159 kidneys from infant and neonatal cadavers were dissected under stereoscope.The study showed that there were a lot of lymphatics(11.11?2.48) originating fromthe lymphatic network of renal sinus.The lymphatics of renal pedicle variedslightly in diameter (0.25-0.40 mm).The mean value of the diameter oflymphatics in the renal pedicle was 4mm.The mean value of the ratio ofdiameter of lymphatics to that of renal vein on the same side is 90.47%.Therewere positive correlation between them.The renal lymph nodes were scattered singlyin number in each kidney.
