Introduction: Traditionally live related renal donors are evaluated with intravenous urography and renal arteriography. The computerized tomographic angiography (CTA) can offer a less invasive alternative to demonstrate the necessary anatomical and functional information. The present study evaluates the accuracy of helical CTA in depicting renal vascular and parenchymal anatomy in live renal donors.
Patients and Methods: During March 1999 to March 2000 all live donors were evaluated with ultrasound abdomen (USG), intravenous urography (IVU) and helical CT (Picker PQ 5000, Picker Intl. USA). Renal arterial and venous anatomy was documented prospectively by a radiologist, which was correlated with the operative findings. Sensitivity, specificity and accuracy of CTA in depicting the renal vascular anatomy were assessed.
Results: Of 120 live donors evaluated, overall concordance between CT angiography and operative findings in delineating the arterial anatomy was found in 110 (91.6%) and venous in 116 (96.6%) donors. The sensitivity, specificity, and accuracy of CTA in depicting arterial anatomy was 91.6%, 98.2% & 91.6% and for venous anatomy was 96.7%, 90.0% and 97.0% respectively. We could not gather any additional information by performing intravenous urography.
Conclusions: Helical CT angiography, which is highly specific for arterial and venous anatomy as well as other anatomical and functional details, can become the single imaging modality for preoperative assessment of potential donors in place of conventional angiography and IVU. CTA, being minimally invasive and cost effective, is well accepted by a normal healthy donor |
