Abstract
Urgency urinary incontinence (UUI) refractory to medical treatment poses significant challenges despite advancements. This study evaluates the efficacy of intravesical botulinum toxin for UUI and identifies factors influencing treatment outcomes. Among 368 women receiving botulinum toxin injections, 74.5% achieved a complete discontinuation of pad usage. Predictors of efficacy included lower pre-treatment pad usage and the absence of prior sling placement. Patients often required repeat injections (60.3%), with younger age and satisfaction correlating with treatment repetition. The interval between injections averaged 18 months, influenced by logistical challenges and patient preferences. Despite concerns about diminishing efficacy, subjective perceptions did not align with objective findings. Limitations include retrospective analysis and heterogeneous clinical records. In conclusion, intravesical botulinum toxin is effective for UUI, with pre-treatment pad usage and sling placement history influencing outcomes and patient characteristics influencing treatment repetition.

Curr Urol 2024; 18:49-54. [PMID: 38505153 PMCID: PMC10946635 DOI: 10.1097/cu9.0000000000000156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Accepted: 02/20/2022] [Indexed: 11/07/2022] Open
Abstract
Objective The aim of this study was to evaluate the feasibility of intravesical instillation of platelet-rich plasma (PRP) to treat interstitial cystitis/bladder pain syndrome (IC/BPS). Materials and methods Twenty PRP samples were tested in vitro for stability after exposure to urine samples with different pH. A pilot study involving 21 female patients with IC/BPS was conducted, and 6 weekly doses of autologous PRP (50 mL) were administered. Patients were followed up at the 2nd, 4th, 8th, and 12th weeks after terminating instillation. The primary endpoint was the visual analog scale (VAS) for pain, and the secondary endpoints included the IC symptom index, IC problem index of the O'Leary-Sant questionnaire and global response assessment, urine culture, and uroflowmetry. Success was defined as a reduction in VAS by 30% or more compared with basal level, and adverse events were recorded. Results The mean ± SD of VAS was significantly reduced compared with basal level (4.4 ± 2.6 vs. 8.8 ± 1.1, respectively, p = 0.001). Meanwhile, 80% of cases were considered successful, with a 50.1% reduction in the mean score compared with the basal level. The mean ± SD of IC symptom index and IC problem index significantly improved compared with the basal level. Global response assessment was markedly, moderately, and slightly improved in 2 (10%), 10 (50%), and 5 (25%) patients, respectively, and showed no change in 3 (15%). Three patients had positive urine cultures at follow-up, but 1 withdrew after 2 sessions because of a lack of efficacy. Conclusions Repeated intravesical instillation of PRP could be considered an effective and safe approach for treating IC/BPS.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a debilitating disease that induces mental stress, lower urinary symptoms, and pelvic pain, therefore resulting in a decline in quality of life. The present diagnoses and treatments still lead to unsatisfactory outcomes, and novel diagnostic and therapeutic modalities are needed. Although our understanding of the etiology and pathophysiology of IC/BPS is growing, the altered permeability of the impaired urothelium, the sensitized nerves on the bladder wall, and the chronic or intermittent sensory pain with inaccurate location, as well as pathologic angiogenesis, fibrosis, and Hunner lesions, all act as barriers to better diagnoses and treatments. This study aimed to summarize the comprehensive information on IC/BPS research, thereby promoting the progress of IC/BPS in the aspects of diagnosis, treatment, and prognosis. According to diverse international guidelines, the etiology of IC/BPS is associated with multiple factors, while the presence of Hunner lesions could largely distinguish the pathology, diagnosis, and treatment of non-Hunner lesions in IC/BPS patients. On the basis of the diagnosis of exclusion, the diverse present diagnostic and therapeutic procedures are undergoing a transition from a single approach to multimodal strategies targeting different potential phenotypes recommended by different guidelines. Investigations into the mechanisms involved in urinary symptoms, pain sensation, and bladder fibrosis indicate the pathophysiology of IC/BPS for further potential strategies, both in diagnosis and treatment. An overview of IC/BPS in terms of epidemiology, etiology, pathology, diagnosis, treatment, and fundamental research is provided with the latest evidence. On the basis of shared decision-making, a multimodal strategy of diagnosis and treatment targeting potential phenotypes for individual patients with IC/BPS would be of great benefit for the entire process of management. The complexity and emerging evidence on IC/BPS elicit more relevant studies and research and could optimize the management of IC/BPS patients.

Abstract
A shock wave (SW), which carries energy and propagates through a medium, is a type of continuous transmitted sonic wave that can achieve rapid energy transformations. SWs have been applied for many fields of medical science in various treatment settings. In urology, high-energy extracorporeal SWs have been used to disintegrate urolithiasis for 30 years. However, at lower energy levels, SWs enhance the expression of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), proliferating cell nuclear antigen (PCNA), chemoattractant factors, and the recruitment of progenitor cells, and inhibit inflammatory molecules. Low energy extracorporeal shock wave (LESW) therapy has been used in urology for treating chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), interstitial cystitis/bladder pain syndrome (IC/BPS), overactive bladder, stress urinary incontinence, and erectile dysfunction through the mechanisms of anti-inflammation, neovascularization, and tissue regeneration. Additionally, LESW have been proven to temporarily increase tissue permeability and facilitate intravesical botulinum toxin delivery for treating overactive bladders in animal studies and in a human clinical trial. LESW assisted drug delivery was also suggested to have a synergistic effect in combination with cisplatin to improve the anti-cancer effect for treating urothelial cancer in an in vitro and in vivo study. LESW assisted drug delivery in uro-oncology is an interesting suggestion, but no comprehensive clinical trials have been conducted as of yet. Taken together, LESW is a promising method for the treatment of various diseases in urology. However, further investigation with a large scale of clinical studies is necessary to confirm the real role of LESW in clinical use. This article provides information on the basics of SW physics, mechanisms of action on biological systems, and new frontiers of SW medicine in urology.

Abstract
Botulinum neurotoxin (BoNT/A) is an FDA and NICE approved second-line treatment for overactive bladder (OAB) in patients either not responsive or intolerant to anti-cholinergic drugs. BoNT/A acts to weaken muscle contraction by blocking release of the neurotransmitter acetyl choline (ACh) at neuromuscular junctions. However, this biological activity does not easily explain all the observed effects in clinical and non-clinical studies. There are also conflicting reports of expression of the BoNT/A protein receptor, SV2, and intracellular target protein, SNAP-25, in the urothelium and bladder. This review presents the current evidence of BoNT/A's effect on bladder sensation, potential mechanisms by which it might exert these effects and discusses recent advances in understanding the action of BoNT in bladder tissue.

The Effect of Low-intensity Shockwave Therapy on Non-neurogenic Lower Urinary Tract Symptoms: A Systematic Review and Meta-analysis of Preclinical and Clinical Studies. Eur Urol Focus 2021; 8:840-850. [PMID: 33985934 DOI: 10.1016/j.euf.2021.04.021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 04/09/2021] [Accepted: 04/23/2021] [Indexed: 01/22/2023]
Abstract
CONTEXT Low-intensity shockwave therapy (LiST) has emerged as an effective treatment for pain in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), and it has been postulated that LiST may also be effective in patients with lower urinary tract symptoms (LUTS). OBJECTIVE To perform a systematic review and meta-analysis of experimental and clinical studies exploring the effect of LiST on LUTS in an attempt to provide clinical implications for future research. EVIDENCE ACQUISITION We systematically searched PubMed, Cochrane Library, and Scopus databases from inception to March 2021 for relevant studies. We provided a qualitative synthesis regarding the role of LiST in LUTS and performed a single-arm, random-effect meta-analysis to assess the absolute effect of LiST on LUTS only in patients with CP/CPPS (PROSPERO: CRD42021238281). EVIDENCE SYNTHESIS We included 23 studies (11 experimental studies, seven nonrandomized controlled trials [non-RCTs], and five RCTs) in the systematic review and seven in the meta-analysis. All experimental studies were performed on rats with LUTS, and the clinical studies recruited a total of 539 participants. In patients with CP/CPPS, the absolute effect of LiST on maximum flow rate and postvoid residual was clinically insignificant. However, the available studies suggest that LiST is effective for the management of pain in patients with either CP/CPPS or interstitial cystitis/bladder pain syndrome. Additionally, LiST after intravesical instillation of botulinum neurotoxin type A may enhance its absorption and substitute botulinum neurotoxin type A injections in patients with overactive bladder. Furthermore, the available evidence is inconclusive about the role of LiST in patients with benign prostatic obstruction, stress urinary incontinence, or underactive bladder/detrusor hypoactivity. CONCLUSIONS LiST may be effective for some disorders causing LUTS. Still, further studies on the matter are necessary, since the available evidence is scarce. PATIENT SUMMARY Low-intensity shockwave therapy represents a safe, easily applied, indolent, and repeatable on an outpatient basis treatment modality that may improve lower urinary tract symptoms.

Abstract
CONTEXT A considerable number of studies addressing the management of lower urinary tract symptoms (LUTS) have been published since 2018. OBJECTIVE To review the key studies involving pharmacological and neuromodulation treatment of LUTS published from 2018 onward. EVIDENCE ACQUISITION We followed the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement. We conducted an Embase/PubMed search of English literature with the words "OAB" or "LUTS" matched with several different treatment modalities. The search ranged between January 2018 and January 2020. All retrieved papers were first reviewed by title and abstract, yielding a total of 236 papers. Additional manuscripts, such as those presented at major meetings, were also included. After revision, 46 publications were included. EVIDENCE SYNTHESIS Papers on β3-adrenoreceptor agonists were most abundant. The efficacy and safety of mirabegron in monotherapy and combination therapy were further confirmed by large observational studies and randomized control trials, including one carried out in elderly patients. The use of vibegron for overactive bladder (OAB) was effective and safe in pivotal clinical trials. More database analyses confirm the risk of dementia associated with long-term use of anticholinergics. Onabotulinum toxinA (OnabotA) and sacral neuromodulation provided similar improvement for incontinence in OAB patients at a 2-yr follow-up. Retrospective studies show that OnabotA is effective in men with OAB. New subcutaneous or transcutaneous devices for tibial nerve stimulation were investigated. The potential role of gene therapy in LUTS was assessed in a pilot study. CONCLUSIONS Important progresses occurred in the pharmacological and neuromodulation treatments of LUTS, which may change clinical practice. Inoculation of gene vectors was investigated for the first time. PATIENT SUMMARY The investigation in the therapeutic field of lower urinary tract symptoms is active. The search for the best option for each patient continues. This systematic review summarizes the findings of the most recent and relevant studies in the field.

Therapeutic Effect of Botulinum Toxin A on Sensory Bladder Disorders-From Bench to Bedside. Toxins (Basel) 2020; 12:toxins12030166. [PMID: 32182780 PMCID: PMC7150911 DOI: 10.3390/toxins12030166] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2020] [Revised: 02/27/2020] [Accepted: 03/06/2020] [Indexed: 12/22/2022] Open
Abstract
Bladder oversensitivity arises from several different conditions involving the bladder, bladder outlet, systemic or central nervous system diseases. Increase of the bladder sensation results from activation of the sensory receptors in the urothelial cells or suburothelial tissues. Medical treatment targeting the overactive bladder (OAB) or interstitial cystitis (IC) might relieve oversensitive bladder symptoms (frequency, urgency and pain) in a portion of patients, but a certain percentage of patients still need active management. Botulinum toxin A (BoNT-A) has been demonstrated to have anti-inflammatory and antinociceptive effects in bladder sensory disorders and has been shown effective in the reduction of bladder oversensitivity and the increase of functional bladder capacity. For patients with OAB, urgency and urinary incontinence improved, while in patients with IC, bladder pain could be relieved in association with reduction of bladder oversensitivity after BoNT-A intravesical injection. Histological evidence has confirmed the therapeutic mechanism and clinical efficacy of intravesical BoNT-A injection on patients with OAB or IC. Bladder oversensitivity can also be relieved with the instillation of liposome encapsulated BoNT-A or low energy show waves (LESWs), which enable the BoNT-A molecule to penetrate into the urothelium and suburothelial space without affecting the detrusor contractility. Liposome encapsulated BoNT-A or combined LESWs and BoNT-A instillation might be future treatment alternatives for bladder oversensitivity in sensory bladder disorders.

Therapeutic Efficacy of onabotulinumtoxinA Delivered Using Various Approaches in Sensory Bladder Disorder. Toxins (Basel) 2020; 12:toxins12020075.

Abstract
Cystoscopic onabotulinumtoxinA (onaBoNTA) intradetrusor injection is an efficient and durable modality for treating sensory bladder disorders. However, the inconvenience of using the cystoscopic technique and anesthesia, and the adverse effects of direct needle injection (e.g., haematuria, pain, and infections) have motivated researchers and clinicians to develop diverse injection-free procedures to improve accessibility and prevent adverse effects. However, determining suitable approaches to transfer onaBoNTA, a large molecular and hydrophilic protein, through the impermeable urothelium to reach therapeutic efficacy remains an unmet medical need. Researchers have provided potential solutions in three categories: To disrupt the barrier of the urothelium (e.g., protamine sulfate), to increase the permeability of the urothelium (e.g., electromotive drug delivery and low-energy shock wave), and to create a carrier for transportation (e.g., liposomes, thermosensitive hydrogel, and hyaluronan-phosphatidylethanolamine). Thus far, most of these novel administration techniques have not been well established in their long-term efficacy; therefore, additional clinical trials are warranted to validate the therapeutic efficacy and durability of these techniques. Finally, researchers may make progress with new combinations or biomaterials to change clinical practices in the future.
