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.
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.
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.
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.
根治性前列腺切除术是局限性前列腺癌最有效的治疗方法。随着微创治疗方法的使用日益增加,临床结果正成为比较不同治疗方案的重要评估工具。会阴前列腺切除术已得到改良,纳入了当代外科理念,包括保留海绵体神经束、前列腺尖部的尿道括约肌以及膀胱颈。
前瞻性收集了由一名外科医生连续实施的704例会阴根治性前列腺切除术(RPP)患者的客观参数和医生报告的临床结果。本文所述技术是RPP的当前发展状态。随附的数字视频剪辑自最近两例保留神经的RPP手术。
在实际5年随访中,器官局限性、标本局限性和切缘阳性疾病患者的前列腺特异性抗原(PSA)不可检测率分别为94.5%、80.0%和81.5%。18%的病例切缘阳性。在术后1个月、3个月、6个月和1年时,分别有52%、71%、85%和94%的男性不再使用尿垫。虽然>97%的保留神经患者有自发勃起,但>80%能够进行到完全性交。
这种前列腺切除术方法能够在大多数临床局限性前列腺癌男性患者中实现癌症的完全切除,同时保留泌尿和性功能。该手术的简单性和微创性有助于缩短恢复时间和降低总体治疗成本。解剖性RPP是一种治疗局限性前列腺癌男性患者的经济高效、疗效显著的微创方法。
