“…Variations in the ramification patterns of renal and testicular vessels have been reported in detail, particularly with respect to their possible number, origin, course, and termination [8,20,23,25,27]. However, such mutations sometimes occur simultaneously and in various combinations, and may be accompanied by malformation in the kidney and urinary tract [1,2,9,11,13,18,21,26,28]. Compared to a single variation, the presence of multiple variations increases the risk of unexpected injury to the urogenital vessels during surgical procedures; therefore, a detailed description of combined variations is helpful to ensure safe surgery.…”
