Surgical Experience and Results of Retzius Sparing Robotic Assisted Laparoscopic Radical Prostatectomy: First Report in Thailand
Abstract
Objective: To evaluate the outcomes and safety of the surgical technique Retzius-sparing robot-assisted laparoscopic radical prostatectomy (RS-RALRP), with prostatic cancer; the first report in Thailand.
Material and Methods: The authors conducted a retrospective analysis from the medical records of 100 patients who underwent RS-RALRP by a single surgeon; from 1st January 2021 until 31st May 2023, at Rajavithi Hospital. The authors analyzed demographic data, clinical staging, Gleason grade group, operative time, pathologic staging, positive surgical margin rate; postoperative continence recovery and postoperative complications.
Results: The median age was 71.34±6.84 years: mean total PSA was 17.16±17.55 ng/ml; with the majority in clinical T1 and T2. The mean operative time was 221.7±51.93 minutes, and the mean estimated blood loss was 312.30±264.55 ml. Of all patients, 88% did not require blood transfusion. The complication rate was 8%. The pathologic stages pT2 and pT3 or greater were 62% and 38%, respectively. Positive surgical margins (PSM) pT2 and pT3 were 14.5% and 63.2%. The postoperative continence recovery after RS-RALRP were 83%, 95%, 97%,100% and 100%: at 1, 3, 6, 9 and 12 months postoperatively, respectively.
Conclusion: RS-RALRP has a potential to become the new standard for prostate cancer treatment, with improved early continence and equivalent oncologic efficacy. The limitations of this study are the small number of population, which require prospective multicenter studies.
