BobAug14Q. I’m in my 23rd year as a T9 para. I manage my bladder with intermittent catheterization, drink plenty of water and cath at least four or five times a day to make sure my bladder doesn’t get too full. I rarely had problems with bladder infections until recently. Over the past few years it seems like I’m fighting one after another. I try to flush them by drinking extra water, but more often than not, I end up on a course of antibiotics, which messes with my gut.

In a previous Para/Medic you wrote about an antibiotic called Neosporin G.U. that goes directly into the bladder and can be used on a daily basis. A friend’s urologist has him on a similar system, but it’s a mixture of saline and Gentamicin — he says it has kept UTIs at bay. Does one solution work better than another? And if you use them regularly, do they contribute to antibiotic resistance?

A. Good questions, Jeff. This is a topic that appears quite a bit on SCI-related sites, including CareCure Forum and, which discuss a myriad of solutions that can be added via catheter to the bladder to help reduce UTIs. The solutions can be added during clean intermittent catheterization (CIC) by way of a 60cc syringe that fits into the end of the catheter, or in the case of a suprapubic catheter or indwelling Foley, adding the solution and clamping the catheter for 20 minutes.

To track down answers, I turned to Dr. Michael Kennelly, director of urology at Carolinas R
