Use of a lyophilized bovine pericardium graft to repair tunical defect in patients with Peyronie's disease: experience in a clinical setting.

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.

Comparison of the patient and partner satisfaction with 700CX and Titan penile prostheses.

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.

Infectious complications after transrectal ultrasound-guided prostatic biopsy. Analysis of our experience.

OBJECTIVES: To establish the rate of infectious complications derived from the use of transrectal ultrasound-guided prostate biopsy (TRUS), identify its microbiological profile and related risk factors. METHODS: We designed a prospective non-randomized study in which we enrolled 220 patients undergoing TRUS biopsy at our centre between April and September 2008. The inclusion criteria were: suspicious digital rectal examination, PSA >10 ng/ml, and free/total ratio of PSA is assessed in patients with PSA 4-10 ng/ml. The exclusion criteria were: having an indwelling urinary catheter, the administration of antibiotic treatment in the week before the needle biopsy, manipulation of the urinary tract in the month prior to the needle biopsy, allergy to quinolones and risk of endocarditis, failure to comply with the antibiotic prophylaxis regimen and loss to follow-up. We analyzed the relationship between diabetes, immunodepression, previous UTI or prostatitis and positive prebiopsy urine culture with the appearance of fever, dysuria or bacteriuria following needle biopsy. RESULTS: Mean age was 69.5 years (+/-7.9), mean total PSA 12.7 ng/ml (+/-28.7), mean prostate volume 50.6 cc (+/-29.6) and mean number of cores obtained by needle biopsy 13.5 (+/-1.7). 25% of the patients had dysuria following needle biopsy, 3.2% fever and 4.5% bacteriuria. E.coli was the pathogen most frequently found in pre- and post-biopsy urine cultures. No statistically significant relationship was found between the appearance of dysuria and fever and being diabetic, having immunosuppression, previous UTI or prostatitis, prostate volume and number of cores obtained in the biopsy. Only the existence of a positive pre-biopsy urine culture and biopsy with more than 14 cores proved to have a statistically significant association with the existence of bacteriuria following biopsy, p=0.007 and p= 0.018, respectively. CONCLUSIONS: Our rate of infectious complications was similar to that described in other series. The existence of a positive prebiopsy urine culture and obtaining more than 14 cores per biopsy was related, with statistical significance, to the existence of bacteriuria following the biopsy. E.coli was the most frequently isolated pathogen.
