PURPOSE There is a lack of studies comparing shock wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and minimally invasive percutaneous nephrolithotomy (MIP) in renal stone treatment. This study compared treatment outcome, stone-free rate (SFR) and stone-free survival (SFS) with regard to stone size and localization. METHODS This analysis(More)
OBJECTIVES To evaluate the potential of (11)C-choline-positron emission tomography (PET)/computed tomography (CT) for planning surgery in patients with prostate cancer and prostate-specific antigen (PSA) relapse after treatment with curative intent. PATIENTS AND METHODS We retrospectively reviewed the charts of 10 patients with PSA recurrence after either(More)
PURPOSE To retrospectively evaluate radiation dose, image quality, and the ability to differentiate urinary calculi of differing compositions by using low-dose dual-energy computed tomography (CT). MATERIALS AND METHODS The institutional review board approved this retrospective study; informed consent was waived. A low-dose dual-energy CT protocol (tube(More)
OBJECTIVE To compare the safety and efficacy of minimally invasive percutaneous nephrolitholapaxy (MIP) between small (<2 cm) and large (>2 cm) renal calculi, because although MIP has proved its efficacy in small lower caliceal stones, the efficacy in large renal calculi has been questioned. MATERIALS AND METHODS The data from 191 consecutive minimally(More)
BACKGROUND The Adnatest® system combines immunomagnetic enrichment of epithelial cells with polymerase chain reaction for prostate cancer (PC)-specific transcripts for the detection circulating tumor cells (CTCs). We evaluated the Adnatest® in patients with castration-resistant PC receiving docetaxel chemotherapy. PATIENTS AND METHODS CTCs were assessed(More)
Heuristic concentration (HC) is a two-stage metaheuristic that can be applied to a wide variety of combinatorial problems. It is particularly suited to location problems in which the number of facilities is given in advance. In such settings, the ®rst stage of HC repeatedly applies some random-start interchange (or other) heuristic to produce a number of(More)
OBJECTIVES To evaluate characteristic imaging findings of tumor attenuation in multiphase computed tomography (CT) between renal oncocytomas and clear-cell renal cell carcinoma (ccRCC) of small tumor size (≤5 cm). METHODS We retrospectively identified 20 patients with complete four-phase CT with either histologically confirmed small renal oncocytoma(More)
