Introduction. Peyronie's disease is an acquired malformation of the penis, caused by the deposition of fibrotic plaques in the tunica albuginea. The prevalence in the United States ranges between 0.39% and 11.8%, in Europe 8.9%, in Latin America there is no specific percentage of current prevalence due to the scarcity of reports of this pathology. This bibliometric analysis seeks to describe the therapeutic evolution of Peyronie's Disease in the literature over the last 62 years, as well as the geographic distribution of these publications. Methodology. This is an observational, descriptive study, with a bibliometric analysis from 1957 to 2019, using GoPubMed and FABUMED. Results. 721 references on surgical treatment in Peyronie's disease were obtained, with an increase in scientific production throughout the study period. The Journal of Urology was the journal with the highest number of publications, 57.9% within the scientific article category. The leading country was the United States with 191 publications. Discussion. There is a limited amount of literature on therapeutic advances for the treatment of Peyronie's disease, which makes it difficult to compare research over the years in different areas of the world. Research in Latin America is scarce. Conclusion. Research on surgical treatment in Peyronie's disease shows an increasing pattern in scientific productivity over the years. Countries with higher economic income have greater development in the subject and to a lesser extent regions with limited resources. The analysis shows the importance of increasing scientific production in Colombia, as well as stimulating research on this topic, since there are few publications on the evolution of surgical treatment for this disease.

Orchio-Septopexy: A new technique to cover and fix detorsed testis undergoing fasciotomy of tunica albuginea

ABSTRACT Purpose Compartment Syndrome (CS) has been recognized as a potential factor that worsens testicular viability after detorsion, especially in borderline cases of prolonged ischemia. Fasciotomy of the testicular tunica albuginea to relieve the pressure associated with CS has been proposed to accommodate edema after detorsion, embracing the raw fasciotomy area with tunica vaginalis flap (TVF) or graft. Fashioning the TVF can be tedious in cases of severe scrotal edema. Herein we present a technique that facilitates and expedites the procedure, maintaining the fasciotomy area decompressed. Materials and Methods In testicular torsion, where the testis remains with dark coloration and questionable viability after detorsion a longitudinal releasing incision is made in the tunica albuginea (fasciotomy) to decrease compartmental pressure. If signs of parenchymal recovery (bleeding points, better color) are seen an orchio-septopexy is performed, suturing the incised albuginea's edges to the septum with a running suture, avoiding CS as well as re-torsion. Results Orchio-septopexy was performed in 11 cases with a mean age of 11.9 years (3-17). All cases had clinic follow-up and testicular Doppler US with a mean of 9.5 months (6-24). 6/11 cases (54%) were salvaged, with good vascularity in the Doppler US and maintained more than 50% testicular volume compared to the contralateral side. Conclusion Orchio-septopexy after testicular fasciotomy is a simple and fast technique that can be utilized in cases of prolonged testicular ischemia and questionable viability. More than half of the testes recovered, encouraging us to propose its utilization as well as its validation by other surgeons.

Future considerations in prosthetic urology / 亚洲男科学杂志(英文版)

Since their popularization, genitourinary prosthetics have remained a gold-standard therapy for the treatment of erectile dysfunction and stress urinary incontinence and in cases of testicular loss or dysfunction. They have also represented an area of significant innovation, which has contributed to excellent long-term outcomes. Given this history, the objective of the current review was to provide a 5-10-year outlook on anticipated trends and developments in the field of genitourinary prosthetics. To accomplish this objective, a PubMed and patent search was performed of topics relating to penile and testicular prostheses and urinary sphincters. In regard to penile prostheses, findings demonstrated several new concepts including temperature-sensitive alloys, automated pumps, devices designed specifically for neophalluses, and improved malleable designs. With artificial urinary sphincters, new concepts include the ability to add or remove fluid from an existing system, two-piece systems, and new mechanisms to occlude the urethra. For testicular prosthetics, future implementations may not only better replicate the feel of a biological testicle but also add endocrinological functions. Beyond device innovation, the future of prosthetics is also one of expanding geographic boundaries, which necessitates variable cost modeling and regulatory considerations. Surgical trends are also changing, with a greater emphasis on nonnarcotic, postoperative pain control, outpatient surgeries, and adjunctive techniques to lengthen the penis and address concomitant stress incontinence, among others. Concomitant with device and surgical changes, future considerations also include a greater need for education and training, particularly given the rapid expansion of sexual medicine into developing nations.

Evaluation of relaxant responses properties of cinnamon essential oil and its major component, cinnamaldehyde on human and rat corpus cavernosum

ABSTRACT Cinnamomum cassia (Cinnamon) is a well-known traditional medicine with therapeutic benefits for centuries. We evaluated the effects of cinnamon essential oil (CEO) and its main component cinnamaldehyde (CA) on human corpus cavernosum (HCC) and rat CC. The essential oil of cinnamon was analyzed for the confirmation of the oil profile. HCC specimens from patients undergoing penile prosthesis surgery (age 48-69 years) were utilized for functional studies. In addition, erectile responses in anesthetized control and diabetic rats were evaluated in vivo after intracavernosal injection of CEO and CA, and rat CC strips were placed in organ baths. After precontraction with phenylephrine (10µM), relaxant responses to CEO and CA were investigated. CA (96.9%) was found as the major component. The maximum relaxation responses to CEO and CA were 96.4±3.5% and 96.0±5.0% in HCC and 97.5±5.5% and 96.8±4.8% in rat CC, respectively. There was no difference between control and diabetic rats in relaxation responses to CEO and CA. The relaxant responses obtained with essential oil and CA were not attenuated in the presence of nitric oxide synthase (NOS) inhibitor, and soluble guanylate cyclase inhibitor (sGS) in CC. In vivo, erectile responses in diabetic rats were lower than in control rats, which was restored after intracavernosal injection of CEO and CA. CEO and CA improved erectile function and relaxation of isolated strips of rat CC and HCC by a NO/cGMP-independent mechanism. Further investigations are warranted to fully elucidate the restorative effects of CEO and CA on diabetic erectile dysfunction.

Value of ultrasound in diagnosis of Peyronie's disease / 中国医学影像技术

Objective To investigate the value of ultrasound in diagnosis of Peyronie's disease (PD). Methods The ultrasonic characteristics of 48 PD patients were analyzed, and numbers of penile plaques detected with ultrasound and clinical palpation were compared. Results Totally 66 penile plaques were detected with clinical palpation and 80 plaques were detected with ultrasound (Z=1.812 5, P<0.05). Among 80 plaques detected with ultrasound, 48 (48/80, 60.00%) showed medium and high echo, 24 (24/80, 30.00%) showed strong echo, 6 (6/80, 7.50%) were hypoechoic, and 2 plaques (2/80, 2.50%) were hyperechoic accompanied calcification. Strip or punctate blood flow signals were found in the periphery of 4 plaques and the interior of 5 plaques, while strip blood flow signals were detected in the interior and periphery of 1 plaque. Two PD patients accompanied with penile arterial insufficiency, and 1 accompanied with penile veno-occlusive dysfunction. Conclusion Ultrasound is superior to palpation in the detection of penile plaque in PD patients,which can detect blood flow inside and around the plaques and evaluate penile vascular function in patients with erectile dysfunction, providing a basis for clinical treatment and prognostic evaluation of PD.

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.

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.

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.

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.

Silencing Histone Deacetylase 7 Alleviates Transforming Growth Factor-β1-Induced Profibrotic Responses in Fibroblasts Derived from Peyronie's Plaque

PURPOSE: Epigenetic modifications, such as histone acetylation/deacetylation and DNA methylation, play a crucial role in the pathogenesis of inflammatory disorders and fibrotic diseases. The aim of this study was to study the differential gene expression of histone deacetylases (HDACs) in fibroblasts isolated from plaque tissue of Peyronie's disease (PD) or normal tunica albuginea (TA) and to examine the anti-fibrotic effect of small interfering RNA (siRNA)-mediated silencing of HDAC7 in fibroblasts derived from human PD plaque. MATERIALS AND METHODS: For differential gene expression study, we performed reverse-transcriptase polymerase chain reaction for HDAC isoforms (1–11) in fibroblasts isolated from PD plaque or normal TA. Fibroblasts isolated from PD plaque were pretreated with HDAC7 siRNA (100 pmol) and then stimulated with transforming growth factor-β1 (TGF-β1, 10 ng/mL). Protein was extracted from treated fibroblasts for Western blotting. We also performed immunocytochemistry to detect the expression of extracellular matrix proteins and to examine the effect of HDAC2 siRNA on the TGF-β1-induced nuclear translocation of Smad2/3 and myofibroblastic differentiation. RESULTS: The mRNA expression of HDAC2, 3, 4, 5, 7, 8, 10, and 11 was higher in fibroblasts isolated from PD plaque than in fibroblasts isolated from normal TA tissue. Knockdown of HDAC7 in PD fibroblasts inhibited TGF-β1-induced nuclear shuttle of Smad2 and Smad3, transdifferentiation of fibroblasts into myofibroblasts, and abrogated TGF-β1-induced production of extracellular matrix protein. CONCLUSIONS: These findings suggest that specific inhibition of HDAC7 with RNA interference may represent a promising epigenetic therapy for PD.

An unanswered question in pediatric urology: the post pubertal persistence of prepubertal congenital penile curvature correction by tunical plication

ABSTRACT Objective: The aim of this study is to analyze post pubertal results of pre pubertal tunica albuginea plication with non-absorbable sutures in the correction of CPC. Materials and Methods: The files of patients who underwent tunica albuginea plication without incision (dorsal/lateral) were retrospectively reviewed. Patients younger than 13 years of age at the time of operation and older than 14 years of age in November 2015 were included. Patients with a penile curvature of less than 30 degrees & more than 45 degrees and penile/urethral anomalies were excluded. All of the patients underwent surgery followed by circumcision. Results: The mean age of patients at the time of the operation was 9.7 years (range, 6-13 years). The mean degree of ventral penile curvature measured during the operation was 39 degrees while it was 41 degrees in the lateral curvatures. All of the patients were curvature-free at the end of the operation. At the time of the follow-up examination, the mean age was 16.7 years (range, 14-25 years). Six patients had a straight (0-10 degrees) penis during erection and seven patients had recurrent penile curvatures ranging from 30 to 50 degrees. Conclusion: Pre pubertal tunica albuginea plication of congenital penile curvature (30-45 degrees) with non-absorbable sutures performed without incision is a minimal invasive method especially when performed during circumcision. However, recurrence might be observed in half of the patients after puberty.

Collagenase Clostridium Histolyticum in the Treatment of Peyronie's Disease: Review of a Minimally Invasive Treatment Option

Peyronie's disease (PD) is an inflammatory disorder characterized by an abnormal collagen deposition in the tunica albuginea of the penis, leading to fibrous and non-compliant plaques that can impede normal erection. Although pharmacological treatments are available, only intralesional injection therapy and surgical reconstruction have demonstrated tangible clinical efficacy in the management of this condition. Intralesional injection of collagenase clostridium histolyticum (CCH) has come to the forefront of minimally invasive treatment of PD. In this review, the authors provide an update on the safety, efficacy, and indications for CCH. The efficacy of CCH will be assessed on the basis of improvement in the severity of penile fibrosis, curvature, and pain. Numerous well-designed clinical trials and post-approval studies involving more than 1,500 patients have consistently demonstrated the efficacy and tolerability of CCH in the treatment of PD. CCH significantly decreases penile curvature and plaque consistency, as well as improves quality of life. Post-approval studies continue to demonstrate the efficacy of CCH despite broader inclusion criteria for treatment, such as the case with acute phase disease and atypical plaque deformities (i.e., ventral plaques, hourglass narrowing). CCH continues to be the gold standard for non-surgical management of stable phase PD, in the absence of strong evidence supporting oral therapy agents and ongoing evaluation of extracorporeal shockwave therapy. However, recent studies are beginning to provide precedent for the use of CCH in the management of acute phase and atypical PD.

A prospective, randomized, single - blind study comparing intraplaque injection of thiocolchicine and verapamil in Peyronie's Disease: a pilot study

ABSTRACT Objectives: To compare the response to tiocolchicine and verapamil injection in the plaque of patients with Peyronie's disease. Materials and Methods: Prospective, single-blind, randomized study, selecting patients who have presented Peyronie's disease for less than 18 months. Thiocolchicine 4mg or verapamil 5mg were given in 7 injections (once a week). Patients who had received any treatment for Peyronie's disease in the past three months were excluded. The parameters used were the International Index of Erectile Function (IIEF-5) score, analysis of the curvature on pharmaco-induced erections and size of the plaque by ultrasonography. Results: Twenty-five patients were randomized, 13 received thiocolchicine and 12 were treated with verapamil. Both groups were statistically similar. The mean curvature was 46.7° and 36.2° before and after thiocolchicine, respectively (p=0.019) and 50.4° and 42.08° before and after verapamil, respectively (p=0.012). The curvature improved in 69% of patients treated with thiocolchicine and in 66% of those who received verapamil. Regarding sexual function, there was an increase in the IIEF-5 from 16.69 to 20.85 (p=0.23) in the thiocolchicine group. In the verapamil group the IIEF-5 score dropped from 17.50 to 16.25 (p=0.58). In the thiocolchicine group, the plaque was reduced in 61% of patients. In the verapamil group, 8% presented decreased plaque size. No adverse event was associated to thiocolchicine. Conclusion: The use of thiocolchicine in Peyronie's disease demonstrated improvement on penile curvature and reduction in plaque size. Thiocolchicine presented similar results to verapamil in curvature assessment. No significant side effects were observed with the use of tiocolchicine.

The Outcome of Multiple Slit on Plaque with Plication Technique for the Treatment of Peyronie's Disease

PURPOSE: To evaluate the postoperative outcome of the multiple slit on plaque plication technique for the treatment of Peyronie's disease. MATERIALS AND METHODS: We retrospectively evaluated 22 patients who underwent plaque incision with penile plication for the surgical treatment of Peyronie's disease, who had failed medical treatment between 2009 and 2014. Patients were grouped by preoperative degree of penile curvature into Group I: mild (n=5, 22.7%), Group II: moderate (n=11, 50.0%), and Group III: severe (n=6, 27.3%). After a thorough review of the medical records, we evaluated (a) the correction of the curvature; (b) sexual function; and (c) any penile shortening or other complications. RESULTS: The mean postoperative follow-up period was 39 months. Complete correction of the curvature was attained in 21 patients (95.5%). As an inevitable complication, minimal penile shortening (21). The most frequent complication was subcutaneous penile edema in three patients (13.6%), which was resolved within about 3 months following surgery. CONCLUSIONS: As a modified technique, multiple slit on plaque with plication is a simple, minimally-invasive and effective technique for correcting penile curvature regardless of curvature severity. The degree of penile curvature does not significantly predict the amount of penile length loss.

The Efficacy of Medical Treatment of Peyronie's Disease: Potassium Para-Aminobenzoate Monotherapy vs. Combination Therapy with Tamoxifen, L-Carnitine, and Phosphodiesterase Type 5 Inhibitor

PURPOSE: This study was designed to evaluate the efficacy of medical treatment of Peyronie's disease. MATERIALS AND METHODS: A total of 109 patients with Peyronie's disease who had been treated from January 2011 to December 2014 were retrospectively reviewed in this study. Forty-four patients (Group 1) were treated with 12 mg of potassium para-aminobenzoate daily. Sixty-five patients (Group 2) were treated with combination therapy: tamoxifen (20 mg) and acetyl-L-carnitine (300 mg) twice daily in addition to a phosphodiesterase type 5 inhibitor. Ability to perform sexual intercourse, pain during erection, size of plaque, and penile curvature angle were assessed. RESULTS: In Group 1, 30 of 44 patients (68.2%) discontinued treatment within 12 weeks, while 5 patients (7.7%) in Group 2 discontinued treatment. Pain during erection and plaque size were improved in both groups but showed no statistical difference due to the high dropout rate in Group 1. In both groups, penile curvature was improved, but demonstrated no statistical difference between the treatment groups. However, combination therapy demonstrated a better response rate in patients whose penile curvature angle was less than 30° (44.4% vs. 79.1%, p=0.048). The rate of successful sexual intercourse was significantly higher in Group 2 (42.8% vs. 78.3%, p=0.034). The number of patients who underwent surgical correction despite medical treatment was significantly higher in Group 1 (35.7% vs. 13.3%, p=0.048). CONCLUSIONS: Early medical combination therapy in Peyronie's disease may present better results in patients whose curvature angle is less than 30°.

Nonsurgical Interventions for Peyronie's Disease: Update as of 2016

Peyronie's disease (PD) is a debilitating condition of the penis that leads to significant pain, erectile dysfunction, and emotional distress in men. PD is likely underreported due to lack of knowledge of the disease and the absence of well-established available treatments. Surgical treatment can lead to sustained improvements, but is often associated with penile shortening and places the patient at risk for perioperative morbidity. Nonsurgical management has been studied for several years as an alternative to surgery for men with PD. Currently, much of the data on nonsurgical management is conflicting, with only one treatment that has been recently approved by the US Food and Drug Administration. Significant effort has been devoted to advancing non-surgical treatments for PD that can be implemented outside of the operating room. This review aims to describe the research behind current nonsurgical therapies for PD and to highlight the recent advances that have been made within the last three years.

Partial Priapism Treated with Pentoxifylline

ABSTRACTMain findings:A 26-year-old man suffering from partial priapism was successfully treated with a regimen including pentoxifylline, a nonspecific phosphodiesterase inhibitor that is often used to conservatively treat Peyronie's disease.Case hypothesis:Partial priapism is an extremely rare urological condition that is characterized by thrombosis within the proximal segment of a single corpus cavernosum. There have only been 36 reported cases to date. Although several factors have been associated with this unusual disorder, such as trauma or bicycle riding, the etiology is still not completely understood. Treatment is usually conservative and consists of a non-steroidal anti-inflammatory and anti-thrombotic.Promising future implications:This case report supports the utilization of pentoxifylline in patients with partial priapism due to its anti-fibrogenic and anti-thrombotic properties.
