A Filter method is introduced in this paper for efficient speckle suppression and detection of calculi in sonographic images of the kidney.Wavelets are developed in applied mathematics for the analysis of multiscale image structures. The aim of this project is to analysesand to provide most significant content descriptive parameters to identify and classify the kidney stones with ultrasound sca...

Management of large calculi in ectopic pelvic kidneys poses a challenge to the urologist. Risk of injury to surrounding abdominal viscera and vasculature makes open surgery as well as percutaneous nephrostolithotomy in an ectopic kidney a challenging procedure. Laparoscopic management avoids open surgery and associated morbidity and offers added safety. We report the management of symptomatic s...

At least 10% of adults and nearly all children who receive renal-replacement therapy have an inherited kidney disease. These patients rarely die when their disease progresses and can remain alive for many years because of advances in organ-replacement therapy. However, these disorders substantially decrease their quality of life and have a large effect on health-care systems. Since the kidneys ...

A 50-year-old woman presented with a 2-years history of chronic flanc and hematuria. Plain abdominal radiography was performed showing bilateral complete staghorn calculi. Urinalysis and urine culture revealed a urinary infection by Proteus Morganii. Biologic investigations did not show any matabolic disorder. The urinary infection was treated by antibiotics and the stone by a combination of pe...

OBJECTIVES To evaluate patterns of laterality in cystine stone formation to determine whether phenotypic expression of this genetic disease is distributed equally in each kidney. Cystinuria is a genetic defect that may result in the formation of recurrent cystine calculi. Significant nongenetic factors may play a role in the manifestation of this disease. METHODS Thirty-four patients seen in ...

conclusions when evaluating flank pain in patients, it is important to remember that cbc parameters may support urinary stone disease, and considering cbc results may be useful in the diagnosis of urinary stone disease. patients and methods this study was a retrospective observational study of 3,099 patients who were admitted to the urology outpatient clinic or diagnosed with urinary stone dise...

INTRODUCTION Horseshoe kidney is the most common fusion abnormality in the kidney and occurs in 1 per 400 people with the male female ratio of 2:1.(1) Duplication of renal collecting system is the most common upper tract anomaly with an incidence of 0.5-0.8%.(2) Unilateral duplication is six times more frequent than bilateral duplication, with equal incidence on right and left sides.(3) However...

X-ray powder diffraction was used to study the phase composition of human renal calculi. The stones were collected from 56 donors in Vitória, Espírito Santo state, southeastern Brazil. An XRD phase quantification revealed that 61% of the studied renal stones were composed exclusively of calcium oxalate 34% formed only by calcium oxalate monohydrate COM and 27% presents both monohydrate and dihy...

Aim: To present our initial experience of applying laparoendoscopic single-site surgery (LESS) nephrolithotomy in the treatment of renal calculi. Methods: In August 2010 and April 2012, the LESS nephrolithotomy technique was applied to treat two patients with a renal calculus. One patient had a calculus measuring 5 × 3 cm, and the second patient’s measured 3 × 3 cm. Both patients underwent gene...
