MATERIALS AND METHODS: One hundred patients with lower urinary tract symptoms were instructed to keep a 3-day voiding diary. Patients were instructed to record the time and volume of their water intake, voided urine volume, and number and time of sensation of urgency and episodes of urge incontinence. Patients were diagnosed according to their clinical findings as having a normal bladder, hypersensitive bladder, overactive bladder, polydipsia polyuria, or nocturnal polyuria. Thirty-six patients underwent a urodynamic study to further assess their lower urinary tract dysfunction, for which urodynamic results were classified as a normal bladder, detrusor overactivity, or bladder hypersensitivity.
