Studies have shown that healthcare professionals struggling with epidemics develop symptoms of post‐traumatic stress disorder. The aim of this study is to show how often and severely erectile dysfunction, one of the components of post‐traumatic stress disorder, is seen among healthcare professionals during COVID‐19 outbreak. The Impact of Event Scale‐Revised (IES‐R) and the Index of Erectile Function‐5 (IIEF‐5) were applied to 159 male healthcare professionals working in COVID‐19 units and a control group of 200 people. Healthcare professional group was divided into subgroups according to occupation (physician, nurse), age‐group (18–25, 26–30, >30), marital status and unit of work (Suspected Patient Area, Diagnosed Patient Area). Both stress disorder and erectile dysfunction were seen at higher rates in healthcare professionals group (p < .001). The median IIEF‐5 scores of nurses, married subjects and those working in the Diagnosed Patient Area, were found to be higher (p < .001, p = .014, p = .011 respectively). During the COVID‐19 outbreak, healthcare professionals are exposed to psychological trauma and their sexual function may be negatively affected. The measures to be taken are important to estimate which groups are more affected.

Background and Objectives: Percutaneous nephrolithotomy (PCNL) is a current treatment method with high success rates and low complication rates in treating large kidney stones. It can be conducted in different positions, especially supine and prone positions. PCNL in the supine position is becoming increasingly common due to its advantages, such as simultaneous retrograde intervention and better anesthesia management. This study aimed to assess how the choice of position impacts the PCNL learning curve. Materials and Methods: The results of the first 50 consecutive PCNL cases performed by two separate chief residents as primary surgeons in supine and prone positions in a reference center for stone treatment between August 2021 and January 2023 were evaluated. The two groups’ demographic and clinical data, stone-free rates, operation times, and fluoroscopy times were compared. Results: While the mean operation time was 94.6 ± 9.8 min in the supine PCNL group, it was 129.9 ± 20.3 min in the prone PCNL group (p < 0.001). Median fluoroscopy times in the supine PCNL and prone PCNL groups were 31 (10–89) seconds and 48 (23–156) seconds, respectively (p = 0.001). During the operation, the plateau was reached after the 10th case in the supine PCNL group, while it was reached after the 40th case in the prone PCNL group. Conclusions: For surgeons who are novices in performing PCNL, supine PCNL may offer both better results and a faster learning curve. Prospective and randomized studies can provide more robust conclusions on this subject.

The number of core biopsies required per region of interest (ROI) is controversial, as is the localization of the core to be taken from a lesion. This study aimed to determine the ideal biopsy core number and location in a multiparametric magnetic resonance imaging guided targeted prostate biopsy (TPB), without reducing the clinically significant prostate cancer (csPC) detection rate. Data of patients who had PI-RADS ≥3 lesions on multiparametric magnetic resonance imaging and underwent a TPB in our clinic between October 2020 and January 2022 were reviewed, retrospectively. The first and second cores were taken from the central part of the ROI, whereas the third and fourth cores were taken from the right and left peripheries of the ROI. We compared the csPC detection success of single-, 2-, 3-, and 4-core samplings. Software-based transrectal TPB was performed on 251 ROIs in a total of 167 patients. Internal Society of Urological Pathology Grade Group ≥2 cancer was detected in at least one core in 64 (25.4%) lesions. Moreover, csPC was detected in 42 (65.6%) ROIs in first-core biopsies; in 59 (92.2%) ROIs in first- and second-core biopsies; in 62 (96.9%) ROIs in first-, second-, and third-core biopsies; and in 64 (100%) ROIs in first-, second-, third-, and fourth-core biopsies. Using McNemar's test for comparison, a significant difference was found in terms of csPC detection success between performing first-core and second-core biopsies (65.6 – 92.2%, p < 0.001); by contrast, no significant difference was observed in csPC detection success between 2-core and 3-core biopsies (92.2% - 96.9%, p = 0.24). Furthermore, no significant difference existed between performing second-core and fourth-core biopsies in terms of csPC detection success (92.2%–100%, p = 0.07). We concluded that taking 2-core biopsies from the center of each ROIs during a transrectal TPB is sufficient for diagnosing csPC.

Objective: This study aimed to evaluate the impact of obesity on the outcomes of supine percutaneous nephrolithotomy (PCNL) in a tertiary care center. Understanding surgical outcomes in obese patients, given their rising prevalence and urolithiasis risk, is crucial for optimizing treatment strategies. Materials and Methods: This retrospective study included data from 256 patients aged 18 and older who underwent PCNL in the Galdakao-Valdivia position between July 2021 and July 2024 at a tertiary care hospital. Patients were categorized into three groups based on their body mass index (BMI): normal weight (BMI: 18-24.9 kg/m²), overweight (BMI: 25-29.9 kg/m²), and obese (BMI: 30-34.9 kg/m²). Demographic data, stone characteristics, operative time, fluoroscopy time, hospital stay, nephrostomy duration, stone-free rates (SFR), and complications were analyzed and compared across the three groups. Results: There was no significant difference between the groups regarding age, sex, stone laterality, location, or size (p>0.05). Median BMI values were significantly different between the groups (p0.05). No significant differences were found in operative time, fluoroscopy time, hospital stay, or nephrostomy time among the groups (p>0.05). Minor and major complication rates were similar across all groups (p>0.05). Conclusion: Obesity does not appear to significantly impact the outcomes of supine PCNL, including operative time, stone-free rates, or complication rates. These findings suggest that with experienced surgeons, supine PCNL is a safe and effective treatment option for obese patients, though further prospective studies are needed to confirm these results.

Objective: Combined biopsy (CBx) is a combination of multiparametric magnetic resonance imaging (MpMRI)-targeted prostate biopsy (FBx) and systematic biopsy (SBx). CBx offers highly accurate diagnostic rates, but the increased number of cores taken and the longer procedure time may pose challenges in tolerability compared to traditional biopsies in terms of pain and anxiety. This situation leads to the need to evaluate pain and anxiety. Methods: In a tertiary hospital in Turkey, 149 patients with suspicious lesions (PI-RADS ≥ 3 on MpMRI) who underwent transrectal CBx were included between May 2023 and August 2023. Following FBx, patients underwent a 12-core systematic biopsy. During CBx, 78 patients listened to classical music, while 71 patients used noise-canceling headphones without music. Ten minutes after the procedure, patients completed the Visual Analog Scale (VAS) and the State-Trait Anxiety Inventory (s-STAI, t-STAI) questionnaires to measure pain and anxiety. s-STAI determines how anxious a person feels at a specific moment. t-STAI indicates the general level of anxiety a person experiences independently of their current situation. Results: Median VAS score was 3.6 (3.0 – 4.3) in the music group and 5.4 (4.4 – 6.9) in the control group (p < 0.001). The median s-STAI score was 38 (34 – 44) in the music group and 44 (39 – 48) in the control group (p < 0.001). For t-STAI scores, no significant difference between groups was observed. Conclusion: Incorporating music during CBx, alongside traditional pain management, effectively reduces pain and anxiety levels. Its cost-effectiveness, accessibility, and non-invasive nature make routine use of music during CBx procedures advantageous for pain palliation.

Background and Objectives: In the surgical treatment of benign prostatic hyperplasia (BPH), laser enucleation of the prostate is recommended as an alternative to transurethral resection (TURP) and open prostatectomy (OP). The thulium fiber laser, with its superficial penetration depth, can offer a rapid learning process by causing less heat injury and capsule damage. This study compares the first 60 cases of an endourologist performing thulium fiber enucleation of the prostate (ThuFLEP) without a mentor to the results of OP and TURP performed by experienced surgeons. It also identifies the case number at which the operation time for ThuFLEP starts to plateau. Materials and Methods: Between 1 November 2021 and 1 November 2023, the initial 60 ThuFLEP cases of an endourologist with no prior enucleation experience were compared with TURP and OP operations performed by experienced surgeons. Since the first 60 ThuFLEP cases involved 80–120 cc prostates, TURP and OP operations within this size range performed during the same period were included in the study. The groups were assessed for age, preoperative and postoperative prostate volume, PSA levels, the IPSS, the IPSS Quality of Life (QoL), and maximum urinary flow (Qmax). The 60 consecutive ThuFLEP cases were divided into three groups of 20 (Groups 1, 2, and 3) and compared for operation time, IPSS, and Qmax. Results: The operation time for TURP was shorter than for ThuFLEP and OP (p < 0.001). There was no significant difference between ThuFLEP and OP in postoperative Qmax and IPSS, while TURP had lower values than the other two methods. For ThuFLEP, the operation time was longer in the first 20 cases but plateaued in groups 2 and 3 (p < 0.001). Postoperative Qmax and IPSS values showed no significant differences among the three ThuFLEP groups (p > 0.05). Conclusions: For large prostates, ThuFLEP provides better postoperative results than TURP and offers shorter catheterization and hospital stay times than OP. Its short learning curve makes it a preferable method for treating BPH compared to other laser techniques.
