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

SUMMARY 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.

Testicular volume and Tanner stage: determinant factors for testicular torsion

ABSTRACT Objective To assess testicular volumes and sexual maturation in patients with testicular torsion. Methods A retrospective analysis of consecutively treated patients with testicular torsion between 2016 and 2018. Age, pubic hair staging (Tanner), and by ultrasonography, volume of the unaffected testis (in cubic centimeters) were evaluated either immediately before surgery or at the first postoperative visit. Patients with previous testicular disease, such as cryptorchidism, or with no records of testicular volume were excluded. The analysis included descriptive statistics and Bayesian regression. Results We treated 149 patients during the study period, and 141 (94.6%, median age 17.3 years) met the inclusion criteria. Median testicular volume was 13.0cm3 (interquartile range of 10.5-15.2), with similar right and left volumes (12.9cm3versus 13.3cm3; p=0.94). Sixty-five (46.1%) patients were Tanner stage IV, 17 (12.1%) stage III, and 59 (41.8%) stage V. Conclusion In this study, we were able to estimate volumes of testicular torsion, which aggregated around late puberty values (13.0cm3 for the whole dataset, 12.2cm3 for patients <25 years), suggesting that testicular hypermobility, due to congenital anatomical abnormalities, remains quiescent until the organ reaches a critical volume, after which torsion becomes possible. These findings provide a tentative explanation for the disease's age distribution.

Can Supervised Pelvic Floor Muscle Training Through Gametherapy Relieve Urinary Incontinence Symptoms in Climacteric Women? A Feasibility Study / O treinamento por meio de gameterapia pode aliviar os sintomas de incontinência urinária em mulheres climatéricas? Um estudo de viabilidade

Abstract Objective To investigate the feasibility of pelvic floor muscle training (PFMT) through gametherapy for relieving urinary symptoms of climacteric women with stress ormixed urinary incontinence (UI). Methods Randomized clinical trial, divided into two groups: Gametherapy (G_Game) and Control (G_Control). Both groups received recommendations about unsupervised PFMT, and G_Game also received supervised PFMT through gametherapy. After 5 consecutive weeks, the feasibility was investigated considering participant adherence, urinary symptoms (evaluated by the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form [ICIQ-UI-SF] questionnaire), and pelvic floor function (PERFECT Scheme: power, endurance, repetition and fast). The Fisher exact, Kruskal-Wallis, Wilcoxon sign paired, and Mann-Whitney U tests were used by intention-to-treat analysis, using STATA 15.1 (StataCorp, College Station, TX, USA) software. Results The present study included 20 women per group and observed a higher adherence in G_Game. In the intragroup analysis, a decrease in the ICIQ-UI-SF score was observed in both groups (14.0 to 10.0; 13.5 to 0), associated with increased endurance (2.5 to 3.5; 2.5 to 4.0) in G_Control and G_Game, respectively. Moreover, there was a concomitant increase in pelvic floor muscles (PFMs) power (2.0 to 3.0), repetition (3.0 to 5.0), and fast (10.0 to 10.0) in G_Game. In the intergroup analysis, a reduction of UI was observed (p<0.001; r=0.8), as well an increase in PFM power (p=0.027, r=0.2) and endurance (p=0.033; r=0.3) in G_Game. Conclusion The feasibility of supervised PFMT through gametherapy was identified by observing participant adherence, relief of urinary symptoms, and improvement in PFM function.

Can platelet-rich plasma coating improve polypropylene mesh integration? An immunohistochemical analysis in rabbits

ABSTRACT Purpose: Despite high success rates in the treatment of urinary incontinence, complications related to the use of polypropylene (PP) meshes are still a concern, especially in vaginal prolapses surgeries. The objective of this study was to assess the effect of autologous platelet-rich plasma (PRP) coating on the integration of PP meshes implanted in the vaginal submucosa of rabbits. Materials and Methods: Thirty adult New Zealand rabbits were randomly divided into two groups (n=15): PP, implanted with conventional PP meshes; and PRP, implanted with autologous PRP coated PP meshes. Animals in both groups (n=5) were euthanized at 7, 30 and 90 days postoperatively, the vaginas extracted and sent to immunohistochemical analysis for the assessment of the pro-inflammatory agent TNF-α, anti-inflammatory agents TGF-β and IL-13, collagen metabolism marker MMP-2, and angiogenesis marker CD-31. AxioVision™ image analysis was used for the calculation of the immunoreactive area and density. Statistical analysis was performed with ANOVA followed by Tukey test (p <0.05). Results: Animals in the PRP group showed significantly increased expression of the angiogenesis agent CD-31 at all experimental times when compared to the PP group (p <0.0001). However, no differences concerning the expression of the other markers were observed between the groups. Conclusion: The addition of autologous PRP gel to PP meshes can be simply and safely achieved and seems to have a positive effect on implantation site angiogenesis. Further investigations are required to ascertain PPR coated meshes clinical efficacy in prolapses and stress urinary incontinence surgeries.

Presentation delay, misdiagnosis, inter-hospital transfer times and surgical outcomes in testicular torsion: analysis of statewide case series from central Brazil

ABSTRACT Purpose To estimate statewide presentation delay, misdiagnosis rate, inter-hospital transfer times and testicular salvage for testicular torsion patients treated in our state's public health system. Patients and Methods Case series of consecutive testicular torsion patients treated in our state's public health system between 2012-2018. Predictors included presentation delay (time from symptoms to first medical assessment), facilitie's level-of-care (primary, secondary, tertiary), first diagnosis (torsion, epididymitis, other), Doppler-enhanced ultrasound request (Doppler-US) and inter-hospital transfer times, with surgical organ salvage as the main response. We used Bayesian regression to estimate the effect of first examining facilitie's level-of-care, first diagnosis, and Doppler-US on transfer time. Results 505 patients were included, most (298, 59%) with presentation delay >6 hours. Misdiagnosis at first examining facility raised transfer time from median 2.8 to 23.4 (epididymitis) and 37.9 hours (other) and lowered testicular salvage rates from 60.3% (torsion) to 10.7% (epididymitis) and 18.3% (other). Doppler-US had negligible effects on transfer time once controlling for misdiagnosis in the regression model. Although organ salvage in patients presenting before 6 hours at the tertiary facility was high (94.6%, and about 20% lower for those presenting at lower levels-of-care), the overall salvage rate was more modest (46%). Conclusion Our low overall testicular salvage rates originated from a large proportion of late presentations combined with long transfer times caused by frequent misdiagnoses. Our results indicate that efforts to improve salvage rates should aim at enhancing population-wide disease awareness and continuously updating physicians working at primary and secondary levels-of-care about scrotal emergencies.
