analgesic nephropathy  interstitial nephritis with renal papillary necrosis, seen with abuse of analgesics such as aspirin or acetaminophen.

diabetic nephropathy  the nephropathy seen in later stages of diabetes mellitus, with first hyperfiltration, renal hypertrophy, microalbuminuria, and hypertension, and later proteinuria and end-stage renal disease.

gouty nephropathy  any of a group of chronic kidney diseases associated with the abnormal production and excretion of uric acid.

IgA nephropathy

Berger's disease, IgA glomerulonephritis Nephrology Idiopathic IgA nephropathy is the most common form of primary glomerulonephritis in the world; primary IN is mediated by immune complexes and defined immunohistochemically by glomerular deposition of IgA; in 20-40% of Pts, it progresses to renal failure 5-25 yrs after diagnosis; IN may occur in HIV-infected Pts Clinical Macroscopic hematuria which may coincide with an URI and be accompanied by flank pain, a presentation typical of younger Pts; older Pts tend to be asymptomatic and IN is detected by sediment and proteinuria Treatment ACE-inhibitors, corticosteroids, n-3 polyunsaturated fatty acids provided in dietary fish oil may slow progression of renal failure, kidney transplantation Prognosis More rapid progression occurs in ♂, older Pts, HTN, persistent proteinuria, baseline of impaired renal function, glomerulosclerosis or interstitial fibrosis at the time of initial evaluation
