I just found this thread that's been going on now for 2 years. I have been recently diagnosed with urinary retention caused by radiation treatment for prostate cancer and am also looking for solutions other than self-catheterizing 4 times a day. I have seen it mentioned that pelvic floor exercises can help, but I haven't seen any success stories or any specifics on which exercises are best for urinary retention. Most seemed to be focused on the opposite issue, leakage.

Has anyone had any success?
