I am retaining too much urine with very high residuals of 500- 700 cc s . I have had a cystoscopy, a TURP and was told by the Dr. to loose weight and exercise and will be having some urodynamic testing done in about 2 months. I have been doing self caths 2-3 times a day and to continuue with this. I am finding this extremely frustrating and wondering if more can be done. The Dr. said it may be permanent.
