Putting Patients Ahead by Leaving Nothing Behind: An Emerging Treatment Paradigm in Minimally Invasive Surgical Therapy for Benign Prostatic Hyperplasia

Which improvements does Rezum bring to BPH management? A network meta-analysis and comparison of water vapor therapy and conduction ablation techniques

INTRODUCTION

This study evaluated the effectiveness and safety of Rezum water vapor thermal therapy (Rezum) and compared them with those of traditional conduction ablation methods for the management of benign prostatic hyperplasia.

EVIDENCE ACQUISITION

A comprehensive review of studies from the PubMed, Cochrane, and EMBASE databases was performed. Only randomized clinical trials that reported the outcomes of thermal ablation treatments, including transurethral microwave therapy (TUMT), transurethral needle ablation (TUNA), and Rezum, were included. A network meta-analysis was performed to compare these treatments.

EVIDENCE SYNTHESIS

Sixteen studies comprising 1622 patients were included. Rezum did not show efficacy superior to that of traditional conduction ablation methods in terms of the International Prostate Symptom Score, quality of life, peak urinary flow rate, and postvoid residual volume. The incidence of acute urinary retention associated with Rezum was similar to that associated with other conduction ablation methods of TUMT and TUNA and transurethral resection of the prostate. Regarding ejaculatory dysfunction, Rezum resulted in outcomes comparable to those of sham treatment. According to the surface under the cumulative ranking curve, Rezum resulted in the lowest incidence of ejaculatory dysfunction.

CONCLUSIONS

Rezum provides functional outcomes of urinary symptoms that are comparable to those of conduction ablation therapies. Notably, among the minimally invasive thermal ablation therapies evaluated during this study, Rezum resulted in the lowest incidence of ejaculatory dysfunction.

Evaluating the Impact of Benign Prostatic Hyperplasia Surgical Treatments on Sexual Health

Benign prostatic hyperplasia (BPH), a prevalent condition in older men, is often managed through various surgical interventions. This narrative review aims to explore the impact of these surgical treatments on sexual function, a critical aspect of patient quality of life often overlooked in BPH management. The methodology encompassed a thorough review of contemporary surgical techniques for BPH, including prostate resection, enucleation, vaporization, and minimally invasive therapies such as UroLift, Rezum, and Aquablation. Additionally, the focus was on patient-centered outcomes, with a special emphasis on sexual health following surgery. Findings reveal that, while surgical interventions effectively alleviate BPH symptoms, they often have significant repercussions in sexual function, including erectile and ejaculatory dysfunction. However, emerging techniques demonstrate potential in preserving sexual function, underscoring the need for patient-centric treatment approaches. The study highlights the complex interplay between BPH surgery and sexual health, with minimally invasive treatments showing promise in balancing symptom relief and sexual function preservation. In conclusion, the study advocates for an integrated, interdisciplinary approach to BPH treatment, emphasizing the importance of considering sexual health in therapeutic decision-making. This narrative review suggests a paradigm shift towards minimally invasive techniques could optimize patient outcomes, marrying symptom relief with quality-of-life considerations. The need for further research in this domain is evident, particularly in understanding long-term sexual health outcomes following different surgical interventions for BPH.

Cost-effectiveness analysis of minimally invasive surgical treatments for benign prostatic hyperplasia: implications for Japan's public healthcare system

AIMS

Benign prostatic hyperplasia (BPH) represents a significant public health issue in Japan. This study evaluated the lifetime cost-effectiveness of water vapor energy therapy (WAVE) versus prostatic urethral lift (PUL) for men with moderate-to-severe BPH from a public healthcare payer's perspective in Japan.

MATERIALS AND METHODS

A decision analytic model compared WAVE to PUL among males in Japan. Clinical effectiveness and adverse event (AE) inputs were obtained from a systematic literature review. Resource utilization and cost inputs were derived from the Medical Data Vision database and medical service fee national data in Japan. Experts reviewed and validated model input parameters. One-way and probabilistic sensitivity analyses were conducted to determine how changes in the values of uncertain parameters affect the model results.

RESULTS

Throughout patients' lifetimes, WAVE was associated with higher quality-adjusted life years (0.920 vs. 0.911 year 1; 15.564 vs. 15.388 lifetime) and lower total costs (¥734,134 vs. ¥888,110 year 1; ¥961,595 vs. ¥1,429,458 lifetime) compared to PUL, indicating that WAVE is a more effective and less costly (i.e. dominant) treatment strategy across all time horizons. Lifetime cost-savings for the Japanese healthcare system per patient treated with WAVE instead of PUL were ¥467,863. The 32.7% cost difference between WAVE and PUL was predominantly driven by lower WAVE surgical retreatment rates (4.9% vs. 19.2% for WAVE vs PUL, respectively, at 5 years) and AE rates (hematuria 11.8% vs. 25.7%, dysuria 16.9% vs. 34.3%, pelvic pain 2.9% vs. 17.9%, and urinary incontinence 0.4% vs. 1.3% for WAVE vs PUL, respectively, at 3 months). Model findings were robust to changes in parameter input values.

LIMITATIONS

The model represents a simplification of complex factors involved in resource allocation decision-making.

CONCLUSIONS

Driven by lower retreatment and AE rates, WAVE was a cost-effective and cost-saving treatment for moderate-to-severe BPH in Japan compared to PUL, providing better outcomes at lower costs to the healthcare system.

Long-Term Risk of Surgery Following First Diagnosis of Benign Prostatic Hyperplasia in Middle-Aged Men

Objective

Pharmacotherapy is often used to relieve lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH), yet surgery may be indicated for persistent bothersome symptoms. BPH is common among older men, yet the burden of BPH among middle-aged men may be under-recognized. This study examined the 5-year risk of BPH surgery among middle-aged men following the first BPH diagnosis.

Methods

Using the IBM MarketScan Commercial Claims and Encounters Database, males aged 35 to 64 years with a first-time primary diagnosis of BPH who were prescribed oral medication for LUTS were identified. The primary outcome was the risk of BPH surgery within five years of the first BPH diagnosis, which was analyzed using Kaplan-Meier methods. The influence of patient demographics, comorbidities, and medication use on the risk of BPH surgery was explored using a Cox proportional hazards model. 

Results

Four thousand five hundred ten eligible men, 460 underwent BPH surgery within five years of BPH diagnosis. The most common surgical procedures were transurethral resection of the prostate and laser enucleation. The risk of BPH surgery over five years following BPH diagnosis was 10.2% (95% CI: 9.4% to 11.1%). In a multivariable Cox proportional hazards regression analysis, patient age was the primary factor associated with higher surgery risk. Compared to men aged 35 to 44 years, the hazard ratio for BPH surgery was 3.9 (95% CI: 1.9 to 8.4; p<0.001) among men aged 45 to 54 years, and 5.0 (95% CI: 2.4 to 10.6; p<0.001) among men aged 55 to 64 years.

Conclusions

In middle-aged men prescribed oral medication for LUTS secondary to BPH, the risk of BPH surgery was 10.2% over five years. This risk may be underappreciated and highlights the clinical need for surgical procedures with favorable risk-to-benefit profiles.

Preserving ejaculatory function in young patients with lower urinary tract symptoms: medium- to long-term follow-up of prostatic urethral lift at a single center

BACKGROUND AND AIMS

Prostatic urethral lift (Urolift™) is a minimally invasive technique to treat male lower urinary tract symptoms (LUTSs) due to benign prostatic hyperplasia (BPH). The aim of the present study was to assess safety and medium- to long-term outcomes in the relief of urinary symptoms.

METHODS

We included 35 men, affected by severe symptomatic BPH evaluated by International Prostate Symptom Score (IPSS), with normal erectile function (EF) and ejaculatory function (EjF) evaluated by the International Index of Erectile Dysfunction (IIEF-5) and Male Sexual Health Questionnaire for Ejaculatory Dysfunction (MSHQ-EjD-SF). Exclusion criteria were prostate larger than 70 cm3, bladder neck sclerosis, concomitant third prostatic lobe, and/or other cervical urethral obstruction or cancer. All patients, preoperatively, performed uroflowmetry (UFM) with peak flow (Q-max) and post void residual volume (PVR), digital rectal exam, transrectal prostate ultrasound to measure prostate volume, PSA, and cystoscopy. Follow-up was scheduled at 1-3-6 months, then yearly, evaluating UFM, IPSS, IIEF-5, and MSHQ-EjD-SF.

RESULTS

All procedures were performed by a single senior surgeon and follow-up was 33.8 ± 12 months. Preoperative PSA was 0.82 ± 0.4 ng/ml and mean operative time was 19.6 ± 10 min and 3 (2-4) implants per patient were used. Parameters reported at last follow-up schedule were: Q-max increase of 68% (p = 0.001), PVR reduction 68% (p = 0.005), and IPSS reduction 55% (p < 0.0001). EF and EjF were similarly preserved, and no patients presented retrograde ejaculation. A total of 88.6% of patients were satisfied with LUTSs improvement and 100% satisfied with EjF.

CONCLUSION

Urolift can improve urinary disorders secondary to BPH, preserving EjF and EF. It is a safe and easy method, reproducible, and with low incidence of complications. Careful selection of patients is mandatory. The main reason for dissatisfaction is the higher expectation of better BPH symptoms relief although patients with high bladder neck and/or prostate volume >45 cm3 were aware of the possible failure.
