Filter by:The investigators will investigate the safety and effectiveness of an Iranian traditional medicine regarding its ability to dissolve existing kidney stones. Calcium stone formers will be recruited for a 12 week trial. Each subject will receive Lapis judaicus or placebo in random order. End points are changes in urinary chemistries and stone burden by Ultra sonography / CT scan. It will be used in proven calcium stone forming adults who are not pregnant. This phase is a double blind, randomized, placebo controlled Entry, first and 12 week 24 hour urine supersaturations, pH and sodium determinations will be collected. Entry and final stone quantification Ultra sonography / CT scan will be performed. End points will be changes in urine chemistry/supersaturation and stone quantitative stone volume.
Outpatient tubeless Percutaneous nephrolithotomy (PCNL) could potentially improve patient care and result in significant cost savings for our hospital each year. If this pilot study is successful, Queen's/KGH will lead a collaborative national multicentre trial to further establish the role of this new approach in the surgical treatment of kidney stones.
This study will sought to determine if limited urine collections can provide similar or more informative data than standard 24-hour urine collections used to evaluate kidney stone formers.
This is a randomized control trial (meaning the selection is random as when flipping a coin) to assess the benefit of paravertebral blockade (PVB) in Percutaneous nephrolithotomy/nephrolithotripsy (PCNL) surgery.
More specifically, the present invention relates to a 'Herbal Preparation' that is useful for - Treatment of Renal calculi - Reduction in the stone size & surface area - The expulsion of stone - Decreased need of Analgesic(Antiinflammatory Effect) - Stops the recurrence and reformation of renal
Beverages containing citrate may be useful in increasing urine citrate content and urine pH. Such changes in urine chemistry could help prevent kidney stones. Diet orange soda has more citrate than other similar beverages. The investigators are interested in whether diet soda will improve urine chemistry in the appropriate manner.
Extracorporeal shock wave lithotripsy (ESWL) and Percutaneous nephrolithotomy (PCNL) become the therapy of choice for renal stone. Although providing good results, stone recurrence is usually found as the therapies do not change the underlying metabolic abnormality. Among the metabolic disorders, hypocitraturia is an important risk factor for calcium nephrolithiasis. This study evaluate the preventive effects of potassium sodium citrate on stone recurrence as well as stone growth post ESWL or PCNL, in patients with calcium-containing stones.
Authors want to investigate the usefulness of flexible cystoscopy in performing laparoscopic pyelolithotomies and ureterolithotomies by comparing operative results of a single surgeon's experience.
The study aims to investigate the pharmacokinetic parameters and its antioxidative effects in Thai healthy men.
Shockwave lithotripsy (SWL) is a safe, non-invasive treatment for renal calculi. During SWL energy is focused on in order to break kidney stones and this energy can be varied in size from a narrow (or small) focal zone to a wide (or large) focal zone. This is a multi-centered, randomized study comparing the single treatment success rates of narrow and wide focal zones during SWL.
