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)
Compared with the standard technique, the number of percutaneous nephrolithotomy (PCNL) operations without a drainage catheter is increasing in recent years. In this prospective randomized study, we compared the morbidity of totally tubeless (tubeless and stentless) PCNL operations with the standard operation technique in a single center with a selected(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)
Intrauterine devices (IUDs) are currently one of the most popular reversible contraception methods used world wide. Uterine perforation is a rarely observed complication. The bladder is one of the organs that an IUD can migrate to because of its close proximity to the uterus. There are about 70 cases in the literature of IUDs that have migrated into the(More)
AIM To evaluate the preoperative and intraoperative factors that might affect development of fever following percutaneous nephrolithotomy (PCNL) and to investigate the clinical significance of intraoperative microbiologic evaluation in managing postoperative infectious complications. PATIENTS AND METHODS Sixty-one consecutive patients who had undergone(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 We prospectively analyzed the outcome of tubeless percutaneous nephrolithotomies (PCNLs) using two different stenting techniques (i.e., externalized ureteral catheter compared with Double-J placement) without strict exclusion or inclusion criteria. PATIENTS AND METHODS Forty-six patients who were undergoing tubeless PCNL were randomized to two(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)
We investigated the effects of continuous lumbar traction in patients with lumbar disc herniation on clinical findings, and size of the herniated disc measured by computed tomography (CT). In this prospective, randomized, controlled study, 46 patients with lumbar disc herniation were included, and randomized into two groups as the traction group (24(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.
