Profile of renal artery embolization (RAE) for renal trauma: A comparison of data from two major trauma center

ABSTRACT Objective To evaluate usage of renal artery embolization (RAE) for renal injuries and discuss the indications for this treatment. Materials and Methods A retrospective study was performed evaluating the electronic medical records of all patients with renal trauma admitted to two major comprehensive hospitals in Shantou city from January 2006 to December 2015. Results There were 264 and 304 renal traumatic patients admitted to hospital A and B, respectively. LGRT was the reason for presentation in the majority of patients (522, 91.9%). A total of 534 (94.0%) patients were treated conservatively. RAE was performed in 9 patients from 2012 to 2015 at hospital A, including in 6 patients (6/9, 66.7%) with LGRT, and 3 patients (3/9, 33.3%) with HGRT. No patient underwent interventional therapy (RAE) at hospital B during the same period. No significant differences in the operative rate of hospital A were observed between the two time periods (2006-2011 and 2012-2015). The operative rate for LGRT between the two hospitals from 2006 to 2011 and 2012 to 2015 was not significantly different. Hospital A showed a significant decrease in the rate of conservative treatment for patients with LGRT. In the univariate and multivariate analyses, the AAST renal grade both were significantly associated with undergoing RAE. Conclusions LGRT was present in the majority of patients, and most cases of renal trauma could be treated with conservative treatment. RAE was well utilized for the treatment of renal trauma. However, some patients with LGRT were treated with unnecessary interventional therapy.

A novel endoscopic treatment for renal arteriopelvic fistula post-percutaneous nephrolithotomy (PCNL)

Main findings We describe the use of a novel endoscopic approach in the management of unremitting gross hematuria following post-percutaneous nephrolithotomy (PCNL) in a 65-years-old male. This approach proved successful and cost-effective in managing haemorrhage post-PCNL when renal angiography failed to localize the source of bleeding. Case hypothesis The recommended treatment modality for renal calculi ≥ 2cm is PCNL. It is essential that clinicians are aware of the various complications that can arise from PCNL, including arteriovenous fistula, which is typically managed with renal angio-embolization. The development of a renal arteriopelvic fistula (APF) is an extremely rare complication, and accounts of haemorrhage from renal APF and its treatment have not been well-described in the literature. We successfully hypothesized that the ureteroscopic localization, fulguration, and closure with a fibrin sealant at the site of the arterial bleed results in optimal treatment for this clinical presentation. We report this case in detail. Promising Future Implications The successful and cost-effective endoscopic approach described here for treatment of post-PCNL renal APF and unremitting gross hematuria ought to be considered as an adjunct to renal angiography and embolization when the source of bleeding cannot be accurately identified using traditional imaging modalities. .

Resultados e evolução intra-hospitalar da angioplastia de artéria renal na hipertensão renovascular / Renal vascular hypertension and renal artery angioplasty outcome and in hospital evolution

Fundamentos: Não está definido: usar stent em todas as etiologias de hipertensão renovascular e variáveis independentes para sucesso técnico e clínico. Objetivos: Avaliar resultados e evolução intra-hospitalar da intervenção percutânea de artéria renal, determinando variáveis independentes para sucesso técnico e resposta favorável da hipertensão arterial. Métodos: Foram analisados 88 procedimentos subdivididos em: Grupo A (n=25) ocorridos entre 1981 e 1992, quando o stent não estava disponível; e Grupo N (n=63) de 1993 a 2006, utilizando-se balão e/ou stent. Os procedimentos também foram agrupados de acordo com as duas principais etiologias: aterosclerose (n=68) e displasia fibromuscular (n=11). Resultados: Foram maiores no grupos N: idade, localização ostial e sucesso técnico 98,4 por cento versus 84,0 por cento (p=0,0216), com evolução hospitalar similar e favorável e pressão arterial sistólica pré e pós-procedimento similares nos dois grupos, sendo a pressão arterial diastólica pré e pós-procedimento menor no Grupo N...
