OBJECTIVE To investigate the effect of spinal anesthesia (SA) vs general anesthesia (GA) administration on the safety and efficiency of percutaneous nephrolithotomy (PCNL). METHODS We retrospectively evaluated 1478 patients who underwent PCNL in our clinic between 2004 and 2011. We excluded the patients with bilateral PCNL, renal abnormality, or solitary(More)
PURPOSE In this multicenter study we aimed to evaluate the efficacy and safety of percutaneous nephrolithotomy in children with respect to different features and using the Clavien classification system. MATERIALS AND METHODS Percutaneous nephrolithotomies performed in children at 3 urology departments between March 2006 and May 2010 were included in the(More)
PURPOSE In this multicenter study we compared the outcome of percutaneous nephrolithotomy in patients with and without malrotated kidneys. MATERIALS AND METHODS A total of 44 patients (group 1) at 6 institutions who underwent percutaneous nephrolithotomy for kidneys with simple malrotation were enrolled in our study. Attending physicians in our group also(More)
PURPOSE We assessed factors affecting complication rates of percutaneous nephrolithotomy in children. MATERIALS AND METHODS We retrospectively evaluated data on 1,205 renal units in 1,157 children treated with percutaneous nephrolithotomy at 16 Turkish centers between 1991 and 2012. Of the patients 28.3% had a history of urolithiasis. Complications were(More)
OBJECTIVE We aimed to evaluate the efficacy and safety of percutaneous nephrolithotomy (PNL) in infants and small children (12-36 months). METHODS The PNL applications conducted in children <3 years of age in two centers were evaluated. Whereas pediatric PNL instrumentation was used in the first center, adult-size instrumentation was utilized in the(More)
PURPOSE To evaluate contemporary management approaches to medium-sized (10-20 mm) renal stones. PATIENTS AND METHODS A total of 935 patients treated for medium-sized renal stones (10-20 mm) between July 2012 and March 2014 were included in the study program. Contemporary minimally invasive approaches applied in the management of such stones were evaluated(More)
PURPOSE In this study, we present our experience using balloon and Amplatz dilatation to establish a percutaneous tract. We also discuss advantages and risk factors of both techniques. MATERIALS AND METHODS We retrospectively reviewed medical records of 229 patients who had undergone 235 percutaneous nephrolithotomy procedures. The nephrostomy tract had(More)
A 39-year-old man underwent percutaneous nephrolithotomy (PCNL) for bilateral renal stone without stent and tube insertion. To our knowledge, this is the first report of bilateral simultaneous tubeless and stentless PCNL. The advantage of this technique in renal stone surgery is discussed.
Nephrolithiasis management within an ectopic kidney presents a challenge to the urologists. Several treatment modalities are possible in this group of patients. Although percutaneous nephrolithotomy (PNL) is an accepted treatment modality in anatomically normal kidneys, ectopic pelvic kidneys require a different and more complicated approach for PNL. We(More)
