Abstract:
Objective:To investigate the effect of total anatomical reconstruction (TAR) during robot-assisted radical prostatectomy (RARP) .Methods:The clinical data of 99 patients with RARP performed by a single doctor in our hospital from January 2018 to January 2021 were analyzed retrospectively.There were 38 patients in the TAR+ vesicourethral anastomosis (VUA) group and 61 patients in the VUA group. There were no significant differences between the two groups in the age of patients [ 65.5 (60.8, 71.0) years vs. 66.0 (61.5, 69.0) years], body mass index[ (24.92±2.65) kg/m 2 vs. (25.51±2.80) kg/m 2], prostate volume [28.13 (25.21, 36.53) ml vs. 26.33 (19.75, 47.84) ml], PSA [15.67 (9.02, 31.49) ng/ml vs. 14.58 (9.23, 30.06) ng/ml], neoadjuvant therapy [50.0% (19/38) vs. 63.9% (39/61)], Gleason score (6/7/8/9-10 scores: 8/16/5/9 cases vs. 16/25/9/11 cases) and clinical T stage (T 1/T 2/T 3 stage: 4/29/5 cases vs. 3/53/5 cases)(all P>0.05). The TAR technique was performed as follows. ①The two layers of posterior reconstruction involved the residual Denonvilliers fascia, the striated sphincter and medial dorsal raphe (MDR), and the vesicoprostatic muscle (VPM), the fascia which was 1-2 cm from the cranial side of the bladder neck and MDR. ②The one layer of anterior reconstruction involved detrusor apron, tissues around the urethra and the visceral and parietal layers of the endoplevic fascia. The VUA technique was suturing the bladder neck and urethra consecutively. Perioperative indexes were compared between the two groups. Results:All 99 operations were successfully completed. There were no statistically significant differences between the TAR+ VUA and VUA groups in operation time [ (174.16±47.21) min vs. (188.70±45.39) min], blood loss [ 50 (50, 100) ml vs. 100 (50, 100) ml], incidence of postoperative complications [10.5% (4/38) vs. 14.8% (9/61)], phathological T stage [pT 2/pT 3~4 stage: 25/12 cases vs. 42/19 cases, P=0.895], and the time of indwelling catheter [ 21.0 (19.0, 21.0) d vs. 21.0 (21.0, 21.0) d] (all P>0.05). The difference in postoperative length of stay between the two groups was statistically significant[6.0 (5.0, 6.0) d vs. 7.0 (6.0, 7.5)d, P<0.001]. Follow-up was performed for 1 year after surgery. The recovery rate of urinary continence 3 months after surgery in TAR+ VUA and VUA groups were 86.8% (33/38) vs. 65.6% (40/61), which were statistically significant( P=0.019). There were no significant differences between TAR+ VUA and VUA groups in recovery rate of urinary continence 1 months after surgery [47.4% (18/38) vs. 45.9% (28/61)], 6 months after surgery [94.7% (36/38) vs. 85.2% (52/61)], and 12 months after surgery [94.7% (36/38) vs. 93.4% (57/61)] (all P>0.05). Conclusions:TAR technique has good surgical safety, and can promote recovery of early urinary continence after RARP.
