Curative effects of anatomic reconstruction of periurethral structure in robotic assisted laparoscopic radical prostatectomy / 中华泌尿外科杂志

ABSTRACT

Objective To investigate the outcome of patients underwent anatomic periurethral reconstruction during robotic assisted laparoscopic radical prostatectomy (RARP).Methods During August 2016 to May 2018,anatomic periurethral reconstruction was performed during RARP in 58 consecutive patients.The control group consists of another 50 patients had no anatomic periurethral reconstruction procedure during RARP.Perioperative data of these patients were collected retrospectively,including operation time,anastomosis timeintraoperative blood loss,duration of indwelling catheter,length of hospital stay,complications,postoperative pathology,and continence outcome at 1,3,6,12 months after surgery.Results All cases were successfully performed without conversion to open or laparoscopic surgery.There were no major intraoperative or postoperative complications.Operative time and anastomosis time was (145.3 ± 12.3)mins and (31.6 ± 8.2)mins in reconstruction group comparing to (122.4 ± 11.4)mins and (21.2 ± 4.4) in control group (both P ＜ 0.05).Duration of indwelling catheter was (7.0 ± 0.5) days in reconstruction group and (11.0 ± 0.6) days in control group (P ＜ 0.05).In reconstruction group,estimated blood loss was (108.1 ± 8.3) ml,duration of drainage tube was (3.0 ± 1.2) d,postoperative hospital stay was (8.0 ± 1.1) d,failure of leak test in 1 case,and postoperative complications in 4 cases (6.9％),comparing to (103.3 ± 10.4) ml,(4.0 ± 1.6) d,(10.0 ± 1.5) d,3 cases and 4 cases (8.0％) in control group with no significant difference (all P ＞ 0.05).Postoperative pathology confirmed 53 T2a-T2b diseases and 5 pT2c diseases in reconstruction group,in comparison with 46 T2a-T2b and 4 pT2c diseases in nonreconstruction group (P ＞ 0.05).There were 19 and 15 cases with a final Gleason score of 6,30 and 27 cases with Gleason 7,9 and 10 cases with Gleason 8,in reconstruction group and non-reconstruction group respectively(all P ＞ 0.05).There was no significant difference between the two groups regarding incidence of positive surgical margins (3 in reconstruction group and 2 in control group,P ＞ 0.05).The percentage of patients maintain continence in reconstruction group and non-reconstruction groupat 1 month [84.5 ％ (49/58) and 70.0％ (35/50)],at 3 months [89.7％ (52/58) and 78.0％ (39/50)],at 6 months [91.3 ％ (53/58)and 86.0％ (43/50)] and 1 year after surgery [100.0％ (58/58) and 96.0％ (48/50)].Reconstruction group showed better continence outcome at 1 and 3 month (P ＜ 0.05),with no statistical differences at 6 month and 1 year.The IPSS 1 year after surgery was 10.4 ± 1.6 and 12.1 ± 1.3,with anastomotic stricture in 0 and 2(4％) patients in reconstruction group and control group,respectively (both P ＞ 0.05).Conclusion Anatomic reconstruction of periurethral structure during RARP is safe and feasible with reduced duration of indwelling catheter and better continence outcome.
