The pannus was retracted away from the midline and we employed our “Rule of 20” which is, using the root of the penis as a visible landmark for robotic port placement. We measured 20 cm from the root of the penis and placed the camera port just under the umbilicus. We then placed the rest of our robotic ports in standardized fashion around the camera port. The “Rule of 20” is an MRI based study which states that if the functional length of the robotic arm is the hypotenuse of a right triangle, the distance between the root of the penis and the membranous urethra is the base of a triangle then the height of the triangle averages out to be approximately 20cm, and we have been using this theory for port placement since the study.

Introduction & Objectives: To describe a novel technique of total vesico-urethral reconstruction, which combines the tactics of previous surgeons, and to compare the outcome of our innovative changes for return to early continence with prostatectomies with no or partial reconstruction of the vesico-urethral junction. Material & Methods: Between 1 January 2005 and 5 June 2007 a cohort of 700 patients undergoing robotic radical prostatectomy were prospectively evaluated. Patients in 2005 (214) served as a control group, they received no additional methods to provide support to the YHVLFRXUHWKUDOMXQFWLRQDVWDQGDUGDQDVWRPRVLVZDVPDGH3DWLHQWVLQ  UHFHLYHG an anterior reconstruction only, to provide additional vesico-urethral anastomotic support. Patients in 2007 (182) received the total reconstructive procedure, which included an anterior reconstruction and posterior reconstruction. Outcome data were collected using standardized health-related quality-of-life measures, which included the Expanded Prostate Cancer Index Composite survey, International Prostate Symptom Score, International Index of Erectile )XQFWLRQDQGWKHQUHYHULᚏHGE\WHOHSKRQHLQWHUYLHZZLWKDVWDQGDUGL]HGTXHVWLRQQDLUH7KH IROORZXSLQWHUYDOVZHUHDQGZHHNV&RQWLQHQFHZDVGHᚏQHGDVQRSDGXVDJH or one small liner used for security purposes only.

TENSION AND ENERGY-FREE ROBOTIC-ASSISTED LAPAROSCOPIC RADICAL PROSTATECTOMY WITH LATERAL DISSECTION DISSECTION OF THE NEUROVASCULAR BUNDLES: 1 YEAR FOLLOW UP

CAN STANDARDIZED FROZEN SECTIONS IN LAPAROSCOPIC EXTRA PERITONEAL PROSTATECTOMY REDUCE THE NUMBER OF POSITIVE MARGINS?

Naspro R., Mattei A., Annino F., Piechaud T., Gaston R. Clinic Saint Augustin, Dept. of Urology, Bordeaux, France Introduction & Objectives: To assess oncological and functional outcomes at one year follow-up after robotic-assisted laparoscopic radical prostatectomy (RALP) with a new lateral approach for the dissection of the neurovascular bundles without tension and any use of electrocautery. Material & Methods: Between April and September 2006, 100 consecutive patients ZLWK RUJDQFRQᚏQHG SURVWDWH FDQFHU DJH \UV 36$ืQJGO *OHDVRQ VFRUHื DQG,,()ุ XQGHUZHQW5$/3E\WKHVDPHVHQLRUVXUJHRQ3UHLQWUDSHULDQGSRVW operative data were recorded. Patients were assessed at the 4 and 12 month followup. Results: RALP was successfully completed in all patients. Neither blood transfusions nor early re-intervention were necessary. One week following catheter removal, complete early urinary continence was achieved in 80% of patients, and spontaneous erections or penile tumescence were reported by 46 patients (46%) without the use of PDE-5 inhibitors. Positive surgical margins were 12.1% in the pT2 group and 29% in the S7JURXS2XWRIWKHVHWHQSDWLHQWVVXEVHTXHQWO\XQGHUZHQWDGMXYDQWUDGLRWKHUDS\ 1LQHW\WKUHH SDWLHQWV   DQG IRUW\ SDWLHQWV   ZHUH DYDLODEOH IRU WKH  DQG  month follow-up, respectively. Total median serum PSA levels were 0,020 ng/dl(0-0.50), 1 year from surgery. At the 4 month follow-up, 86(92.4%) were completely continent, the use of 1 pad per day was reported in 5 patients (5.4%), and only 2 patients (2.2%) used 2 or more pads per day.

In 21,8% positive margins were detected overall. 12,5% for S7WXPRXUVIRUS7DDQGIRUS7EWXPRXUV$IWHUWKH introduction of standardized frozen sections we determined a rate of 7,2% LQDOOVWDJHVRIWXPRXUIRUS7WXPRXUVIRUS7DDQG IRUS7EWXPRXUV Conclusions: After introducing standardized frozen sections, the number of positive margins in all stages of tumour could be reduced. It needs to be discussed if this is only determined by the surgeons learning curve. It can be stated that the surgeon thus gains more oncological information and certainty in cooperating with his pathologist. We have to look at the data in future for PSA-relapse and progression free survival in comparison to the margin status earliest 5 years after radical prostatectomy.
