Previous research has shown that the administration of 2% alkalinized lidocaine in the bladder may improve the bladder's capacity to hold urine and urine flow rates while simultaneously providing pain relief. As part of standard of care at the Smith Institute of Urology Pelvic Pain Center, we routinely offer our IC patients 2% alkalinized lidocaine with follow up urodynamic evaluation. Our research looks to expand upon the prior studies and confirm the findings of improved bladder function and enhanced pain control of 2% alkalinized lidocaine versus placebo by performing a second urodynamic evaluation, which is not routinely performed.
