A., YÜCEL S., Sircan-Kucuksayan A., ÇAM H. K., Savaş M., Yıldırım A., Ağras K., Baykara M., CANPOLAT M.© 2023 Elsevier Inc.Objective: To develop a near-infrared (NIR) spectroscopy device to diagnose testicular torsion with high sensitivity and specificity. Specifically, we aim to investigate the differentiation between testicular torsion from other pathologies such as orchidoepididymitis, varicocele, and hydrocele. Methods: Two LEDs with wavelengths of 660 nm and 940 nm were used as light sources in the device. Each wavelength was sent to the testicle successively, and a photodiode detected back-reflected diffuse light. The ratio of the light intensities of 660 nm and 940 nm was used as a diagnostic parameter. A multi-center clinical trial was performed in 5 different hospitals. Results: In total, 62 patients in urology clinics with acute testicular pain have been recruited for the study. The developed NIR spectroscopy correctly defined all 8 testicular torsion cases. Besides, 3 orchidoepididymitis, 1 varicocele, and 3 hydrocele cases were correctly distinguished from testicular torsion. Only 1 hydrocele case was misdiagnosed as torsion. The range of the ratio was between 0.14 and 1.16 overall measurements. The ratio varied between 0.14 and 0.3 for the testicle with torsion. The ratio was between 0.49 and 1.16 for the normal testicle and testicle with other pathologies mentioned above. Conclusion: We have chosen the threshold ratio of 0.4 to differentiate between the normal and torsion testis and diagnosed all the torsion cases among all normal and other pathologies. The developed optical device to diagnose testicular torsion is inexpensive, user-friendly, and works based on objective criteria with high sensitivity and specificity in real time.Publication Open Access Atypical Cell'' Parameter in Automated Urine Analysis for the Diagnosis of Bladder Cancer: A Retrospective Pilot Study(GALENOS YAYINCILIK, 2020-04-01) FİLİNTE, DENİZ; Tinay, Ilker; Sahin, Bahadir; Saracoglu, Sertac; Yanilmaz, Ozgur; Aksu, Mehmet Burak; Ayas, Ramazan; Filinte, Deniz; Cam, Haydar Kamil; Ilki, ArzuObjective: To evaluate the application of an automated urine analyzer (AUA) for the diagnosis of bladder cancer (BC) Materials and Methods: A retrospective data analysis of 2365 urine specimens from the department of urology has been performed and matched with those patients, who have undergone cystoscopic evaluation or surgical treatment for different urological pathologies during 2018. After matching, clinical records of the patients has been further evaluated in order to select patients with recent or previous BC diagnosis. To assess the diagnostic efficacy of AUA, patients were divided into five groups according to the patient history of BC and healthy controls. Results: A total of 106 patients are included in this study and the majority (69.8%) of the patients are follow-up patients with previous diagnosis and treatment of non-muscle invasive BC (NMIBC). For patients with low-risk NMIBC (n=27), the sensitivity and specificity were calculated as 75% and 100%. For patients with high-risk NMIBC (n=47), who were previously treated with intravesical BCG, the sensitivity and specificity were calculated as 54.5% and 83.3%. All patients in radical cystectomy group (n=7) with muscle invasive BC had positive urine analyses results for atypical cells. And none of the patients in the control group (n=8) had positive AUA results and cystoscopic evaluation also did not show any bladder mass suspicious for BC. Conclusion: The results of this retrospective pilot study showed acceptable sensitivity and specificity rates of the fluorescence flow cytometry based AUA and the results of the low-risk group are especially valuable regarding its potential use to decide on performing a follow-up cystoscopy or not. A prospective study is currently on progress to validate the findings of the current study.Publication Open Access Risk factors of patients with prostate cancer upgrading for international society of urological pathology grade group I after radical prostatectomy(2022-01-01) ÖZGÜR, GÜNAL; FİLİNTE, DENİZ; ÇAM, HAYDAR KAMİL; ÖZGÜR A., ÖZGÜR G., ŞAHİN B., FİLİNTE D., TİNAY İ., ÇAM H. K., TÜRKERİ N. L.Objective: This study aimed to determine the predictive factors for patients whose International Society of Urological Pathology (ISUP) score was upgraded in radical prostatectomy (RP) pathologies with a prostate biopsy pathology of ISUP grade group 1. Materials and Methods: Among patients who underwent RP in our clinic within 10 years, 158 patients with prostate biopsy pathology of ISUP grade group 1 were examined retrospectively. Age, serum prostate-specific antigen (PSA) level, prostate biopsy ISUP grade group, number of cores taken in the prostate biopsy, number of tumor-positive cores, RP pathology ISUP grade group, and pathological stage were evaluated. Results: The mean age (± standard) of the 158 patients whose prostate biopsy pathology was ISUP grade group 1 were 64.07 (±6.6). ISUP group upgrading was detected in 47 patients (29.7%). The mean PSA value of these patients was 10.6 ng/mL (±6.9). The mean PSA value of the other 111 patients without ISUP group upgrading was 7.98 ng/mL (±4.9). The serum PSA level was significantly higher in patients with upgraded ISUP in the RP pathology (p=0.02). The percentage of tumor-positive cores in the group with ISUP group upgrading (37%) was significantly higher than that in the group without ISUP group upgrading (27%) (p=0.01). The detection rates of surgical margin positivity (42.6% vs. 18%), capsule invasion (55.3% vs. 19.8%), and seminal vesicle invasion (23.6% vs. 3.6%) were also significantly higher in the upgraded ISUP group after RP (p<0.05). Conclusion: The results of this trial suggest that active surveillance may not be an appropriate option for patients with biopsy ISUP grade group 1 with PSA level >10 ng/mL. Moreover, the presence of a higher number and percentage of tumor-positive cores constituted risks of ISUP group upgrading with concomitant poor pathological outcomes such as surgical margin positivity, capsule invasion, and seminal vesicle invasion.Publication Open Access Does experience affect the cancer detection rate in cognitive fusion prostate biopsy? A comparison of the first and last 60 cases(2022-01-01) ÇAM, HAYDAR KAMİL; AKYÜZ O., ÇAM H. K.Objective: We aimed to determine the contribution of the clinical experience gained in cognitive fusion prostate biopsy with the increase in the number of cases to the cancer detection rate. Materials and Methods: The records of 120 patients who underwent cognitive fusion biopsy were retrospectively analyzed. All patients underwent 3-T multiparametric magnetic resonance imaging (Mp-MRI) and they were evaluated with Prostate Imaging Reporting and Data System (PIRADS). The initial 60 cases were included in group 1, and the later subsequent 60 cases performed by the same surgeon were included in group 2. Any cancer and clinically significant prostate cancer (CSPrCa) detection rates in groups 1 and 2 were compared. Results: The mean ages of the patients for group 1 and group 2 were determined as 64.08 ± 8.15 and 65.15 ± 6.93 years, respectively. Age, prostate specific antigen (PSA), prostate volumes and the number of suspicious lesions of the groups were similar. Any cancer positivity rate was 33.3% for group 1, and 40% for group 2, without any significant intergroup difference (p=0.494). CSPrCa positivity was 40% and 70.83% for groups 1 and 2, respectively, and there was a significant improvement in CSPrCa detection in favor of group 2 (p=0.027). Conclusion: Regarding the cognitive fusion biopsies, a learning curve is required. It was concluded that the rate of detecting clinically significant prostate cancer was almost doubled with the increased experience in fusion biopsy.Publication Metadata only Ürodi̇nami̇ işlemi̇nde standart şeki̇lli̇ bi̇r form ile hasta bi̇lgi̇lendi̇ri̇lmesi̇ni̇n kaygı düzeyleri̇ne etki̇si̇: Prospekti̇f kli̇ni̇k çalışma(2022-11-13) ŞAHİN, BAHADIR; ŞEKERCİ, ÇAĞRI AKIN; ONUR, AHMET RAHMİ; ÇAM, HAYDAR KAMİL; TARCAN, TUFAN; ÖZKAN O.

Materials and Methods: An online survey was used to identify the daily practices of urologists for men over the age of 45 with LUTS. Based on the EAU guidelines, an 11-item questionnaire was created. A link to the SurveyMonkey questionnaire was sent to members of a national urology association along with an e-mail message. Moreover, the data were analysed after collecting all of the responses. Results: Out of 1.182 urologists who received an invitation message, 166 (14.04%) responded and completed the questionnaire. The mean age of the urologists who responded was 4224+10.11. More than half of the participants (56.6% work at centres that have a urology residency programme. Furthermore, the most commonly performed laboratory test in men with LUTS was urinalysis. Approximately 90 0 /0 of urologists performed urinalysis. In addition, 84% of participants routinely measured prostate-specific antigen in every man between the ages of 45 and 75. In all men with LUTS, approximately half of the urologists routinely used renal function tests, urinary ultrasonography, post-void residual urine measurement, uroflowmetry, and symptom score assessment. For men with nocturia and/or storage phase symptoms, the majority of participants (69.9%) used a bladder diary. Moreover, urologists who worked at university hospitals were found to use bladder diaries significantly more frequently in their clinical practice (p=0.037). Conclusion: We discovered that there was no clinical approach standard among urologists for men with LUTS.Publication Metadata only The association of free testosterone levels with coronavirus disease 2019(2022) ILGIN, CAN; Apaydin, Tugce; Sahin, Bahadır; Dashdamirova, Saida; Dincer Yazan, Ceyda; Elbasan, Onur; Ilgin, Can; Bilgin, Hüseyin; Cam, Haydar Kamil; Bahramzada, Gunel; Kucuk, Aleyna; Haklar, Goncagul; Iliksu Gozu, Hulya
