Horseshoe kidney in an 80 year old with chronic kidney disease

Fused ureters in patient with horseshoe kidney and aortic abdominal aneurysm

Horseshoe kidney (HSK) is a very common developmental abnormality in the kidney. They are associated with abnormalities like multiple renal arteries, abnormal position of the ureter in the renal pelvis and highly placed ureteropelvic junction. These can result in urological complications. However, the ureters run their separate course and empty individually into the urinary bladder. Surprisingly, anatomical anomalies do occur and can lead to unexpected findings on investigation or surgical treatment. Such anomalies can present diagnostic and management challenges to unsuspecting clinicians. This report deals with one of such anomalies that seem not to have been reported before in the literature. This case is a rare finding of fused ureters over the renal isthmus in a patient with HSK who also has aortic abdominal aneurysm (AAA). Simultaneous occurrences of HSK and AAA have been reported severally in the past, and the authors are paying attention on the ureteral anomaly.
