A Case of Chronic Renal Failure in a Polydipsic Schizophrenic Patient caused by Chronic Anticholinergic Therapy / 대한신장학회지

Anticholinergic drugs block muscarinic receptors at the detrusor muscle of the bladder. It can cause urinary retention by contracting the bladder neck. Cases of hydronephrosis, bladder dilatation as a result of polydipsia while taking anticholinergic drugs have been reported, but very few cases of chronic renal failure can be found. We report a case of a polydipsic schizophrenic patient who, after taking anticholinergic drugs as antipsychotic drugs to treat his schizophrenia for a long time, presented with chronic renal failure due to functional obstructive uropathy in the absence of demonstrable anatomic causes of obstruction.
