Does preoperative urodynamics change the management of prolapse?

The objective of this study was to evaluate whether preoperative urodynamics (UDS) changed the management of patients undergoing prolapse surgery, and if so in what way. A retrospective study of 72 randomly selected cases was conducted. We assessed which women undergoing prolapse surgery were more likely to undergo UDS and in what way UDS altered management. SPSS version 13 was used to analyse the data. A total of 60% (43/72) of the patients underwent preoperative UDS and 53% (23/43) of the women undergoing UDS had an abnormal result with prolapse reduction; 19% (8/43) had pure urodynamic stress incontinence; 30% (13/43) had detrusor overactivity either in isolation or as mixed incontinence. The surgical management was altered in 7% (3/43), who had an additional continence procedure performed as a consequence of the UDS. Preoperative UDS changed management in 33% (14/43) patients and in 7% (3/43 undergoing UDS) of patients, the surgical procedure was changed.
