Another consequence of this procedure is an increased risk of kidney infections (nephritis) due to bacteria from faeces travelling back up the ureters (reflux).
Several conditions may evoke blood pressure elevation: acute nephritis, eclampsia, crises in chronic essential hypertension, sudden withdrawal of antihypertensive treatment.
They noted that chronic users of phenacetin had an increased risk of developing specific kidney injuries, namely renal papillary necrosis and chronic interstitial nephritis.
The inflammation of the renal tissues (interstitial nephritis) can produce leukocyturia, in particular toxic interstitial nephritis with predominant eosinophils.
