Item Can We Predict the Surgical Margin Positivity in Patients Treated with Radical Prostatectomy? A Multicenter Cohort of Turkish Association of Uro-Oncology(GALENOS YAYINCILIK, 2015-01-01) Bolat, Deniz; Eskicorapci, Saadettin; Karabulut, Erdem; Baltaci, Sumer; Yildirim, Asif; Sozen, Sinan; Ates, Ferhat; Sekerci, Cagri Akin; Kurtulus, Fatih; Dirim, Ayhan; Muezzioglu, Talha; Can, Cavit; Bozlu, Murat; Gemalmaz, Hakan; Ekici, Sinan; Ozen, Haluk; Turkeri, LeventObjective To analyze the parameters that predict the surgical margin positivity after radical prostatectomy for localized prostate cancer. Materials and Methods In this multicenter study, the data of 1607 consecutive patients undergoing radical prostatectomy for localized prostate cancer in 12 different clinics in Turkey between 1993-2011 were assessed. Patients who had neoadjuvant treatment were excluded. We assessed the relationship between potential predictive factors and surgical margin status after radical prostatectomy such as age, cancer characteristics, history of transurethral prostate resection, surgical experience and nerve-sparing technique by using univariate and multivariate Cox regression analyses and t test. Results The overall surgical margin positivity rate was 22.6\% (359 patients). In univariate analyses, preoperative prostate specific antigen level, clinical stage, biopsy Gleason score, percentage of tumor involvement per biopsy specimen, transurethral prostate resection history, surgical experience and nerve-sparing technique were significantly associated with positive surgical margin rate. In multivariate analyses, preoperative prostate specific antigen level (OR: 1.03, p=0.06), percentage of tumor involvement per biopsy specimen (OR: 7,14, p<0,001), surgical experience (OR: 2.35, p=0.011) and unilateral nerve-sparing technique (OR: 1.81, p=0.018) were independent predictive factors for surgical margin positivity. Conclusion Preoperative prostate specific antigen level, percentage of tumor involvement per biopsy specimen, surgical experience and nerve-sparing technique are the most important predictive factors of surgical margin positivity in patients undergoing radical prostatectomy for localized prostate cancer.Item Prevalence of Daytime Urinary Incontinence and Related Risk Factors in Primary School Children in Turkey(KOREAN UROLOGICAL ASSOC, 2014-01-01) Bolat, Deniz; Acar, Ismail Cenk; Zumrutbas, Ali Ersin; Eskicorapci, Saadettin; Sancak, Eyup Burak; Zencir, Mehmet; Turan, Tahir; Sinik, ZaferPurpose: Urinary incontinence is one of the major urinary symptoms in children and adolescents and can lead to major distress for the affected children and their parents. In accordance with the definitions of the Standardization Committee of the International Children's Continence Society, daytime urinary incontinence (DUI) is uncontrollable leakage of urine during the day. The aim of this cross-sectional study was to investigate the prevalence and associated risk factors of DUI in Turkish primary school children. Materials and Methods: The questionnaire, which covered sociodemographic variables and the voiding habits of the children, was completed by the parents of 2,353 children who were attending primary school in Denizli, a developing city of Turkey. The children's voiding habits were evaluated by use of the Dysfunctional Voiding and Incontinence Symptoms Score, which is a validated questionnaire. Children with a history of neurological or urological diseases were excluded. Results: The participation rate was 91.9\% (2,164 people). The overall prevalence of DUI was 8.0\%. The incidence of DUI tended to decrease with increasing age and was not significantly different between genders (boys, 8.8\%
