title: An alternative method for determining daily bladder perception.
abstract: OBJECTIVE
  To avoid the unphysiologic nature of cystometry, we searched a new tool for evaluating bladder perceptions.
  
  
  METHODS
  The study group consisted of 25 (14 girls and 11 boys) primary monosymptomatic enuretic children with a mean age of 11 (range 8-16). Four children were excluded due to neuromuscular dysfunctions of the bladder, which was demonstrated with the help of cystometry. All children filled a voiding chart 3 times daily to record the duration elapsed till normal desire (ND(daily)) and strong desire (SD(daily)). During cystometry, the amounts of infused medium (cystometric ND(ml) and cystometric SD(ml)) and the duration (cystometric ND(sec) and cystometric SD(sec)), till ND and SD were perceived and recorded.
  
  
  RESULTS
  Mean cystometric ND(ml) was 209.9 +/- 107.2 and ND(sec), 318.1 +/- 135.5, whereas mean cystometric SD(ml) was 273.0 +/- 103.1 and SD(sec), 415.7 +/- 136.8. To evaluate the reliability of elapsed time instead of milliliters, as a parameter, cystometric ND/SD values were calculated and a strong correlation was found between the 2 (ND/SD(sec) = 0.77 +/- 0.19 and ND/SD(ml) = 0.77 +/- 0.19, r = 0.9795, P = .000). Although there was a strong correlation between 3 ND(daily) (r = 0.9576, P = .000), between 3 SD(daily) (r = 0.9706, P = .000), and 3 ND/SD(daily) (r = 0.8706, P = .000), no significant correlation was determined between mean ND(daily) and cystometric ND(sec) (r = 0.3410, P = .2032), and also between mean SD(daily) and cystometric SD(sec) (r = 0.2740, P = .2402).
  
  
  CONCLUSIONS
  Daily durations of sensations do not correlate with those perceived during cystometry. However, as the results of 3 consecutive daily recordings have a strong correlation, comparison of the reliability of these methods is still needed.
