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)
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)
UNLABELLED There has been some controversy about the gender differences in survival in patients with RCC. Korean women with RCC had a lower proportion of clear cell histology and a higher proportion of chromophobe histology. This histological difference might have driven the better survival rates in Korean women. OBJECTIVE To assess whether there are(More)
We fabricated 8 × 8 cross-bar array-type flexible organic resistive memory devices with transparent multilayer graphene (MLG) electrodes on a poly(ethylene terephthalate) substrate. The active layer of the memory devices is a composite of polyimide and 6-phenyl-C61 butyric acid methyl ester. The sheet resistance of the MLG film on memory device was found to(More)
PURPOSE We compared bladder and urethral functions following radical prostatectomy (RP) between men with and without urinary incontinence (UI), using a large-scale database from SNU-experts-of-urodynamics-leading (SEOUL) Study Group. MATERIALS AND METHODS Since July 2004, we have prospectively collected data on urodynamics from 303 patients with lower(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)
To investigate whether diabetes mellitus (DM) was associated with postoperative outcomes, including prostate-specific antigen doubling time, among men who underwent radical prostatectomy (RP) for clinically localized prostate cancer (PCa). Data of 661 patients who underwent radical prostatectomy for node-negative prostate cancer and were followed up for ≥3(More)
Two-dimensional (2D) molybdenum disulphide (MoS2) atomic layers have a strong potential to be used as 2D electronic sensor components. However, intrinsic synthesis challenges have made this task difficult. In addition, the detection mechanisms for gas molecules are not fully understood. Here, we report a high-performance gas sensor constructed using(More)
PURPOSE The purpose of this article was to announce the establishment of the multicenter Korean Prostate Cancer Database (K-CaP) and to provide urologists with details about K-CaP's methodology. MATERIALS AND METHODS The initial participating K-CaP institutions include five medical centers in Korea. First, we registered prostate cancer patients who(More)
We investigated the enhanced photoresponse of ZnO nanowire transistors that was introduced with surface-roughness-induced traps by a simple chemical treatment with isopropyl alcohol (IPA). The enhanced photoresponse of IPA-treated ZnO nanowire devices is attributed to an increase in adsorbed oxygen on IPA-induced surface traps. The results of this study(More)
