    Input: INTRODUCTION Lack of r and omized controlled trials ( RCTs ) that compare pure laparoscopic radical prostatectomy ( LRP ) with robot-assisted laparoscopic radical prostatectomy ( RALRP ) is an important gap of the literature related to the surgical treatment of the clinical ly localized prostate cancer ( PCa ) . AIM To provide the first prospect i ve r and omized comparison on the functional and oncological outcomes of LRP and RALRP for the treatment of the clinical ly localized PCa . METHODS Between 2007 and 2008 , 128 consecutive male patients were r and omized in two groups and treated by a single experienced surgeon with traditional LRP ( Group I-64 patients ) or RALRP ( Group II-64 patients ) in all cases with intent of bilateral intrafascial nerve sparing . MAIN OUTCOME MEASURES Primary end point was to compare the 12 months erectile function ( EF ) outcomes . Complication rates , continence outcomes , and oncological results were also compared . The sample size of our study was able , with an adequate power ( 1-beta > 0.90 ) , to recognize as significant large differences ( above 0.30 ) between incidence proportions of considered outcomes . RESULTS No statistically significant differences were observed for operating time , estimated blood loss , transfusion rate , complications , rates of positive surgical margins , rates of biochemical recurrence , continence , and time to continence . However , the 12-month evaluation of capability for intercourse ( with or without phosphodiesterase type 5 inhibitors ) showed a clear and significant advantage of RALRP ( 32 % vs. 77 % , P < 0.0001 ) . Time to capability for intercourse was significantly shorter for RALRP . Rates of return to baseline International Index of Erectile Function ( IIEF-6 ) EF domain score question naires ( questions 1 - 5 and 15 ) ( 25 % vs. 58 % ) and to IIEF-6 > 17 ( 38 % vs. 63 % ) were also significantly higher for RALRP ( P = 0.0002 and P = 0.008 , respectively ) . CONCLUSIONS Our study offers the first high-level evidence that RALRP provides significantly better EF recovery than LRP without hindering the oncologic radicality of the procedure . Larger RCTs are needed to confirm if a new gold-st and ard treatment in the field of RP has risen PURPOSE Robotic assisted laparoscopic radical cystectomy for bladder cancer has been reported with potential for improvement in perioperative morbidity compared to the open approach . However , most studies are retrospective with significant selection bias . MATERIAL S AND METHODS A pilot prospect i ve r and omized trial evaluating perioperative outcomes and oncologic efficacy of open vs robotic assisted laparoscopic radical cystectomy for consecutive patients was performed from July 2009 to June 2011 . RESULTS To date 47 patients have been r and omized with data available on 40 patients for analysis . Each group was similar with regard to age , gender , race , body mass index and comorbidities , as well as previous surgeries , operative time , postoperative complications and final pathological stage . We observed no significant differences between oncologic outcomes of positive margins ( 5 % each , p = 0.50 ) or number of lymph nodes removed for open radical cystectomy ( 23 , IQR 15 - 28 ) vs robotic assisted laparoscopic radical cystectomy ( 11 , IQR 8.75 - 21.5 ) groups ( p = 0.135 ) . The robotic assisted laparoscopic radical cystectomy group ( 400 ml , IQR 300 - 762.5 ) was noted to have decreased estimated blood loss compared to the open radical cystectomy group ( 800 ml , IQR 400 - 1,100 ) and trended toward a decreased rate of excessive length of stay ( greater than 5 days ) ( 65 % vs 90 % , p = 0.11 ) compared to the open radical cystectomy group . The robotic group also trended toward fewer transfusions ( 40 % vs 50 % , p = 0.26 ) . CONCLUSIONS Our study vali date s the concept of r and omizing patients with bladder cancer undergoing radical cystectomy to an open or robotic approach . Our results suggest no significant differences in surrogates of oncologic efficacy . Robotic assisted laparoscopic radical cystectomy demonstrates potential benefits of decreased estimated blood loss and decreased hospital stay compared to open radical cystectomy . Our results need to be vali date d in a larger multicenter prospect i ve r and omized clinical trial BACKGROUND The absence of trial data comparing robot-assisted laparoscopic prostatectomy and open radical retropubic prostatectomy is a crucial knowledge gap in uro-oncology . We aim ed to compare these two approaches in terms of functional and oncological outcomes and report the early postoperative outcomes at 12 weeks . METHOD In this r and omised controlled phase 3 study , men who had newly diagnosed clinical ly localised prostate cancer and who had chosen surgery as their treatment approach , were able to read and speak English , had no previous history of head injury , dementia , or psychiatric illness or no other concurrent cancer , had an estimated life expectancy of 10 years or more , and were aged between 35 years and 70 years were eligible and recruited from the Royal Brisbane and Women 's Hospital ( Brisbane , QLD ) . Participants were r and omly assigned ( 1:1 ) to receive either robot-assisted laparoscopic prostatectomy or radical retropubic prostatectomy . R and omisation was computer generated and occurred in blocks of ten . This was an open trial ; however , study investigators involved in data analysis were masked to each patient 's condition . Further , a masked central pathologist review ed the biopsy and radical prostatectomy specimens . Primary outcomes were urinary function ( urinary domain of EPIC ) and sexual function ( sexual domain of EPIC and IIEF ) at 6 weeks , 12 weeks , and 24 months and oncological outcome ( positive surgical margin status and biochemical and imaging evidence of progression at 24 months ) . The trial was powered to assess health-related and domain-specific quality of life outcomes over 24 months . We report here the early outcomes at 6 weeks and 12 weeks . The per- protocol population s were included in the primary and safety analyses . This trial was registered with the Australian New Zeal and Clinical Trials Registry ( ANZCTR ) , number ACTRN12611000661976 . FINDINGS Between Aug 23 , 2010 , and Nov 25 , 2014 , 326 men were enrolled , of whom 163 were r and omly assigned to radical retropubic prostatectomy and 163 to robot-assisted laparoscopic prostatectomy .  18 withdrew ( 12 assigned to radical retropubic prostatectomy and six assigned to robot-assisted laparoscopic prostatectomy ) ; thus , 151 in the radical retropubic prostatectomy group proceeded to surgery and 157 in the robot-assisted laparoscopic prostatectomy group . 121 assigned to radical retropubic prostatectomy completed the 12 week question naire versus 131 assigned to robot-assisted laparoscopic prostatectomy . Urinary function scores did not differ significantly between the radical retropubic prostatectomy group and robot-assisted laparoscopic prostatectomy group at 6 weeks post-surgery ( 74·50 vs 71·10 ; p=0·09 ) or 12 weeks post-surgery ( 83·80 vs 82·50 ; p=0·48 ) . Sexual function scores did not differ significantly between the radical retropubic prostatectomy group and robot-assisted laparoscopic prostatectomy group at 6 weeks post-surgery ( 30·70 vs 32·70 ; p=0·45 ) or 12 weeks post-surgery ( 35·00 vs 38·90 ; p=0·18 ) . Equivalence testing on the difference between the proportion of positive surgical margins between the two groups ( 15 [ 10 % ] in the radical retropubic prostatectomy group vs 23 [ 15 % ] in the robot-assisted laparoscopic prostatectomy group ) showed that e quality between the two techniques could not be established based on a 90 % CI with a Δ of 10 % . However , a superiority test showed that the two proportions were not significantly different ( p=0·21 ) . 14 patients ( 9 % ) in the radical retropubic prostatectomy group versus six ( 4 % ) in the robot-assisted laparoscopic prostatectomy  group had postoperative complications ( p=0·052 ) . 12 ( 8 % ) men receiving radical retropubic prostatectomy and three ( 2 % ) men receiving robot-assisted laparoscopic prostatectomy  experienced intraoperative adverse events . INTERPRETATION These two techniques yield similar functional outcomes at 12 weeks . Longer term follow-up is needed . In the interim , we encourage patients to choose an experienced surgeon they trust and with whom they have rapport , rather than a specific surgical approach . FUNDING Cancer Council Queensl and To compare health‐related quality ‐of‐life ( HRQoL ) outcomes for robot‐assisted laparoscopic radical cystectomy ( RARC ) with those of traditional open radical cystectomy ( ORC ) in a prospect i ve r and omised fashion Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more 284 Background : We reported our results on a prospect i ve , r and omized trial of open vs. robotic cystectomy in 2008 . Three years later , we report our findings with regard to overall ( OS ) and disease-specific survival ( DS ) , recurrence rates and long-term complications . METHODS A prospect i ve , r and omized study comparing open vs. robotic cystectomy for bladder cancer was initiated at our institution with IRB approval in 2008 . A target accrual of 40 patients was established to evaluate for non-inferiority based upon nodal yield . Peri-operative and pathologic results were reported in 2008 . We now report our median 36-month follow-up for this patient cohort . RESULTS Of the 41 patients , 21 were r and omized to robotic and 20 to open . On surgical pathology , in the robotic group 14 patients had < = pT2 , 3 pT3/T4 , and 4 N+ disease . In the open group , 9 had < = pT2 , 5 pT3/T4 , and 7 N+ disease . No positive margins were noted . With median follow-up of 35 and 36 months in the robotic and open arms , OS was 65 % ( 13/20 ) and 81 % ( 17/21 ) respectively ( p=0.3058 ) . DSS was 68 % in the open group ( 13/19 ) and 85 % in the robotic group ( 17/20 ) ( p=0.2733 ) . There were 7 recurrences ( 35 % ) in the open cohort compared to 3 patients ( 14 % ) undergoing the robotic procedure ( p=0.1589 ) . Examining overall complications , there were no differences between the open and robotic groups when evaluating 30-day complications and > = 90 day complications ( p=0.8651 ) . The open and robotic cohorts demonstrated 2 strictures in each cohort . Two parastomal hernias were noted in the open group compared to none in the robotic group . On multivariate analysis , controlling for age , BMI and pathologic stage , cystectomy type did not predict OS or DSS , recurrences , or complications . CONCLUSIONS Median 3-year follow-up evaluating open versus robotic cystectomy demonstrates no differences with regard to OS , DSS , cancer recurrence or long-term complications . Although this study was not powered to assess survival differences , this is the first r and omized study to report such data in a non-selected population with 3-year median follow-up BACKGROUND Open radical cystectomy ( ORC ) and urinary diversion in patients with bladder cancer ( BCa ) are associated with significant perioperative complication risk . OBJECTIVE To compare perioperative complications between robot-assisted radical cystectomy ( RARC ) and ORC techniques . DESIGN , SETTING , AND PARTICIPANTS A prospect i ve r and omized controlled trial was conducted during 2010 and 2013 in BCa patients scheduled for definitive treatment by radical cystectomy ( RC ) , pelvic lymph node dissection ( PLND ) , and urinary diversion . Patients were r and omized to ORC/PLND or RARC/PLND , both with open urinary diversion .  Patients were followed for 90 d postoperatively . INTERVENTION St and ard ORC or RARC with PLND ; all urinary diversions were performed via an open approach . OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Primary outcomes were overall 90-d grade 2 - 5 complications defined by a modified Clavien system . Secondary outcomes included comparison of high- grade complications , estimated blood loss , operative time , pathologic outcomes 
    Output:
    
Robotic surgery is comparable with laparoscopic or open surgery for oncological outcomes and overall complications , and provides somewhat better functional outcome when compared with laparoscopic and open surgery
