BACKGROUND It is not known whether the primary tumour location of upper urinary tract urothelial carcinoma (UUT-UC) is associated with prognosis. OBJECTIVE To evaluate the impact of initial primary tumour location on survival in patients who had undergone radical nephroureterectomy (RNU). DESIGN, SETTING, AND PARTICIPANTS Using a multi-institutional,(More)
Emerging technologies, such as ultrasound (US), used for food and drink production often cause hazards for product safety. Classical quality control methods are inadequate to control these hazards. Hazard analysis of critical control points (HACCP) is the most secure and cost-effective method for controlling possible product contamination or(More)
According to the current upper urinary tract urothelial carcinomas (UTUC) guidelines, ureteroscopic evaluation (URS) is recommended to improve diagnostic accuracy and obtain a grade (by biopsy or cytology). However, URS may delay radical surgery [e.g., nephroureterectomy (RNU)]. The objective of this study was to evaluate the influence of URS implementation(More)
Prognostic impact of lymphadenectomy during radical nephroureterectomy (RNU) for urothelial carcinoma of the upper urinary tract (UTUC) is controversial. Our aim was to assess the impact of lymph node status (LNS) on survival in patients treated by RNU. In our multi-institutional, retrospective database, 714 patients with non-metastatic UTUC had undergone(More)
BACKGROUND The purpose of this study was to evaluate morbidity, functional, and oncological outcomes after NSS in renal tumors > 7 cm. MATERIALS AND METHODS We retrospectively analyzed data from 168 patients with tumors > 7 cm who were treated using NSS between 1998 and 2012. RESULTS Imperative and elective indications accounted for 76 (45.2%) and 92(More)
OBJECTIVE To assess if the presence of a lower pole stone (LPS) decreases the stone-free (SF) rate following retrograde intrarenal surgery (RIRS). The second purpose was to assess the result of RIRS for LPS and to identify predictors of SF status. PATIENTS AND METHODS We retrospectively analyzed 205 procedures in 162 patients with renal stones treated by(More)
ARTIcLE InfO ______________________________________________________________ ______________________ Objective: The aim of the study was to evaluate renal function and to identify factors associated with renal function deterioration after retrograde intrarenal surgery (RIRS) for kidney stones. Materials and Methods: We retrospectively analyzed patients with(More)
