title: [MODIFICATIONS FOR CONTROLLING THE DORSAL VEIN COMPLEX IN ROBOTIC-ASSISTED LAPAROSCOPIC RADICAL PROSTATECTOMY].
abstract: OBJECTIVE
  To investigate a superior method for controlling the dorsal vein complex (DVC) in robotic-assisted laparoscopic radical prostatectomy at Nagakubo hospital.
  
  
  METHODS
  DVC control was altered from suture ligation followed by DVC division (SL group, n = 115) to preceding division followed by suture (PD group, n = 62). Surgical margin status and functional outcomes were investigated.
  
  
  RESULTS
  No notable surgical complications were found in the PD group. Operation time and estimated blood loss were significantly less in the PD group; however, changes to serum hemoglobin before and after surgery showed no significant difference. The rates of positive surgical margin were 26.1% and 11.3% in the SL and PD groups, respectively (p = 0.021). Apical margin positivity was 9.6% and 3.2% in the SL and PD groups, respectively (p = 0.12). Urinary continence outcomes of within one pad/day and pad free in the SL and PD groups until 6 mo after surgery were 93.6% and 89.1% (P = 0.21), and 67.3% and 67.5% (p = 0.96), respectively. Erection recovery within 6 mo was 43.6% and 41.7% in the SL and PD groups (p = 0.91).
  
  
  CONCLUSIONS
  Preceding division followed by suture method decreased apical margin positivity and provided superior cancer control in comparison with suture ligation followed by DVC division, although, it was probably influenced by the learning curve. Functional outcomes were not significantly different with either method.
