| Renal ectopia has to be differentiated from the following: | | Horseshoe kidney disease must be differentiated from Renal ectopia, Ureteropelvic junction obstruction, Hydronephrosis and Duplicate collecting systems. |
| | ==Differentiating Horseshoe kidney from other Diseases== |
| | Horseshoe kidney has to be differentiated from the following: |
| * Hydronephrosis | | * Hydronephrosis |
| * Ureteropelvic junction obstruction | | * Ureteropelvic junction obstruction |
| * Duplicate collecting systems, ovarian cysts | | * Duplicate collecting systems, ovarian cysts |
| * Mesenteric cysts | | * Renal ectopia |
| * Sacrococcygeal teratoma. | | * Pan cake kidney or disc kidney |
| The main differential diagnosis of HSK is another variety of renal ectopia known as pancake kidney, disc kidney or shield kidney. There is a complete midline fusion of the kidneys at the pelvis.<ref name="DyerChen2004">{{cite journal|last1=Dyer|first1=Raymond B.|last2=Chen|first2=Michael Y.|last3=Zagoria|first3=Ronald J.|title=Classic Signs in Uroradiology|journal=RadioGraphics|volume=24|issue=suppl_1|year=2004|pages=S247–S280|issn=0271-5333|doi=10.1148/rg.24si045509}}</ref> It is always found below the L2 vertebral body and is frequently associated with vascular abnormalities of the aortic branches | | The main differential diagnosis of HSK is another variety of renal ectopia known as pancake kidney, disc kidney or shield kidney in which there is complete midline fusion of the kidneys at the pelvis.<ref name="DyerChen2004">{{cite journal|last1=Dyer|first1=Raymond B.|last2=Chen|first2=Michael Y.|last3=Zagoria|first3=Ronald J.|title=Classic Signs in Uroradiology|journal=RadioGraphics|volume=24|issue=suppl_1|year=2004|pages=S247–S280|issn=0271-5333|doi=10.1148/rg.24si045509}}</ref> It is usually seen below the L2 vertebral body and is frequently associated with vascular abnormalities of the aortic branches. |

| ==Differentiating [Disease name] from other Diseases==
| |
| [Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
| |
| | |
| OR
| |
| | |
| [Disease name] must be differentiated from [differential dx1], [differential dx2], and [differential dx3].
| |
| | |
| OR
| |
| | |
| As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].
| |
| | |
| ===Differentiating [disease name] from other diseases on the basis of [symptom 1], [symptom 2], and [symptom 3]===
| |
| | |
| On the basis [symptom 1], [symptom 2], and [symptom 3], [disease name] must be differentiated from [disease 1], [disease 2], [disease 3], [disease 4], [disease 5], and [disease 6].
