| Back | Floor = inguinal lig and lacunar ligRoof = arching fibres of IO/TAPost = conjoint tendon (IO/TA), transversalis fasciaAnt = EO aponeurosis (IO lateral 1/3)Ilioinguinal nerve enters canal between IO & EODeep ring = transversalis fascia opening, located 1cm lateral to inferior epigastric vessels and 1cm above inguinal ligament |
| Front | Horseshoe kidney. Incidence? Blood supply? % with stones? Associations? |
| Back | 1/400 - 1/1000Blood supply is principally supplied by the renal arteries which arise from the aorta. Supply also from CIA. Variable ++. Single renal artery (30%) to each or ectopic Artery to isthmus is common (60% aorta, 30% IMA) Blood vessels posterior to the renal hilum70% stones –Urological •Infection •Stones •PUJ obstruction •Injury by blunt trauma •VUR •Malignancy –Non-urological •VSD •Turner •Down’s |
