Introduction: We evaluated the the association between PADUA scores and postoperative renal function (after robot-assisted partial nephrectomy [RAPN]) and between PADUA scores and warm ischemic time (during RAPN).Methods: We reviewed the clinical records of 106 patients who underwent RAPN for a single localized renal tumour between April 2009 and June 2012. Postoperative renal function was evaluated using estimated glomerular filtration rate (eGFR) in 85 patients who were followed for at least 6 months. PADUA scores for renal tumours were calculated using contrast-enhanced computed tomography images, if needed, along with magnetic resonance images in some cases.Results: A PADUA score ≥10 and WIT ≥30 minutes were observed in 18 (17.0%) and 51 (48.1%) cases, respectively. PADUA scores were significantly correlated with WIT (p = 0.019) and percent change in eGFR at 6 months postoperatively (p = 0.005). PADUA score (continuous variable, odds ratio [OR] 1.694, p = 0.007) and the high-risk group (PADUA score ≥10) (OR 5.429; p = 0.020) were significantly associated with a WIT of ≥30 minutes by multivariate analysis. A 1-point increase in the PADUA score was associated with an eGFR decrease of >20% at 6 months after RAPN (OR 1.799; p = 0.076). In addition, a PADUA score ≥10, or high risk, (OR 13.965; p = 0.003) was an independent predictor of an eGFR decrease of >20% at 6 months after RAPN.Conclusions: The PADUA classification can reliably predict WIT and postoperative renal functional outcome after RAPN. Furthermore, the study suggests that anatomical aspects of renal tumours are associated with functional outcome after RAPN.

Preserving renal function and controlling oncological outcomes are pertinent when managing renal neoplasms. Cryoablation is the recommended treatment only for clinical T1a stage renal tumour. Here, we compared the outcomes of robot-assisted laparoscopic partial nephrectomy (RaPN) and laparoscopic cryoablation (LCA) in the treatment of patients with localised T1-T2 renal tumours. Overall, 86 patients who received RaPN and 78 patients underwent LCA were included in this study. The intraoperative, postoperative, and oncological outcomes in the LCA group were non-inferior to the RaPN group. Moreover, LCA demonstrated shorter operative time (267.45 ± 104.53 min vs. 138.56 ± 45.28 min, p < 0.001), lower blood loss (300.56 ± 360.73 mL vs. 30.73 ± 50.31 mL, p < 0.001), and slight renal function deterioration because of the reduced invasiveness, without compromising on the oncological outcomes.

Between January 1, 2011, and January 1, 2017, an orthopaedic foot and ankle surgeon performed tibiotalar arthrodesis on 221 patients. Thirty-two were included in this study. Inclusion criteria included patients with at least one risk factor for nonunion and/or malunion, isolated anterior ankle arthrodesis with plate fixation, patients older than 18, and a minimum of 1-year follow-up. Risk factors were avascular necrosis of the talus, severe segmental bone defect, smoking, inflammatory arthropathy, coronal deformity greater than 15°, diabetes mellitus, septic nonunion, failed ankle arthrodesis, and body mass index greater than 35. Functional outcome questionnaires (Ankle Osteoarthritis Score [AOS] and Foot Function Index [FFI]) were collected at the latest visit or by phone. Twenty-six (26/32, 81.2%) patients included in the study had computed tomography images available for review at an average of 3.2 months after surgery. The rate of successful arthrodesis was 93.8% (30/32) at an average of 78 days. Overall, 14 patients (14/32, 43.8%) developed a postoperative complication, including 1 patient that had a delayed nonunion and 2 patients that proceeded to nonunion. Twenty-three patients (23/32, 71.9%) completed the functional outcome questionnaires at an average of 26.8 months. Mean AOS and FFI scores improved significantly postoperatively ( P < .001). Sagittal tibiotalar and coronal tibiotalar alignment improved significantly in patients with severe preoperative deformity ( P < .001). Tibiotalar arthrodesis with anterior plate fixation in a high-risk cohort results in high union rates and significantly improved functional outcomes. Levels of Evidence: Therapeutic, Level IV: Prospective, comparative trial.

Robotic Assisted Partial Nephrectomy

Over the past few years, the role of robotic-assisted partial nephrectomy (RPN) has exponentially grown. Multiple recognized factors contribute to postoperative renal function in patients undergoing RPN. The aim of this review is to identify these potential factors, and to evaluate strategies that may help optimize the goal of renal function preservation. A nonsystematic literature review was performed to retrieve the most recent evidence on factors contributing to renal function post-RPN. Analyzed elements include baseline factors (tumor complexity and patient characteristics), intraoperative (surgical) factors (control of the renal hilum and type of ischemia, resection technique, renorrhaphy technique), and pharmacotherapeutics. In conclusion, the advantages of robotic surgery in the setting of partial nephrectomy (PN) are becoming well established. Maximal preservation of renal function remains a priority goal of the procedure, and it is influenced by a plethora of factors. Adequate patient selection using radiomics, control of comorbidities, utilization of evidence-based intraoperative techniques/strategies, and postoperative care are key components of postoperative preservation of renal function. Further investigations regarding these factors and their effects on long-term renal function are necessary and will continue to aid in guiding appropriate patient care.
