Abstract The present study was undertaken to determine the efficacy of 16 spiral CT angiography in premature evaluation of vascular anatomy of live kidney donors. This study was performed in 200 candidates for renal transplantation planning to do donor nephrectomy. These 200 randomly chosen donors collected from February 2007 up to April 2008 in the Central hospital of Tripoli in the renal transplantation centre, and screened by helical CT scanning angiography prior to renal transplantation. In the present study, MRA originated between upper margin of L1 and lower margin of L2 vertrbra. Multiple renal artery variations are reported as : 1. Polar arteries were found in 5-25% of the donors (21 kidneys). The polar artery that enter the upper pole were found in 2.75% (17 kidney) and the lower pole 2.5% (10 kidneys). 2. accessory arteries were found in 23.5 % (94 kidneys). The accessory renal artery that pass through the upper pole were found in 10% (40 kidneys), the lower pole found in 11. 25% (45 kidneys) and both poles in 2.5% (9 kidneys). 3. Extrahilar (early) branching renal arteries were found in 12.25% of donors (49 kidneys). The extrahilar arteries that enter the upper pole occurs in 6% (24 kidneys), the lower pole 3-5% (14 kidneys) and through the hilum in 2.75 % (17 kidneys). In conclusion, review of the 3D date set alone by using 16 – section CT scan provide focused renal vascular, pelvicalyceal system, and ureteral results nth high senility and specificity and good diagnostic confidence, thereby reducing the necessary interpretation lime. Spiral CT holds promise as a single examination of living renal donors. |
