Background: Flat Magnetic Stimulation (FMS) is characterized by a stimulation generated by electromagnetic fields with a homogenous profile. One possible application is the treatment of stress urinary incontinence (SUI). We aimed to compare the objective, subjective, quality of life, and instrumental outcomes in women with SUI not eligible for surgery undergoing either FMS or pelvic floor muscle training (PFMT). Methods: This was a prospective interventional study. After proper counseling, patients with isolated SUI were divided according to their treatment of choice into FMS and PFMT groups. At baseline and after treatment, patients completed the International Consultation on Incontinence Questionnaire-Short Form, the Female Sexual Function Index, and the Incontinence Impact Questionnaire, and volumetric measurement of the urethral rhabdosphincter (RS) was performed. The Patient Global Impression of Improvement questionnaire and stress test defined subjective and objective cure rates, respectively. Results: We observed improvements in urinary-related quality of life scores and an increase in RS volume after FMS compared to baseline. All these outcomes were significantly better compared to women who underwent PFMT. Conclusion: Our study demonstrated that FMS is a safe and effective conservative option for SUI management in terms of objective and subjective cure rates.

Background/Objectives: Urinary tract infections (UTIs) are the most common bacterial infections and one of the most common diseases worldwide. These infections induce an enormous financial and economic burden. The most frequent pathogen in UTIs is Escherichia coli (E. coli), which is responsible for over 85% of cases of cystitis and over 60% of recurrent cases. Repeated antibiotic prescriptions increase the risk of bacteria developing resistance, reducing treatment efficacy and limiting long-term therapeutic options. When traditional preventive methods fail to provide protection, other strategies may be necessary. To investigate the effectiveness of vaccination with Uro-Vaxom for the prevention of UTIs based on currently available studies. Methods: Systematic literature search. Results: The available studies focus almost exclusively on the female sex. Uro-Vaxom decreased the recurrence of UTIs, was overall well tolerated, and reduced the need for antibiotic therapies. Conclusions: Uro-Vaxom is a potential effective and well-tolerated option for reducing the recurrence of UTIs in patients prone to frequent infections. Nevertheless, the retrospective nature of several studies, combined with methodological limitations and variability in study design, precluded a reliable quantitative estimation of the treatment effect.

Introduction: Genitourinary syndrome of menopause (GSM) and vulvovaginal atrophy (VVA) are the most frequent menopause-related clinical entities and are consistently included in the definition of pelvic floor disorders (PFDs). Nonhormonal therapies, such as lubricants and moisturizers, are indicated as first-line treatments, while the “gold standard’’ is represented by topical estrogen products; however, in cancer survivors hormonal treatment is not indicated. For this reason, energy-based therapeutic approaches—for instance, through laser technologies—may be employed as alternative options in this kind of patient; however, there are no studies evaluating the efficacy of a pure diode vaginal laser in the treatment of GSM. As a consequence, with our study, we aimed to evaluate outpatient nonablative diode laser treatment in sexually active women, with contraindications, no response, or refusal of local estrogenic therapy. Methods: This prospective study included patients with GSM, aged ≥ 18 years old, with contraindications, or refusal of local estrogen therapies. Women were evaluated via the use of their Vaginal Health Index (VHI) scores, which consists of five measures: elasticity, fluid volume, pH, epithelial integrity, and moisture. Moreover, the intensity of VVA symptoms (vaginal burning, vaginal itching, vaginal dryness, dyspareunia, and dysuria) was measured using a 10 cm visual analog scale (VAS), where the left extreme of the scale (score = 0) indicated “absence of symptom” and the right indicated “symptom as bad as it could be” (score = 100). Sexual function was evaluated with the Female Sexual Function Index (FSFI-19) questionnaire. The treatment was performed using a Leonardo Dual diode laser (Biolitec Italia Srl, Milano, Italy). The laser treatment consisted of three sessions, one per month. One month after the third session, the VHI, symptom VAS, and FSFI-19 were re-evaluated. In addition, the Patient Global Impression of Improvement (PGI-I) questionnaire was collected. Results: Our study enrolled a total of 26 consecutive patients. All patients were either in menopause or under treatment with gonadotropin-releasing hormone (GnRH). None of the patients reported adverse effects after laser treatment. In total, 19 (73.1%) patients referred improvements of their symptoms according to PGI-I scores. All domains of the FSFI-19 questionnaire, significantly improved after the diode laser treatment. The mean VHI score increased by 3.2 points, from 12.2 to 15.4 (p < 0.001). Additionally, we documented a significant improvement in symptoms affecting the VAS score, from 69.2 to 43.5 points (p < 0.001). Conclusion: A diode vaginal laser is an effective and easily tolerated ambulatory procedure for vaginal functional restoration in the treatment of GSM and VVA.

Introduction and hypothesis: The aim of this study was to translate the English short form of Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and evaluate its validity, internal consistency, and test-retest reliability. Methods: The questionnaire was translated into Italian by standardized procedural steps, and the final version was submitted to women referred to urogynecological outpatient care for genital prolapse or urinary incontinence reporting sexual disorders (cases) or not (controls). For the test-retest evaluation, cases received the questionnaire 2 weeks later. The Wilcoxon test (non-parametric) was used to assess differences between cases and controls. Convergent validity was tested with the Italian version of the FSFI-19. The internal consistency was tested using Cronbachʼs alpha. The degree of concordance/agreement was measured with Cohenʼs kappa. The absolute agreement of test-retest results was tested with the intraclass correlation coefficient (ICC). Results: Sixty women were recruited for the study and answered the questionnaire. The overall rate of missing items was 1.3%. Construct validity was demonstrated, as the questionnaire discriminated significantly between patients with and without symptoms. Convergent validity with FSFI-19 was tested, and a linear correlation between scores was demonstrated (F < 0.001). Internal consistency reliability evaluated with Cronbach's alpha was satisfactory (0.54–0.81). Cohenʼs kappa values as absolute agreement coefficients were between 0.59 and 0.80 (good agreement). Intraclass correlation coefficients ranged between 0.88 and 0.94 (very satisfactory agreement) for each functional domain. Conclusions: The Italian version of the PISQ-12 is reliable, valid, and consistent.

Introduction: Medical advancements are expected to lead to a substantial increase in the population of women aged 80 and older by 2050. Consequently, a significant number of individuals undergoing corrective prolapse surgery will fall into the elderly-patient category. The research indicates a notable rise in complications associated with prolapse surgery in patients older than 80, irrespective of frailty and other risk factors. Despite these challenges, the vaginal approach has been identified as the safest surgical method for pelvic organ prolapse (POP) repair in the elderly population. For this reason, we aimed to investigate the efficacy, complication rate, and functional outcomes associated with vaginal hysterectomy and an apical suspension/high uterosacral ligaments suspension as a primary technique for prolapse repair, both within a cohort of elderly patients. Methods: We retrospectively analyzed patients who underwent transvaginal hysterectomy plus an apical suspension procedure for stage ≥ II and symptomatic genital prolapse between January 2006 and December 2013. Anatomical and functional outcomes were evaluated. The Patient Global Impression of Improvement (PGI-I) score was used to evaluate subjective satisfaction after surgery. Results: Sixty-five patients were included in the analysis. The median age was 81.3 years. All individuals exhibited an anterior compartment prolapse stage II or higher, and the majority also a central prolapse stage II or higher. Notably, all participants reported symptoms of vaginal bulging. Over half of the population (58.6%) complained of incomplete bladder emptying. The intervention for all participants involved a vaginal hysterectomy with an apical suspension. Sixty-three patients (96.9%) and forty-four patients (67.6%) underwent a simultaneous anterior or posterior repair, respectively. Long-term complications (>30 days from surgery) were observed during follow-up, with a median duration of 23 ± 20 months. Seven (10.7%) anatomical recurrences were recorded, five (7.69%) concerning the anterior compartment, one (1.5%) the central, and three (4.6%) the posterior. Nevertheless, none of them necessitated further surgical intervention due to symptoms. Significant anatomical improvements for the anterior, central, and posterior compartments were noticed, compared to preoperative assessment (p < 0.001 for Aa and Ba, p < 0.001 for Ap and Bp, and p < 0.001 for C). PGI-I values established that 100% of patients were satisfied (PGI-I ≥ 2), with a median score of 1.12. Consequently, objective and subjective cure rates were 89.5% and 100%, respectively. Conclusion: Vaginal hysterectomy combined with apical suspension, particularly high uterosacral ligaments suspension, is a safe and effective primary surgical approach, even in elderly patients.

Background and Objectives: Urodynamics is considered the gold standard for lower urinary tract functional assessment. However, it requires very specific skills and training, which are currently difficult to master due to its reduced use. Moreover, no studies or data are available to define the workload and the learning curve of this diagnostic tool. As a consequence, we aimed to evaluate the learning curve of residents with no previous experience to correctly perform and interpret urodynamics, and properly address and manage patients with pelvic floor disorders based on urodynamics findings. Materials and Methods: This prospective study analyzed a series of proficiency parameters in residents performing urodynamics under consultant supervision, including the following: duration of procedure, perceived difficulty, need for consultant intervention, accuracy of interpretation, and therapeutic proposal. The number of procedures performed was then divided into groups of five to evaluate the progressive grade of autonomy (technical and full management autonomy) reached by each resident. Results: In total, 69 patients underwent urodynamics performed by three residents, with every resident performing at least 20 exams. Duration of procedure, perceived difficulty, need for consultant intervention, accuracy of interpretation, and the appropriateness of the hypothetical proposal of management/treatment based on their interpretation of clinical data and urodynamic findings was shown to be directly related to the number of exams performed. Technical autonomy in the execution of uroflowmetry was reached in the group performing 6–10 procedures, while technical autonomy in the execution of cystomanometry with pressure/flow study was obtained in the group of 16–20 procedures. The latter corresponded also to the gain of full autonomy which also included an optimal therapeutic proposal. Conclusion: We found that there is a tangible learning curve for urodynamics in terms of several proficiency parameters. A workload of 5 uroflowmetries and 15 cystomanometries with pressure/flow studies may be adequate to complete the learning curve.
