Urethroplasty for high risk, long segment urethral strictures can be successfully performed with a ventral buccal mucosa graft and a gracilis muscle flap, avoiding urinary diversion in most patients.
To our knowledge this is the first study demonstrating urethral reconstruction using a rectal mucosa graft harvested by the transanal endoscopic microsurgical technique. Initial data revealed that this technique is feasible and safe, and minimizes graft harvest morbidity. Transanal endoscopic microsurgical harvest of a rectal mucosa graft may provide an alternative graft material for patients with long segment urethral strictures who are not candidates for oral mucosa graft harvest. Further experience and longer followup are needed to validate these findings.
This study identified miRNAs differentially expressed in ccRCC samples; as well as those correlating with CSS. Biomarkers identified in this study have the potential to identify patients who are likely to have progressive ccRCC, and although preliminary, these results may aid in differentiating aggressive and indolent ccRCC based on biopsy specimens.
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.
