Filter by:Calcium oxalate stone, the most common type worldwide, has a recurrence rate of around 50% in ten years. Therefore, identifying the underlying pathophysiological aspects via metabolic evaluation and suggestions for medical & dietary prophylaxis in calcium stone patients is of upmost importance. However, one of the greatest problem with metabolic evaluation and subsequent therapeutic advices is the patient compliance. Therefore, it is important to identify factors related to patient compliance for metabolic evaluation and medical & dietary prophylaxis in calcium stone patients
Sepsis is a lethal complication of flexible ureteroscopy. The aim of this study is to identify predictors of sepsis after flexible ureteroscopy in patients with solitary proximal ureteral stones.
Regarding to the distribution of nephrostomy tube (NT) size usage by country. There was a clear distinction between countries that used solely the small bore (SB) NT (Chile and Australia) and those that used solely the large bore (LB) NT (Czech Republic and Japan). There is also a trend toward SB NT in North America (~75% in USA and Canada) and toward LB NT in South America (~80% in Argentina and Mexico). In Europe the trend is equal (~50% in Germany, France, Greece and UK). Based on previous data and in view of conflicting data about postoperative complication including extravasation, bleeding and hemoglobin change and pain between previous studies, we will conduct this randomised trial comparing SB and LB NT following PNL. Our aim to evaluate the safety of small versus large bore NT reporting complications using the Clavien-Dindo system with categorisation of PNL-specific complications
The EUA Urolithiasis Guidelines Panel meta-analysis suggest that mPNL is at least as efficacious and safe as sPNL for the removal of renal calculi. However, the quality of the evidence was poor, drawn mainly from small studies, the majority of which were single-arm case series, and only one of which was RCT. The risks of bias and confounding were high, highlighting the need for more reliable data from RCTs. So, the Panel recommended for more clinical research . The aim of this study is to compare between PNL and mPNL through a randomized controlled trial.
This is a prospective randomized double-blind controlled trial assessing the benefits of intramuscular ketorolac before or immediately after office ureteral stent removal.
The ability to predict stone composition, which influences patient treatment, depends on the accurate measurement of CT attenuation of stones. We will study the effects of stone composition, stone size, and scan collimation width on the measurement of attenuation in vitro.
Patients suffering from acute renal colic are evaluated by non contrast computerized tomography with excellent identification rates of urinary stones. The scan also covers the bones of the ribs, spine and pelvis, allowing measurements of the bone density and identifying early osteopenic changes. Bone demineralization is associated with metabolic changes such as hypercalcemia or hypercalcuria. In this study the investigators will look for correlation between kidney stones, osteopenic bone changes and metabolic abnormalities.
The purpose of this study is to assess whether certain beverages can increase urinary citrate levels in healthy individuals with no history of kidney disease.
