A prospective, randomized controlled study comparing lidocaine and tramadol in periprostatic nerve blockage for transrectal ultrasound-guided prostate biopsy.
To assess the efficacy of tramadol and lidocaine in reducing pain using the periprostatic nerve block technique with a spinal needle, guided by transrectal ultrasound (TRUS) before the biopsy application. ⋯ In this study, we showed that the local anesthetic effect of tramadol in decreasing pain in periprostatic nerve block during TRUS-guided biopsy. The use of tramadol for pain relief in transrectal ultrasound-guided prostate biopsy is a practical, effective, and comfortable method compared with the results of the control group.

To determine whether Internet search volume for kidney stones has seasonal and geographic distributions similar to known kidney stone incidence. ⋯ Internet search volume activity for kidney stones correlates with temporal and regional kidney stone insurance claims data. In the future, with improved modeling of search detection algorithms and increased Internet usage, search volume has the potential to serve as a surrogate for kidney stone incidence.
