Radical hysterectomy during the transition period from traditional to nerve-sparing technique

OBJECTIVE The aim of the study was to compare peri- and postoperative data from patients operated on using the new nerve-sparing technique of radical hysterectomy with data gathered from those who underwent traditional radical hysterectomy. MATERIALS AND METHODS A total of 20 patients with cervical cancer were included in the study. The study was carried out at a time when the authors had started to perform the nerve-sparing technique by using the descriptions from the literature. During the study period 10 patients underwent the nerve-sparing procedure while the other 10 patients underwent traditional radical hysterectomy. The two groups of patients were comparable in terms of mean age, body mass index, FIGO stage, and histological type; additionally, the follow-up period was similar for both groups. RESULTS On the one hand, the mean total operative time (197.5+/-51.4 vs. 155.5+/-39.6 min) and the mean time for the hysterectomy itself (154.5+/-35.4 vs. 123.0+/-29.8 min) were significantly longer in the group operated on with nerve-sparing technique (p=0.05). Postoperatively, on the other hand, a post-void residual urine volume of less than 50 ml was noted to occur significantly faster in the patients who had undergone the nerve-sparing technique (3.5+/-1.4 vs. 9.1+/-4.2 days, p=0.00078). CONCLUSIONS Although during the introductory period nerve-sparing technique brings about an improvement in voiding function, it prolongs the total operative time in comparison to traditional radical hysterectomy.

Angiogenic factor screening in women with mild preeclampsia – New and significant proteins in plasma

HighlightsIncrease in the concentration of 8 proteins in the plasma of women with preeclampsia.IFN‐&ggr;, IL‐6, LIF, Hb‐EGF, HGF, IP‐10, leptin, PDGF‐BB.Significant decrease in the concentration of 3 proteins in the plasma of women with preeclampsia.VEGF, PlGF and follistatin. Introduction The aim of this study was to analyse a panel of 60 angiogenic factors (pro‐angiogenic and antiangiogenic) in the plasma of women with mild preeclampsia. Materials and Methods We recruited 21 women between 25 and 40 weeks gestation with diagnosed mild preeclampsia into the study group and 27 healthy women with uncomplicated pregnancies of corresponding gestational age to that of the study to the control group. We used a quantitative protein macroarray method that allowed for analysis of 60 angiogenic proteins per sample simultaneously. Results We showed a statistically significant increase in the concentration of 8 proteins, interferon gamma (IFN‐&ggr;), interleukin 6 (IL‐6), leukaemia inhibitory factor (LIF), heparin‐binding EGF‐like growth factor (HB‐EGF), hepatocyte growth factor (HGF), C‐X‐C motif chemokine 10 (IP‐10), leptin and platelet‐derived growth factor BB (PDGF‐BB), as well as a significant decrease in the concentration of 3 proteins, vascular endothelial growth factor (VEGF), placental growth factor (PlGF) and follistatin, in the plasma of women with preeclampsia. Conclusion Based on our findings, it seems that protein factors may play an important role in the pathogenesis of preeclampsia, and there are many proteins that have not been studied in PE to date. There are no previous studies assessing the LIF, follistatin, HGF, HB‐EGF and PDGF‐BB concentrations in the plasma of women with PE; therefore, our obtained results indicate that these proteins are new factors that can play an important role in the pathomechanisms of PE.

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.

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.

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 ultra-sound 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 reproduc-ibility of measurements of this points 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.

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 im-provement 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.

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.

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.
