Introduction and hypothesis: Various instruments are used to evaluate the severity of stress urinary incontinence (SUI) in clinical trials for SUI surgery. We conducted a scoping review with the primary aim of investigating the use of such instruments.

Methods: A comprehensive search in PubMed/MEDLINE, Cochrane Library, ClinicalTrials.gov, and WHO ICTRP was carried out. Inclusion criteria were studies including patients undergoing surgical intervention for SUI with assessment of SUI severity performed pre- and post-operatively. Exclusion criteria were nonprospective studies, nonrandomized studies, studies not in the English language, and the absence of reporting the methods of SUI severity evaluation in the study.

Results: In total, 8,886 articles were identified, yielding 100 papers for data extraction. The most frequent interventions were mid-urethral slings (85 studies), Burch colposuspension (10 studies), and the use of bulking agents (3 studies). The most frequently used instruments for objective evaluation of SUI were urodynamics (90 studies), nonvalidated cough stress test (83 studies), and 1-h pad test (28 studies). The most frequently used instruments for subjective evaluation were bladder diary (37 studies), Incontinence Impact Questionnaire-7 (26 studies), and Urinary Distress Inventory-6 (23 studies). There were three studies reporting results according to the severity of pre- and post-operative SUI.

Conclusions: There is significant heterogeneity regarding the instruments used to evaluate the severity of SUI in surgical trials for female incontinence. There is a paucity of data regarding results according to the pre-operative severity of SUI. Hence, commonly agreed standardized methods for the assessment of SUI severity are needed to improve comparability between clinical trials for SUI surgery.

Introduction and hypothesis: Surelift is a transvaginal synthetic mesh (TVM) kit that is intended to treat anterior and apical pelvic organ prolapse (POP). The kit can be configured to use an anterior-apical (Surelift) or anterior (Surelift A) approach. The aims of this study were to evaluate the short-term objective and subjective outcomes of the different approaches at the 1-year follow-up.

Methods: From June 2018 to April 2021, a total of 280 patients with symptomatic advanced POP (stages III and IV) had surgery with the Surelift or Surelift A. The primary outcome was postoperative de novo stress urinary incontinence (SUI), as well as subjective evaluation based on the Urinary Distress Inventory 6 (question 3 score > 1) and Incontinence Impact Questionnaire 7, during the 1-year follow-up period. Secondary outcomes measured quality of life, the presence of lower urinary tract symptoms, and complications.

Results: In total, 265 patients were assessed. Among these, 137 had Surelift, whereas 128 underwent Surelift A with SSF. At 1-year postoperative follow-up, de novo urodynamic stress incontinence occurred more frequently in the Surelift group than in the Surelift-A group (28.8% vs 9.1% respectively, p = 0.012). Additionally, Surelift patients had a higher rate of de novo SUI than Surelift A (33.2 vs 11.4 respectively, p = 0.013). Both study groups experienced improvements in their quality of life indicators.

Conclusions: The Surelift device is a safe and effective technique of treating advanced-stage POP. De novo urine incontinence appears to be more common in the Surelift group than in the Surelift-A group. We found good anatomical outcomes and subjective relief in both study groups, with a low complication rate.

Introduction and hypothesis: Sacrocolpopexy (SCP) is an established surgical procedure for apical vaginal vault prolapse. There remains significant variation amongst surgeons in both the surgical steps and concomitant surgeries utilised when undertaking an SCP.

Methods: This review article is aimed at summarising the evidence and providing a detailed update of SCP in modern practice, reviewing contemporary evidence behind its indications, efficacy, outcomes, surgical steps, and complications.

Results: Sacrocolpopexy remains the gold standard for post-hysterectomy apical prolapse based on good long-term outcomes, patient satisfaction and low complication rates. SCP with concomitant total hysterectomy is not recommended owing to high rates of mesh exposure. The laparoscopic approach remains the preferred option in terms of low morbidity, quicker recovery and lower cost than alternative access options. For optimal outcomes an SCP should be performed with monofilament mesh, using absorbable sutures and with a paravaginal repair for cystocele.

Conclusions: Although SCP has become increasingly utilised for apical prolapse, its established efficacy regarding anatomical outcomes, patient satisfaction, and complications is in the context of post-hysterectomy prolapse. SCP with concomitant total hysterectomy has higher rates of mesh exposure. The efficacy and safety of SCP with sub-total hysterectomy or hysteropexy have not been clearly established and require further assessment through well-designed, rigorous randomised controlled trials.

Introduction and hypothesis: The purpose of this study was to evaluate medium-term sexual function following midurethral sling (MUS) surgery.

Methods: This was an ambidirectional observational study with a nested matched case-control study performed in a tertiary urogynecology referral center. We assessed sexual discomfort and function using the Pelvi-Perineal Surgery Sexuality Questionnaire (PPSSQ), pre- and postoperatively, in a patient cohort that comprised patients who underwent an MUS procedure between January 2014 and December 2019. We recruited a group of volunteers without a previous history of MUS surgery. The nested case-control study comprised a subgroup of cases from the patients' cohort matched to controls from the volunteer's cohort. Cases and controls were matched for age and menopausal status at a 1:1 ratio.

Results: A total of 118 patients and 128 volunteers were recruited. Of these, 105 cases and 105 controls comprised the nested case-control study. There was no statistically significant difference in the mean discomfort and pain scores between cases and controls (19.8 ± 21.2 vs 15.4 ± 15.7 respectively; p = 0.19 primary outcome). Similarly, there was no difference in mean sexual health scores. However, the rate of reported sensation of an obstruction in the vagina was significantly more in cases (16%) than in controls (2.6%; p = 0.001). There were no significant differences between patient-reported sexual function at follow-up compared with their recollection before surgery.

Conclusion: Midurethral sling surgery does not seem to impair the quality of sexual life in the medium term.

Introduction and hypothesis: The internal iliac artery stands as the main blood supplier of the pelvis, serving as the primary source of blood for the pelvic viscera while also nourishing the musculoskeletal framework within. The arterial anatomy of the pelvis exhibits a vast array of variations, especially regarding the branching pattern of the internal iliac arteries. The posterior division of the internal iliac artery (PDIIA) may also have variable topography, especially regarding the location of its origin in the pelvic region.

Methods: A retrospective study was carried out to determine the anatomical variations, prevalence, and morphometric data of the PDIIA and its branches. A total of 75 computed tomography angiographies were analyzed.

Results: The most prevalent branch of the PDIIA was the superior gluteal artery, as it was present in 114 of the studied cases (77.03%). The median diameter of the PDIIA at its origin was 6.66 mm. The median cross-sectional area of the PDIIA at its origin was set to be 34.59 mm².

Conclusion: Our study highlights the critical significance of understanding the PDIIA and its branches in surgical interventions aimed at managing pelvic hemorrhage. The present study provides valuable insights into the precise localization and characteristics of the PDIIA and its branches, which are essential for surgical procedures targeting specific vessels to control bleeding effectively. Owing to the high level of variability of the branching pattern of the PDIIA, a novel classification system consisting of six types was created.

Introduction and hypothesis: Pelvic floor muscle ultrasound is an important clinical tool for improving motor coordination and even strength. Although the gold standard approach involves transperineal probe placement, this is not always feasible with sensitive populations, requires privacy owing to probe placement, and additional sonography training. This article introduces a novel transabdominal method for measuring pelvic floor muscle motion that incorporates a reference point within the bladder. The hypothesis is that the novel measurement will correlate positively with transperineal measurements.

Methods: A total of 55 women (15 nulliparous, 40 parous; 20 continent, 35 incontinent) performed pelvic floor muscle contraction and strain. Transabdominal ultrasound measured bladder diagonal length (BDL) and transperineal ultrasound measured bladder neck height (BNH), levator plate length (LPL), and levator plate angle (LPA). Spearman's test measured the correlation between the measurement outcomes and an independent t test compared outcomes based on parity and stress urinary incontinence symptom status.

Results: Spearman's correlation showed moderate positive correlations between the pelvic floor measurements for both tasks, which reduced slightly when grouping by parity and symptom status. Group differences were significant for BDL during the muscle contraction, factoring in SUI symptoms (p = 0.019) and parity status (p = 0.005) and LPL during contraction, factoring in parity status (p = 0.033).

Conclusions: BDL correlates with BNH, LPL, and LPA with slightly reduced correlation when factoring in parity and continence status. The advantages of the method include accessibility for sensitive populations, nontraditional positions due to the anatomical reference point, functional locations due to limited privacy needs, and minimal training required for pelvic floor therapists to incorporate into rehabilitation.

Introduction and hypothesis: Vaginal delivery and resulting pelvic floor muscle (PFM) dysfunction are significant risk factors for pelvic floor dysfunction (PFD). Despite this, the biological basis underlying PFD after childbirth remain unclear. This study was aimed at assessing the early response of the vaginal wall and PFM to simulated birth injury (SBI) in rats.

Methods: Forty female Sprague-Dawley rats were divided into four groups: control (sham operation), and 1, 4, and 14 days post-injury. In the SBI groups, a catheter was inserted into the vagina with 130 g of weight attached to the end, and the balloon was inflated to 5 ml for 2 h. Evaluation of vaginal tissues and PFMs included histological, immunohistochemical, Western blot, and uniaxial biomechanical testing.

Results: In the vaginal wall, the SBI group showed significantly lower COL1A1 expression and higher MMP-2 and MMP-9 expression. At 4 and 14 days post-injury, there was a significant decrease in PFM fiber area and increased collagen content. The SBI group also exhibited significant increases in the expression of Nrf2, NQO1, HO-1, and SOD-2, indicating involvement of oxidative stress in both the vaginal wall and PFMs. Protein expression of Pax7 and MyoG, as well as the number of fibers with centralized nuclei, continued to increase significantly after SBI. Additionally, the vaginal wall of the SBI group showed a decreasing trend in tensile strength and elastic modulus, with a greater ultimate strain.

Conclusion: Extracellular matrix remodeling, oxidative stress, decreased biomechanical properties, and muscle dysmyogenesis may collectively contribute to increased susceptibility to PFD development.
