Purpose: To evaluate the efficacy of specific antibiotic regimens in preventing infection following sacral neuromodulation.

Materials and methods: This is a retrospective cohort study utilizing the Premier Healthcare Database. Patients who underwent sacral neuromodulation placement between January 2016 and March 2020. The patients were grouped by those who received dual antibiotic therapy per 2019 AUA guidelines (Gram positive + broad Gram negative coverage), first- or second-generation cephalosporins or any other regimen. Comparison between groups was performed using Kruskal-Wallis and χ² tests for continuous and categorical variables, respectively. Inverse probability of treatment weighted (IPTW) analysis was used to estimate the average treatment effect of AUA guidelines regimens versus the use the first- or second-generation cephalosporins alone.

Results: The sample included 14 179 patients, with 2211 patients receiving prophylaxis that followed the AUA guideline recommendations. There was no significant difference in surgical site infection rates within 3 months (p = 0.28) or within 12 months (p = 0.53) between the groups. On IPTW, the probability of an infection at 3 months was lower with the AUA guideline regimens compared to those who received first- or second-generation cephalosporins alone, but this difference was not statistically significant (OR = 0.73, 95% CI: [0.43, 1.24]).

Conclusions: In the absence of allergies to cephalosporins or penicillin, first- or second-generation cephalosporins alone may be a sufficient preoperative antibiotic regimen for prevention of infection at the time of sacral neuromodulation.

Trial registration: Not applicable due to being a database study.

Aim: Current guidelines on surgical treatment of stress urinary incontinence (SUI) recommend an informed decision making process between the physicians and patients reviewing all available surgical options with and without mesh. However, there is a lack of synthesized clinical evidence on some of the comparisons that can feed into patient counseling processes. The aim of this study was to review the available studies comparing clinical outcomes of an autologous fascial sling (AFS) and a retropubic (RP) synthetic sling for women undergoing a primary surgery for SUI.

Methods: We conducted a literature search from 1990 to 2024 following international guidelines. We have included studies reporting on comparative outcomes of AFS and RP synthetic sling surgeries as a primary procedure.

Results: Three randomized studies were included with follow-up durations ranging from 24 months to 10 years. The mean percentage change in symptom scores ranged from 27.7% to 44.9%, with no significant difference between the two sling types. There was no difference between groups with regard to objective cure rates, subjective cure rates and length of hospital stay between AFS and RP slings. AFS surgeries had longer operative times. There were concerns about bias, particularly related to allocation, blinding, and missing outcome data.

Conclusion: Overall, both types of slings had similar cure rates but AFSs were associated with longer operative times. The study highlights the need for more research on the comparative effectiveness of AFS and synthetic slings for SUI surgery to guide decision-making for SUI surgical treatments.

Introduction: One of the main causes of a neurogenic bladder is spinal cord injury (SCI),(SCI), which induces little or no bladder reflex activity. Because of this alteration, there is an increased risk of developing urinary tract infections and kidney damage. Gonadotropin-releasing hormone (GnRH) treatment has been shown to improve micturition in a rat model of SCI.

Aim: The present study was aimed at determining whether GnRH administration is capable to reduce bladder and kidney damage in rats with SCI.

Methods: Ovariectomized female Wistar rats were divided into three groups: sham, SCI with saline solution (SCI), and SCI treated with GnRH (SCI+GnRH) for 6 weeks. SCI was induced by compression at the T10 spinal level. At the end of the experiment, bladders and kidneys were processed for morphological and immunofluorescence analysis. For morphometric analysis, the thickness of the urothelium and the muscular layer of the bladder was measured, as well as the intensity of staining related to collagen in the kidney.

Results: At the end of the experiment, all animals in the sham group showed normal urination (100%), in contrast, the percentage of untreated injured rats (SCI) that did not require manual stimulation for micturition was 19%, while the treated group (SCI+GnRH) was 68%. A significative increase in bladder weight, urothelial and muscle thickness, and collagen-related coloration in the kidney was observed in SCI when compared to sham rats.

Conclusion: GnRH administration decreased damage to the urinary bladder and kidneys after SCI in rats. These results suggest that this hormone could be a potential preventive treatment for SCI patients at risk of neurogenic bladder and kidney damage.

Trial registration: Not applicable.

Introduction: Recovery of lower urinary tract (LUT) and lower gastrointestinal tract (LGIT) is a high priority for people with lived experience following spinal cord injury (SCI). A universally accepted validated patient-reported outcome (PRO) measure of the individual sensory and motor components of LGIT and LUT function, which allows tracking of recovery is lacking. To address this literature gap, the SCI Bladder and Bowel Control Questionnaire (SCI-BBC-Q) was developed.

Methods: The SCI-BBC-Q was developed as a direct assessment of the micturition and defecation experiences of an individual with SCI with possible neurogenic LUT and LGIT dysfunction. The SCI-BBC-Q development process consisted of two phases, measure development and evaluation. Measure development was guided by a conceptual framework, review of existing instruments and literature, and an iterative process of item incorporation, review, feedback, and consensus revision. Evaluation included cognitive interviewing, and assessments of feasibility, reliability, and content validity.

Results: The final 6-item SCI-BBC-Q is a PRO, which assesses motor and sensory function related to micturition and defecation, requiring ~5 min to complete. Assessments of clarity of the instrument components with regard to understanding of what is being asked in the questionnaire, feasibility of administration, reliability, internal consistency, and agreement with proxy measures have demonstrated that the SCI-BBC-Q provides consistent, stable, and reproducible data. Significant correlations were found between SCI-BBC-Q scores and the anorectal motor and sensory components of the International Standards for the Neurological Classification of SCI.

Conclusion: The SCI-BBC-Q is a practical and reliable method for baseline and ongoing evaluation of patients with neurogenic LUT and LGIT dysfunction, especially in the acute and subacute period when function is changing due to neurological plasticity. It is also appropriate for use in monitoring response to treatments related to neurological recovery.

Objective: Young adults with spina bifida (and other congenital neurologic diseases) have their own aspirations that may include education, employment, relationships and having children. As they move from pediatric to adult care, they must eventually transition to an adult healthcare team. The objective of this paper is to review the challenges and controversies in the transitional and adult care of people with congenital neurourological diseases.

Methods: The Research Group convened a meeting of its members and invited guests to better understand the healthcare challenges faced by these patients as they become adults. The group examined potential research opportunities focused on people with these diagnoses and themes related to their healthcare.

Results: Trust and clear communication are essential for effective patient transition. Ideally parents are involved in the transition to help reinforce independent self-care and responsibility. Adolescents require education about sexual health and independence, which may not be part of the core skillset of a urologist. The healthcare team must promote self-management and autonomy as early as practical. One of the major limitations is that adult care lacks the coordination of pediatric care, and patients may not have a "medical home." Multidisciplinary clinics are ideal but face logistical barriers in adult medicine. Additional barriers include limited physicians with the required specialized training. In the adult system, financial constraints are a key challenge for patients and providers.

Conclusion: Collaboration, supported by institutions and new research, is vital for improving the neurourological care of young adults with complex diseases.

Trial registration: This study reports on the proceedings of a meeting, and therefore clinical trial registration was not necessary.

Aims: This study aimed to determine the efficacy and safety of iltamiocel investigational autologous muscle cell therapy in females with stress urinary incontinence (SUI).

Methods: Adult females were randomized 2:1 to iltamiocel (150 × 10⁶ cells) or placebo and stratified by severity and prior SUI surgery. The primary objective was efficacy based on the frequency of stress incontinence episodes (SIE) recorded in a 3-day diary at 12 months posttreatment. After 12 months, placebo participants could elect to receive open-label iltamiocel. Efficacy and safety analyses were performed using all patients as treated populations.

Results: The study enrolled 311 patients, 297 were randomized to either iltamiocel (n = 199) or placebo (n = 98). Of the 295 participants that completed 12 months blinded follow-up, the proportion achieving the primary endpoint of ≥ 50% SIE reduction was not statistically different between treatment groups (52% vs. 53.6%; p = 0.798). A significantly greater proportion of iltamiocel participants in the prior SUI surgery stratum group achieved ≥ 75% SIE reduction compared with placebo, (40% vs. 16%; p = 0.037). Treatment response was maintained at 24 months in 78.4% and 64.9% of iltamiocel participants who achieved ≥ 50% and ≥ 75% SIE reduction, respectively, at Month 12. Adverse events related to the treatment were reported in 19 (9.5%) iltamiocel participants and 6 (6.1%) placebo participants.

Conclusion: The study did not meet its primary endpoint however, iltamiocel cell therapy is safe and may be ideally suited to female patients who have undergone prior surgery for SUI. Additional study in this group of patients with high unmet medical needs is warranted.

Aims: Compensatory coping, or maladaptive alterations in behavior with the intention of preventing or managing symptoms, is increasingly being explored as a key factor in how people respond to bladder conditions. Preliminary investigations have identified relations between coping behaviors and psychological distress in urologic conditions, including interstitial cystitis/bladder pain syndrome (IC/BPS). However, previous explorations of coping have not accounted for heterogeneity in coping behaviors or addressed the likelihood that some coping behaviors may be more adaptive than others. This study sought to examine how two specific types of coping behaviors, primary control coping and disengaged coping, are related to distress and symptoms in IC/BPS, and to explore the potential role of pain phenotype in this relationship.

Materials and methods: A secondary data analysis was conducted with a large community data set (N = 677 women with IC/BPS) and employed descriptive and inferential statistics to characterize coping patterns and explore novel predictors of distress.

Results: Results indicated that almost all participants engaged in at least one compensatory coping behavior within the last week. Both types of coping behaviors correlated with psychological symptoms, and when controlling for relevant clinical variables (i.e., age and severity of urinary symptoms), disengaged coping behaviors were significantly associated with psychological distress. Further, the addition of pain phenotype to multiple regression models resulted in a more effective predictive model when considering the relation between coping behaviors and depression.

Conclusions: By investigating more deeply the relationship between coping and distress, understanding of potential risk factors and mechanisms is increased, offering valuable insights for intervention strategies for IC/BPS patients.
