Background:
The introduction of robotic surgical platforms holds the potential to accelerate the evolution of natural orifice transluminal endoscopic surgery (NOTES). This study aimed to evaluate the feasibility and safety of robotic transvaginal hybrid NOTES nephrectomy based on a retrospective case series from our hospital.
Methods:
From August 2019 to August 2024, a total of 23 patients underwent robotic transvaginal hybrid NOTES nephrectomy at our institution. All procedures were performed using the Da Vinci Xi robotic system. Two 8-mm robotic ports were placed at the margins of the umbilicus. Another 8-mm robotic scope port was placed transvaginally via the posterior fornix. An assistant 12-mm port was placed at the suprapubic midline. After dissection of the kidney, it was removed transvaginally. All data referring to patients were recorded and analyzed. The cosmetic result was evaluated according to the Patient Scar Assessment Questionnaire and Scoring System (PSAQ). Sexual function was investigated by administering the Female Sexual Function Index (FSFI).
Results:
All 23 robotic transvaginal hybrid NOTES nephrectomy procedures were successfully completed without conversion to open surgery. The mean operative time was 188 min (range 120-330 min). The mean estimated blood loss was 216 ml (range 30-800 ml). The mean Visual Analog Scale (VAS) score at 24 h postoperatively was 2.4 (range 2-4), indicating minimal pain. The excellent cosmetic results were confirmed by the PSAQ score. Nineteen patients completed the FSFI questionnaire, and analysis did not show significant differences before and after surgery. One patient achieved spontaneous pregnancy 3 years after surgery and delivered successfully via the vaginal route.
Conclusions:
Robotic transvaginal hybrid NOTES nephrectomy is feasible, safe, and effective in properly selected patients, providing minimal postoperative pain and excellent cosmetic results.
