INTRODUCTION: Implantation of a penile prosthesis in cases of neglected or resistant ischemic priapism, or delayed re-implantation following prosthesis infection and extraction, is usually a difficult and risky procedure due to fibrosis of the corpora cavernosa. Among the common complications are perforation of the urethra, tunica albuginea, and infection. The complications are usually due to the use of blind force against resistance. AIM: We propose the techniques of Trans-Corporeal Resection and Optical Corporotomy as adjuvant measures for excavating the fibrosed corpora cavernosa under vision, without the use of force against resistance. METHODS: Six patients with diffuse fibrosis of the corpora cavernosa were operated on. The instruments and technique are the same as for optical urethrotomy and transurethral resection. Optical Corporotomy was started with, where the corpora are incised from within. After establishment of a satisfactory passage, Trans-Corporeal Resection followed to scrape the fibrous tissue. Implantation of penile prosthesis was completed as usual. The procedure was performed through 1.5 cm incision in the tunica albuginea. MAIN OUTCOME MEASURES: Length, girth, and straightness in the erect position, as well as the incidence of complications. RESULTS: Operative time was an average of 90 minutes. No difficulty was encountered during the procedure. No complications were noted through 1 year of follow-up. CONCLUSION: Optical Corporotomy and Trans-Corporeal Resection allow for force-free, visually monitored excavation of the fibrosed corpora cavernosa, aiming at safer penile prosthesis implantation.

OBJECTIVE: Radical prostatectomy is the most effective treatment for localized prostate cancer. With increasing use of minimally invasive treatment methods, clinical outcomes are becoming important assessment tools to compare one option to another. Perineal prostatectomy is modified to incorporate contemporary surgical ideas, including preservation of cavernosal nerve bundles, sphincteric urethra at the prostatic apex, and the bladder neck. METHODS: Objective parameters and physician-reported clinical outcomes are collected prospectively on 704 consecutive patients undergoing radical perineal prostatectomy (RPP) by one surgeon. The technique described herein is the current state of evolution of RPP. The enclosed digital video is edited from two recent nerve-sparing RPPs. RESULTS: Freedom from prostate-specific antigen (PSA) detectability by stage is 94.5%, 80.0%, and 81.5% for organ-confined, specimen-confined, and margin-positive disease with actual 5-yr follow-up. Margins are positive in 18% of cases. By 1, 3, 6 mo and 1 yr, 52%, 71%, 85%, and 94% of the men are free from using pads. Although >97% of nerve-spared patients have spontaneous erections, >80% can penetrate to complete intercourse. CONCLUSIONS: This method of prostatectomy is able to achieve complete cancer resection while preserving urinary and sexual function in the majority of men presenting with clinically localized prostate cancer. The simplicity and minimally invasive nature of this procedure contribute to a short recovery and low overall cost of therapy. The anatomic RPP is a cost-efficient, outcome-effective minimally invasive method of treating men with localized prostate cancer.
