RADICAL RETROPUBLIC PROSTATECTOMY - 03/09/11
Resumen |
Radical retropubic prostatectomy originally was described by Millin in 1945.6 Many urologists embraced the retropubic approach because they were more familiar with retropubic anatomy. An advantage of the retropubic versus the perineal approach was the ability to perform a simultaneous staging pelvic lymphadenectomy.13 Historically, significant bleeding often was encountered while attempting to control the dorsal venous complex during radical retropubic prostatectomy. One of the advantages of the perineal approach was less intraoperative bleeding because it was not necessary to ligate the dorsal venous complex.13
Development of the anatomic nerve-sparing radical retropubic prostatectomy by Walsh required a bloodless operative field and a thorough knowledge of pelvic anatomy. Reiner and Walsh8 described the anatomy of the dorsal venous complex and a surgical technique for ligating this complex in 1977, which greatly diminished the bleeding associated with radical retropubic prostatectomy. Anatomic studies in the early 1980s demonstrated the precise relationship of the cavernous nerves relative to the prostate and other pelvic structures in the human fetus11 and adult.5
These landmark anatomic studies set the stage for Walsh's description of the anatomic nerve-sparing radical retropubic prostatectomy.11 One of the major advantages of the anatomic nerve-sparing retropubic approach is the ability to preserve the cavernous nerves and erectile function in the overwhelming majority of men undergoing prostatectomy for the cure of clinically localized prostate cancer. An equally important advantage is the description of an anatomic surgical technique that greatly diminishes technical complications.
Owing to the widespread acceptance of prostate-specific antigen (PSA) screening in the early 1990s,1, 2 there has been a significant increase in the detection of clinically localized prostate cancer. Currently, radical prostatectomy represents one of the most common surgical procedures performed by urologists in community practice. The increasing experience of individual surgeons coupled with the anatomic nerve-sparing technique has diminished intraoperative technical complications greatly while improving outcomes related to quality of life.3, 14, 15
A new standard now exists for radical retropubic prostatectomy regarding intraoperative and postoperative complications.10 In the hands of experts, the surgical procedure is performed in less than 2 hours; the hospital stay is approximately 2 days; the operative mortality rate is typically less than 0.2%; technical complications, including rectal injury, urethral injury, and significant vascular injury, are less than 1%; transfusion rates are less than 10%; significant incontinence is exceedingly rare; and most potent men retain their erectile function.
Since 1986, the author has performed more than 1600 radical retropubic prostatectomies. The author is fortunate to have been the student of Patrick C. Walsh, MD, the developer and master of this operation. The author has not only participated in the evolution of the surgical technique but has witnessed Walsh's passion and commitment to improving the operative procedure. Although the framework of prostatectomy as performed by the author and Walsh is similar, the author's unique technical maneuvers are illustrated in this article. The author is grateful to medical illustrator Tori Guy, who worked diligently to transcribe events in the operating room into the illustrations presented in this manuscript.
