Acute Renal Failure Caused by Upper Urinary Lithiasis Obstruction in Children

Abstract

Objective To review the efficacy of operative treatment for acute renal failure resulted from obstruction of upper urinary lithiasis.Methods Seventy-four cases(male 51,female 23)of acute renal failure caused by upper urinary lithiasis were admitted from 1985 to 1997.The age ranged from 4 months to 11 years(mean 2 yrs and 10 mons).Prompt drainge by insertion of percutaneous nephrostomy tube and ictus therapy with diuretic mixture were indicated until the clinical situation of renal failure improved.Results Among the 74 patients(kidney 62,ureter 19,bladder 3),who underwent surgical removal of the lithiasis,67 survived and 7 died.Conclusions The operative management of adults with urinary lithiasis is also fit for children.When patients with bilateral lesions,the general situation will be reversed by unilateral releasing from the obstruction.The function of the contralateral kidney after an selective operation is still kept well.
