Objective
To explore the relationship between subjective severity of symptoms of detrusor instability (DI) on presentation, outcome after treatment for DI and initial diagnostic urodynamic variables, with the aim of identifying a urodynamic variable which might, by predicting a favourable outcome from treatment, classify the severity of DI.
Patients and methods
Women with a urodynamically proven diagnosis of DI were recruited prospectively for the study. Data on disease symptoms and variables from their diagnostic cystometrogram were collected. All women were then treated and their outcome at 6 weeks after treatment compared with the initial urodynamic variables. Data on severity of symptoms were compared with initial urodynamic variables to explore any differences in these variables attributable to symptom severity.
Results
Of 300 women studied (mean age 54 years, sd 16), 290 were treated with oxybutynin and bladder retraining. At 6 weeks, 82 women had their treatment outcome classified as worse/no change; 218 women had improved. When good or poor outcome was compared with the urodynamic results, there was no significant difference between the groups. Likewise, the severity of symptoms did not relate to the values of urodynamic variables.
Conclusions
There was no statistically significant relationship between reported severity of symptoms and urodynamic variables, and no relationship between the urodynamic variables used and response to treatment. Therefore, using these values it is not possible to predict a favourable outcome from treatment or to use them to classify disease severity.

Thirty-eight isolates of Hafnia alvei were characterized by biochemical profiles, ribotyping and pulsed-field gel electrophoresis (PFGE) patterns. The isolates were recovered from chub-packed (19 isolates) or retail (nine isolates) ground beef, or were obtained from culture repositories (10 isolates). Biochemical profiling differentiated the 38 isolates into five groups and a commercial ribotyping method recognized 11 groups, whereas PFGE differentiated the same 38 isolates into 19 groups. These data substantiate that PFGE is a highly discriminatory tool for establishing the relatedness among Hafnia alvei strains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
