Abstract
OBJECTIVE To evaluate risk factors leading to corporal rupture after Collagenase Clostridium histolyticum (CCh). Peyronie's disease (PD) is a fibrotic condition of the penis characterized by abnormal plaque formation. Intralesional CCh is the only FDA-approved medication for PD, however, it can lead to corporal rupture, a potential surgical emergency. METHODS We retrospectively reviewed medical records from Veterans diagnosed with PD who were under treatment with CCh using the Veterans Administration Informatics and Computing Infrastructure (VINCI). Using International Classification of Diseases and Current Procedural Terminology codes, we identified men who suffered a corporal rupture after CCh. Individual charts were reviewed to determine potential risk factors and events leading to corporal rupture. RESULTS We identified 17,647 veterans who were diagnosed with PD, of which 8.7% (1541) received at least one injection of CCh for PD. Of them, 0.7% (11/1541) veterans suffered corporal rupture. Within these 11 patients, the median number of CCH injections was 6 with a median initial curvature of 35°. Fracture occurred at a median of 8days after CCH injection. The majority of fractures were secondary to spontaneous erections or sexual intercourse. Finally, six patients had their fracture repaired surgically while the remaining were managed conservatively. CONCLUSION Most fractures occurred within 2weeks of CCh injections and were associated with sexual intercourse and spontaneous morning erections.

Hardesty J, Burns RT, Soyster ME, Mellon M, Bernie HL. A review of the literature and proposed algorithm for penile fracture management. Sex Med Rev 2023; 12:100-105.

Abstract
INTRODUCTION In the management of penile fractures, immediate surgical repair has resulted in better outcomes when compared with a conservative approach; however, there is currently no consensus on the treatment of patients presenting beyond the immediate period (>24 hours) following injury. OBJECTIVES To examine the latest literature on management strategies in penile fracture and propose an optimal algorithm for the treatment of patients with delayed presentation. METHODS A comprehensive search was conducted following the PRISMA-P 2020 guidelines. A search was performed in several databases with the following strategy: ("Penile fracture" OR "fracture of penis" OR "rupture of corpora cavernosa" OR "rupture of tunica albuginea") AND (management OR treatment OR surgery OR "surgical reconstruction" OR "surgical repair"). This resulted in 108 relevant articles. Two independent reviewers screened these articles according to the inclusion criteria. Full-text review of 56 articles was performed, and ultimately 20 studies were selected. Measures included the use of diagnostic imaging, timing of surgical repair (immediate, <24 hours after injury; delayed, >24 hours), surgical approach, and long-term complications (ie, erectile dysfunction and penile curvature). RESULTS The review highlighted the benefits of immediate surgical repair in penile fractures, demonstrating improved patient outcomes. Furthermore, it found that surgical repair should be considered even in cases with delayed presentation (>24 hours after injury). To better evaluate the long-term impact of delayed surgical intervention on patient outcomes, we recommend standardized postoperative follow-up, with routine assessments of erectile function and penile curvature. CONCLUSION Contemporary literature suggests that immediate and delayed surgical repair of penile fractures leads to adequate postoperative outcomes, and patients presenting >24 hours after injury should still be considered for surgery.

Incremental Treatment Response by Cycle With Collagenase Clostridium Histolyticum for Peyronie's Disease: A Pooled Analysis of Two Phase 3 Trials. Urology 2023; 175:126-131. [PMID: 36863600 DOI: 10.1016/j.urology.2023.02.019] [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: 11/23/2022] [Revised: 01/26/2023] [Accepted: 02/08/2023] [Indexed: 03/04/2023]
Abstract
OBJECTIVE To evaluate cumulative and incremental changes in penile curvature after each treatment cycle of collagenase clostridium histolyticum (CCH) in men with Peyronie's disease (PD). METHODS Data from 2 phase 3, randomized, placebo-controlled trials were analyzed post hoc. Treatment was administered in up to 4 treatment cycles (per cycle: 2 injections, 1-3 days apart, of CCH 0.58 mg or placebo; subsequent penile modeling) at 6-week intervals. Penile curvature was measured at baseline and after each treatment cycle (weeks 6, 12, 18, and 24). Successful response was defined as ≥20% reduction from baseline penile curvature. RESULTS Overall, 832 men (CCH, n = 551; placebo, n = 281) were included in the analysis. After each cycle, mean cumulative percent reduction from baseline penile curvature was significantly greater with CCH vs placebo (P <.001). Following one cycle, 29.9% of CCH recipients exhibited a successful response. Among nonresponders, additional cycles of injections led to further successful responses: 60.8% of first cycle failures achieved response after fourth cycle (8 injections), 42.7% of cycle 1-2 failures achieved response after fourth cycle, and 23.5% of cycle 1-3 failures achieved response after fourth cycle. CONCLUSION Data showed incremental benefits from each of the 4 CCH treatment cycles. Completion of a full series of 4 CCH treatment cycles may optimize improvements in penile curvature in men with PD, including among those who did not clinically respond to previous treatment cycles.

Intralesional collagenase Clostridium histolyticum vs. verapamil injections in males with Peyronie's Disease: A prospective, matched-pair, non-blinded, randomised clinical study comparing clinical outcomes and patient satisfaction rates. Investig Clin Urol 2022; 63:563-568. [PMID: 36068002 PMCID: PMC9448666 DOI: 10.4111/icu.20220145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 06/13/2022] [Accepted: 06/22/2022] [Indexed: 11/18/2022] Open
Abstract
PURPOSE To compare clinical outcomes and patient satisfaction rates between intralesional verapamil (ILV) and collagenase Clostridium histolyticum (CCH) injections in males with Peyronie's disease (PD). MATERIALS AND METHODS Following ethics approval, PD patients were prospectively enrolled in this open-label non-blinded study. Patients were randomised to receive ILV or CCH injections with penile remodelling every fortnightly for 6 courses. Patient demographics, change in penile curvature, International Index of Erectile Function-15 and Peyronie's Disease Questionnaire (PDQ) scores as well as overall patient satisfaction and Patient Global Impression of Improvement (PGI-I) scores were recorded at pre-treatment and 6-, 12- and 24-month post-treatment. RESULTS A total of 50 males were recruited and divided into ILV (n=25) and CCH (n=25) groups. The mean changes in penile curvature were -16.8 (standard deviation [SD] 7.65) degrees in ILV and -28.2 (SD 11.5) degrees in CCH groups (p<0.01). Patients in the CCH group scored better than the ILV group on the PDQ psychosexual symptoms (-2.14 vs. -2.9; p<0.01) and symptom bother score (-3.88 vs. -4.16; p=0.08). Minor treatment-related adverse events were more common in the CCH group. The overall satisfaction rate on a 5-point scale was 4.1 in ILV and 4.5 in CCH groups, and there was no statistically significant difference in the PGI-I scores between the 2 groups (p=0.14). CONCLUSIONS CCH therapy is more effective than ILV to treat a carefully selected group of males with PD, with a reasonable safety profile and a higher high level of patient satisfaction rate in the short term.

Abstract
Treatments for Peyronie's Disease (PD) include oral medications, intralesional injections, and surgery. Collagenase Clostridium histolyticum (CCh) is the only FDA-approved treatment for PD. We sought to examine current trends in treatment of PD across the United States. Using data in the MarketScan Database, we conducted a retrospective study of men with PD in the United States. Cases were identified by ICD-9 and 10 codes, and treatments were identified using NDC and CPT codes. Treatment rates were analyzed using a linear regression model, and a Cox proportional hazard function test was performed for time-to-treatment analysis. About 27.8% of men with PD were treated within a year of diagnosis. The annual treatment rate increased from 23.2 to 35.4%, and intralesional injection was the most used treatment. Over the study period, the percentage of men receiving treatment with oral medication increased from 0.66 to 20.5%, while the use of intralesional injection and surgery decreased. Increased odds of treatment were observed in men 45-54 years (odds ratio [OR] 1.35; 95% confidence interval [CI], 1.21-1.50; p = 0) and in the southern region (OR 1.48; 95% CI, 1.39-1.56; p = 0). Trends in treatment of PD have changed over time. Intralesional injection remains the most used treatment option for men with PD.

Abstract
BackgroundPeyronie's disease (PD) is a chronic wound healing disorder, mainly involving tunica albuginea. Collagenase Clostridium Histolyticum (CCH) has shown its effectiveness in treating PD, but its efficacy and safety remain controversial, which propelled us to conduct the first evidence-based research on this topic.MethodsWe searched the Web of Science, PubMed, Embase, and ClinicalTrials.gov for related randomized controlled trials (RCTs). A systematic review and meta-analysis were performed to compare the penile curvature deformity (PCD), Peyronie's Disease Questionnaire peyronie's disease symptom bother (PDSB), penile pain score, total treatment-related adverse events (TAEs), and specific adverse events, including penile pain, penile edema, injection site pain, and contusion. Cochrane Collaboration's tool and Review Manager 5.3.0 version were applied, respectively, to evaluate the study quality and heterogeneity.ResultsFour articles (five RCTs) with 1,227 patients were finally included in the meta-analysis. The results revealed that CCH had excellent efficacy in relieving PCD (weighted mean difference [WMD]: −318.77, p < 0.001) and PDSB (WMD: −1.20, p < 0.001) compared to the placebo group, but there was no difference in the penile pain score (WMD: −0.64, P = 0.39) between the two groups. Furthermore, the incidence of TAEs in the CCH group was higher [odds ratio (OR): 12.86, p < 0.001].ConclusionsThe current evidence suggests that CCH has a significant effect on treating PD. Considering that all these adverse events are acceptable and curable, CCH could slow the disease progression in the acute phase or act as a substitute for patients unable or unwilling to undergo surgery. However, the conclusion could not be certainly drawn until RCTs with a larger scale proved it.

Abstract
Background Collagenase Clostridium histolyticum (CCH), also know as Xiaflex, with penile modeling is considered to be the gold standard non-surgical option for management of Peyronie’s disease and is known to be safe and efficacious. Corporal rupture is a rare but known adverse event of CCH treatment, however there are limited studies describing corporal herniation without rupture. Here we present a patient who experienced a rare complication following CCH injections for Peyronie’s disease: lateral herniation of the tunica albuginea in the setting of a dorsal penile plaque. Case presentation A 58-year-old male presented to our clinic seeking treatment for Peyronie’s disease. On exam, he was found to have a palpable dorsal plaque and > 30 degrees leftward curvature of the penis. He was deemed an appropriate candidate for and patient decided to proceed with CCH and modeling. He received 2 cycles of CCH injections (4 total CCH injections) with in-office and at-home penile modeling, per manufacturer’s protocol. Two weeks following in-office modeling during his second CCH cycle, the patient reported a painless, soft swelling involving the left side of his penile shaft only occurring with erection. Exam and history were suggestive of lateral herniation rather than corporal rupture. CCH was discontinued. Patient declined further evaluation with penile ultrasound. Conclusions This is the first case report detailing lateral herniation with CCH injections. Symptoms and exam that should raise suspicion of corporal herniation are a soft, painless mass with erection.

Abstract
PURPOSE OF REVIEW To review the current literature on acute management of traumatic penile fracture, with a specific discussion of those injuries following collagenase clostridium histolyticum (CCH) injections for the treatment of Peyronie's disease. RECENT FINDINGS The immediate repair of traumatic penile fracture injury is associated with significantly better prognosis for long-term sexual health. Corporal disruption following CCH administration has several distinct features, and the trend is to manage these patients conservatively in the absence of urethral injury. Traumatic penile fracture repair continues to have excellent results when performed immediately following injury. The post-CCH treatment setting portends increased difficulty during surgical management and can be successfully managed in most cases by conservative measures.

Abstract
The optimal management of suspected penile fractures post collagenase clostridium histolyticum (CCH) remains indeterminate, with some advocating for observation and others surgical repair. To address this issue, the current study sent surveys to 158 men with Peyronie's Disease (PD) who completed four CCH injection series. The survey included the Erectile Function Domain from the International Index of Erectile Function (IIEF-EFD) and questions regarding potential symptoms of corporal rupture (hematoma, popping, and detumescence). Men were categorized as having a suspected fracture (SF+) if they reported a popping sensation or rapid detumescence. All SF(+) men were managed conservatively without surgical intervention. Results were compared statistically against baseline IIEF-EFD values and between SF(+) and SF(-) groups. The key study objective was to determine whether erectile function was negatively impacted by conservative management of suspected fractures. Of the 53 returned surveys, 45 had complete data for review. The sample was statistically representative of the broader cohort of 158 men, except being older (60.0 vs 57.1 [SD 6.0 vs 9.0], p = 0.01) with shorter durations of PD (median 9 [IQR 5, 19] mo vs 13 [IQR 8, 24], p = 0.01). Overall, 7/45 (16%) of men were defined as SF(+), with all fractures occurring within 6 weeks of CCH administration. No demographic or pathophysiologic characteristics predicted SF(+). Importantly, SF(+) men did not experience worsened erectile function compared to SF(-), with a median IIEF-EFD change of +2 vs +1, p = 0.16, respectively. Curvatures were improved to a greater degree among SF(+) men (primary: median -30 [IQR -20, -32.5] vs -15 [-5, -26], p = 0.04; composite: -35 [-25, -40] vs -25 [-7, -30], p = 0.15). We concluded that suspected penile fractures in PD men undergoing CCH may be reasonably managed without surgical intervention and portend greater improvements in curvature correction.

Abstract
BACKGROUND The treatment of Peyronie's disease (PD) remains a dilemma as the true pathogenesis of PD remains an enigma. Consequently, new molecules and therapies continue to evolve. The safety and efficacy of conservative treatment for PD have not yet established. OBJECTIVES To provide the available information of the status of conservative therapy for PD. METHODS A systematic literature search was conducted using PubMed, EMBASE, and the Cochrane Library for English-language journal articles between January 2000 and July 2019, using the terms "Conservative treatment for PD", "medical treatment for PD", "non-invasive therapies for PD" and "minimally invasive therapies for PD". This systematic review was conducted in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) system. We also manually reviewed references from selected articles. The risk of bias in the included RCTs was assessed using the Cochrane Risk of Bias Assessment tool (RoB 2). RESULTS Conservative treatment is accepted as the initial treatment step in most of the cases. This kind of therapy includes various methods of treatment such as medical, non-invasive, and minimally invasive therapies. Ideal management of PD is not yet available. It is not possible to assess the value of treatment without well-designed, randomized, placebo-controlled, large-scale clinical studies. CONCLUSION Optimistically, in the near future, we may witness emergence of efficacious new agents and modalities to revolutionize medical, non-invasive, and minimally invasive treatment of this devastating condition.

Abstract
Introduction: Collagenase clostridium histolyticum (CCH) is the first and only licensed medical treatment for men with Peyronie's disease (PD). Published literature shows intralesional CCH injection as an effective and safe minimally invasive treatment in a specific subgroup of PD patients.Areas covered: The authors discuss pharmacodynamics and pharmacokinetics as well as clinical outcomes and safety profile from major CCH studies in PD. All relevant CCH studies published in PubMed and EMBASE databases up to June 2019 were included.Expert opinion: Given the variability in treatment schedule and drug access coupled with the potential need for further treatment, strict patient selection and the use of adjunctive strategies are key determinants to maximize clinical efficacy of intralesional CCH. Furthermore, longer-term follow-up data on the clinical outcomes, safety and durability of CCH in larger multi-center studies and post-marketing surveillance data are necessary to provide a comparison to other standard PD treatment options.

Abstract
Peyronie's disease is a common yet poorly understood condition characterized by penile pain, curvature, sexual dysfunction and psychological bother. Peyronie's disease represents a penile wound healing disorder, and is thought to arise from exuberant scarring in response to penile trauma in genetically predisposed men. In the absence of active treatment, the majority of men experience stable or worsening symptoms, with few reporting spontaneous resolution in penile curvature or other deformity. In contrast, penile pain improves or resolves in the majority of men. Treatment options vary based on symptom severity and stability. Several oral therapies are commonly prescribed, although to date there are no strong data to support any oral agents as monotherapy for Peyronie's disease. Other options including penile traction therapy and intralesional injections result in modest improvements for many patients, particularly when used early after symptom onset. Penile straightening through approaches, such as penile plication and plaque incision or partial excision and grafting, represent the most rapid and reliable approach to correct penile curvature once the symptoms have stabilized. Side-effects vary based on the type of surgery carried out, and include penile shortening, sensation changes and erectile dysfunction in the minority of men. In patients with drug refractory erectile dysfunction and Peyronie's disease, placement of a penile prosthesis will address both issues, and is associated with high levels of patient satisfaction. The current review provides a practical approach to the modern evaluation and management of patients presenting with Peyronie's disease.

Abstract
Peyronie's disease (PD) is a relatively common condition that can result in significant penile deformity, sexual dysfunction, and psychological bother. Surgical straightening offers the highest probability of success during the stable phase of the disease. However, for men in the acute phase of PD or for those with less severe deformity who elect to avoid surgery, a variety of non-surgical treatment options are available. Oral therapies, including L-citrulline and pentoxifylline, are most useful as part of a combination regimen rather than as monotherapy. Intralesional therapy with IFN-α2b, verapamil, and collagenase clostridium histolyticum (CCH) can cause significant reduction in penile curvature, yet these results may not be clinically significant for men with more severe curvature. Further investigation into the timing of administration and optimal patient characteristics is required. Penile traction therapy offers a clinically significant improvement in penile length and curvature. However, this has traditionally required hours of daily therapy. Overall, a combination of oral, topical, injection and traction therapies may provide the most significant benefit among the non-surgical modalities for PD.

Abstract
Peyronie’s disease is a condition that causes abnormal healing of the tunica albuginea, causing penile curvature. It is difficult to treat and its management is continuing to evolve. Proposed non-surgical treatments have included oral, topical, intralesional, extracorporeal shockwave, and traction therapy. The study of Peyronie’s disease is made difficult by heterogeneity in the timing of presentation, severity and characteristics of deformity, and associated complaints. Moreover, meta-analyses of studies are difficult due to inconsistencies across study endpoints and the duration of treatments. This article reviews the current clinical evidence and guideline recommendations, with a focus on an improvement in penile curvature.

Variation in collagenase Clostridium histolyticum practice patterns: a Survey of ISSM Members. Int J Impot Res 2019; 31:439-443.

Abstract
Collagenase clostridium histolyticum (CCH, Xiaflex, Xiapex) is the only FDA-approved medication for treatment of Peyronie's disease. It is unclear how practitioners actually use CCH in their own practices. The objectives of the study were: (1) to identify variability in practice patterns for CCH among practitioners, (2) to assess adherence to the package insert instructions, and (3) to evaluate whether provider satisfaction was associated with adherence to instructions. A 30-question online survey was distributed to 1270 members of the International Society for Sexual Medicine (ISSM) from the EU, USA, Canada and Australia. Of the 30 questions, 10 survey questions had only one response consistent with the CCH package insert recommendations. An "adherence" score was calculated for each survey participant depending on how many of these questions were answered correctly. The average adherence scores of various groups were compared using a student's t-test. A chi-squared test was used to determine association between categorical variables. Of 202 total responses, 132 practitioners reported using CCH out of 1270 ISSM members from countries where CCH is available (10.4% response rate). Practitioners from outside the USA were more likely to be satisfied with CCH (p = 0.006), and more experienced users (>20 uses) were more likely to be satisfied than less experienced users (<10 uses) (p = 0.046). Satisfied users of CCH did not have significantly different adherence scores than non-satisfied users. Even though 67% of practitioners believed they followed the package insert guidelines, only 11% adhered to all the recommendations evaluated by the survey. Treatment adherence to package insert guidelines does not appear to be associated with provider satisfaction. We believe there is utility in seeing a snapshot of these practice patterns so practitioners may feel more comfortable adapting their own practice in light of newer data supporting alternative administration methods.

Abstract
Peyronies disease (PD) is estimated to affect approximately 3-9% of men worldwide and maybe associated with pain, erectile dysfunction and penile deformity including shortening. The condition has significant debilitating effects on quality of life, self-esteem and psychological wellbeing in addition to sexual function. Surgical results add further to this by patients having dissatisfaction with various aspects of outcomes. Non-surgical management may allow patients to avoid the morbidities associated with surgery and still achieve improved functional and aesthetic outcomes. Several non-surgical options are currently being employed in the treatment of PD that may reduce or stabilize both objective measures (e.g. penile length and deformity) and subjective measures (including sexual function, pain and partner satisfaction). Nonsurgical management can allow patients to avoid the morbidities associated with surgery and still achieve improved functional and aesthetic outcomes. In this article we explore the current non-surgical management options for PD including oral, mechanical therapies, intralesional and topical treatments. We also briefly discuss future treatment options in the form of stem cell therapy.

Abstract
Purpose We evaluated the impact of collagenase clostridium histolyticum (CCH) on rates of diagnosis, treatment, and corporal rupture in Peyronie's disease (PD). We examined the impact of CCH on cost of PD treatment. Materials and Methods We extracted data on PD diagnosis (ICD-9 607.95 and ICD-10 N48.6), corporal rupture (ICD-9 959.13 and ICD-10 S39.840A), CCH use (J0775), penile injections (CPT 54200), and corporal rupture repair from 2008 to 2016 in men over 40 years old using the Clinformatics® Data Mart Database (3.7 to 4.9 million males). We analyzed for prevalence of PD, rates of PD treatments, cost associated with treatment, and rates of corporal rupture and repair by year. Results The prevalence of PD was 0.29% in 2013 and did not increase after CCH entered the market in 2014. An average of 2.52% of men with PD received treatment before CCH, compared with 3.75% after (p<0.0001). Penile injection rates increased (1.34% vs. 2.61%, p<0.0001), while rates of surgical treatments decreased between these periods. There was no change in rate of corporal rupture in men with PD before (0.024%) and after (0.024%) CCH. Overall, only 20.0% of corporal ruptures were repaired. After CCH entered practice, a significant increase in cost occurred (p=0.013). Conclusions The prevalence of men with PD did not change after CCH. However, more men with PD received treatment due to an increase in penile injections. The cost of treating PD increased after CCH became available. The overall prevalence of corporal rupture did not change after CCH entered the market.

Abstract
Collagenase clostridium histolyticum (CCH) was approved for the treatment of Peyronie's disease (PD) in December of 2013. Recently, further research has supported its use. The aim of this study was to objectively evaluate the effects of CCH on penile curvature associated with Peyronie's disease at our high volume institution. Since the approval of CCH for PD, 45 men have undergone between 1 and 4 treatment cycles (mean 3.13, standard deviation (SD) = 0.87) at our institution. Primary as well as secondary curvature, if any, was measured before beginning therapy and after each cycle of therapy. The degree of curvature was compared. We also questioned these men about their subjective experience with CCH. The mean age of this cohort was 55.7 years (range 35-70). The mean primary curvature was 53.6° (SD = 16.5). Post-treatment mean primary curvature was 48.2° (SD = 19.5), p = 0.10. Secondary curvature was reduced from 24.1° (SD = 11.3) to 20.4° (SD = 11.5) before and after treatment with CCH, respectively, p = 0.27. There were two tunical ruptures in this series after which both ceased therapy with CCH. Additionally, 37/45 patients in this series expressed some degree of dissatisfaction in their post-therapy visits with most of these men stating that they did not notice a change in their curvature. CCH remains an option for the treatment of PD. Predictors of success, however, are lacking. Our experience showed a less-robust response to CCH than previous studies and underscores the need for effective and clear patient counseling prior to the initiation of therapy with CCH for PD in the post-FDA-approval setting.

Abstract
Numerous treatments have been proposed for Peyronie's disease (PD). As the evidence base has expanded, the field of operative and non-operative options for patients has narrowed. Collagenase clostridium hystolyticum (CCH) injection now comprises the medical option, and surgical possibilities entail penile plication, plaque incision/excision and grafting, and prosthesis implantation. Still, questions abound regarding the optimal approach and indication for each of these treatments. We conducted a review of literature exploring the contemporary management of PD with a particular focus on work since the last American Urologic Association's (AUA) guidelines update for PD. Recent results and discussion indicate trends toward minimal invasiveness, toward a more holistic approach to the PD patient, and away from algorithmic management, galvanized, in part, by data challenging long-held beliefs.
