Active clinical trials for "Kidney Calculi"

The purpose of this study is to determine whether Tramadol Hcl is as effective as Voltaren a non-steroidal antiinflammatory drug, and Dipyrone in amelioration of the pain caused by acute renal colic.

Several studies were conducted to compare extracorporeal shockwave lithotripsy (SWL) and percutaneous nephrolithotomy (PNL) as treatment options for medium size lower caliceal high dense stones. However, no studies compared these options for non- lower polar stones. In the present study the investigators will compare mini-PNL and SWL in treatment of non- lower polar, medium size, high dense renal stones in reference to the stone free rate and safety of the procedures. Pre-operative evaluation including abdominal non-contrasted computed tomography will be performed for all patients. Patients will be randomly allocated into two equal groups and will be treated by either mini-PNL or SWL. postoperative, patients will be followed by regularly for 3 months. the outcome of the procedures will be evaluated and compared between groups.

The purpose of this study is to measure how well two different devices work to break up and remove kidney stones. We are comparing a newer device to an older one to see which one is faster at breaking up kidney stones. We hypothesize that the Trilogy will increase the stone clearance rate by 25% compared to the Shockpulse-SE

Between June 1997-June 2018, 573 pediatric patients underwent PCNL for renal stone disease by senior surgeons. Data was disunited into 2 groups. The study showed that PCNL is an operator-dependent procedure, with the improvement of outcomes over time, presumably due to increased operator experience and the involvement of a team member with substantial prior experience During 20 years, by gaining experience and with the development of new tools and optics, fluoroscopy time, operation time, blood loss and complication rates decreased and stone-free rates increased.

Urolithiasis is a common health problem worldwide affecting approximately 10% of the population at some stage in their lives. The aim of this study is to evaluate the efficacy of adjuvant treatment with tamsulosin for improving the stone-free rate after a single session of extracorporeal shock wave lithotripsy (ESWL) in the treatment of radiopaque kidney stones.

Hydroxycitrate (HCA) is a compound extracted from the fruit, Garcinia Cambogia. Hydroxycitrate supplements are available over the counter and are primarily promoted as a weight loss supplement. There has been recent evidence that hydroxycitrate is a potent inhibitor of calcium oxalate crystal growth and can lead to the dissolution of the crystals. The purpose of this research study is to study the effect of Hydroxycitrate (HCA) supplements on HCA urinary excretion and on urine chemistries in kidney stone formers and normal subjects.

Epidemiological studies have shown a progressive increase in the incidence of pediatric urolithiasis over the past few decades.

Extracorporeal shock wave lithotripsy (ESWL) is the least invasive and effective treatment for upper ureteric stones with a stone clearance rate of 60-90%. Tamsulosin is an alpha-blocker widely used in urological practice to relax smooth muscle of the prostate and bladder neck. Its role as part of medical expulsion therapy for the treatment of patients with kidney and ureteric stones has proved to be of considerable success. However, its role in clearing upper ureteric stones as an adjunct to ESWL is controversial. Therefore, this study will be conducted to evaluate its role in stone clearance along with extracorporeal shock wave lithotripsy in patients with upper ureteric stones

Urolithiasis is a frequent pathology, for which flexible ureteroscopy with endocorporeal laser lithotripsy has become the most frequently used surgical treatment. This procedure is limited to 90 minutes and will depend mainly on the total lithiasis volume. Knowing the duration of lithotripsy before the operation would allow to foresee situations of iterative procedures and to improve the patient's path (ambulatory or conventional surgery, work stoppage, optimization of operating times and operating room occupation times). "Kidney Stone Calculator" is a free tool capable of providing a calculi volumetry and predicting the duration of endocorporeal laser lithotripsy. The main objective of this study would be to evaluate the performance of the Kidney Stone Calculator in estimating the duration of laser lithotripsy during flexible ureteroscopy for renal calculi, by analyzing the agreement between the estimated and actual lithotripsy durations, evaluated by an intraclass correlation coefficient and its 95% confidence interval Eligible patients will be those scheduled for flexible ureteroscopy for renal calculi described on a non-injected abdominopelvic scan. A total of 240 patients over a 15-month inclusion period is planned, with a follow-up time of 3 months.

The aim of this study is to prospectively analyze patient satisfaction, pain, delivered energy and clinical effectiveness of using VR as a complimentary treatment modality during SWL.
