To assess and compare the short-term post-operative continence recovery rate in two cohorts of men undergoing Robot Assisted Radical Prostatectomy (RARP), each randomized to undergo RARP with Vattikuti Institute technique or Retzius sparing technique.

Traditionally, RARP is performed using a trans-peritoneal technique that pass anteriorly to the bladder. This technique necessitates the dissection and/or manipulation of many structures, which might compromise post-operative urinary continence recovery. These structures include the pubo-prostatic ligament, Santorini plexus, neurovascular bundle, and veil of Aphrodite. Recently, a "Retzius-sparing" technique to perform RARP has beed described. This approach passes posteriorly to the bladder, through the space of Douglas, which should minimize the damaged to the aforementioned structure. Theoretically, the latter technique should improve post-operative urinary continence recovery. However, a randomized comparison between the "traditional" RARP and "Retzius-sparing" RARP is still lacking.

Impact of Robot-assisted Radical Prostatectomy Technique on Short-term Continence Recovery

The Impact of Retzius-sparing Approach for Robot-assisted Laparoscopic Radical Prostatectomy on Short-term Continence Recovery: Randomized Controlled Trial

MSKCC (Memorial Sloan Kettering Cancer Center) STAR questionnaire (symptom tracking and reporting). Score ranges from 0-25, with higher scores indicating better urinary function

SHIM ranges from 0-25 with higher scores indicating better sexual function; a score of \>=22 is normal and \>=17 is considered mild ED

Patients without biochemical evidence of disease recurrence (i.e. postop PSA \>=0.2 ng/mL)

International Prostatic Symptom Score (continuous score from 0-35, higher scores indicating worse urinary function)

NCCN (National Comprehensive Cancer Network) risk categorizes prostate cancer based on their likelihood of disease progression, recurrence and outcomes, into low, intermediate, high and very high risk groups. It uses clinical information (i.e information available PRIOR to surgery) for this (i.e PSA, biopsy gleason score and clinical T stage)

Number of Participants With Urinary Continence Recovery

Number of Participants With Peri and Postoperative Complications

Number of Participants Who Regained Potency Postoperatively (as Measured by Sexual Health Inventory for Men (SHIM) Score of 17 or Greater)

Number of Participants Who Had Biochemical Recurrence (Post-operative Prostate-Specific Antigen (PSA) Value >=0.2 ng/ml)

Post-operative Urinary Function and Urinary Function-related Quality of Life

Number of Patients Who Regained Urinary Continence Postoperatively

The numbers in this analyses are different from the primary analyses as some patients were lost to follow up (by one year)
