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.

Modifiable Factor

Background: Partial nephrectomy is a common treatment for the removal of renal masses. Typically, during the procedure, stitches are used to close two layers of the kidney—both deep and superficial. Renorrhaphy of the superficial layer, thought to reduce the risk of bleeding and urine leak, is routinely performed but has not been sufficiently studied. Hypothesis: Cortical renorrhaphy is a modifiable factor affecting renal function after partial nephrectomy. Omitting this step will preserve renal parenchyma without significantly increasing complications. Methods: A randomized, controlled trial is underway. Interim statistical analysis has been performed on the data being collected. Patients underwent partial nephrectomy with or without cortical renorrhaphy according to their randomized group assignment. Three-dimensional models were constructed using semi-automatic segmentation planimetry of the kidney prior to surgery and at 4-months after tumor resection to determine volume loss in the operated kidney. Results: The median (range) volume loss in the non-renorrhaphy group (n=8), 13% (0-24%), was trending lower than the renorrhaphy group (n=8), 22% (12-39). Using multiple linear regression, experimental group (p=0.0808) and warm-ischemia time (p=0.0995) were significant at the 0.1 level. Tumor size was not statistically significant (p=0.2644). There was one Clavien 3 complication in each group: The renorrhaphy group had one urine leak requiring a drain, and the non-renorrhaphy group had one postoperative bleed requiring selective embolization. Demographics were comparable among the two groups with both having 4 white males and 4 white females. The mean age (58 and 55 for renorrhaphy and non-renorrhaphy, respectively) and tumor size were also comparable. Conclusion and impact: A trend of increased volume loss from cortical renorrhaphy is seen as predicted by retrospective data. Completion of the trial is needed to conclude whether this is statistically significant.

Advances in imaging techniques (CT and MRI) and widespread use of imaging especially ultrasound scanning have resulted in a dramatic increase in the detection of small renal masses. While open partial nephrectomy is still the reference standard for the management of these small renal masses, its associated morbidity has encouraged clinicians to exploit the advancements in minimally invasive ablative techniques. The last decade has seen the rapid development of laparoscopic partial nephrectomy and novel ablative techniques such as, radiofrequency ablation (RFA), high-intensity focused ultrasound (HIFU), and cryoablation (CA). In particular, CA for small renal masses has gained popularity as it combines nephron-sparing surgery with a minimally invasive approach. Studies with up to 5-year followup have shown an overall and cancer-specific 5-year survival of 82% and 100%, respectively. This manuscript will focus on the principles and clinical applications of cryoablation of small renal masses, with detailed review of relevant literature.

402 Background: Although nephron-sparing surgery is the standard of care for the treatment of small renal masses, partial nephrectomy (PN) remains under-utilized. A potential reason for the discrepancy is the desire for minimally invasive surgical approaches but limitation of the advanced laparoscopic techniques needed to perform PN. Robot-assisted surgery has eased the transition to minimally invasive prostate surgery and may also do so for PN, although some believe costs may be prohibitive. The purpose of this investigation was to quantify the cost of robot-assisted PN (RAPN) compared to laparoscopic PN (LPN). Methods: An institutional renal tumor database was used to identify consecutive patients with normal renal function who underwent RAPN for a localized renal mass by a single surgeon who had performed < 25 previously. The 35 RAPN patients were compared to the last 35 similar patients who underwent LPN by a surgeon who had performed > 150 previous LPNs. Surgical outcomes were compared. Because room time, length of stay and Cxs were similar, cost was compared based only on the total operating room charges (ORC). Total ORC included surgeon and anesthesia fees, as well as labor and supply costs. The depreciation of the robot was included in the ORC as a higher per unit time charge than for LPN. Data on charges were available for the first 29 RAPN patients which were then compared to the last 29 LPN patients. Results: Dates of operation ranged from October 2008 to July 2009 for LPN and January 2010 to August 2010 for RAPN. Patient and tumor characteristics were similar between groups, except tumor size, which was larger in the RAPN group (3.6 ± 1.8 cm vs. 2.7 ± 0.9 cm, p = 0.007). Cxs, surgical and oncologic outcomes were similar. Mean ORC (IQR) for the LPN group was $28,606 (4,796) and for the RAPN group was $30,874 (20,389) representing a difference of $2,269. If you subtract an additional $858 for the average yearly inflation rate (3%), the difference is $1,411. Conclusions: RAPN is a safe option with perioperative outcomes similar to those of LPN performed by an experienced surgeon. A cost difference of $2,269 per procedure as estimated using ORC may decrease as the experience of the operating room staff and surgeon increase. No significant financial relationships to disclose.
