Further observations on self-catheterization.

A non-sterile technique of intermittent self-catheterization was used for 218 patients with an inability to void in a normal fashion because of obstructive uropathy, decompensated detrusor or neurogenic bladder. Marked improvement was not in urinary continence, urinary infection, renal function, bladder emptying and, perhaps most important, the mental and emotional status of the patient and/or parents. The extremely low incidence of complications and its therapeutic efficacy clearly make clean, intermittent self-catheterization an outstanding weapon in the urological armamentarium and a most persuasive reminder that host resistance is still the primary factor in the occurrence of infection.
