INTRODUCTION: The advent of more conservative methods of treatment for renal pathologies has necessitated a precise knowledge of renal pelvicalyceal system. AIMS AND OBJECTIVES: 1. To study the anatomical variations in the pelvicalyceal pattern in human kidneys. 2. To analyse the various dimensions of lower pole infundibulum of kidneys. 3. To compare and correlate the dimensions with clinically significant parameters. MATERIALS AND METHODS: Human kidneys belonging to both sexes were collected from dissection cadavers in the department of anatomy, Thanjavur Medical College and autopsied bodies in the department of Forensic Medicine, Thanjavur Medical College. Various patterns of the pelvicalyceal system along with morphometric dimensions of the infundibulum which leads from the major calyces to the renal pelvis were studied. The result was then correlated with clinically significant parameters. RESULTS: The renal pelvis was intrarenal in position in majority (79%) of specimens and the type AI was more common when classified according to Sampaio’s classification. An interesting variation of extrarenal calyces with absent pelvis was observed in one specimen in the present study. The lower pole calyceal distribution was 2.41± 0.81. The common pattern of drainage of lower pole minor calyces was simple pattern (51%). The lower pole infundibular length had a mean±S.D value of 17.5 ± 3.4 mm. The infundibular width had a mean value of 5.63±2.2 mm. The mean value of length by width ratio was 3.6±1.5. The mean value of infundibular height was 12.5±3.93 mm. The mean infundibulo pelvic angle was 94.7±11.61 degrees. CONCLUSION: The varying patterns of the collecting system of the kidney must be taken into consideration while examining a radiological report of a patient with pathologies involving the kidneys. This is because for many pathologies, the treatment procedure involves approaching the area involved through the calyces. The difference in pelvicalyceal patterns and variations in different parameters help urologists and radiologists in choosing the right mode of treatment for the patients. This is not only helpful in reducing post procedural complications but also in minimising the economical burden upon the patients.
