Aim of study euromodulation of the sacral root represents a valid therapeutic option in the treatment of lower urinary tract disfunction. However, it is necessary to study the prognostic factors which influence clinical results of Sacral Neuromodulation (SNM). The aim of this study is to compare the results of SNM in two groups of female patients one with and one without previous pelvic surgery in order to identify if this could be useful as a prognostic factor.

Methods orm May `98 to March `99 the data of 39 implanted patients was analyzed. Of this 39 the 21 female subjects (mean age 49 range 19-71, mean follow-up 6.6 months) suffering from detrusor instability and/or ritention were selected for this study, 9 of them (42.8%) had undergone previous pelvic surgery, in 5 pts was performed a bladder suspension in 4pts was performed isterectomy. In this group of patients for 5 pts SNM was performed for detrusor instability and for the other 4 pts for urinary retention. In the other group (12pts) who had not undergone previous pelvic sugery SNM was performed in 7pts for detrusor instability and in 5 pts for ritention. A form was developed to collect the data which includes the following fields: indication for surgery together with type and clinical results. To assess if there are differences between the two groups a t-test was performed.
