Insurance approval rates for collagenase clostridium histolyticum prior to discontinuation: a Canada-wide analysis. Int J Impot Res 2024; 36:581-587. [PMID: 37626201 DOI: 10.1038/s41443-023-00749-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 07/24/2023] [Accepted: 07/25/2023] [Indexed: 08/27/2023]
Abstract
Collagenase Clostridium histolyticum (CCh), the first approved non-surgical treatment for Peyronie's disease (PD), was withdrawn from the European, Canadian, and Asian markets due to poor demand and lack of government reimbursement options. We sought to assess insurance approval rates and usage of CCh across Canada to understand the factors that led to its withdrawal. Data on patients prescribed CCh for PD or Dupuytren's contracture was obtained through collaboration with BioScript Solutions to assess the association of variables with insurance approval and prescription filling. We identified 3297 insurance coverage applications for Xiaflex® from April 2018 to June 2020. Of all applications for PD, 92.9% applications were approved while 7.1% were rejected. Despite the withdrawal of CCh from Canadian markets, coverage application approval rates for 2018, 2019, and 2020 were 86.5%, 90.1%, and 89.1%, respectively. Of 2921 approved applications, 88.8% prescriptions were filled. For the 376 rejected applications, 66.4% of prescriptions were filled. Overall, 90% of the cost of Xiaflex® was covered in Canada among those with extended health benefits, with an out-of-pocket expense of $210.4. Insurance coverage requests for Xiaflex® were approved at a high rate in Canada with approved patients being very likely to proceed with therapy, despite interprovincial variation.

Chronological perspective of substitute materials used for the surgical treatment of Peyronie’s disease: A scoping review of literature. Urologia 2022:3915603221137947.

Abstract
This comprehensive scoping review aimed to identify all up-to-date original publications relating to substitute materials used for the surgical treatment of Peyronie’s disease (PD), and characterize what material in which chronological trends were published in the current literature. Using the PCC framework (P: population, C: concept, and C: context), a search strategy was developed and used in four electronic databases, in addition to the Google scholar. All current published, in-press, and pre-print manuscripts with available English full-text were included. Eligible studies were required to be original research articles of any study design, reporting the usage of grafts on surgical treatment of PD. Included studies were reported in a narrative synthesis format. A total of 3379 articles were identified via an electronic search of databases and a total of 171 articles entered this scoping review. Most studies originated from Europe ( n = 72) and North America ( n = 66). Reports from the other continents increase in number in the 21st century. Highest number of the published papers was seen in 2001 to 2005 pentad. Autologous grafts (53.5%). Allografts (22.7%) and xenografts (15.7%) were the most frequently reported materials. Time flow of the used material and the alterations in trends for them is quite considerable. A global perspective of relevant publications on substitute materials in the surgical management of PD is presented in this review. The information in this summary may assist in establishing future research priorities in this area.

Int J Impot Res 2021; 34:786-789. [PMID: 34743194 DOI: 10.1038/s41443-021-00486-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 10/10/2021] [Accepted: 10/15/2021] [Indexed: 11/09/2022]
Abstract
Characterization of Peyronie's disease (PD) involves manual goniometry and penile length measurement. These techniques neglect volume loss or hourglass deformities. Inter-provider variability complicates accuracy. Using 3D-printed models, we aimed to evaluate measurement accuracy and variability and establish computational assessment workflows. Five digital phantoms were created: 13.0 cm cylinder, 13.0 cm hourglass cylinder, 15.0 cm cylinder with 40° angulation, 12.0 cm straight penis, and 12.9 cm PD penis with 68° angulation and hourglass. Lengths, volumes, and angles were determined computationally. Each phantom was 3D-printed. Ten urology providers determined lengths, angles, and volumes with measuring tape, goniometer, and volume calculator. Provider versus computational measurements were compared to determine accuracy using t-tests or Wilcoxon rank-sum tests. No significant differences were observed between manual assessment of length of penile models and designed length in penile models. Average curvature angles from providers for bent cylinder and PD phantoms were 38.3° ± 3.9° (p = 0.25) and 57.5° ± 7.2° (p = 0.006), respectively. When assessing for volume, hourglass cylinder and bent cylinder showed significant differences between designed volume and provider averages. All assessments of length, angle, and volume showed significant provider variability. Our results suggest manual measurements suffer from inaccuracy and variability. Computational workflows are useful for improved accuracy and volume assessment.

The Virtual 3-Dimensional Reconstruction of Penile Curvature in Patients With Peyronie's Disease: A Pilot Study. J Sex Med 2020; 18:209-214. [PMID: 33191184 DOI: 10.1016/j.jsxm.2020.09.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Revised: 09/21/2020] [Accepted: 09/28/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Peyronie's disease is an idiopathic fibrotic disease affecting the penile tunica albuginea. Among other resulting deformities, the more common penile curvature should be assessed preferentially with in-office goniometric estimation after pharmacologically induced erection, although clearly invasive and uncomfortable. AIM In the present pilot study, we investigated the usefulness for the patient and the surgeon of a 3-dimensional (3D) reconstruction of the penile curvature obtained through photogrammetry software in clinical evaluation and surgical planning. METHODS Enrolled patients received alprostadil 10 μg by intracavernous injection. Then, the medical personnel took a sequence of up to 50 photographs in orthostatism via a smartphone and processed them to obtain a 3D model of the whole groin area with 3DF Zephyr free software (3Dflow SRL, Verona, Italy), to take measurements of the penile curvature with MeshLab software (National Research Council of Italy, Rome, Italy) and to simulate the results after corporoplasty with Blender software (Blender Foundation, Amsterdam, the Netherlands). Finally, we submitted a 1-5 Likert scale to patients and surgeons investigating their satisfaction with the use of the 3D model during preoperative counseling, surgical planning, and the esthetic results after surgery. OUTCOMES We investigated the patient and surgeon satisfaction with the use of the 3D model in understanding/evaluating the pathology and the surgical planning during the preoperative visit and the satisfaction with the final esthetic results in relation to the preoperative model itself. RESULTS 4 patients were included. The median photographs acquisition and computer processing time were 39 seconds and 347.5 minutes, respectively. All the patients and surgeons involved gave a score of ≥4 to all the items investigated. CLINICAL IMPLICATIONS The 3D model of the penile curvature is very useful both to the patient and the surgeon to understand the severity of the disease and the possible surgical management. STRENGTH & LIMITATIONS This is a pilot study including only 4 cases, but it is the first experience in which the patients with Peyronie's disease had the possibility to see a virtual 3D model of their penile curvature and final esthetic results after corporoplasty, based on 3 freely available computer applications. CONCLUSION Our pilot study has shown that it is possible to quickly obtain a sequence of photographs to create an accurate virtual 3D model of the penis of patients with Peyronie's disease, helping the patients and the surgeon during preoperative counseling and surgical planning.
