Accordingly, this study was designed to evaluate the prevalence of anatomical and developmental abnormalities of ureters and renal pelvis existing with accessory renal arteries in human cadavers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>This study was carried out on 50 human cadavers including dissected specimens (25 males and 25 females) the kidneys, renal pelvis, and ureters along with their arteries were exposed and the anomalous abnormalities of the renal pelvis and ureters existing with accessory renal arteries were observed.

Interestingly, this prevalence was higher among males (28%) compared to females (8%). Moreover, the occurrence of bilateral hydronephrosis of the kidneys, renal pelvis, and ureters was identified in a single male cadaver, representing 2% of the sample. Notably, the prevalence of double ureter, hydronephrosis accompanied by congenital double and triple accessory renal arteries was documented in nine cadavers, accounting for 18% of the cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Anatomical and developmental variations of the ureters, renal pelvis, and renal vasculature, as well as their relationships to surrounding structures, hold clinical significance due to their impact on various surgical procedures, including kidney transplantation, abdominal aorta reconstruction, interventional radiology, and urologic operations. Therefore, identifying these potential developmental variations is essential for effective surgical management to preserve renal function and ensure optimal patient outcomes.<\/jats:p>\n
