PURPOSE We evaluate the incidence and risk factors of parastomal hernia formation in patients undergoing radical cystectomy and ileal conduit urinary diversion. MATERIALS AND METHODS We retrospectively reviewed the Indiana University cystectomy database between 2001 and 2011, and identified 516 patients who underwent radical cystectomy and ileal conduit(More)
PURPOSE We examined outcomes in patients with recurrent or de novo renal lesions treated with repeat partial nephrectomy on a solitary kidney. MATERIALS AND METHODS We reviewed the records of patients who underwent nephron sparing surgery at the National Cancer Institute from 1989 to 2008. Patients were included in analysis if they underwent repeat(More)
BACKGROUND Estimation of ventricular volume and mass is important for baseline and serial evaluation of fetuses with normal or abnormal hearts. Direct measurement of chamber wall volumes and mass can be made without geometric assumptions by 3D fetal echocardiography. Our goals were to determine the feasibility of using fast nongated 3D echocardiography for(More)
PURPOSE Previous studies have shown that ischemia alters gene expression in normal and malignant tissues. There are no studies that evaluated effects of ischemia in renal tumors. This study examines the impact of ischemia and tissue procurement conditions on RNA integrity and gene expression in renal cell carcinoma. EXPERIMENTAL DESIGN Ten renal tumors(More)
OBJECTIVE This study was designed to validate a slow-sweep real-time 4-dimensional (4D) spatiotemporal image correlation method for producing quantitatively accurate dynamic fetal heart images using an in vitro pulsatile balloon model and apparatus. METHODS To model fetal heart chambers, asymmetric double-walled finger stalls (tips of surgical latex(More)
Arrays of ideally ordered alumina nanochannels with unprecedented ,10 nm pore size, 40–50 nm interpore spacing, and improved channel uniformity have been fabricated by anodizing an aluminum substrate with a guiding pattern on its surface. The pattern is an array of hexagonally close-packed concaves fabricated by focused ion beam direct sputtering; and its(More)
INTRODUCTION This study seeks to evaluate the incidence and associated risk factors of Clostridium difficile infection (CDI) in patients undergoing radical cystectomy (RC) for bladder cancer. METHODS We retrospectively reviewed a single institution׳s bladder cancer database including all patients who underwent RC between 2010 and 2013. CDI was diagnosed(More)
OBJECTIVE To evaluate the oncologic outcomes of patients with retroperitoneal teratoma only at primary retroperitoneal lymph node dissection (RPLND) who did not receive adjuvant chemotherapy. MATERIALS AND METHODS Between 1979 and 2010, 23 patients with clinical stage (CS) I and II disease underwent primary RPLND at our institution with teratoma only in(More)
PURPOSE We examined the impact of positive vascular margins in patients with pT3 clear cell renal cell carcinoma. MATERIALS AND METHODS After excluding patients with nonvascular positive margins, metastasis, lymph node involvement, neoadjuvant therapy or nonclear cell histology, we identified 224 patients with venous tumor invasion through our(More)
