PURPOSE: Renorrhaphy in partial nephrectomy may damage intraparenchymal vessels and compress the renal parenchyma, which may lead to the formation of renal artery pseudoaneurysms or vascularized parenchymal volume reduction. Using propensity score matching, we compared surgical outcomes following non-renorrhaphy and renorrhaphy techniques for open partial nephrectomy (OPN) for T1a renal tumors. MATERIALS AND METHODS: We retrospectively analyzed data from 159 patients with normal contralateral kidneys who underwent OPN for T1a renal tumors and pre- and postoperative enhanced computed tomography between 2012 and 2015...

Purpose: We propose a quantitative Tc-99m diethylenetriaminepentaacetic acid (DTPA) single-photon emission computed tomography/computed tomography (SPECT/CT) for glomerular filtration rate (GFR) measurement. Methods: Quantitative SPECT/CT data obtained at 2-3 min post-Tc-99m DTPA injection (370 MBq) were used to determine % injected doses (%IDs) for individual kidneys. The reproducibility of %ID measurement was tested and compared with planar scintigraphy. Cr-51 ethylenediaminetetraacetic acid (EDTA) GFR was used as reference standard...

BACKGROUND: Near infrared fluorescence (NIRF) is being investigated as a helpful tool to enhance segmental arterial clamping in robotics. Available experiences with NIRF during standard laparoscopy are anecdotal. The aim of the study was to perform a single-center feasibility and results analysis of laparoscopic partial nephrectomy (LPN) performed using NIRF-guided selective clamping. METHODS: May 2016-December 2016: 15 patients diagnosed with a renal mass suitable for nephron-sparing approach consecutively underwent LPN with NIRF-guidance technique...

Objective: To compare the outcomes of transurethral incision (TUI) and upper pole partial nephrectomy (PN) in patients with duplex system ureterocoele (DSU). Patients and methods: We retrospectively reviewed the medical charts of patients who presented with DSU in the first-year of life and were managed with either TUI or PN. Patients' demographics, ultrasonography examinations, voiding cystourethrogram studies, and dimercaptosuccinic acid scans were reviewed. Also, the postoperative vesico-ureteric reflux status and febrile urinary tract infection occurrences, and subsequent surgical interventions were identified...

BACKGROUND: Xanthogranulomatous pyelonephritis (XGP) is an uncommon chronic destructive granulomatous inflammation of the kidney. It was first described in 1916, and is thought to affect 6/1000 cases of pyelonephritis. Its manifestations are varied, and with a limited number of cases in the literature, the optimal diagnosis and management of XGP in the paediatric cohort is still unknown. MATERIAL AND METHODS: The medical records of children who were diagnosed and treated for XGP at the current unit during the period 1963-2016, inclusive, were retrospectively reviewed...

A 59-year-old woman was referred to our hospital with the finding of an incidentaloma in her right kidney. Computed tomographyand magnetic resonance imaging showed a solid tumor, approximately8 cm in diameter, at the lower pole of the right kidney. Partial nephrectomy was performed without a renal vessel clamp. Histopathologically, fibroblast-like spindle cells were proliferating with rich collagenous fibers, and tumor cells were infiltrated into the renal parenchyma. The tumor cells were stained positive with CD34, CD99, and bcl-2...

OBJECTIVE: To evaluate the impact of hospital volume on outcomes of robot-assisted partial nephrectomy (RAPN). MATERIALS AND METHODS: Patients with renal cell carcinoma who underwent RAPN between 2010 and 2013 were identified in the National Cancer Database. Hospital yearly RAPN volume was categorized into five groups by most closely sorting patients into five groups of equal size (quintiles): very low, low, medium, high, and very high. Outcomes included 30-day mortality, 90-day mortality, open conversion, prolonged length of stay (PLOS, >3 days), 30-day readmission, and positive surgical margin (PSM) rates...

INTRODUCTION: Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies and more than 90% of neoplasms arising from the kidney. Uninformative percutaneous kidney biopsies vary from 10 to 23%. As a result, 7.5-33.6% of partial nephrectomies in patients with small renal masses (SRM) are performed on benign renal tumors. The aim of this study was to assess the feasibility of the apparent diffusion coefficient (ADC) of the diffusion-weighted imaging (DWI) of MRI, as RCC imaging biomarker for differentiation of SRM...

BACKGROUND: Surgical tumour removal remains the preferred treatment for most patients with renal cell carcinoma, and many medical associations have proposed guidelines for the optimal surveillance of patients following surgery. This study evaluated the adherence of Canadian urologists to the follow-up guidelines proposed by the Canadian Urological Association (CUA) in 2009. METHODS: The study cohort was identified from the Canadian Kidney Cancer Information System, a prospectively populated database from 15 academic institutions in 6 Canadian provinces: British Colombia, Alberta, Manitoba, Ontario, Quebec and Nova Scotia...

AIMS: The laparoscopic approach to tumour nephrectomy in children is controversial. We therefore reviewed our institution's cases of tumour nephrectomy (laparoscopic, open, and converted) to better understand which is suitable for this approach, what factors prevent it, and whether one can excise tumours greater than the CCLG recommendation of 300 ml. METHODS: All tumour nephrectomies performed between 2002 and 2016 were identified using our surgical database. Further data were gathered from radiology and pathology databases...

PURPOSE: Preservation of parenchymal mass and ischemia type/duration can influence functional recovery after partial nephrectomy (PN). Some have hypothesized that relevant comorbidities may also impact nephron stability and functional recovery, but this has not been adequately investigated. MATERIALS/METHODS: 405 patients with PN at our center (2007-2015) had necessary data to determine function and parenchymal mass preserved within the ipsilateral kidney. Comorbidities potentially associated with renal functional status were reviewed, including various degrees of hypertension, diabetes, cardiovascular disease, obesity, smoking status, and use of related medications...

INTRODUCTION: The impact of positive surgical margins (PSM) in partial nephrectomy (PN) has been a controversy. Previous studies on the relationship between PSM and overall survival (OS) were either underpowered or had highly dissimilar groups. We used the National Cancer Database with propensity score matching to determine the association between PSM and OS after PN. MATERIALS AND METHODS: We identified patients with T1/T2 N0M0 renal cancer treated with PN between 2004 and 2009, and divided them into 2 groups based on their margin status...

OBJECTIVE: Intraoperative mannitol is routinely administered for renoprotection in partial nephrectomy (PN). However, there is a paucity of evidence supporting mannitol's renoprotective effect. We performed a retrospective study of mannitol's efficacy in PN. METHODS: Using an institutional database, patients undergoing PN from 2006-2016 were retrospectively identified and divided into two groups based on mannitol use. Cases with missing serum creatinine measurements were excluded...

BACKGROUND: Cryoablation has emerged as an alternative to the more invasive partial nephrectomy for small renal masses. The approach can be carried out by two techniques, either laparoscopic (LCA) or percutaneous with CT guidance (PCA). We aimed to compare between the two procedures. MATERIAL & METHODS: A systematic review and meta-analysis was conducted including studies comparing the two techniques. Outcomes included incomplete ablation, late local recurrence, cancer specific survival, procedure time, transfusion rates, hospital stay, and complications...

PURPOSE: To evaluate the importance of preoperative neutrophil lymphocyte ratio (NLR) predicting malignancy in patients who undergo partial nephrectomy due to renal mass. MATERIALS AND METHODS: Seventy nine patients who underwent open partial nephrectomy for renal masses were included in this retrospective study. In preoperative routine blood tests, renal ultrasonography and contrast-enhanced computed tomography were performed for all patients. Preoperative neutrophil lymphocyte ratio were compared in patients with clear cell renal cell carcinoma (Group1, 65 patients) and benign lesions (Group 2, 14 patients)...

PURPOSE: To assess the relationship between De Ritis (aspartate aminotransaminase [AST]/Alanine aminotransaminase [ALT]) ratio and pathological variables and whether it is an independent prognostic factor. MATERIALS AND METHODS: We analyzed 298 consecutive patients who underwent radical or partial nephrectomy for non-metastatic renal cell carcinoma (RCC) between 2006 and 2015. The association between De Ritis ratio and pathological variables including tumor size, presence of renal vein invasion, vena cava invasion, renal capsule infiltration, Gerota fascia invasion, renal sinus involvement, renal pelvic invasion, angiolymphatic invasion, adrenal gland involvement, lymph node involvement, tumor necrosis, and Fuhrman's grade was tested...
