acute tubulointerstitial nephritis
chronic tubulointerstitial nephritis |
|
|
Term
1. account for 65-70% of all renal masses, are benign and require no tx unless cyst is complex. common with age.
2. increased # of cysts in CKD/ESRD pts. 2-7% develop in renal cell cancer |
|
Definition
1. solitary cysts
2. acquired cystic disease |
|
|
Term
- accounts for 4-5% of all end-stage renal disease in the US - slowly progressive - as cysts grow, they take up more space and the kidneys can't work - screen family members in their 2nd-3rd decade - cysts probably won't be big enough to pick up before then - associated with cerebral aneurysms and hepatic cysts - most commonly presents in 3rd and 4th decades with FLANK PAIN/BACK PAIN AND RENAL FAILURE OR HTN OR HEMATURIA
