Objectives: To explore the context in which older men navigate treatment for stress urinary incontinence (SUI) following prostate surgery by characterizing lived experience of men with symptomatic SUI.

Subjects/patients And Methods: Mixed method study using surveys and semistructured interviews to examine a cohort of men who underwent evaluation for treatment of postprostatectomy SUI.

Results: Thirty-six men were interviewed after consultation for SUI and 31 had complete quantitative clinical data.

Background: Male stress urinary incontinence (SUI) is a known complication following surgical intervention on the prostate, particularly following surgery for prostate cancer. Effective surgical treatments for SUI include artificial urinary sphincter (AUS) and male urethral sling. Prior data suggest that men may forego available treatment despite bothersome symptoms.

Background: Frailty is common among urology patients in general as well as among men seeking evaluation for stress urinary incontinence (SUI), with 6.1% of men undergoing artificial urinary sphincter placement considered frail. It is unclear if and how patient views on frailty and incontinence severity impact decision-making with regards to SUI treatment.

Objective: To investigate which treatment attributes matter to patients with stress urinary incontinence (SUI), why and how they matter, and the context in which patients consider treatment attributes. Nearly a quarter of older men have decisional regret following SUI treatment. Knowledge of what matters to patients when making SUI treatment decisions is necessary to improve goal-concordant care.

Alternative care sites (ACS) across the United States were widely underutilized during the coronavirus disease (COVID-19) outbreak, while the volume and severity of COVID-19 cases overwhelmed health systems across the United States. The challenges presented by the pandemic have shown the need to design surge capacity principles with consideration for demand that strains multiple response capabilities. We reviewed current policy and previous literature from past ACS as well as highlighted challenges from the COVID-19 pandemic, to make recommendations that can inform future surge capacity planning.

Background: Gaza has been under land, sea, and aerial blockade for more than 13 years, during which time Israel has continued its permit regime to control access for Palestinian patients from Gaza to health facilities in the West Bank (including East Jerusalem), Israel, and Jordan. Specific groups, such as patients with cancer, have a high need for permits owing to a lack of services in Gaza. The approval rate for patient permits to exit Gaza dropped from 94% in 2012 to 54% in 2017.

Objective: To validate the performance of a natural language processing (NLP) model in characterizing the quality of feedback provided to surgical trainees.

Design: Narrative surgical resident feedback transcripts were collected from a large academic institution and classified for quality by trained coders. 75% of classified transcripts were used to train a logistic regression NLP model and 25% were used for testing the model.

Background: Gaza has been under land, sea, and aerial closure for 13 years, during which time Palestinian patients from Gaza have been required to obtain Israeli-issued permits to access health facilities in the West Bank (including east Jerusalem), as well as in Israel and Jordan. Specific groups, like cancer patients, have a high need for permits due to lack of services in Gaza. The approval rate for patient permits to exit Gaza dropped from 94% in 2012 to 54% in 2017.

Objective: 1) To identify baseline characteristics of caregivers of school-aged children with spina bifida; 2) To identify independent predictors of caregiver burden in this population.

Materials And Methods: A survey was distributed via Facebook advertising to caregivers of patients with congenital genitourinary anomalies from May to September 2018. Eligible participants (n = 408) entailed English-speaking adults who are involved in the patient's care and attend ≥50% of their medical appointments.

Introduction: In 2017, UCSF established a formal Transitional Urology (TU) clinic co-run by pediatric and adult urology aimed at providing comprehensive urologic care for people progressing into adulthood with complex urologic histories.

Objective: We aim to describe baseline demographic and disease characteristics of this population, understand gaps in care, and gauge follow-through.

Study Design: We performed a retrospective chart review of all new patients in the TU clinic at UCSF from February 2017 through January 2019.

Cobamides, a uniquely diverse family of enzyme cofactors related to vitamin B, are produced exclusively by bacteria and archaea but used in all domains of life. While it is widely accepted that cobamide-dependent organisms require specific cobamides for their metabolism, the biochemical mechanisms that make cobamides functionally distinct are largely unknown. Here, we examine the effects of cobamide structural variation on a model cobamide-dependent enzyme, methylmalonyl coenzyme A (CoA) mutase (MCM).

Aims: To examine the impact of frailty on treatment outcomes for overactive bladder (OAB) in older adults starting pharmacotherapy, onabotulinumtoxinA, and sacral neuromodulation.

Methods: This is a prospective study of men and women age ≥60 years starting pharmacotherapy, onabotulinumtoxinA, or sacral neuromodulation. Subjects were administered questionnaires at baseline and again at 1- and 3-months.

Objective: To identify locations of recurrence after radical prostatectomy (RP) with prostate-specific antigen (PSA) <2 by Gallium-68 prostate-specific membrane antigen (PSMA)-11 Positron Emission Tomography (PET) imaging, and to determine whether standard nodal radiation fields would cover the location of prostate cancer recurrence.

Materials And Methods: We performed a retrospective review of patients with PSMA-PET imaging for biochemical recurrence following RP with PSA ≤2.0 ng/mL and assessed if the recurrent disease was within standard radiation target volumes.

Objective: To explore whether there is an association between nonwhite race and frailty among older adults presenting to an academic nononcologic urology practice.

Materials And Methods: This is a prospective study of individuals ages ≥65years presenting to a nononcologic urology practice between December 2015 and November 2016. All individuals had a Timed Up and Go Test (TUGT, where a slower TUGT time of ≥15 seconds is suggestive of frailty.

Objective: To understand the relationship between frailty, age, and recurrent urinary tract infections (rUTIs).

Materials And Methods: The Timed Up and Go Test (TUGT), a measure of frailty, was administered to all adults aged ≥65 presenting to an academic nononcologic urology practice from December 2015 to January 2018. TUGT was categorized as fast (≤10 seconds), intermediate (11-14 seconds) or slow (≥15 seconds).

Objective: To understand the relationship between age, frailty, and overactive bladder (OAB).

Materials And Methods: This is a prospective study of individuals age ≥65 years presenting to an academic urology practice between December 2015 and July 2016. All patients had a Timed Up and Go Test (TUGT), a parsimonious measure of frailty, on intake, and were thereby categorized as fast (≤10 seconds), intermediate (11-14 seconds), and slow (≥15 seconds).

Objective: To evaluate the prevalence of frailty, a known predictor of poor outcomes, among patients presenting to an academic nononcologic urology practice and to examine whether frailty differs among patients who did and did not undergo urologic surgery.

Methods: The Timed Up and Go Test (TUGT), a parsimonious measure of frailty, was administered to patients ages ≥65. The TUGT, demographic data, urologic diagnoses, and procedural history were abstracted from the medical record into a prospective database.
