OBJECTIVE To present our experience in minimally invasive management of urinary tract stones in patients with urinary diversion. MATERIALS AND METHODS We retrospectively reviewed 26 patients with urinary tract stones after cystectomy and urinary diversion. The types of urinary diversion were ileal conduit, colon conduit, ileal orthotopic neobladder in 19, 4, and 3 patients, respectively. At p...

introduction here we report an unusual case of massive stone formation in augmented urinary bladder. case presentation a 25-year-old man presented with recurrent urinary tract infection ten years after augmentation cystoplasty after a complex pelvic fracture urethral distraction defect. on evaluation by ultrasonography, x-ray, and computed tomography of abdomen showed large burden of stones in ...

Infectious urolithiasis is a result of recurrent and chronic urinary tract infections caused by urease-positive bacteria, especially Proteus mirabilis. The main role in the development of this kind of stones is played by bacterial factors such as urease and extracellular polysaccharides, but urinary tract environment also contributes to this process. We used an in vitro model to establish how t...

Aim: Urinary reflux is a probable reason of nephrolithiasis among children. This study aimed to assess the relationship between urinary reflux and other reason of stone formation in children.Methods: This cross-sectional study was carried out with 199 children diagnosed with nephrolithiasis using ultrasonography. They were hospitalized in a referral children hospital in an urban area of in Iran...

BACKGROUND Urinary tract stones are increasing in our societies. Similar to the finding in developed countries, majority of our patients have upper urinary tract stones. Urethral stone is an uncommon cause of acute urinary retention. It presents with an emergency management scenario which is compounded by lack of endoscopic facilities in our hospitals. We present the management of urethral ston...

The prevalence of urinary stone disease in 426 patients who had undergone bowel surgery at the General Infirmary at Leeds from 1958 to 1978 was found by postal questionnaire to be 9.4%. The risk of urinary stone formation was determined from the composition of 24 hour urines from 61 unselected patients, in whom intestinal resections had been performed. There were 27 patients with an ileostomy, ...

Objective: To determine the chemical composition of spontaneously passed urinary stones. Study design: Descriptive. Place and duration: The study was conducted at public and private Pathology laboratories of Larkana from Jan: 2009 to Dec: 2010. Patients and methods: Stones of 278 patients were analyzed chemically, using titrimetric method for estimation of calcium and colorimetric method for ur...

INTRODUCTION The current report detailed an investigation of melamine-linked urinary stones in children exposed to contaminated formula. MATERIAL AND METHODS A total of 1062 children fed with melamine-contaminated infant formula were screened for urinary stones. Sixty healthy children without melamine exposure were recruited as a control group. Ultrasonography of the urinary tract system was ...

Introduction Mineralization inhibitors are required to prevent the precipitation of minerals and inhibit the formation of kidney stones and other ectopic calcifications. In laboratory studies, Fetuin-A as a glycoprotein has inhibited hydroxyapatite precipitation in calcium and phosphate supersaturated solutions; however, information about patients with kidney stones is limited. The aim of this ...

After urinary diversion patients are at increased risk of long-term complications, including stones of the upper urinary tract and reservoir or conduit. Advances in instrumentation and techniques have expanded treatment options, while minimizing morbidity. Minimally invasive treatment methods include shockwave lithotripsy, antegrade and retrograde ureteroscopic lithotripsy and percutaneous neph...
