Active clinical trials for "Lithiasis"

Acute lithiasis cholecystitis (ALC) is the third most common cause of surgical emergency admission. The initial treatment of ALC associates a medical support and a cholecystectomy, preferentially performed laparoscopically in the first 5 days of evolution. During the surgery, intraoperative cholangiography (CPO) using a contrast product is the "gold standard" to identify the bile ducts. However CPO is performed in approximately 30% of laparoscopic cholecystectomy. Laparoscopic cholecystectomy for ALC is associated with an increase in the rate of biliary ducts injuries compared with cholecystectomy for symptomatic vesicular lithiasis, evaluated at 0.8 % versus 0.1 %. Its higher rate is related to local inflammation that alters the biliary anatomy and complicates the identification of the bile ducts. Indocyanine green facilitates the visualization of extrahepatic biliary structures, which could reduce the risk of biliary wound and shorten the operating time.

This study is designed to compare analgesic effect of both the ultrasound (US)-guided QLB and ESPB blocks during ESWL and their effect on stone fragmentation.

The study will be prospective non-interventional and will include patients with kidney stones who are to undergo one of the following three techniques: retrograde nephrolithotripsy, percutaneous nephrolithotripsy and extracorporeal nephrolithotripsy depending on the size of the stone. Data regarding post operative descriptions will be recorded and comprehensive complication index will be used for the assesment of the burden.

The incidence of stone disease of the urinary tract in children is increasingly increasing with a remarkable economic impact for its management. This incidence is variable according to race, geographic region, socio-economic status and dietary habits. Oxalo-calcium stones are the most common but the biochemical nature of urinary stones varies depending on the region where those of a phosphatic nature are characterized by a higher incidence in Europe. The diagnosis is confirmed by imaging. The unprepared abdomen (ASP) has low diagnostic accuracy. The scanner is the reference tool but remains an irradiating examination. Risk factors for disease recurrence include primarily the presence of an underlying urinary metabolic abnormality and young age. Urinary metabolic abnormalities vary from one study to another. The understanding of lithogenesis, its evaluation as well as the therapeutic options is essential for adequate and adapted management in the pediatric population.

The purpose of this study is to determine whether Renalof administration promotes partial or total dissolution of urinary calculi and improves physicochemical parameters and metabolic activity in patients with recurrent calcic urolithiasis. The duration of this double-blind placebo controlled phase 3 clinical trial will be 12 weeks. The estimated number of patients to be recruited and randomized for the study is 110. Ultrasonographic and humoral parameters will be assessed every 4 weeks.

The extracorporeal shock wave lithotripsy (ESWL) is the treatment of choice for most stones in any of their locations. It is about breaking the stone without surgically intervening on the patient and getting him to expel the fragments himself. It is thought that additional treatments to the ESWL could improve the success rate of ESWL for less favorable stones. The components of our authorized food supplement have shown an inhibitory effect in vitro on the growth of calcium oxalate monohydrate crystals, even in hightly supersaturared solutions. Also these components show an inhibitory effect on the growth of calcium phosphate crystals. To sum up, it reduces the formation, inhibits the growth and promotes the dissolution of calcium oxalate and calcium phosphate kidney stones. This is the reason why this experimental study aims to modify the size limit of the stones in the ESWL with adjuvant food supplement.

Double blinded randomized controlled clinical trial to assess the impact of intraoperative Toradol on post-operative pain scores for patients undergoing ureteroscopy for urinary stone management.

To evaluate and compare the results of conventional and stepwise shock wave lithotripsy treatment modalities in pediatric urinary lithiasis.

Kidney stone disease affects almost 10% of overall population, often requiring a surgical intervention. Currently, shock wave lithotripsy is considered a first-line treatment option for patients suffering from symptomatic kidney stones smaller than 2.0 cm, providing reasonable stone-free rate. Actually, the outcomes from SWL vary largely due to several factors including stone burden, stone density, stone-skin distance (SSD), and patient's body habitus. Furthermore, the imaging exam modality (i.e. ultrasound versus computed tomography scan) performed to assess the presence of residual fragments also impacts on SWL outcome analysis. We aim to perform a well-controlled prospective evaluation of all variables that may impact on fragmentation and clearance of lower pole calculi after SWL. These variables are assessed exclusively by a noncontrast computed tomography scan (NCCT), eliminating the necessity of an intravenous urography to study renal collecting system anatomy; an imaging exam that is not routinely performed anymore for kidney stone patients.

In this pilot study, we wish to evaluate the performance of a robotic flexible ureteorscopy (ILY) in the treatment of nephrolithiasis in the superior excretory system
