ABSTRACT

Background: Anatomical knowledge of renal dimensions and arrangement of renal hilar structures is important for urological surgical procedures. The study on renal dimension and detailed information on structural arrangement of hilum is important to distinguish between the pathological kidney from normal sized healthy kidneys and also essential prior to any surgical interventions of kidney.

Materials and Methods: 64 (32 right and 32 left) embalmed kidneys from department of anatomy, MVJ Medical college and Hospital were utilized for the study. The morphometric measurements such as length, weight, width of kidneys at the superior and inferior pole, thickness at superior, middle and inferior pole were measured. Mean and standard deviation of   all parameters were noted. Hilar region was dissected and antero posterior arrangement of structures entering and leaving the hilum is noted.

Result: The length of kidney on right and left side is 8.9+/-1.58 cm and 9.01+/-0.88cm respectively. The weight of right kidney is 120.8+/-28 gm and left kidney is 123.45+/-30. 7gm.The mean and standard deviation of thickness and width of each kidney at superior and inferior pole is calculated. The antero posterior arrangement of structures at the renal hilum showed great variations. We classified these variations into 5 types. Typical pattern of hilar arrangement with renal vein, renal artery and pelvis was more predominant seen in 31.24% of specimens followed by Type 4 with renal vein, anterior division of renal artery, pelvis and posterior division of renal artery was seen in21.87% of specimens.

Conclusion: The knowledge of renal dimensions and hilar structure and its variations are important in case of renal transplantation, renal surgeries, radiological interventions, gonadal color Doppler imaging in surgeries of aneurysm of abdominal aorta. Hence the detailed knowledge of renal dimensions and hilar structural arrangement is essential for surgeons and radiologist to avoid any clinical complications in the abdominal region while performing the surgical procedures.

Key words: Renal hilum, pelvis, renal artery, renal vein, surgical interventions, renal transplantation, aneurysm, abdominal aorta.
