“…Several methods of quantifying these tumours have been proposed as an objective means of pre-operative assessment and will play an increasing role in the future as urologists carefully weigh the risks and benefits of treatment decisions for SRMs. [73][74][75][76] …”

The surgical management of renal masses involves either radical nephrectomy (RN) or partial nephrectomy (PN). PN has been associated with better long-term renal function, and has also been linked to improved cardiac morbidity and overall survival. However, the relationship between treatment choice and definitive outcomes of chronic kidney disease (CKD) are lacking. Our aim was to examine whether PN is associated with a lower risk of end-stage renal disease (ESRD) requiring renal replacement therapy.We performed a population-based, retrospective cohort study with data from linked administrative databases in the province of Ontario, Canada. We included individuals with pathologically confirmed renal cell carcinoma (RCC) diagnosed between 1995 and 2010. Cox proportional hazards (PH) models, propensity score models, and competing risks models were used to assess the impact of treatment choice. PN compared to RN reduces the risk of ESRD requiring renal replacement therapy in a modern cohort of patients (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010). PN is associated with a lower risk of new-onset CKD, lower risk of cardiac morbidity, and improved overall survival. We provide further evidence for the benefit of PN compared to RN, particularly related to definitive outcomes of renal failure.iii ACKNOWLEDGEMENTS

“…For each patient, we registered demographic data and co-morbidities classified according to Charlson's co-morbidity index (CCI) (11)). Radiological tumour size (according to Computed Tomography scan, CT-scan), side and location were considered and lesions were classified according to RENAL nephrometry score (12) and PADUA score (9). Peri-operative, histopathological data and post-operative complications (classified according to Clavien's System (13)) were also recorded.…”

ARTIcLE INFO _________________________________________________________ ___________________Purpose: To evaluate the results of our technique of clampless laparoscopic partial nephrectomy (LPN) and its impact as an emerging treatment for small renal masses (SMRs). Materials and Methods:We reviewed our prospectively maintained database: data of 117 patients who consecutively underwent LPN at our Institution from January 2009 to December 2011 were studied. Patients were divided into 2 Groups based on operative technique: Group A: clampless-LPN (cl-LPN); Group B: conventional LPN (clamping of renal artery). Demographic and peri-operative data, complications, pre-and post-operative serum creatinine and estimated glomerular filtration rate (eGFR) were registered and compared by Student's t-and Chi-square-tests (p-values < 0.05 considered statistically significant).

“…Renal cyst data were assessed according to cyst side (right or left), location (upper, mid or lower pole), characteristics (Bosniak classification 1, 2, or 2f), and exophytic degree which was stratified using the RENAL nephrometry score, as described by Kutikov and Uzzo [9] . According to their definitions, renal tumors that are ≥ 50% exophytic are assigned 1 point, tumors that are < 50% exophytic are assigned 2 points, while those that are entirely endophytic (encircled 360° by uninvolved renal parenchyma) are assigned 3 points.…”

higher than mild and moderate exophytic renal cyst. INTRODUCTIONRenal cysts are acquired lesions that most commonly affect the elderly population [1] . Autopsy studies have reported a 50% incidence of renal cysts after the age of 50 years [2] . The prevalence of renal cysts is approximately 10%, ranging from 4% in the third decade to 19% in the sixth decade [3] . There is an increase in the size and number of cysts over time in cyst-bearing individuals. Previous longterm follow-up data have shown that, simple renal cysts continue to increase in size with age > 10 years, and sometimes increase rapidly, particularly in younger patients [4] . However, this study also showed decreased growth rate of cysts with increased age. Renal cysts originate from weakened of the tubular basement membrane of the distal convoluted or collecting duct cells [2] . As results, a diverticulum is formed, which can subsequently develop into a simple renal cyst [5,6] . The reported risk factors for renal cysts include old age, male gender, renal dysfunction, and hypertension [7] . However, given the retrospective nature of these studies, the associations could be coincidental. The only persistent confounder among all reported associations was increasing age [4,7,8] . Therefore, we analyzed the discrepancy of an increasing rate of simple renal cysts according to initial size, location, and exophytic index stratified using the RENAL nephrometry scoring system in this study. MATERIALS AND METHODS Study populationThis study was conducted after receiving approval from our ABSTRACT AIM: To investigate the growth patterns of renal cysts according to location, exophytic degree and Bosniak classification. METHODS: From December 2000 to September 2012, a total of 252 patients (340 renal cysts) were included in this study. All patients had undergone computed tomography (CT) scans of the kidney level at least twice, and six months apart for any reason. Renal cyst data were assessed according to cyst side (right or left), location (upper, mid or lower), characteristics (Bosniak classification), and exophytic degree (1,2, and 3) which were stratified using the RENAL nephrometry score. The growth rate of renal cyst was analyzed according to each parameter using linear correlation analysis. RESULTS:The mean size of renal cyst increased from 3.81 cm to 3.85 cm during a mean follow-up of 20.1 months, not significantly (p = 0.121). Among 340 renal cyst units, 180 renal cysts had an exophytic degree index of 1 (52.9%), 90 had an index 2 (26.5%), and 70 had an index of 3 (20.6%). After a mean of 20.1 months of follow-up, only exophytic degree 3 renal cysts increased in size significantly from 4.54 to 5.76 cm (p = 0.018). The annual growth rate in exophytic degree 3 renal cysts was 2.4 mm (r 2 = 0.263), which was higher than that for renal cysts at other site locations. CONCLUSION: The growth rate of renal cysts varied according to exophytic location. The growth rate of exophytic renal cysts was
