OBJECTIVES To critically review the current scientific evidence about open partial nephrectomy (OPN) and laparoscopic partial nephrectomy (LPN) to define the current role of these techniques in the treatment of renal tumours. METHODS PubMed and Medline were searched for reports about OPN and LPN that were published from 1990 to 2007 and the most relevant(More)
OBJECTIVES To assess the clinical role of corticosteroids in the medical expulsive therapy of symptomatic distal ureteral stones. METHODS Between January 2004 and September 2005, 114 patients with symptomatic distal ureteral stones with a >/=5mm diameter were enrolled in this prospective study and divided into four groups based on the urologist (of four)(More)
PURPOSE We assessed chromogranin A as a tissue biomarker in prostate needle biopsies or as a plasma biomarker, a risk factor for hormone refractory prostate cancer. MATERIALS AND METHODS A total of 211 patients with newly diagnosed prostate cancer treated with luteinizing hormone releasing hormone analogues constituted the study cohort. Univariate and(More)
BACKGROUND Retroperitoneal fibrosis (RF) is a complex clinical entity characterized by a fibro-inflammatory reaction around the abdominal aorta and iliac arteries extended into the retroperitoneum. No biochemical marker correlates with the disease severity and progression, and imaging data fail to discriminate between fibrotic and florid lesions. Positron(More)
OBJECTIVE To demonstrate the safety of the Millin extraperitoneal laparoscopic adenomectomy by comparing the laparoscopic and open approaches. METHODS From January 2003 to April 2005, patients, with indication of prostatic adenomectomy, were offered the chance to choose between 2 types of procedure: Millin adenomectomy with open or extraperitoneal(More)
OBJECTIVES The prognostic role of the invasion of the urinary collecting system (UCS) by renal cell carcinoma (RCC) has not attracted a notable amount of attention. The aim of this study was to investigate incidence and prognostic value of UCS involvement in RCC. MATERIAL AND METHODS All pathological reports of radical nephrectomies performed in two(More)
OBJECTIVES This study sought to show the effectiveness and safety of three repeated alcohol injections for the treatment of simple large renal cysts. METHODS From September 1991 to December 1997 we treated 72 renal cysts. The cyst was drained with an 8F mono J stent. Ninety-five percent sterile ethanol was injected into the cyst and left in place for 20(More)
BACKGROUND AND PURPOSE Laparoscopic radical cystectomy is confined to centers where advanced laparoscopy is performed, and its role is not yet well clear. Our aim was to evaluate, through a prospective comparative study, the advantages of the laparoscopic compared with an open approach. PATIENTS AND METHODS From November 2002 to December 2005, all the(More)
OBJECTIVE The most commonly used staging system for renal cell carcinoma (RCC) is the tumor-node-metastasis (TNM) system. In the most recent TNM edition, lymph node (LN) involvement is defined as pN0, pN1, or pN2, depending on the number of metastatic LNs (none, 1, or >1). This study evaluated the prognostic value of this classification and tried to improve(More)
