Spatial distribution of biopsy cores and the detection of intra-lesion pathologic heterogeneity.

Objectives: The objective of this study was to determine if spatial distribution of multiparametric magnetic resonance imaging-transrectal ultrasound (mpMRI-TRUS) fusion biopsy cores to the index lesion reveals trends in the detection of intra-lesion Gleason heterogeneity and a more optimal prostate biopsy strategy.

Methods: Index lesion was the lesion with longest diameter on T2-weighted (T2W)-MRI. In cohort 1, fusion biopsy cores biopsies were taken in areas in the center of the target as well as 1 cm laterally on each side.

Clinical Influences in the Multidisciplinary Management of Small Renal Masses at a Tertiary Referral Center.

Introduction: We designed a multidisciplinary Small Renal Mass Center to help patients decide among treatment options and individualize therapy for small renal masses. In this model physicians and support staff from multiple specialties work as a team to evaluate and devise a treatment plan for patients at the same organized visit.

Methods: We retrospectively reviewed the records of 263 patients seen from 2009 to 2014.

Risk factors for biochemical recurrence after robotic assisted radical prostatectomy: a single surgeon experience.

Background: Radical prostatectomy is a standard surgical treatment of clinically localized prostate cancer. Margin status has been found to be an independent predictor of biochemical recurrence (BCR) after open radical prostatectomy in several large series but this is still controversy in Robotic Assisted Radical Prostatectomy (RARP) series. We therefore wanted to investigate the prognostic significance of positive surgical margin (PSM) and other pathological factors on BCR in patients treated with RARP by a single surgeon.

Implementing hexaminolevulinate HCl blue light cystoscopy: a nursing perspective.

Hexaminolevulinate HCl is a diagnostic imaging agent used with blue light during cystoscopy to help detect non-muscle-invasive bladder cancer. Blue light cystoscopy performed using hexaminolevulinate HCl has been found to detect more papillary non-muscle-invasive bladder tumors than cystoscopy performed using standard white light. Because bladder instillation and retention requirements of hexaminolevulinate during cystoscopy can affect patient flow in the perioperative setting, this technique necessitates changes in nursing practice and care of patients with known or suspected non-muscle-invasive bladder cancer.

Predictors of positive surgical margins after radical prostatectomy at a single institution: preoperative and pathologic factors, and the impact of surgeon variability and technique on incidence and location.

Introduction: To identify and assess predictive factors for positive surgical margins (PSM) in patients undergoing radical prostatectomy (RP).

Materials And Methods: An Institution Review Board (IRB) approved retrospective review of 1751 patients that underwent RP from March 2000 to June 2013 was performed. Identified were 1740 patients whom had not received neoadjuvant therapy; these were used for the purpose of this analysis.
