comparative cost effectiveness of surgery collagenase clostridium histolyticum and penile Traction Therapy in men with peyronie s disease in an era of effective clinical treatment
The Journal of Sexual Medicine, 2019Co-Authors: K Wymer, Tobias S Kohler, Landon TrostAbstract:Abstract Background Traditionally, surgery has been considered the gold standard treatment for Peyronie’s disease (PD). Less-invasive alternatives, such as collagenase Clostridium histolyticum (CCH) and Traction Therapy, have been proposed and proven effective. Aim To compare cost-effectiveness of management options for PD. Methods A Markov analytic model was created to compare the cost-effectiveness of treatment with a novel Traction device, RestoreX (RXPTT), vs CCH vs surgery. Outcomes were derived from single-institution, prospective data of 63 men treated with RXPTT, 115 with CCH, and 23 with plication or incision and grafting. Costs were based on 2017 Medicare reimbursement and utility values from the literature. Main Outcome Measures Model outcomes included complications for each treatment arm, as well as the probability of success, which was defined as ≥20% improvement in curvature. Univariable and multivariable sensitivity analyses were performed to test the robustness of the model. Results Overall success rates were 96% (surgery), 66% (CCH), and 48% (RXPTT). At 10 years after treatment, RXPTT was the most cost-effective, with mean costs per patient of $883 (RXPTT), $11,419 (surgery), and $33,628 (CCH). CCH and surgery both resulted in a gain of quality adjusted life years (QALYs) relative to RXPTT (9.44 and 9.36 vs 9.27, respectively). Sensitivity analysis demonstrated greater cost-effectiveness for surgery if lower (≤46%) rates of postoperative erectile dysfunction or length loss (≤3%). CCH became more cost-effective at lower costs (≤$16,726) or higher success rates (≥76%). On multivariable sensitivity analysis at a willingness to pay threshold of $100,000/QALY, the most cost-effective strategy was RXPTT in 49%, surgery in 48%, and CCH in 3% of simulations. At a willingness to treat threshold of $150,000/QALY, the most cost-effective treatment option was RXPTT in 33%, surgery in 55%, and CCH in 12% of simulations. Clinical Implications In an era of value-based care, this model can guide cost-effective treatment selection on the basis of provider, patient, and payer characteristics. Strengths & Limitations The current study represents the first cost-effectiveness comparison of treatment modalities for PD and is strengthened by prospective data collection, large CCH and Traction sample sizes, and robust sensitivity analyses. Consistent with cost-effective models, the model is limited by assumptions and may not apply to all scenarios. Conclusions RXPTT represents a more cost-effective method for achieving ≥20% curvature improvement compared with surgery or CCH. Depending on treatment goals, rate of surgical complications, and willingness to pay threshold, surgery and CCH may become more cost-effective in select scenarios. Wymer K, Kohler T, Trost L.

efficacy of combined collagenase clostridium histolyticum and restorex penile Traction Therapy in men with peyronie s disease
The Journal of Sexual Medicine, 2019Co-Authors: Manaf Alom, Tobias S Kohler, Kiran Lata Sharma, Amir Toussi, Landon TrostAbstract:Abstract Background Previous studies of penile Traction Therapy (PTT) devices have demonstrated limited/no efficacy when combined with intralesional therapies for Peyronie’s disease (PD). Recently, randomized data have demonstrated the efficacy of a novel PTT device, RestoreX, developed in cooperation with the Mayo Clinic, in men with PD. Aim To assess the safety and efficacy of treatment with the RestoreX device plus collagenase Clostridium histolyticum (CCH) compared with CCH alone and CCH with other PTT devices. Methods A prospective registry has been maintained of all men undergoing CCH injections for PD between March 2014 and January 2019. Assessments were performed at baseline, during each series, and after completion of treatment. Those completing Therapy (8 injections or sooner if satisfied) were categorized into group 1 (CCH alone), group 2 (CCH plus any PTT device other than RestoreX), or group 3 (CCH plus RestoreX). Outcomes Changes in penile length, curvature, and subjective perception and the occurrence of adverse events. Results Of 287 men with data on PTT use, 113 had completed Therapy with all objective data available and compose the current cohort. Baseline demographic and pathophysiological variables were similar among the 3 groups except penile length and previous PD medications. Following treatment, group 3 demonstrated significantly greater improvements in curvature (mean, 20.3°/31% for group 1, 19.2°/30% for group 2, and 33.8°/49% for group 3), length (-0.7 cm/-4%, -0.4 cm/-2%, and +1.9 cm/+17%, respectively), and subjectively estimated curvature improvement (44%, 32%, and 63% respectively), despite shorter daily PTT use (0.9 vs 1.9 hours/day). Group 3 was more likely than the other groups to experience ≥20°, ≥20%, and ≥50% curvature improvements, ≥1 cm length gain, and ≥20% length improvement. All results were statistically significant for group 3 versus groups 1 and 2, but not between groups 1 and 2, even after controlling for baseline features and isolating a subset of ≥3 hours/day PTT use (group 2). Group 3 was 6.9 times more likely to achieve ≥20° curvature improvement, and 3.5 times more likely to achieve ≥50% curvature improvement, and 10.7 times more likely to experience ≥20% length improvement. Adverse events were similar among the 3 groups. Clinical Implications Use of the RestoreX device enhances mean curvature outcomes by 71% and increases penile length in men with PD receiving CCH Therapy. Strengths & Limitations Study strengths include a prospective registry, consistent assessments, the largest single-site series with complete posttreatment outcomes reported to date, the largest PTT series reported to date, and a true-to-life clinical design. Limitations include the nonrandomized methodology and single-site setting. Conclusion The combination of RestoreX and CCH is associated with significantly greater curvature and length improvements compared with CCH alone or CCH with other PTT devices.

Experiment and Dynamic Simulation of Cervical Tractions in Inclined and Sitting Positions
2017Co-Authors: Lawrence K. F. Wong, Nobuyuki Kurusu, Keiji FujinoAbstract:This study aims to validate the accuracy of a cervical Traction Therapy simulation model by comparing the intervertebral separations of six asymptomatic male adults when Traction was applied to their cervical spines. The subjects were tested on two mechanical Traction devices, representing the inclined and sitting positions. A total of 55 radiographic images of their cervical spines were taken before and during Traction. The result showed statistically significant intervertebral space changes in the inclined position but the changes in the sitting position were not statistically significant. The observed changes of the cervical spine were used to adjust parameters of the Traction Therapy model, which contains a human model with cervical spine built with springs and dampers and two Traction devices in inclined and sitting positions. A series of Traction forces and Traction angles were applied to the model to simulate the actual parameters used in the experiment and the new model was used to evaluate the two Traction positions. The result suggested that inclined position creates greater intervertebral separations on the posterior sides. Differences in separations due to age were not observed in both positions. The result also suggested that the inclined position provides better control in positioning the separations at different spinal segments than the sitting position.

thu0493 a multicentre randomised controlled follow up study of effects of the underwater Traction Therapy in chronic low back pain
Annals of the Rheumatic Diseases, 2019Co-Authors: Tamas Gati, Eva Czimer, Gyorgyi Cserhati, Judit Feher, Mihaly Olah, Agota Kulisch, Zsuzsanna Mando, Tamas BenderAbstract:Background: Chronic low back pain established for more than 3 months is one of the most common problems in the world. The prevalence could reach the 33%. Objectives: To investigate the effects of underwater Traction Therapy on chronic low back pain. The primary objective was to prove the hypothesis that underwater Traction Therapy has favourable effect of LBP using the change in the clinical parameters. Our secondary objective was to evaluate whether it also leads to the improvement in the quality of life. Methods: A prospective, multicenter, comparative (intervention arm vs. control arm), randomized follow-up study. Participants aged between 18 and 85 years with more than 3 months low back pain and selected from outpatient clinics. The participants were randomized to three groups: underwater weight bath Traction Therapy, weight bath and non-steroidal anti-inflammatory drugs (NSAIDs) medication and only non-steroidal anti-inflammatory drugs (NSAIDs) medication. During the Traction Therapy ankle weights were used. The following parameters were measured before, right after, and nine weeks after the three-week Therapy: level of low back pain in rest, level during activity tested using the Visual Analog Scale (VAS); specific questionnaire on back pain (Oswerty); questionnaire on quality of life (EuroQual-5D) and clinical parameters. Results: 141 participants aged 57.67 (±13.04) years. All of the investigated parameters improved significantly (p Conclusion: Based on our results, underwater weight bath Traction Therapy, might have favourable impact on the clinical parameters and quality of life of patients suffering from chronic low back pain.

The effects of weightbath Traction hydroTherapy as a component of complex physical Therapy in disorders of the cervical and lumbar spine: a controlled pilot study with follow-up
Rheumatology International, 2008Co-Authors: Mihaly Olah, Judit Feher, Levente Molnár, József Dobai, Csaba Oláh, Tamas BenderAbstract:The therapeutic modalities available for the conservative management of chronic cervical and lumbar pain include underwater Traction, the usefulness of which is not universally acknowledged. No reports have been published on clinical trials evaluating underwater Traction. This study was intended to ascertain any beneficial impact of weightbath Therapy on the clinical parameters and quality of life of patients with cervical/lumbar discopathy. The study population comprised 72 subjects. Two groups of 18 patients each received underwater Traction Therapy of the cervical or lumbar spine with add-on McKenzie exercises and iontophoresis. The remaining two groups, treated with exercises and iontophoresis, served as controls. VAS and SF36 scores, range of motion were monitored to appraise therapeutic efficacy in cervical discopathy, whereas these parameters were supplemented by the Oswestry index in lumbar discopathy. A MRI scan was done at baseline and after 3 months of follow-up. Underwater cervical or lumbar Traction Therapy for discopathy achieved significant improvement of all study parameters, which was still evident 3 months later. Among the controls, significant improvement of just a single parameter was seen in patients with lumbar, and of two parameters in those with cervical discopathy. Underwater Traction Therapy effectively mitigates pain, enhances joint flexibility, and improves the quality of life of patients with cervical or lumbar discopathy. The equipment required to administer weightbath Therapy is simple to install and treatment technique is straightforward.
