Geriatric Assessment Can Predict Outcomes of Endoscopic Surgery for Benign Prostatic Hyperplasia in Elderly Patients.

Unlabelled: Ojectives: Surgical management of benign prostatic hyperplasia (BPH) in elderly patients is associated with higher morbidity and mortality rate. This raises the question of benefice and risk balance. We conducted a prospective observational study to evaluate the results of endoscopic surgery for BPH in elderly patients, according to geriatric assessment.

Impact of retrograde flexible ureteroscopy and intracorporeal lithotripsy on kidney functional outcomes.

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 renal stones treated by RIRS between January 2010 and June 2013 at a single institute. We used the National Kidney Foundation classification of chronic kidney disease (CKD) to classify Glomerular Filtration Rate (GFR) in 5 groups.

Nephron-sparing surgery for renal tumors measuring more than 7 cm: morbidity, and functional and oncological outcomes.

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.

Impact of lower pole calculi in patients undergoing retrograde intrarenal surgery.

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 RIRS between January 2010 and January 2013 at a single institute.

The impact of lymph node status and features on oncological outcomes in urothelial carcinoma of the upper urinary tract (UTUC) treated by nephroureterectomy.

Purpose: 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.

Methods: In our multi-institutional, retrospective database, 714 patients with non-metastatic UTUC had undergone RNU between 1995 and 2010.

The oncologic impact of a delay between diagnosis and radical nephroureterectomy due to diagnostic ureteroscopy in upper urinary tract urothelial carcinomas: results from a large collaborative database.

Objectives: 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.

Ureteral and multifocal tumours have worse prognosis than renal pelvic tumours in urothelial carcinoma of the upper urinary tract treated by nephroureterectomy.

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, retrospective database, we identified 609 patients with UUT-UC who had undergone RNU between 1995 and 2010.

Hazard analysis and critical control point (HACCP) for an ultrasound food processing operation.

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 cross-contamination, due to physical or chemical hazard during production.
