Low levels of serum testosterone in middle-aged men impact pathological features of prostate cancer.

Background: Serum testosterone deficiency increases with aging. Age is also a major risk factor for prostate cancer (PrCa) and PCa tumors are more frequently diagnosed among men >65 years old. We evaluated the relationship between preoperative serum testosterone and clinical/ pathological features of PrCa in middle-aged and elderly patients.

Does previous transurethral prostate surgery affect oncologic and continence outcomes after RARP?

We examined the effect of previous transurethral resection of the prostate (TURP) on multiple oncologic and continence outcomes after robotic-assisted radical prostatectomy (RARP). We performed a retrospective cohort study of a total of 2693 patients from 2007 to 2014 who underwent RARP. Patients were stratified into 49 patients who had previous TURP prior to RARP (group 1) and 2644 patients who had no TURP prior to RARP (group 2).

Can renal hemangiomas be diagnosed preoperatively?

Background: Renal hemangiomas are rare benign tumors seldom distinguished from malignant tumors preoperatively.

Objectives: To describe the Memorial Sloan-Kettering Cancer Center (MSKCC) experience with diagnosing and treating renal hemangiomas, and to explore possible clinical and radiologic features that can aid in diagnosing renal hemangiomas preoperatively.

Methods: Patients with renal hemangiomas treated at MSKCC were identified in our prospectively collected renal tumor database.

Use of a preoperative checklist reduces risk of penile prosthesis infection.

Purpose: Infection of a penile prosthesis is a devastating complication that necessitates the removal of all device components. Many aspects of preoperative and intraoperative infection prophylaxis practices have been examined but the specific relevant factors remain unknown. We determined whether use of a mandatory checklist of perioperative practices believed to reduce the risk of prosthesis infection would impact patient safety.

Monthly variations in urolithiasis presentations and their association with meteorologic factors in New York City.

Introduction: Nephrolithiasis in the United States has been on the rise during the past several decades. Temperature has been shown to directly correlate with increased stone disease. We examine the association between climactic factors and monthly urolithiasis presentation rates for 6 years at a single institution in New York City.

Lifestyle, environment, and male reproductive health.

A large number of environmental and lifestyle factors may negatively affect spermatogenesis and male fertility. This article enumerates the current state of knowledge regarding those that have been identified, and extrapolates the predicted magnitude of these effects over the next 20 years based on current societal trends. However, it is likely that additional factors have yet to be recognized.
