摘要

OBJECTIVE: Voiding diary is an indispensable part of lower urinary tract assessment. The aim of this study was to evaluate the correlation of clinical diagnoses made using 3-day voiding diaries with urodynamic results.
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. The clinical diagnoses and urodynamic results were correlated.
RESULTS: Among these patients, 75 (75%) had a variability of ± less than 2 times per day in voiding frequency within the 3 days. Twenty-four patients (24%) had nocturnal polyuria, increased bladder sensation was noted in 36 patients, and overactive bladder was noted in 56 patients. Among the total patients, 62 had reduced bladder capacity, whereas 38 had a normal bladder capacity. Among the 38 patients with a normal bladder capacity, 12 (31.6%) had an overactive bladder, whereas among the 62 patients with reduced bladder capacity, 44 (71%) had an overactive bladder (p ＜ 0.05). Urodynamic detrusor overactivity was found in 7 (36.8%) of 19 patients who had a clinical diagnosis of an overactive bladder and in 7 (41.2%) of 17 patients without a clinical diagnosis of an overactive bladder (P＞ 0.05).
CONCLUSIONS: This study shows that a 3-day voiding diary is helpful in diagnosing lower urinary tract symptoms. Voiding diaries using 3 days of records have a good reproducibility rate and little variability. However, neither voiding diary nor urodynamic study can reflect the maximum bladder capacity or detrusor overactivity.
