Vaginal Fractional Carbon Dioxide Laser Treatment and Changes in Vaginal Biomechanical Parameters.

BACKGROUND AND OBJECTIVES: Vaginal fractional carbon dioxide (CO2 ) laser treatment has emerged in the past two decades as a non-surgical option for vaginal tightening. Mounting evidence supports the effectiveness and safety of this treatment for female sexual dysfunction. A newly developed vaginal tactile imaging (VTI) technique accurately evaluates the biomechanical parameters of the female pelvic floor and vagina, including tissue elasticity, pelvic support, and pelvic muscle function in high definition. In the current study, we evaluated changes in objective biomechanical parameters using VTI, following vaginal CO2 laser treatment for vaginal tightening and sexual dysfunction. STUDY DESIGN/MATERIALS AND METHODS: We conducted a prospective cohort between June 2018 and January 2020. Inclusion criteria were vaginal looseness, decreased local sensation during sexual intercourse, and sexual dysfunction. All the participants were treated with a vaginal carbon dioxide laser. They underwent a gynecological evaluation based on the Vaginal Health Index (VHI) and sexual function assessment according to the Female Sexual Function Index (FSFI). Vaginal biomechanical parameters were assessed by VTI. Initial evaluations were performed at the pre-treatment consult visit, 1 week prior to the first treatment and at a 6-month post-treatment follow-up visit. RESULTS: Twenty-five women were included in the final analysis. Compared with baseline, the post-treatment mean scores for vaginal elasticity and tightening were higher (54.8 ± 5.2 vs. 41.5 ± 6.3, P = 0.0027 and 1.97 ± 0.25 vs. 1.32 ± 0.31, P = 0.0014, respectively). Post-treatment increases were demonstrated in pelvic muscle contraction strength (25.9 ± 3.5 vs. 16.5 ± 4.2, P = 0.0011) and in reflex pelvic muscle contraction (2.93 ± 0.44 vs. 2.12 ± 0.47, P = 0.0022); the mean FSFI and VHI scores were higher following treatment (28.47 ± 1.73 vs. 21.12 ± 1.58, P = 0.036 and 19.15 ± 1.27 vs. 11.6 ± 0.97, P = 0.0032). CONCLUSIONS: The quantification of vaginal biomechanical parameters using VTI technology offers objective evidence of the beneficial effect of vaginal CO2 laser treatment. Lasers Surg.

The impact of vaginal hysterectomy and uterosacral ligament suspension on vaginal elasticity and sexual function.

OBJECTIVE: Hysterectomy for benign indications has profound effects on both anatomical and physiological pelvic floor and vaginal properties. Vaginal tactile imaging (VTI) enables the quantification of pelvic floor and vaginal biomechanical properties; this enables objective evaluation of various pelvic floor functions. The purposes of this study were to evaluate via VTI, the changes in vaginal elasticity, mobility and strength, before and after hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) and high utero-sacral ligament suspension (USLS); and to assess associations with sexual function. The objective of the current study was to evaluate the effect of these procedures on vaginal elasticity and sexual function. STUDY DESIGN: This prospective cohort study included women who underwent hysterectomy by vNOTES and USLS for the treatment of pelvic organ prolapse (POP). All the women underwent both pre- and postoperative VTI and sexual function evaluation. Vaginal elasticity and wall mobility, and the contraction strength and tone of levator muscles, were measured prior to and 6 months following surgery using VTI. RESULTS: A total of 23 women, mean age 56.5 years, with stage 3-4 POP participated. Vaginal elasticity increased from 27.3 ± 8.8 to 34.8 ± 12 (P < 0.05) and Female Sexual Function Index (FSFI) scores increased from 22.17 ± 1.62 to 28.66 ± 1.51 (P < 0.05). No correlation was observed between these results. A statistically significant decrease in the mobility of the anterior vaginal wall was demonstrated, from 7.98 ± 10.6 to 0.83 ± 7.5 (P < 0.0001). CONCLUSIONS: VTI showed improvements in vaginal elasticity, mobility and FSFI scores following hysterectomy and POP repair performed by vNOTES.

The Efficacy and Safety of CO2 Laser Treatment for Sexual Function and Vaginal Laxity Improvement in Pre-Menopausal Women.

BACKGROUND AND OBJECTIVES: Vaginal laxity lacks standardized diagnosis and severity criteria. It is considered as a subjective complaint that reflects decreased sexual satisfaction due to vaginal loosening. Treatment modalities have included physiotherapy and plastic surgery. Recently, laser treatments have also gained popularity as a means of relieving gynecological complaints such as pelvic organ prolapse, stress urinary incontinence, and genitourinary syndrome of menopause. The aim of the current study was to evaluate the efficacy of CO2 laser treatment in women for whom a decrease in sexual sensation during intercourse and vaginal loosening were their primary complaints. STUDY DESIGN/MATERIALS AND METHODS: For this prospective study, women with reported vaginal laxity and decreased sensation during intercourse were recruited from the Sexual Dysfunction Clinic in our health care campus. Each participant received three outpatient treatments with laser therapy, according to the same protocol. Treatment efficacy was assessed by changes in the Vaginal Health Index (VHI) and Female Sexual Function Index (FSFI). RESULTS: Overall, 84 pre-menopause women, with a mean age of 47.7 years, were included in the study. Mean VHI and FSFI were increased significantly at 3 months post-treatment and decreased again at 6 months post-treatment: 11.8 ± 1.6, 13.5 ± 1.1, and 11.8 ± 1.2, respectively, P = 0.013; and 21.3 ± 1.7, 29.9 ± 1.6, and 22.5 ± 1.8, respectively, P = 0.022. The rate of sexual intercourse doubled during the period of maximal treatment effect (P < 0.0001). CONCLUSIONS: CO2 laser treatment has both a statistically and clinically significant effect on participants' complaints and sex-life, which wanes by 6 months post-treatment. Laser therapy seems to be safe in the short term, with no serious adverse events reported in the current study. Further studies are warranted to determine the long-term safety and the efficacy of maintenance laser treatments. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Low-Intensity Shock Wave Therapy in Sexual Medicine-Clinical Recommendations from the European Society of Sexual Medicine (ESSM).

INTRODUCTION: Low-intensity shockwave therapy (LISWT) has been investigated for the treatment of uroandrological disorders including erectile dysfunction (ED), Peyronie's disease (PD) and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) with controversial findings. AIM: To review the evidence on LISWT for ED, PD, and CP/CPPS and provide clinical recommendations on behalf of the European Society of Sexual Medicine. METHODS: Medline and Embase databases were searched for randomized clinical trials (RCTs), meta-analyses and open-label prospective or retrospective studies investigating the effect of LISWT on ED, PD, or CP/CPPS. OUTCOMES: The panel provided statements on clinically relevant questions concerning LISWT: (i) treatment efficacy, (ii) treatment protocol, (iii) clinical indications, and (iv) safety. The level of evidence was provided according to the Oxford 2011 criteria and graded using the Oxford Centre for Evidence-Based Medicine recommendations. RESULTS: 11 RCTs and 5 meta-analyses investigated LISWT for ED. RCTs provided controversial results on the efficacy of LISWT and were affected by high heterogeneity and the small number of patients included. Pooled-data analysis showed an overall positive effect in terms of erectile function improvement but reported small estimates and included a largely heterogeneous cohort of patients. 4 RCTs and 1 meta-analysis assessed LISWT for PD. All trials showed positive findings in terms of pain relief but no effect on penile curvature and plaque size. Inclusion criteria vary widely among studies, and further investigation is needed. 5 RCTs investigated LISWT for CP/CPPS. Data showed a possible effect on pain relief, although there is no evidence supporting that pain relief was maintained or any improvement in pain over time. CLINICAL IMPLICATIONS: LISWT needs to be further investigated in the context of sexual medicine and is almost but not yet ready for clinical practice. STRENGTHS AND LIMITATIONS: All studies have been evaluated by a panel of experts providing recommendations for clinical practice. CONCLUSIONS: LISWT is a safe and well-tolerated procedure but its efficacy for the treatment of ED is doubtful and deserves more investigation. Patients reporting pain associated with PD may benefit from LISWT, although no effect is expected on disease progression. LISWT is not a primary treatment for CP/CPPS, but it may be considered as an option to relieve pain. Capogrosso P, Frey A, Jensen CFS, et al.

Effect of Midurethral Sling Surgery on Vaginal Sensation.

INTRODUCTION: Previous studies have reported changes in the sensory functioning of the vagina in women with pelvic floor disorder. AIM: To evaluate vaginal and clitoral sensation before and after surgery with trans-obturator tape (TVT-O, Ethicon Johnson & Johnson). METHODS: Quantitative sensory thresholds for warm, cold, and vibratory sensations were measured at the vagina and clitoris 1 day before and 12 ± 4 months after surgery. MAIN OUTCOME MEASURES: Differences in thresholds to warm, cold, and vibratory sensations at a predetermined anatomic area of the genital region. RESULTS: Twenty-two women were admitted for midurethral sling surgery, and four were lost to follow-up. For the remaining 18 (mean age = 52 years, range = 37-65), we found a significant sensory decrease at the clitoral region to cold, warm, and vibratory stimuli after surgery. In contrast, in the anterior vaginal wall, there was a significant decrease only to warm stimuli after surgery. CONCLUSION: TVT-O can cause sensory loss in the clitoral and anterior vaginal wall region that can be measured and quantified. The effect of such sensory loss on sexual function and quality of sexual life needs further investigation.

The effect of pelvic organ prolapse repair on vaginal sensation.

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate vaginal and clitoral sensation before and after robotic sacrocolpopexy for the repair of pelvic organ prolapse. METHODS: Twenty-two women, mean age 63 years (range 41-77), were admitted for robotic sacrocolpopexy repair of pelvic organ prolapse; 4 were lost to follow-up. Quantitative sensory thresholds for warm, cold, and vibratory sensations were measured at the vagina (anterior and posterior areas) and clitoris 1 day before and a mean of 12 ± 4 months following surgery. Student's paired t test was used to compare sensory thresholds before and after surgery. RESULTS: For the 18 women who completed follow-up, sensitivity was significantly higher after surgery (sensory threshold decreased) at the clitoral and vaginal regions, to cold and warm stimuli. In contrast, the vaginal and clitoral vibratory sensory thresholds did not change significantly following surgery. CONCLUSION: The repair of pelvic organ prolapse by robotic sacrocolpopexy could potentially play a role in restoring clitoral and vaginal wall sensation. The effects of these sensory changes on sexual function and the quality of sexual life need further investigation.

[Position statement for the diagnosis and treatment of men with benign prostate enlargement and lower urinary tract symptoms].

Benign prostate enlargement causing lower urinary symptoms is a common progressive phenomenon in adult men. Lower urinary tract symptoms may emerge during the storage, voiding, and post micturition phases, harm quality of life and may be caused by a variety of factors. The purpose of evaluation is to identify benign prostate enlargement and factors other than enlarged prostate as the cause of symptoms, and recognize the risk factors for progression of the condition. The goal of treatment is to alleviate symptoms and improve quality of life, and to prevent deterioration of symptoms and development of complications. Medical therapy is the basic approach, whereas surgery and minimally invasive procedures are reserved for patients not interested in medical therapy or for those in whom symptoms were not alleviated by means of medical therapy. In the present position statement, we present the approach to the evaluation and treatment of lower urinary tract symptoms in men with benign prostate enlargement.

Does the G-spot exist? A review of the current literature.

In 1950, Gräfenberg described a distinct erotogenic zone on the anterior wall of the vagina, which was referred to as the Gräfenberg spot (G-spot) by Addiego, Whipple (a nurse) et al. in 1981. As a result, the G-spot has become a central topic of popular speculation and a basis of a huge business surrounding it. In our opinion, these sexologists have made a hotchpotch of Gräfenberg's thoughts and ideas that were set forth and expounded in his 1950 article: the intraurethral glands are not the corpus spongiosum of the female urethra, and Gräfenberg did not report an orgasm of the intraurethral glands. G-spot amplification is a cosmetic surgery procedure for temporarily increasing the size and sensitivity of the G-spot in which a dermal filler or a collagen-like material is injected into the bladder-vaginal septum. All published scientific data point to the fact that the G-spot does not exist, and the supposed G-spot should not be identified with Gräfenberg's name. Moreover, G-spot amplification is not medically indicated and is an unnecessary and inefficacious medical procedure.

The status of penile enhancement procedures.

PURPOSE OF REVIEW: Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). This fact by itself leads to controversy regarding the true indications for penile enhancement procedures in men without micropenis. RECENT LITERATURE: One of the typical aspects of penile enhancement is the lack of true methodological evaluation of the more commonly performed procedures. Even recently, only few solid scientific studies are available which can shed some light on results and outcome of these controversial procedures. SUMMARY: Although some additional data has emerged during the past year, there is still no consensus in regard to indications and surgical techniques used for penile augmentation or penile girth enhancement. There is further need for more studies to provide a better overview of the value and worthiness of these procedures.

A critical analysis of penile enhancement procedures for patients with normal penile size: surgical techniques, success, and complications.

CONTEXT: Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). OBJECTIVES: The aim of this review is to describe the various reported techniques and to provide the available scientific data on the success and complication rates of penile enhancement procedures. EVIDENCE ACQUISITION: We performed an extensive systematic review based on a search of the MEDLINE database for articles published between 1965 and 2008. The following key words were used: penis, enhancement, enlargement, phalloplasty, reconstruction, girth, lengthening, and augmentation. Only English-language articles that were related to penile surgery and dysmorphobia were sought. We excluded articles in which fewer than five cases were described and articles in which the type of surgical treatment and the outcome were not clear. Of the 176 papers found, 34 were selected and critically analyzed. EVIDENCE SYNTHESIS: We found only a small number of well-designed and comprehensive studies, and most of the published articles reported data that were obtained from small cohorts of patients. The more recently published studies presented better methodologies and descriptions of the surgical techniques than did the older publications. In general, penile enhancement surgery can cause a 1-2-cm increase in penile length and a 2.5-cm augmentation of penile girth. Unwanted outcomes and complications, namely penile deformity, paradoxical penile shortening, disagreeable scarring, granuloma formation, migration of injected material, and sexual dysfunction were reported frequently in these studies. Disappointing short- and long-term patient satisfaction rates following these procedures were also reported in most studies. CONCLUSIONS: To date, the use of cosmetic surgery to enlarge the penis remains highly controversial. There is a lack of any standardization of all described procedures. Indications and outcome measures are poorly defined, and the reported complications are unacceptably high. In our opinion, until new, reliable, and more objective and reproducible data are available, these procedures should be regarded as investigational and patients should be discouraged from undergoing these invasive treatments.

Validation of a real-time urodynamic measure of urinary sensation.

OBJECTIVE: The purpose of this study was to test the feasibility and validity of a continuous measurement of urinary sensation during cystometry. STUDY DESIGN: Subjects continuously recorded their level of urinary sensation during cystometry with the use of urodynamic diagnoses and responses to the Medical Epidemiologic and Social Aspects of Aging (MESA) and Urinary Distress Inventory (UDI) scales. Trends in urinary sensation recordings by increasing percentage of maximum cystometric capacity (MCC) were captured and compared with the use of growth curves. RESULTS: Fifty-one women participated: 18 patients had detrusor overactivity incontinence (DOI); 15 patients had urodynamic stress incontinence; 9 patients had mixed incontinence, and 9 patients did not demonstrate incontinence. In the volume range between 35% and 75% of MCC, the mean sensation level was higher in the DOI group than the other groups (P < .04). Urge sensation at 50% of MCC correlated with UDI and MESA urge subscales (rho = 0.34, p < .03 and rho = 0.39, p < .02). CONCLUSION: This study demonstrates that the Urgeometer measurement is feasible and correlates with urodynamic diagnosis and the severity and bother from urge incontinence.

Does hysterectomy affect genital sensation?

OBJECTIVES: To evaluate vaginal and clitoral sensation before and after hysterectomy and to assess pre- and post-surgery changes in sexual function. STUDY DESIGN: Quantitative sensory thresholds for warm, cold, and vibratory sensations were measured at the vagina and clitoris 1 day prior to and 3 months following surgery. A survey was performed 18 months following operation to evaluate long-term changes in sexual function. PARTICIPANTS: Twenty-seven women, aged 30-57 years, who were admitted for elective hysterectomy. MAIN OUTCOME MEASURES: Genital sensation and reported sexual function. RESULTS: There was significant deterioration in sensation to cold and warm stimuli at the anterior and posterior vaginal wall after surgery. Vaginal vibratory sensation thresholds tended to increase. Clitoral thermal and vibratory sensation thresholds remained unchanged before and after surgery. Of the 22 patients who participated in the follow-up survey, 17 did not report any decline in sexual function, while 4 patients reported deterioration in genital sensation and in sexual function. CONCLUSION: The results demonstrate quantifiable sensory loss in the vagina after hysterectomy, with preservation of clitoral sensation. Only a minority of patients reported a decline in their sexual function. These findings highlight the relative importance of clitoral as compared to vaginal sensation in sexual function.
