PURPOSE Current radio frequency ablation series do not distinguish renal cell carcinoma subtypes when reporting oncologic efficacy. Papillary neoplasms may be more amenable to radio frequency ablation than clear cell carcinoma because they are less vascular, which may limit heat energy loss. We report the long-term outcomes of patients treated with radio(More)
BACKGROUND Molecular profiling of renal cell carcinomas (RCCs) may improve the distinction between oncocytoma and malignant RCC subtypes and aid in early detection of metastasis. The hyaluronic acid (HA) family includes HA synthases (HAS1, HAS2, HAS3), hyaluronidases (HYAL-1, HYAL-2, HYAL-3, HYAL-4, PH20, HYAL-P1), and HA receptors (CD44s, CD44v, RHAMM). HA(More)
To compare the outcomes of robotic-assisted laparoscopic prostatectomy (RALP) using a dual versus single-console system in a resident training program using intraoperative, perioperative and postoperative measures. Patients with PCa who underwent RALP prior to and after implementing a dual-console system at an academic institution were reviewed from(More)
PURPOSE Molecular characterization of renal cell carcinoma may help differentiate benign oncocytoma from malignant renal cell carcinoma subtypes and predict metastasis. Chemokines, eg IL-8 and chemokine receptors such as CXCR4 and 7, promote inflammation and metastasis. SDF-1 is a CXCR4 and 7 ligand with 6 known isoforms. We evaluated the expression of(More)
PURPOSE Our study sought to demonstrate the effects of remote ischemic preconditioning (R-IPC) on renal function in a large animal (porcine) solitary-kidney model. METHODS Twelve pigs were assigned to two groups: Each underwent a right nephrectomy followed by a week of recovery. Group 1 (No-IPC) underwent left renal hilar clamping for 90 minutes. Group 2(More)
OBJECTIVE To report the long-term oncological and renal function outcomes in healthy adults treated with radiofrequency ablation (RFA) for small renal masses. MATERIALS AND METHODS We retrospectively analysed the medical records of otherwise healthy patients (those with American Society of Anesthesiologists symptom score 1 or 2) with clinical T1a renal(More)
Within the last decade, the adaptation of robotic urologic surgery has had a profound impact on surgical practice, with robotic upper tract reconstruction for ureteropelvic junction obstruction gaining rapid acceptance. Recent advances in robotic reconstruction demonstrate efficacious outcomes of robotic pyeloplasty, as compared with conventional(More)
OBJECTIVE To understand the effective radiation dose during percutaneous cryoablation (CA) and radiofrequency ablation (RFA) and characterize variables that may affect the individual dose. MATERIALS AND METHODS The effective radiation dose was determined by conversion of the dose-length product from CT scans performed during percutaneous CA or RFA for(More)
OBJECTIVES To assess whether the R.E.N.A.L. nephrometry score (consists of [R]adius [tumour size as maximal diameter], [E]xophytic/endophytic properties of the tumour, [N]earness of tumour deepest portion to the collecting system or sinus, [A]nterior [a]/posterior [p] descriptor and the [L]ocation relative to the polar line) is associated with complication(More)
PURPOSE To report one of the largest series of clinical and renal function outcomes of treated iatrogenic vascular lesions (IVL) after partial nephrectomy (PN). Angioembolization (AE) is the treatment of choice for patients with these lesions, but the additional renal injury conferred by this treatment has not been well described. PATIENTS AND METHODS(More)
