Urinary Retention after Prostate Radiation

Posted by ddewitt @ddewitt, 6 days ago

My husband developed urinary retention after prostate radiation. He is self catherizing. Have gone to several urologist with no solution. Is there any device that can help. Should he see a Nuerologist. He had to be hospitalized to drain bladder. Please seeking any suggestion.

I would also add that a radiation machine that has a built-in is significantly more accurate than one that does not, and it’s been proven in the mirage randomized trial study. This study showed that side effects and toxicity were much less when that type of radiation machine was used because the margins were smaller, so there was less healthy tissue exposed.

@bens1 Did you mean to say built-in MRI? I had my 2nd of 5 treatments yesterday, with an MRI-guided Elekta machine.

@vircet yes, thank you. Built in MRI.

Did that Elekta have auto shutoff if the radiation got outside of the mapping? Where did you get treated?

@bens1 According to literature, Elekta machines have auto shut off. There is the Elekta MR-Linac (there are very few of them in Ontario-& Quebec-Canada, compared to the older generation Elektas) but I was told that it's used only for patient's with high risks of healthy organ damage (e.g., prostate cancer patients who cannot have the gold seeds fiducial markers implanted). I have gold seeds.

@vircet thank you. I know there is an Elekta Unity MR Linac at UF Health Radiation Oncology - Davis Cancer Pavilion in Gainesville, FL but I have not heard of any restrictions regarding its use in prostate cancer related to fiducials.

The stronger real time imaging results is a plus.

@bens1 I don't think it's necessarily a restriction in use related to fiducials. It seems to me that the cancer center decided to use the MR-Linac for patients who have greater risks due to inability to have the fiducial markers implanted, or other complex issues. If the cancer center retired all their older Elektas, and every patient lined up to the MR-Linac, the waiting time for treatments will be very long. I would have preferred the Linac, but my RO assured me that they have tested all their Elektas and they are all good.
