrumental procedures like transurethral microwave therapy (TUMT), transurethral needle ablation of the prostate (TUNA) or several laser techniques. By reviewing the current literature, preferably from randomized controlled trials, these different procedures are critically assessed. Moreover, the present role of open prostatectomy is discussed.

Abstract
OBJECTIVE To provide an overview on the current status of the long-term outcomes of instrumental treatment options for patients with lower urinary tract symptoms that are suggestive of bladder outlet obstruction. METHODS Based on MEDLINE database searches, we performed a systematic review of the literature with a focus on peer-reviewed articles about surgical benign prostatic hyperplasia (BPH) therapy published between 2000 and 2005. Special emphasis was given to randomized controlled trials on long-term outcome with a minimum follow-up of five years. RESULTS Data on clinical outcome with a follow-up of more than 10 years are available for open prostatectomy (OP), transurethral resection of the prostate (TURP), and transurethral microwave therapy. Studies with a follow-up of at least five years are obtainable for transurethral incision of the prostate, transurethral vaporisation of the prostate, transurethral needle ablation of the prostate, Holmium:YAG laser enucleation of the prostate, potassium-titanyl-phosphate laser vaporization of the prostate, and interstitial laser coagulation of the prostate. Among these long-term reports, OP and TURP provide the most durable results. CONCLUSIONS The most substantial long-term data on surgical procedures for BPH are available for conventional therapy, namely TURP. Concerning the techniques that have emerged within the last decade, there is clear evidence that the outcomes are more sustainable for truly ablative and thus deobstructing procedures.
