Transvaginal six-arm mesh OPUR in women with apical pelvic organ prolapse — analysis of short-term results, pelvic floor ultrasound evaluation

Objectives: Analysis of feasibility, efficacy and short-term results after six-arm transvaginal mesh OPUR implantation in women with apical prolapse. Material and methods: The same surgeon operated all of 39 women using mesh OPUR. Preoperatively patients had a standardized interview and clinical examination. Intraoperative and postoperative complications were analyzed. Postoperative evaluation included standardized interview, clinical examination and standardized pelvic floor ultrasound performed with 2D transvaginal probe and 4D abdominal probe. Results: There was no complication that needed operative intervention. Hematomas in 3 patients resolved spontaneously. Transient voiding difficulties which lasted less than 7 days were observed in 5 patients. No erosion was observed. Comparison of pre- and postoperative results in 34 women revealed that in all 3 compartments improvement in POP-Q scale was statistically significant (p < 0.0000). One patient with malposition and rolled up mesh needed re-operation. During PFS-TV in 94.1% of patients urethra was normobile or hypermobile. In all of the patients urethral end of the mesh was positioned far enough from the middle part of the urethra (ultrasound) to implant suburethral sling without risk of collision. Sexually active women did not inform of any important discomfort or pain during intercourse. Conclusions: It seems that six-arm OPUR mesh, if implanted under strict surgical rules, gives low risk of complications and high chance to successfully reduce POP symptoms in short term after the operation. It seems that OPUR mesh should not have negative influence on the results after anti-incontinence suburethral sling

Urethral funneling visualized during pelvic floor sonography — analysis of occurrence among urogynecological patients

Objectives: There are different diagnostic methods used in women with urinary incontinence symptoms such as: medical history, voiding diary, cough test, pad test, urodynamic testing. None of them is optimal. The aim of this study is to analyze the correlation between urethral funneling visualized during pelvic floor sonography and symptoms of stress urinary incontinence. Material and methods: We have performed a retrospective analysis of 657 complete datasets of patients who attended our urogynecological clinic for diagnostics. Women with wet overactive bladder were excluded from the analysis. Tests used in our clinic included: standardized interview and questionnaire, clinical exam, cough test. Pelvic floor sonography with a transvaginal probe in women with filled bladder was performed to assess the urethral length and the urethral funneling during maximal Valsalva maneuver. Results: In all patients with clinical SUI symptoms and with a positive cough test the urethral funneling length during Valsalva maneuver was > 50% of urethral length (long urethral funneling). In 83.7% of women without SUI the urethral funneling was absent. In the remaining 16.3% funneling was visible but its relative length was less than 50% of urethral length and urine flow was not observed (short urethral funneling). Conclusions: Long urethral funneling (> 50% of urethral length) seems to be a characteristic sign for SUI in women. The presence of urethral funneling shorter than 50% of urethral length (short urethral funneling) is not a SUI symptom — it is probably a sign of asymptomatic funneling of bladder neck

Prognostic significance of TEM7 and nestin expression in women with advanced high grade serous ovarian cancer

Objectives: Tumor endothelial marker 7 (TEM7) and nestin have been proposed to be new candidates for neoangiogenesis assessment. Nestin is also cancer stem cells marker in various malignant tumors. AIMS. To investigate the expression of TEM7, nestin and nestin-related microvessel density (MVD) in high-grade serous ovarian cancer samples and to study their correlation with overall survival (OS) and disease-free survival (DFS) times. Material and methods: Tumor samples obtained from 70 women with FIGO IIIc/IV ovarian serous cancer were studied with immunohistochemistry. Results: Patients median age was 54 yrs (range: 29–72 years), 86% died of the disease with median OS = 28.5 months and median DFS = 10 months (3 years DFS = 19%; 5 years. DFS = 13.8%). High nestin expression was found in 16 (23%) patients with 3 years and 5 years OS of 14% and 0%. In low-nestin expression group OS and DFS were 42% and 25%, respectively. Median nestin-MVD (16, range:12–23) was not correlated with cancer cells nestin expression and with both DFS and OS. High TEM7 expression was found in 29 women (41%) of whom 21 (72%) died of the disease. A 5-year OS in these women was 27% as compared to 8% in low TEM7 expression group, but TEM7 presence had no association with nestin, nestin-MVD and both OS and DFS. Conclusions: Nestin as a marker of cancer stem cells may assist in the prediction of OS and DFS in women with high grade serous ovarian cancer. Nestin may also be considered a novel therapeutic target for antiangiogenic agents

Perspectives for the pharmacological treatment of overactive bladder syndrome

It has been found that antimuscarinic drugs, viewed as the “gold standard” in overactive bladder syndrome (OAB) treatment, have an unsatisfactory tolerance profile and limited clinical effectiveness. This fact has given a clear impetus to search for new options in OAB pharmacotherapy. The conducted pre-clinical trials have led to the development of new solutions for the treatment of OAB, which stand a good chance of being applied in clinical practice. The said compounds are characterised by higher receptor and organ specificity than currently used medications

The effectiveness of a pre-pubic four-arm NAZCA-TC mesh in treating cystocele and stress urinary incontinence simultaneously — results controlled with a pelvic floor ultrasound. A preliminary study

  Objectives: It is controversial whether pelvic organ prolapse and stress urinary incontinence (SUI) should be treated simultaneously with a single surgery or separately with two procedures. The pre-pubic four-arm NAZCA-TC® mesh was invented to treat cystocele and SUI with a single procedure. The objective of this study is to analyze short-term results after the implantation of NAZCA-TC mesh. Material and methods: A total of 18 women underwent the evaluation of results of mesh implantation within a 24 to 36 months follow-up. Pre-operatively, patients were examined under standardized conditions. Postoperatively we analyzed the following: standardized interview and examination as well as pelvic floor ultrasound: 2D with a transvaginal probe and 4D with an abdominal probe. Results: There was one case of intraoperative bladder damage noticed and repaired followed with NAZCA implantation. In 2 cases vaginal erosion was found that healed successfully after re-operation. In 3 cases hematomas were observed but resolved spontaneously. After the surgery there was a statistically significant improvement of prolapse in anterior (p < 0.0003) and in central (p < 0.001) compartment. Six women (33.3%) had no stress urinary incontinence symptoms during the control visit but we did not find a statistically significant improvement in SUI symptoms after the procedure. We recorded no case of hypomobile urethra after the surgery. The mesh covered > 50% of the urethral length in all of the patients. Conclusions: Mid-term results showed that implantation of NAZCA TC mesh allows to achieve statistically significant im­provement in reducing cystocele coexisting with enterocele in over 65% of patients. A complete cure from stress urinary incontinence was confirmed in 1/3 of patients. NAZCA-TC covered more than 50% of the urethral length, which can possibly have a negative influence on the effectiveness of the suburethral tape

Novel biomarkers of overactive bladder syndrome

The social aspect of overactive bladder syndrome (OAB) and the lack of objective diagnostic methods for this syndrome have spurred research into its potential biomarkers which can constitute useful diagnostic tools, while also allowing the evaluation of the intensity of clinical symptoms and the efficacy of implemented pharmacotherapy in OAB patients. Due to the complex etiopathogenesis of this syndrome, the researchers are seeking biomarkers connected with inflammation or nerve growth. The aim of this review was to analyse the latest literature data regarding potential biomarkers in OAB. The most promising opportunities are connected with the diagnostic use of the nerve growth factor (NGF), the brain derived neurotrophic factor (BDNF), C-reactive protein (CRP), prostaglandins and cytokines. Despite the most promising results to date having been obtained with regards to neurotrophic factors, it seems that, at the moment, none of these meets the criteria for becoming an isolated OAB marker. It is also suggested that the combined use of several biomarkers will facilitate obtaining the appropriate level of specificity and selectivity to allow their use in clinical practice

Adjustable single incision sling Ajust — the effects of first operations controlled by pelvic floor sonography

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

The analysis of repeatability and reproducibility of bladder neck mobility measurements obtained during pelvic floor sonography performed introitally with 2D transvaginal probe

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

Frequency of "BRCA1" and "BRCA2" causative founder variants in ovarian cancer patients in South-East Poland

Background Causative variants in BRCA1 and BRCA2 are well-established risk factors for breast and ovarian cancer. In Poland, the causative founder variants in the BRCA1 are responsible for a significant proportion of ovarian cancer cases, however, regional differences in the frequencies of various mutations may exist. The spectrum and frequency of BRCA1/2 mutations between ovarian cancer patients have not yet been studied in the region of South-East Poland. Methods We examined 158 consecutive unselected cases of ovarian cancer patients from the region of Podkarpacie. We studied 13 Polish causative founder variants in BRCA1 (c.5266dupC, c.4035delA, c.5251C > T, c.181 T > G, c.676delT, c.68_69delAG, c.3700_3704delGTAAA, c.1687C > T, c.3756_3759delGTCT) and in BRCA2 (c.658_659delGT, c.7910_7914delCCTTT, c.3847_3848delGT, c.5946delT). Results A BRCA1 causative founder variants were detected in 10 of the 158 (6.3%) ovarian cancer cases. BRCA2 causative founder variants were not observed. The c.5266dupC mutation was detected in 6 patients, c.181 T > G mutation in 3 patients and the c.676delT mutation in 1 patient. The median age of diagnosis of the 10 hereditary ovarian cancers was 55.5 years of age. Conclusions The frequency of 13 causative founder variants in Podkarpacie was lower than in other regions of Poland. Testing of three BRCA1 mutations (c.5266dupC, c.181 T > G, c.676delT) should be considered a sensitive test panel
