Background: Urinary tract infections (UTIs) and the antibiotic resistance of pathogenic bacteria pose severe threats to public health in the current healthcare environment.
Objective: The purpose of this study was to assess the frequency distribution of bacterial pathogens causing UTIs as well as the characteristics of antibiotic susceptibility and resistance.
Methods: The retrospective study was conducted on 32,391 samples of midstream urine culture from January 1, 2020, to December 31, 2022, in Jiaxing. Bacteria were cultivated on blood agar and identified using MALDI-TOF, and their susceptibility to different antibiotics was assessed using the Kirby-Bauer disk diffusion method and drug sensitivity reaction cards. The SPSS 22 software was used for data analysis. Bivariate logistic regression was used to analyze the risk factors for multidrug resistance.
Results: The total number of positive growth samples was 5378 (16.6%), including 3206 females (59.6%) and 2172 males (40.4%). The four most common urinary pathogens were (39.2%), (12.4%), (7.6%), and (7.6%). As far as antibiotic resistance was concerned, had a greater than 50% resistance rate to ampicillin (76.1%), ciprofloxacin (58.6%), and levofloxacin (51.2%). The multidrug resistance rate was high (41.8%). Low levels of resistance were seen to ertapenem (0.1%), imipenem (0.7%), meropenem (0.7%), piperacillin/tazobactam (0.7%), and nitrofurantoin (1.8%). was highly sensitive to ertapenem (100%). The resistance rates to nitrofurantoin, ceftriaxone, and ciprofloxacin were 37.4%, 37.1%, and 35.1%, respectively. Up to 41% of strains and 26% of strains produced extended-spectrum lactamases (ESBL). Two species of enterococci were highly sensitive to tigecycline and linezolid (100%), and a small number of norvancomycin-resistant strains (0.2%/two strains) were found.
Conclusion: and were the most common urinary pathogens in this study. The isolated pathogens showed different sensitivity patterns. Antibiotics should be selected reasonably according to the sensitivity mode of pathogenic bacteria to effectively treat and prevent urinary tract infections.

A spinal cord injury (SCI) leads to neurogenic lower urinary tract dysfunction (NLUTD), which, if left untreated, can result not only in urinary incontinence and an increased risk of urinary tract infections and kidney dysfunction but may also pose a vital threat to people with SCI. Comprehensive neurourological assessments, including patient history and combined video urodynamics, are essential to accurately classify dysfunction and establish therapeutic strategies. Treatment options include, among others, medications for detrusor regulation, intermittent catheterization, and, if necessary, surgical interventions from intradetrusor botulinum toxin A injections to sacral deafferentation.

Objectives: To evaluate possible predictors of elevated postvoid residual volume (PVR) following onabotulinumtoxinA administration in patients with idiopathic overactive bladder (OAB), a condition that may include urinary urgency, frequency, and nocturia, without any identifiable cause or underlying neurological or metabolic condition.
Methods: Adults who had been treated with 100-200 U onabotulinumtoxinA for OAB and had previous failure of other OAB treatments were identified by retrospective review of medical chart data from three urology clinics in the United States treating patients with a variety of urological conditions. A total of 211 patients were allocated to cohorts based on posttreatment PVR < 200 mL (n = 173) and ≥ 200 mL (n = 38).

Background: Spinal tuberculosis is a common cause of spinal deformity and neurological dysfunction, with surgical treatment being crucial in severe cases. This study evaluates the efficacy and safety of combined anterior and posterior surgery with autologous tricortical iliac bone and rib grafting for treating spinal tuberculosis.
Methods: We included 61 patients with thoracic tuberculosis, who underwent a surgical procedure involving initial posterior correction, followed by anterior debridement and reconstruction with autologous tricortical iliac bone and rib grafts.

Annular pancreas is a rare congenital anatomical anomaly, in which the pancreatic parenchyma surrounds the descending duodenum. Generally, annular pancreas is diagnosed on the basis of symptoms associated with complications of peptic ulcer, pancreatitis, cholelithiasis, and rarely, malignant tumors. Herein, we report an 84-year-old man for whom, during hospitalization for a urinary tract infection, pancreatic cystic lesions and an annular pancreas were noted incidentally on computed tomography.
