Introducción: La enfermedad de la Peyronie resulta poco común e involucra a hombres de mediana edad. Objetivo: Caracterizar los aspectos clínicos y epidemiológicos de los pacientes con enfermedad de la Peyronie infiltrados con células mononucleares. Métodos: Se realizó un estudio observacional, analítico, longitudinal prospectivo en el Hospital General Docente "Comandante Pinares" desde junio de 2015 hasta mayo de 2018, con una muestra de 159 pacientes. Se controlaron las variables de edad, color de la piel, factores etiológicos, curvatura y desviación del pene además de síntomas y signos. Resultados: El mayor número de pacientes correspondieron a la edad de 50-59 años, de piel blanca, grados de curvatura entre 20o y 39o. Después del tratamiento 115 pacientes se encontraron con curvatura menor a 20o y desviación dorsal. Las causas más frecuentes de los microtraumas a nivel de pene resultan durante al acto sexual o en estado flácido del pene (105/159). La diabetes mellitus y la hipertensión arterial, con 59,7 y 30,8 por ciento, respectivamente resultan los factores etiológicos más frecuentes; los síntomas y signos fueron el dolor y la curvatura, 115 pacientes presentaron ausencia de dolor al hacer la comparación de la media al concluir el tratamiento, resultando significativo (p= 0,0000). Conclusiones: La enfermedad de la Peyronie resulta frecuente en pacientes de la quinta década de la vida, con color de piel blanca. La causa más frecuente son los microtraumas en la actividad sexual, la diabetes mellitus y la hipertensión arterial como antecedentes patológicos personales. Existe mejoría de la sintomatología en los pacientes infiltrados con células mononucleares(AU)

Introduction: Peyronie's disease is rare and involves middle-aged men. Objective: To characterize the clinical and epidemiological aspects of patients with Peyronie's disease infiltrated with mononuclear cells. Methods: An observational, analytical, prospective longitudinal study was carried out at the "Comandante Pinares" General Teaching Hospital from June 2015 to May 2018, with a sample of 159 patients. The variables of age, skin color, etiological factors, curvature and deviation of the penis, as well as symptoms and signs, were controlled. Results: The largest number of patients corresponded to the age of 50-59 years, white skin, degrees of curvature between 20o and 39o. After treatment, 115 patients were found to have curvature less than 20o and dorsal deviation. The most frequent cause of penile microtrauma is during sexual intercourse or in the flaccid state of the penis (105/159). Diabetes mellitus and arterial hypertension, with 59.7 and 30.8 percent, respectively, are the most frequent etiological factors; the symptoms and signs were pain and curvature, 115 patients presented absence of pain when comparing the mean at the end of the treatment, being significant (p= 0.0000). Conclusions: Peyronie's disease is frequent in patients of the fifth decade of life, with white skin color. The most frequent cause are microtraumas in sexual activity, diabetes mellitus and arterial hypertension as personal pathological antecedents. There is improvement of the symptoms in patients infiltrated with mononuclear cells(AU)

Effects of plication procedures in special cases of Peyronie's disease: a single-center retrospective study of 72 patients / 亚洲男科学杂志(英文版)

General recommendations regarding surgical techniques are not always appropriate for all Peyronie's disease (PD) patients. Therefore, the purpose of this study was to investigate the effects of plication procedures in PD patients with severe penile curvature and the effects of early surgical correction in patients who no longer have progressive deformities. The clinical data from 72 patients who underwent plication procedures were analyzed in this study. Patients were divided into Groups A and B according to the curvature severity (≤60° or >60°) and Groups 1 and 2 according to the duration of disease stabilization (≥3 months or <3 months). At the 1-year follow-up, 90.0% (36/40) and 90.6% (29/32) patients reported complete penile straightening, and 60.0% (24/40) and 100.0% (32/32) patients reported penile shortening in Groups A and B, respectively. No curvature recurrence occurred in any patient, and no significant differences were observed in postoperative International Index of Erectile Function-Erectile Function domain (IIEF-EF), erectile pain, sensitivity, or suture knots on the penis whether such outcomes were grouped according to the curvature severity or the duration of stabilization. However, the duration from symptom onset to surgical management in Group 1 was significantly longer than that in Group 2 (mean ± standard deviation [s.d.]: 20.9 ± 2.0 months and 14.3 ± 1.2 months, respectively, P < 0.001). The present study showed that the plication procedures seemed to be an effective choice for the surgical treatment of PD patients with severe penile curvature. In addition, the early surgical treatment seemed to benefit those patients who already had no erectile pain and no longer exhibited progressive deformity.

Low-intensity extracorporeal shock wave therapy for Peyronie's disease: a single-center experience / 亚洲男科学杂志(英文版)

The aim of this article is to assess the outcomes of a low-intensity extracorporeal shock wave therapy (LiESWT) protocol for the treatment of Peyronie's disease (PD). Patients treated for PD were prospectively recorded, and data were retrospectively reviewed. Age, characteristics of fibrous plaques, concomitant treatments, International Index of Erectile Function (IIEF-5), Lue score, and pain score on Likert scale were collected. Patients in acute phase of PD and an angulation of <40° were included. The protocol consisted of 6 weekly sessions of 4000 pulses each, applied from different directions, with a maximal power of 20 W and 8 Hz frequency. We included 39 patients (median age: 56.8 years, interquartile range [IQR]: 35.8-62.2 years). The median number of sessions received per patient was 7.2. After treatment, the median Lue score decreased from 6.8 initially to 3.3 (P = 0.003), the median Likert pain score dropped from 1.8 to 0.7 (P = 0.004), the median plaque size was reduced from 2 cm to 1.2 cm (P = 0.08), and the median penile curvature diminished from 31° to 17° (P = 0.07). On univariate and multivariate analysis, the only predictors of success were younger age (odds ratio [OR] = 0.95, P = 0.03 and OR = 0.91, P = 0.04, respectively) and concomitant use of phosphodiesterase-5 inhibitors (PDE5i; OR = 0.92, P = 0.02 and OR = 0.93, P = 0.01, respectively). LiESWT had a favorable impact on Lue score and notably penile pain, curvature, plaque size, and erectile function in patients treated for PD during the early inflammatory phase, with no side effects. Younger age and concomitant use of PDE5i were the only success predictors.

Desafios e importância da avaliação pré-operatória na doença de Peyronie / Challenges and importance of the preoperative evaluation in Peyronie's disease

A doença de Peyronie, notória desde 1743, segue sendo um grande desafio na prática médica, com prevalência relevante e grande impacto na vida sexual dos casais. O tratamento cirúrgico é a principal modalidade terapêutica capaz de restabelecer a vida sexual nos pacientes com doença de Peyronie significativa. A escolha do momento de implementação do tratamento cirúrgico, bem como a escolha da técnica a ser empregada, varia de acordo com três pontos centrais: a fase da doença, a deformidade apresentada e a função erétil. Estes pilares para a decisão terapêutica do paciente com doença de Peyronie possuem nuances, não sendo simples a caracterização destes fatores em muitos casos. Uma avaliação pré-operatória criteriosa, fundamental para a melhor escolha terapêutica, exige experiência e um conhecimento aprofundado sobre o tema. O objetivo do presente artigo é promover uma ampla discussão acerca de fatores primordiais da avaliação pré-operatória de pacientes com doença de Peyronie.

Utilización de pentoxifilina en fase aguda de enfermedad de La Peyronie / Use of Pentoxifylline in the acute phase of Peyronie's disease

INTRODUCCIÓN: existe una gran variedad de tratamientos orales para la Enfermedad de La Peyronie (EP), pero ninguno demostró ser efectivo. En los últimos años se ha propuesto a la Pentoxifilina (PTX) como un potencial agente para su tratamiento. OBJETIVO: evaluar la evolución clínica de los pacientes que recibieron PTX al menos 3 meses durante la fase aguda de la EP. MATERIALES Y MÉTODOS: estudio de cohorte retrospectivo y observacional. Los datos se obtuvieron de las historias clínicas de pacientes con diagnóstico de EP entre enero y octubre de 2017. Para la evaluación objetiva, se utilizaron autofotografías y técnica de Kelami. RESULTADOS: 93 hombres cumplieron con los criterios de inclusión. El tiempo medio de tratamiento con PTX fue de 7,9 meses, y el de seguimiento, 10,8 meses. El 59,1% de los pacientes no tuvo modificaciones en su curvatura, el 9,7% mejoró, mientras que el 31,2% empeoró. De 49 pacientes que penetraban sin dificultad, 34 (69,4%) no tuvieron cambios, 12 (24,5%) pasaron a tener dificultad y 3 (6,1%) se convirtieron en no penetradores (p 0,0001). De los 41 pacientes que tenían dificultad en la penetración, 13 (31,7%) pudieron penetrar sin dificultad, 7 (17,1%) pasaron a no poder hacerlo, mientras que el resto (21 pacientes) se mantuvo sin cambios (p 0,0001). La correlación entre la curvatura inicial y la curvatura luego del tratamiento medido en todos los pacientes fue significativa (p 0,028). CONCLUSIÓN: la PTX podría tener un efecto positivo en estabilizar la enfermedad, y los hombres con EP en fase aguda podrían beneficiarse con el tratamiento.

INTRODUCTION: There is a wide variety of oral treatments for Peyronie's Disease (PD) but none proved to be effective. In recent years, Pentoxifylline (PTX) has been proposed as a potential agent for the treatment. Objective: To evaluate the clinical evolution of patients who received PTX at least 3 months during the acute phase of PD. MATERIALS AND METHODS: Retrospective and observational cohort study. The data were obtained from the clinical records of patients diagnosed with PE between January 2007 and October 2017. For their objective evaluation, autographs and the Kelami technique were used. RESULTS: 93 men met the inclusion criteria. The mean time of treatment with PTX was 7.9 months and the follow-up time was 10.8 months. 59.1% of patients had no changes in their curvature, 9.7% improved, while 31.2% worsened. Of 49 patients who entered without difficulty in penetrating, 34 (69.4%) had no changes, 12 (24.4%) had difficulty and 3 (6.1%) became non-penetrators (p 0.0001). Of the 41 patients who had difficulty in penetrating, 13 (31.7%) could penetrate without difficulty, 7 (17.1%) were unable to do so, while the rest (21 patients) remained unchanged (p. 0.0001). The correlation between initial curvature and curvature after treatment measured in all patients was significant (p 0.028). CONCLUSION: PTX could have a positive effect in stabilizing the disease and men with acute phase PE could benefit with treatment.

Stem cells for the treatment of Peyronie's disease / 中华男科学杂志

Peyronie's disease (PD) is a connective tissue disorder characterized as fibrotic plaque localized in the tunica albuginea (TA), and its pathomechanism remains obscure. Endeavors are being made to explore effective and minimally invasive therapeutic strategies for PD, and some experimental studies have verified the preventative and therapeutic effects of stem cells (SC), especially adipose tissue-derived SCs (ADSC), on this disease and excavated some of their action mechanisms. Some scholars attempted the integration of SCs with graft tissues, aiming at the improvement of TA grafting and reconstruction. The only publicly available clinical trial of SC therapy for PD was encouraging, and further on-coming relevant researches are expected with simultaneous optimization of the scheme. In a word, the application of SCs in the prevention and treatment of PD is a promising topic for clinical research, and there remain quite a lot of unknowns to be explored. This article summarizes the existing researches in this field.

Penile Reconstructive Surgery in Peyronie Disease: Challenges in Restoring Normal Penis Size, Shape, and Function

Tratamento da Doença de Peyronie com hipertermia, vitamina D e testosterona ­ Estudo piloto randomizado controlado / TREATMENT OF PEYRONIE'S DISEASE WITH HYPERTERMIA, VITAMIND AND TESTOSTERONE ­ A PILOT RANDOMIZED CONTROLLED TRIAL

A doença de Peyronie caracteriza-se pela presença de placas de fibrose no pênis, com ou sem curvatura, estrangulamento e encurtamento do pênis e, em muitos casos, disfunção erétil. O objetivo deste trabalho foi verificar a eficácia da combinação de hipertermia usando laser infravermelho (aplicado pelo próprio paciente), testosterona intramuscular e gel 10% diretamente no pênis e vitamina D por via oral VS hipertermia isolada usando o mesmo regime de laser infravermelho. Vinte pacientes que preencheram os critérios de inclusão foram randomizados em dois grupos de dez pacientes. Os dois grupos apresentaram significativa diminuição da placa. Conclusão: este estudo piloto demonstrou que a hipertermia usando laser infravermelho isoladamente pode ser um método promissor para tratar a doença de Peyronie

Extracorporeal Shock Wave Therapy in Peyronie's Disease: Clinical Efficacy and Safety from a Single-Arm Observational Study

PURPOSE: In this study, we aimed to determine the role of extracorporeal shockwave therapy (ESWT) in the management of Peyronie's disease (PD). MATERIALS AND METHODS: A total of 325 patients suffering from PD were enrolled in this single-arm clinical study. All patients were received ESWT using a schedule of 1 treatment/wk. Penile curvature was measured by a goniometer after intracavernosal drug-induced erection using Alprostadil. Plaque size was measured with a ruler and sexual function assessed by the international index of erectile function (IIEF)-15 score. Severity of erectile dysfunction was classified as severe (IIEF-15 ≤10), moderate (IIEF-15 between 11 and 16), or mild (IIEF-15 between 17 and 25). Results were evaluated at baseline and 3 months after the treatment. RESULTS: All the patients completed the study protocol. Median age was 59.0 years (55.0–64.0 years). After treatment, the median (interquartile range, IQR) plaque size reduced from 1.78 cm2 (1.43–2.17 cm2) to 1.53 cm2 (1.31–1.96 cm2) (p<0.001); the median (IQR) penile length in erection increased from 13.0 cm (12.0–14.0 cm) to 14 cm (13.0–15.0 cm) (p<0.001) and the median (IQR) penile curvature from 30.4° (22.2°–35.4°) to 25.0° (20.2°–30.4°) (p<0.001). We also observed a decrease in pain assessed by visual analogue scale (7 vs. 3; p<0.001), an improvement in each of the IIEF sub-domains (p<0.001) and an improvement in all three PD questionnaire domains (p<0.001). CONCLUSIONS: Based on our findings, ESWT could be considered a safe and efficient minimally invasive option for the management of the patients suffering from PD.

Diagnosis and treatment of sexual dysfunction in elderly men

Male sexual dysfunction refers to a phenomenon in which a man experiences difficulty at any stage during the process of sexual intercourse. In general, erectile dysfunction is regarded as the most representative form of sexual dysfunction, but various other diseases can also be categorized as male sexual dysfunction, including sexual arousal disorder, decreased libido, ejaculation disorder, and Peyronie's disease. Causes of sexual dysfunction include chronic diseases, such as diabetes, hypertension, dyslipidemia, and obesity. In addition, some medications, surgical procedures, and traumas can cause sexual dysfunction. However, aging is the most important cause of male sexual dysfunction. To diagnose and treat elderly patients who complain of male sexual dysfunction, it is first necessary to become familiar with the characteristics of sexual dysfunction in elderly men. The prevalence rates of metabolic syndrome, hypertension, diabetes, dyslipidemia, coronary artery disease, stroke, and depression are higher among elderly men than among younger men; furthermore, the elderly are at a higher risk for the development of kidney, hepatic, spinal cord, and neurological diseases. Notably, anti-hypertensive agents can affect erectile function in elderly men: sexual dysfunction may be severe or the response to treatment may be poor. For satisfactory treatment, spousal factors should also be considered.

The Impact of Clostridium Histolyticum Collagenase on the Prevalence and Management of Peyronie's Disease in the United States

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.

Objective measurements of the penile angulation are significantly different than self-estimated magnitude among patients with penile curvature

ABSTRACT Introduction: The study was aimed to assess the presence of actual differences between the objective and the perceived magnitude of a curvature between patients affected by Peyronie's disease (PD) and congenital penile curvature (CPC). Materials and Methods: Wee analysed a cohort of 88 consecutive patients seeking medi- cal help for either CPC or PD. All patients were invited to provide a self-made drawing of their penis in erection in order to obtain self-provided description of the deformity. An objective measurement of the deformity was also performed drawing two intersecting lines through the center of the distal and proximal straight section of the penile shaft. Results: Our findings showed significant differences between patient self-estimation and the objective measurements of the penile angulation performed by trained experts, with only 32% of patients correctly assessing their own curvature. Overall, patients tended to overestimate (56%) their degree of curvature, but the results are different in patients with PD than those with CPC. In the 60 men (68%) who did not accurately assess their curvature, PD patients generally overestimated their curvature versus CPC patients (67% vs 16%). On the contrary CPC patients underestimated their curvature compared to PD (42% vs. 4%). Conclusion: In order to improve patients' satisfaction rates, the surgeon needs to take into consideration the patient's perception of the deformity when planning the type of surgical correction.

Sonographic patterns of Peyronie's disease in patients with absence of palpable plaques

ABSTRACT Purpose Non-palpable isolated septal plaques of the penis are likely present in a significant number of patients affected by erectile dysfunction (ED) and penile pain without deformity or curvature. The aim of this study was to evaluate the ultrasound (US) patterns observed in patients investigated for ED or penile pain without curvature. Materials and Methods We reviewed the medical records of 386 patients who underwent an initial colour-Doppler ultrasonography (CDU) of the penis for DE and/or penile pain without curvature. After satisfying inclusion criteria, 41 patients were individualized. All patients had a non-palpable plaque with involvement of the penile septum. Three US patterns were identified: focal hyperecoic thickening of the intercavernosum septum (IS) with acoustic shadow (pattern 1), non-calcified thickening (isoechoic or slightly hyperechoic (pattern 2), and microcalcifications in the IS without associated acoustic shadow (pattern 3). Results Patients' mean age was 51.3±16.7. ED was the predominant disorder in 73.2% of patients, followed by penile pain and length loss in 19.5% and 7.3% of patients, respectively. 32(78.1%) patients showed the pattern 1, 6 (14.6%) pattern 2, and 3 (7.3%) pattern 3. Plaques size varied from 3 to 13 mm. The penile hemodynamic response to CDU reported abnormal findings distally to the septal plaques in 20 patients (<25cm/sec). Median left and right cavernosum artery flows measured a peak systolic velocity of 31cm/sec and 33 cm/sec, respectively. Conclusions We believe that an US study with CDU provides a way to characterize, localize, and deliver treatment choice in patients with Peyronie's Disease.

A new technique, combined plication-incision (CPI), for correction of penile curvature

ABSTRACT Introduction Penile curvature (PC) can be surgically corrected by either corporoplasty or plication techniques. These techniques can be complicated by post-operative: penile shortening, recurrent PC, painful/palpable suture knots and erectile dysfunction. Objective To avoid the complications of corporoplasty and plication techniques using a new technique: combined plication-incision (CPI). Materials and Methods Two groups (1&2) were operated upon: group 1 using CPI and group 2 using the 16-dot technique. In CPI, dots were first marked as in 16 dot technique. In each group of 4 dots the superficial layer of tunica albuginea was transversely incised (3-6mm) at the first and last dots. Ethibond 2/0, passed through the interior edge of the first incision plicating the intermediate 2 dots and passed out of the interior edge of the last incision, was tightened and ligated. Vicryle 4/0, passed through the exterior edges of the incisions, was tightened and ligated to cover the ethibond knot. Results Twelve (57.1 %) participants in group 2 complained of a bothering palpable knot compared to none in group 1 with statistically significant difference (P=0.005). Postoperative shortening (5mm) of erect penis, encountered in 9 participants, was doubled in group 2 but with insignificant difference (P>0.05). Post-operative recurrence of PC, was encountered in only 1 (4.8%) participant in group 2, compared to none in group 1, with insignificant difference (P>0.05). Post-operative erectile rigidity was normally maintained in all participants. Conclusion The new technique was superior to the 16-dot technique for correction of PC.

Penile Doppler ultrasonography revisited

Penile Doppler ultrasonography is a high-performing, noninvasive or minimally-invasive imaging modality that allows the depiction of the normal anatomy and macroscopic pathologic changes in real time. Moreover, functional changes in penile blood flow, as seen in erectile dysfunction (ED), can be analyzed using color Doppler ultrasonography (CDUS). This review article describes the normal sonographic anatomy of the penis, the sonographic technique for evaluating ED, the normal phases of erection, and the various causes of ED. Additionally, we describe the interpretation of different parameters and findings on penile CDUS for the diagnosis and classification of ED, priapism, and Peyronie disease.
