Comparative Analysis of Cold Versus Thermal Dissection in Nerve-Sparing Robot-Assisted Radical Prostatectomy

TL;DR

Using cold dissection during robotic prostate surgery helps men recover urinary control and sexual function faster than traditional methods.

Contribution

This study provides evidence that cold dissection improves early functional recovery in nerve-sparing prostatectomy.

Findings

Cold dissection improved urinary continence at 15 and 30 days post-surgery.

Erectile function recovery was better in the cold dissection group up to six months after surgery.

Age and preoperative IIEF-5 scores were key predictors of recovery outcomes.

Abstract

Robotic prostate surgery can cure prostate cancer, but many men experience urinary incontinence and erectile dysfunction afterward. This study investigated whether using a “cold dissection” technique during nerve-sparing robotic prostatectomy leads to better early recovery of urinary continence and sexual function. The researchers compared two groups of patients: one treated with cold dissection and the other with traditional thermal dissection. Patients treated with cold dissection had better urinary continence rates within the first 15 and 30 days and improved erectile function up to six months after surgery. This approach may help men recover faster and maintain a better quality of life after prostate cancer surgery.

Background: Cold dissection (CD) during nerve-sparing robot-assisted radical prostatectomy (nsRARP) in patients with prostate cancer has been proposed to improve functional outcomes by reducing the thermal damage to neurovascular bundles (NVBs). This study compares the impact of CD versus thermal dissection (TD) on postoperative early continence and erectile function recovery. Methods: A prospective comparative analysis was conducted on patients undergoing nsRARP, comparing CD and TD techniques. Continence was assessed at 15, 30, and 90 days, while erectile function was evaluated at 30, 90, and 180 days using IIEF-5 scores. Logistic and linear regression analyses were performed to identify predictors of functional recovery. Results: CD significantly improved early continence at 15 and 30 days (p < 0.05), although the difference diminished by 90 days. Erectile function recovery was consistently higher in the CD group at all time points (p < 0.01). Age negatively impacted continence and erectile function recovery, while preoperative IIEF-5 scores were strong predictors of erectile function. Prostate volume, BMI, and metabolic syndrome showed no significant influence on outcomes. Conclusions: CD enhances early continence and erectile function recovery following nsRARP by preserving NVBs and minimizing thermal damage. This technique offers a valuable approach to improving patient functional outcomes. Further studies are required to validate its long-term benefits.
