3D laparoscopic prostatectomy: results of multicentre study

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Three-dimensional laparoscopic prostatectomy (3D LRP) is an emerging technique for robot-assisted radical prostatectomy.
• Limited data exists on the outcomes of 3D LRP compared to established methods like two-dimensional LRP and RALP.

Purpose of the Study:

• To evaluate the perioperative and short-term outcomes of 3D LRP.
• To compare 3D LRP results with existing literature on RALP.

Main Methods:

• A multicentre study involving 496 men with prostate cancer undergoing 3D LRP.
• Data collected included patient demographics, preoperative PSA, pathological details, operative parameters, and complications (Clavien-Dindo classification).
• Postoperative outcomes assessed included PSA levels and urinary continence at 3 and 12 months.

Main Results:

• High rates of biochemical recurrence control: 90.2% at 3 months and 91.4% at 12 months with PSA <0.2 ng/ml.
• Good functional outcomes: 77.1% continence at 3 months and 87.7% at 12 months (dry or 1 pad/day).
• Median operative time was 137 minutes with a median blood loss of 200 ml; major complications (Clavien-Dindo IIIa/IIIb) were 6.9% and 1.6% respectively.

Conclusions:

• 3D LRP demonstrates favorable short-term oncological and functional results.
• The outcomes of 3D LRP appear comparable to those reported for RALP in existing studies.
• 3D LRP represents a viable and potentially cost-effective option for robot-assisted prostatectomy.
