Renal stone formation (nephrolithiasis) is a worldwide problem causing substantial morbidity and economic burden. The heritability of stone formation has long been recognized, and with the advent of the genomic era, we have the potential to define the underlying genetic defects. Renal stone formation is multifactorial, with environmental factors interacting with underlying genetic factors. Isol...

We present a case of renal stone associated with bilateral pelvic diverticula. The initial diagnosis by ultrasonography and plain abdomen radiography (KUB) was urolithiasis with a 15-mm calculus in the right renal pelvis. The patient was referred for extracorporeal shock wave lithotripsy, but no stone fragments were yielded. So, further evaluations were performed by using repeated ultrasonograp...

BACKGROUND We have biopsied the renal cortex and papillae of patients who form brushite renal stones asking if this unusual stone type is associated with specific tissue changes. We contrasted these with biopsies of 15 calcium oxalate stone formers, three stone formers with intestinal bypass, and four normal subjects. METHODS We studied all ten brushite stone formers treated with percutaneous...

INTRODUCTION We have previously described the use of ureteroscopy-assisted retrograde nephrostomy. However, reaching the target calyx with the ureteroscope is difficult in patients with obstructive renal pelvic stones. CASE PRESENTATION A 53-year-old Japanese woman was referred to our department for the treatment of a right renal stone. She was admitted to our department for percutaneous neph...

PURPOSE To determine the predictive value of certain radiological parameters for an objective asssessment of the presence of ureteral stone impaction. MATERIALS AND METHODS Seventy-nine patients with a single proximal ureteral stones were retrieved from the departmental database. Both clinical and particularly radiological data of all cases were well evaluated on this aspect. In addition to t...

Objective. To evaluate the clinical outcome of flexible ureterorenoscopy (F-URS) with holmium laser in managing renal stone greater than 2 cm. Patients and Methods. Records of 120 patients (123 renal units) with renal stone greater than 2 cm who underwent F-URS with holmium laser iwere evaluated. The mean stone size was 26.3 mm. Patient and stone characteristics, perioperative outcomes and comp...

BACKGROUND AND PURPOSE Renal calculous disease may be associated with various degrees of renal insufficiency secondary to a combination of obstruction, urinary infection, frequent surgical intervention, and coexisting medical disease. Herein, we present our data on the progression of renal function in patients with stones associated with renal insufficiency and assess the significance of variou...

We report a case of a kidney-transplanted patient with urolithiasis treated with mini-percutaneous laser lithotripsy. The patient presented with renal dysfunction and graft hydronephrosis. Diagnostic procedures revealed ureterolithiasis as a cause of obstruction, and percutaneous nephrostomy was inserted as a temporary solution. Before surgery, the stone migrated to the renal pelvis. Mini-percu...

AIMS To evaluate renal morphology, prevalence of urinary stone disease, renal perfusion and resistance to renal blood flow in patients with ankylosing spondylitis(AS). MATERIAL AND METHODS Thirty-eight patients diagnosed with AS and with normal basal renal functions, together with 38 healthy individuals matched in terms of age, sex, blood lipid profile and body mass index, were included. Tota...
