Botox in below knee amputation for the management of post-operative contracture: a systematic review.

During the 1970s, scientists first used botulinum toxin to treat strabismus. While testing on monkeys, they noticed that the toxin could also reduce wrinkles in the glabella area. This led to its widespread use in both medical and cosmetic fields. The objective of the study was to evaluate the potential use of Botox in managing post-operative contracture after below-knee amputation. We conducted a systematic review In Pubmed, Cochrane Library, Embase, and Google Scholar using the MESH terms Botox, botulinum toxin, post-operative contracture, amputation, and below knee amputation. Our goal was to evaluate the potential use of Botox to manage post-operative contracture in patients who have undergone below-knee amputation. Our findings show evidence in the literature that Botox can effectively manage stump hyperhidrosis, phantom pain, and jumping stump, but no clinical trial has been found that discusses the use of Botox for post-operative contracture. Botox has been used in different ways to manage spasticity. Further studies and clinical trials are needed to support the use of Botox to manage this complication.

Efficacy of botulinum toxin A combined with extracorporeal shockwave therapy in post-stroke spasticity: a systematic review.

Objectives: In recent years, there has been an increase in the number of randomized clinical trials of BTX-A combined with ESWT for the treatment of post-stroke spasticity. This has made it possible to observe the benefits of combination therapy in clinical practice. Therefore, this paper reviews the effectiveness of BTX-A in combination with ESWT for the treatment of post-stroke spasticity. Methods: By October 2023, a systematic review was conducted in the databases PubMed, Cochrane, Embase, Medline, Web of Science, China National Knowledge Infrastructure, Wan Fang Database, China Biology Medicine disc and China Science and Technology Journal Database were systematically searched. We included randomized controlled trials that reported outcome metrics such as MAS, FMA, and MBI score. Studies were excluded if MAS was not reported. The quality of the included studies was assessed by the Cochrane Collaboration's tool for assessing risk of bias, and the AMSTAR quality rating scale was selected for self-assessment. Results: A total of 70 articles were included in the initial search, and six were ultimately included. The results of the included studies showed that the combination therapy was effective in reducing MAS scores and improving FMA and MBI scores in patients with spasticity compared to the control group. Combination therapy has also been shown to improve joint mobility and reduce pain in spastic limbs. Conclusion: Cumulative evidence from clinical randomized controlled trial studies suggests that the combination therapy is effective in reducing lower limb spasticity and improving mobility after stroke. However, more clinical trials are still needed to corroborate the evidence regarding the efficacy of BTX-A combined with shockwave therapy. Systematic Review Registration: The system review can be searched in the PROSPERO database (CRD42023476654).

The gold protocol: A combined treatment approach for neck rejuvenation with calcium hydroxyapatite, botulinum toxin, and hyaluronic acid in the same session.

BACKGROUND: The signs of aging seem to be more visible on the neck compared to other locations, especially if a patient has already gone through facial rejuvenation procedures. Treatment of the aging neck imposes a challenge to the clinician, since one single approach is usually not enough to achieve the desired result, requiring multiple injections and sessions, which apart from being painful for the patients, is time-consuming for the clinician. AIM: To describe the use of calcium hydroxyapatite, incobotulinum toxin type A and Cohesive poly-densified matrix hyaluronic acid diluted in the same syringe and injected in the same session for neck rejuvenation. PATIENTS AND METHODS: Fifteen women, older than 18 years, with cervical skin flaccidity grade 1-4 in a previously validated 5-point rating scale (Dermatologic Surg, 2016; 42, S94), who sought neck rejuvenation were injected in this pilot study with a single session with a combined hybrid mixture of calcium hydroxyapatite, incobotulinum toxin type A, and Cohesive poly-densified matrix hyaluronic acid and followed up for 90-180 days. RESULTS: At the 4-month post injection evaluation, 93.3% of the patients presented at least 1-grade improvement in the 5-point scale as evaluated by the investigator. No serious adverse events were reported, being most mild and transient in nature. CONCLUSION: CaHA, incoBonTA, and CPM-HA have complementary mechanisms of action and may be injected from the same syringe in the same session, boosting the final outcome, with high patient satisfaction, and ease of process for both patients and clinicians.

Retrograde cricopharyngeal dysfunction and treatment with botulinum toxin: a systematic review.

PURPOSE: Retrograde cricopharyngeal dysfunction (RCPD) is a disease first described systematically in 2019. The main symptom is inability to belch due to cricopharyngeal muscle dysfunction. Other symptoms include gurgling noises, chest pain, bloating, and excessive flatulence. This paper aims to describe RCPD, the aetiology and diagnosis, treatment options, follow-up, and treatment with botulinum toxin (BT). METHODS: A systematic review was done according to the PRISMA guidelines, using the databases PubMed, Embase, and Cochrane at 8/3/2024. The search combined BT with different descriptions of RCPD. All papers were screened by two authors. RESULTS: 120 papers were identified in the search. After screening 13 papers describing 472 patients in total were included. Mean age was 29.3 years with 51.1% men. Diagnosis was established in 82.4% of the cases by symptomatology, 2.1% by high-resolution manometry, and 15.3% by oesophagoscopy. The mean amount of BT was 66 units (U). Mean follow-up time was 13 months. After 1-4 weeks 93.7% had an effect post-treatment and 81.0% after 6 months. Common symptoms were inability to belch (99.8%), chest pain and/or bloating (95.4%), gurgling noises (84.9%), and excessive flatulence (75.9%). Common complications were mild and transient dysphagia (59.4%) and reflux (35.4%). CONCLUSION: The accumulated numbers of patients with RCPD indicates a growing attention to the plausible condition. Injection with BT is a good and safe treatment of RCPD. Most patients only experience mild and transient complications to the treatment. Much is still unknown about RCPD and conditions for setting the diagnosis needs to be evaluated and established internationally.

A Case Report of Herpes Zoster After Botulinum Toxin Injections.

This case report presents a rare occurrence of herpes zoster (HZ) outbreak in a 50-year-old male following botulinum toxin (BTX) type A injections. The patient developed burning swollen lesions on the left forehead four days after receiving BTX injections. Physical examination revealed papules and erosions in a dermatomal distribution. He was diagnosed with HZ and promptly treated with oral acyclovir. The lesions resolved within two weeks without complications. Previous literature reports a few similar HZ outbreaks following aesthetic treatments with BTX injections. The exact mechanism triggering varicella reactivation in these cases remains unclear. Prompt diagnosis and treatment of HZ are crucial in order to minimize outbreak duration and reduce complications. Physicians should maintain awareness of HZ as a potential complication following BTX injections.

Treatment modalities for paediatric functional daytime lower urinary tract disorders: an updated review.

Paediatric functional bladder disorders especially those causing daytime symptoms are a common cause of significant psychosocial and/or physical morbidity and impaired quality of life. Despite the availability of many therapeutic modalities, a significant number of children appear to be refractory to treatment and continue to have symptoms. In this review, we aim to evaluate the current evidence in the use of existing and novel therapeutic options for the management of daytime lower urinary tract disorders in children. We also aim to highlight the controversies around the terminology and diagnosis of paediatric lower urinary tract dysfunction (LUTD) and specific conditions. The article will then provide a reasonable critique of the existing and emerging treatment modalities in functional daytime LUTD in children including their mode of action, efficacy, indications, and recent advances. These include standard urotherapy, specific urotherapy comprised of biofeedback, alarm therapy and electrical neural stimulation and pharmacotherapy involving selective and non-selective anticholinergics, ß3 adrenergic agonists, alpha blockers and botulinum toxin. A better understanding of this common clinical problem may help clinicians achieve better profiling of these children's diagnoses to further enable specific, targeted treatment.

A review article about new treatment options for otherwise healthy children with long-term urinary symptoms occurring during the daytime Management of paediatric functional daytime LUT disorders is complex and may benefit from a combination of treatment modalities. Urotherapy and anticholinergics appear to be effective in the majority however, non-responders warrant careful re-evaluation to characterize the specific type of LUTD to target appropriate treatment. Various novel therapies and adjuncts have been shown effective and range from smartphone apps, bladder alarms, neuromodulation systems and more effective drug delivery systems. Despite being effective, non-selective antimuscarinics are less favoured for long-term use in children due to the side-effect profile. Therefore, more selective anticholinergics, ß3 agonists and combination treatment options are being evaluated to improve compliance while maintaining/enhancing treatment efficacy. Use of alpha blockers and intravesical injection of botulinum toxin have shown promising results especially in refractory cases.

Intramuscular versus intradermal botulinum toxin for forehead wrinkles: a review of side effects and efficacy.

Botulinum toxin type A (BTA) is a neurotoxin used for both cosmetic and non-cosmetic purposes. BTA is commonly administered as an intramuscular injection to treat wrinkles. However, when it comes to treating forehead wrinkles, intramuscular injection is associated with a greater rate of ptosis. Intradermal injection is currently thought to be a better alternative. We searched PubMed and Google Scholar for research articles published between 1989 and 2023 using the following keywords: "intradermal," "intramuscular," "botulinum toxin," and "forehead wrinkle." The search yielded three randomized controlled trials and a double-blind, split-face case report on 58 patients. We found that although intradermal and intramuscular injections have symmetrical anti-wrinkle effects, the former results in a lower rate of ptosis and a greater degree of pain.

Treatment of Frey Syndrome with Botulinum Toxin-A: A Practical Approach from Minor's Test to Injection.

Introduction: Frey's syndrome, described by Lucy Frey in 1923, is a unique condition characterized by sweating, flushing, and reddening as a direct response to mastication. This phenomenon results from the aberrant regeneration of postganglionic parasympathetic neurons originating from the auriculotemporal nerve and the subsequent acetylcholine secretion induced by masticatory stimuli. Although rare, this syndrome can have multiple underlying causes and is frequently observed, occurring in up to 65% of cases following lateral parotid resections. Additionally, it can less commonly manifest after neck dissection, facelift procedures, or be associated with diabetes mellitus. Method: This article outlines a comprehensive diagnostic algorithm for Frey's syndrome, which includes the utilization of the Minor-Starch-Iodine Test. This test is a key component in diagnosing the syndrome and is discussed in detail, providing insights into its procedure and interpretation. Additionally, the gold standard of treatment for established Frey's syndrome, botulinum toxin A, is thoroughly described, including its mechanism of action, administration, and potential side effects. Discussion: Finally, the article underscores the need for further research to enhance our understanding of Frey's syndrome, leading to better diagnostic methods and more tailored treatment options for patients.

Myofascial pain - A major player in musculoskeletal pain.

Myofascial pain is a soft tissue pain syndrome with local and referred musculoskeletal pain arising from trigger points. Myofascial pain and myofascial pain syndromes are among some of the most common acute and chronic pain conditions. Myofascial pain can exist independently of other pain generators or can coexist with or is secondary to other acute and chronic painful musculoskeletal conditions. Myofascial pain is most effectively treated with a multimodal treatment plan including injection therapy (known as trigger point injections, physical therapy, postural or ergonomic correction, and treatment of underlying musculoskeletal pain generators. The objectives of this review are to outline the prevalence of myofascial pain, describe the known pathophysiology of myofascial pain and trigger points, discuss the clinical presentation of myofascial pain, and present evidence-based best practices for pharmacologic, non-pharmacologic, and interventional treatments for myofascial pain.

Iatrogenic botulism cases after gastric and axillary application of botulinum toxin and review of literature.

INTRODUCTION: Iatrogenic botulism is a rare, serious disease that progresses with descending paralysis and develops after cosmetic or therapeutic botulinum toxin-A (BoNT-A) application. CASE PRESENTATIONS: In this case series; six cases of iatrogenic botulism followed up in our center are presented. Four of these developed after gastric BoNT-A and two after axillary BoNT-A application. RESULTS: The most important cause for the disease was the use of unlicensed products and high-dose toxin applications. The first symptoms were blurred vision, double vision, difficulty in swallowing, and hoarseness. Symptoms appeared within 4-10 days after the application of BoNT-A. Symptoms progressed in the course of descending paralysis in the following days with fatigue, weakness in extremities and respiratory distress. Diagnosis was based on patient history and clinical findings. The main principles of foodborne botulism therapy were applied in the treatment of iatrogenic botulism. If clinical worsening continued, regardless of the time elapsed after BoNT-A application, the use of botulinum antitoxin made a significant contribution to clinical improvement and was recommended. CONCLUSIONS: Routine and new indications for BoNT-A usage are increasing and, as a result, cases of iatrogenic botulism will be encountered more frequently. Physicians should be alert for iatrogenic botulism in the follow-up after BoNT-A applications and in the differential diagnosis of neurological diseases that are presented with similar findings.

Compared to oxcarbazepine and carbamazepine, botulinum toxin type A is a useful therapeutic option for trigeminal neuralgia symptoms: A systematic review.

OBJECTIVES: This review aimed to compare the effectiveness of three treatments: BTX A, CBZ, and OXB, in managing trigeminal neuralgia (TN). MATERIAL AND METHODS: We conducted a thorough search for research articles related to our issue using specific keywords on several databases, including Cochrane Central Register of Controlled Trials, Science Direct, Scopus, PubMed, Elsevier, Springer Journals, Ovid Medline, EBSCO, and Web of Science. Our focus was on publications from 1965 to 2023. RESULTS: We retrieved 46 articles from the search and reviewed them carefully. Out of these, we selected 29 articles that met the inclusion criteria. Among the selected articles, 11 investigated the effects of CBZ and OXB, while 18 explored the impact of BTX A on the improvement of TN symptoms. The response rate ranged between 56% and 90.5% for CBZ and between 90.9% and 94% for OXB. The response rate for BTX A ranged between 51.4% and 100%. All these three treatments had a remarkable effect on the improvement of TN. Importantly, findings highlighted that side effects of CBZ and OXB could lead to treatment discontinuation in some cases, whereas BTX A's side effects have been minimal and less frequent. CONCLUSIONS: Consequently, BTX A emerges as a promising alternative for TN treatment. However, additional clinical trials are necessary to validate this finding, and further research is required to establish a standardized protocol for administering BTX A in TN.

A brief review of complex regional pain syndrome and current management.

Complex regional pain syndrome (CRPS) is a debilitating chronic pain condition that, although exceedingly rare, carries a significant burden for the affected patient population. The complex and ambiguous pathophysiology of this condition further complicates clinical management and therapeutic interventions. Furthermore, being a diagnosis of exclusion requires a diligent workup to ensure an accurate diagnosis and subsequent targeted management. The development of the Budapest diagnostic criteria helped to consolidate existing definitions of CRPS but extensive work remains in identifying the underlying pathways. Currently, two distinct types are identified by the presence (CRPS type 1) or absence (CRPS type 2) of neuronal injury. Current management directed at this disease is broad and growing, ranging from non-invasive modalities such as physical and psychological therapy to more invasive techniques such as dorsal root ganglion stimulation and potentially amputation. Ideal therapeutic interventions are multimodal in nature to address the likely multifactorial pathological development of CRPS. Regardless, a significant need remains for continued studies to elucidate the pathways involved in developing CRPS as well as more robust clinical trials for various treatment modalities.

Complex regional pain syndrome (CRPS) is a debilitating and complex condition that places a significant physical, psychological and emotional burden upon afflicted patients necessitating multi-modal approaches to treatment.The development of the Budapest criteria provided a robust and well-tested set of diagnostic criteria to aid clinicians in the diagnosis of CRPS.The pathophysiology of CRPS has been challenging to elucidate with numerous proposed mechanisms, altogether suggesting a multi-factorial process is involved in the development of this condition.Non-invasive treatments for CRPS are essential in addressing the physical limitations this disease can cause as well as addressing the significant psychological burden that involves increased incidence of depression and suicidal ideation.Invasive treatments offer promising results, especially when considering dorsal root ganglion stimulation; however, the need for more robust clinical trials remains, especially when considering a small portion of patients who have refractory CRPS resort to amputation to control their pain symptoms.

Aesthetic doctors' perception and attitudes toward tolerance in botulinum toxin.

BACKGROUND: Botulinum toxin is a crucial therapeutic tool with broad indications in both cosmetic and medical fields. However, the expanding cosmetic use and increased dosages of botulinum toxin have raised concerns about resistance, making it essential to study the awareness and management practices among healthcare professionals. METHODS: A survey was conducted among clinical physicians using botulinum toxin. The study investigated their experiences, awareness, and management practices related to toxin resistance. Real-time mobile app-based surveys were administered to clinicians attending the 45th International Academic Conference of the Korean Academy of Laser and Dermatology (KALDAT) on December 3, 2023. RESULTS: Among 3140 participants, 673 clinical physicians completed the survey. Of these, 363 clinicians (53.9%) reported experiencing botulinum toxin resistance. Regarding the resistance rate, 59.4% indicated less than 1%, 36% reported approximately 1%-25%, and 95.4% reported less than 25%. Efforts to prevent resistance included maintaining intervals of over 3 months (54.8%), using products with lower resistance potential (47.0%), employing minimal effective doses (28.2%), and minimizing re-administration (14.9%). CONCLUSION: In the South Korean aesthetic medicine community, a majority of clinical physician's report encountering botulinum toxin resistance. Given the potential loss of various benefits associated with resistance, there is a need to establish appropriate guidelines based on mechanistic studies and current status assessments. Educating clinicians on applicable guidelines is crucial.

Efficacy and safety of botulinum toxin A in the treatment of female pattern hair loss.

BACKGROUND: Female pattern hair loss (FPHL) is the most prevalent type of alopecia among adult women. Presently, topical minoxidil stands as the sole treatment endorsed by the FDA. Addressing cases of FPHL in individuals who develop contact dermatitis in response to minoxidil can pose a challenge for dermatologists. OBJECTIVE: To assess the efficacy and safety of subcutaneous injections of Botulinum Toxin Type A (BTA) in treating FPHL. METHODS: Enrolled outpatients with FPHL who exhibited an allergic reaction to minoxidil solution. Diagnosis of FPHL was established through clinical examination and trichoscopy. Inclusion criteria involved patients with no prior treatment within the last year and without any comorbidities. BTA, specifically 100 units, was mixed with 2 mL of 0.9% normal saline. Twenty injection target sites, spaced 2-3 cm apart, were symmetrically marked on the hairless area of the scalp. A dosage of five units was intradermally injected at each target site. Representative photographs and dermoscopic images of the scalp were captured before and after 3 months of treatment. RESULTS: A total of 10 FPHL, aged between 26 and 40 years, were included. The average age was 30.3 ± 4.64 years, and all patients had a positive family history of Androgenetic Alopecia. The average duration of the disease was 3.70 ± 1.42 years. According to patients' self-assessment, after 1 month of treatment, 10 FPHL patients reported experiencing moderate to marked improvement in symptoms related to scalp oil secretion. Three months later, dermatological assessments showed that three had mild improvement, six had no change, and one had a worsening condition. No adverse effects were observed. CONCLUSIONS: Our study suggests that the effectiveness of BTA for FPHL is limited to 3 months. However, it can be considered for tentative use after effective communication with patients. The long-term efficacy and safety of BTA in treating FPHL require further observation and study.

Parietal abdominal pain with lower leg discrepancy: a case report.

BACKGROUND: This report involves the first publication describing a case of parietal abdominal pain due to lower limb length discrepancy. CASE PRESENTATION: A Caucasian male patient in his 50s was referred to our rehabilitation department with chronic abdominal pain that began in childhood. This chronic pain was associated with episodes of acute pain that were partially relieved by grade 3 analgesics. The patient was unable to sit for long periods, had recently lost his job, and was unable to participate in recreational activities with his children. Investigations revealed contracture and hypertrophy of the external oblique muscle and an limb length discrepancy of 3.8 cm (1.5 inches) in the left lower limb. The patient was effectively treated with a heel raise, physiotherapy, intramuscular injection of botulinum toxin, and lidocaine. The patient achieved the therapeutic goals of returning to work, and reducing analgesic use. CONCLUSIONS: Structural misbalances, as may be caused by lower leg discrepancy, may trigger muscular compensations and pain. Complete anamnesis and clinical examination must not be trivialized and may reveal previously ignored information leading to a proper diagnosis.

Association analyses between the variants of SNAP25, SV2C and ST3GAL2 and the efficacy of botulinum toxin A in the treatment of the primary Meige syndrome.

Objective: Individual differences were observed in the clinical efficacy of Botulinum toxin A (BoNT-A) in the treatment of the primary Meige syndrome. Our study aimed to explore the potential associations between the clinical efficacy of BoNT-A in the treatment of the primary Meige syndrome and variants of SNAP25, SV2C and ST3GAL2, which are involving in the translocation of the BoNT-A in vivo. Methods: Patients with the primary Meige syndrome treated with BoNT-A were enrolled. Clinical efficacy was evaluated by the maximum improvement rate of motor symptoms and the duration of efficacy. Variants of SNAP25, SV2C and ST3GAL2 were obtained by Sanger sequencing. Another cohort diagnosed with primary cervical dystonia was also enrolled in the replication stage. Results: Among the 104 primary Meige syndrome patients, 80 patients (76.9%) had a good efficacy (the maximum improvement rate of motor symptoms ≥30%) and 24 (23. 1%) had a poor (the maximum improvement rate of motor symptoms <30%). As to the duration of efficacy, 52 patients (50.0%) had a long duration of efficacy (≥4 months), and 52 (50.0%) had a short (<4 months). In terms of primary Meige syndrome, SNAP25 rs6104571 was found associating with the maximum improvement rate of motor symptoms (Genotype: P = 0.02, OR = 0.26; Allele: P = 0.013, OR = 0.29), and SV2C rs31244 was found associating with the duration of efficacy (Genotype: P = 0.024, OR = 0.13; Allele: P = 0.012, OR = 0.13). Besides, we also conducted the association analyses between the variants and BoNT-A-related adverse reactions. Although, there was no statistical difference between the allele of SV2C rs31244 and BoNT-A-related adverse reactions, there was a trend (P = 0.077, OR = 2.56). In the replication stage, we included 39 patients with primary cervical dystonia to further expanding the samples' size. Among the 39 primary cervical dystonia patients, 25 patients (64.1%) had a good efficacy (the maximum improvement rate of motor symptoms ≥50%) and 14 (35.9%) had a poor (the maximum improvement rate of motor symptoms <50%). As to the duration of efficacy, 32 patients (82.1%) had a long duration of efficacy (≥6 months), and 7 (17.9%) had a short (<6 months). Integrating primary Meige syndrome and primary cervical dystonia, SV2C rs31244 was still found associating with the duration of efficacy (Genotype: P = 0.002, OR = 0. 23; Allele: P = 0.001, OR = 0. 25). Conclusion: In our study, SNAP25 rs6104571 was associated with the maximum improvement rate of motor symptoms in patients with primary Meige syndrome treated with BoNT-A, and patients carrying this variant had a lower improvement rate of motor symptoms. SV2C rs31244 was associated with duration of treatment in patients with primary Meige syndrome treated with BoNT-A and patients carrying this variant had a shorter duration of treatment. Patients with primary Meige syndrome carrying SV2C rs31244 G allele have an increase likelihood of BoNT-A-related adverse reactions. Involving 39 patients with primary cervical dystonia, the results further verify that SV2C rs31244 was associated with duration of treatment and patients carrying this variant had a shorter duration of treatment.

Clinical Application of Botulinum Toxin A on Nasal Reconstruction with Expanded Forehead Flap for Asian Patients.

BACKGROUND: Because of its unique advantages, frontal expansion has become a common tool for Asian nasal reconstruction, but it has the limitations of prolonging the duration and pain in the expansion area. Based on the fact that the denervation effect of botulinum toxin type A (BTX-A) has been widely used in the reconstruction of superficial organs, we hypothesized that BTX-A would shorten the length of nasal reconstruction sequence and alleviate the discomfort of patients. METHODS: A comparative retrospective study was conducted of consecutive patients underwent sequential treatment of nasal reconstruction between June 2010 and July 2012. Data on demographics, BTX-A injection plan and expansion duration were collected and analyzed. Phased pain intensity outcomes were evaluated by visual analogue scale (VAS). Photographs were collected during the follow-up period. RESULTS: Thirty patients were enrolled in the study; 15 (50%) with and 15 (50%) without BTX-A pre-injection. Demographic data were homogeneous. The duration of the observation group (BTX-A pretreated) (133.87 ± 13.64 days) was significantly shortened versus the control group (164.27 ± 14.08 days, P<0.001). At the initial stage, no significant difference was found in the VAS scores (P=0.64). At the medium stage, the VAS score of the observation group (2.07 ± 0.80) was significantly lower than the control group (3.00 ± 0.53, P<0.01). At the terminal stage, the VAS score of the observation group (1.93 ± 0.59) was significantly lower than the control group (2.73 ± 0.70) but with a narrower disparity. CONCLUSION: Pre-injection of BTX-A is effective in shortening the duration of the expansion phase, as well as relieving the pain associated with expansion.

The use of Botulinum toxin in various urological conditions.

OBJECTIVE: Aim: The objective of this review paper is to comprehensively analyze and summarize the current understanding and clinical applications of Botulinum toxin in the field of urology. PATIENTS AND METHODS: Materials and Methods: The materials and methods for this review paper involved an extensive literature search on the use of Botulinum toxin in urology. Multiple online databases such as PubMed, Web of Science, and Google Scholar were utilized to gather peer-reviewed articles, clinical trials, and relevant books published within the last decades. A few articles used in the review come from before 21 century because the information is essential to fully describe the topic. Studies were selected based on their relevance to the topic, with a focus on those that reported on the clinical applications of Botulinum toxin in urology - we use information from other review papers, clinical trials and research papers. To expand the database, we have looked through the literature not only in English but also other languages. Thanks to this method we were able to compare the results from different countries and scientific groups all over the world. Data extracted from these sources were then analyzed and synthesized to provide a comprehensive overview of the subject matter. CONCLUSION: Conclusions: In conclusion, Botulinum toxin has shown significant promise and utility in the field of urology. Its ability to effectively relax muscles has led to its application in a variety of urological conditions, including NDO, OAB, BPS/IC, DSD, BPH, CPP, and PE. The effectiveness and safety of Botulinum toxin have been demonstrated in numerous studies, providing a robust evidence base for its clinical use. However, further research is needed to optimize the administration methods, dosage, and treatment protocols. Additionally, more randomized controlled trials are required to establish the long-term safety and efficacy of Botulinum toxin, especially for conditions for which the current data is limited. Overall, Botulinum toxin represents a valuable tool in the urologist's armamentarium and is likely to continue to be an area of active research and development in the future.
