The introduction of suburethral sling was a breakthrough in the treatment of stress urinary incontinence in women. The method is highly effective. However, the mechanism of action of a sling and the reasons for surgical failures are not fully understood. Aim: The aim of the study was to assess the impact of sling-pubic symphysis distance on eliminating the symptoms of stress urinary incontinence and urethral funneling. Materials and methods: The analysis included 106 patients who reported 3 to 6 months after sling placement for a follow-up visit encompassing clinical examination and standard ultrasonography. We evaluated the position of sling in relation to the pubic symphysis, urethral length, as well as urethral funneling length and width. Results: Cure criteria were met by 91 patients. Elimination of urethral funneling was achieved in 76.9% (n = 70) of cured patients. Urethral funneling was still present, yet shorter by a mean of 10.2 mm (p = 0.02) than before surgery in the remaining cured patients. There was a 32.5% reduction in the mean relative length of urethral funneling (p = 0.002). No significant differences were found in the pre- and postoperative funneling width. The tape-pubic symphysis distance was lower in cured women: 23.2 mm vs. 26.1 mm in failed women (p = 0.04). Similar observations were made for cured patients with persistent urethral funneling vs. failed patients (22.47 mm vs. 26.0 mm, p = 0.027). There were no differences between cured patients without urethral funneling and cured patients with persistent postoperative funneling (23.5 mm; 22.5 mm; p = 0.417). Conclusions: Tape position in relation to the pubic symphysis is important for the elimination of stress urinary incontinence. Sling location closer to the pubic symphysis reduces the length of urethral funneling, but has no effects on its width in cured patients with persistent postoperative funneling.

Objectives: The aim of the study was the evaluation of repeatability and reproducibility of chosen urethral neck mobility measurements obtained during introital pelvic floor sonography performed with a 2D transvaginal probe. Material and methods: In order to assess the repeatability and reproducibility, independent measurements on the ultra­sound image were taken by two specialists on 92 female patients at rest and at strain (Valsalva maneuver). 2D ultrasound examination was performed introitally with a transvaginal probe (PFS-TV). The location of the urethral internal orifice was defined with coordinates of two points. Point CI marks the urethral anterior edge visualized on ultrasound as closer to the pubic symphysis. Point CII marks the posterior edge visualized more peripherally from pubic symphysis. Results: Repeatability and reproducibility measurements of point CI location and mobility were good and very good (0.6710–0.9961), while of point CII — were medium, good and very good (0.5738–0.9944). Point CI was clearly visible in all cases. It was not possible to accurately mark point CII in 4.3–17.4% of cases. Conclusions: The possibility to visualize point CI in every single case with very good and good repeatability and reproduc­ibility of measurements of this point’s location and mobility allows the usage of CI point as a universal reference point for evaluation of bladder neck mobility and position during PFS-TV in the clinical practice and for research purposes.

Objective: The aim of this study is to evaluate using PFS-TV the mid-term results of our first operative experience with implanting a single incision sling — Ajust™. Material and methods: One and the same surgeon has operated all the patients with symptoms of stress urinary incontinence. Ajust was the only performed procedure. Postoperative evaluation consisted of: a standardized interview and examination, a cough test and a PFS-TV for evaluation of urinary continence and tape location. PFS-TV was performed under standardized conditions at rest and during maximum Valsalva maneuver. Results: This is a retrospective analysis of data from a total of 31 patients who attended a control visit between the 36th and the 50th month following the operation. Sixteen patients (51.6%) were cured. There were statistically significant differences in urethral mobility (p < 0.0007) and tape-urethra distance (p < 0.002) between cured and not-cured group. The difference in urethral length was not statistically significant. 77.8% of women with a hypermobile urethra was cured in contrast to 15.4% with a normobile urethra. Neither of the groups had a hypomobile urethra patient. There were no significant complications intra- or post-operatively. De novo urgency was observed in 1 patient only. Conclusions: Implantation of Ajust tape seems to be a safe mode of operative treatment for SUI in women. Our mid-term results suggest that long term effects might be worse compared to retropubic or transobturator tapes, especially at first operative experience with Ajust. Urethral mobility seems to be an important risk factor for treatment failure after Ajust implantation. It seems that patients that may benefit from Ajust most are women with urethral hypomobility but this needs to be verified with a prospective study.
