This operation was designed for patients considered too unstable to undergo laparotomy (LAP). Since the introduction of PD some investigators have suggested that it may serve as a definitive(More)
Gentamicin was administered intravenously or intramuscularly to 165 patients with non-obstructive urinary tract infections. 3 prospectively randomised groups were formed in which gentamicin was given either once daily (120 mg), twice daily (40/80 mg) or three times daily (40 mg). Clinically and bacteriologically an equally good improvement of the condition(More)
