Objectives: To analyze initial treatment results for robot-assisted laparoscopic radical prostatectomy (RALP).
Subjects: 153 patients who underwent RALP in our hospital from June 2014 to December 2017.
Results: We performed nerve-sparing surgery in 108, lymph node dissection in 81, and procedures to prevent inguinal hernias in all patients. 94.8% patients were released from our hospital in postoperative days 7. The median hemorrhage volume was 65 cc. Although there were two cases of postoperative hemorrhage, there were no cases of urinary retention, symptomatic lymphoid cyst, or rectal, ureteral, or obturator nerve injury. However, one patients needed antibiotics therapy for peritonitis caused by small intestine damage. There were five cases of postoperative inguinal hernias. The positive margin rate was pT2;18.5%, pT3; 58.8%, respectively. However, recent positive margin rates are lower. The median number of lymph nodes removed was 16 and metastasis was observed in 3 cases. The overall 12- and 24-months PSA-failure-free survival rates were 89.9 and 83.6%, respectively. Positive margin, Gleason group, and initial PSA level were significantly associated with PSA-failure. The 1-, 3-, 6-, 9-, 12-, 24-month postoperative continence (0-1 pad per 24hr) rates were 56%, 86%, 93%, 95%, 95%, and 93%. Nerve-sparing surgery and small prostate were independent predictive factors for good urinary continence.
Conclusion: We conducted RALP safely, and our results are mostly consistent with those of contemporary series. On the other hand, we need to continue to accumulate experience safely in order to improve outcomes of cases requiring extensive resection and to train operators.
