Giant renal calculus is rarely seen in urologic practice. A 69-year-old woman who had right giant renal calculus with poorly functioning opposite kidney is presented. She was with a history of right pyelolithotomy for large renal calculus 10 years back. Ultrasonography(USG), uncontrast computed tomography ( CT ), plain abdominal X-ray ( KUB ) and intraveneous urography ( IVU ) revealed a giant ...

A 66-year-old woman had a 22 mm right kidney stone accompanied with a horseshoe kidney. The size of this stone had been increasing gradually from 7 mm to 22 mm during the past 5 years. Although apparent pelviuretic junction stenosis could not be identified by intravenous urography, external pelvis was dilated in both kidneys. Complete excretion of fragmented stones by extracorporeal shockwave l...

PURPOSE A prototype ultrasound-based probe for use in ureteroscopy was used for in vitro measurements of stone fragments in a porcine kidney. METHODS Fifteen human stones consisting of three different compositions were placed deep in the collecting system of a porcine kidney. A 2 MHz, 1.2 mm (3.6F) needle hydrophone was used to send and receive ultrasound pulses for stone sizing. Calculated s...

Today large number of population suffers from kidney stone disease has increasing due to change in living conditions. Kidney stone formation or urolithiasis is a complex process that results from a succession of several physicochemical events including supersaturation, nucleation, growth, aggregation, and retention within the kidney. The treatments used are extracorporeal shock wave lithotripsy...

Background & Aims: Calcifying nanoparticles are different forms of calcium and phosphate in sediments. Recent evidence suggests that calcifying nanoparticles (CNPs) are probably selfreplicating. Several diseases are linked to nano-bacteria including kidney stones, gallbladder stone, cardiovascular plaques, oral–dental plaque, many cancers, and autoimmune diseases. The aim of this study was to a...

A variety of factors influence the formation of calcium oxalate kidney stones, including gender, diet, and urinary excretion of calcium, oxalate, and uric acid. Several of these factors may be related to body size. Because men on average have a larger body size and a threefold higher lifetime risk of stone formation than women, body size may be an important risk factor for calcium oxalate stone...

BACKGROUND Patients with medullary sponge kidney (MSK) commonly encounter recurrent nephrolithiasis. The existing knowledge on safety of donors with MSK has not been studied. METHODS We conducted a retrospective cohort study at a tertiary referral hospital to assess the outcomes of living kidney donors with MSK. All adults with MSK (N = 26) who underwent nephrectomy as living kidney donors be...

BACKGROUND The last nationally representative assessment of kidney stone prevalence in the United States occurred in 1994. After a 13-yr hiatus, the National Health and Nutrition Examination Survey (NHANES) reinitiated data collection regarding kidney stone history. OBJECTIVE Describe the current prevalence of stone disease in the United States, and identify factors associated with a history ...

Kidney diseases are one of the most common worldwide and cause unbearable pain in people. In this study aims to detecting cyst stone kidney. For purpose, YOLO architecture designs were used for detection kidney, kidney stone. The supported by explainable artificial intelligence (xAI) feature. CT images three classes, namely 72 cysts, 394 stones 192 healthy kidneys performance analysis part desi...

Kidney stone disease is endemic. Extracorporeal shockwave lithotripsy was the first major technological breakthrough where focused shockwaves were used to fragment stones in the kidney or ureter. The shockwaves induced the formation of cavitation bubbles, whose collapse released energy at the stone, and the energy fragmented the kidney stones into pieces small enough to be passed spontaneously....
