    Introduction and Objective. Disadvantages associated with direct high b-value measurements may be avoided with use of computed diffusion-weighted imaging (cDWI). The purpose of this study is to assess the diagnostic performance of cDWI image sets calculated for high b-values of 1500, 2000, and 3000 s/mm(2). Materials and Methods. Twenty-eight patients who underwent multiparametric MRI of the prostate and radical prostatectomy consecutively were enrolled in this retrospective study. Using a software developed at our institute, cDWI 1500, cDWI 2000, and cDWI 3000 image sets were generated by fitting a monoexponential model. Index lesions on cDWI image sets were scored by two radiologists in consensus considering lesion conspicuity, suppression of background prostate tissue, distortion, image set preferability, and contrast ratio measurements were performed. Results. Lesion detection rates are the same for computed b-values of 2000 and 3000 s/ mm 2 and are better than b-values of 1500 s/ mm(2). Best lesion conspicuity and best background prostate tissue suppression are provided by cDWI(3000) image set. cDWI(2000) image set provides the best zonal anatomical delineation and less distortion and was chosen as the most preferred image set. Average contrast ratio measured on these image sets shows almost a linear relation with the b-values. Conclusion. cDWI 2000 image set with similar conspicuity and the same lesion detection rate, but better zonal anatomical delineation, and less distortion, was chosen as the preferable image set.

    The real-life management of overactive bladder: Turkish Continence Society multicenter prospective cohort study with short-term outcome
    (Wiley, 2019) Zümrütbaş, Ali E.; Çitgez, Sinharib; Acar, Ömer; İzol, Volkan; Uzun, Hakki; Kabay, Şahin; Demirkesen, Oktay; Yazıcı, Cenk
    Introduction Turkish Continence Society aimed to analyze how overactive bladder (OAB) is being managed in routine practice by the urologists in Turkey. Material and methods Fourteen urology departments were randomly selected to represent the whole population in this multicenter study. An online data entry and storage software was created for patient recruitment and data assessment. A survey including demographic data, daily habits, lower urinary tract symptoms, and Turkish-validated OAB-V8 and ICIQ-SF questionnaires were completed by all patients. Second part of the survey, including the questions about clinical evaluation and management of the patient, was completed by the treating physician. Results A total of 507 patients (394 female and 113 male) were included. Behavioral therapy was recommended to 73.2% of female and 81.4% of male patients although bladder diary was requested for 59.5% and 52.7% of the female and male patients, respectively. In the first visit, 86.1% of the female and 89.3% of the male patients were given antimuscarinics (P = .431). Antimuscarinic-related side effects occurred in 94.9% and 88.9% of the female and male patients, respectively (P = .937). However, the rate of medical treatment change due to antimuscarinic-related side effects was only 1.7% in female and 4.8% in male patients at the end of 4 months. Conclusions Behavioral therapy and antimuscarinics were the preferred initial treatment modalities of OAB in concordance with the guidelines. Despite guideline recommendations, bladder diaries were not utilized in half of the patients. Insufficient efficacy appeared to be the main reason for treatment modification.
