Aims: To assess the outcomes of robotic surgery for patients with neurogenic lower urinary tract dysfunctions (NLUTD).

Materials And Methods: Studies evaluating the outcomes (efficacy and safety) of robot-assisted ileal conduit creation or artificial urinary sphincter (R-AUS) implantation or augmentation cystoplasty or continent urinary diversion creation in patients with NLUTD were included. The search strategy and studies selection were performed on Medline, Embase and Cochrane using the PICOS method according to the PRISMA statement (PROSPERO 2022 CRD42022333157).

Background: Lower urinary tract symptoms (LUTS) contribute to erectile dysfunction (ED) and premature ejaculation (PE). However, only a few studies have been conducted with representative groups of men that had well-balanced demographic characteristics. Thus, we aimed to confirm the effect of LUTS on ED and PE and to analyze the association between LUTS and men's sexual activity in a large representative cohort.

Article Synopsis
  • - Internal urethrotomy (IU) is commonly used for treating urethral strictures but has a high recurrence rate, with no current markers to predict this recurrence.
  • - A study of 250 male patients showed a 31.2% recurrence rate after IU, finding a significant correlation between monocyte to HDL-C ratio (MHR) and recurrence; higher MHR linked to increased recurrence risk.
  • - The research suggests that MHR could serve as a useful prognostic factor for predicting urethral stricture recurrence following IU, with an optimal cut-off value identified at 1.72.

Purpose: The effect of overactive bladder (OAB) on sexual health has been evaluated extensively for women but much less for men. Therefore, the aim of this study was to evaluate the relationship between OAB and men's sexual activity and the effect of OAB on erectile dysfunction (ED) and premature ejaculation (PE) in a large representative cohort of men at the population level.

Methods: This study was based on computer-assisted web interviews that used validated questionnaires.

Article Synopsis
  • Robot-assisted technology is becoming increasingly common in urological oncological surgery and is being applied to functional reconstructive and neuro-urology procedures, showing established benefits.
  • A literature review was conducted from PubMed to evaluate robotic applications in procedures like ureteric reimplantation and artificial urinary sphincters, highlighting the need for more prospective studies due to a current scarcity of data.
  • Despite the clear advantages of robotic assistance—such as improved ergonomics, reduced blood loss, and shorter hospital stays—further research with larger cohorts is necessary to confirm long-term efficacy and impact on patient outcomes.

Purpose: This study was conducted to determine the effect of listening to the sound of running water during urodynamics on the patient's anxiety and parameters in the pressure-flow study.

Methods: The population of the study, which was planned in the nonrandomized experimental study design, consisted of patients who will undergo urodynamics in the Urology Department of a city hospital in Istanbul between September 2022 and January 2023, and the sample consisted of 60 patients, 30 of which were in the experimental group and 30 in the control group. During the pressure-flow study, the patients in the experimental group listened to the sound of running water from a smartphone, while the patients in the control group did not undergo any intervention during urodynamics.

Purpose: Female representation at scientific conferences is crucial for encouraging women pursuing an academic career. Nevertheless, gender inequity at urological conferences is common place and women are often stereotyped choosing functional urology. However, there is no evidence whether female representation is higher in functional urology.

Objective: The aim of this study was to evaluate the quality of life of patients with lifelong and acquired premature ejaculation and to examine its relationship with depression and anxiety.

Methods: Between February 2017 and January 2018, a total of 175 patients with premature ejaculation and 132 control men who applied to the urology department of the training and research hospital with the complaint of Premature Ejaculation were included. Patients were divided into three groups according to International Society for Sexual Medicine (ISSM) criteria as follows: Group 1, lifelong premature ejaculation; Group 2, acquired premature ejaculation, and Group 3, control group without premature ejaculation.

Mean platelet volume (MPV) has been related to erectile dysfunction (ED). However, its value in predicting therapeutic response to phosphodiesterase-5 inhibitors is not evaluated. This study aimed to investigate the value of MPV as a marker for the prediction of the response of the tadalafil treatment of ED.

The aim of this study was to evaluate the effect of vitamin D replacement in patients with lower urinary tract symptoms (LUTS)/erectile dysfunction (ED) who did not respond to tadalafil 5 mg treatment. Patients who applied to the Andrology Clinic with LUTS/ED between September 2017 and August 2020 and used 5 mg Tadalafil daily for treatment and did not benefit from treatment for 1 month were included in the study. Vitamin D levels of the patients were analysed and Vitamin D3 100,000 IU/week oral therapy was administered for a month to the patients with low levels of Vitamin D(<20 ng/ml).

Erectile dysfunction (ED) is seen very often in the men with type 2 diabetes mellitus (DM). Due to the ability of vitamin D to reduce endothelial damage and oxidative stress, its role in preventing cardiovascular risk has been demonstrated in some studies. Since ED and cardiovascular disease have common pathogenic mechanisms, many studies have evaluated a possible relationship between vitamin D deficiency and ED.
