Purpose Of Review: We reviewed the latest articles in patient-reported outcomes as it relates to genital gender-affirming surgery (GGAS) and provide a narrative summary of each article.

Recent Findings: The current landscape of patient-reported outcomes measures (PROMs) within GGAS largely consists of various ad hoc questionnaires. Within the last two years, one new PROM, validated within the transgender and gender-diverse (TGD) community, have been described.

Objective: Bladder neck contracture and vesicourethral anastomotic stenosis are difficult to manage endoscopically, and open repair is associated with high rates of incontinence. In recent years, there have been increasing reports of robotic-assisted bladder neck reconstruction in the literature. However, existing studies are small, heterogeneous case series.

Vesicoureteral reflux (VUR) is a medical condition where urine flows retrograde from the bladder superiorly, and has traditionally been considered a risk factor for kidney damage in children. However, over the past decade and a half, several randomized controlled trials have shown the risk of kidney damage in the presence of VUR is low, and any treatment for VUR does not change that risk. Here, we review the history of VUR as a pathologic condition, how the interpretation of that history led to possibly overestimating the danger, and how current findings should be seen in the context of that history.

Background: Sexual health is critical to overall health, yet sexual history taking is challenging. LGBTQ+ patients face additional barriers due to cis/heteronormativity from the medical system. We aimed to develop and pilot test a novel sexual history questionnaire called the Sexual Health Intake (SHI) form for patients of diverse genders and sexualities.

Objective: To compare clinically significant prostate cancer detection with TP-TBx utilizing software vs cognitive fusion. It is established that MRI prior to prostate biopsy improves detection of clinically significant cancer (csPCa, Grade Group ≥2). MRI/US fusion targeted biopsy via a transperineal approach (TP-TBx) is increasing in utilization due to the clean percutaneous approach that greatly reduces postbiopsy infection.

Background And Objective: There is insufficient evidence on the oncologic risks of testosterone therapy for men with prostate cancer managed with active surveillance. We carried out a retrospective study to assess the effect of testosterone therapy on oncologic outcomes for men on active surveillance for prostate cancer.

Methods: Surveillance, Epidemiology and End Results (SEER)-Medicare linked data were used to identify men diagnosed with prostate cancer from 2008 to 2017 who were managed with active surveillance and received testosterone ( = 167) or no testosterone ( = 6658) therapy.

Objective: To evaluate the incidence of gender-affirming phalloplasty and postoperative complications in a large population-based dataset.

Methods: Retrospective cohort study was done using the California Department of Health Care Access and Information datasets which include patient-level data from all licensed hospitals, emergency departments, and ambulatory surgery facilities in California. Adult patients 18 years or older undergoing gender-affirming phalloplasty in California from January 1, 2009 to December 31, 2019 were included.

Article Synopsis
  • This study compares same-day discharge robotic-assisted radical prostatectomy to traditional inpatient procedures, motivated by the need for inpatient beds during the COVID-19 pandemic.
  • It involved 392 surgeries across two medical centers, analyzing complications, healthcare costs, and patient satisfaction within 30 days post-surgery.
  • Findings indicated similar complication rates, a significant cost reduction of about $2106, and no notable difference in patient satisfaction, suggesting same-day discharge is a viable option for selected patients.

Objective: To determine surgical outcomes in a large of cohort men undergoing robotic-assisted posterior urethroplasty (RPU), which has been described in small series as a viable option.

Materials And Methods: We performed a retrospective review of all 105 men who underwent RPU from October 2014 to August 2022 at a single institution. We evaluated postoperative outcomes, including complications; surgical success defined as no need for reintervention; and incontinence requiring artificial urinary sphincter placement.

Since the US Food and Drug Administration first approved robotic surgery for clinical use in 2000, it has gained widespread adoption across multiple surgical domains. While pediatric surgery has had a relatively slower adoption rate, robotic surgery has nonetheless grown in this context. This work traces the historical and regulatory aspects of pediatric robotic surgery, showing how it incorporated an existing robotic surgical system developed for adults; situates the technology within ethical frameworks for analyzing surgical innovation; and advocates for combined surgeon self-regulation and institutional oversight.

Article Synopsis
  • The study aimed to analyze if measuring stricture length before surgery impacts the procedure choice, intraoperative measurements, and postoperative outcomes.
  • Data was collected from the CORRUS database, comparing patients with and without preoperative stricture measurements to evaluate various outcomes, and found no significant differences in complications or recovery.
  • Although preoperative measurements were common, they did not provide substantial benefits for the surgical management of ureteral stricture disease, with only stricture length predicting some postoperative complications.

Background: Expert consensus recommends treatment of magnetic resonance imaging (MRI)-visible prostate cancer (PCa). Outcomes of partial-gland ablation (PGA) for MRI-invisible PCa remain unknown.

Objective: To compare recurrence-free survival, adverse events, and health-related quality of life (HRQoL) outcomes following cryoablation of MRI-visible vs invisible PCa.

Introduction: Practice patterns around the use of urodynamic evaluation (UDS) for benign prostatic hyperplasia (BPH) surgery are largely undefined. As such, we investigated factors associated with the use of UDS for BPH.

Methods: We used American Board of Urology case log data from 2008 to 2020, to compare patient- and surgeon-sided factors associated with UDS utilization and BPH surgeries.

The European Association of Urology and American Urological Association offer differing recommendations on the prostate biopsy approach to use to minimize infection. Current level 1 evidence demonstrates no difference in infectious complications.

Introduction: Approximately one million prostate biopsies are performed annually in the USA, and most are performed using a transrectal approach under local anaesthesia. The risk of postbiopsy infection is increasing due to increasing antibiotic resistance of rectal flora. Single-centre studies suggest that a clean, percutaneous transperineal approach to prostate biopsy may have a lower risk of infection.

Count Me In (CMI) was launched in 2015 as a patient-driven research initiative aimed at accelerating the study of cancer genomics through direct participant engagement, electronic consent and open-access data sharing. It is an example of a large-scale direct-to-patient (DTP) research project which has since enrolled thousands of individuals. Within the broad scope of 'citizen science', DTP genomics research is defined here as a specific form of 'top-down' research endeavour developed and overseen by institutions within the traditional human subjects research context; in novel ways, it engages and recruits patients with defined diseases, consents them for medical information and biospecimens sharing, and stores and disseminates genomic information.
