Living donor renal transplantation has become major treatment for patients with end-stage renal disease. Preoperative evaluation of potential renal donors is crucial for selecting proper donors and the surgical technique. Multi- detector computed tomographic (MDCT) angiography is a noninvasive technique for preoperative evaluation of potential renal donors. As the practice of renal transplant has recently been started in Afghanistan, therefore authors aimed to look for the variation of renal vasculature, collecting system and other congenital and acquired anomalies.
To evaluate the normal anatomy, congenital variants and acquired abnormalities of kidneys and renal vasculature in healthy afghan population (probable renal donor)
Cross sectional descriptive study has been conducted on probable renal donors who underwent abdominal MDCT at radiology department of French Medical Institute for Mothers and Children (FMIC) from May 2017 to Dec 2017. MDCT images were reviewed for congenital and acquired abnormalities. Consecutive sampling was performed.
A total of 72 patients (144 kidneys) were included in the study 57 being male and 15 female.
Abnormalities of renal vessels: accessory renal arteries 26 kidneys (18%), early arterial branching 17 kidneys (12%), right accessory renal vein 8 kidneys (6%), late venous confluence 20 kidneys (14%), left retro-aortic renal vein 2 kidneys (1%) and left circumaortic renal vein 2 cases (1%). 1 case had significant renal artery stenosis. Single collecting system was seen in 136 (94) cases and bifid renal pelvis in 8 cases (6%)
Simple cysts 4 kidneys (3%), calculus 2 kidneys (1%), and congenital anomalies 3 kidneys (2%) (2 fused horse shoe kidneys, 1 malrotated) 1 cortical scarring and 1 suspected lesion for malignancy.
Significant abnormalities not related to urinary tract: bronchial atresia 1 case, fused lumbar vertebrae 1 case, compressed fracture of lumbar vertebra 1 case and cholecystectomy in 1 case.
Significant variations are seen in renal vasculature which can be well evaluated by MDCT as a non-invasive imaging approach in probable renal donors.
