Association between severity of schizophrenic symptoms and urinary retention.

A case is presented in which severe urinary retention (UR) occurred during an acute psychotic exacerbation of paranoid schizophrenia. The voiding dysfunction was apparent during continuous treatment with unchanged doses of haloperidol, and it completely resolved with the remission of the psychotic symptoms. A clear temporal correlation was evident between the patient's mental status, the Brief Psychiatric Rating Scale (BPRS) score and the degree of the UR as assessed by quantitatively measuring the total daily post-voiding urine residues. We could not relate the UR to any apparent general medical condition or to the haloperidol treatment. The presented data suggests that UR in schizophrenic patients might be the end-result of various psychosis-related mechanisms.
