Overview
Most people with horseshoe kidneys are totally asymptomatic and their kidneys function normally throughout their lives. About quarter of cases are found incidentally, usually during a CT scan due to some other problem. Nonetheless, there are lots of other patients who are predisposed to certain medical sequelae due to the embrogenesis or intrinsic anatomical abnormalities.[1]
Pathophysiology
- Most people with horseshoe kidneys are totally asymptomatic and their kidneys function normally throughout their lives. About quarter of cases are found incidentally, usually during a CT scan due to some other problem. Nonetheless, there are lots of other patients who are predisposed to medical sequelae due to the embrogenesis or intrinsic anatomical abnormalities. These issues include:
- Ureteropelvic junction obstruction : It is the most common problem in horseshoe kidney. It is caused by crossing of ureter over the fused isthmus leading to its obstruction.
- Kidney Stones : Stones usually occur when there is obstruction leading to decreased urine output and stasis of urine which create environment for stone formation.
- Recurrent infections : Again due to stasis of urine, because stasis of urine create medium for bacterial growth
- Hydronephrosis : Basically it is caused by back-flow of urine due to obstruction of ureteropelvic junction.
- Increased incidence of certain cancers such as renal cell carcinoma, Wilm's tumor and Carcinoid tumors.[2]
