A relation between vitamin D and citrate metabolism has been clearly established by various investigators, the first of whom was Dickens (l), followed by Nicolaysen and Nordbo (2), Harrison and Harrison (3), Freeman and Chang (4), Waasjo and &g-Larsen (5)) and Carlsson and Hollunger (6). In this laboratory, interest in citrate metabolism was aroused by the finding of citrate lithiasis in rats o...

The aetiological role of biliary lithiasis for chronic pancreatitis remains controversial. Previous studies based on pancreatographic studies reported changes in the pancreatic duct system caused by biliary lithiasis. This study analysed retrospectively the endoscopic retrograde cholangiopancreatography of 165 patients presenting with biliary lithiasis and of 53 controls. Among the 165 patients...

BACKGROUND The aim of the study was to determine the potential of magnetic resonance urography (MRU) in evaluation of paediatric urinary tract pathologies. PATIENTS AND METHODS.: Twenty-one paediatric urological patients were evaluated with T1, T2 prior and after and 3D gradient echo sequences after the contrast administration. Results were compared with findings obtained with ultrasound which...

OBJECTIVE To present our centre's experience in the surgical treatment of lithiasis in patients with horseshoe kidney. MATERIAL AND METHODS From October 2007 to March 2011 we treated 10 patients with renal lithiasis in their horseshoe kidneys. Retrospectively, we reviewed the symptoms, medical and surgical history, the characteristics of the stones (size, location, composition) and treatments...

The ethanolic extract of roots of Saccharum spontaneum Linn. was evaluated for its antilithiatic activity in rats. Lithiasis was induced by oral administration of ethylene glycolated water (0.75%) in adult male wistar albino rats for 28 days. The ionic chemistry of urine was altered by ethylene glycol (EG), which elevated the urinary concentration of crucial ions, viz. calcium, phosphorus and p...

Background: A very strict control of urinary pH is recommended to maintain it between 5.5 and 6.2, preventing formation or recurrence crystals. Kidney stones are a common problem, with high rate recurrence, not altered by the success surgery. Medical treatment prevents recurrence. Potassium Citrate inhibits crystallization calcium salts. It influences calculogenesis increasing citrates alkalini...

Medullary sponge kidney (renal spongiosis), (MSK) is a rare developmental anomaly of the unknown cause. It presumed, that people with genetic predisposition (<5% family occurrence) are prone to disease. The peak diagnosis between ages 20-50, usually by chance (due lack symptoms) during an abdominal X-ray, where so-called nephrocalcinosis (calcifications in kidney) can be observed. Another ra...

Meckel's diverticulum is the commonest congenital malformation of gastrointestinal tract and represents a persistent remnant of the omphalomesenteric duct. Although it mostly remains silent, it can present as bleeding, perforation, intestinal obstruction, intussusception, and tumours. These complications, especially bleeding, tend to be more common in the paediatric group and intestinal obstruc...
