Background: Extracorporeal shockwave lithotripsy (SWL) is a procedure commonly performed to treat nephrolithiasis, with promising results in pediatric patients. However, increasing renal calculi size is directly related to worsening stone-free rates. There are few reports in the literature of >2-cm staghorn calculi that expound on the exact mechanism of treatment in the pediatric population. Case Presentation: We present a case report of a 3-year-old boy who presented with a large 3-cm staghorn calculi effectively treated with one session of SWL followed by a planned staged ureteroscopy for definitive treatment...

INTRODUCTION: Urolithiasis is a common medical condition that accounts for a large number of emergency department (ED) visits each year and contributes significantly to annual healthcare costs. Urinalysis is an important screening test for patients presenting with symptoms suspicious for urolithiasis. At present there is a paucity of medical literature examining the characteristics of ureteral stones in patients who have microscopic hematuria on urinalysis versus those who do not. The purpose of this study was to examine mean ureteral stone size and its relationship to the incidence of clinically significant hydronephrosis in patients with and without microscopic hematuria...

Urothelial carcinoma (Transitional cell carcinoma) of the bladder is the pre-dominant histological type of bladder cancer in the United States and Europe. Patients with bladder cancer usually present with painless hematuria. The diagnosis is often delayed, as the symptoms are similar to various other benign conditions such as urinary tract infection, prostatitis or renal calculi. In some patients, the metastatic lesions will cause the initial presenting symptoms. We conducted a MedLine/PubMED search identifying all relevant articles with "pulmonary manifestations", "urothelial bladder cancer", "manifestations of bladder cancer" or a combination of these terms in the title...

OBJECTIVES: Shock wave lithotripsy (SWL) remains the only effective truly non-invasive treatment for nephrolithiasis. While single-treatment success rates may not equal those of ureteroscopy and percutaneous nephrolithotomy, it has an important role to play in the management of stones. In this paper, we outline the latest evidence-based recommendations for maximizing SWL outcomes, while minimizing complications. MATERIALS AND METHODS: A comprehensive review of the current literature was performed regarding maximizing SWL outcomes...

Primary hyperoxaluria type 1 is an autosomal recessive hereditary glyoxylate metabolism disorder characterized by excessive production of oxalate, caused by the deficiency of liver specific peroxisomal enzyme: alanineglyoxylate aminotransferase. For patients with end-stage renal disease, combined liver and kidney transplantation was needed. This report describes one patient, with a diagnosis of end-stage renal disease and primary hyperoxaluria 1 confirmed by PCR and direct sequencing with genomic DNA, received the simultaneous combined liver and kidney transplantation after seven months' waiting...

Afferent loop syndrome (ALS) is a rare complication of Billroth-II gastrojejunostomy. Causes of afferent loop obstruction include adhesions, internal hernias, intestinal strictures or malignancy. Obstruction caused by enteroliths is rare and usually requires surgery. We present the case of a 90-year-old man with a Billroth-II performed 50 years earlier and three acute pancreatitis. He presented with acute abdominal pain, without signs of pancreatitis. Upper digestive endoscopy revealed a punctiform anastomotic stricture of the afferent loop...

Recently, cases of urinary tract calculi causing hydronephrosis and postrenal renal failure associated with viral gastroenteritis were documented, yet few were related to norovirus. During norovirus gastroenteritis, observation of oliguria, aciduria, low FENa value, and elevation of blood or urinary uric acid level may necessitate clinical workout for nephrolithiasis.

Cystinuria is caused by defective proximal renal tubular reabsorption of the amino acids cystine, ornithine, lysine, and arginine (COLA). The low solubility of cystine in mildly acidic urine may lead to the formation of urinary cystine crystals and uroliths. Much progress has been made recently in the diagnosis and understanding of cystinuria in companion animals. In cats, cystinuria affects equally both genders independent of neutering status and, despite being rare, already more cystinuria-causing mutations have been detected in cats compared to dogs...
