“…Due to a high consumption of oxygen during cellular metabolism, the kidney is highly affected in the setting of vaso-occlusive crises, which are characteristic of SCD. The environment surrounding the renal medulla is characterized by acidosis, hypertonicity, and hypoxia, and these factors contribute to the sickle cell crisis that is responsible for the occlusion of the renal vessels 3 . The most important consequence of these crises is damage to the renal tubules; this causes atrophy or dilation of the tubules, the presence of protein cylinders, and iron deposition along with degeneration of the tubule epithelium 1, 7…”

“…Treatment for hematuria is conservative and includes bed rest, maintenance of a high urine flow rate, urine alkalinization, and (if necessary) blood transfusions 1 . Most episodes are limited but can occur due to micro infarctions in the renal pyramids, which may be associated with renal papillary necrosis 3, 7…”

“…O estágio final deste processo deletério são hemácias irreversivelmente falcizadas. 3,8,9 Algumas consequências da falcização incluem: (1) enrijecimento e distorção das hemácias, que conduzem a sua destruição (hemólise) prematura; (2) depleção de óxido nítrico; (3) maior ativação à coagulação sanguínea; (4) intensificação das lesões microvasculares. 2,3 Essas modificações têm repercussões que as amplificam, levando a manifestações clínicas como anemia profunda, eventos vaso-oclusivos agudos e comprometimento de múltiplos órgãos, como episódios cerebrovasculares, síndrome torácica aguda, retinopatia e nefropatia.…”

“…14,[20][21][22] A hipostenúria, inabilidade de concentrar a urina sob condições de privação de água, é a anormalidade renal clinicamente mais conhecida na DF e a primeira manifestação de envolvimento dos rins associada à falcização. 6,9 Menos comumente ocorre inabilidade de acidificação da urina, sendo o distúrbio caracterizado como uma acidose tubular renal distal incompleta com a ocorrência de hipercloremia e hiperpotassemia. 4 A hematúria também é uma das manifestações clínicas frequentes associadas à nefropatia falciforme.…”
