Renal Neuroendocrine Neoplasms: A Single-center Experience.

Background: Primary neuroendocrine neoplasms (NENs) of the kidney are exceedingly rare malignancies and the available literature is very limited. The natural history and response to treatments is not well characterized. We aimed to describe the presenting features, demographics, tumor characteristics, and treatment outcomes of patients with renal NENs.

Artificial urinary sphincter revision with Quick Connects versus suture-tie connectors: does technique make a difference?

Objective: To evaluate characteristics of artificial urinary sphincter (AUS) mechanical failures and compare outcomes based on the use of either suture-tied connections or Quick-Connects (QC) for single-component revisions.

Material And Methods: A total of 46 patients underwent single-component AUS revisions following primary AUS placement from January 1983 to January 2011 at our institute. Prior to 1996 all revision cases were performed with suture-tie connections and after that time we used QC for revisions.

The Effect of Anticoagulation on Bleeding-related Complications Following Ureteroscopy.

Objective: To analyze bleeding-related complications among patients on long-term anticoagulation (AC) undergoing ureteroscopy (URS). Current American Urological Association/International Consultation on Urological Diseases guidelines state that it is safe to continue AC in routine URS; however, these recommendations are based on small case series.

Patients And Methods: There were 4799 identified URS procedures performed at our institution between June 2009 and February 2016.

The Effect of Antiplatelet Agents on Bleeding-Related Complications After Ureteroscopy.

Introduction: The American Urological Association (AUA) guidelines state that continuing anticoagulation and antiplatelet agents in routine ureteroscopy (URS) is safe and without increased risk of complications. However, these recommendations are based on small case series; thus, we sought to analyze bleeding-related complications among patients on antiplatelet therapy (APT).

Materials And Methods: Overall, 4799 URS procedures performed at our institution between June 2009 and February 2016 were identified.

Surgeon fatigue: impact of case order on perioperative parameters and patient outcomes.

Purpose: We tested the hypothesis that surgeon fatigue results in worse outcomes for laparoscopic and robot-assisted laparoscopic prostatectomy, and percutaneous nephrolithotomy by comparing outcomes of sequentially scheduled procedures.

Materials And Methods: We identified days when 2 procedures of the same type were performed by the same surgeon, including 72 laparoscopic and 340 robot-assisted laparoscopic prostatectomies, and 110 percutaneous nephrolithotomies. Clinical data and outcomes were compared.

Isolation and characterization of CvIV4: a pain inducing α-scorpion toxin.

Background: Among scorpion species, the Buthidae produce the most deadly and painful venoms. However, little is known regarding the venom components that cause pain and their mechanism of action. Using a paw-licking assay (Mus musculus), this study compared the pain-inducing capabilities of venoms from two species of New World scorpion (Centruroides vittatus, C.
