Nerve Monitoring During Prostate Surgery: Impact on Functional Outcomes

What is it about?

In this study, the use of the ProPep Nerve Monitoring System during robot-assisted radical prostatectomy (RARP) did not result in better functional outcomes, such as continence rates, in patients who underwent unilateral nerve-sparing (UNS) or non-nerve-sparing (NNS) RARP. The study included 100 patients, with 50 in each group, and followed them for 12 months after the surgery. The continence rate was higher in the intervention group at 6 months, but there were no statistically significant differences in any of the remaining outcomes. The study suggests that larger studies are needed to explore if ProPep can reduce the time to continence after RARP.

Why is it important?

The study is important because it investigates the use of the ProPep Nerve Monitoring System during robot-assisted radical prostatectomy (RARP) to identify and preserve somatic nerve fibers that innervate the external sphincter, which may play a pivotal role in developing urinary incontinence (UI) after the surgery. By preserving these nerve fibers, the researchers aimed to mitigate UI and improve erectile function. The study provides valuable insights into the safety and efficacy of the ProPep system and may help inform future treatments for patients undergoing RARP. Key Takeaways: 1. The study randomized 100 men undergoing unilateral nerve-sparing (UNS) or non-nerve-sparing (NNS) RARP to the ProPep Nerve Monitoring System during RARP (intervention) or standard of care RARP (control). 2. Intraoperative nerve monitoring did not result in better functional outcomes following UNS or NNS RARP. 3. The continence rate was higher in the intervention group at 6 months, but the difference did not reach statistical significance at 12 months. 4. The intervention was safe and did not significantly increase blood loss or surgical time. 5. Further studies are needed to explore if the intervention may facilitate an earlier return to continence.
