Introduction: The Hemopatch ® is a novel polyethylene glycol-coated (PEG-coated) collagen patch that acts as a topical hemostatic agent. It has been applied to a variety of surgical techniques. Here, we present our series and technique using a PEG-coated patch for minimally invasive partial nephrectomy (MIPN)., Methods: We conducted a retrospective chart review of all patients undergoing MIPN by a single surgeon at a tertiary Canadian medical center between July and December 2018. We included patients if a PEG-coated patch was used to close the renal parenchymal defect. We also describe in detail our technique for laparoscopic patch deployment., Results: A total of 17 patients met inclusion criteria, of whom 12 were male. Mean age was 63 years old. Median size of renal mass was 2.85 cm in largest dimension and median RENAL score was 6. Hilar clamping was carried out in 12 (70.9%) cases, with an average warm ischemic time of 16.1 minutes. The remainder of cases were performed off-clamp. Median estimated blood loss was 238 mL and the mean change in hemoglobin on postoperative day 1 compared to preoperatively was 21.2 g/L. The average length of stay was 1.76 days. No patient required blood transfusion or underwent angioembolization or re-operation for bleeding within 90 days. There were no Clavien-Dindo grade 3 or greater complications., Conclusions: A PEG-coated patch can be used safely and effectively in lieu of traditional two-layer renorrhaphy with acceptable outcomes. Larger, prospective series are required to ascertain its true value and cost-effectiveness.

Introduction: Partial nephrectomy remains the gold standard in the management of small renal masses. However, minimally invasive partial nephrectomy (MIPN) is associated with a steep learning curve, and optimal, standardized techniques for time-efficient hemostasis are poorly described. Given the relative lack of evidence, the goal was to describe a set of actionable guiding principles, through an expert working panel, for urologists to approach hemostasis without compromising warm ischemia or oncological outcomes., Methods: A three-step modified Delphi method was used to achieve expert agreement on the best practices for hemostasis in MIPN. Panelists were recruited from the Canadian Update on Surgical Procedures (CUSP) Urology Group, which represent all provinces, academic and community practices, and fellowship-and non-fellowship-trained surgeons. Thirty-two (round 1) and 46 (round 2) panellists participated in survey questionnaires, and 22 attended the in-person consensus meeting., Results: An initial literature search of 945 articles (230 abstracts) underwent screening and yielded 24 preliminary techniques. Through sequential survey assessment and in-person discussion, a total of 11 strategies were approved. These are temporally distributed prior to tumor resection (five principles), during tumor resection (two principles), and during renorrhaphy (four principles)., Conclusions: Given the variability in tumor size, depth, location, and vascularity, coupled with limitations of laparoscopic equipment, achieving consistent hemostasis in MIPN may be challenging. Despite over two decades of MIPN experience, limited evidence exists to guide clinicians. Through a three-step Delphi method and rigorous iterative review with a panel of experts, we ascertained a guiding checklist of principles for newly beginning and practicing urologists to reference.

Introduction: Abdominal sacrocolpopexy provides effective long-term outcomes for apical pelvic organ prolapse. The introduction of robotic-assisted laparoscopic sacrocolpopexy (RALS) has mitigated the risks of abdominal surgery. This study aims to evaluate the preoperative patient characteristics, intraoperative surgical parameters, and postoperative outcomes of RALS, which has not been previously performed in Canada., Methods: A retrospective chart review of 47 patients who have undergone RALS from 2016-2018 by a single surgeon at a tertiary care hospital in Canada was completed., Results: This case series had a mean age of 60.2 years, body mass index (BMI) of 28.3 kg/m 2 , and Charlson comorbidity index of 2.0. Preoperatively, 13 (28%), 23 (49%), and 11 (23%) patients had Baden-Walker grade 2, 3, and 4 apical prolapse, respectively. Intraoperatively, 45 (96%) patients underwent concomitant procedures, including 36 (77%) with adnexal surgery, 32 (68%) with anti-incontinence surgery, and 25 (53%) with hysterectomy. Intraoperative complications included one ureteric injury, two bladder injuries, and three vaginotomies. The mean robotic console time, surgery time, and total operating room times were 125.6, 148.6, and 190.6 minutes, respectively. Postoperatively, data was analyzed for 32 (68%) patients with greater than 12 weeks' followup. There was no recurrence of apical prolapse on exam after a mean followup of 60.1 weeks. Seven (22%) patients experienced symptomatic prolapse in the posterior compartment. There were two grade 3 Clavien-Dindo complications, including osteomyelitis and mesh exposure., Conclusions: RALS can be safely and effectively performed with other pelvic procedures with good outcomes. Concurrent posterior repairs may be considered in select patients.
