AI Article Synopsis

  • The study used retrograde tracing and immunofluorescence to analyze neuron distribution and chemical coding in aorticoerenal (ARG) and testicular (TG) ganglia that supply the urinary bladder apex (UBA) in juvenile male pigs.
  • Fast Blue tracer was injected into the bladder to label neurons, and after three weeks, various neurochemicals like tyrosine hydroxylase and neuropeptide Y were investigated in the ganglia using confocal microscopy.
  • Findings showed a significant number of neurons projecting to the UBA, mainly in TG and predominantly noradrenergic, suggesting a complex neuro-endocrine role in regulating porcine urogenital function.

Article Abstract

Combined retrograde tracing and double-labelling immunofluorescence were used to investigate the distribution and chemical coding of neurons in aorticoerenal (ARG) and testicular (TG) ganglia supplying the urinary bladder apex (UBA) in the juvenile male pig (n=4, 12 kg. body weight). Retrograde fluorescent tracer Fast Blue (FB) was injected into the wall of the bladder apex under pentobarbital anesthesia. After three weeks all the pigs were deeply anesthetized and transcardially perfused with 4% buffered paraformaldehyde. TG and ARG were collected and processed for double-labelling immunofluorescence. The presence of tyrosine hydroxylase (TH) or dopamine beta-hydroxylase (DBH), neuropeptide Y (NPY), somatostatin (SOM), galanin (GAL), nitric oxide synthase (NOS) and vesicular acetylcholine transporter (VAChT) were investigated. The cryostat sections were examined with a Zeiss LSM 710 confocal microscope equipped with adequate filter blocks. The TG and ARG were found to contain many FB-positive neurons projecting to the UBA (UBA-PN). The UBA-PN were distributed in both TG and ARG. The majority were found in the left ganglia, mostly in TG. Immunohistochemistry disclosed that the vast majority of UBA-PN were noradrenergic (TH- and/or DBH-positive). Many noradrenergic neurons also contained immunoreactivity to NPY, SOM or GAL. Most of the UBA-PN were supplied with varicose VAChT-, or NOS- IR (immunoreactive) nerve fibres. This study has revealed a relatively large population of differently coded ARG and TG neurons projecting to the porcine urinary bladder. As judged from their neurochemical organization these nerve cells constitute an important element of the complex neuro-endocrine system involved in the regulation of the porcine urogenital organ function.

Purpose: Urinary cytokine changes may serve as biomarkers to assess treatment outcomes for interstitial cystitis/bladder pain syndrome (IC/BPS). This study analyzed the changes in urinary cytokines following various bladder therapies and explored their clinical significance in therapeutic mechanisms.

Methods: A total of 122 patients with IC/BPS treated with platelet-rich plasma (PRP), botulinum toxin-A (BoTN-A), hyaluronic acid (HA), or low-energy shock wave (LESW) were evaluated.

Department of Urology, Affiliated Yancheng Hospital, School of Medicine, Southeast University, Yancheng, Jiangsu, China.

Background: The relationship between serum total bilirubin (STB) concentrations and the risk of overactive bladder (OAB) remains uncertain. This study aims to explore the potential connection between STB and OAB.

Method: We utilized data from the National Health and Nutrition Examination Survey (NHANES) database for the years 2001-2020.

Objectives: To assess long-term outcomes (up to 10 cycles) of repeated intradetrusor botulinum toxin (BoNT) utilisation in multiple sclerosis (MS) and idiopathic overactive bladder (OAB).

Materials And Methods: This is a retrospective, international, multi-centre, observational cohort study of patients diagnosed with MS and neurogenic OAB and treated with intradetrusor BoNT between January 2005 and January 2020 (just prior to COVID-19 interruption). Dose, efficacy, duration of effect, International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB) and International Consultation on Incontinence Questionnaire Urinary Incontinence (ICIQ-UI) measures and complication rates were recorded.

Background: Pelvic organ prolapse (POP) occurs when one or more pelvic organs (uterus, bowel, bladder or top of the vagina) descend from their normal position and bulge into the vagina. Symptoms include pelvic discomfort, fullness, and changes in bladder or bowel function. Treatment ranges from conservative approaches to surgery, depending on symptom severity.

Objectives: To determine the health utility values (HUVs) of overactive bladder (OAB), defined as urinary urgency, usually accompanied by urinary daytime or nocturnal frequency, with or without urinary incontinence, among adults aged ≥65 years and to assess the HUV decrements (disutilities) of OAB according to its severity.

Methods: This cross-sectional Internet-based study was conducted between 2 and 9 November 2023, with quota sampling with equal probability for each sex and age group (age 65-74 years and ≥75 years). OAB was defined as an urgency score of ≥2 points and a total score of ≥3 points based on the Overactive Bladder Symptom Score.
