Uric Acid Stones

Background: Kidney stones are one of the oldest known and common diseases in the urinary tract with a prevalence that varies from 1% to 20%. Many phytotherapic and herbal medicines for kidney stones have been described for their treatment and prevention. Objective: The objective of this study is to perform a comprehensive review of several phytotherapic and herbal medicines published including clinical and animal studies. Results: Phytotherapy may influence the risk of recurrence in calcium oxalate and uric acid stones. The most solid evidence suggest that Phyllanthus niruri is one of the most studied components that appear to interfere with the calcium oxalate crystallization, reduced hyperoxaluria and hiperuricosuria and increased shock wave lithotripsy efficacy due to reduced crystallization without significant adverse effects, also Theobromine have shown to reduce the crystallization of uric acid in patients and appears to be a promising supplement to treat such stones. Conclusion: Many phytoterapic and herbal agents have been studies to treat and present urolithiasis, most of them only with studies of small number of patients or in animal models. Further randomized clinical trials are needed to evaluate the effect of these agents in kidney stones.

Low Carbohydrate

Very-low-carbohydrate diets or ketogenic diets are frequently used for weight loss in adults and as a therapy for epilepsy in children. The incidence and characteristics of kidney stones in patients on ketogenic diets are not well studied. Methods: A systematic literature search was performed, using MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews from the databases’ inception through April 2020. Observational studies or clinical trials that provide data on the incidence and/or types of kidney stones in patients on ketogenic diets were included. We applied a random-effects model to estimate the incidence of kidney stones. Results: A total of 36 studies with 2795 patients on ketogenic diets were enrolled. The estimated pooled incidence of kidney stones was 5.9% (95% CI, 4.6–7.6%, I2 = 47%) in patients on ketogenic diets at a mean follow-up time of 3.7 +/− 2.9 years. Subgroup analyses demonstrated the estimated pooled incidence of kidney stones of 5.8% (95% CI, 4.4–7.5%, I2 = 49%) in children and 7.9% (95% CI, 2.8–20.1%, I2 = 29%) in adults, respectively. Within reported studies, 48.7% (95% CI, 33.2–64.6%) of kidney stones were uric stones, 36.5% (95% CI, 10.6–73.6%) were calcium-based (CaOx/CaP) stones, and 27.8% (95% CI, 12.1–51.9%) were mixed uric acid and calcium-based stones, respectively. Conclusions: The estimated incidence of kidney stones in patients on ketogenic diets is 5.9%. Its incidence is approximately 5.8% in children and 7.9% in adults. Uric acid stones are the most prevalent kidney stones in patients on ketogenic diets followed by calcium-based stones. These findings may impact the prevention and clinical management of kidney stones in patients on ketogenic diets.

Medicinal plants have bioactive compounds, which are used to treatments of various diseases. In the present study, Persicaria sagittata medicinal plant was used for the preliminary phytochemical screening. Methanol and petroleum ether were used as a solvent for obtaining the extraction of the plant. Both the extracts were further study for qualitative phytochemical screening using standard methods. Phytochemical screening shows that methanolic extract possesses the presence of tannins, flavonoids, and vitamin A as tannins and flavonoids are helpful for the uric acid stones. The study reveals that medicinal plant provides a basis of its use in medicine, improve to further drugs in the pharmaceutical area, and contains different biologically active constituents, and the secondary product is valuable of further analysis.

Background   Ethnicity play a role in the occurrence of urinary stones, probably related to climatic, environmental and dietary factors in ethnic groups. The association between ethnicity, age, clinical profile, stone size with type of ureteric stones among males with urolithiasis was studied.   Materials and Methods Male patients (>18 years) with lower ureteral stones size <10mm attending outpatient department of Urology, at a private hospital, Ajman over a period of one year were included. Ethics approval was obtained from Institutional Ethics Committee. Data was retrieved from the case records which included socio-demographic variables (age, ethnicity), clinical profile (ureteric colic, duration of pain, other complaints), and laboratory investigations (type of stone, stone size). Descriptive and inferential statistics were performed with SPSS-20 and p values <0.05 considered significant. Results 185 male patients were included. Mean age was 41.5 (7.3) years, range (22-71) years. Out of the total, 81 (43.8%) patients were Asians, 81(43.8%) Arabs and 23 (12.4%) were of other ethnicity. Most patients (95.1%) presented with ureteric pain. 49 (26.5%) had family history of stone disease where calcium oxalate monohydrate and uric acid stones were common, with majority being first degree relation. Data on stone type was available for 90 patients; of which, 21 were calcium oxalate monohydrate, 33-calcium oxalate dehydrate, 24-uric acid and remaining 12 other form of stones. Average age for different types of stone was 38.3, 41.6, 39.4 and 42.8 years for calcium oxalate monohydrate, calcium oxalate dehydrate, uric acid and other types respectively. Conclusion Uric acid stones were more prevalent among Asians and calcium oxalate-dehydrate stones among Arabs. Future studies can be conducted among multiethnic population focusing on dietary pattern and stone analysis.DOI: http://dx.doi.org/10.3126/nje.v4i4.11359 Nepal Journal of Epidemiology 2014; 4(4):393-98
