Right renal vein elongation with the inferior vena cava for cadaveric kidney transplants: an old neglected surgical approach

INTRODUCTION: Short right renal vein is a frequent and well-known technical inconvenience that is commonly observed during transplantation of the right kidney. We present our experience with the elongation of short cadaveric right renal veins using the contiguous vena cava during cadaveric renal transplants. METHODS: We performed 34 kidney transplantations with a short right renal vein requiring elongation using the inferior vena cava, to make the venous anastomosis technically feasible. The elongated right renal vein was anastomosed end to side to the external iliac vein in 24 patients, to the common iliac vein in 8 patients and to the inferior vena cava in 2 patients. The right renal artery with an aortic patch was implanted end to side in 33 patients, and end to end without aortic patch to the internal iliac artery in one patient. RESULTS: In all cases, the vascular anastomoses were easily performed in the recipient and no thrombosis was observed. CONCLUSION: Elongation of a short right renal vein with the inferior vena cava is a feasible mean to overcome technical problems that may compromise the results of cadaveric renal transplantation.

Evidenciaçäo precoce do halo de inibiçäo em antibiograma de rotina / Premature reading of the inhibition zones in antibiotic susceptibility testing

Os testes de sensibilidade aos antibióticos na rotina laboratorial oferecem resultados em 18-24 horas após o isolamento do microrganismo. Procurou-se um artifício de técnica, objetivando uma leitura precoce no método do disco. Várias leituras de medicaçäo do halo foram feitas em funçäo do tempo de incubaçäo das placas, utilizando-se o meio de cultura sem e com cloreto de 2,3 5-trifenilterazólio (TTC) em diversas concentraçöes . Os halos medidos em tempo precoce näo foram diferentes dos de 24 horas e a viragem do indicador para vermelho deu maior nitidez aos halos, numa concentraçäo de 0,01%. A técnica apresenta a vantagen de precocidade dos resultados, principalmente em se tratando de amostras bacterianas hospitalares
