Continuous monitoring of bladder activity during normal daily activities would improve clinical diagnostics and understanding of the mechanisms underlying bladder function, or help validate how differing neuromodulation strategies affect the bladder. This work describes a urological monitor of conscious activity (UroMOCA). The UroMOCA included a pressure sensor, urine impedance-sensing electrodes, and wireless battery recharge and data transmission circuitry. Components were assembled on a circuit board and encapsulated with an epoxy/silicone molded package that allowed Pt-Ir electrode feedthrough for urine contact...

Proteus mirabilis , a prevalent urinary tract pathogen and formidable biofilm producer, especially in Catheter-Associated Urinary Tract Infection, has seen a worrying rise in multidrug-resistant (MDR) strains. This upsurge calls for innovative approaches in infection control, beyond traditional antibiotics. Our research introduces bacteriophage (phage) therapy as a novel non-antibiotic strategy to combat these drug-resistant infections. We isolated P2-71, a lytic phage derived from canine feces, demonstrating potent activity against MDR P...

BACKGROUND: With ever increasing rates of emergency caesarean deliveries (CD),incorporating the ERAS protocol might provide a perfect window of opportunity to increase maternal comfort during the postsurgical period, but also improve outcomes and facilitate optimal return of physiological function. OBJECTIVE: To determine whether an ERAS pathway at emergency caesarean birth would permit a reduction in postoperative length of stay and improve postoperative patient satisfaction...

Microplastics (MPs) are found in all environments, within the human food chain, and have been recently detected in several human tissues. The objective herein was to undertake an analysis of MP contamination in human urine samples, from healthy individuals and participants with endometriosis, with respect to their presence, levels, and the characteristics of any particles identified. A total of 38 human urine samples and 15 procedural blanks were analysed. MPs were characterised using μFTIR spectroscopy (size limitation of 5 μm) and SEM-EDX...

The overactive bladder is a condition characterized by a sudden urge to urinate, even with small volumes of urine present in the bladder. The current treatments available for this pathology consist on conservative approaches and the continuous administration of drugs, which when made by conventional methods has limitations related to the first pass metabolism, bioavailability, severe side effects, and low patient adherence to treatments, ultimately leading to low effectiveness. Within this context, the present work proposes the design, manufacture, and characterization of an intravesical implant for the treatment of overactive bladder pathology, using EVA copolymer as a matrix and oxybutynin as a drug...

BACKGROUND: Foley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T-Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterization by a multifactorial approach. The general purpose of this study is to determine the effectiveness, comfort, and experience of the patient catheterized with T-Control® compared with patients with a conventional Foley catheter...

Pelvic fractures sometimes lead to injuries of the urinary bladder, which commonly present as gross hematuria, dysuria and lower abdominal pain. As a type of urinary stone, bladder stones are usually secondary to lower urinary tract obstruction, such as benign prostatic hyperplasia, urethral stricture, and neurogenic bladder. The present case report examines an unusual case of a delayed pubic fracture penetrating the bladder, which caused a secondary bladder stone. A 53-year-old man was first hospitalized at The Second Hospital of Jiaxing (Jiaxing, China) in January 2020 because of trauma-induced bleeding in the scalp and abdominal pain...

PURPOSE: Convective water vapor thermal therapy or "Rezum™" treatment for lower urinary tract symptoms in men with benign prostate hypertrophy require postoperative catheterization to avoid acute urinary retention. Unsuccessful catheter removal is still unpredictable. We, therefore, aimed to identify the risk factors of failed initial trial without catheter (TWOC) after Rezum™ therapy inside a large cohort of patients. METHODS: A retrospective study was conducted on patients who underwent Rezum™ therapy by three referent urologists across two academic hospitals between January 2022 and January 2023...

Introduction Transurethral resection of the prostate (TURP) is the standard surgical procedure for obstructive symptoms of the lower urinary tract when medical management fails. Progression in TURP procedures has led to reduced catheterization time following transurethral prostatic resection. This study describes the methods and results of TURP performed in the day surgery setting. Materials and methods This retrospective study was performed at a day surgical hospital serving a patient population of more than 200,000 people...

OBJECTIVES: We aimed to identify the prevalence, bacterial isolates, antimicrobial susceptibility profile, and factors associated with asymptomatic bacteriuria (ASB) in patients with type 2 diabetes mellitus (T2DM) in rural southwestern Nigeria. METHODS: We performed a hospital-based cross-sectional study of patients with T2DM and ASB. Demographic and clinical data were collected using questionnaires. Urine samples were cultured using standard laboratory procedures, and bacterial colonies were isolated and antimicrobial sensitivity was performed using the disc diffusion technique...

BACKGROUND: Antimicrobial resistance among Enterobacterales continues to be a growing problem, particularly in those with urinary infections. Previous studies have demonstrated safety and efficacy with the use of single-dose aminoglycosides in uncomplicated cystitis. However, data in complicated infections are limited. Single-dose aminoglycosides may provide a convenient alternative for those with or at risk for resistant pathogens causing complicated urinary infections, especially when oral options are unavailable due to resistance, allergy, intolerance, or interactions with other medications...

Catheter-associated urinary tract infection (CAUTI) is defined as a urinary tract infection associated with catheter placement for more than two consecutive days. Hence, antibiotic resistance in the context of CAUTIs represents a substantial challenge. The aim of this study was to present the characteristics of patients with CAUTI and the susceptibility pattern of CAUTI bacteria in the national reference hospital of the Sumatra region of Indonesia. A cross-sectional study was conducted at H. Adam Malik General Hospital, Medan, Indonesia, from 2020 to 2021, using a total sampling...

BACKGROUND: Antimicrobial stewardship programmes are needed in long-term care facilities (LTCFs) to tackle antimicrobial resistance. We aimed to identify factors associated with antibiotic use in LTCFs. Such information would be useful to guide antimicrobial stewardship programmes. METHOD: We conducted a systematic review of studies retrieved from PubMed, Cochrane Library, Embase, APA PsycArticles, APA PsycINFO, APA PsycTherapy, ScienceDirect and Web of Science...

BACKGROUND: In urology, ureteral stents are used to treat obstructive diseases. Hematuria (54%), fever, discomfort, and lower urinary system symptoms are the predominant symptoms related to ureteral stent. AIM: This article links stent symptoms to double-j width and length, as well as patient's height, weight, and body mass index (BMI). Ureteric Stent Symptoms Questionnaire (USSQ) was used to measure ureteral stent symptoms at 1st and 4th week of stent in situ as well as the 4th week after pigtail removal...

Heat stress (HS) is a global issue that decreases farm profits and compromises animal welfare. To distinguish between the direct and indirect effects of HS, 16 multiparous Holstein cows approximately 100 d in milk were assigned to one of 2 treatments: pair fed to match HS cow intake, housed in thermoneutral conditions (PFTN, n = 8) or cyclical HS (n = 8). All cows were subjected to 2 experimental periods. P1 consisted of a 4 d thermoneutral period with ad libitum intake. During P2, the HS cows were housed in cyclical HS conditions with a temperature humidity index (THI) ranging from 76 to 80 and the PFTN cows were exposed to a constant THI of 64 for 4 d...

The standard treatment for non-muscle invasive bladder cancer (NMIBC) is transurethral resection of bladder tumor (TURBT). However, this procedure may miss small lesions or incompletely remove them, resulting in cancer recurrence or progression. As a result, intravesical instillation of chemotherapy or immunotherapy drugs is often used as an adjunctive treatment after TURBT to prevent cancer recurrence. In the traditional method, drugs are instilled into the patient's bladder through a urinary catheter under sterile conditions...

This study focuses on enhancing interventional medical devices, specifically catheters, using a novel composite material. Challenges like corrosion and contamination in vivo, often caused by body fluids' pH, bacteria, and proteins, lead to mechanical damage, bacterial colonization, and biofilm formation on devices like catheters. The objective of this study was to prepare a versatile composite (HFs) by designing polyurethanes (HPU) with an ionic chain extender (HIID) and blending them with amphiphilic nanofibrillated cellulose (Am-CNF)...

Cultures from urinary catheters are often ordered without indication, leading to possible misdiagnosis of catheter-associated urinary tract infections (CAUTI), increasing antimicrobial use, and C difficile . We implemented a diagnostic stewardship intervention for urine cultures from catheters in a community hospital that led to a reduction in cultures and CAUTIs.

Bacteriuria in paediatric oncology patients have not been well studied. This retrospective study analysed clinical features, distribution and antimicrobial susceptibility of bacterial pathogens cultured from urine in paediatric oncology patients over a 4-year period (2019-2022). A total of 143 episodes of bacteriuria were documented in 74 patients. Neutropenia was present in 17.5% (25/143), symptoms in 25.9% (37/143) and urinary catheter in 7.0% (10/143) episodes. Symptomatic bacteriuria episodes were statistically significantly more frequent in patients with neutropenia ( p = 0...

Robot-assisted radical prostatectomy (RARP) is difficult in patients with benign prostatic hyperplasia (BPH), a condition causing frequent urination, because of the large prostate volume and particularly true when BPH is accompanied by an enlarged middle lobe. To overcome this difficulty, some surgeons elevate the middle lobe with a third arm or tow the urethral catheter to the edge to identify the resection line. Herein, we describe a method for lifting a prostate with an enlarged middle lobe, which was successfully applied in a patient with prostate cancer and BPH...
