Laparoscopic cholecystectomy is a well-known procedure for the treatment of most gallbladder diseases. Sometimes, it could be very difficult, in the presence of aberrations regarding the cystic duct, the cystic artery, or the gallbladder itself. Fluorescence laparoscopy using indocyanine green could be very useful for all the situations of anatomy aberrations.

BACKGROUND: Various genetic and environmental factors are involved in urolithiasis. The 2 most common metabolic abnormalities are the increase in urinary calcium and low urinary citrate excretion. The ratio calculated between the concentrations of both substances is a good risk marker for the formation of calcium stones. OBJECTIVES: To determine whether the risk of urinary calcium stone formation changes throughout the day in the same patient. METHODS: We studied 56 children (23V, 33M) to check if they had prelithiasis...

Glucagon-like peptide 1 receptor agonists (GLP-1RA) are the newest treatment for diabetes mellitus (DM). These drugs can down-regulate fasting glucose more than oral drugs and lead to more constant glucose levels compared to regular insulin. Acute pancreatitis is a serious condition that may have a fatal outcome. It has been shown that long term and high doses of GLP-1RA can cause pancreatic changes in animals, but no connection has been proven in humans. We present the case of a 67 years old man with DM treated with oral drugs for 10 years until 3 months before, when GLP-1RA was added...

AIM: Biliary lithiasis is common in most western countries. Symptomatic patients will also have choledocholithiasis in 10% of the cases. For patients with intermediate probability of CBD stones, the recommended imaging studies are endoscopic ultrasound (EUS) or MRCP. This study aims to identify early factors that can be used as predictors for the presence of CBD stones, and by that to find which patient should undergo ERCP without an early EUS. METHODS: This is a retrospective cohort study including all patients who underwent EUS for suspected choledocholithiasis at the Soroka University Medical Center (SUMC) in the years 2009-2014...

BACKGROUND: Minimally invasive procedures have become the standard option for treatment of urinary stones; the use of more invasive techniques is not a common practice currently. This emergent technology is not always available and laparoscopy is the alternative option. There are few reports of laparoscopic management for urinary lithiasis in pediatric patients. This study is about the use of laparoscopic surgery combined with pyeloscopy as a feasible first-line treatment for pediatric urolithiasis in renal and proximal ureteral locations...

BACKGROUND: Uric acid (UA) stones are responsible for 5-10% of the formation of all kidney stones. Recently, an association between UA stones and insulin resistance, diabetes mellitus, and obesity has been demonstrated and so the incidence has increased. The development of UA stones is dependent on several risk factors, including genetic predisposition, geographical location, dietary indiscretion, and various metabolic characteristics. SUMMARY: UA nephrolithiasis can arise from diverse etiologies, all with distinct underlying defects converging to one or more of 3 defects of hyperuricosuria, acidic urine pH, and low urinary volume...

This review brings together concepts of uric acid metabolism affecting renal parenchyma and its function and the current therapies to reduce hyperuricemia (HyU) and avoid renal disease progression. High uric acid plays an important role in several chronic diseases including kidney diseases such as lithiasis, gout nephropathy, and preeclampsia. In the last 30 years, it has been shown that reducing HyU with low protein and low purine diets in addition to allopurinol creates physiopathological conditions that produce a slight increase in the glomerular filtration rate (GFR)...

Several studies show the importance of serum vitamin D sufficient levels to prevent multiple chronic diseases. However, vitamin D supplementation and its effects on urine calcium excretion remain controversial. The objective of this prospective and interventional study was to evaluate urine calcium excretion in women with normal calciuria or hypercalciuria, once serum vitamin D sufficiency was achieved. We studied 63 women with idiopathic hypercalciuria, (9 with renal lithiasis) and 50 normocalciuric women...

In recent years, the role of trace elements in lithogenesis has received steadily increasing attention. It is well documented that some trace elements can influence the morphology and speed of the crystallization process. Zinc has been found in significant amounts in calcium stones relative or organic stones (uric acid and cystine), probably substituting calcium in crystals because of their similarity in charge and size. High Zn levels are present in carbapatite of Randal's plaques suggesting that zinc could promote calcium phosphate deposition in the medullar interstitium...

Urinary tract diseases are among the main reasons for consultation in veterinary clinics and hospitals. It affects animals of any age, breed and gender. Among the diseases that affect this system, urolithiasis is the second largest cause of clinical signs compatible with feline urinary tract disease. The term urolithiasis refers to the presence of uroliths in any region of the urinary tract, but it is more commonly seen in the bladder and urethra. Uroliths are classified based on the type of mineral present in their composition, therefore, quantitative and qualitative analyzes are important for a better therapeutic approach...

INTRODUCTION: Urinary lithiasis is a recurrent disease defined by the presence of calculi in the urinary tract. Most urinary calculi have as a major component calcium oxalate which occurs mainly in two crystalline forms: Calcium oxalate monohydrate (whewellite) and calcium oxalate dihydrate (weddellite). The target behind, this work is to study the inhibiting effect of the calcium oxalate's crystallization by the extract of the Ammi visnaga and the Punica granatum. METHODS: The inhibition of crystallization has been studied in vitro with both the absence and the presence of the different concentrations of the extracts of the two plants...

Primary hyperoxaluria (PH) is a very rare genetic disorder; it is characterized by total or partial deficiency of the enzymes related to the metabolism of glyoxylate, with an overproduction of calcium oxalate that is deposited in different organs, mainly the kidney, leading to recurrent lithiasis, nephrocalcinosis and end stage renal disease (ESRD). In patients with ESRD that receive kidney transplantation alone, the disease has a relapse of 100%, with graft loss in a high percentage of patients in the first 5 years of transplantation...
