“…Traditionally, renal angiography and excretory urography have been used to evaluate the anatomy of renal arteries and renal function, respectively, in potential kidney donors. However, several studies have shown that helical computed tomography (CT) angiography can replace renal angiography and excretory urography in the evaluation of potential kidney donors (3)(4)(5)(6)(7)(8)(9). Hence, helical CT angiography has become an accepted method for the evaluation of living donors before they undergo laparoscopic nephrectomy.…”

Rapid Estimation of Split Renal Function in Kidney Donors using software developed for Computed Tomographic Renal Volumetry AbstractPurpose: To evaluate the speed and precision of split renal volume(SRV) measurement (SRV), which is the ratio of unilateral renal volume to bilateral renal volume, using a newly developed software for computed tomographic (CT) volumetry and to investigate the usefulness of SRV for the estimation of split renal function (SRF) in kidney donors.Method: Both dynamic CT and renal scintigraphy in 28 adult potential living renal donors were the subjects of this study. We calculated SRV using the newly developed volumetric software built into a PACS viewer (n-SRV), and compared it with SRV calculated using a conventional workstation, ZIOSOFT (z-SRV). The correlation with split renal function (SRF) using 99m Tc-DMSA scintigraphy was also investigated.Results: The time required for volumetry of bilateral kidneys with the newly developed software (16.7 ± 3.9sec) was significantly shorter than that of the workstation (102.6 ± 38.9 sec, p<0.0001). The results of n-SRV (49.7 ± 4.0%) were highly consistent with those of z-SRV (49.9 ± 3.6%), with a mean discrepancy of 0.12 ± 0.84%. The SRF also agreed well with the n-SRV, with a mean discrepancy of 0.25 ± 1.65%. The dominant side determined by SRF and n-SRV showed agreement in 26 of 28 cases (92.9%).Conclusion: The newly developed software for CT volumetry was more rapid than the conventional workstation volumetry and just as accurate, and was suggested to be useful for the estimation of SRF and thus the dominant side in kidney donors.

“…At our center, we decide on the side to be donated based on simplicity of vascular anatomy on CT angiography and results of a nuclear medicine renal function scan [3,11]. If decision on side is equivocal, the right side is usually preferred, given the easier mobilization and avoidance of the risk of splenic injury.…”

Is right laparoscopic donor nephrectomy right?

et al. 2008

View full text Add to dashboard Cite

Right laparoscopic donor nephrectomy requires less operating time than, and is associated with similar outcomes for donors and recipients as, left laparoscopic donor nephrectomy. Right laparoscopic donor nephrectomy may be preferable in general and should be considered when multiple renal vessels are present on the left side and/or when preoperative function of the left kidney is greater than the right.

RESUMEN TRASPLANTE RENAL DE DONANTE VIVO: EVALUACIÓN DE LOS CANDIDATOS MEDIANTE TC HELICOIDALIntroducción y objetivos: La tomografía computarizada (TC) ha ganado aceptación en los últimos años en la evaluación vascular de los candidatos a donante vivo de riñón (DVR). Presentamos los hallazgos observados en una serie consecutiva de 102 candidatos y la correlación hallada con los datos quirúrgicos en los individuos que fueron intervenidos.Métodos: Desde Mayo de1995 hasta Junio de 2005 fueron evaluados mediante TC 102 candidatos a DVR. En 18 de ellos se realizó también angiografía por sustracción digital (ASD). Cincuenta y ocho candidatos fueron finalmente nefrectomizados para la donación. Se han analizado la prevalencia de variantes arteriales y venosas en los estudios TC realizados, así como su correlación con los datos de la ASD y la cirugía.Resultados: El 44% de los candidatos presentaron arterias renales supernumerarias en al menos un riñón. El 71% de riñones derechos y el 76% de riñones izquierdos tenían pedículo único. La presencia de bifurcaciones precoces fue del 7,8% y del 15,7% en cada lado y la de variantes venosas en el 17,5% y en el 13,7% en cada lado respectivamente. La sensibilidad de la TC en relación a la ASD para detectar pedículo arterial múltiple fue del 89%, la especificidad del 100% y la precisión diagnóstica del 97%. La correlación observada entre la cirugía y la TC en cuanto a la presencia de variantes arteriales fue del 93%.Conclusiones: Las variantes de la normalidad en el pedículo vascular renal tienen elevada prevalencia. La TC helicoidal permite obtener toda la información morfológica necesaria para la cirugía con elevada efectividad y en una sola sesión en los candidatos a DVR.Palabras clave: Tomografía computerizada.

ABSTRACT LIVING DONOR KIDNEY TRANSPLANTATION: HELICAL CT EVALUATION OF CANDIDATESObjectives: Computed tomography (CT) is a diagnostic tool that has won acceptance in the past years for the vascular evaluation of living renal donor (LRD) candidates. We show the findings observed in a series of 102 candidates consecutively evaluated in our centre and present the correlation with the surgical data obtained in those individuals finally operated.Methods: From May 1995 to June 2005, 102 LRD candidates were evaluated with CT. Eighteen were also studied with digital subtraction angiography (DSA). Fifty-eight donors underwent nephrectomy. Prevalence of arterial and venous variants found on CT exams were analyzed, as well as the correlation with surgical and DSA data when they were obtained.Results: Forty-four percent candidates showed multiple renal arteries at least in one kidney. Seventy-one percent of right kidneys and 76% of left kidneys had a single arterial pedicle. Early branching was observed in 7.8% and 15.7% in right and left kidneys respectively. Venous variants were present in 17.5% and the 13.7% in right and left sides respectively. Sensitivity, specificity and accuracy of CT to detect accessory arteries were 89%, 100% and 97% respectively ...

Helical Computerized Tomography Arteriography for Evaluation of Live Renal Donors Undergoing Laparoscopic Nephrectomy

Abstract: Helical CT is highly accurate and specific for the demonstration of renal arterial anatomy. Poor opacification resulted in a lower sensitivity for venous anatomy. Overall, helical CT provides essential anatomical information, and is an alternative to standard urography and arteriography.
