PURPOSE Percutaneous nephrolithotomy has been the standard of care for intrarenal calculi greater than 2 cm. Flexible ureteroscopy with holmium laser lithotripsy is a minimally invasive treatment modality that is able to treat large intrarenal calculi with the potential to decrease morbidity, while maintaining a high level of efficacy. MATERIALS AND(More)
BACKGROUND External shock wave lithotripsy (ESWL) and percutaneous nephrolithotomy (PNL) have been the standard of care for the treatment of intrarenal calculi. OBJECTIVE We sought to determine the safety and efficacy of flexible ureteroscopy and holmium laser lithotripsy for the treatment of multiple intrarenal calculi and further stratify the efficacy(More)
OBJECTIVE To compare the last generation of 3-dimensional imaging (3D) vs standard 2-dimensional imaging (2D) laparoscopy. MATERIALS AND METHODS A prospective observational study was conducted during the 4th Minimally Invasive Urological Surgical Week Course held in Braga (Portugal) in April 2013. The course participants and faculty were asked to perform(More)
OBJECTIVES To test the sensitivity, specificity and accuracy of serum prostate-specific antigen isoform [-2]proPSA (p2PSA), %p2PSA and the prostate health index (PHI), in men with a family history of prostate cancer (PCa) undergoing prostate biopsy for suspected PCa. To evaluate the potential reduction in unnecessary biopsies and the characteristics of(More)
PURPOSE Despite standard treatment with transurethral resection (TUR) and adjuvant bacillus Calmette-Guérin (BCG), many high-risk bladder cancers (HRBCs) recur and some progress. Based on a review of the literature, we aimed to establish the optimal current approach for the early diagnosis and management of HRBC. METHODS A MEDLINE® search was conducted to(More)
INTRODUCTION Semirigid and flexible ureterorenoscopy (URS) procedures are safe and efficient treatment options for urolithiasis of all localizations. Sometimes, a Double-J stent is placed in preparation of definitive treatment. The aim of our study was to evaluate the influence of prestenting on the outcome of URS. PATIENTS AND METHODS We retrospectively(More)
CONTEXT The initial excitement about the laparoscopic treatment of renal masses has been tempered by concerns related to increased operative time, technical complexity, and the suitability of laparoscopic approaches to oncologic surgery. OBJECTIVE To provide a comprehensive review of intraoperative and postoperative complications and their prevention and(More)
Advancements in the endourological equipment have made retrograde intrarenal surgery (RIRS) an attractive, widespread technique, capable of competing with traditional shock wave lithotripsy and percutaneous nephrolithotomy. Since the complication rate is generally low, even less is known about dramatic and fatal complications after RIRS. We performed a(More)
OBJECTIVES Laparoscopic partial nephrectomy (LPN) is a technically challenging procedure for the management of renal tumours. Major complications of LPN include bleeding and urine leakage. Haemostatic agents (HAs) and/or glues may reduce haemorrhage and urine leakage. We sought to examine the current practice patterns for urologists performing LPN with(More)
Over the past 2 decades, a greater understanding of the basic biology and genetics of kidney cancer has occurred. Surgical techniques have also evolved, and technological advances have made possible new methods of managing renal tumors. The most extensively used system to provide prognostic information for renal cell carcinoma (RCC) is currently the tumor,(More)
