We have used BTX injections into the sphincter to relieve the obstruction and allow patients to maintain spontaneous voiding rather than intermittent catheterization.

While narrow excision is the gold standard for melanoma diagnosis, superficial shave biopsies have become the preferred method by dermatologists but may transect the lesion and result in inaccurate Breslow thickness assessment. This is a retrospective cohort study evaluating an initial method of biopsy for diagnosis of cutaneous melanoma and indication for reoperation based on inaccurate initial T-staging.
