Costs of Managing Benign Prostatic Hyperplasia in the Office and Operating Room

UroLift for Treating Lower Urinary Tract Symptoms of Benign Prostatic Hyperplasia: A NICE Medical Technology Guidance Update

Lower urinary tract symptoms (LUTS) commonly occur as a consequence of benign prostatic hyperplasia (BPH), also known as prostate enlargement. Treatments for this can involve electrosurgical removal of a section of the prostate via transurethral resection of the prostate (TURP), Holmium laser enucleation of the prostate (HoLEP), or prostatic urethral lift using the UroLift system. The UroLift system implants to pull excess prostatic tissue away so that it does not narrow or block the urethra. In this way, the device is designed to relieve symptoms of urinary outflow obstruction without cutting or removing tissue. National guidance recommending the use of UroLift in the UK NHS was first issued in 2015 by the National Institute for Health and Care Excellence (NICE MTG26). We now report on the process to update the economic evaluation of UroLift, leading to updated NICE guidance published in May 2021 (NICE MTG58). The conclusions of the available clinical evidence were mixed and suggested that whilst UroLift improves symptoms over time, this improvement is smaller than that of TURP for symptom severity (IPSS) and urological outcomes. However, UroLift appears to be superior to Rezum for symptom severity and measures of erectile dysfunction and ejaculatory dysfunction. The updated economic model estimated that using UroLift as a day-case procedure for people with prostate of volume 30-80 mL creates a saving of £981 per person compared with bipolar TURP, £1242 compared with monopolar TURP, and £1230 compared with HoLEP.

A Scoping Review of the Economic Burden of Non-Cancerous Genitourinary Conditions

OBJECTIVE

To provide a scoping review of the economic burden of non-cancerous genitourinary conditions (NCGUCs).

METHODS

A scoping review of the literature surrounding the economic costs associated with NCGUCs was conducted for literature published between 1990-2020. The articles were screened and relevant articles were selected for review. These articles were abstracted with information pertaining to the costs surrounding NCGUCs. A descriptive analysis of the data was conducted.

RESULTS

We found 3298 articles in our scoping review. Of these, we found 38 relevant articles related to pelvic floor dysfunction and pelvic organ prolapse, interstitial cystitis, neurogenic bladder, nocturia, urinary tract infections, urolithiasis, urinary incontinence, benign prostatic hyperplasia, overactive bladder, and erectile dysfunction of which the data is reviewed.

CONCLUSION

Although the data in estimating the economic burden is limited, existing evidence demonstrates a significant component of health care spending on NCGUCs. Much of the spending is out-of-pocket and indirect costs that are difficult to measure which may increase the magnitude of the costs. There is a need for future research that takes a holistic look at the economic impact of NCGUCs.

New Endoscopic In-office Surgical Therapies for Benign Prostatic Hyperplasia: A Systematic Review

CONTEXT

In recent years, new technologies have been developed to treat benign prostatic enlargement (BPE). Three of these devices may be utilized in office and are promising additions.

OBJECTIVE

To systematically review all clinical trials investigating prostatic urethral lift (PUL), water vapor thermal therapy (WVTT), and temporary implantable nitinol device (TIND), with emphasis on clinical efficacy and complications.

EVIDENCE ACQUISITION

We performed a systematic review of PubMed/Medline database in November 2020 according to Preferred Reporting Items for Systematic Review and Meta-analysis guidelines.

EVIDENCE SYNTHESIS

Of 168 articles identified, 18 met the inclusion criteria. Evidence consisted of few randomized controlled trials, and multiple single-arm prospective and retrospective studies. Among the three modalities, PUL demonstrates rare occurrence of serious complications but higher retreatment rates at short- and long-term follow-up. WVTT offers lower retreatment rates with a similar safety profile. TIND studies report varying rates of retreatment and complications. All technologies offer low rates of erectile and ejaculatory dysfunction, although the risk appears to be highest for WVTT (<10.8%).

CONCLUSIONS

Among the emerging technologies introduced to treat BPE, the in-office PUL, WVTT, and TIND systems are valuable additions to the current surgical options. These systems offer unique advantages that should be considered in the shared decision-making process.

PATIENT SUMMARY

In this report, we identified all clinical trials reporting on the efficacy and safety of the in-office prostatic urethral lift (PUL), water vapor thermal therapy (WVTT), and temporary implantable nitinol device (TIND) systems for the treatment of benign prostatic enlargement. We found that PUL and WVTT demonstrate acceptable outcomes in terms of functional improvement, retreatment, and complications. More data with longer follow-up are required to further evaluate TIND, but early results are promising.

An Indirect Comparison of Newer Minimally Invasive Treatments for Benign Prostatic Hyperplasia: A Network Meta-Analysis Model

Objective: This study was designed to provide an indirect comparison of the urinary and sexual domain outcomes and complications after newer minimally invasive surgical therapy (MIST) of Aquablation, Rezum, and UroLift for benign prostatic hyperplasia (BPH) for transurethral resection of prostate (TURP). Methods: We searched Embase, Medline, and Cochrane in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, in December 2019. Only randomized clinical trials (RCTs) that reported outcomes after treatment of BPH for prostate less than 80 g with Aquablation, Rezum, or UroLift were included in the analysis. Results: A total of four RCTs reporting the outcomes after treatment with newer MIST for BPH were identified. Patients undergoing the resective procedures, that is, TURP and Aquablation, had greater improvement in urinary domain outcomes: International Prostate Symptom Score, quality of life, peak flow rate, and postvoiding residual compared to patients undergoing nonresective procedures: UroLift and Rezum. Patients in UroLift group maintained a higher sexual function domain score compared to TURP, but not Aquablation. Our multiple comparison analysis did not reveal a significant difference in urinary and sexual domain scores between patients undergoing UroLift and Rezum at 24 months of follow-up. Conclusions: Aquablation and TURP necessitate general or regional anesthesia and both produced significantly better urinary domain scores compared to Rezum and UroLift. On the other hand, UroLift demonstrated better sexual function domain scores compared to TURP, but not Aquablation. There was no significant difference in urinary domain scores between UroLift and Rezum at 24 months of follow-up.

[Cost analysis of GreenLight photoselective vaporization of the prostate versus standard transurethral resection of the prostate: Benefit of ambulatory care]

PURPOSE

To compare the costs associated with GreenLight XPS 180W photoselective vaporization of the prostate (PVP) for an outpatient versus standard transurethral resection of the prostate (TURP) with a three nights hospitalization in a French private hospital.

MATERIAL AND METHODS

A retrospective cost minimization analysis was performed between 2017 and 2019 in a French private hospital for the hospital stays associated with TURP and PVP procedures for benign prostatic hyperplasia (BPH). The peri-operative cost-benefit assessment of the two procedures was analyzed from the establishment's point of view according to the micro-costing method.

RESULTS

871 surgical treatment for BPH had been performed during the period of the study, including 743 photoselective laser vaporization (85%). The average length of stay of patients undergoing TURP was 3,7 days versus 0,9 days for PVP including 64,7% ambulatory. The cost-benefit was more of 500€ per patient in favor of ambulatory PVP compared with TURP in conventional three nights hospitalization for level 1 hospital stays.

CONCLUSION

In this private hospital center, ambulatory PVP seemed more cost-effective than TURP with a three nights hospitalization for a severity level 1 patient. The financial profit for the establishment was mostly due to reduction of the main length of stay and ambulatory care.

Tight junction protein claudin-1 is downregulated by TGF-β1 via MEK signaling in benign prostatic epithelial cells

BACKGROUND

Benign prostatic hyperplasia (BPH) is arguably the most common disease in aging men. Although the etiology is not well understood, chronic prostatic inflammation is thought to play an important role in BPH initiation and progression. Our recent studies suggest that the prostatic epithelial barrier is compromised in glandular BPH tissues. The proinflammatory cytokine transforming growth factor beta 1 (TGF-β1) impacts tight junction formation, enhances epithelial barrier permeability, and suppresses claudin-1 messenger RNA expression in prostatic epithelial cells. However, the role of claudin-1 in the prostatic epithelial barrier and its regulation by TGF-β1 in prostatic epithelial cells are not clear.

METHODS

The expression of claudin-1 was analyzed in 22 clinical BPH specimens by immunohistochemistry. Human benign prostate epithelial cell lines BPH-1 and BHPrE1 were treated with TGF-β1 and transfected with small interfering RNAs specific to claudin-1. Epithelial monolayer permeability changes in the treated cells were measured using trans-epithelial electrical resistance (TEER). The expression of claudin-1, E-cadherin, N-cadherin, snail, slug, and activation of mitogen-activated proteins kinases (MAPKs) and AKT was assessed following TGF-β1 treatment using Western blot analysis.

RESULTS

Claudin-1 expression was decreased in glandular BPH tissue compared with adjacent normal prostatic tissue in patient specimens. TGF-β1 treatment or claudin-1 knockdown in prostatic epithelial cell lines increased monolayer permeability. TGF-β1 decreased levels of claudin-1 and increased levels of snail and slug as well as increased phosphorylation of the MAPK extracellular signal-regulated kinase-1/2 (ERK-1/2) in both BPH-1 and BHPrE1 cells. Overexpression of snail or slug had no effect on claudin-1 expression. In contrast, PD98059 and U0126, inhibitors of the upstream activator of ERK-1/2 (ie, MEK-1/2) restored claudin-1 expression level as well as the epithelial barrier.

CONCLUSION

Our findings suggest that downregulation of claudin-1 by TGF-β1 acting through the noncanonical MEK-1/2/ERK-1/2 pathway triggers increased prostatic epithelial monolayer permeability in vitro. These findings also suggest that elevated TGF-β1 may contribute to claudin-1 downregulation and compromised epithelial barrier in clinical BPH specimens.

Comparative Effectiveness of Transurethral Prostate Procedures at Enabling Urologic Medication Discontinuation: A Retrospective Analysis

OBJECTIVE

To test the hypothesis that transurethral prostate procedures (TUPPs) eliminating tissue result in greater medication discontinuation and lower de novo initiation rates than procedures inducing tissue necrosis.

METHODS

Retrospective review of all men undergoing first time TUPPs at a large tertiary center from 2001 to 2016 was completed. Procedure type and urologic medication use before, 3-12 months after, and greater than 12 months after TUPP were analyzed with simple open prostatectomy as a comparator. Tissue-eliminating TUPPs included transurethral resection of the prostate and laser prostatectomy. Tissue-necrosing procedures included microwave therapy (transurethral microwave therapy) and radiofrequency ablation (transurethral needle ablation), which were grouped in analyses. Medication types were 5-alpha reductase inhibitors (5ARI), alpha blockers, anticholinergics, and beta-3 agonists (B3A).

RESULTS

A total 5150 TUPPs were analyzed. Preoperative medication use significantly varied across TUPPs for 5ARI (P <.01), alpha-blockers (P .01), and anticholinergics (P .047), but not B3A (P .476). Transurethral resection of the prostate and laser prostatectomy were associated with significantly higher medication discontinuation rates and lower resumption and initiation rates compared to tissue-necrosing procedures. Relative to TUPPs, simple prostatectomy had significantly higher medication discontinuation, as well as the lowest resumption and initiation rates.

CONCLUSION

Tissue-eliminating benign prostatic hyperplasia procedures were associated with better medication discontinuation, resumption, and de novo initiation rates compared to tissue-necrosing benign prostatic hyperplasia procedures.

Office-based vs. operating room-performed laryngopharyngeal surgery: a review of cost differences

Purpose

Office-based transnasal flexible endoscopic surgery under topical anesthesia has recently been developed as an alternative for transoral laryngopharyngeal surgery under general anesthesia. The aim of this study was to evaluate differences in health care costs between the two surgical settings.

Methods

PubMed, EMBASE and Cochrane Library were searched for studies reporting on costs of laryngopharyngeal procedures that could either be performed in the office or operating room (i.e., laser surgery, biopsies, vocal fold injection, or hypopharyngeal or esophageal dilation). Quality assessment of the included references was performed.

Results

Of 2953 identified studies, 13 were included. Quality assessment revealed that methodology differed significantly among the included studies. All studies reported lower costs for procedures performed in the office compared to those performed in the operating room. The variation within reported hospital and physician charges was substantial.

Conclusion

Office-based laryngopharyngeal procedures under topical anesthesia result in lower costs compared to similar procedures performed under general anesthesia.

Cost Comparison of Benign Prostatic Hyperplasia Treatment Options

PURPOSE OF REVIEW

To provide an economic context within which to consider treatment options for benign prostatic hyperplasia (BPH). To this end, this review provides a comparison of the costs of combination medical therapy, operative treatment, and office-based therapies for BPH from a payer perspective.

RECENT FINDINGS

Analysis of Medicare charges from the authors' institution, as well as local retail costs of medication, demonstrated a wide range in costs of commonly used BPH treatments. In this study, interventions for BPH reached cost equivalence with combination medical therapy within 6 months to 8 years. A myriad of options for managing men with symptomatic BPH exist. It is prudent not only to consider surgeon preference and patient-specific factors when selecting a treatment but also to understand the economic impact different BPH therapies confer.

Rezūm Water Vapor Thermal Therapy for Lower Urinary Tract Symptoms Associated With Benign Prostatic Hyperplasia: 4-Year Results From Randomized Controlled Study

OBJECTIVE

To report 4-year outcomes of the randomized controlled trial of water vapor thermal therapy for treatment of moderate to severe lower urinary tract symptoms due to benign prostatic hyperplasia.

MATERIALS AND METHODS

Total 188 subjects; 135 men ≥50years old, International Prostate Symptom Score ≥ 13, maximum flow rate (Qmax) ≤15 mL/s and prostate volume 30 to 80 cc treated with Rezūm System thermal therapy were followed 4 years; subset of 53 men who requalified for crossover from control to active treatment were followed 3years.

RESULTS

Lower urinary tract symptoms were significantly improved within ≤3 months after thermal therapy and remained consistently durable (International Prostate Symptom Score 47%, quality of life 43%, Qmax 50%, Benign Prostatic Hyperplasia Impact Index 52%) throughout 4years (P <.0001); outcomes were similarly sustained in crossover subjects at 3years. Surgical retreatment rate was 4.4% over 4years. No disturbances in sexual function were reported.

CONCLUSION

The minimally invasive thermal therapy provides effective symptom relief and improved quality of life that remains durable for over 4years. It is applicable to all prostate zones with procedures performed under local anesthesia in an office setting.
