OBJECTIVE We investigated whether diabetes mellitus is associated with the cancer-related outcomes in patients with localized clear cell renal cell carcinoma treated with radical or partial nephrectomy. METHODS We reviewed data from 950 patients who received radical or partial nephrectomy for localized clear cell renal cell carcinoma from 1988 to 2009. We(More)
This work demonstrates a large-scale batch fabrication of GaN light-emitting diodes (LEDs) with patterned multi-layer graphene (MLG) as transparent conducting electrodes. MLG films were synthesized using a chemical vapor deposition (CVD) technique on nickel films and showed typical CVD-synthesized MLG film properties, possessing a sheet resistance of(More)
Graphene is a promising next-generation conducting material with the potential to replace traditional electrode materials such as indium tin oxide in electrical and optical devices. It combines several advantageous characteristics including low sheet resistance, high optical transparency and excellent mechanical properties. Recent research has coincided(More)
PURPOSE To evaluate whether the risk of prostate cancer was different according to the pattern of fluctuation in prostate-specific antigen (PSA) levels in patients undergoing repeat transrectal ultrasound-guided prostate biopsy (TRUS-Bx). METHODS From March 2003 to December 2012, 492 patients underwent repeat TRUS-Bx. The patients were stratified into 3(More)
The Seoul National University Renal Stone Complexity (S-ReSC) score is a well-validated tool for the prediction of stone-free rate (SFR) after percutaneous nephrolithotomy. We modified the S-ReSC score system for application to retrograde intrarenal surgery (RIRS) and evaluated this score. A total of 88 patients who underwent RIRS from 2011 to 2013 were(More)
BACKGROUND AND PURPOSE Robot-assisted partial nephrectomy (RPN) has emerged as a viable alternative to open partial nephrectomy (OPN) for small renal masses (SRMs). Comparative outcomes of RPN and OPN at a single institution were analyzed. PATIENTS AND METHODS A retrospective review was performed to compare 69 RPNs with 234 OPNs between May 2003 and(More)
UNLABELLED What's known on the subject? and What does the study add? Previously, it has been reported that PSA may not perform as accurately as PSA density (PSAD) in predicting outcomes after radical prostatectomy among patients with Gleason score 6 prostate cancer. However, there have been few studies comparing the usefulness of PSA and PSAD in predicting(More)
PURPOSE The aim of this study was to evaluate the recent changes in the clinicopathologic features of prostate cancer in Korea and to compare these features with those of Western populations. MATERIALS AND METHODS We retrospectively reviewed the data of 1582 men undergoing radical prostatectomy for clinically localized prostate cancer between 1995 and(More)
OBJECTIVES Currently, no standardized method is available to predict success rate after percutaneous nephrolithotomy. We devised and validated the Seoul National University Renal Stone Complexity (S-ReSC) scoring system for predicting the stone-free rate after single-tract percutaneous nephrolithotomy (sPCNL). PATIENTS AND METHODS The data of 155(More)
OBJECTIVE The objective of our study was to assess the prognostic value of body mass index (BMI) according to histologic subtype in nonmetastatic renal cell carcinoma (RCC), based on a large multicenter experience. METHODS A total of 2769 patients with nonmetastatic RCC at the time of surgery were enrolled from 5 Korean institutions between 1999 and 2011.(More)
