Introduction and hypothesis: The aim of this study was to cross-culturally adapt and validate the Serbian version of the Australian pelvic floor questionnaire.; Methods: The Australian pelvic floor questionnaire was translated according to the standard method of back-translation. Women who presented with pelvic floor disorders completed the Serbian version of the Australian pelvic floor questionnaire. Women were subjected to clinical and gynecological assessment including physical examination, cough stress test, pelvic prolapse anatomical assessment using the Pelvic Organ Prolapse Quantification system, and post-void residual volume. Reliability and divergent validity was performed on 76 patients with significant pelvic floor dysfunction and 23 women without pelvic floor dysfunction. Patients repeated the questionnaire after 4 weeks.; Results: High reliability was observed in all four dimensions (Cronbach’s alpha coefficients were above 0.8 for each dimension: bladder 0.846, bowel 0.822, prolapse 0.842, and sexual function 0.823). Test-retest analyses revealed high reproducibility (intraclass correlation coefficients were above 0.9). Prolapse symptom score correlated significantly with pelvic organ quantification and bladder score correlated significantly with the results of the cough stress test (convergent validity). Scores distinguished between patients with pelvic floor disorders and controls (high discriminant validity).; Conclusions: The Serbian version of the Australian pelvic floor questionnaire is a reliable and valid instrument for assessment of quality of life in women with pelvic floor disorders. © 2014, The International Urogynecological Association.

Introduction/Aim. Glycosaminoglycans (GAG) are one of the main constituents of the connective tissue and cellular membrane. Their presence has been evidenced in mucosa and muscular tissue of the urinary bladder of both healthy individuals and those affected by carcinoma. This suggest their potential role in the onset of bladder carcinoma and follow-up of those patients. The aim of the study was to determine GAG levels in tumor tissue and the surrounding bladder mucosa in patients with bladder tumor, as well as in the bladder mucosa in patients with bladder carcinoma, and to compare the results according to the grade and stage of tumor and relapse. Methods. Tissue samples were taken in 61 patients (48 males and 13 females), mean age 61.5 years, range 40-92 years, obtained by transurethral resection (TUR) of bladder tumor, and 8 healthy persons. Determination of a total GAG content in the tissue samples was done by the Whiteman's method and then compared regarding the tumor grade and stage. Results. Tumor grade and stage directly correlated with the levels of GAG. The GAG levels were significantly higher in tumor samples as compared to healthy mucosa. Conclusion. Higher GAG levels were recorded in all the patients with bladder tumors comparing to smples obtained from healthy individuals. GAG levels do not predict tumor relapse.

Summary Objective Data pertaining to whether stress-induced aldosterone release is associated with cardiac disorders are lacking. This study was designed to compare whether the modulation of intra-operative aldosterone release by epidural analgesia had an effect on the brain natriuretic peptide (BNP) levels. Design, Patients, Measurements A study was pilot prospective, open label randomized one. Patients were randomized to one of two anaesthesia protocols: group 1 included 13 patients who received general anaesthesia, and group 2 included 12 patients who received combined general anaesthesia and epidural analgesia. Study protocol was by completed 25 male patients, median age 56 years, without significant comorbidities, who underwent radical cystectomy because of urinary bladder tumour. Serum aldosterone, BNP, cortisol (measured by radioimmunoassay), adrenocorticotropine hormone (ACTH) (by solid-phase ELSA), blood chemistry, complete blood count and vital signs were compared preoperatively, intra-operatively and at postoperative days (POD) 1 and 7. Results Hemodynamics was stable in both groups. Group 1 showed threefold serum aldosterone, (P = 0·001) 20-fold ACTH (P = 0·003) and twofold cortisol (P = 0·001) increases intra-operatively, unlike group 2. Both groups had a twofold BNP increase in POD 1 that remained above normal on POD 7 only in group 1 (P = 0·02; P = 0·019 vs group 2). Conclusion Alleviation of aldosterone release by epidural analgesia modulated the postoperative serum BNP pattern in patients with a low risk for cardiac diseases who underwent noncardiac surgery. © 2011 Blackwell Publishing Ltd.

In recent years, the focus of numerous studies has been the predictive value of inflammatory and nutritional parameters in oncology patients. The aim of our study was to examine the relationship between the inflammatory and nutritional parameters and the histopathological characteristics of patients with bladder cancer. A retrospective study included 491 patients who underwent radical cystectomy for bladder cancer between 2017 and 2021. We calculated the preoperative values of the neutrophil-to-lymphocyte ratio (NLR), the derived neutrophil-to-lymphocyte ratio (dNLR), the systemic immune-inflammation index (SII), the systemic inflammatory response index (SIRI), the platelet-to-lymphocyte ratio (PLR), the lymphocyte-to-monocyte ratio (LMR), the prognostic nutritional index (PNI), and the geriatric nutritional risk index (GNRI). Statistically significant positive correlations were observed between NLR, dNLR, SII, SIRI, and PLR and the pathological stage of the tumor. We observed statistically significant inverse correlations for LMR, PNI, and GNRI with the tumor stage. SIRI was identified as an independent predictor of the presence of LVI. dNLR was identified as an independent predictor of positive surgical margins. GNRI was identified as an independent predictor of the presence of metastases in the lymph nodes. We noticed the predictive value of SIRI, dNLR, and GNRI in the pathology of bladder cancer patients. © 2023 by the authors.

Background and Objective: To assess the oncologic and functional outcomes of testicular sparing surgery (TSS) based on a single institution experience. Methods: Forty-one patients with bilateral and 3 patients with solitary testicle tumors were referred to our institution. The inclusion criteria for TSS were normal serum testosterone levels, and tumor size (<2 cm). Sperm analysis and hormone status evaluation were performed preoperatively and postoperatively. None of the patients underwent local radiation therapy following TSS for reasons of fertility preservation. Results: A total of 26 TSS were performed in 24 patients. The median follow-up period was 51.0 months. Seven patients developed local recurrence, of which 5 had TIN and were subjected to radical orchiectomy, whereas re-do TSS was done in remaining 2 patients. The overall survival of the study group was 100%, and the presence of testicular intraepithelial neoplasia (TIN) was associated with worse recurrence-free survival (P = 0.031, log-rank). Testosterone values were normal in all of the patients, while 4 patients achieved conception. Conclusions: TSS is acceptable from an oncological point of view, and it enables continuation of a patient's life without lifelong hormonal substitution. Additionally, local irradiation therapy could be delayed in patients with TIN who wish to father children, but with high local recurrence rate. © 2014 Wiley Periodicals, Inc.

Introduction and hypothesis: Urinary incontinence (UI) and pelvic organ prolapse (POP) significantly decrease quality of life and sexual health. This study aimed to evaluate the reliability and validity of a Serbian adaptation of the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) used in assessing sexual function in women with UI and/or POP. Methods: This study included 416 women, 310 (74.5%) with UI and/or POP and 106 (25.5%) without UI and/or POP. The adaptation of the PISQ-12 to Serbian language was performed via back-translation. The content validity of the questionnaire was conducted by experts in the field. The reliability and validity of the PISQ-12 were analyzed. Evaluation of the data was performed using Content Validity Index (CVI), Cronbach’s alpha, test-retest reliability, item total correlation and confirmatory factor analysis. Results: Content validity of the Serbian PISQ-12 was 1.00 (100%). Item total correlations were between 0.459 and 0.819 (P < 0.001). The PISQ-12 had an adequate and high internal consistency (Cronbach’s alpha 0.806) as well as high test-retest reliability (Pearson correlation coefficient r = 0.807; P < 0.001). Factor analysis results revealed strong construct validity. The mean scores of PISQ-12 were significantly better in the control group compared with the women with UI and/or POP. Sexual function was negatively affected by UI and/or POP as assessed with SF-36 and I-QoL questionnaires. Conclusions: This study showed that the Serbian version of the PISQ-12 is a reliable, consistent, valid and condition-specific instrument to assess sexual function in women with UI and/or POP. © 2022, The International Urogynecological Association.
