ABSTRACT
Objective To introduce the initial application experience of SUTURE (suture-undertent and underside-reposition-enhancement) technique in robotic-assisted radical prostatectomy and discuss its safety and effectiveness.Methods The surgeon has performed 64 cases of Robotic-assisted radical prostatectomy between November 2016 to April 2017.The mean age was (66.6 ± 1.6) years (53-81 years);median PSA was 15.29 ng/ml(1.41-152.53 ng/ml),tumor stage was T1cN0M0-T3bN0M0.The patients were diagnosed by ultrasound-guide prostate biopsy.The number of cores was 6-15,average Gleason score was 7.3 points (6-10 pionts).ECT and MR were used to assess local stage and bone metastasis.The tPSA and urine recovery (urine pad test) was followed-up regularly.SUTURE technique consists of two parts,control the DVC effectively by retain the puboprostatic ligaments and puboprostatic ligaments reconstruction.Result All cases were successfully completed without complication,the average operation time was 95 min (66-150 min);bleeding (106 ± 15) ml(50-300 ml).All the catheters were released 14 days after surgery.Postoperative pathological staging was pT2aN0-pT3bN1,25 cases of capsule invasion,12 cases with seminal vesicle invasion,37 cases with nerve invasion.Average Gleason score was 7.2 points (6-10 points).The median tPSA detected 4 weeks after surgery was 0.047 ng/ml(0.007-12.050 ng/ml).The follow-up time was 1-6 months.The rate of urine control in 1 month and 3 month were 40.8％ (20/49) and 75.8％ (25/33).Conclusions By using SUTURE technique we can control thedorsal vascular complexstrictly,and complete the puboprostatic ligaments reconstruction by stitch it to the anterior vesicourethral.The SUTRUE is a safe and effective systematic DVC controlling technique,and the early urinary control rate is satisfactory.
