A case of neonatal renal oxalosis in a 7-day-old calf is described. Clinical biochemistry revealed increased blood urea nitrogen. Gross findings included thin renal medulla and dilated renal calyces containing numerous, small, pale yellow and granular calculi. Histologically, most cortical and medullary tubules were dilated with birefringent crystals, whereas the glomeruli appeared unaffected. ...

*E-mail: [email protected] We report a rare case of an ectopically placed ureteral stent, which was acceptable and functional. obstructing 8 × 15-mm proximal right-sided ureteral calculus. There were also multiple nonobstructing renal calculi on the left side. An antegrade ureteral stent was placed to relieve his infected and obstructed right kidney. During stent placement, the interventional ra...

BACKGROUND Melamine is an industrial chemical used primarily as plastics stabilizer and fire retardant. On September 11, 2008, melamine-contaminated milk products were reported to be responsible for urinary tract calculi in infants and children in China. This study aimed to investigate the prevalence, lesions, risk factors, clinical features, and management of children fed with the melamine-con...

We present a clinical case of a 66-year-old female with a left ureteropelvic junction impacted renal calculi associated with a tortuous ureter. After a failed combined retrograde and antegrade endoscopic procedure, a robot-assisted laparoscopic ureteropyelostomy was successful.

BACKGROUND Since the outbreak of renal diseases among children who had consumed melamine-tainted powdered formula in 2008, urinary system ultrasound examination was carried out for these children at our hospital. This study aimed to investigate the ultrasonographic characteristics of urolithiasis caused by melamine-tainted powdered formula. METHODS From September 12 to October 9, 2008, urinar...

OBJECTIVE To determine the efficacy and safety of high-power holmium: yttrium aluminum-garnet (Ho:YAG) laser lithotripsy for multitract modified minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of patients with large staghorn renal calculi. METHODS A randomized, prospective study was conducted. Two-hundred seventy-three consecutive patients (291 renal units) with large...

BACKGROUND AND OBJECTIVES Nephrolithiasis (LIT) is more prevalent in patients with autosomal dominant polycystic kidney disease (ADPKD) than in the general population. Renal ultrasonography may underdetect renal stones because of difficulties imposed by parenchymal and/or cyst wall calcifications. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A total of 125 patients with ADPKD underwent ultra...

The incidence of renal abscesses is not common. Patients usually have risk factors like diabetes mellitus or an underlying condition which predisposes to urinary tract infections. We report a case of a previously healthy young girl with multiple bilateral renal abscesses. Ultrasonography revealed multiple renal abscesses with a possible differential diagnosis of polycystic kidney disease with i...

Introduction: Pakistan is situated in the Afro-Asian stone belt. We come across a vast majority of patients having renal calculi. The treatment stones has evolved from open surgery to extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL) and retrograde intrarenal (RIRS) past 20 years. Objective: To determine mean skin distance (SSD) undergoing ESWL for pelvic compare...
