In emerging economies, electronic waste is an important problem, because it negatively affects the health of staff and people, and causes pollution. Moreover, the location of the collection center has a crucial role in sustainable supply chains. Therefore, in this study, a framework was proposed to identify the location of sustainable collection centers for e-waste.

Material And Methods: We performed 159 consecutive radical nephrectomy between December 2007 and January 2014. We evaluated age, gender, complaints, operation time, comorbidity, computed tomography (CT) and magnetic resonance graphy (MRG) results.
Objective: Shock-wave lithotripsy (SWL) is the first-line treatment for the active removal of small and medium-sized kidney stones. Flexible ureterorenoscopy (fURS) is recommended after failed SWL treatment. The aim of this retrospective analysis is to evaluate whether prior unsuccessful SWL treatments affect the outcomes of fURS.

Patients And Methods: Data of patients who underwent f-URS between January 2009 and December 2012 were collected. Patients were staged according to estimated glomerular filtration rate.
Introduction And Objectives: To compare the outcomes of these minimally invasive procedures in this patient population.
Patients And Methods: The database of our institution has been retrospectively reviewed, and medical records of urolithiasis patients with a solitary kidney who underwent flexible ureteroscopy (F-URS) or extracorporeal shock wave lithotripsy (SWL) between January 2009 and December 2012 were examined. Retreatment rates, complications, changes in estimated glomerular filtration rates (eGFRs), chronic kidney disease (CKD) stages, and stone-free rates were compared between the two groups.
The characteristics of clinically insignificant residual fragments (CIRFs) are well described after percutaneous nephrolithonomy (PCNL) and shock wave lithotripsy (SWL). In follow-up procedures, CIRFs are associated with obstruction, infectious conditions, and recurrent stone development. In this study, we aim to determine the medium-term outcomes of CIRF.

At this point, we believed that pelvicaliceal system type may play a significant role on stone clearance. In our study, we aimed to investigate the effect of pelvicaliceal system type on PNL outcomes.

Patients And Methods: Between February 2010 and March 2011, a total of 198 patients in whom PCNL was performed were prospectively randomized into two main groups regarding the type of prophylactic antibiotic (group1: sulbactam-ampicillin, group 2: cefuroxime). Each group was further randomized according to duration of antibiotic maintenance (a: single dose prophylaxis, b: additional dose 12 hours after prophylaxis, c: beginning with prophylactic dose until the nephrostomy tube removal).
Purpose: There are few studies of the long-term outcome of percutaneous nephrolithotomy for staghorn calculi. We report the long-term outcome of percutaneous nephrolithotomy in patients with staghorn calculi.
Material And Methods: A total of 265 study patients (272 renal units) were followed in the long term for greater than 12 months.
The components of metabolic syndrome, such as obesity, hypertension, and diabetes, are thought to be associated with urolithiasis. However, there are few large-scale studies that have examined the association between metabolic syndrome and urolithiasis, which prompted us to study and evaluate the relationship between metabolic syndrome components and urolithiasis in a nationwide survey, using the cross-sectional study conducted by a professional investigation company, with 2,468 enrolled participants, aged between 18 and 70 years, from 33 provinces in Turkey. Participants were interviewed face-to-face by medical faculty students.
View Article and Find Full Text PDFPurpose: We evaluated the long-term outcomes of percutaneous nephrolithotomy in patients with chronic kidney disease.
Materials And Methods: Data on 1,904 patients who underwent percutaneous nephrolithotomy between 2002 and 2011 were retrospectively collected. The estimated glomerular filtration rate for each patient was retrospectively calculated using a 4-variable modification of diet in renal disease equation.
Objective: To investigate the effect of the pelvicaliceal system (PCS) anatomy on the percutaneous nephrolithotomy (PCNL) success rate. Although the caliceal anatomy is effective for stone clearance after shock wave lithotripsy and retrograde intrarenal lithotripsy, the effect of the caliceal anatomy after PCNL has not been evaluated to date.
Methods: A total of 498 patients who had undergone PCNL and preoperative intravenous urography were enrolled in our study.
Objectives: To evaluate the outcomes, complications, and early and late postoperative kidney function of percutaneous nephrolithotomy (PCNL) in patients with solitary kidneys.
Methods: Between 2002 and 2009, 47 patients with a solitary kidney (congenital in 10 patients, 21.3%; contralateral nephrectomy in 22 patients, 46.
Purpose: We aimed to compare the outcomes of patients who were treated using digital and fiberoptic flexible ureterorenoscopy (urs) for kidney stones.
Patients And Methods: Between September 2008 and December 2009, a total of 76 patients who were treated with either a conventional fiberoptic flexible ureterorenoscope (FFU) (n = 34) or digital flexible ureterorenoscope (DFU) (n = 42) were compared. All procedures were performed by the same surgeon.
Objectives: To evaluate the effects of kidney stones and patient-related parameters on the length of hospitalization (LOH), which is one important factor affecting the cost effectiveness of percutaneous nephrolithotomy (PCNL). Recently, increases in healthcare costs have highlighted the importance of evaluating the cost effectiveness of a treatment as much as its efficacy.
Material And Method: During an 8-year period, the records of 1669 patients with renal calculi who underwent PCNL were reviewed retrospectively.
Objectives: A classification (modified Clavien system) has been proposed to grade perioperative complications. We reviewed our experience with percutaneous nephrolithotomy (PNL), grading the complications according to this new classification.
Methods: A total of 811 PNLs were performed between 2003 and 2006, and charts were retrospectively reviewed focusing on complications observed.
Objectives: Percutaneous nephrolithotomy (PNL) is sometimes associated with complications, especially in patients with complex stones. Herein, we review our experience with PNL to determine the impact of percutaneous access number and location on success and complication rates.
Patients And Methods: During a 2-year period, a total of 275 patients with a mean age of 42.
Aim: Improvements in extracorporeal shock wave lithotripsy (ESWL) and ureteroscopy have almost eradicated the need for open surgery in ureteral stones. The aim of this study was to assess characteristics of patients who underwent open ureterolithotomy.
Methods: During a 5-year period, a total of 654 patients with ureteral stones were treated.
