OBJECTIVES To evaluate the effect of alfuzosin in improving symptoms in, and quality of life of, patients with indwelling double-J ureteral stents. METHODS A total of 100 patients, 50 men and 50 women (mean age 54.2 years), with unilateral ureteral stone-related hydronephrosis, who had opted for conservative management with insertion of a double-J(More)
BACKGROUND Accurate prediction of outcome for metastatic renal cell carcinoma (mRCC) patients receiving targeted therapy is essential. Most of the available models have been developed in patients treated with cytokines, while most of them are fairly complex, including at least five factors. We developed and externally validated a simple model for overall(More)
INTRODUCTION Impacted stones are those that remain unchanged in the same location for at least 2 months. MATERIALS AND METHODS We evaluated 42 patients with impacted ureteral stones, and followed them for two and a half years to check for long-term results. The calculi location included all three segments of the ureter (proximal, mid and distal).(More)
OBJECTIVES To evaluate the efficacy and safety of the type of urinary diversion during radical cystectomy in high-risk elderly patients by comparing a modified cutaneous ureterostomy with the ileal conduit urinary diversion. METHODS Of 481 patients who underwent radical cystectomy between 1993 and 2002, 54 individuals older than 75 years with an American(More)
OBJECTIVE We evaluated safety and efficacy of first-line gemcitabine/carboplatin in unfit-for-cisplatin patients with advanced urothelial carcinoma and the effect on the quality of life and functional status of elderly patients (aged >70). METHODS Unfit patients had ECOG performance status (PS) > or =2, creatinine clearance <50 ml/min or comorbidities(More)
INTRODUCTION Early risk assessment is the mainstay of management of patients with sepsis. APACHE II is the gold standard prognostic stratification system. A prediction rule that aimed to improve prognostication by APACHE II with the application of serum suPAR (soluble urokinase plasminogen activator receptor) is developed. METHODS A prospective study(More)
This study explores the role of procalcitonin (PCT) in predicting the outcome of sepsis. In a prospective multicentre observational investigation, blood was sampled within 24 h of onset of sepsis in 1156 hospitalised patients; 234 were in the intensive care unit (ICU) at the point of presentation of sepsis while 922 were not. PCT was estimated in serum by(More)
Our objective was to compare the effect of tamsulosin versus transurethral resection of the prostate (TURP) for the management of nocturia in previously untreated men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) and no other predisposing factors for nocturia. The study group included 66 patients (mean age 68.9(More)
OBJECTIVES To assess the efficacy and safety of nonsteroidal anti-inflammatory drugs (NSAIDs) administered after radical retropubic prostatectomy (RRP). METHODS One hundred patients undergoing open RRP by one surgeon were divided randomly and prospectively into two groups of 50 patients, each receiving systematically either an NSAID (lornoxicam) or(More)
BACKGROUND Current knowledge on the exact ligand causing expression of TREM-1 on neutrophils and monocytes is limited. The present study aimed at the role of underlying infection and of the causative pathogen in the expression of TREM-1 in sepsis. METHODS Peripheral venous blood was sampled from 125 patients with sepsis and 88 with severe sepsis/septic(More)
