(UroToday.com) This was a special plenary held by two esteemed urologists, Dr. Jihad Kaouk and Dr. Ryan Nelson, who gave a talk on extraperitoneal and transvesical approaches to single-port robotic radical prostatectomy.
Part One- Single Port Robotic Radical Prostatectomy: Extraperitoneal and Transvesical Approaches
Up first, Dr. Kaouk, delivered a presentation on the advancements and benefits of Single Port (SP) Robotic Radical Prostatectomy, specifically focusing on extraperitoneal and transvesical approaches.
His talk emphasized the importance of regionalizing surgery using a low-profile robotic system that offers excellent access to challenging anatomical areas, contrasting it with the more invasive multiport systems that traverse the entire abdominal cavity.
Reflecting on his journey, Dr. Kaouk shared how he transitioned from a multiport surgeon with over 20 years of experience to primarily utilizing the single-port transvesical approach.
He underscored the importance of replicability and teachability in surgical innovations, emphasizing that “surgery done by the few does not have much value.” Dr. Kaouk strongly advocated for single-port surgery, highlighting its versatility as a customizable surgical approach. He recommended the transvesical approach as the default choice, particularly for patients with a hostile abdomen or those requiring concurrent management of bladder stones and diverticula, as well as for prostate volumes under 80-100 grams. The extraperitoneal approach, he suggested, is best suited for obese patients or when extended lymph node dissections are necessary. For patients with a history of bladder trauma or previous bladder surgery, Dr. Kaouk advised using the transperineal approach.
Through a video demonstration, Dr. Kaouk highlighted the benefits of the single-port approach in both extraperitoneal and transvesical techniques, such as improved vision, less invasiveness, and the ability to target specific areas with ease. The transvesical single-port technique also allowed for precise nerve sparing, resulting in an 80% rate of post-surgical erectile function recovery, though he noted that further data is needed to substantiate this; more surgical data regarding the transvesical approach’s post-operative outcomes are in the image below.
In comparing multiport and single-port outcomes, Dr. Kaouk found no significant differences in biochemical recurrence (BCR)-free survival in respect to oncological outcome, but single-port approaches consistently outperformed multiport surgeries in terms of patient comfort.
Single port surgery resulted in shorter hospital stays, reduced opioid use, quicker removal of Foley catheters, and a remarkable 40% of patients experiencing immediate urinary continence post-surgery.
Additionally, single-port patients showed a lower incidence of post-operative hernias due to the minimally invasive nature of the procedure.
The transvesical single-port approach, with its direct percutaneous access into the bladder, proved especially valuable for patients with intra-abdominal adhesions or those who have a hostile abdomen or had previously undergone aborted radical prostatectomies. The approach was so minimally invasive that some patients could even remain awake during surgery.
Dr. Kaouk concluded by emphasizing the multidimensional value of single-port robotic surgery. For patients, it allows for customizable surgeries, quicker recovery at home, minimal narcotic use, favorable cosmetic outcomes, and excellent long-term results. For surgeons, it offers better ergonomics, opportunities to master various approaches, and the use of state-of-the-art technology. For healthcare systems, single-port robotic surgery improves outpatient care, increases patient flow, and represents cutting-edge innovation.
The subsequent talk was presented Dr. Nelson, who provided deeper insights into the ongoing discussion of single port extravesical versus transvesical prostatectomy. Building on Dr. Kaouk’s earlier presentation, Dr. Nelson reviewed the advantages and disadvantages of each approach.
To illustrate his points, he presented a side-by-side video comparison of the two methods. The transvesical approach, he noted, offers easier access and greater preservation of local anatomy for subjects under 80 grams but is constrained by limited space within the bladder. This restricted workspace also makes suturing more challenging. In contrast, the extravesical approach allows for easier instrument rotation, which can simplify certain aspects of the procedure.
However, Dr. Nelson highlighted a significant drawback of the transvesical approach: a higher incidence of erectile dysfunction compared to the extravesical method. This key distinction emphasizes the need for careful consideration of each patient’s circumstances when choosing the surgical approach.
The talks by Drs. Kaouk and Nelson exemplified how single-port robotic surgery is advancing patient care and transforming surgical practice. Dr. Kaouk demonstrated that single-port robotic surgery is not only advancing patient care but also transforming surgical practice and healthcare delivery while Dr. Nelson illustrating how choosing the appropriate technique can significantly impact patient outcomes and surgical efficacy.
