OBJECTIVE: To evaluate the effect of percutaneous access site on the success and complication rates of isolated calyceal stones. MATERIAL AND METHODS: We retrospectively evaluated 2700 patients who underwent percutaneous nephrolithotomy (PNL) in our clinic between October 2002 and August 2014. We selected only the patients with isolated lower, middle or upper calyceal stones and we grouped the patients according to the location of their stones. Successful operation was defined as complete stone clearence or retention of stone fragments smaller than 4 mm which do not lead to infection, obstruct...

In this study, we aim to evaluate the effectiveness and safety of PNL in patients with a history of open renal surgery or PNL by comparing with primary patients and to compare impact of previous open renal surgery and PNL on the success and complications of subsequent PNL. Charts of patients, who underwent PNL at our institute, were analyzed retrospectively. Patients were divided into three groups according to history of renal stone surgery. Patients without history of renal surgery were enrolled into Group 1. Other patients with previous PNL and previous open surgery were categorized as Group...

We report a case of a 37-year-old man with a body mass index of 28 kg/m(2) who presented to our outpatient clinic with intermittent left flank pain. Non-contrast abdominopelvic computed tomography revealed a giant coralliform calculus in the left kidney. This giant kidney stone was successfully treated with 3 sessions of percutaneous nephrolithotomy (PNL) with a total 12 accesses. There was no significant reduction in the split function of the kidney after PNL.

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 tw...

Due to the presence of structural and anatomical differences that accompany anomalous kidneys, currently available endourological modalities such as SWL and PNL may be insufficient, or additional laparoscopic assistance may be required. The present study aims to evaluate the efficacy and safety of retrograde flexible ureterorenoscopic stone treatment in patients with kidney anomalies. Over the last 3 years, 25 patients with renal stones in anomalous kidneys were consecutively treated by flexible ureterorenoscopy and holmium:YAG laser lithotripsy. Among the 25 patients, fiberoptic or digital fl...
