Cantharis dissolves calculus in the ureter of a kitten: case repor

Urolithiasis is a disease thatcan occur alone or together, obstruct the urinary flow, and even progress to the animal's death. Objective:The present study is to report the dissolution of calculus in the ureter in a kitten. Methodology: a feline, SRD, male, started at 3 months old with the signs of vomiting, constipation,and hematuria, presenting leukocytosis and increased serum urea. Two abdominal ultrasounds were performed 30 days apart and the third at 3 months. Results:Inthe first ultrasound there was hydronephrosis in the right kidney and dilation of the ureter and microlithiasis in the urinary bladder. The animalhad already been treated with antibiotic therapy and did not improve. Given these characteristics, Cantharis Vesicatoria30cH was administered, there was no more hematuria and when the drug was discontinued, the symptom returned. After 30 days of startinghomeopathic treatment, we repeated the ultrasound which showed 2 kidney stones, and a urinary bladder with cystitis associated with sandy lithiasis. BerberisVulgaris30cH was then administered for 15 days, after which both drugs were discontinued and theanimal remained asymptomatic. After 3 months the ultrasound was repeated which showed 2 kidney stones, Causticum6cH was inserted for 14 days to dissolvekidney stones, thus preventing the return of the initial symptoms. Conclusion:the treatment was beneficial for the patient, who was asymptomatic after the use of Causticum.Considering the natural history of the disease in cats and the high chance of recurrence of the disease, the recommendation was to monitor the organs through an annual ultrasound examination, in addition to encouraging water intake.

Beneficial antioxidative effect of the homeopathic preparation of Berberis vulgaris in alleviating oxidative stress in experimental urolithiasis.

BACKGROUND: Oxidative stress is a major mediator in the pathophysiology of several kidney diseases. The cellular damage is mediated by an alteration in the antioxidant status, which increases the concentration of reactive oxygen species (ROS) in the stationary state (oxidative stress). Therefore, interventions favoring the scavenging and/or depuration of ROS should attenuate or prevent the oxidative stress, thereby safeguarding the kidneys against damage. In this sense, this study attempts to evaluate the extent of oxidative stress in experimental urolithiasis by measuring some parameters of oxidant stress and antioxidant defenses in rat kidneys, before and after Berberis vulgaris homeopathic preparation supplementation, and to assess the role, if any, of homeopathic treatment in mitigating free radical toxicity in kidney stone disease. METHODS: Rat model of urolithiasis was established by administering 0.75% ethylene glycol (EG) in drinking water, and the effects of a homeopathic preparation of B. vulgaris root bark (HPBV) on the renal antioxidative defense system as well as on potent markers of free radical activities were investigated. RESULTS: HPBV brought about an augmentation in the activities of enzymatic antioxidants such as superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and glucose-6-phosphate dehydrogenase and improved the nonenzymatic antioxidants, e.g., tocopherol, ascorbic acid, and glutathione. HPBV ameliorated the malondialdehyde and protein carbonyl levels and restored renal thiols almost completely. CONCLUSION: Thus, it is shown that HPBV acts as a renoprotective remedy in alleviating the renal calculi-associated oxidative damage by upregulating the antioxidant status.

Evaluación del efecto antiurolitiásico e influencia en la función renal del extracto seco hidroalcohólico al 70% de Mikania cordifolia (L. f.) Willdenow en litiasis renal inducida en animales de experimentación / Evaluation of the anti-urolithic effect and influence on renal function of 70% hydroalcoholic dry extract of Mikania cordifolia (L. f.) Willdenow in induced kidney stones in experimental animals

La presente investigación tuvo como objetivo evaluar el efecto de tipo antiurolitiásico y la influencia en la función renal del extracto seco hidroalcohólico al 70% de Mikania cordifolia. (L.f.) Wildenow administrado por vía oral en ratas Holtzman previa inducción de litiasis renal por el método de hiperoxaluria (inducida con solución de etilenglicol al 0.75% y cloruro de amonio al 0.5% durante 21 días). Se planteó un estudio cuasi experimental con postprueba únicamente y grupos intactos. Se utilizaron 42 ratas albinas hembras las cuales fueron distribuidas en 6 grupos (n=7): de los cuales un grupo se tomó como testigo negativo y a los otros 5 se les indujo la litiasis renal. Una vez inducida la litiasis se tomó un grupo como testigo positivo y a los otros 4 se les administraron tratamiento con el extracto de la planta en estudio, a las dosis de 300 y 500 mg/ kg de peso, ambas durante 14 días y 21 días. Concluido el tiempo de tratamiento, se obtuvieron las muestras de sangre, orina y tejido renal. Se midieron los siguientes indicadores: flujo urinario, creatinina en suero y orina, sodio y potasio en suero y orina, pH en orina, acido oxálico en orina y se realizó el estudio histológico del tejido renal. El análisis de resultados indicó que el tratamiento con el extracto de la planta en estudio a las dosis de 300 mg/Kg durante 21 días y 500 mg/Kg durante 14 y 21 días, incrementan el flujo urinario en un 75%, 77.78% y 66.69% respectivamente; y la depuración de creatinina en un 50.93%, 52.03% y 54.16% respectivamente, de forma significativa respecto al grupo testigo positivo; así mismo disminuye Jos niveles de ácido oxálico en orina en un 48%, 80% y 66.1 %(a las dosis de 300 mg/Kg durante 21 días y 500 mg/Kg durante 14 y 21 días respectivamente) de forma significativa respecto al grupo testigo positivo. Los resultados del análisis histopatológico indican que a las dosis de 300 mg/Kg durante 21 días y 500 mg/Kg durante 14 días, la presencia de microcristales es escasa, mientras que a la dosis de 500 mg/Kg de peso durante 21 no se evidencia presencia de microcristales en el tejido renal. Se concluye que el extracto seco hidroalcohólico preparado de los tallos y hojas de Mikania cordifolia. (L.f.) Willdenow. Presenta efecto antiurolitiasico y mejora la función renal a la dosis de 500 mg/kg de peso desde los 14 días de tratamiento y a la dosis de 300 mg/kg a los 21 días de tratamiento.
