Hello and welcome to HCM. As an Urologist,i must assure you,there s nothing to worry about. Horseshoe kidney is just a congenital(by birth),variant of normal kidney. It s position is lower than the normal placed kidneys. Hence, instead of the kidneys being in the two flanks at the back, it s located in front lower part or pelvis. This abnormal location on the front side, doesn t affect function of kidney. Falling forwards on a hard object or sharp object has a potential threat of injury to the kidneys, which s easily made out on a scan.Hope you re relieved of your doubts. You can get my expert opinion, sending it as a direct question. Dr.Matthew J. Mangat.
