It may present as:
- sterile pyuria
- chronic renal failure
- renal pain (due to papillary necrosis)
An IVU will show 'cup and spill' calyces
Renal biopsy may show interstitial nephritis
Treatment is to stop the analgesics and managed any renal failure.
There is an increased risk of urothelial tumours.
