Article Abstract
Background: The status of heavy metals in children with lower urinary tract pathology that may harm the upper tract, e.g., neuropathic bladder and posterior urethral valve and its relationship with oxidative stress has not been adequately investigated. Therefore, the object of the current work was to evaluate the concentrations of copper, zinc, cadmium and lead and their relations with levels of catalase (CAT), malondialdehyde (MDA) and glutathione (GSH) in boys with neuropathic bladder and posterior urethral valve.
Methods: Thirty-six children with neuropathic bladder, 35 children with posterior urethral valve and 33 health controls were included in the study. In addition to routine laboratory tests, blood samples were collected from patients and controls to assess levels of Cu, Zn, Cd and Pb in addition to plasma concentrations of CAT, MDA and GSH.
Results: Significantly elevated levels of Cu, Pb, CAT, MDA and GSH and significantly lower concentration of blood Zn were found in the studied groups compared to the controls. In the posterior urethral valve group, blood level of Cu was positively correlated with GSH while a significantly negative relation was observed between blood Zn and CAT activity among the neuropathic bladder patients.
Conclusion: Neuropathic bladder and posterior urethral valve may lead to abnormalities in the blood levels of heavy metals (i.e. Cu, Pb and Zn) and markers of oxidative stress (CAT, MDA and GSH). Therefore, the levels of theses metal ions should be monitored during the treatment course of neuropathic bladder and posterior urethral valve patients to prevent or minimize long-term oxidative injury.

Urinary dysfunction caused by central nervous system or peripheral nerve disease represents a significant global medical and social problem. Neurologic abnormalities, including traumatic brain injury (TBI), stroke, Alzheimer's disease, and Parkinson's disease, have been identified as potential risk factors for neurogenic urinary tract dysfunction. The relationship between TBI and neurogenic lower urinary tract dysfunction (NLUTD) will be introduced in this article, with the mechanisms, clinical manifestations, diagnostic methods, and treatment strategies of NLUTD after TBI being evaluated as well, which provides a reference for the diagnosis and treatment.

Many patients with injuries to their central nervous system, especially those who have had a stroke or a spinal cord injury, have neurogenic voiding dysfunction. It happens when patients can't control their bladder voluntarily, which can make them feel urgency, experience leaks, or have trouble emptying their bladder. If not treated right away, it can cause infections, damage to the bladder, or even kidney problems over time.

Spinal cord injury (SCI) frequently leads to neurogenic lower urinary tract dysfunction, for which appropriate bladder management is essential. While clinical care relies on continuous low-pressure drainage in the acute phase, rat models commonly use twice-daily manual bladder expression-a method known to generate high intravesical pressures and retention. This study evaluated the impact of this standard practice on bladder tissue remodeling by comparing it to continuous drainage via high vesicostomy in a rat SCI model.

Individuals with spinal cord injury (SCI) and neurogenic bladder often rely on catheterization programs, which increase the risk of urinary tract infections (UTIs). Sodium-glucose cotransporter-2 inhibitors (SGLT2i), widely used in the management of diabetes mellitus (DM), chronic kidney disease (CKD), and congestive heart failure (CHF), promote urinary glucose excretion, potentially fostering an environment favorable to bacterial and fungal growth. This case describes a 53-year-old man with long-standing traumatic cervical SCI and a suprapubic catheter who presented with sepsis secondary to fungemia, in the context of SGLT2i use for DM management.

Background: The diagnosis of neurogenic lower urinary tract dysfunction (NLUTD) is complicated and often misdiagnosed by inexperienced physicians. Therefore, we used deep-learning algorithm models combined with video urodynamics to aid in the diagnosis of male NLUTD patients and construct an automated diagnosis and treatment process for such patients.
Methods: The urodynamic data from two cohorts of patients in our center with NLUTD were used: (1) A total of 284 male patients with NLUTD from 2009 to 2019 were used for model training and validation optimization; and (2) A cohort of 100 male patients with NLUTD from 2020 to 2021 were used for model testing.
