Endoscopic Third Ventriculostomy in 250 Adults With Hydrocephalus: Patient Selection, Outcomes, and Complications.

Background: Endoscopic third ventriculostomy (ETV) has been used predominantly in the pediatric population in the past. Application in the adult population has been less extensive, even in large neurosurgical centers. To our knowledge, this report is one of the largest adult ETV series reported and has the consistency of being performed at 1 center.

Prostate biopsy volume predicts final tumor volume.

Aim: To assess the ability of prostate biopsy volume to effectively predict actual tumor volume, and whether increasing the number of prostate biopsy cores improves the ability to forecast actual tumor volume.

Methods: 765 patients who underwent robotic radical prostatectomy (2009-2010) were identified. Of these, 663 had complete demographics, biopsy, and final pathology data available.
