OBJECTIVES To determine the chemical composition of pure and mixed urinary calculi by multislice helical computed tomography (CT) in an in vitro setting. CT is becoming the preferred radiologic examination in diagnosis and management of calculus disease. The management of calculus disease can be facilitated by ascertaining the stone composition. Unnecessary(More)
AIM We aimed to examine whether there is any association between serum levels of 25-hydroxyvitamin D [25(OH)D3] and urinary tract infection (UTI) among children. METHODS White blood cell count, serum C-reactive protein, calcium, phosphorus, alkaline phosphatase, parathormone, and serum 25(OH)D3 levels were measured in 82 children experiencing a first(More)
BACKGROUND The aim of the present study was to assess the possible etiologic role of human papillomaviruses (HPV) in bladder tumors. METHODS Forty-two fresh biopsy specimens from different grades and stages of bladder tumor cases and 10 normal bladder mucosa biopsies were studied. Specimens were analyzed by polymerase chain reaction (PCR) with(More)
PURPOSE To review the treatment efficacy and to assess the complications encountered in patients with single renal or ureteral calculi managed with a new-generation SWL machine, the Siemens Lithostar Modularis Uro-Plus. PATIENTS AND METHODS The stone location, size, minimum and maximum energy used, localization technique, number of shockwaves, fluoroscopy(More)
OBJECTIVES To evaluate the effectiveness of ureteral Dacron-covered metallic stents in the management of malignant ureteral obstruction. METHODS Covered metallic stents were placed unilaterally using a percutaneous approach in an antegrade fashion into nine ureters of 8 patients with bilateral malignant ureteral obstruction. The contralateral kidneys were(More)
A 35-year-old woman who underwent partial nephrectomy had prolonged postsurgical urinary extravasation that led to a percutaneous fistula. A double-J catheter used as a ureteral stent during surgery was in place. A percutaneous pigtail nephrostomy was inserted on the 15th postoperative day but drainage continued. Antegrade pyelography demonstrated(More)
Bladder stones occasionally develop because of foreign bodies in the bladder. Bladder stones in a 30-year-old woman were found to have formed around an intrauterine contraceptive device that had gone missing many years previously and had migrated into the bladder. Plain abdominal radiograms should be a part of the evaluation in patients with a history of an(More)
BACKGROUND Urinary tract infection (UTI) is common in children. The aim of this study was therefor to construct a guide for the empirical antibiotic treatment of community-acquired UTI by investigating the etiology and antimicrobial resistance patterns of uropathogens and analyzing the epidemiological and clinical patient characteristics. METHODS A total(More)
BACKGROUND Acute pyelonephritis (APN) can lead to renal scar formation, high blood pressure, and end-stage renal failure. Prompt and early diagnosis of APN is important for preventing future complications. Our goal was to study the mean platelet volume (MPV) as a predictor of APN in children. METHODS The records of 43 patients with APN and 51 patients(More)
Neurofibromatosis, or von Recklinghausen's disease, is an autosomal dominant disease with multiple neurofibroma and café-au-lait spots. However, neurofibroma in the bladder wall is a rare condition in von Recklinghausen's disease. A 31-year-old man with neurogenic voiding dysfunction due to sacral meningocele and acute urinary retention with neurofibroma of(More)
