Background: Menopause is associated with an increased risk of kidney stone disease (KSD). However, for postmenopausal women, how to avoid KSD has rarely been studied. The aim of this study was to explore whether drinking tea is associated with a reduction in the prevalence of KSD in postmenopausal women.

Article Synopsis
  • Phthalates, commonly found in plastics, may negatively impact kidney health, particularly through oxidative stress, but their link to kidney stones (urolithiasis) is not well established.
  • A case-control study with 285 patients who have calcium urolithiasis and 594 healthy controls examined urinary levels of phthalate metabolites and biomarkers for oxidative stress and early kidney injury.
  • Results showed that kidney stone patients had higher levels of phthalate metabolites and biomarkers of oxidative stress and injury, indicating a potential increased risk of urolithiasis linked to phthalate exposure.

Accumulating evidence suggests a link between vascular endothelial growth factor (VEGF), erectile dysfunction (ED), and metabolic syndrome (Mets), possibly because VEGF can alter the physiological pathways involved in the regulation of endothelial cell proliferation. This study aimed to investigate the genetic susceptibility of VEGF 2578C>A polymorphism to the development of ED and Mets. Collected data included five-item International Index of Erectile Function (IIEF-5), components of Mets, and VEGF 2578C>A polymorphism.

Article Synopsis
  • Penile enlargement procedures, particularly injections of liquid silicone, can lead to severe long-term complications, as demonstrated by a patient who developed painful inflammatory granulomas after such a treatment.
  • Over time, the patient's condition deteriorated, leading to significant impairment of sexual function and ultimately a diagnosis of penile squamous cell carcinoma (SCC) due to chronic inflammation.
  • This case highlights the need for awareness of the serious risks associated with cosmetic penile procedures, as managing penile SCC is more complex and requires more aggressive surgical intervention than treating granulomas.

Background And Aims: Metabolic dysfunction-associated fatty liver disease (MAFLD) has emerged as a valuable marker for identifying individuals at increased risk of metabolic dysfunction, liver-related complications, and cardiovascular disease. However, the association between MAFLD and testosterone deficiency (TD) in aging men remains poorly understood. This study aimed to investigate the association between MAFLD and the risk of TD in aging Taiwanese men, with a specific focus on those without metabolic syndrome (MetS).

Background: Tobacco use and secondhand smoke (SHS) are risk factors of kidney stone disease (KSD). The hypothesis is that tobacco produces chemicals that increase oxidative stress and vasopressin, which leads to decreased urine output, and contributes to stone formation. The aim of this study was to examine the effects of smoking and SHS on the development of KSD.

Lower urinary tract symptoms (LUTS), such as urgency, urinary incontinence, and/or difficulty voiding, hamper the quality of life (QoL) of patients with spinal cord injury (SCI). If not managed adequately, urological complications, such as urinary tract infection or renal function deterioration, may further deteriorate the patient's QoL. Botulinum toxin A (BoNT-A) injection within the detrusor muscle or urethral sphincter yields satisfactory therapeutic effects for treating urinary incontinence or facilitating efficient voiding; however, adverse effects inevitably follow its therapeutic efficacy.

Purpose: The association between menopause, postmenopausal hormone therapy, and kidney stone disease has long been a topic of discussion and is still unclear. Moreover, most previous research has focused on Caucasians. Therefore, we aimed to explore this issue in an Asian population.

(1) Background: The current gold standard treatment of bladder cancer is conventional transurethral resection of the bladder tumor (CTURBT) using monopolar or bipolar resectoscopes. Laser en-bloc resection of the bladder tumor (LERBT) could achieve a higher quality of the specimen, reduce perioperative complications, and decrease the recurrence rate. Here, we compare the efficacy and safety of en-bloc Vela laser resection versus the conventional monopolar/bipolar resection; (2) Methods: A total of 100 clinically cT1-2 patients with bladder cancer were retrospectively reviewed in this study.

Article Synopsis
  • Environmental exposure to melamine can lead to oxidative stress and kidney damage, particularly in calcium urolithiasis patients.
  • Specific single-nucleotide polymorphisms (SNPs) in genes like MnSOD may increase susceptibility to these effects, with distinct alleles linked to higher risks.
  • The study found that individuals with certain genetic variants had significantly increased risks of elevated oxidative stress and kidney injury when exposed to high levels of melamine in their urine.

We aimed to examine the association between metabolic syndrome and the risk of kidney stone development in a large-scale community-based cohort. A total of 121,579 participants enrolled in the Taiwan Biobank were analyzed. They were divided into two groups on the basis of presence of metabolic syndrome.

Postmenopausal women with ovary hormone deficiency (OHD) are subject to overactive bladder (OAB) symptoms. The present study attempted to elucidate whether low-intensity extracorporeal shock wave therapy (LiESWT) alters bladder angiogenesis, decreases inflammatory response, and ameliorates bladder hyperactivity to influence bladder function in OHD-induced OAB in human clinical trial and rat model. The ovariectomized (OVX) for 12 months Sprague-Dawley rat model mimicking the physiological condition of menopause was utilized to induce OAB and assess the potential therapeutic mechanism of LiESWT (0.

Research indicates smoking increases the risk of various kidney diseases, although the risk of developing kidney stone disease in non-smokers exposed to secondhand smoke is unknown. This study analyzed a total of 19,430 never-smokers with no history of kidney stone disease who participated in the Taiwan Biobank from 2008 to 2019. They were divided into two groups by secondhand smoke exposure; no exposure and exposure groups; the mean age of participants was 51 years, and 81% were women.

Background: The present study attempted to investigate the therapeutic effect and duration of low intensity extracorporeal shock wave therapy (LiESWT) on overactive bladder (OAB) symptoms, including social activity and the quality of life (QoL).

Methods: In this prospective, randomized, single-blinded clinical trial, 65 participants with OAB symptom were randomly divided into receive LiESWT (0.25 mJ/mm, 3000 pulses, 3 pulses/second) once a week for 8 weeks, or an identical sham LiESWT treatment without the energy transmission.

Low intensity extracorporeal shock wave therapy (Li-ESWT) has proven to be effective and safe for the treatment of various urological disorders including erectile dysfunction and chronic pelvic pain syndrome. In this study, we elucidated the therapeutic effect and possible mechanisms of Li-ESWT on diabetic bladder dysfunction (DBD) in a rat model. In all, thirty-two female Sprague-Dawley rats were divided into three groups: normal control (NC), diabetes mellitus (DM) control, and DM Li-ESWT.

Objectives: Non-alcoholic fatty liver disease (NAFLD) is suggested to be a precursor of metabolic syndrome (MetS) and could influence the risk of testosterone deficiency (TD). Fatty liver index (FLI) is a simple and useful screening tool for NAFLD. We determined the association between the risk of NAFLD assessed by FLI and TD in aging Taiwanese men, especially those without MetS.

BackgroundAndrogen deprivation therapy (ADT) is essential in the treatment of advanced and metastatic prostate cancer. As the correlation between hormone therapy and hypertension remains unclear and prostate cancer is less prevalent in the Asian population, the clinician should focus on not only anticancer therapy but also the side effects of the intervention and quality of life of these patients.ObjectiveThis study aimed to investigate the risk of subsequent hypertension in patients undergoing androgen deprivation therapy for prostate cancer.
