Oncological and functional outcomes of a large Canadian robotic-assisted radical prostatectomy database with 10 years of surgical experience.

Introduction: Robotic-assisted radical prostatectomy (RARP) has grown to be the predominant global surgical approach to treat localized prostate cancer.

Predictors of deviation in neurovascular bundle preservation during robotic prostatectomy.

Introduction: Neurovascular bundle (NVB) preservation during robot-assisted radical prostatectomy (RARP) directly affects patient functional outcomes. Despite careful surgical planning, many NVB preservation techniques are changed intraoperatively from their preoperative plan.

Standardized 4-step technique of bladder neck dissection during robot-assisted radical prostatectomy.

Bladder neck (BN) dissection is considered one of the most challenging steps during robot-assisted radical prostatectomy. Better understanding of the BN anatomy, coupled with a standardized approach may facilitate dissection while minimizing complications. We describe in this article the 4 anatomic spaces during standardized BN dissection, as well other technical maneuvers of managing difficult scenarios including treatment of a large median lobe or patients with previous transurethral resection of the prostate.

Materials And Methods: We prospectively collected data on 250 consecutive patients who underwent RARP by a single surgeon between October 2006 and October 2012. Thirty-six patients were excluded because of lack of preoperative SHIM score.

Feasibility of planned mini-laparotomy and adhesiolysis at the time of robotic-assisted radical prostatectomy in patients with prior major abdominal surgery.

Introduction: Our aim was to report our experience on the feasibility of completing radical prostatectomy robotically after planned open adhesiolysis for prior major abdominal surgery with previous midline laparotomy scar.

Among 250 RARP patients, five patients fulfilled these criteria.

Penile fracture with two ipsilateral corporal tears and delayed presentation: A case report.

Although penile fracture is an infrequent injury, it is a well-described urologic emergency. It results from the rupture of the tunica albuginea of corpora cavernosa by blunt strain that mandates immediate surgical exploration. Reported cases are usually single tear unless contralateral corporal tear is present.

Introduction: We assessed the incidence of contralateral prostate cancer (cPCa), contralateral EPE (cEPE) and contralateral positive surgical margins (cPSM) in patients diagnosed preoperatively with unilateral prostate cancer and evaluated risk factors predictive of contralateral disease extension.

Methods: The occurrence of cPCa, cEPE and cPSM and the side-specific nerve-sparing technique performed were collected postoperatively from 327 men diagnosed with unilateral prostate cancer at biopsy. Parameters, such as the localization, proportion, and percentage of cancer in positive cores, were prospectively collected.

The intent is to help establish a time-based benchmark to aim for during apprenticeship. In addition, we aimed to evaluate preoperative patient factors, which could prolong the operative time of these individual steps.

Uroflow Stop Test and Potency Recovery: A Surrogate for Pelvic Floor Integrity Post Robotic-Assisted Radical Prostatectomy?

Objective: To study the relation between uroflow Stop Test and early recovery of potency following robot-assisted radical prostatectomy (RARP). We recently showed that the ability to completely stop urine flow during voiding, measured objectively by uroflowmetry at the time of catheter removal (uroflow Stop Test) can predict early urinary continence recovery following RARP.

Materials And Methods: In this prospective observational cohort, data were collected on 108 patients operated by a single surgeon (AEH).
