An appraisal of S3 blocks in the management of incontinence

Sixteen patients were treated for incontinence by S3 blocks when other means had failed. CMG had demonstrated detrusor instability in 14 and was not performed in 2 patients. Ten patients are continent, 2 are improved. There have been no complications or side effects. These results suggest that S3 blocks should be considered as an additional method of treatment of detrusor instability.
