Many different materials are available for grafting during surgery for Peyronie's disease (PD). To study the outcomes associated with the use of a lyophilized bovine pericardium graft (Peri-Guard®) to repair tunical defects in patients with PD, descriptive study of 43 patients with disabling penile curvature was performed. Curvature was measured before and after the intervention using a standardized procedure. Surgical technique was plaque excision and grafting of the tunical defect carried out by a single surgeon. A lyophilized bovine pericardium patch was used for grafting. We measured the change in penile curvature and length, the ability to perform successful sexual intercourse without further pharmacological or surgical treatment, and the satisfaction with treatment. Follow-up data were available for a total of 41 patients. Median age was 50 years (IQR 48-52); mean follow-up time was 14 ± 6 months. Complete penile straightening was achieved in 33 patients (80.5%) and five patients (12.2%) had curvature under 20°. Three months after surgery and stretching therapy, mean (s.d.) flaccid penile length increased from 11.2 ± 2.8 cm to 12.1 ± 2.9 cm (P = 0.062). Seventy-five percentage of patients reported being able to achieve successful intercourse without further treatment. Eighty-five percentage of patients reported to be satisfied with the treatment. There was no evidence of tissue rejection or infection, and only four patients suffered an adverse event. Plaque excision and grafting of the tunical defect with lyophilized bovine pericardium seems to be a safe and effective treatment for patients with PD.

Most widespread three-component penile prosthesis models are 700CX™ and Titan ®. Our purpose is to assess patient and partner satisfaction after the first implant. This is a multicenter, retrospective, nonrandomized study in which all patients who met the inclusion criteria between 2009 and 2013 were included. In total, 248 patients agreed to participate. To evaluate patient satisfaction, a validated but modified 11-question questionnaire was completed (EDiTS); and a nonvalidated two-item questionnaire was given to the partner. Statistical analysis used an ordinal logistic regression model. Two hundred and forty-eight patients (194 with 700CX™ vs 54 with Titan®) and 207 couples completed the questionnaire (165 with 700CX™ vs 42 with Titan®). Overall satisfaction was high. Both showed great reliability for sexual intercourse and high compliance with prior expectations. Most patients were able to manage the penile prosthesis correctly within 6 months. Postoperative penile shortening led to some dissatisfaction in 42% and 46% of cases (700CX™ /Titan®). Significant differences were found in three questions of patients' questionnaire. There were more patients satisfied with the 700CX™ (P = 0.0001). No patient with Titan® implant took longer than 6 months to optimal management. Only 4% of patients with 700CX™ implant were dissatisfied with the deflation, in contrast to 24% with the Titan® (P = 0.0031). Of the two partners' questions, one showed a statistically significant difference (P = 0.0026). It seems that group 700CX™ would recommend to re-implant the prosthesis with a greater tendency. The overall satisfaction was very high for both prostheses. The final aspect of the erected and flaccid penis was satisfactory, but both groups showed significant discontent with its final size. Partners' overall satisfaction was high.

Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been associated with multiple entities and several types of cancers. They can be assumed as markers of inflammatory imbalance. The objective of this study is to evaluate the NLR and PLR in Peyronie's disease (PD) and to establish a comparison of its values in the acute and chronic stages. We recruited patients with PD from March 2018 to March 2019. The patients enrolled underwent medical and sexual history as well as a physical examination. The values of blood count of each patient were collected both in the acute and chronic stages. Wilcoxon test was used to compare the acute and chronic stage ratios. Kruskal-Wallis test was carried out to evaluate the impact of treatments on the ratios. To identify cutoff values, we used sensibility and specificity tables and receiver operating characteristic (ROC) curves. A total of 120 patients were enrolled. Their mean age was 55.85 (range: 18-77) years and the mean penile curvature was 48.43° (range: 10°-100°). In the acute stage, the mean NLR was 2.35 and the mean PLR was 111.22. These ratios, in the chronic stage, were 1.57 and 100.00, respectively. Statistically significant differences between acute and stable stages for both indices were found (NLR: P< 0.0001; PLR: P= 0.0202). The optimal cutoff for classification in acute or stable stage was 2 for NLR and 102 for PLR. According to our results, with an ordinary blood count, we could have important indications regarding the disease stage of the patient, and consequently on the most appropriate type of therapy to choose.
