Description of intervention(s) / exposure
Participants in the intervention group will first complete a baseline questionnaire when they consent to the trial, and undergo pre-operative urinal functional testing by a urologist (including a perineal/pelvic floor ultrasound, uroflow test and urodynamic assessment). They will then proceed to a robotic-assisted radical prostatectomy surgery, incorporating the construction of a retropubic vascularised fascial sling (RoboSling, the 'intervention'), completed by their treating urological surgeon. The RoboSling is created by dissecting a piece of peritoneum (abdominal lining tissue) off f the rear surface of the bladder, which is then brought underneath the bladder to the front, and top corners of the flap stitched upwards under tension to the pubic bone).
After surgery, intervention participants will complete a series of 6 post-operative questionnaires at set follow-up timepoints up to one year post-operative when visiting their surgeon for post-operative review/management appointments, and again undergo post-operative urinal functional testing at one-year with a urologist.
The control (comparator) group will undergo all these procedures except their surgery will NOT include the construction of a RoboSling.

Participants in the control group will complete a baseline questionnaire, undergo pre-operative urinal functional testing (including a perineal/pelvic floor ultrasound, uroflow test and urodynamic assessment), then proceed to a standard robotic-assisted radical prostatectomy, and afterwards complete a series of 6 post-operative questionnaires at set timepoints up to one year post-operative and undergo post-operative urinal functional testing at one-year.

To determine the impact of incorporating the RoboSling procedure with
robot-assisted radical prostatectomy (RARP) surgeryon early (3 months) and late (1 year) post-operative urinary continence, compared to RARP alone. This will be measures by the rate of patient reported continence defined as 0 urinary pad usage per day at 3 months and 1 year post-operatively.

To identify urinary functional parameters which may differ between the intervention group and the control group.
Urinary function will be measured as a composite outcome: functional parameters assessed will include Qmax, detrusor leak point and pressure, bladder compliance, storage dysfunction (OAB) and voiding dysfunction (BOO, detrusor underactivity, stress or urgency incontinence), pelvic floor contraction and mobility. These will be measured by pre- and post-operative urinary functional tests completed by a urologist, which include a perineal/pelvic floor ultrasound, uroflow test and urodynamic assessment.

To identify differences in peri-operative complications between the intervention group and control group.
Known potential complications of the procedure include pain, urinary incontinence and bleeding, Other less likely complications may include infection, visceral injury, sepsis and death (all extremely unlikely). Incidence of complications will be recorded for each participant and checked through medical record review, and compared between the study groups.

Statistical methods / analysis
Clinically relevant baseline variables will be tabulated and compared between groups.
Categorical variables will be compared between groups using the chi-squared test
(frequencies and proportions). Continuous variables will be compared using t-test (means) or Wilcoxon 2-sample test (median). Unadjusted rates of continence will be compared between groups with the Fisher exact test. All data will be stored in a REDCap database and statistical analysis will be performed using SPSS version 22 (SPSS Inc, Chicago, IL, USA).

Summary
Brief summary
The purposes of this study is to assess the urinary function of men undergoing a prostatectomy with and without a 'RoboSling', which is a thin piece of the patient's abdominal lining tissue that is stitched to the pubic bone during surgery to support the bladder.
Who is it for?
You may be eligible for this study if you are aged at least 18 years and are undergoing a prostatectomy for prostate cancer with one of the participating surgeons involved in this study.
Study details
Participants in this study will be randomised (by chance) into two groups. Both groups will undergo their planed prostatectomy procedure. One group will have a standard procedure, and the other group will have a standard procedure with the creating of a ‘RoboSling’ from their abdominal lining tissue during surgery. All participants will complete a number of questionnaires at 7 timepoints over the weeks and months just prior to and following their surgery.
It is intended that this study will help to improve urinary continence in men after prostatectomy surgery in the future.
