This study shows that totally endoscopic extraperitoneal radical prostatectomy is a safe and effective technique for prostate cancer treatment. It offers similar oncological and functional outcomes to traditional laparoscopic methods with reduced complications.

Area of Science:

  • Urology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Transperitoneal laparoscopic radical prostatectomy is a common minimally invasive technique.
  • A totally extraperitoneal retropubic approach was developed to potentially improve upon existing laparoscopic methods.

Purpose of the Study:

  • To report the initial experience and outcomes of 70 patients undergoing a totally endoscopic extraperitoneal retropubic radical prostatectomy.

Main Methods:

  • Seventy patients underwent the endoscopic extraperitoneal radical prostatectomy procedure.
  • Key steps included preperitoneal space preparation, trocar placement, pelvic lymph node dissection, prostate mobilization, and urethrovesical anastomosis.
  • Concomitant hernia defect repair was performed in some cases.

Main Results:

  • No conversions or re-interventions were required, with a mean operative time of 155 minutes.
  • Pathological stages ranged from pT2a to pT4, with positive surgical margins in 6.1% of pT2 and 35.1% of pT3/pT4 tumors.
  • Low morbidity was observed, including penile edema/hematoma, asymptomatic lymphoceles, and transient obturator nerve paralysis.

Conclusions:

  • The preliminary results of endoscopic extraperitoneal radical prostatectomy are promising, demonstrating low operative and perioperative morbidity.
  • This technique achieves efficacy and outcomes comparable to laparoscopic radical prostatectomy.
  • It represents a technical advancement by avoiding intra-abdominal complications and combining benefits of minimally invasive surgery and open retropubic approaches.
