Renal fusion anomalies (excluding horseshoe kidney)

Renal fusion anomalies, excluding the well-known horseshoe kidney, encompass a range of congenital conditions where the kidneys are abnormally connected.

These anomalies can include crossed fused renal ectopia, where one kidney crosses to the opposite side and fuses with the other, leading to a single mass that may have two distinct ureters.

In these conditions, the fusion typically occurs during fetal development when the kidneys ascend from the pelvis to their usual position in the abdomen.

When the ascent is disrupted, fusion anomalies can result, which may affect kidney function depending on the structure and blood supply involved.

These anomalies are generally asymptomatic but can sometimes lead to complications such as urinary tract infections, stones, or obstruction due to abnormal ureteral positioning.

Detection is commonly achieved through imaging techniques such as ultrasound, CT scan, or MRI, which are encompassed by Torso scans, as these allow visualization of the abdominal organs.

Understanding renal fusion anomalies is essential for accurate diagnosis and management, ensuring that potential complications are promptly addressed.

Regular monitoring and follow-up can help manage any functional impairments that may arise due to these anatomical variations.
