ABSTRACT
Os esteroides anabolizantes têm sido usados como arma terapêutica em diversas condições clínicas. Entretanto, o uso abusivo e indiscriminado, associado a outros suplementos nutricionais, tem gerado efeitos adversos graves. Relato do caso: Sexo masculino, 21 anos, admitido com náuseas, astenia, hiporexia, cefaleia e hipertensão arterial. Exames no sangue evidenciaram Cr: 3,9 mg/dl U:100 mg/dl e Cálcio total 14 mg/dl. Ultrassonografia e biópsia renal compatíveis com nefrocalcinose. Houve melhora gradativa da função renal e da calcemia após hidratação vigorosa e furosemida. Entretanto, após 1 ano, persistiram depósitos renais de cálcio e relação córticomedular reduzida ao ultrassom e creatinina estável em 1,4 mg/dl. Casos anteriores evidenciaram necrose tubular aguda e nefrite intersticial com poucos depósitos de cálcio no interstício renal. Nesse caso, encontramos nefrocalcinose acentuada associada à nefroesclerose. O objetivo deste estudo é relatar a ocorrência de injúria renal aguda com nefrocalcinose associada ao uso de esteroide anabolizante e oferecer uma revisão do assunto. .
The anabolic steroid have been used as a therapeutic tool in various clinical conditions. However, indiscriminate use associated with other nutritional supplements has generated serious adverse effects. Case report: Male, 21 years old, admitted with nausea, fatigue, appetite loss, headache and hypertension. Blood tests showed Cr: 3.9 mg% U: 100 mg% and Total Calcium 14 mg/dl. Ultrasonography and renal biopsy were consistent with nephrocalcinosis. There has been gradual improvement in renal function and calcium levels after vigorous hydration and furosemide. However, after 1 year, renal calcium deposits persist, corticomedullary ratio reduced in ultrasound and stable creatinine of 1.4 mg/dl. Previous cases showed acute tubular necrosis and interstitial nephritis with little calcium deposits in the renal interstitium. In this case we found severe nephrocalcinosis associated with nephrosclerosis. Our objective is to report the occurrence of acute kidney Injury with nephrocalcinosis associated with use of anabolic steroid and provide a review of the matter. .

Purpose Many medicinal plants have been employed during ages to treat urinary stones though the rationale behind their use is not well established. Thus, the present study was proposed to evaluate the effect of coconut water as a prophylactic agent in experimentally induced nephrolithiasis in a rat model. Materials and Methods The male Wistar rats were divided randomly into three groups. Animals of group I (control) were fed standard rat diet. In group II, the animals were administrated 0.75% ethylene glycol in drinking water for the induction of nephrolithiasis. Group III animals were administrated coconut water in addition to ethylene glycol. All the treatments were continued for a total duration of seven weeks. Results and Conclusion Treatment with coconut water inhibited crystal deposition in renal tissue as well as reduced the number of crystals in urine. Furthermore, coconut water also protected against impaired renal function and development of oxidative stress in the kidneys. The results indicate that coconut water could be a potential candidate for phytotherapy against urolithiasis. .
