Abstract Current theories of renal stone formation are reviewed, together with the resulting proposals for treatment, with emphasis on the idiopathic, recurrent formation of calcium oxalate stones. Factors influencing the initiation and development of stones are discussed.

1. Anomalous transmembrane anion transport has been observed in erythrocytes of patients with idiopathic calcium nephrolithiasis. 2. To verify whether cation transport is also abnormal, we investigated the frusemide-sensitive Na+ efflux from Na+-loaded erythrocytes and the natriuretic response to acute intravenous frusemide administration in calcium oxalate renal stone formers. 3. Frusemide administration induced a statistically significant smaller increase in the fractional excretion of Na+ in patients than in control subjects. Abnormal kinetic properties of erythrocyte Na+-K+-2Cl− co-transport were observed in approximately 60% of stone formers. The Km for Na+ of Na+-K+-2Cl− co-transport correlated with urinary Ca2+ excretion. 4. The abnormal kinetic properties of Na+-K+-2Cl− co-transport may be relevant for stone formation, hampering renal Ca2+ reabsorption in the distal nephron and determining critical physicochemical conditions for calcium/oxalate crystallization.

In the pathogenesis of hypercalciuria and hyperoxaluria, n-6 polyunsaturated fatty acids (PUFAs) have been implicated by virtue of their metabolic links with arachidonic acid (AA) and prostaglandin PGE2. Studies have also shown that n-3 PUFAs, particularly those in fish oil—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—can serve as competitive substrates for AA in the n-6 series and can be incorporated into cell membrane phospholipids in the latter’s place, thereby reducing urinary excretions of calcium and oxalate. The present review interrogates several different types of study which address the question of the potential roles played by dietary PUFAs in modulating stone formation. Included among these are human trials that have investigated the effects of dietary PUFA interventions. We identified 16 such trials. Besides fish oil (EPA+DHA), other supplements such as evening primrose oil containing n-6 FAs linoleic acid (LA) and γ-linolenic acid (GLA) were tested. Urinary excretion of calcium or oxalate or both decreased in most trials. However, these decreases were most prominent in the fish oil trials. We recommend the administration of fish oil containing EPA and DHA in the management of calcium oxalate urolithiasis.

Objective. The study aimed to determine if Blumea balsamifera inhibits calcium oxalate stone formation in the kidneys through determination of the number of calcium oxalate stones in the renal cortex and the percent mass of calcium oxalate. Methods. Post-test only control group design was used using five treatment groups with placebo as the negative control, potassium citrate as the positive control, and 50%, 100%, and 200% sambong treatment. Urolithiasis was induced through ethylene glycol and ammonium chloride. Each treatment group was administered its corresponding treatment solution once daily for twenty-one days. Histopathologic examination and kidney homogenate analysis were done to determine the degree of deposition of calcium oxalate stones in renal tissues and the oxalate content, respectively. Statistical analyses were performed using one-way ANOVA and post hoc Gabriel's Pairwise Comparisons Test. Results. The 100% sambong treatment group showed the least mean number of stones while the positive control and 50% sambong treatment group exhibited the highest anti-urolithiatic activity in terms of oxalate content of the kidney homogenate. Conclusion. It can be concluded from the study that Blumea balsamifera inhibits calcium oxalate stone formation in the kidneys with the 100% and 50% sambong treatment most effective in decreasing number of stones and oxalate content of the kidney homogenate, respectively.

Hasah al-Kulya (renal calculi) is one of the leading problems affecting kidney. Recurrence of kidney stone formation is approximately 50%, after 2-3 years of recovery. This makes the prevention of its recurrence an essential problem to address. Despite substantial progress in medical therapy, there is no drug with satisfactory effect. Furthermore, the drugs those are being used for its treatment have many side effects. Baranjasif (Achillea millefolium Linn.) is one of the drugs used in Unani Medicine that has been extensively used for the management of urolithiasis. The aim of this study is to evaluate the lithotriptic action of Baranjasif in-vitro. In this study, calcium oxalate stones were prepared experimentally followed by the preparation of semipermeable membrane by dissolving the outer shell of egg in 2M HCl overnight. Calcium oxalate stones weighing 10mg were then allowed to react with 7 extracts of A. millefolium L. viz, Pet-ether, Chloroform, Ethyl Acetate, Methanol, Acetone, Hydro-alcohol and Aqueous by packing them together in semipermeable membrane. The reaction was performed on three different concentrations of each extract i.e., 50 mg, 100 mg and 150 mg. In addition to 7 groups, two more groups were taken, i) a negative group containing only the stone of weight 10 mg and ii) standard group consisting of stone weighing 10 mg and cystone (in concentrations of 50 mg, 100 mg and 150 mg). Statistical methods like mean standard deviation, percentage dissolution, percentage inhibition, IC and Pearson's correlation were applied to understand the extent of dissolution of stones 50 in each group. The study advocates that Baranjasif reveals lithotriptic activity comparable to standard drug. The efficacy of the drug is directly proportional to its concentration. Ethyl acetate extract of the plant showed the most promising results.
