Predictive factors for the efficacy of Er:YAG laser treatment of urinary incontinence

Safety and Efficacy of Erbium: Yttrium-Aluminum-Garnet Laser Treatment in Chinese Women with Mild-to-Moderate Stress Urinary Incontinence

Background: This study aims to evaluate the safety and efficacy of erbium:yttrium-aluminum-garnet (Er:YAG) laser treatment in female patients with mild-to-moderate stress urinary incontinence (SUI). Methods: From July 2018 to June 2020, 72 female patients with mild-to-moderate SUI were enrolled in this study. A baseline assessment was conducted, which included a 1-hour pad test, the validated International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), postvoid residual (PVR) testing, pelvic organ prolapse quantification (POP-Q) testing, and a cough stress test. All patients underwent four sessions of Er:YAG laser treatment using a smooth mode. A reassessment was performed 6 months after treatment to evaluate the safety and efficacy of the Er:YAG laser. Results: All patients completed four clinic visits, with a 1-month interval, and were followed up for a minimum of 6 months. No severe adverse reactions were observed during the treatment process. The 1-hour pad test revealed a significant reduction in urinary leakage from baseline (6.30 ± 1.06 g) to the 6-month follow-up (2.70 ± 0.96 g, p < 0.001), with 34 of 72 (47.22%) patients achieving negative results. The ICIQ-UI-SF score significantly decreased from baseline to 6 months (10.82 ± 1.38 to 2.96 ± 0.52, p < 0.001). PVR experimental results showed a significant decrease in residual urine volume after treatment (103.72 ± 8.61 mL to 43.86 ± 4.92 mL, p < 0.001). At the 6-month follow-up, hematoxylin and eosin staining results demonstrated that Er:YAG laser treatment significantly facilitated an increase in the thickness of squamous epithelial cells. The efficacy of Er:YAG laser treatment for SUI was 77.78% (56/72). Conclusions: Several objective and subjective assessments confirmed the safety and efficacy of vaginal smooth mode Er:YAG laser treatment for mild-to-moderate SUI during the 6-month follow-up period. Nonablative Er:YAG laser in the smooth mode is a viable treatment option for SUI patients.

Innovative decision making tools using discrete mathematics for stress urinary incontinence treatment

In this study, we applied graph theory to clinical decision-making for Stress Urinary Incontinence (SUI) treatment. Utilizing discrete mathematics, we developed a system to visually understand the shortest path to the desired treatment outcomes by considering various patient variables. Focusing on women aged 35-50, we examined the effectiveness of Tension-free Vaginal Tape (TVT) surgery and Vaginal Erbium Laser (VEL) treatment for over 15 years. The TVT group consisted of 102 patients who underwent surgery using either the Advantage Fit mid-urethral sling system (Boston Scientific Co., MA, USA) or the GYNECARE TVT retropubic system (Ethicon Inc., NJ, USA). The VEL group included 113 patients treated with a non-ablative Erbium: YAG laser (FotonaSmooth™ XS; Fotona d.o.o., Ljubljana, Slovenia), and there were 112 patients in the control group. We constructed a network diagram analyzing the correlations between health, demographic factors, treatment methods, and patient outcomes. By calculating the shortest path using heuristic functions, we identified significant correlations and treatment effects. This approach supports patient decision making by choosing between TVT and VEL treatments based on individual objectives. Our findings provide new insights into SUI treatment, highlighting the value of a data-driven personalized approach for clinical decision-making. This interdisciplinary study bridges the gap between mathematics and medicine, demonstrating the importance of a data-centric approach in clinical decisions.

Shedding Light on Acne Scars: A Comprehensive Review of CO2 vs. Erbium-Doped Yttrium Aluminium Garnet (Er:YAG) Laser Therapy

Acne scars pose a significant cosmetic concern and can have a profound impact on individuals' self-esteem and quality of life. Laser therapy has emerged as a promising treatment modality for improving the appearance of acne scars by promoting collagen remodeling and tissue regeneration. This comprehensive review compares two commonly used laser modalities, CO2 and erbium-doped yttrium aluminum garnet (Er:YAG), focusing on their mechanisms of action, efficacy, safety profiles, and patient outcomes. While CO2 lasers offer deeper tissue penetration and the potential for more significant improvement in severe acne scars, Er:YAG lasers provide a gentler approach with a lower risk of post-inflammatory hyperpigmentation. Recommendations for clinical practice include tailoring treatment approaches to individual patient characteristics, educating patients about treatment expectations and post-treatment care, considering combination therapies for enhanced outcomes, and implementing regular follow-up care. Areas for further research include long-term outcome studies, investigation of laser therapy in ethnically diverse populations, exploration of combination therapies, and evaluation of emerging laser technologies. This review aims to provide clinicians and patients with valuable insights to inform treatment decisions and optimize outcomes in managing acne scars.

Current Treatment of Stress Urinary Incontinence by Bulking Agents and Laser Therapy-An Update

Stress urinary incontinence (SUI) affects around 20% of women. In addition to the established suburethral sling insertion, two less invasive approaches are of interest today: urethral bulking agents and vaginal laser therapy. This review discusses articles through December 2023 identified by a PubMed literature search using the keywords "incontinence" and "bulking" or "laser". Although the two approaches are less effective than sling insertions, there are specific conditions in which one or the other technique is more advantageous. Injecting bulking agents into the urethra only takes some minutes and works without general anesthesia. The method is particularly suited for elderly, frail, or obese patients with multiple comorbidities, but is also applicable for all patients and in combination with other therapies. Generally, the safety profile is good but differs between bulking materials. Two laser types-the Erbium:YAG laser with SMOOTH-mode and the fractional ablative CO2 laser-deliver heat into the tissue to induce tissue tightening and regeneration. Intravaginal laser therapy improves mild to moderate SUI, while studies describe how intraurethral laser therapy is also beneficial for severe SUI. Young women between childbirths, as well as postmenopausal women, may benefit from laser therapy. The method is safe, can be performed on an outpatient basis, and does not require any artificial material.

SUI in postmenopausal women: advantages of an intraurethral + intravaginal Er:YAG laser

OBJECTIVE

This study aimed to compare the efficacy of concomitant application of an intraurethral (IU) + intravaginal (IV) non-ablative Erbium (Er):YAG laser with IV application in improving the symptoms of stress urinary incontinence (SUI) in women.

METHODS

This observational retrospective cohort study included 122 patients with SUI, 60 women in the IU + IV laser arm and 62 in the IV laser arm. The primary outcome was the International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form score at entry and at 3, 6 and 12 months from baseline.

RESULTS

Demographic characteristics were comparable in both arms. Significant improvement in SUI symptoms was seen 3 months after the intervention and was sustained until the end of month 12 in both arms. The women who had severe SUI symptoms initially showed greater improvement. A higher number of women who initially had mild to moderate SUI symptoms were dry after treatment. Patients treated with IU + IV Er:YAG laser showed significant improvement in SUI symptoms compared to IV laser only, especially at postmenopausal state (p = 0.003).

CONCLUSIONS

The Er:YAG laser appears to be an efficient treatment method for SUI. Concomitant application of an IU + IV Er:YAG laser is more effective in relieving SUI symptoms at postmenopausal state.

Applicability of vaginal energy-based devices in urogynecology: evidence and controversy

OBJECTIVE

This study aimed to analyze the evidence and controversies about the use of vaginal energy-based devices (laser and radiofrequency) for treatment of genitourinary syndrome of menopause, recurrent urinary tract infection, urinary incontinence, and genital prolapse through a literature review.

METHODS

A search of literature databases (PubMed, Medline) was performed for publications in December 2022. Keywords included genitourinary syndrome of menopause, vaginal laxity, vaginal/vulvovaginal atrophy, urinary tract infection, urgency incontinence, frequency, urgency, stress urinary incontinence, genital prolapses AND energy-based devices, AND vaginal laser, AND vaginal radiofrequency, AND CO2 laser, AND Er:YAG laser. Publications in English from the last 7 years were reviewed and selected by the authors.

RESULTS

The literature regarding vaginal energy-based devices in the treatment of urogynecological conditions is primarily limited to prospective case series with small numbers and short-term follow-up. Most of these studies showed favorable results, improvement of symptoms with low risk, or no mention of serious adverse events. Consensus statement documents from major medical societies suggest caution in recommending these therapies in clinical practice until more relevant data from well-designed studies become available.

CONCLUSION

The potential of the vaginal laser and radiofrequency as a therapeutic arsenal for the evaluated urogynecological conditions is great, but qualified research must be done to prove their efficacy and long-term safety, define application protocols, and recommend the use of these technologies in clinical practice.

Analysis of Predictive Factors for Return to Sports in Female Athletes With Stress Urinary Incontinence

Introduction This study aimed to identify predictive factors for successful return to sports among elite female athletes (EFAs) experiencing stress urinary incontinence (SUI). We used machine learning to analyze these predictors. Methods This study was conducted at Yokosuka Urogynecology and Urology Clinic, located in Yokosuka City, Kanagawa, Japan. A total of 153 EFAs with postpartum SUI were included in this retrospective cohort study. Information regarding the frequency of pelvic floor muscle training (PFMT), treatment approaches, rates of return to sports after one year, and one-hour pad test (1HrPadtest) at three months were collected. Results At three months, 26.8% of the EFAs improved in SUI; after one year, 28.1% returned to their respective sports successfully. The equation for predicting return to sports (logit(p)) involved several factors: (a) serum total testosterone, (b) PFMT frequency per week, (c) 1HrPadtest at three months, and (d) vaginal erbium-doped yttrium aluminum garnet laser (VEL) + urethral EL (UEL) treatment. The equation was as follows: -126 - 0.07276a + 25.98b - 1.947c - 25.32d, with a logit(p) cutoff point at 0.5. The optimal cutoff values and the four influential factors were determined through a receiver operating characteristic (ROC) analysis and the random forest model, respectively. Conclusions For EFAs with severe SUI to successfully return to their sports activities, the PFMT frequency was paramount. Patients who exhibited unsatisfactory results in the 1HrPadtest at the three-month mark benefited from the VEL+UEL treatment. Serum total testosterone proved to be an effective discerning criterion.

Effect evaluation and influencing factor analysis of vaginal carbon dioxide laser in the treatment of stress urinary incontinence

To evaluate the clinical efficacy of carbon dioxide laser in the treatment of female stress urinary incontinence and analyze the influencing factors. A total of 46 patients with stress urinary incontinence treated in the Affiliated Hospital of Nantong University from March 2021 to August 2022 were included through strict inclusion criteria and exclusion criteria. All patients were treated with transvaginal carbon dioxide laser therapy, and Patient Global Impression of Change (PGI-C) was used to evaluate patients' subjective satisfaction after treatment. The efficacy was evaluated by patient's subjective assessment of leakage, IngelmanSundberg scale, 1-h urine pad test, and international consultation on incontinence questionnaire short form (ICI-Q-SF) before and after treatment, and the adverse reactions after treatment were recorded. The treatment effect was divided into "significant effect group" and "no significant effect group" by subjective satisfaction and post-treatment-related scale evaluation. After laser treatment, patients' subjective symptom improved, the volume of 1-h urine pad test was reduced, and the ICI-Q-SF score was decreased, and the differences were statistically significant (P < 0.05). There was no significant difference in IngelmanSundberg scale before and after treatment (P = 1.00). Multivariate logistic regression analysis showed that pad test volume was significantly correlated with treatment effect (P = 0.007). Transvaginal carbon dioxide laser is a safe and effective method for the treatment of mild to moderate stress urinary incontinence in females. The less severe the urinary leakage, the better the treatment effect.

[Vaginal laser therapy-myths and facts]

The current guideline "Female Urinary Incontinence" of the working group of scientific medical professional associations (AWMF) comprises a recommendation about the optional use of vaginal laser therapy in patients with mild to moderate stress urinary incontinence (SUI). Since to date there is no corresponding recommendation within the European Association of Urology (EAU) guidelines, the scientific evidence of the AWMF recommendation is evaluated. On the basis of limited data, both available laser systems (Erbium:YAG and CO₂) seem to work equivalently in patients with mild SUI. The problematic comparability of studies with different definitions of incontinence, severity classifications, outcome parameters, and consideration of diverse etiological aspects is addressed. After thorough consideration of the available prognosticator research, a profile of an ideal laser candidate is developed for proper patient selection. This profile includes younger age, normal body mass index, sufficient estrogenization status, pure stress urinary incontinence due to urethral hypermobility, and urine loss of < 8 g during a 1 h pad test.

The evidence behind the use of LASER for genitourinary syndrome of menopause, vulvovaginal atrophy, urinary incontinence and lichen sclerosus: A state-of-the-art review

In recent years, LASER has been introduced as a minimally invasive treatment for a broad range of vaginal and vulvar symptoms and diseases. However, the efficacy and safety of vaginal and vulvar LASER has continuously been questioned. The aim of this study is to create an overview of the current literature and discuss the controversies within the use of LASER for genitourinary syndrome of menopause, vulvovaginal atrophy, urinary incontinence and lichen sclerosus. A search string was built in PubMed. The search was commenced on August 25, 2021 and closed on October 27, 2021. Two authors screened the studies in Covidence for inclusion according to the eligibility criteria in the protocol. The data were extracted from the studies and are reported in both text and tables. This review included 114 papers, of which 15 were randomized controlled trials (RCTs). The effect of LASER as a vaginal treatment was investigated for genitourinary syndrome of menopause in 36 studies (six RCTs), vulvovaginal atrophy in 34 studies (four RCTs) and urinary incontinence in 30 studies (two RCTs). Ten studies (three RCTs) investigated the effect of vulvar treatment for lichen sclerosus. Half of the included RCTs, irrespective of indication, did not find a significant difference in improvement in women treated with vaginal CO₂ or Er:YAG LASER compared with their respective controls. However, most non-comparative studies reported significant improvement after exposure to vaginal or vulvar LASER across all indications. Included studies generally had a short follow-up period and only a single RCT followed their participants for more than 6 months post treatment. Adverse events were reported as mild and transient and 99 studies including 51 094 patients provided information of no serious adverse events. In conclusion, this review found that the effect of vaginal and vulvar LASER decreases with higher study quality where potential biases have been eliminated. We therefore stress that all patients who are treated with vaginal or vulvar LASER should be carefully monitored and that LASER for those indications as a treatment should be kept on a research level until further high-quality evidence is available.

Vaginal Laser Therapy for Female Stress Urinary Incontinence: New Solutions for a Well-Known Issue-A Concise Review

Background and Objectives: Insufficient connective urethra and bladder support related to childbirth and menopausal estrogen decrease leads to stress urinary incontinence (SUI). The aim of this review is to narratively report the efficacy and safety of new mini-invasive solutions for SUI treatment as laser energy devices, in particular, the microablative fractional carbon dioxide laser and the non-ablative Erbium-YAG laser. Materials and Methods: For this narrative review, a search of literature from PubMed and EMBASE was performed to evaluate the relevant studies and was limited to English language articles, published from January 2015 to February 2022. Results: A significant subjective improvement, assessed by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI-SF) was reported at the 6-month follow up, with a cure rate ranged from 21% to 38%. A reduction of effect was evidenced between 6 and 24-36 months. Additionally, the 1-h pad weight test evidence a significant objective improvement at the 2-6-month follow up. Conclusions: SUI after vaginal laser therapy resulted statistically improved in almost all studies at short-term follow up, resulting a safe and feasible option in mild SUI. However, cure rates were low, longer-term data actually lacks and the high heterogeneity of methods limits the general recommendations. Larger RCTs evaluating long-term effects are required.

Comparison of urethral sling surgery and non-ablative vaginal Erbium:YAG laser treatment in 327 patients with stress urinary incontinence: a case-matching analysis

Stress urinary incontinence (SUI) occurs when abdominal pressure, such as from coughing or sneezing, causes urine leakage. We retrospectively compared tension-free vaginal tape (TVT) and non-ablative vaginal Erbium:YAG laser treatment (VEL) by propensity score (PS) analysis in women with SUI. No PS analysis studies have investigated urethral sling surgery using polypropylene TVT and VEL for SUI. Data from patients aged 35-50 years who were treated for SUI and registered at several institutions were selected. Patients with medical records covering 1 year for the 1-h pad test, who completed the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and the Overactive Bladder Symptom Score (OABSS), were included. We analyzed 102, 113, and 112 patients in the TVT, VEL, and control groups, respectively. Compared with the control group, the TVT and VEL groups exhibited significant improvement in the 1-h pad test and ICIQ-SF. In the PS analysis, the TVT and VEL groups similarly improved in the 1-h pad test and ICIQ-SF. As for the OABSS, the VEL group showed significantly greater improvement than the TVT group. In the odds ratio analysis for the 1-h pad test, no differences in any of the parameters were observed between TVT and VEL. VEL may be considered an alternative to TVT for SUI treatment.

Pixel-CO2 laser for the treatment of stress urinary incontinence

Abstract

The aim of this study was to assess the safety and efficacy of a minimally invasive pixel-CO₂ laser procedure for the treatment of stress urinary incontinence (SUI). This was a prospective, open-label study with a cohort of 59 women. Patients were treated intravaginally with a fractional/pixel CO₂ laser every 4–6 weeks for a total of three treatments and assessed at 3, 6, and 12 months. Evaluation tools included a Sandvik severity score based on a validated questionnaire, 1-h pad test, vaginal health index score (VHIS), validated female sexual function index (FSFI), patient’s impression of disease severity (PGI-S), global impression of improvement (PGI-I), and the short-term pelvic floor impact questionnaire (PFIQ-7) to assess improvements in quality of life. Reduction in SUI severity was noticed throughout the duration of the study, as compared to the baseline in which 2% of the patients were defined as “slight,” 73% “moderate,” and 25% “severe.” Gradual improvement of symptoms resulted in redistribution of severity score and the best outcome observed between 3 and 6 months. Sanitary pad weight declined from an average of 35.45 g per day at baseline to 12.47 g at the 3rd treatment, and increased to 23.06 g at 12 months. Vaginal acidity changes showed a similar pattern. No serious adverse events were reported. Pixel-CO₂ laser is safe and effective for treating SUI. Additional maintenance treatments should be considered during the 6–12-month post-treatment period in order to maintain the beneficial effects.

Brief summary

Pixel-CO₂ laser is a safe and effective treatment for SUI. Maintenance treatments should be considered at 6–12 months.

The use of vaginal lasers in the treatment of urinary incontinence and overactive bladder, systematic review

OBJECTIVES

To evaluate the available literature to assess the safety, efficacy, and outcomes of lasers in the treatment of female stress urinary incontinence (SUI) and overactive bladder (OAB).

METHODS

Pubmed search was conducted up to May 2020, including observational and investigational human studies that documented the effects on laser treatment in SUI and OAB.

RESULTS

A total of 27 studies, recording subjective or objective measures in SUI or OAB were included. Lasers used included Er:YAG and Fractional CO2 lasers. The overall quality of studies was poor, and 23/27 studies were case series (LOE:4). Er:YAG laser showed a modest reduction in mild SUI cases, with benefits lasting a maximum of 13-16 months. Er:YAG laser for OAB showed conflicting results, with a trend to improve OAB symptoms for up to 12 months. Fractional CO2 laser showed an improvement of mild SUI in few studies; however, no long-term data are available. For OAB symptoms, studies showed minimal improvement that was evaluated in short term studies. When reported, adverse events were insignificant, however, they were not reported systematically. Several limitations have been noticed in the current literature of vaginal lasers, including large variation in laser settings and protocols, short term follow up, lack of urodynamic evaluation, and appropriate objective measures.

CONCLUSION

Based on the available literature, lasers cannot be recommended as a treatment option at this time. Future better-quality studies are needed to document the exact mechanism of action, longevity, safety and its eventual place into the current treatment algorithms of SUI and OAB.

Er:YAG laser in hysterectomized women with stress urinary incontinence: a VELA retrospective cohort, non-inferiority study

Objective: To test whether the erbium-doped yttrium aluminum garnet (Er:YAG) SMOOTH^® laser treatment efficacy on stress urinary incontinence (SUI) in hysterectomized patients is non-inferior to its efficacy in non-hysterectomized patients.Methods: In this real-world, retrospective cohort study performed in Turkey, Croatia and Italy, we enrolled a consecutive sample of 35 hysterectomized and 34 non-hysterectomized patients with SUI. We used the Er:YAG SMOOTH^® laser (Fotona, Slovenia) with a wave length of 2940 nm. The primary outcome was median reduction of SUI symptoms measured by the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short-Form (ICIQ-SF) with the non-inferiority margin defined as the minimum clinically important difference of ICIQ-SF (δ < 2.52 points).Results: In hysterectomized patients, the ICIQ-SF was reduced by 5 points (95% confidence interval 3-8; p < 0.001), a reduction of 45% (95% confidence interval 36-67%). After adjustment for baseline ICIQ-SF and five covariates, the reduction of symptoms in the hysterectomized group was not inferior to the reduction in the non-hysterectomized group.Conclusion: The Er:YAG SMOOTH^® laser treatment seems to improve the symptoms of SUI in hysterectomized women not clinically relevantly less than in non-hysterectomized women. It seems that the beneficial effect of Er:YAG SMOOTH^® laser treatment for SUI in hysterectomized women is time-limited.

Female urine incontinence: vaginal erbium laser (VEL) effectiveness and safety

Urinary incontinence is a common health problem that impacts the quality of life of women at different ages. Its physiopathology is not unequivocal, and it is necessary to consider the stress urinary incontinence (SUI), the overactive bladder syndrome and the mixed incontinence (MUI). According to the type of incontinence, its impact on the quality of life and age of the patients, therapeutic strategies are currently summarized in physiotherapy, surgery and drug treatments. We already know the benefit/risk ratio of each of these strategies. Our objective is to evaluate the potential effectiveness and safety of the VEL, an innovative vaginal laser technique (VEL - Vaginal Erbium Laser, erbium yttrium-aluminum-garnet -Er: YAG) a non-invasive laser proposed as a treatment for SUI, overactive bladder syndrome and MUI. The mechanisms of action of lasers are discussed in general and those of VEL in particular with the description of the Smooth® mode. To do this, we have collected the 21 published studies including the first randomized vs. placebo and two pilot studies of intra-urethral VEL. In conclusion: VEL procedures already have their place between the rehabilitation of the perineal floor and surgery. Further properly sized, randomized studies are needed to evaluate the laser treatments in comparison with other therapies, as well as to assess the duration of the therapeutic effects and the safety of repeated applications.

The first major complication due to laser treatment for stress urinary incontinence: a short report

AIM

Stress urinary incontinence (SUI) is a common benign disease causing a markedly negative impact on quality of life. Vaginal laser is a minimally invasive treatment and no major complications of this technique have been published to date. The purpose of the article is to present the first major adverse event related to this treatment.

MATERIALS AND METHODS

We present the case of a 48-year-old woman with an important complication after vaginal laser for SUI.

RESULTS

The patient presented a transverse vaginal septum and shortening of vaginal length after two sessions of vaginal erbium:yttrium aluminum garnet laser treatment. She required two surgical interventions, local injections, and pelvic floor physiotherapy, although currently the patient has not experienced complete resolution of symptoms.

DISCUSSION AND CONCLUSIONS

Vaginal laser use can lead to serious adverse events. Selection of patients and treatment must be carried out with caution.

Pixel CO2 Laser for the Treatment of Stress Urinary Incontinence: A Prospective Observational Multicenter Study

BACKGROUND AND OBJECTIVES

Energy-based treatments have been found to be a promising treatment modality for improving stress urinary incontinence (SUI) symptoms. This prospective two-center study was designed to evaluate the efficacy of fractional-pixel CO₂ laser for the treatment of SUI.

STUDY DESIGN/MATERIALS AND METHODS

Eighty-five women with SUI symptoms as per the cough stress test and validated International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), were treated intravaginally with Pixel-CO₂ laser. Two treatment sessions were performed with a 1-month interval. Safety and treatment tolerance were assessed by the visual analog scale (VAS) immediately and at 1 week after each laser treatment. Associations of age and body mass index (BMI) with the ICIQ-UI-SF score were statistically assessed by the Jonckheere-Terpstra test.

RESULTS

The ICIQ-UI-SF score was 12.0 at baseline, 7.0, after the first treatment, and 3.5 after the second treatment (P = 0.001). For women with BMI (25.0-29.9), the ICIQ-UI-SF score was 9.0 at the baseline, 6.0 after 1 month, and 5.0 at the 6 months follow-up visit (P = 0.04). For women with BMI ≥ 30.0, the ICIQ-UI-SF score was reduced from 14.0 to 8.0 1 month after the baseline and 5.0 at the 6-month follow-up visit (P = 0.001). SUI severity evaluation at baseline showed that 27.1% of women had mild, 24.7% had moderate, 45.9% had severe, and 2.4% had very severe SUI symptoms. SUI severity scores were significantly reduced, with 45.8% of women with no SUI symptoms, 18.8% with mild, 20.8% with moderate, and 14.6% with severe SUI symptoms at the 6-month follow-up. The patient's evaluation of VAS after the first treatment was 1.0-1.5 (0-10) and 0.0 1 week after the second treatment.

CONCLUSION

Fractional-pixel CO₂ laser is safe and effective for treating SUI. No adverse event or significant pain was reported during or after the procedure. Its safety and efficacy are clearly demonstrated. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Er:YAG laser treatment of urinary incontinence after failed TOT/TVT procedures

OBJECTIVE

To determine if the Er:YAG laser can improve the symptoms of SUI patients after previously failed TOT/TVT procedures.

STUDY DESIGN

This retrospective study includes the data of patients who were recruited from two different out-patient clinics of Obstetrics and Gynecology Department. 25 women with persistent SUI after failed TOT/TVT operations and 25 women who previously did not receive either any type of surgical treatment procedure or non-invasive treatment modalities for SUI. Er:YAG laser with 2940 nm was used in the treatment procedure for SUI setting. The patients were evaluated on the basis of ICIQ-SF before and after the procedure. The severity of SUI symptoms was graded. According to the differences in the ICIQ-SF between before and after the procedure, the percentage of improvement was graded as good responders (≥50 %) or poor responders (<50 %).The duration of the treatment effect was evaluated in follow-ups with relation to maximum improvement time (MIT) and total improvement time (TIT).

RESULTS

The SUI patients who previously had failed TOT/TVT operations, had significantly higher initial ICIQ-SF score (p = 0.013). Non-ablative Er:YAG laser treatment significantly and similarly improved the severity of SUI symptoms in both groups (p = 0.000 for failed TOT/TVT group and p = 0.001 for non-TOT/TVT group, respectively). The women who were good responders, were younger (p = 0.012) and had less number of years in menopause (p = 0.011). The effect of Er:YAG laser treatment lasted longer among the SUI women in the good responders group (p = 0.000 for MIT and p = 0.000 for TIT, respectively).

CONCLUSIONS

Non-ablative Er:YAG smooth mode laser is an alternative choice of treatment for the SUI patients who previously had failed TOT/TVT procedures. Its effect lasts longer especially in younger and early postmenopausal women.
