Filter by:Research Problem: Shock wave lithotripsy (SWL) dramatically changed the management of renal and ureteral calculus disease. In vitro studies suggest that progressive increase in lithotripter energy output voltage could produce the best overall stone comminution in comparison with constant or deescalating energy output. However, it is possible that the beneficial impact of slow rate SWL on comminution of stones and stone free rates has masked any marginal benefits for energy output escalation. The Escalating SW method adds the benefit of less renal tissue injury. Research Significance:The present study will signifies and evaluates the stone free rates of three groups of patients with renal stones treated with different SWL energy outputs (Escalating, Constant and Reduction energy output). Research Objectives: The aim of this research project is to study the effect of dose adjustment strategies on success rate of Shock Wave Lithotripsy in the clinical setting and to optimize the conditions for successful Shock Wave Lithotripsy. Research Methodology: This clinical trial will be conducted at a tertiary care university hospital. 150 patients referred to the Shock wave lithotripsy unit will be evaluated for eligibility to be randomized into three groups (Dose Escalation, Dose reduction and constant dose). Parameter of the three groups will be compared to detect the treatment difference.
A prospective, single-center, single-arm, trial to demonstrate safety and device performance of the ADVA-Tec Uriprene™ Degradable Temporary Ureteral Stent. This is a first-in-man clinical study in a small human population.
This study tests moving kidney stones using focused ultrasound (referred to as ultrasonic propulsion). The study includes multiple population groups to investigate the ability of our technology to: a) move stone fragments to a location within the kidney to improve their chances of passage, and thus reduce the occurrence of additional symptomatic events and retreatment or b) move a symptomatic stone to relieve symptoms and pain.
This study is being done to obtain samples from patients with primary hyperoxaluria, cystinuria, adenine phosphoribosyl transferase (APRT) deficiency, and Dent disease, and from their family members, for use in future research.
The purpose of this study is to evaluate Efficacy and Safety of oral intake of Naftopidil 75mg once daily for the improving clearance of ureteral or renal stones.
The aim of this study is to identify the root cause for the significant discolouration of Boston Scientific Percuflex based stents.
The SKSC is a continuous database with the objective of a standardized diagnosis and monitoring of patients with kidney stones as well as the establishment of a Biobank.
The purpose of this study is to compare the role of potassium citrate supplementation with dietary education versus dietary education alone in the reduction of stone risks and events in patients with predominantly calcium phosphate kidney stones.
The purpose of this investigation is to prospectively evaluate the benefit of different methods of educating patients regarding their fluid intake through a readily available daily cellular phone application to improve overall urine output and reduce risk factors for stone recurrence.
This study will be conducted to compare the results of Laser and ultrasonic lithotripsy in disintegration of staghorn stones during percutaneous nephrolithotomy.
