Abstract
Background Vaginal erosion caused by the polypropylene mesh is a serious side effect, and the development of effective treatment methods is required. This study explored the potential of non-ablative vaginal erbium yttrium aluminum garnet (YAG) laser treatment (VEL) as a novel treatment approach. Methods In this study, VEL was performed on nine women who experienced vaginal erosion after undergoing treatment for pelvic organ prolapse (POP) with polypropylene mesh. These patients visited our hospital between April and December 2020. Using the Renovalase (SP Dynamis Fotona d.o.o., Ljubljana, Slovenia), the laser was applied to the entire vagina, with intensive irradiation focused on the erosion areas. Detailed analyses of symptoms before and after treatment, as well as histopathological changes, were conducted one year post-treatment. Results Nine women were referred to our hospital due to vaginal erosion caused by polypropylene mesh. The participants' average age was 73.2 years (range: 69-81 years), with four patients having undergone transvaginal mesh (TVM) surgery and five undergoing laparoscopic sacrocolpopexy (LSC). The average time from mesh insertion to treatment initiation was 7.2 years (range: 3-15 years), with eight patients having previously attempted mesh removal. Post-treatment, significant improvements were observed in managing vaginal erosion and related bleeding, corroborated by histopathological analysis confirming cell regeneration and tissue repair. These improvements also resulted in significant improvements in bleeding management and quality of life (QoL). Conclusion VEL suggests the possibility of being an effective treatment method for vaginal erosion caused by a polypropylene mesh. However, further research is needed because of the small sample size and the limitations inherent in the retrospective case series design.

Abstract
INTRODUCTION Lasers are commonly used for treating various vaginal/vulvar conditions. To date, there is to our knowledge no available literature review on the effects of different types of lasers for the treatment of women with vulvodynia, a condition that causes chronic pain in the vulvar area. OBJECTIVES We sought to review the literature and summarize the existing published evidence regarding the effects of lasers for the treatment of women with vulvodynia. METHODS A scoping review with a systematic search was conducted that included studies investigating the use of laser treatment in women with vulvodynia. The National Heart, Lung, and Blood Institute Study Quality Assessment Tools were used for the quality assessment. The type of laser, effects on pain and function, and participants' perceived improvement as well as adverse events were analyzed. RESULTS Eight studies investigating laser therapy were included in the analysis: 1 randomized controlled trial, 5 before-after studies, 1 nonrandomized intervention study, and 1 case report. Several types of laser therapies were identified, ranging from mild noninvasive photobiomodulation to more invasive ablative procedures. Of the 6 studies that included pain outcomes, 3 studies showed statistically significant improvements from baseline to follow-up, and 3 demonstrated a reduction in pain from subjectively interpreted data. Similarly, each of the 2 studies investigating sexual function also reported an improvement (based only on subjective interpretation). Of the 2 studies with a comparison group, neither study was adequately powered to detect between-group differences. Furthermore, 57%-78% of participants reported improvement, with 1 study showing a greater statistically significant improvement in the low-level laser therapy patient group compared to the sham laser group. Outcomes and adverse events varied depending on the type of laser used. CONCLUSIONS Although these studies demonstrated some benefits of laser therapy for the treatment of vulvodynia, these findings should be interpreted with caution given the scarcity of the included studies that were robust and sufficiently powered. Future research should focus on conducting well-designed randomized controlled trials to evaluate the efficacy of different types of lasers in the treatment of vulvodynia.

Abstract
Introduction Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic pain disorder characterized by urgency, frequency of urination, and pelvic pain. Women with IC/BPS often experience sexual dysfunction, vulvodynia, and vaginal health issues. Combined erbium and neodymium yttrium aluminum garnet (YAG) laser treatments targeting the vagina and vulva have shown promise in improving symptoms. Our study aims to investigate the effectiveness of these combined laser treatments in women with IC/BPS and vulvodynia. Methods Women diagnosed with vulvodynia and IC/BPS underwent combined laser treatment using vaginal erbium:YAG laser (VEL) and neodymium:YAG laser (Nd:YAG). Various parameters were evaluated, including the vulvodynia test, numeric rating scale (NRS-11) for pain, interstitial cystitis symptom index and problem index (ICSI and ICPI), pelvic pain and urgency/frequency symptom score (PUF), and mean urination volume/daily urination frequency in a three-day urination diary. Treatment was administered three times, with intervals of one month between each session, and follow-up evaluations were conducted at six and 12 months. All statistical analyses were designed and programmed by the AI chatbot GPT-4 (chatGPT-4). Results Fifteen female patients diagnosed with vulvodynia and IC/BPS were treated with three sessions of VEL + Nd:YAG. Significant improvements were observed in the vulvodynia test, NRS-11 scores, PUF, ICSI scores, ICPI scores, mean urination volume, and daily urination frequency at six and 12 months (p<0.01). Short-term improvements in IC/BPS pain scores correlated with improvements in the vulvodynia test (p=0.007), suggesting a synergistic effect. However, no significant correlations were found at 12 months. Conclusion Combined laser treatments targeting the vagina and vulva showed significant therapeutic effects in women with IC/BPS and vulvodynia. The addition of Nd:YAG to the VEL treatment enhanced outcomes. Short-term improvements in IC/BPS pain scores correlated with improvements in the vulvodynia test, indicating a synergistic effect. Long-term improvements in both vulvodynia and IC/BPS symptoms may occur independently. These findings highlight the importance of comprehensive approaches for treating coexisting vulvodynia and IC/BPS.

Abstract
Stress urinary incontinence (SUI) is increasing in elite female athletes (EFAs), affecting competition results and quality of life. Pelvic floor muscle training (PFMT) is the first-line treatment for SUI, and surgery is generally performed when PFMT is insufficient. However, in EFA, there are few cases in which surgery is performed and fewer reports. Therefore, there is no known general treatment strategy for EFA with SUI. In our study, a 23-year-old track-and-field medalist with severe SUI was successfully treated with a vaginal and urethral erbium-doped yttrium aluminum garnet laser (VEL + UEL). After 12 treatments over one year, urinary incontinence decreased from 300 mL or more in the 400 m track run before treatment to 0 mL. She did not experience any more problems during running or competition. There was no recurrence of SUI for three years, and the urethral pressure profile examination confirmed improvement. MRIs showed that the left puborectalis muscle was absent from the first visit. The urethra was oval with an anteroposterior outer diameter of 10 mm and a transverse outer diameter of 13 mm before treatment. However, after three years of treatment, both anteroposterior and transverse diameters became circular, measuring 11 mm. Vaginal wall thickness increased from 8 to 12 mm at the center of the height of the urethra, making it possible to support the urethra, and pretreated adipose tissue space between the urethra and vagina disappeared. It was noted that the uneven and fragile urethra/vagina, the presence of adipose tissue space, and the absence of the left puborectalis muscle may have been the cause of the SUI. One year of VEL + UEL treatment resulted in long-term improvement of SUI; MRI showed changes in the urethra and vagina.

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
Interstitial cystitis/bladder pain syndrome (IC/BPS) is often associated with vulvodynia and poor vaginal health. IC/BPS causes pelvic and bladder pain and urinary symptoms, which considerably reduce the quality of life. To date, this condition has no definitive cure. Local estrogen therapy (LET) has been proposed as a treatment for vulvodynia and poor vaginal health to improve the symptoms of IC/BPS. However, chronic LET could be contraindicated or not desired in some patients. The present study reports the case of a 55-year-old postmenopausal woman with IC/BPS who was successfully treated with combined vaginal erbium (VEL)/neodymium (Nd:YAG) laser (VEL+Nd:YAG) therapy. The patient presented with a five-year history of pelvic pain and urinary frequency. Direct approaches for the bladder (such as hydrodistension, anticholinergic drugs, and transurethral Hunner lesion ablation/cauterization) were conducted with inconsistent results. Immediately prior to the patient's presentation, LET was administered for 12 weeks; however, this therapy resulted in mild improvement and poor patient satisfaction. After presentation, VEL+Nd:YAG therapy was conducted once a month for three months. The patient reported considerable decrease in pain during urination. The improved symptoms were maintained for six months after the last therapy session. These results suggest that VEL+Nd:YAG therapy is an effective method for improving symptoms in patients with IC/BPS.

Abstract
INTRODUCTION AND HYPOTHESIS The Vaginal Health Index Score (VHIS) and vulvodynia swab tests are used to assess vaginal health and vulvodynia. However, few studies have used these tests in patients with interstitial cystitis/bladder pain syndrome (IC/BPS). IC/BPS is a chronic, debilitating disorder, characterised by urinary frequency, urinary urgency and pelvic pain. It adversely affects organs adjacent to the urinary system, leading to complications of sexual dysfunction. This study was aimed at understanding sexual dysfunction in patients with IC/BPS, as well as deterioration of vaginal health and vulvodynia. METHODS This study compared the vaginal health of IC/BPS patients with that of asymptomatic control individuals. The Pain Urgency Frequency (PUF) score, Female Sexual Function Index (FSFI), VHIS, and vulvodynia swab tests, were used as tools. The PUF and FSFI are questionnaire-based surveys of bladder symptoms and sexual function respectively. VHIS evaluation and vulvodynia swab tests are performed by physicians. The PUF was used to assess baseline IC/BPS symptoms to validate the patient population, and FSFI, vulvodynia swab tests and VHIS were used to determine between-group differences. RESULTS Thirty-seven patients were recruited in each group. The IC/BPS group had a higher PUF score (18.19±3.51 vs 3.56±2.35; p<0.05), worse total FSFI (15.72±4.46 vs 26.3±4.93; p<0.05), and worse vulvodynia swab test and total VHIS (11.59±2.87 vs 22.05±3.05; p<0.05) scores than those of the control group. CONCLUSIONS Asian women with IC/BPS experienced greater sexual dysfunction, worsened vaginal health and increased vulvodynia compared with control individuals. Information on vaginal and vulva health is very useful in evaluating IC/BPS patients.
