Analysis Of Morphology Of Renal Calyceal Pattern In Renal Donors Using Ct Angiography

Abstract

Transplants are one of the biggest achievements of modern medicine and can save or greatly enhance the lives of other people. The recovery period after laparoscopic surgery is quicker than open surgery. It is important to know the variations of the renal calyceal pattern prior to the laparoscopic surgery during renal surgeries. The aim is to analyze the calyceal system in kidney donors using 64-Slice Computed Tomography Angiography. The study was conducted in a specialized scan centre located in Chennai after getting appropriate permission and ethical clearance. The study group was drawn from kidney donors who approached the scan centre and had no diseases related to kidney.  In this study,  a total of 99 healthy kidney donors were included  to study the pattern of pelvicalyceal pattern and to classify further into bi-calyceal, tri-calyceal and multi-calyceal. This study found that bi-calyceal pattern is the most common pattern (%) and further this pattern was more in the right side in males and left side in females. The numbers of minor calyces were significantly more in the right multi-calyceal pattern than left multi-calyceal, tri-calyceal and bi-calyceal patterns. The association of occurrence in these pattern was significant in males with a strong association and insignificant in females. A detailed description of intrarenal arterial pattern and its relationship with calyceal pattern will be great significance in renal transplantation and also for other urological procedures.
