Brief Summary:
The study is a prospective randomized controlled trail to compare early urinary continence recovery after robotic-assisted radical prostatectomy with or without sustainable functional urethral reconstruction (SFUR).

Condition or disease Intervention/treatment Phase
Prostate Cancer Urinary Incontinence Procedure: SFUR-RARP Procedure: Standard RARP Not Applicable

Detailed Description:
Early urinary incontinence has always been a tricky problem for both patients and urologists, even though over 90% patients can recover 12 months after operation. Many urologists are trying to improve the surgery, but these new technics mainly help locally advanced prostate cancer by better preserving Neurovascular Bundles, urethra, external sphincter or other periurethral supporting structures. Sustainable functional urethral reconstruction (SFUR) is a novel technic which can improve early urinary incontinence for both locally and locally advanced prostate cancer, and even for those with high volume prostate by providing adequate urethral length with bladder neck tubularization and sustainable periurethral support with peritoneal flap. The purpose of this study is to compare early continence recovery, oncologic outcomes and postoperative complications after RARP with or without this new technic.

Arm Intervention/treatment
Experimental: SFUR-RARP
Patients in which RARP with sustainable functional urethral reconstruction (SFUR) is performed.
Procedure: SFUR-RARP
Robotic-assisted radical prostatectomy with sustainable functional urethral reconstruction (SFUR)

Active Comparator: Standard RARP
Patients in which standard RARP is performed.
Procedure: Standard RARP
Robotic-assisted radical prostatectomy without sustainable functional urethral reconstruction (SFUR)

Primary Outcome Measures :
  1. Early urinary continence recovery [ Time Frame: 1 month after the removal of the urinary catheter ]
    Number of pads and 24-hour pad weights(Patients with 0 pad/one security liner per day(24-hour pad weights≤50g ) shall be regarded continence)

Secondary Outcome Measures :
  1. Early urinary continence recovery [ Time Frame: one day, 2 weeks and 1 month after catheter removal ]
    Two definitions shall be used: Number of pads(Patients with 0 pad/one security liner per day(24-hour pad weights≤50g ) shall be regarded continence) and early urinary recovery quantification in Grams (PAD-test 24h)

  2. Urinary continence recovery [ Time Frame: within 3/6/12 months from the intervention ]
    Two definitions shall be used: 0 pad/one security liner per day(24-hour pad weights≤50g), and 0 pad per day

  3. Peri and postoperative complications [ Time Frame: 6-month/1-year median follow up ]
    Clavien-Dindo complications

  4. Post-operative oncological outcomes, as defined by post-operative Prostate-Specific antigen (PSA) value [ Time Frame: 1-year median follow up ]
    Patients who reach a post-operative PSA value <0.2 ng/ml will be reported

  5. Evaluation of urinary incontinence [ Time Frame: before surgery, 1 month after catheter removal, 3/6/12 months after surgery ]
    International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF)

  6. Post-operative urinary function and urinary function-related quality of life [ Time Frame: before surgery, 3/6/12 months after surgery ]
    International Prostatic Symptom Score(IPSS)

  7. Post-operative sexual function, as measured by Sexual Health Inventory for Men (SHIM) [ Time Frame: 6-month/1-year median follow up ]
    Two definitions of potency shall be used: SHIM >=17 and erections sufficient for penetrative intercourse
