The association between NOTCH3 expression and the clinical outcome in the urothelial bladder cancer patients.

Disrupted NOTCH activity is a driving event in urothelial bladder cancer (UBC). After activation by hypoxia, the NOTCH3 receptor participates in tumor cell proliferation, acquisition of the epithelial-mesenchymal transition phenotype, and angiogenesis. The aim was to analyze the association of NOTCH3 expression with histopathological and clinical parameters, and to determine its predictive impact on the clinical outcome in UBC patients. The present research included 614 UBC samples incorporated in paraffin tissue microarrays, evaluated by immunohistochemistry for NOTCH3 expression. The accrual period was four years, while the follow-up period was two years. The membranous expression was semi-quantified (0-3), and the mean degree was 1.81±0.94. Criteria for semi-quantification the NOTCH3 expression were the intensity of the staining and the percentage of positive cells. The samples with negative (0) and weak (1) NOTCH3 immunohistochemical (IHC) score were considered negative, while the samples that showed moderate (2) and strong (3) expression were considered positive. Higher degree of positivity was associated with higher risk of cancer-specific mortality (p<0.001). Independent predictors for cancer-specific mortality were NOTCH3 expression and high stage (p<0.001). NOTCH3 expression was not a statistically significant predictor of recurrence-free survival (p=0.816). This study indicated that NOTCH3 is a predictor of poor outcome, suggesting that the NOTCH3 could be potentially reliable IHC marker for selecting the UBC patients that would require more intensive follow-up, especially if they diagnosed in higher stage, with divergent differentiation in pathological report, and without recurrences which would lead them to more frequent medical assessments.

Laparoscopic minimally invasive sacrocolpopexy or hysteropexy and transobturator tape combined with native tissue repair of the vaginal compartments in patients with advanced pelvic organ prolapse and incontinence.

INTRODUCTION AND HYPOTHESIS: The aim of the study was to evaluate hysterectomized and non-hysterectomized patients with prolapse and incontinence. Laparoscopic sacrohysteropexy (LSHP) and minimally invasive sacrocolpopexy (LMSCP) were done in combination with transobturator tape (TOT) and native tissue repair of the anterior and posterior vaginal compartments in patients with pelvic organ prolapse (POP) and occult, stress, or urinary incontinence (SUI). The hypothesis is that both methods are successful. METHODS: A total of 81 patients with POP were evaluated: 44 had vaginal vault prolapse (POPQ points Ba, C, and Bp were 1.2, 2.6, and 0.4, respectively) and 37 had uterine prolapse (POPQ points Ba, C, and Bp were 1.8, 1.7, and 1.3, respectively). LMSCP (which means less dissection of the vagina in its upper third and avoiding possible collision with the ureters anteriorly or the rectum posteriorly) was performed in patients with vault prolapse, whereas patients with uterine prolapse underwent LSHP. Transobturator tape (TOT) was placed in all patients to treat symptomatic and occult urinary incontinence. Systematic anterior and posterior colporrhaphy was performed in both groups. RESULTS: Both groups showed anatomic (p < 0.0001) and symptomatic improvement (p < 0.001-p < 0.05). Voiding was significantly improved after surgery without postoperative incontinence (p < 0.001). There was no significant difference between groups regarding duration of surgery (p = 0.06), hospital stay (p = 0.13), blood loss (0.83), Clavien-Dindo grade 3 (p = 0.87), and Clavien-Dindo grade 1-2 (p = 0.92) complications. CONCLUSION: Minimally invasive LSCP or LSHP combined with TOT and native tissue repair of the anterior and posterior vaginal compartment is a successful treatment for POP.

A martius flap in the treatment of iatrogenic distal urogenital fistula

ABSTRACT Introduction: Distal urogenital fistulas (DUF) are usually iatrogenic and are uncommon in Europe. They occur in the urethra or near the bladder neck, and can be caused by vaginal hysterectomy, para-urethral cyst surgery, or erosion of the bladder or urethra from tension-free slings or meshes. The psychological and physical health consequences of DUF are devastating because most patients consider themselves "healthy" before surgery. Incontinence can appear after successful DUF closure due to previously occult incontinence or urethral incompetence. Additional surgery for incontinence is sometimes necessary to achieve satisfactory outcome. Materials and Methods: A Martius flap was used in 23 patients between 2000 and 2015. Patient age range was 38-75 years (mean, 58.7). DUF was due to gynecologic surgery for benign disease (15 / 23; 65.2%), mesh / sling erosion (2 / 23; 8.7%), and malignancy (6 / 23; 26.1%). The follow-up period was one year. Results: DUF was closed in 22 patients (95.6%). Satisfaction and complete dryness was achieved in 16 patients (69.6%) after the first procedure. Postoperative complications were: postoperative hematoma in 1 (4.4%), primary failure in 1 (4.4%), overactive bladder (OAB) syndrome in 3 (13.2%) and postoperative incontinence in 6 (26.4%) patients. A fascial sling was placed in patients with incontinence. All patients were dry after the secondary surgery. Anticholinergics were used for the treatment of OAB syndrome. Discomfort at the flap harvesting site was of minor importance. Finally, 22 out of 23 patients (95.6%) were satisfied. Conclusion: A Martius flap and additional fascial sling could be successfully used to optimize DUF treatment.

Epidemiologic study of urolithiasis in seven countries of South-Eastern Europe: S.E.G.U.R. 1 study.

OBJECTIVE: To investigate some epidemiological aspects of kidney stones in the South- Eastern European area. MATERIALS AND METHODS: From September 2015 to December 2015, 538 consecutive patients were treated and evaluated for reno-ureteral stones in eight departments in Bulgaria, Greece, Italy, FYR Macedonia, Romania, Serbia and Turkey. RESULTS: The age of onset was lower in Turkey and higher in Italy. The rate of recurrent patients was higher in Romania and Serbia, while first renal stone formers were more frequent in Italy. The previous history of kidney stones, the characteristics of the stones and the dietary habits of the patients were different in different countries. In Bulgaria, Greece and Romania larger calculi from recurrent patients were more frequent. In Italy and Turkey smaller calculi from first renal stone formers were more frequent. CONCLUSIONS: The previous history of kidney stones, the characteristics of the stones and the dietary habits of the patients were different in different countries. A common dietary pattern associated with the formation of kidney stones was not observed, but each country showed different risk factors.

Simultaneous self-created transobturator tape and laparoscopic extraperitoneal vaginal support in patients with stress urinary incontinence and prolapse of the anterior and apical vaginal compartments.

OBJECTIVE: Stress urinary incontinence (SUI) is frequently associated with prolapse of the apical and anterior vaginal compartments. The standard treatment of SUI is transobturator tape (TOT). The usual treatment of prolapse (anterior colporrhaphy) has a high recurrence rate. The aim of this study is to evaluate the results of the treatment of SUI and concomitant anterior and apical prolapse with self-created transobturator tape and simultaneous laparoscopic anterior and apical support. STUDY DESIGN: A total of 36 patients with SUI and prolapse of the anterior and apical compartments were underwent operations. The mean follow-up was 18 months. Self-created transobturator tape and laparoscopical support of the anterior and apical compartment prolapse were performed in all patients. The most important symptoms of prolapse and incontinence, the anatomical outcome, and complications were evaluated before and after the surgery. RESULTS: Treatment of incontinence and anterior and apical prolapse was successful in 33/36 (91.7%), 30/36 (83.3%) and 31/36 (86.1%) patients, respectively (p<0.0001). There is a significant reduction of vaginal bulging and pelvic pressure (p<0.0001). Frequency and urgency were significantly reduced (p<0.0007 and p<0.03 respectively). There was no significant deterioration of the posterior compartment. The most important complications were bladder perforation in 2/36 (5.5%) patients and temporary urinary retention in 3/36 (8.3%) patients (Clavien-Dindo grade 3). CONCLUSION: Simultaneous laparoscopic anterior and lateral extraperitoneal support and transobturator tape are effective in the treatment of patients with both conditions.

Self-created transobturator tape treatment of stress urinary incontinence without prior urodynamic investigation.

OBJECTIVES: The purpose of this study was to evaluate and compare the results of tension free self-created transobturator tape (SCTOT) with the standard industrially created transobturator tape (ICTOT) in the treatment of stress urinary incontinence (SUI). STUDY DESIGN: A prospective study of the treatment of SUI with SCTOT (67 patients) and ICTOT (47 patients) was performed. SCTOT was created from polypropylene mesh and monofilament sutures. The symptoms were evaluated before and after the surgery with the following: the Incontinence Impact questionnaire (IIC-7), the urogenital distress inventory (UDI-6), and the International Continence impact questionnaire short form (ICIQ5-SF). The overactive bladder symptom score (OABSS) was used to classify patients in the SUI or the mixed urinary incontinence (MUI) group. The follow up period was 18 months. Cure was defined as a negative stress test and no need for additional surgery. RESULTS: Objective cure was achieved in 56/67 (83.5%) participants in the SCTOT group and in 40/47 (85.1%) participants in the ICTOT group (p>0.05). There was a significant improvement in IIC-7, UDI-6, ICIQ5-SF and OABSS in both groups. Improvement was better in the group with pure SUI than in patients with MUI, but this difference was not significant. Postoperative infection occurred in 5/67 (7.4%) participants and in 5/47 (10.6%) patients in the SCTOT and the ICTOT group, respectively. De novo overactive bladder symptoms occurred in 4/67 (5.9%) of the participants in the SCTOT group and in 3/47 (6.3%) of the patients in the ICTOT group. Operating time was longer in patients with SCTOT compared to those with ICTOT. CONCLUSION: The results of the treatment with SCTOT are not inferior to the results of the treatment with ICTOT and other results reported in the literature.
