I have urinary retention after bladder sling surgery. doctor tried to surgically fix it but still can not void. what can i do?

Second opinion: Releasing the sling is a simple procedure and should have worked. It often results in leakage again but not always. The only time i've seen this in a patient w/o a preexisting problem that did not reapond to release was when the patient was very anxious. This will require further evaluation by a doc who has more experience with slings than it sounds like yours might after releasing i'd stretch it.
