Abstract

Post-obstructive diuresis after treatment for neurogenic bladder-induced obstructive kidney disease is a common symptom. As polyuria may develop in many other conditions as well, the present case is about a patient with a chief complaint of polyuria accompanied by nocturia, that was initially diagnosed as hydronephrosis due to the presence of neurogenic bladder and bladder dysfunction. The result of the water deprivation test, which was conducted for persistent diluted polyuria, yielded a final diagnosis of central diabetes insipidus, notwithstanding the strong impression of post-obstructive diuresis initially made because of a sudden increase in urine output after an indwelling catheter was inserted for bladder decompression.
