Table 2 Grading of the urodynamic study parameters by Meyrat et al. [17]. The 4 parameters that were included were: 1. Bladder volume 2. Compliance 3. Detrusor activity 4. Vesico-sphincteric synergy/Detrusor sphincter dyssynergia (DSD). Classification of UDS is as follows: 0 to 4 is normal, 5 and 6 raises question of neuro-urological disorder and needs to be repeated, more than 6 is abnormal
Grade | Parameters | |||
|---|---|---|---|---|
Bladder volume | Compliance | Detruser activity | Vesico-sphincteric synergy | |
0 | > 100 | > 25 | Normal | Synergy |
1 | 80–99 | 20–24 | Frequent contractions in all phases | Lack of relaxation |
2 | 60–79 | 20–24 | Systole end phase 2 | Intermittent dyssynergy |
3 | 40–59 | 15–19 | 1 + 2 | Continuous dyssynergy |
4 | 20–39 | 10–14 | Few systoles in all phases | |
5 | < 20 | < 10 | Frequent systoles in all phases | |
