Undoubtedly, humans have been analyzing the effectiveness of locational decisions since they inhabited their first cave. We use the term “facility” here in its broadest sense. That is, it is meant to include entities such as air and maritime ports, factories, warehouses, retail outlets, schools, hospitals, day-care centers, bus stops, subway stations,(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)
UNLABELLED What's known on the subject? and What does the study add? There is increasing evidence for a prognostic significance of pretherapeutically elevated serum C-reactive protein levels in various cancers. However, little is known about its significance in patients with invasive bladder cancer. This study shows that serum CRP is an independent(More)
OBJECTIVES Pelvic lymph node metastases indicate a poor prognosis for prostate cancer patients. The aim of this study was to evaluate the suitability of laparoscopic radioisotope guided sentinel lymph node (SLN) dissection in staging of prostate carcinoma. METHODS 28 patients with prostate cancer and intermediate or high risk for lymph node metastases(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)
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. This analysis included 482(More)
OBJECTIVES In dual energy (DE) computed tomography (CT), spectral shaping by additional filtration of the high energy spectrum can theoretically improve dual energy contrast. The aim of this in vitro study was to examine the influence of an additional tin filter for the differentiation of human urinary calculi by dual energy CT. MATERIALS AND METHODS A(More)
OBJECTIVE To evaluate the accuracy of high-spatial resolution T2-weighted endorectal magnetic resonance imaging (eMRI) for detection and pattern depiction of seminal vesicle invasion (SVI) in patients with prostate cancer (PCa). METHODS 376 patients were included who underwent eMRI for staging before radical open prostatectomy at 1.5 T with an endorectal(More)
OBJECTIVES To investigate the outcomes using gelatine matrix hemostatic sealant to close the tract after mini-percutaneous nephrolithotomy (mini-PCNL), resulting in a tubeless setting. METHODS After complete stone removal after mini-PCNL, a double-J ureteral stent was placed in an antegrade manner. After withdrawing the 17F Amplatz sheet from the(More)
