Summary: Overactive bladder (OAB) is a common and debilitating condition with urgency symptoms that have detrimental effects on quality of life and survival. The exact etiology of OAB remains mysterious and no curative therapeutic approaches have been identified. OAB symptoms are often overlooked and inadequately treated in neurological diseases, but recent findings have provided a comprehensive overview of the association between OAB symptoms and various neurological disorders.

Summary: This study summarizes the guidelines from the European Association of Urology on the management of non-neurogenic female lower urinary tract symptoms, including underactive bladder, bladder outlet obstruction, and nocturia.

Summary: The CMMG model is a mechanistic approach for simulating bladder mechanics, voiding function, and tissue adaptations in response to altered biomechanical conditions. Calibrated with data from healthy male rat urinary bladders, the model successfully simulates the growth and remodeling response to partial bladder outlet obstruction (BOO).

Summary: We present a constrained mixture-micturition-growth (CMMG) model for simulating bladder mechanics, voiding function, and tissue adaptations. This model provides a mechanistic approach for investigating the bladder's structure-function relationship and its adaption in pathological conditions. It has the potential to be used as a tool for developing new treatments for bladder diseases.

Summary: This article focuses on detrusor underactivity (DU) with bladder outlet obstruction (BOO) in male patients, discussing the pathophysiology, evaluation, treatment and predictors for successful BOO surgery. The article highlights the lack of understanding and research on DU from BOO, as well as the need for effective and safe medication to restore bladder contractility. Further research to explore the unknown aspects of DU is deemed valuable.

Summary: This study aimed to explore the impact of pelvic reconstruction surgery on the relationship between POP and OAB, as well as the effects of preoperative vaginal estrogen supplement on vaginal tissue. The results showed that pelvic reconstruction surgery significantly improved OAB symptoms, and short-term preoperative supplement of topical estrogen led to alterations in vaginal epithelium.

Summary: The objective of this study was to assess the objective association between bladder outlet obstruction (BOO) and abnormal sensation parameters during filling cystometry in men. The results indicated a strong association between bladder oversensitivity and BOO in men. Men with first desire to void (FDV) <140 mL had a significantly increased probability of being obstructed.

Summary: Non-invasive biomarkers are still needed to identify patients with bladder outlet obstruction (BOO)-related dysfunction. In a study involving rats and BPH patients, it was found that FGF2 is involved in the development of bladder hypertrophy in partial BOO and is positively correlated with prostate volume in BPH patients. BDNF, on the other hand, showed no correlation with prostate volume, age, or BMI.

Summary: This study investigates the urinary beta 3-adrenoceptor concentration as a biomarker for overactive bladder (OAB) and predictor of treatment outcomes in women receiving the beta 3-adrenoceptor agonist mirabegron. The results suggest that urinary beta 3-adrenoceptor concentration may be a sensitive biomarker for OAB, and mirabegron treatment improves OAB symptoms and health-related quality of life.

Summary: This research explores the neurotoxicity of low-dose cyclophosphamide on the urinary bladder of rats through in vivo and in vitro studies. The results indicate that low-dose CYP treatment induces nerve injury, leading to bladder pain and overactive bladder in female rats. The up-regulation of Nlrp6 and Casp11 may contribute to these pathological changes.

Summary: Few studies have been conducted on markers for the prevalence of lower urinary tract symptoms (LUTS). This study revealed that hypercalciuria is significantly associated with OAB, nocturia, and nocturnal polyuria.

Summary: The study aimed to evaluate the relationship between OAB medication adherence and different types of medication with UTI risk. The study found that during the follow-up period, neither adherence nor different types of medication had an impact on UTI risk, regardless of UTI history or sex.

Summary: It is not possible to diagnose the cause of voiding difficulty based on medical history alone. Different urinary problems may have overlapping symptoms. To differentiate between underactive bladder and bladder outlet obstruction as the underlying cause of lower urinary tract symptoms, invasive urodynamic study of the bladder is often required.

Summary: This is the first meta-analysis on the diagnostic value of non-invasive methods for diagnosing bladder outlet obstruction (BOO) in men with lower urinary tract symptoms (LUTS). The results showed that detrusor wall thickness (DWT) and penile cuff test (PCT) had high accuracy for diagnosing BOO, with DWT using 2 mm as the cut-off showing the highest level of accuracy.

Summary: Inflammation is a key factor in bladder outlet obstruction pathology, and understanding the various specialized proresolving mediators (SPMs) and their receptors in the bladder holds promise for developing new ways to address inflammation.
