RESUMO

Background: Lifestyle factors significantly impact overall health. Our aim was to assess reproductive health awareness among patients who applied for emergency contraceptive pills. Methods: This present retrospective observational study between July 2021 and September 2021 is embedded in the MEEC (Motivation and Epidemiology of Emergency Contraceptive Pill) based on the study cohort of a Hungarian data bank containing follow-up data of 447 women who applied for EC telemedicine consultation. Collected data: age, history of previous pregnancy, lifestyle factors like smoking, alcohol consumption, sexual characteristics: partner consistency and protection during intercourse, cervical cancer screening within the past 2 years, previous HPV screening, and the preference for future contraceptive methods. The investigation also compiled accurate data on intercourse (elapsed time to request a medical consultation). Lifestyle factors were scored. Results: The more health-conscious patients were quicker to report for a post-event pill. Earlier pregnancies and older age were associated with greater reproductive health awareness. Conclusions: Reproductive health awareness is increased by previous pregnancies and older age. More health-conscious women consult a doctor earlier, which can reduce the chance of various health damage. Our study emphasizes the significance of lifestyle factor influence on reproductive health decisions.

RESUMO

INTRODUCTION: Emergency contraception is an effective and safe solution for preventing unwanted pregnancies. Many methods of emergency contraception are used, which have different mechanisms of action and time frames. OBJECTIVE: Providing information to healthcare professionals and decision-makers based on the literature data about the target populations of emergency contraception, evidence-based modern methods, their effectiveness, and practical application for the purpose of reducing the incidence of unintended pregnancies. METHODS: We conducted a systematic literature search in MEDLINE (PubMed), Embase and Scopus databases based on relevant keywords, for publications that were published between 1960 and 2023. RESULTS: 23 clinical professional publications were selected that examined the effectiveness of oral and long-term usable contraceptives as emergency contraceptives. Our research results were interpreted in terms of weight, breastfeeding, time elapsed since the intercourse and future contraceptive plans, which help to select the most appropriate emergency contraceptive for healthcare professionals. CONCLUSION: Based on the literature data, our systematic review provides assistance for choosing between the available oral levonorgestrel, ulipristal acetate, and intrauterine contraceptive devices available in Hungary based on effectiveness, target population, and accessibility. We support the healthcare governance in creating up-to-date professional guidelines to improve the availability of emergency contraception and, consequently, enhance reproductive health.

RESUMO

Lymph node (LN) status is the most significant prognostic factor for invasive urothelial bladder cancer (UBC); however, the optimal extent of LN dissection (LND) is debated. We assessed circulating matrix metalloproteinase-7 (MMP-7) as a prognostic factor and decision-making marker for the extent of LND. Preoperative serum MMP-7 levels were determined in two independent UBC cohorts (n = 188; n = 68) and in one control cohort (n = 97) by using the ELISA method. A systematic review and meta-analysis on the prognostic role of circulating pretreatment MMP-7 levels were performed. Serum MMP-7 levels were higher in patients compared to controls (p < 0.001) with the highest levels in LN-positive cases. Half of LN-positive UBC patients had low MMP-7 levels, whereas the survival of LN-negative patients with high serum MMP-7 findings was poor. MMP-7 levels were independently associated with poor survival in both cohorts (p = 0.006, p < 0.001). Accordingly, our systematic review of six eligible publications revealed a 2.5-fold higher mortality risk in patients with high MMP-7 levels. In conclusion, preoperative MMP-7 level is a validated and independent prognostic factor in urothelial cancer. It cannot be used to decide between regional or extended LND but may be useful in identifying LN-negative high-risk patients with potentially undetected metastases.

RESUMO

Urachal carcinoma is a rare malignancy that is uniquely associated with the field of urology. Urachal carcinoma is mostly diagnosed in urological care centers due to its most frequently presenting symptom that is hematuria. Currently available diagnostic and therapeutic knowledge is solely based on case reports and single center series, while no prospective clinical studies are carried out due to the modest number of patients. These circumstances have made creating professional guidelines challenging, hence the treatment of urachal carcinoma is commonly based on individual clinical decisions. In this review, we summarize the epidemiology, diagnostic modalities, prognosis as well as local and systemic therapeutic approaches of urachal carcinoma. Furthermore, we aim to draw conclusions from this knowledge base that may guide clinical decision-making. Finally, we highlight some of the novel therapeutic strategies that hold the potential to improve urachal carcinoma patients' prognosis and quality of life. Orv Hetil. 2023; 164(16): 602-609.

RESUMO

Introduction: Overactive bladder syndrome is an endemic phenomenon, which has a significant impact on the quality of life. In cases where conservative treatment fails, intradetrusor onabotulinumtoxinA injection can be used as second-line therapy. Objective: To assess the safety and efficacy of onabotulinumtoxinA treatment in the management of non-neurogenic detrusor overactivity among our patients. Also, to examine the influence of perioperative factors on the effects of the efficacy. Method: We have retrospectively collected the perioperative data of 33 patients treated with intradetrusor BOTOX®. The assessment of the efficacy and complications was done by the examination of patient files and questionnaires. The results obtained during the statistical analysis were considered significant for p<0.05. Results: We have not experienced notable complications after the procedures. Only 6 patients had residual urine (p = 0.024), none of them needed to be catheterized. We have observed significant decrease in the incidence of frequency, nocturia, urgency and incontinence, just as in the number of pads needed daily (p<0.01). Quality of life and general health were significantly improved (p<0.001). We have not found any significant connection between preoperative factors and efficacy (72.7%). Discussion: Our results considering the relief of symptoms are well in line with international data. The fact that our rate of complications is - in international comparison - outstanding can be explained by a more careful patient selection and thorough preoperative assessment. Conclusion: OnabotulinumtoxinA therapy is a safe and effective solution of therapy-refractory overactive bladder. We could not identify any perioperative factor to predict postoperative efficacy of therapy. Orv Hetil. 2021; 162(36): 1459-1465.

RESUMO

BACKGROUND: Voiding dysfunction (VD) is a potential complication after female midurethral sling operations. OBJECTIVES: Our goal was to assess the rate of obstructive VD after -transobturator tension-free tape (TOT) procedures and to find perioperative risk factors (RFs) predicting postoperative voiding problems. METHODS: We have retrospectively evaluated the perioperative data of 397 women who underwent TOT operations. Significant post-void residual (PVR) (>50 mL) was considered as the primary (objective) end point of the study, the voiding difficulty as the secondary (subjective) 1. First univariate analysis and then multivariate logistic regression were performed, with a 5% significance level. RESULTS: Significant PVR was present in 51 (12.8%) women; catheterization was needed in 21 (5.3%) and reoperation in 3 (0.8%) cases. Seventy women (17.6%) experienced postoperative voiding difficulty. Narrow vagina (<2 cm), older age >70 years, and preoperative voiding difficulty were independent RFs for significant PVR (odds ratio: 5.07, 2.14, 5.38, respectively, p < 0.05). Preoperative overactive bladder syndrome and previous pelvic organ prolapse surgery were considered independent RFs for postoperative voiding difficulty. CONCLUSIONS: Older age, narrow vagina, or preoperative voiding difficulty increases the chance for significant postoperative PVR. These patients should be chosen and counseled appropriately.

RESUMO

Local or systemic inflammation can severely impair urinary bladder functions and contribute to the development of voiding disorders in millions of people worldwide. Isoprostanes are inflammatory lipid mediators that are upregulated in the blood and urine by oxidative stress and may potentially induce detrusor overactivity. The aim of the present study was to investigate the effects and signal transduction of isoprostanes in human and murine urinary bladders in order to provide potential pharmacological targets in detrusor overactivity. Contraction force was measured with a myograph in murine and human urinary bladder smooth muscle (UBSM) ex vivo. Isoprostane 8-iso-PGE2 and 8-iso-PGF2α evoked dose-dependent contraction in the murine UBSM, which was abolished in mice deficient in the thromboxane prostanoid (TP) receptor. The responses remained unaltered after removal of the mucosa or incubation with tetrodotoxin. Smooth muscle-specific deletion of Gα12/13 protein or inhibition of Rho kinase by Y-27632 decreased the contractions. In Gαq/11-knockout mice, responses were reduced and in the presence of Y-27632 abolished completely. In human UBSM, the TP agonist U-46619 evoked dose-dependent contractions. Neither atropine nor the purinergic receptor antagonist pyridoxalphosphate-6-azophenyl-2',4'-disulfonic acid decreased the effect, indicating that TP receptors directly mediate detrusor muscle contraction. 8-iso-PGE2 and 8-iso-PGF2α evoked dose-dependent contraction in the human UBSM, and these responses were abolished by the TP antagonist SQ-29548 and were decreased by Y-27632. Our results indicate that isoprostanes evoke contraction in murine and human urinary bladders, an effect mediated by the TP receptor. The G12/13-Rho-Rho kinase pathway plays a significant role in mediating the contraction and therefore may be a potential therapeutic target in detrusor overactivity.NEW & NOTEWORTHY Voiding disorders affect millions of people worldwide.

RESUMO

Bradykinin (BK) has been proposed to modulate urinary bladder functions and implicated in the pathophysiology of detrusor overactivity. The present study aims to elucidate the signaling pathways of BK-induced detrusor muscle contraction, with the goal of better understanding the molecular regulation of micturition and identifying potential novel therapeutic targets of its disorders. Experiments have been carried out on bladders isolated from wild-type or genetically modified [smooth muscle-specific knockout (KO): Gαq/11-KO, Gα12/13-KO and constitutive KO: thromboxane prostanoid (TP) receptor-KO, cyclooxygenase-1 (COX-1)-KO] mice and on human bladder samples. Contractions of detrusor strips were measured by myography. Bradykinin induced concentration-dependent contractions in both murine and human bladders, which were independent of secondary release of acetylcholine, ATP, or prostanoid mediators. B2 receptor antagonist HOE-140 markedly diminished contractile responses in both species, whereas B1 receptor antagonist R-715 did not alter BK's effect. Consistently with these findings, pharmacological stimulation of B2 but not B1 receptors resembled the effect of BK. Interestingly, both Gαq/11- and Gα12/13-KO murine bladders showed reduced response to BK, indicating that simultaneous activation of both pathways is required for the contraction. Furthermore, the Rho-kinase (ROCK) inhibitor Y-27632 markedly decreased contractions in both murine and human bladders. Our results indicate that BK evokes contractions in murine and human bladders, acting primarily on B2 receptors. Gαq/11-coupled and Gα12/13-RhoA-ROCK signaling appear to mediate these contractions simultaneously. Inhibition of ROCK enzyme reduces the contractions in both species, identifying this enzyme, together with B2 receptor, as potential targets for treating voiding disorders.

RESUMO

PURPOSE: Significant post-prostatectomy incontinence (PPI) is a crippling condition and managed best through sling or artificial urinary sphincter (AUS) implantation. These procedures are often associated with complications requiring surgical intervention. The aim of our retrospective study was to evaluate the occurrence of major complications and identify risk factors. MATERIALS AND METHODS: Between 2010 and 2018 ninety-one patients have been implanted with sling (22; 24.2%) or AUS (69; 75.8%) in our department. The cases where surgical revision was needed were examined regarding the etiology (mechanical failure (MF), urethral erosion (UE), urethral atrophy (UA), surgical site infection (SSI), combined reasons (COMB) and analyzed, using 16 possible perioperative risk factors. RESULTS: Surgical intervention was carried out by 19 / 91 (20.9%) patients. (In 16 / 69 cases after AUS (23.1%), 3 / 13 after slings (23%)). The indication was in 6 (31.6%) cases MF, in 3 (15.8 %) COMB, in 4 (21.1%) UE, in 5 (26.3 %) SSI, in 1 (5.2%) UA. The type of reoperation was either explantation (12 / 19), system replacement (6 / 19), or cuff replacement (1 /19). Regarding the surgical intervention requiring complications only preoperative bacteriuria (P = .006) and postoperative surgical site oedema (P = .002) proved to be independent predictive factors. CONCLUSION: Preoperative bacteriuria and surgical site oedema seemed to be good predictors for obligate surgical revision. Patients with AUS were more prone to have major complications. In most cases it was mechanical failure, infection or erosion. By reducing the frequency of these risk factors we might be able to decrease the amount of complications.

RESUMO

OBJECTIVE: The majority of prostate cancers require androgen hormones for growth, and androgen ablation is an important part of the systemic treatment of advanced prostate cancer. Nevertheless, most of these cancers eventually relapse as they become less sensitive to androgen ablation and anti-androgen treatment. Elucidating the molecular events that are responsible for the conversion of androgen-sensitive cancers to androgen-refractory tumors may reveal new therapeutic opportunities. METHODS: In the present study, we investigated nine androgen-sensitive and nine androgen-refractory prostate cancer samples to evaluate the expression levels of 10 selected proteins that have been implicated in oncogenesis and cancer progression. RESULTS: Our immunohistochemical data show that three of the investigated proteins (i.e., minichromosome maintenance-2, methylguanine-DNA methyltransferase, and androgen receptor) are expressed at significantly different levels in the androgen-refractory cancer samples than in the androgen-sensitive tumors, whereas the expression levels of the seven other studied proteins (i.e., ß-catenin, p27, p21, p16, Ki67, hypoxia-inducible factor 1 alpha, and geminin) are not significantly different regarding the two groups. CONCLUSIONS: Our data suggest that the increased expression of minichromosome maintenance-2 and decreased expression of methylguanine-DNA methyltransferase related to androgen receptor are indicative of the androgen-refractory stage in prostate cancer. Further studies are required to determine whether these expression changes play a causative role in the transition of androgen-sensitive to androgen-refractory prostate cancer.

RESUMO

PURPOSE: The main objective of this retrospective study was to evaluate the influence of pathological experience in histological examination of prostate cancer (PCa) on preoperative understaging (UNS), undergrading (UNG), and upgrading (UPG). METHODS: Histopathological data of prostate biopsy (PB) and radical prostatectomy (RP) specimens of patients undergoing subsequent radical prostatectomy (n = 430) in our center were compared. Histological diagnoses of PB were provided either by corresponding academic pathology institute (Group 1: 322 patients) or by external (nonacademic) departments which had a lower number (≤ 100/year) of PCa histopathological evaluations (Group 2 108 patients). The rate of UNG, UPG, and UNS in both groups and also the effects of institutional learning curve were analyzed in terms of grading and staging. RESULTS: Significant difference was detected between Group 1 and Group 2 in average preoperative Gleason score (GS) values and in the rate of well, moderately, and poorly differentiated cancers as well. There was also a significant difference in the rate of UNG (29.1 vs. 56.5 %, p < 0.0001). The mean preoperative and postoperative GS in Group 1 was significantly lower in the first 50 than in the last 50 patients, but the rates of UNG, UPG, and UNS did not differ significantly between the groups. CONCLUSIONS: The experience of pathologists has direct influence on grading concordance and on UNG and UPG, between PB and RP specimen; however, it has no significant effect on complete preoperative understaging. The bigger pathological experience improves the sensitivity of the histological diagnostic process.

RESUMO

Radical prostatectomy is the curative surgical management of organ confined prostate cancer. Erectile dysfunction may follow surgery as the most common complication decreasing the quality of life of the patient. Thanks to spreading PSA screening probability increases to detect prostate cancer in its early stage and so the expected number of surgery is increasing, too. Higher number of operation as well as surgery more frequently performed in younger age calls the attention to the importance of erectile dysfunction and its management. Nowadays the physiology of erectile dysfunction due to radical prostatectomy has been revealed, and as a consequence, the nerve sparing surgery for its prevention is already known. The paper presents the different kind of possible invasive and non-invasive treatments of erectile dysfunction, and surveys their history and effectiveness. The erectile function of patients who underwent radical prostatectomy between 1998 and 2007 at the Department of Urology and Uro-oncological Centre was assessed by IIEF- and MMM questionnaire and letters with questions of habit of medicine taking. The results show that 59% of patients who desire sexual activity are capable of it spontaneously or with medical management.

RESUMO

The aim of our study was to find the cause of urinary incontinence and voiding dysfunction in patients undergoing radical cystectomy and orthotopic bladder replacement with modified ileal neobladder (Reddy). Twenty-eight incontinent patients (operated on between 1988 and 2004) were involved in our examination. Based on the complaints of the patients, continence status was evaluated and divided into two groups: group I: partially incontinent (only night-time incontinence) n = 11 (39.3%) and group II: totally incontinent (night-time and daytime incontinence) n = 17 (60.7%). Detailed urodynamic examination (enterocystometry and urethral pressure profile) in addition to involuntary neobladder contractions and capacity detection were carried out on all patients. Furthermore resting pressure and maximal voluntary contraction ability of the sphincter were determined and statistically analyzed in both groups. Significant difference was noticed in resting pressure and maximal voluntary contraction ability of the sphincter among the partially incontinent and totally incontinent patients. Frequency, intensity and duration of involuntary neobladder contractions also showed significant differences between the two groups. Incontinence of neobladder depends not only on the destruction of resting and contraction capability of the urethral sphincter, but also on the presence or absence of involuntary contractions in the wall of the neobladder and decreased capacity of the neobladder.

RESUMO

INTRODUCTION: Our aim was to identify the independent risk factors associated with urinary incontinence after radical retropubic prostatectomy (RRP). MATERIALS AND METHODS: Using univariate and multivariate analyses, we examined several pre- and perioperative factors. One hundred and sixty-six patients were divided into three groups: patients who were immediately continent after catheter removal (group I), patients who became continent later (group II) and incontinent patients (group III). RESULTS: There were 34 patients (20.5%) in group I, 111 (66.9%) in group II, and 21 (12.6%) in group III. The multivariate analysis between the continent and incontinent patients proved that the postoperatively measured total length of the posterior urethra (strongly associated with length of the sphincter, length of the urethral stump and the presence of anastomotic stricture) was the independent risk factor for permanent incontinence or delayed continence following RRP. The age of patients per se represented a risk factor only for delayed continence, but not for permanent incontinence. CONCLUSIONS: Postoperatively measured shorter posterior urethral length results in an increased risk of urinary incontinence and delays continence after RRP. It seems that older age only delays reaching continence.

RESUMO

INTRODUCTION: The tumour of the bladder is the third most frequent urological malignancy. Muscle invasive cancer can be cured by radical cystectomy. After removing the bladder; a sufficient urinary diversion should be performed. AIM AND METHOD: The authors introduce the operative process of the pouch and their experiences with the procedure. The analysis of results were performed retrospectively. RESULTS: Between 1998 and 2005 the authors performed radical cystectomy in 76 patients followed by: Mainz pouch II urinary diversion. The average age of the patients was 59.8 (20-78) years. The distribution by gender was: 58 male, 18 female patients. The average pathological T stage was 2.3; 22 patients (29%) had metastatic lymph nodes. 94% of the cases were transitional cell cancers, 3 (4%) of them had adenocarcinoma and one leiomyosarcoma. Reoperation was carried out in 7 cases (9.2%) because of wound healing defects, and one patient was reoperated because of bleeding and ileus respectively. Transitionally nephrostomy was performed in 5 cases (6.5%) because of upper urinary tract dilatation due to a stricture of ureter anastomosis. The average survival period was 24.4 (1-98) months. CONCLUSION: Urinary diversion Mainz pouch II provides for safe, continent diversion requiring no urine bag; with an acceptable QL (quality of life). On the basis of the low number of complications and the acceptable QL; the authors consider this method as appropriate.

RESUMO

AIMS: During this prospective study we analyzed the effects of radical retropubic prostatectomy (RRP) on bladder and sphincter function by comparing preoperative and postoperative urodynamic data. The aim of the study was to determine the reason for urinary incontinence after RRP and explain why one group of patients will be immediately continent after catheter removal, while others need some time to reach complete continence. METHODS: Urodynamic examination was performed in 63 patients 3-7 days before and 2 months after surgery. RESULTS: Forty-three (68.2%) and 53 (84.1%) patients regained continence at 2 and 9 months following RRP, respectively. Ten patients (15.9%) were immediately continent after catheter removal. Urodynamic stress incontinence was detected in 18 (28.6%), and detrusor overactivity incontinence in 2 (3.2%) patients 2 months after surgery. The amplitude of preoperative maximal voluntary sphincteric contractions was significantly higher in the postoperative continent group (125 vs. 96.5 cmH(2)O, P < 0.0001). The patients who were immediately continent following catheter removal had no lower urinary tract symptoms (LUTS) and urodynamic abnormality preoperatively, and they had significantly higher preoperative and postoperative maximum urethral closure pressure (at rest and during voluntary sphincter contraction) than those who became continent later on. CONCLUSIONS: These data suggest that the main cause of incontinence after RRP is sphincteric weakness. In the continent group, those who became immediately continent had significantly higher maximum urethral closure pressure values at rest and at voluntary sphincteric contraction even before the surgery.

RESUMO

INTRODUCTION: The two main reasons of stress incontinence, according to the present consensus, are urethral hypermotility due to descended bladder floor and intrinsic sphincter deficiency. Distinction between them used to be achieved by determining urethral pressure profile only. In recent years a less invasive method, measuring the Valsalva Leak Point Pressure, has been developed for a differentiation. AIMS: To determine Valsalva Leak Point Pressure using a simple technique for differential diagnosis of stress incontinence without a complete urodynamic test. METHOD: A minimally invasive technique is presented. Authors have performed parallel measurements of leak point pressure and urethral pressure profile during urodynamic examination in 43 stress incontinent patients. Difference in the results have also been evaluated. RESULTS: A specificity of 98% and a sensitivity of 51% with the method was found in intrinsic sphincter deficiency. In cases without vaginal descent the sensitivity was 100%, while in patients with urethral hypermobility the sensitivity and the specificity were 91% and 58% respectively. CONSEQUENCES: In stress incontinent patients without urethral hypermotility an abdominal leak point pressure of less than 40 H2O cm perfectly reflects weakness of the urethral sphincter. Based on these data we suggest that the invasive urethral pressure profile test can be avoided in appr. 20% of stress incontinence cases by weakness of the sphincter.
