3D T2-weighted MRI has been increasingly utilized for pelvic applications, including imaging of rectal cancer, prostate cancer, anorectal fistulas and the female pelvis. This relatively rapid technique offers good soft-tissue contrast of the pelvic organs, with potential for more widespread clinical use.
Intercostal vessels are at risk for damage during percutaneous nephrostolithotomy in a significant number of patients. Access placement lateral to the paraspinous muscles and in the lower half of the 11th intercostal space may decrease damage to the intercostal artery and nerve. Injury to the intercostal vessels and nerve may explain the increased risk of bleeding and pain during supracostal percutaneous nephrostolithotomy. Minimizing injury may decrease blood loss and pain.
Bone wax is an effective hemostatic agent that generally is considered safe. However, because it is nonabsorbable, significant complications can occur. We present the first two reported cases of delayed migration and extrusion of bone wax through postauricular wounds due to foreign body reaction and granuloma formation following mastoid surgery. We also present a literature review of complications associated with intraoperative bone wax use and discuss alternative hemostatic agents. Laryngoscope, 128:369-372, 2018.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
