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 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 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)
Osteogenesis imperfecta (OI) patients represent a challenge to all physicians, as they do for anesthetists and urologists, when they develop symptomatic stones in the urinary tract. We recently treated an OI patient with renal pelvic stone by extraperitoneal laparoscopy-assisted percutaneous nephrolithotomy (PCNL). To our knowledge, this combined treatment(More)
OBJECTIVE We aimed to present the technique of combination of standard percutaneous nephrolithotomy (PNL) with microperc for achieving higher success rates without increasing complication rates in the management of complex renal calculi. MATERIAL AND METHODS The patients who underwent microperc procedure as a complementary procedure to standard PNL for(More)
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)
INTRODUCTION Ureteroscopic pneumatic lithotripsy has been used to treat ureteral calculi for more than 10 years. Owing to its low price and high degree of effectiveness, it has become the most popular ureteroscopic lithotripsy device in use worldwide. The major limitation of the technique is the occurrence of proximal fragment migration during(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)
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)
