Background: While nearly 50% of adult women report at least one episode of urinary incontinence (UI), most never receive treatment.

Objective: To better integrate primary and specialty UI care, we conducted (i) an environmental scan to assess the availability of key pathway resources in primary care, (ii) interviews with primary care providers to understand barriers to care, and (iii) a pilot UI care pathway intervention.

Methods: Environmental scan: Clinic managers from all primary care clinics within a Midwestern healthcare system were invited to participate in an interview covering the availability of clinic resources.

Introduction: Staged sacral neuromodulation (SNM) testing has been shown to have a high rate of progression to permanent implantation for the management of voiding dysfunction. Stage 1 lead placement (SNM-I) can be performed under monitored anesthesia care (MAC) or general anesthesia (GA). MAC allows for interpretation of sensory and motor responses to optimize lead placement while GA only permits for motor assessment.

Importance: Although behavioral modifications, medications, and other interventions can improve urinary incontinence (UI), many women never receive them.

Objectives: To better characterize UI treatment patterns in primary care, we examined prescriptions and referrals to pelvic floor physical therapy (PFPT) and specialist physicians within a large Midwestern academic health system.

Study Design: Electronic health records were queried to identify a cohort of adult female patients receiving a new UI diagnosis during outpatient primary care visits from 2016 to 2020.

Introduction: Urinary Tract Infection (UTI) has been cited as the primary cause of morbidity in patients with history of spinal cord injury (SCI). Despite the significance of recurrent UTI (rUTI) in this population, the causative physiologic and patient characteristics are not well described. We sought to assess associations between demographic, clinical and urodynamic variables and rUTI.

We show that heart rate enabled wearable devices can be used to measure respiratory rate. Respiration modulates the heart rate creating excess power in the heart rate variability at a frequency equal to the respiratory rate, a phenomenon known as respiratory sinus arrhythmia. We isolate this component from the power spectral density of the heart beat interval time series, and show that the respiratory rate thus estimated is in good agreement with a validation dataset acquired from sleep studies (root mean squared error = 0.

Purpose: A ≥50% subjective improvement in urinary symptoms during sacral neuromodulation testing (SNM-I) is currently used as the indication for progression to second-stage implantation (SNM-II). While most patients will have successful SNM-I and proceed to SNM-II, deterioration in efficacy over time has been reported. It remains unclear if the durability of efficacy is related to the initial symptom reduction.

Aims: To evaluate the therapeutic effects of intradetrusor onabotulinum toxin A (BTX) injections in patients with adult neurogenic lower urinary tract dysfunction (ANLUTD) and medically refractory poorly compliant bladders.

Methods: We retrospectively evaluated patients with urodynamic studies (UDS)-proven, medically refractory impaired bladder compliance (≤20 mL/cm H O) secondary to spinal myelopathy treated with 300 units of BTX cystoscopically injected into the detrusor muscle. Objective improvement in compliance was defined as an increase ≥5 mL/cm H O on repeat urodynamics.

Inference of active regulatory mechanisms underlying specific molecular and environmental perturbations is essential for understanding cellular response. The success of inference algorithms relies on the quality and coverage of the underlying network of regulator-gene interactions. Several commercial platforms provide large and manually curated regulatory networks and functionality to perform inference on these networks.

Introduction: Classic surgical teaching advocates for closure of the mesenteric defect (MD) after bowel anastomosis but the necessity is controversial. We sought to evaluate the necessity of MD closure at the time of harvest of ileum for genitourinary reconstructive surgery (GURS) by analyzing the incidence of early and late gastrointestinal adverse events (GIAE) in patients with and without MD closure.

Materials And Methods: A retrospective review was conducted on patients undergoing urologic reconstruction with ileum to identify incidence of ileus, small bowel obstruction (SBO), gastrointestinal (GI) fistula and stoma complications.

Objective: With the goal of better defining the types of bladder dysfunction observed in this population, we present the chief urologic complaints, results of urodynamic studies, and treatments of patients with dysautonomia-related urinary symptoms.

Methods: All patients with dysautonomia referred to our neurourology clinic between 2005 and 2015 for management of lower urinary tract dysfunction were retrospectively reviewed. Each patient's chief urologic complaint was recorded and used to initially characterize the bladder storage or voiding symptoms.

Introduction: We instituted a ketamine-predominant analgesic regimen in the peri- and postoperative periods to limit the effects of narcotic analgesia on bowel function in patients undergoing radical cystectomy. The primary end points of interest were time to return of bowel function, time to discharge, and efficacy of the analgesic regimen.

Methods: We performed a retrospective chart review of patients undergoing robotic-assisted laparoscopic cystectomy (RARC) with urinary diversion by a single surgeon at our institution from January 1, 2011 to June 30, 2012.

The blockade of muscarinic receptors in the management of overactive bladder (OAB) symptoms provides beneficial as well as adverse effects. The cognitive changes observed are caused by the drugs' ability to cross the blood-brain barrier and bind to muscarinic receptors within the central nervous system (CNS). To date, while not specifically testing for CNS side effects, most of the controlled efficacy trials of multiple OAB medications have not shown significant adverse effects on cognitive function.
