There is need for prospective, clinical trials to define safe and effective management strategies for patients with low-flow, high-flow or recurrent priapism.

Introduction Peyronie's disease is a sexual medicine condition that may adversely affect male sexual function. Aim To provide expert opinions/recommendations concerning state-of-the-art knowledge for the pathophysiology, diagnosis and treatment of Peyronie's disease. Methods An International Consultation in collaboration with the major urology and sexual medicine associations assembled over 200 multidisciplinary experts from 60 countries into 17 committees. Committee members established specific objectives and scopes for various male and female sexual medicine topics. The recommendations concerning state-of-the-art knowledge in the respective sexual medicine topic represent the opinion of experts from five continents developed in a scientific and debate process. Concerning the Peyronnie's disease committee, there were 10 experts from six countries. Main Outcome Measure Expert opinions/recommendations are based on grading of evidence-based medical literature, extensive internal committee discussion over 2 years, public presentation and deliberation. Results Peyronie's disease is characterized by an inflammatory response beneath the tunica albuginea with fibroblast proliferation forming a thickened fibrous plaque that may cause penile pain, penile curvature and erectile dysfunction. Medical treatments have been described but few prospective controlled trials have revealed significant clinical benefits. Surgical treatments (penile plication, Nesbit excision, plaque incision and grafting and penile prosthesis insertion) should be considered after Peyronie's disease has stabilized. Surgical outcome studies reveal that a stable deformity is best corrected with the least postoperative ED by a Nesbit procedure. Plaque incision and grafting should be reserved for men with good erectile function and marked penile shortening although there is a higher prevalence of postoperative ED. Implantation of a penile prosthesis is an excellent option for men with an accompanying erectile deficit. Conclusions Safe and effective treatments for Peyronie's disease examined by prospective, placebo-controlled, multi-institutional clinical trials are needed.

Objective  To investigate whether changes in the structure of the tunica albuginea influence the development of erectile dysfunction. Patients and methods  Biopsy specimens taken from the tunica of 64 patients (both potent and impotent) with and without Peyronie's disease were evaluated. Tissue samples were stained and examined under light and electron microscopy, and the concentration of elastic fibres present in each was measured using computerized image analysis. Results  The concentration of elastic fibres was lower in impotent than in potent patients (P=0.0365) and was also significantly less in patients with Peyronie's disease. Furthermore, the concentration of elastic fibres decreased with age. Electron and light microscopy revealed the presence of distinct alterations in the tunica albuginea in impotent patients and patients with Peyronie's disease that might interfere with function. Conclusion  The decrease in elastic fibre concentration and changes in microscopic features may contribute to erectile dysfunction by impairing the veno‐occlusive function of the tunica albuginea.

Predictive factors that could possibly affect the cure and complication rates of tension-free vaginal tape (TVT) in the treatment of stress urinary incontinence (SUI) were investigated. Seventy-five consecutive patients with urodynamically proven SUI and who had undergone a TVT operation were evaluated according to a follow-up protocol. Median age was 51.2 (33-69). Thirteen (17%) of the patients had had previous anti-incontinence surgery. Sixteen (21%) patients had complained of pure stress and 59 (79%) of mixed incontinence. Valsalva leak point pressure (VLPP) values had been found to be below 60 cmH(2)O in 36 (48%) and over 60 cmH(2)O in 39 (52%) patients, while detrusor overactivity (DO) had been detected in six (8%) patients during urodynamic evaluation. Local, general, and epidural anesthesia had been performed in 43 (57%), 29 (39%), and three (4%) patients, respectively. Univariate analyses were done using Fisher's exact and Chi-square tests. Multivariate analyses were done using logistic regression test to determine predictive factors affecting cure and complication rates. Mean surgical and hospitalization times were 34.7 min (20-70) and 1.2 days (1-5), respectively. Mean follow-up was 21.6 months (6-38). Cure and improvement rates were 89 and 8%, respectively. Thirty-one complications were observed in 27 (36%) patients. Intraoperative bladder perforation and bleeding occurred in three (4%) and two (3%) patients, respectively. Sixty-six (88%) patients voided spontaneously after TVT while nine (12%) performed clean intermittent catheterization (CIC) for a period of time. Seven of nine patients regained the spontaneous voiding ability within 1 month. The tape was cut in two of these retentive patients and one with severe storage lower urinary tract symptoms (LUTS) either unilaterally or bilaterally. On univariate (Fisher's exact test, p =0.018), and multivariate (Logistic regression, p =0.013) analyses, patient age was the only statistically significant parameter affecting the cure rate, which was significantly lower particularly over 55 years of age. No significant factor predicting the complications was detected. TVT is an effective and safe surgical procedure in the treatment of SUI. In this study age was the only significant predictive factor affecting the cure rate while no significant factor predicting the complications was detected. Cure rate was significantly lower in patients over 55 years of age.
