ABSTRACT
【Objective】 To investigate the safety, feasibility and clinical efficacy of modified anterior robot-assisted laparoscopic radical prostatectomy (RALRP) with preservation of Retzius space. 【Methods】 The clinical data of 10 patients who underwent RALRP using the modified anterior approach to preserve the Retzius space in our hospital during June 2021 and March 2022 were retrospectively analyzed, including the preoperative, intraoperative, postoperative and follow-up data. 【Results】 All operations were successful without conversion to open surgery. The average operation time (robotic arm operation time) was (98.6±47.7) min, blood loss (105.0±57.3) mL, postoperative drainage tube indwelling time (5.3±1.3) d, postoperative urinary catheter indwelling time (7.2±0.8) d, and postoperative hospital stay (9.2±2.2) d. Urinary continence was achieved immediately after removal of the urinary catheter in 6 patients, 2 patients recovered 2 weeks after extubation, and 2 patients recovered 3 months after extubation. Postoperative pathology showed pT2a stage in 1 case, pT2b stage in 2 cases, and pT2c stage in 7 cases; Gleason score was 6-7 points; all postoperative resection margins were negative. During the follow-up of 3-12 months, no tumor recurrence was observed, and no patient was readmitted due to surgical complications. 【Conclusion】 RALRP with modified anterior approach to preserve the Retzius space is safe and feasible, with no serious complications during and after surgery, and the early postoperative urinary continence effect is comparable to that of the posterior approach.
