Cindy, Rarely but we have done them in isolated instances. We do not have a physician present but they are usually on stand-by waiting to see if we are successful. If the compression doesn't work, they'll come in to do an injection. There's been a time or two where the physician wasn't available right away, the patient could tolerate the probe pressure, I thought the PSA would respond to compression, the sun and moon and stars were aligned just right.... I've done maybe 5 in the last 5 yrs. Jill To unsubscribe or search other topics on UVM Flownet link to: http://list.uvm.edu/archives/uvmflownet.html
