Comparative Neuroexcitation Patterns Using fNIRS in Women With Overactive Bladder.

Importance: Functional near-infrared spectroscopy (fNIRS) is a noninvasive technique used to quantify prefrontal cortex (PFC) neuroexcitation. The PFC is involved in the decision to void, and dysfunction in the region has been associated with overactive bladder (OAB). This study demonstrates neuroexcitation differences in the brain region associated with the decision to void (prefrontal cortex) using noninvasive fNIRS.

A stepwise approach for functional near infrared spectroscopy measurement during natural bladder filling.

Background: Functional near infrared spectroscopy (fNIRS) is a versatile, noninvasive, and inexpensive tool that can be used to measure oxyhemoglobin (OHb) changes in the cortical brain caused by increasing bladder sensation during filling in upright posture. This study's purpose is to provide a rigorous methodologic template that can be implemented for comparative studies of fNIRS in the diagnosis and management of lower urinary tract symptoms including overactive bladder (OAB) and other forms of lower urinary tract dysfunction.

Methods: Participants without any urologic conditions completed a validated oral hydration protocol facilitating and equilibrating natural bladder filling.

Oncologic outcomes following radical nephroureterectomy for upper tract urothelial carcinoma: a literature review.

Background And Objective: Radical nephroureterectomy (RNU) represents the gold standard treatment for non-metastatic upper tract urothelial cancer. We sought to provide a comprehensive review of reported oncologic outcomes of the RNU procedure and of factors that might impact these outcomes.

Methods: A non-systematic review of the literature was conducted by performing an electronic literature search using PubMed with "radical nephroureterectomy" and "oncologic outcomes" as free text search terms.

The use of low-intensity extracorporeal shockwave therapy in management of erectile dysfunction following prostate cancer treatment: a review of the current literature.

Background And Objective: Erectile dysfunction (ED) is a prevalent and impactful complication post definitive management of prostate cancer. The mechanism of ED is thought to be secondary to vascular and neural injury as well as corporal smooth muscle damage with resultant fibrosis. The use of penile rehabilitation in ED following treatment for prostate cancer has been studied.

A porcine bladder model of pre-clinical urodynamics demonstrates increased afferent nerve activity during filling.

Introduction And Objectives: Urodynamics are the accepted gold standard for the evaluation of multiple forms of voiding dysfunction. However, the tests are expensive, invasive, poorly reproducible, and often prone to artifacts. Therefore, there is a pressing need to develop next-generation urodynamics.
