RESUMO
INTRODUCTION AND HYPOTHESIS: Overactive bladder (OAB) and mixed urinary incontinence (MUI) are significant problems worldwide. Their broad definition makes them difficult to diagnose; therefore, specialists need a tool to confirm diagnosis. The Overactive Bladder Symptom Score (OABSS) is used in the objective diagnosis of OAB. We aimed to develop and evaluate the effectiveness of OABSS for patients in Poland suffering from OAB and MUI and to correlate it with UDI-6 and IIQ-7. METHODS: A total of 824 women suffering from urinary incontinence (UI) aged between 18 and 75 years were included. SUI (n = 290); OAB (n = 285) and MUI (n = 249) were confirmed by medical history and urodynamic study. Of the subjects, 821 women completed the Polish version of OABSS on two separate visits: weeks 0 and 2. In addition, they undertook UDI-6 and IIQ-7 during Week 2. The Cronbach's alpha (α) was used to estimate the internal consistency. Scores were compared using the intraclass correlation coefficient (ICC). RESULTS: We observed statistically significant differences (p < 0.0005) between mean scores of OABSS among patients from the study groups OAB-SUI and MUI-SUI. We did not observe statistically significant differences between patients from the MUI and OAB groups (p > 0.11). Analysis also did not show statistically significant differences between visits. The internal consistency was very good: α = 0.89 (SUI); = 0.9 (OAB); = 0.82 (MUI). In all groups, test-retest reliability was excellent; ICC was >0.99. CONCLUSIONS: The Polish version of the OABSS is a reliable tool for females suffering from UI. However, OABSS does not distinguish patients with MUI from patients with OAB.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to assess the efficacy of duloxetine in an animal model of detrusor overactivity induced by depression. METHODS: After 6 weeks of 13-cis-retinoic acid administration at a dose of 1 mg/kg/day, rats were given duloxetine at a dose of 1 mg/kg. This was followed by conscious cystometry, a forced swim test, and locomotor activity measurement. The levels of corticotropin-releasing factor (CRF) in the hypothalamus, amygdala and plasma were also determined. RESULTS: Duloxetine treatment led to a reduction in detrusor overactivity symptoms induced by the retinoid. Decreases were observed in cystometric parameters including the detrusor overactivity index, and the amplitude and frequency of nonvoiding contractions, while increases were seen in bladder compliance and the volume threshold to elicit nonvoiding contractions. No statistically significant differences were found in basal pressure, threshold pressure, micturition voiding pressure, postvoid residual , volume threshold, voiding efficiency, intercontraction interval, bladder contraction duration or relaxation time. Duloxetine also reduced the immobility time to that observed in control animals, while it did not affect locomotor activity. Its effects also included lowering of the CRF levels in the hypothalamus, amygdala and plasma, which increased following the prior administration of the retinoid. The plasma level of 13-cis-retinoic acid in rats corresponded to the levels found in humans. CONCLUSIONS: This is the first study showing the efficacy of duloxetine in an animal model of detrusor overactivity induced by depression. Further studies in patients with detrusor overactivity and coexisting depression are warranted to confirm these experimental results.

INTRODUCTION AND HYPOTHESIS: Midurethral sling (MUS) surgeries are minimally invasive procedures; however, they are not free of postoperative complications. The aim of the study was to assess the occurrence of lower urinary tract symptoms (LUTS) (urgency, nocturia, frequency, splitting/spraying, hesitancy, terminal dribbling, and subjective feeling of postvoid residual) in patients suffering from stress (SUI) or mixed (MUI) urinary incontinence with a predominant SUI component before and after transobturator MUS placement. METHODS: The study group consisted of 88 women with SUI and 18 with MUI who underwent transobturator MUS. All participants were questioned with a self-developed questionnaire before and after surgery regarding the presence of LUTS. RESULTS: Seven days after surgery, 62 patients (58.5%) noted voiding and postmicturition symptoms, whereas 67 (63.2%) reported problems in storage. The more commonly reported LUTS at week 1 after surgery were urgency (52.8%), splitting/spraying (41.5%), and feeling of incomplete bladder emptying (34.0%). Patients perceived that splitting/spraying was the most bothersome. After 6 months, the most common LUTS reported were hesitancy (14.1%), terminal dribbling (10.4%), and splitting/spraying (9.4%). We noticed a decrease in the number of urgency episodes >2.7 times (p < 0.001) compared with baseline. After 6 months, 97 (91.5%) patients reported the lack of incontinence episodes. CONCLUSIONS: A vast majority of patients after MUS suffer from LUTS in the early postoperative period; however, the majority of undesired symptoms resolve spontaneously within the first 6 months postsurgery.

OBJECTIVES: Due to prolonged life expectancy, regardless of the fact that elderly women are more likely to suffer from comorbidities, urogynaecologists worldwide should expect a growing demand for counseling and effective treatment for patients with pelvic floor defects. The aim of the study was to investigate the incidence of popular comorbidities among urogynaecological patients. MATERIAL AND METHODS: The retrospective analysis included clinical data of 4,065 consecutive female patients who under-went surgical treatment in the 2nd Department of Gynaecology at the Medical University of Lublin due to urogynaecological disorders between January 2005 and December 2014. Patients were divided into two groups (< 65 years and ≥ 65 years). The vast majority of patients affected by stress urinary incontinence were treated with mid-urethral slings. Most of patients affected by pelvic organ prolapse underwent reconstructive vaginal surgery with reinforcement using anterior and/or pos-terior meshes. Statistical analysis was performed using STATISTICA 10.0 PL (unpaired Student t-test, U Mann Whitney, χ2 test). RESULTS: In both study groups, overweight and obesity were the most common disorders affecting urogynaecological patients (72.6% overall). Furthermore, the elderly patients suffered more often from the most common comorbidities, such as hypertension (p < 0.01), coronary artery disease (p < 0.001) and diabetes mellitus (p < 0.005). CONCLUSIONS: Common comorbidities such as overweight and obesity, followed by hypertension and coronary heart diseases, are usual among urogynaecological patients. Changes in lifestyle leading to a decrease in obesity should be considered as an important line treatment when counselling urogynaecological patients.

Objectives: The aim of the study was to assess the effect of different types of hysterectomy on the development of postoperative urinary incontinence (UI). Materials and Methods: The study group consisted of 392 women who underwent supracervical laparoscopic hysterectomy (SLH), total abdominal hysterectomy (TAH), supervical abdominal hysterectomy (SH), or vaginal hysterectomy (VH) for benign indications 2010 and 2013. The patients reported no UI-related complaints before surgery. UI status was assessed 12 months postoperatively using the cough test and the 24-hour pad test. Results: UI developed within 12 months after surgery in 149 (38%) out of 392 women. No statistically significant correlation between the type of treatment and UI incidence was detected. The percentage of patients affected by UI did not differ between the study groups. Conclusions: Hysterectomy constitutes a risk factor for the development of urinary incontinence but the occurrence of postoperative UI does not depend on the type of surgery.

OBJECTIVES: Minimally invasive gynaecological surgeries are performed for several malignant and nonmalignant indications. The aim of our study was to evaluate the rate of unexpected malignancies among women who underwent laparoscopical supracervical hysterectomy (LASH) with power morcellation. MATERIAL AND METHODS: The retrospective analysis included clinical data of 426 consecutive female patients who underwent LASH with power morcellation due to presumed benign disorders (78.4% - symptomatic uterine fibromas, 12.7% - abnormal uterine bleeding, 8.9% - suspicion of uterine adenomyosis) between January 2011 and December 2015. Pre-malignant or malignant preoperative abnormalities in the cervix and the uterine corpus were contraindications for LASH. RESULTS: The unexpected malignancies were found in four patients from study group: one ovarian cancer located on the inner part of simple ovarian cyst and 3 endometrial carcinomas (0.9%) were documented. All these patients underwent abdominal reoperations and no histological abnormalities were detected in the extirpated cervix and adnexa. CONCLUSIONS: The incidence of unintended endometrial carcinoma in morcellated uterus after LASH was relatively small. However, careful pre-operative counseling should be undertaken in order to exclude the possibility of any malignant disease in uteri among women scheduled to power morcellation.

INTRODUCTION: Malignant tumors are rarely diagnosed during pregnancy and their incidence ranges from 2.4% to 5.7%. Ovarian cancer is ranked fifth among all cancer types and second among all genital cancers diagnosed during pregnancy The course of the disease is asymptomatic in most cases and the initial diagnose is typically made during a routine ultrasound examination. Management of ovarian cancer during pregnancy presents a considerable challenge due to the absence of clear standards of treatment. OBJECTIVES: We present three clinical cases of patients suffering from ovarian cancer diagnosed during pregnancy a review of the literature, as well as possible therapeutic options. RESULTS: Three different clinical scenarios in patients with ovarian cancer diagnosed during pregnancy have been presented. In addition, we reviewed current diagnostic and therapeutic algorithms for patients with ovarian cancer and co-existing pregnancy. CONCLUSIONS: Approximately 5% of ovarian tumors diagnosed in pregnancy are malignant. There are no treatment standards for ovarian cancer diagnosed during pregnancy. Surgical treatment and the subsequent chemotherapy in the 2nd trimester of pregnancy appear to be safe for both, the mother and the child. However, the potential risks and benefits associated with the treatment have to be thoroughly analyzed on a case-by-case basis, to establish optimal diagnostic and treatment algorithms.

Stress urinary incontinence (SUI) is a common condition that affect 30-40% of women in their lifetime. Midurethral slings (MUS) either suprapubic or transobturator can be safely used in the surgical treatment of SUI. The aim of this study was to collect clinical long-term data regarding safety and performance of transobturator sling with an additional tape fixation in women with urinary incontinence. This prospective longitudinal study was conducted on a group of 2086 female patients diagnosed with stress urinary incontinence. Follow up visits where scheduled 6 weeks, 6 and 12 months after surgery followed by annual checking when possible. Patients underwent transobturator sling procedure from 01.01.2011 to 31.12.2021. All patients had a monofilament tape inserted at the mid-urethra using outside-in technique (TOT) with 2 absorbable sutures parallel to the urethra. Success of surgery was defined as lack of any leakage during cough stress test whereas the subjective cure rate was determined by Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-SF). 87% of patients who were operated at least 10 years before assessment reported ICIQ -SF < 6. Main postoperative complications were storage symptoms - de novo urgency and voiding difficulties. TOT is safe and highly effective surgical treatment for (SUI) in a long-term observation.

OBJECTIVE: Urinary tract infection (UTI) is relatively common post-operative complication following midurethral sling placement (MUS), even in cases where intraoperative antibiotic prophylaxis was given. The primary aim of this study was to investigate the non-inferiority of Femistina as compared with Canephron in reducing symptomatic UTI in first six months following surgery. STUDY DESIGN: A sample size of 144 patients per group was established, to provide at least 90% power to demonstrate the non-inferiority of phytodrug Femistina versus Canephron as a prevention of post-MUS urinary tract infection. RESULTS: Women suffering from stress urinary incontinence and mixed urinary incontinence (MUI) with predominant SUI symptoms as confirmed by urodymamics (n = 320) were randomized in a 1:1 ratio to Femistina (40 mg, oral, twice daily for 20 days) or Canephron (3 × 5 ml taken orally-three times daily for 4 weeks). Both groups were homogenous for age, type of operation (only TOT outside-in) and severity of illness as indicated by ICIQ-SF questionnaire. We found that symptoms of UTI were significantly lower in patients receiving Femistina. During first 6 months after surgery UTI was confirmed in only 10 patients receiving Femistina (6,25%) when compared to 25 (15,63%) subjects receiving Canephron, p < 0.007. CONCLUSION: Femistina is not inferior to Canephron in preventing lower urinary tract infection after midurethral sling surgery.

Urinary tract infections (UTIs) are one of the most common reasons for antibiotic prescriptions among women worldwide. UTIs are also associated with intra- and postoperative catheterization, which is an essential component of many gynecological surgical procedures, including midurethral sling (MUS) placement. The aim of this study was to compare the incidence of UTI subsequent to a MUS procedure. The study involved 562 female patients who underwent MUS procedures due to stress urinary incontinence (SUI). Patients were assigned in a 1:1 ratio to two study groups: patients receiving 500 mg of ciprofloxacin three times a day for 3 consecutive days after surgery or patients receiving 5 mL of Canephron taken orally three times a day for 3 weeks. After analyzing the collected data, it was found that in the group of patients receiving ciprofloxacin, 29 women (10.98%) had a UTI, whereas in the group of patients receiving Canephron, 36 women (13.64%) had a UTI within 6 months after the patient's MUS procedure. No statistically significant difference between the two groups was noted. Postoperative prophylaxis with a phytodrug can be perceived as an attractive option in the reduction of antibiotic consumption among female patients after a MUS procedure.
RESUMO
OBJECTIVE: Advanced vaginal vault prolapse (VVP) can occur rarely after any type of hysterectomy. Several types of procedures have been applied to correct this defect, but optimal management is still pending. The aim of this study was to describe the surgical technique and results of four-arm transvaginal mesh (FATVM) application for advanced VVP. STUDY DESIGN: We followed up for 24 months, 160 patients with VVPâ¯>â¯II vc (according to the Pelvic Organ Prolapse Quantification Scale (POPQ)), who underwent FAMTVM from 2014 to2017. FAMTVM was inserted with the anterior arms through the obturator foramens and the posterior arms through the ischiorectal fossas and sacrospinal ligaments. Clinical data were prospectively collected in a customized database and retrospectively analyzed. To assess QoL SF 36, KHQ and FSFI questionnaires were used. POPQ was employed to measure degree of VVP. Non-parametric tests (The Wilcoxon signed-rank test) were applied to verify statistical hypotheses. RESULTS: According to SF 36, significant improvement was evident in almost all aspects of general QoL (PCS pâ¯=â¯0.002, MCS pâ¯=â¯0.01). KHQ showed statistically significant improvement in all domains. FSFI scores after surgery indicated significantly improvement in all domains of the questionnaire, apart from lubrication (pâ¯=â¯0.02). Intraoperative bladder injury occurred in 3.75 % (nâ¯=â¯6) of all cases. Five patients (3.1 %) complained of de novo stress urinary incontinence. VVP reoccurred in nine cases (5.6 %). Only two patients (1.25 %) saw mesh exposure after 6 months postoperative recovery. CONCLUSION: We consider FAMTVM for VVP to be safe and effective. Hence, it applied as an optional treatment, especially in patients with contraindications to laparotomy and laparoscopy.

The aim of this study was to assess the effectiveness of vaginal native tissue repair (VNTR) on preexisting Lower Urinary Tract Symptoms (LUTS) in women with symptomatic pelvic organ prolapse (POP). Two hundred patients who underwent VNTR for symptomatic POP from January 2018 to February 2019 were followed up for 6 months. All patients underwent VNTR, but in the posterior compartment, the rectovaginal fascia was reconnected to the uterosacral ligaments and additionally sutured to the iliococcygeus fascia and muscle. To assess the severity and change in storage phase LUTS before and after surgery, all participants were asked to complete 3 questionnaires: the International Consultation on Incontinence Questionnaire- Short Form (ICIQ-SF), Urogenital Distress Inventory-6 (UDI-6), and Incontinence Impact Questionnaire-7 (IIQ-7). The data were assessed with Statistica package version 12.0, using Kalmogorow-Smirnoff, W Shapiro-Wilk tests. Furthermore, one-way analysis of variance was applied with post-hoc Tukey test. The study results indicate that the majority of patients with advanced POP suffered from various LUTS. Among storage symptoms, the occurrence of urinary incontinence (UI) and urgency decreased significantly after surgery. Moreover, ICIQ-SF, UDI-6, and IIQ-7 results showed statistically significant improvement in the impact of UI on the quality of life (QoL) in the vast majority of patients after surgery. VNTR is an effective way to treat not only anatomical, but also functional problems in such patients.
RESUMO
Pelvic organ prolapse (POP) and the associated functional disorders are a major epidemiological problem that compromises the quality of life (QoL). The aim of this study was to assess the impact of lower urinary tract symptoms (LUTS) related to POP and vaginal native tissue repair (VNTR) on QoL. Two hundred patients with symptomatic POP were stratified into four groups according to the dominant storage phase function disorders: Urgency; stress urinary incontinence (SUI); mixed urinary incontinence (MUI), and without clinically significant symptoms from lower urinary tract (LUT). They underwent VNTR from January 2018 to February 2019. After 12 months, the QoL was assessed by the Prolapse Quality of Life (P-QoL) and visual analogue scale (VAS) questionnaires. The data were analyzed with Statistica package version 12.0 (StatSoft, Krakow, Poland), using the Kalmogorow-Smirnoff, Shapiro-Wilk W and the one-way analysis of variance with post hoc Tukey tests. The results of P-QoL showed significant improvement (p < 0.05) in all the study groups in most domains assessed before surgery and 12 months after surgery. Significant improvements in all the symptoms assessed by the VAS scale results were found in groups Urgency and MUI. The LUTS questionnaire revealed significant improvement in all voiding and post voiding symptoms in these groups. VNTR effectively eliminated LUTS and significantly improved the patients' QoL associated with POP.
RESUMO
AIM: Lower urinary tract symptoms (LUTS) frequently affect patients immediately after midurethral sling (MUS) placement. The objective of the study was to assess if solifenacin or mirabegron decreases incidence of LUTS in women who underwent transobturator MUS. METHODS: A prospective randomized trial was conducted on patients undergoing ambulatory transobturator midurethral sling due to stress urinary incontinence (SUI). All participants were questioned before and after surgery for occurrence of bothersome LUTS. A total of 328 patients who underwent transobturator MUS were randomly assigned to one of three groups: prophylaxis with 10 mg of solifenacin, prophylaxis with 50 mg of mirabegron, or without any additional treatment. LUTS evolution and efficacy of solifenacin and mirabegron were analyzed based on results of assessments made during follow-up visits at 1 and 6 weeks after surgery. Comparison of the prevalence of LUTS was done using chi2 test. RESULTS: Prevalence of urgency and frequency episodes increased notably 1 week after sling placement and then came down to baseline levels. Solifenacin and mirabegron significantly reduced the incidence of urgency after 1 week, but after 6 weeks the beneficial effect was observed only in case of solifenacin. Treatment with mirabegron reduced the percentage of patients suffering from frequency after 6 weeks. Although prevalence of nocturia did not raise after sling placement, both treatments significantly reduced the incidence of this complaint after 6 weeks. Pharmacological treatment did not modulate the course of hesitancy and terminal dribbling. CONCLUSIONS: Treatment with solifenacin or mirabegron may significantly reduce the incidence of undesired LUTS after MUS.

The aims of the study were to determine the effectiveness of blebbistatin (BLEB) on detrusor overactivity (DO) in an animal model induced by retinyl acetate (RA) and, because of potential urothelial permeability, to evaluate the degenerative impact of BLEB on the urothelium. Three days after RA instillation into the urinary bladder, BLEB was administered into the bladder and immediately after cystometric assessment was performed. Furthermore, Evans Blue extravasation into bladder tissue and urothelium thickness were measured. Sixty female Wistar rats were used and randomly assigned to one of four groups (n = 15 in each group): (1) control, (2) RA, (3) BLEB, and (4) RA + BLEB. RA administration induced changes in cystometric parameters reflecting DO, as previously reported. Treatment with BLEB did not significantly alter cystometric parameters in rats which did not receive RA. Administration of BLEB to rats pretreated with RA reversed changes in cystometric parameters induced by RA in basal pressure, threshold pressure, detrusor overactivity index, amplitude of nonvoiding contractions, frequency of nonvoiding contractions, voided volume, volume threshold, intercontraction interval, bladder compliance, and volume threshold to elicit nonvoiding contractions. There were no significant differences in Evans Blue extravasation into bladder tissue or urothelium thickness between the groups. The current research provides new data on the possible utility of blebbistatin in the pharmacotherapy of DO, which is an important feature of overactive bladder (OAB). Further studies in human patients with DO/OAB are warranted to confirm these preclinical results.

Overactive bladder (OAB) coexists with depression in women. Here, we assessed the effects of a 1-week treatment with blebbistatin, a myosin II inhibitor, on changes in behavior and detrusor overactivity (DO) symptoms induced by a 6-week administration of 13-cis-retinoic acid (13-cis-RA), with the aid of the forced swim test (FST), spontaneous locomotor activity test, and in vivo cystometric investigations in female Wistar rats. 13-cis-RA-induced depressive-like behavior and DO symptoms were associated with increased corticotropin-releasing factor (CRF) level in the plasma, prefrontal cortex (PFC), hippocampus (Hp), Barrington's nucleus (BN), and urinary bladder. Moreover, 13-cis-RA decreased brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) levels in plasma, PFC, Hp, and BN, while it increased BDNF and NGF levels in urinary bladder. Blebbistatin exerted antidepressant-like effect and attenuated changes in the cystometric parameters as well as the central and peripheral levels of CRF, BDNF, and NGF that were induced by 13-cis-RA, while it did not affect urine production, mean, systolic or diastolic blood pressure, or heart rate. The results point to blebbistatin as a potential treatment option for OAB coexisting with depression.

Literature data give clear evidence that upregulated RhoA/Rho-kinase signalling is one of the factors that may lead to the development of detrusor overactivity and various disorders of the central nervous system. Therefore, the main objective of our study was to investigate whether administration of a Rho-kinase inhibitor - GSK 269962 could reverse corticosterone-induced depressive-like behaviour and changes in cystometric parameters associated with detrusor overactivity, as well as undo the alterations of several biomarkers related to both disorders (i.e., pro-inflammatory/anti-inflammatory cytokines and neurotrophins) in serum, urinary bladder, and different brain structures. The experiments were carried out on female Wistar rats. Surgical procedures, cystometric investigations, biochemical analyses, and behavioural studies (measurement of the locomotor activity and the forced swim test) were performed according to the published literature. As expected, administration of corticosterone at a daily dose of 20â¯mg/kg for 14 days increased the immobility time of animals in the forced swim test, induced changes in the cystometric parameters specific to bladder overactivity, reduced levels of neurotrophins, and elevated concentrations of the pro-inflammatory cytokines. Inhibition of Rho-kinase by 7-day treatment with GSK 269962 (10â¯mg/kg/day) reversed the symptoms of both detrusor overactivity and depression as well as normalized levels of the tested biomarkes. Our findings encourage the idea of Rho-kinase inhibitors as a potential future treatment option for overactive bladder accompanied by depression.

Overactive bladder (OAB) often co-exists with depression in women. The corticotropin-releasing factor (CRF) system participates in the pathophysiology of both disorders. Therefore, we tested the effects of acute treatment with a reversible CRF receptor type-1 (CRF1) antagonist, SN003 (1mg/kg, i.v.), representatives of first (solifenacin, 0.03mg/kg, i.v.) and second (mirabegron, 1mg/kg, i.v.) line treatments for OAB as well as an antidepressant imipramine (30mg/kg, i.p.) on changes in depressive-like behavior and detrusor overactivity (DO) symptoms induced by a 6-week administration of 13-cis-retinoic acid (13-cis-RA, 1mg/kg/day, i.p.) in female Wistar rats, using in vivo cystometric investigations, forced swim test (FST) and spontaneous locomotor activity test. Following cystometric and behavioral studies, tissue was harvested and CRF level was assessed in the hypothalamus, amygdala and plasma. 13-cis-RA-induced depressive-like behavior and DO symptoms were associated with increased CRF levels in the hypothalamus, amygdala and plasma. Solifenacin and mirabegron attenuated DO symptoms induced by 13-cis-RA, did not display antidepressant-like activity and did not influence CRF levels in brain tissues or plasma. Imipramine and SN003 displayed antidepressant-like activity and lowered increased levels of CRF in brain tissues and plasma. Imipramine attenuated changes in some of the cystometric parameters, which are associated with OAB dry (without urge incontinence), whereas SN003 attenuated changes in almost all cystometric parameters that were induced by 13-cis-RA. CRF1 antagonist may be beneficial in case of OAB wet (with urge incontinence) or dry co-existing with depression. The possible mechanism may be related to the effects on central/peripheral CRF system.

Aim. Urinary tract infection (UTI) is considered one of the most common bacterial infections in women. The aim of this study was to investigate the types of uropathogens present, as well as the degree of antimicrobial drug resistance seen among premenopausal (n = 2748) and postmenopausal (n = 1705) women with uncomplicated UTI. Methods. Urinary samples (n = 4453) collected from women with UTI were analyzed in terms of uropathogens present. These were considered as positive if bacterial growth was ≥105 colony forming units (CFUs)/mL. Susceptibility and resistance testing for commonly used antibiotics was subsequently assessed. Results. The most common uropathogens cultured from urine samples were Escherichia coli (65.5%), followed by Enterococcus faecalis (12.2%), Klebsiella pneumoniae (4.7%), and Proteus mirabilis (4.2%). The resistance to ampicillin exceeded 40%, independently of menopausal status. Of note, resistance to ciprofloxacin exceeded 25% among postmenopausal patients. Moreover, resistance of all uropathogens to commonly used antimicrobials was significantly higher in postmenopausal women. Conclusion. Due to the high resistance rate, ampicillin, ciprofloxacin, and the trimethoprim/sulfamethoxazole combination should be avoided in treating postmenopausal women affected by UTI without being indicated by initial urine culture report. Finally, cephalexin and cefuroxime are promising alternatives as initial treatment in postmenopausal women.
