Urinary bladder

BACKGROUND: Anticholinergic burden is associated with adverse events in the older adults. However, there is a lack of evidence regarding its effect on urinary independence in stroke patients. AIM: This study examined the association between increased anticholinergic burden during hospitalization and urinary independence in post-stroke patients undergoing rehabilitation. METHOD: This observational cross-sectional study included stroke patients admitted to a post-acute rehabilitation hospital between 2020 and 2022 who were not independently urinating...

BACKGROUND: Overactive bladder (OAB) affects one in six adults in Europe and the United States and impairs the quality of life of millions of individuals worldwide. When conservative management fails, third-line treatments including tibial neuromodulation (TNM) is often pursued. TNM has traditionally been accomplished percutaneously in clinic. OBJECTIVE: A minimally invasive implantable device activated by a battery-operated external wearable unit has been developed for the treatment of urgency urinary incontinence (UUI), mitigating the burden of frequent clinic visits and more invasive therapies that are currently commercially available...

OBJECTIVES: This study evaluated patients with occult spinal dysraphism who underwent spinal cord untethering. METHODS: Twenty-four patients who visited us between 1983 and 2000 were followed-up for a mean duration of 31 years. We studied their lower urinary tract function, skin stigmata, fertility, and work participation. RESULTS: Questionnaires sent in 2022 revealed that 5 patients had normal voiding (Group A) and 19 patients had abnormal voiding (Group B)...

Urothelium forms a distensible yet impermeable barrier, senses and transduces stimuli, and defends the urinary tract from mechanical, chemical and bacterial injuries. Biochemical and genetic labeling studies support the existence of one or more progenitor populations with the capacity to rapidly regenerate the urothelium following injury, but slow turnover, a low mitotic index, and inconsistent methodologies obscure progenitor identity. The progenitor properties of basal Keratin 5 urothelial cells (K5-UC) have been previously investigated, but those studies focused on embryonic or adult bladder urothelium...

OBJECTIVES: The objective of this study is to investigate the association between major adverse cardiac events (MACE) and clinical factors of patients undergoing radical cystectomy (RC) for bladder cancer. MATERIALS AND METHODS: A retrospective analysis using the 2015-2020 National Surgical Quality Improvement Program database was performed on patients who underwent RC for bladder cancer. MACE was defined as any report of cerebrovascular accident, myocardial infarction, or thromboembolic events (pulmonary embolism or deep vein thrombosis)...

BACKGROUND: Racial disparities in oncological outcomes resulting from differences in social determinants of health (SDOH) and tumour biology are well described in prostate cancer (PCa) but similar inequities exist in bladder (BCa) and renal cancers (RCCs). Precision medicine (PM) aims to provide personalized treatment based on individual patient characteristics and has the potential to reduce these inequities in GU cancers. OBJECTIVE: This article aims to review the current evidence outlining racial disparities in GU cancers and explore studies demonstrating improved oncological outcomes when PM is applied to racially diverse patient populations...

The prevalence of double primary prostate and bladder cancer is not uncommon. Though both share a common pathway of malignant transformation, they bear to differ in the case of 2-[18 F]FDG PET/CT and [68 Ga]Ga-PSMA uptake. We present a case of double primary cancer involving the bladder and prostate, where the prostatic primary showed intense [68 Ga]Ga-PSMA uptake with non-avid skeletal and pulmonary metastases, which showed intense 2-[18 F]FDG uptake, thus showing discordance due to different clonal origins...

AIMS: We hypothesise that PTNS is a safe and effective treatment for OAB. Overactive bladder (OAB) is estimated to affect 11.8% of women worldwide, causing diminished quality of life. Lifestyle modifications, muscarinic receptor antagonist and beta-adrenoreceptor agonist remain the mainstay of treatment but are limited by their efficacy and adverse effects. Access to third-line therapies of intravesical botulinum toxin type A or sacral neuromodulation is limited by their invasive nature...

Overactive bladder (OAB) and detrusor underactivity (DUA) are representative voiding dysfunctions with a chronic nature and limited treatment modalities, and are ideal targets for stem cell therapy. In the present study, we investigated the therapeutic efficacy of human mesenchymal stem cells (MSCs) with a high antioxidant capacity generated by the Primed Fresh OCT4 (PFO) procedure in chronic bladder ischemia (CBI)-induced OAB and DUA rat models. Sixteen-week-old male Sprague-Dawley rats were divided into three groups (sham, OAB or DUA, and stem cell groups; n=10, respectively)...

Modulation or stimulation of the nerves supplying the lower urinary tract is a possible treatment option for dysfunction of the lower urinary tract, pelvic floor and rectum if conservative or minimally invasive treatment approaches fail. This overview shows the possibilities and limitations of sacral neuromodulation, sacral deafferentation with sacral anterior root stimulation and conus deafferentation.Sacral neuromodulation (SNM) is a procedure for the treatment of refractory pelvic floor dysfunction of various origins (idiopathic, neurogenic or post-operative), such as overactive bladder, non-obstructive retention and faecal incontinence...

INTRODUCTION: Gastric outlet obstruction presents with a range of symptoms which include abdominal pain, early satiety, weight loss and vomiting caused obstruction secondary to tumors from outside the gastrointestinal tract or due to motility disorders. Bladder cancer is rarely associated with Gastric outlet obstruction. It usually presents with painless hematuria and urinary symptoms. Squamous cell carcinoma is a subtype of bladder malignancies that tends to present at a later stage and is associated with poorer prognosis in terms of metastasis and survival...

BACKGROUND: Peritoneal metastases (PM) have been reported in approximately 1% of patients with metastatic Renal Cell Carcinoma (mRCC). Outcome data are limited due to the rarity of this metastatic site. Therefore, the aim of our study is to describe renal cell carcinoma (RCC) patients with PM treated as per clinical practice. MATERIALS AND METHODS: Baseline characteristics and outcome data of patients with PM from RCC were retrospectively collected from 18 Italian oncological referral centers adhering to the Meet-Uro group, from January 2016 to January 2023...

Extracorporeal shock wave lithotripsy (ESWL) is a safe and efficient treatment option for urinary stone disease. The overall stone-free rate (SFR) varies significantly. This study aimed to assess the influence of stone size, location, stone density, and skin-to-stone distance (SSD), on the outcome of ESWL. We assessed whether pre-treatment non-contrast-enhanced CT scan (NCCT) confers significant advantages compared to kidney-ureter-bladder film (KUB) only. We reviewed the medical records of 307 cases (165 men, 142 women) with renal and ureteral stones treated consecutively at our institution with ESWL between 2020 and 2023...

PURPOSE: An abnormal lower urinary tract poses significant challenges for transplant surgeons. Besides the ureteral anastomosis to an ileal conduit, there are diverse complex reconstructive solutions. Due to its rarity, standardization and teaching of complex urinary diversion is extremely difficult. METHODS: The indications and outcomes of complex urinary diversions after kidney transplantation (KT) were retrospectively investigated at eight urologic transplant centers including a current follow-up...

The authors examined a 25-year-old man with a combined rupture of the diaphragm and urinary bladder following blunt trauma to the abdomen. The presence of hematuria, suprapubic tenderness, and elevated serum urea and creatinine levels in this patient raised suspicion of urinary bladder rupture. Documentation of bowel gas shadows on the chest x-ray suggested underlying diaphragm injury. A computed tomogram of the thorax and abdomen confirmed the tear in the left hemidiaphragm with intrathoracic herniation of abdominal contents; however, it failed to detect the intraperitoneal urinary bladder rupture...

BACKGROUND: Contrast-enhanced computed tomography (CECT) provides much more information compared to non-enhanced CT images, especially for the differentiation of malignancies, such as liver carcinomas. Contrast media injection phase information is usually missing on public datasets and not standardized in the clinic even in the same region and language. This is a barrier to effective use of available CECT images in clinical research. PURPOSE: The aim of this study is to detect contrast media injection phase from CT images by means of organ segmentation and machine learning algorithms...

INTRODUCTION: Opinions differ on what drugs have both a rationale and a development potential for the treatment of bladder storage dysfunction. AREAS COVERED: In the present review, the focus is given to small molecule blockers of TRP channels (TRPV1, TRPV4, TRPA1, and TRPM8), P2×3receptor antagonists, drugs against oxidative stress, antifibrosis agents, cyclic nucleotide - dependent pathways, and MaxiK±channel - gene therapy. EXPERT OPINION: TRPV1 channel blockers produce hypothermia which seems to be a problem even with the most efficacious second-generation TRPV1 antagonists...

Small-cell carcinoma of the bladder (SCCB) is an uncommon and aggressive malignancy of the urinary tract. Its clinical presentation often mimics that of other bladder neoplasms, posing a diagnostic challenge. This case report presents a rare instance of SCCB in a 65-year-old female, shedding light on the diagnostic journey and emphasizing the need for heightened and prompt clinical suspicion due to its aggressive nature. The patient presented to the urological department with hematuria, dysuria, and hypogastric pain...

Bladder calculi commonly develop in patients with poor bladder emptying or those with retained foreign bodies within the bladder, leading to irritative voiding symptoms, hematuria, and an increased likelihood of refractory urinary tract infections. While many techniques exist for the treatment of bladder calculi, including endoscopic and open-surgical approaches, our novel technique may help manage exceptionally large or difficult-to-treat bladder calculi effectively. We present three patients with symptomatic bladder calculi ranging from 1...

Hypothermia is defined as a significant drop in core body temperature below 35°C (95°F). It is traditionally staged as mild, moderate, severe, and profound at temperatures of 35°C to 32°C (95°F to 89.6°F), 32°C to 28°C (89.6°F to 82.4°F), <28°C (<82.4°F), and <24°C (75.2°F), respectively. It can also be classified into the same stages by clinical presentations. We present a patient that fits into two different stages based on core body temperature and clinical presentation...
