“…Pseudoaneurysms on the other hand, remain the same size in the venous phase but show decreased attenuation. Arteriovenous fistulas are visualized as early contrast material filling into the renal vein in arterial phase images [14]. Additionally, CT images provide additional advantages such as providing information about the entry tract of the PNL procedures, identifying the patient's renal artery anatomy, and determining the level of vascular injury (segmental artery, interlobar artery, arcuate artery, etc.).…”

Objectives: The study aimed to evaluate the effectiveness and reliability of transarterial embolization (TAE) in managing delayed bleeding after percutaneous nephrolithotomy (PNL). Materials and Methods: Patients presenting to our hospital’s emergency department with hematuria following PNL and treated with TAE were included in the retrospective analysis. Demographic, clinical, and radiological data were collected. Technical and clinical success rates of TAE were calculated. The impact of the embolization procedure on kidney function was determined using angiographic images, and pre- and post-procedure serum creatinine levels. Results: A total of 13 patients included in the study presented with intermittent visible hematuria. The average interval between hematuria onset and PNL was 11.92±7.27 days. No hemodynamic instability was observed in any patient. CT angiography identified vascular pathology in 11 patients (84.6%), who subsequently underwent renal angiography for TAE without conservative treatment. Pseudoaneurysms were found in 7 patients (63.6%), and both pseudoaneurysms and arteriovenous fistulae in 4 patients (36.4%). Technical success was achieved in all embolization procedures. Hematuria resolved in all patients during follow up with a clinical success rate of 100%. Renal parenchymal loss after embolization was <%10 in 8 patients (72.7%), %11-24 in 2 patients (18.2%), and %25-50 in 1 patient (7.7%). There was no significant difference in serum creatinine levels before (mean 1.09±0.53 mg/dl) and after (mean 1.06±0.71 mg/dl) TAE (p=0.5). No major procedure related complications were observed. Conclusions: TAE is an effective and safe method for the treatment of delayed bleeding following PNL. CT angiography facilitates diagnosis and treatment planning for patients with hematuria after discharge. Early TAE for patients with identified vascular pathology can increase technical and clinical success rates.

“…Já a artéria renal esquerda, possui um curso mais horizontal à medida que passa posterolateralmente à veia renal esquerda. 1 Sabe-se que o conhecimento das variações anatômicas dos vasos renais (VAVR) apresentam grandes implicações clínicas. 2 Em casos de transplante renal, faz-se de essencial importância a realização de avaliações pré-operatórias cuidadosas para a detecção de anomalias vasculares renais e ureterais.…”

Sabe-se que o conhecimento das variações anatômicas dos vasos renais representa importante aplicação clínica e cirúrgica. Objetivo: Analisar a presença de variações anatômicas na irrigação renal das peças cadavéricas disponíveis para estudo anatômico do Laboratório de Anatomia da Faculdade de Ciências Médicas de São José dos Campos, bem como classificar as variações encontradas. Resultados: Os resultados evidenciaram a presença de uma variação anatômica nas peças estudadas, na qual foi identificada a existência de duas artérias renais direitas. Conclusões: A partir da metodologia empregada, pode-se concluir que a artéria renal supranumerária direita encontrada neste estudo, trata-se de uma variação anatômica pois esta não é encontrada na maioria dos seres humanos, ademais, atribui-se à esta, a classificação de artéria renal hilar, em razão de direcionar-se ao hilo renal.
