Minimally Invasive Treatment of Stress Urinary Incontinence in Women: A Prospective Comparative Analysis between Bulking Agent and Single-Incision Sling.

INTRODUCTION: The study aims to compare the efficacy and safety of bulking agents and single-incision slings in the treatment of urinary incontinence in 159 patients during a 29-month follow-up period. MATERIAL AND METHODS: Of the 159 patients suffering from stress urinary incontinence, 64 were treated with bulking agents (PAHG Bulkamid®) and 75 with a single-incision sling (Altis®). The ICIQ-UI-SF (Incontinence Questionnaire-Urine Incontinence-Short Form), PISQ-12 (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaires short form), FSFI (Female Sexual Function Index), FSDS (Female Sexual Distress Scale), and PGI-I (Patient Global Improvement Index) were used to assess efficiency and quality of life. RESULTS: The bulking agents showed high efficacy and safety during the 29-month follow-up. Post-operative complications were recorded in both groups, with only two significant differences. The Bulkamid group experienced no pain, while 10.8% of the ALTIS group experienced groin pain and 5% experienced de novo urgency. Furthermore, patients treated with bulking agents experienced reduced nicturia (0.78 vs. 0.92 in patients treated with single-incision slings.). In both groups, we noticed a significant improvement in QoL (quality of life), with a halved ICIQ-UI-SF (International Consultation on Incontinence Questionnaire-Urine Incontinence-Short Form) score which was completed to assess the impact of urine symptoms. After 24 months of therapy, the Bulkamid group saw a decrease from 14.58 ± 5.11 at baseline to 5.67 ± 1.90 (p < 0.0001), whereas the ALTIS group experience a decrease from 13.75 ± 5.89 to 5.83 ± 1.78. Similarly, we observed an improvement in sexual function, with the number of sexually active patients increasing from 29 to 44 (56.4%) in the Bulkamid group (p = 0.041) and from 31 to 51 (61.7%) in the ALTIS group (p = 0.034). According to the most recent statistics, the PISQ-12, FSFI, and FSDS scores all demonstrated an improvement in women's sexual function. CONCLUSIONS: In terms of efficacy and safety, bulking agents had notable results over the 29-month follow-up period. Furthermore, the patients treated with bulking agents reported a lower incidence of postoperative complications and a no discernible difference in terms of quality of life and sexual activity compared to the ones treated with single-incision slings. Bulking agents can be considered a very reliable therapeutic option based on accurate patient selection.

Validation of an automated software (Smartpelvic™) in assessing hiatal area from three dimensional transperineal pelvic volumes of pregnant women: comparison with manual analysis.

OBJECTIVES: The aim of this investigation was to evaluate the agreement between a manual and an automatic technique in assessing levator hiatus area (LHA) during pregnancy from three-dimensional (3D) pelvic floor volumes obtained by trans-perineal ultrasound (TPUS). METHODS: 3D volumes were acquired during rest, maximum pelvic floor contraction and Valsalva maneuver from 66 pregnant women. Manual selection of LHA and automatic software (Smart Pelvic™) were applied on TPUS volume starting from a C-plane view. To evaluate intra- and inter-observer variability measurements of LHA were performed twice by the same operator and once by a second sonographer. Reference hiatal contours obtained manually by the first operator were compared with the automated ones. Reproducibility was evaluated by intraclass correlation coefficients (ICC) and Bland-Altman plots. RESULTS: LHA measurement, using automatic software, achieved excellent intra-observer and inter-observer reproducibility in pregnant women both at rest and after dynamic analysis (ICC>0.9). Further, an excellent agreement resulted between manual selection of the LHA and automatic imaging (ICC>0.9). The average time taken to obtain LHA manually was significantly longer when compared to the automatic analysis (p≤0.0001). CONCLUSIONS: Smart pelvic software resulted from a reliable method for automatically measuring the LHA, showing high reproducibility and accuracy.

Lymphopenia in patients affected by SARS-CoV-2 infection is caused by margination of lymphocytes in large bowel: an [18F]FDG PET/CT study.

BACKGROUND: To investigate the cause of lymphopenia in patients with newly diagnosed COVID-19, we measured [18F]FDG uptake in several tissues, including the ileum, right colon, and caecum at diagnosis and after recovery and correlated these measurements with haematological parameters. METHODS: We studied, by [18F]FDG PET/CT, 18 newly diagnosed patients with COVID-19. Regions of interest were drawn over major organs and in the terminal ileum, caecum, and right colon, where the bowel wall was evaluable. Five patients were re-examined after recovery, and three of them also performed a white blood cell scan with 99mTc-HMPAO-WBC on both occasions. Complete blood count was performed on both occasions, and peripheral blood lymphocyte subsets were measured at diagnosis. Data were analysed by a statistician. RESULTS: Patients had moderate severity COVID-19 syndrome. Basal [18F]FDG PET/CT showed focal lung uptake corresponding to hyperdense areas at CT. We also found high spleen, ileal, caecal, and colonic activity as compared to 18 control subjects. At recovery, hypermetabolic tissues tended to normalize, but activity in the caecum remained higher than in controls. Regression analyses showed an inverse correlation between CD4 + lymphocytes and [18F]FDG uptake in the caecum and colon and a direct correlation between CD8 + lymphocytes and [18F]FDG uptake in lungs and bone marrow. WBC scans showed the presence of leukocytes in the caecum and colon that disappeared at recovery. CONCLUSIONS: These findings indicate that lymphopenia in COVID-19 patients is associated with large bowel inflammation supporting the hypothesis that CD4 + lymphocytes migrate to peripheral lymphoid tissues in the bowel.
