Post-obstructive diuresis.

Abstract

A patient with post-obstructive diuresis is described. Inappropriate losses of salt and water occurred, with urine volume exceeding half the glomerular filtration rate. Additionally, excessive urinary excretion of potassium, bicarbonate, calcium, phosphate, magnesium and urate took place in the presence of subnormal blood levels. Transient proteinuria was also observed. This case demonstrates that serious electrolyte disturbances can occur after relief of urinary tract obstruction and the evidence suggests these may be due to disordered proximal tubule function.

Renal excretory profiles of loop diuretics: consequences for therapeutic application.

In healthy subjects, 24-h natriuresis, kaliuresis, calciuresis, and magnesiuresis increase in response to the first oral dose of a standard (diuretic) formulation of a loop diuretic, such as furosemide 40 mg. However, low-dose formulations of loop diuretics, such as torasemide 2.5 mg, do not elevate 24-h natriuresis after the first dose is administered to normal individuals who are in steady-state habitual sodium balance; these formulations of loop diuretics are consequently labeled as nondiuretic formulations (of diuretic substances). Nondiuretic formulations of loop diuretics do not increase the 24-h urinary outputs of sodium, potassium, calcium, or magnesium after the first dose or in the course of repeated once-daily administration to healthy subjects. The 24-h natriuretic response to the first dose of standard (diuretic) formulations of loop diuretics wanes during repeated once-daily administration to healthy individuals, whereas the kaliuretic response becomes slightly attenuated, and calciuresis and magnesiuresis bear little change. Once-daily treatment with any formulation of a loop diuretic may result in an increase in plasma urate concentration. Nondiuretic formulations of loop diuretics, which are efficacious as once-daily monopharmacotherapy for high blood pressure, should be tried before standard (diuretic) formulations of diuretics are used in the treatment of uncomplicated essential hypertension. When loop diuretics are employed in the treatment of congestive heart failure, the minimal dose compatible with the attainment of clinical objectives should be used.

Unilateral post-obstructive diuresis in the neonate.

A total of 3 neonates exhibited severe post-obstructive diuresis after relief of unilateral ureteral obstruction. Of the neonates 2 had normal kidneys contralaterally while 1 had a contralateral kidney that was dysplastic. Urinary output exceeded oral intake initially in all 3 patients necessitating intravenous supplementation for up to 10 days. Stabilization resulted from an increase in oral intake rather than a decrease in diuresis. Unilateral post-obstructive diuresis is extremely uncommon but it may occur in the neonate because of the unique features of the renal physiology encountered in this age patient.
