Introduction: The most common form of priapism is ischaemic and its prevalence in men has increased in recent years as a result of intracavernosal drug use. Currently, there is no approved specific treatment for ischaemic priapism other than cavernosal aspiration, which can only provide detumescence. This study aims to evaluate the efficacy of intracavernosal mesenchymal stem cell (MSC) therapy in an ischaemic priapism model., Material and Methods: Thirty male Wistar albino rats were divided into three groups: sham (n = 6), priapism (n = 12) and priapism + MSC treatment (n = 12). The experimental groups were also divided into 1 and 12 h subgroups of ischaemic priapism. The experimental model was created using a vacuum erection device and constrictive tape technique, and intracavernosal MSC were applied immediately after the tape was removed. After 4 weeks, intracavernosal pressures (ICPs) and systemic mean arterial pressure (MAP) were measured. Penectomy was then performed to assess histopathological and molecular changes in the rats' penile tissues., Results: In the ischaemic priapism model, MSC therapy showed significant improvements in peak and mean ICPs and mean ICP/MAP ratio. Histopathological analysis showed significant increases in smooth-muscle/collagen ratio and e-NOS and n-NOS expression. Although there was a decrease in fibrosis, it was not significant. At the molecular level, there were significant decreases in TGF-beta and VEGF mRNA expression, whilst NGF and BDNF mRNA-expression levels showed significant increases with MSC therapy. In terms of ICPs, the therapy showed more significant improvements in short-term priapism. However, when looking at histopathological and molecular parameters, the therapy had positive effects on a wider range of parameters in the long-term priapism., Conclusion: MSC treatment improved cavernosal physiology and had positive effects at the histopathological and molecular level in the ischaemic priapism model., Competing Interests: Declarations.

Introduction: To evaluate the validity and reliability of the Turkish version of the Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index-10 (LURN SI-10)., Materials and Methods: In this, single-centre study, patients between 18 and 65 years old, who were suffering from lower urinary tract symptoms (LUTS) without any known urinary tract disease and on no medication, were enrolled. The control group consisted of participants, who were admitted to our clinic suffering from any complaint except LUTS and met all of the other inclusion and exclusion criteria. Participants' demographics such as age, sex, and level of education were recorded. The Turkish version of the LURN SI-10, International Prostate Symptom Score (IPSS) and Overactive Bladder Questionnaire (OAB-V8) were administered to all participants. Construct validity was evaluated by confirmatory factor analysis and concurrent validity was evaluated with correlations to similar measures. Internal consistency (Cronbach's alpha) was used to establish the scale's internal consistency reliability., Results: A total of 164 participants were included in the final analysis. Of those, 57% were male. The individuals were identified as being in the "patient group" (n = 86) and a "control group" (n = 78). The mean age was 48.24 ± 14.30 years. The median total LURN SI-10 scores of patient group and control group were 12.0 (9-18.25) and 4.0 (2.75-6), respectively. The LURN SI-10 questionnaire showed a high correlation with the IPSS and the OAB-V8 questionnaires (r: 0.761; p: 0.001; r: 0.737; p: 0.001, respectively) in concurrent validity analysis. Cronbach's alpha coefficient of the LURN SI-10 was 0.850., Conclusions: This promising measurement tool can be used to evaluate LUTS in Turkish women and men. Further studies should be conducted to assess the clinical usefulness of this questionnaire.

Purpose: to investigate the factors affecting post-treatment paternity intention in patients followed up after the diagnosis of testicular cancer and to make recommendations for the early postoperative period based on the identified factors., Materials and Methods: This prospective descriptive study included total 185 patients who presented to our outpatient clinic between February 2000 and July 2020 who had radical orchiectomy due to suspected testicular cancer based on physical examination and other assessments. Contact information was found for 88 of 185 patients, and accordingly, the patients were reached by one-to-one phone calls. Upon literature review, a questionnaire consisting of 10 previously validated items was developed by the researchers. The patients were compared by separating them into two groups composed of patients with (Group 1) and without (Group 2) paternity intention., Results: A total of 84 patients participated in the study, and the participation rate was 95.5%. It was found that 19 of 32 (38%) patients with paternity intention already had children. Only 21 (40%) of 52 patients without paternity intention were married. The mean age was 26.65 (18-39) years in Group 1, while it was 28.73 (19-45) years in Group 2. Tumor volume and serum tumor markers were higher in Group 2 than in Group 1. Parameters such as testicular side in which the tumor was located, smoking status, undescended testis history, and postsurgical chemotherapy history were not statistically significant difference between the two groups., Conclusion: The major findings included that the young aged, unmarried, and serious testicular cancer (Tumor volume and serum tumor markers were higher) can be affecting factors for testicular cancer patients' paternity intention. Early psychological counseling about paternity may be useful for testicular cancer patients.
