A comparative analysis of surgically excised hereditary and sporadic pheochromocytomas: Insights from a single-center experience.

Pheochromocytoma is a tumor that usually originating from adrenal medullary chromaffin cells and producing one or more catecholamines, can manifest as hereditary or sporadic. While the majority pheochromocytomas are sporadic, hereditary forms are often associated with genetic syndromes such as von Hippel-Lindau, multiple endocrine neoplasia type 2, and neurofibromatosis type 1. This study aims to analyze data from our series of surgically excited pheochromocytoma patients and compare the characteristics between hereditary and sporadic cases. We retrospectively evaluated 33 diagnosed pheochromocytoma patients, documenting clinical features, surgical complications, and tumor characteristics in both hereditary and sporadic cases. Among the patients, 21% (7 individuals) had hereditary pheochromocytoma, while 79% (26 individuals) had sporadic cases. During diagnosis, hereditary pheochromocytoma patients exhibited a significantly lower mean age compared to the sporadic group (26.4 ± 9.9 years vs. 50.4 ± 14.0 years; p < 0.001). The maximum tumor size was also lower in hereditary cases compared to sporadic cases (p = 0.004). Adrenal tumor localization analysis showed that 63.6% were right-sided, 24.2% were left-sided, and 12.1% were bilateral. Laboratory analysis revealed significantly higher urinary norepinephrine levels in hereditary pheochromocytoma patients (p = 0.021). Our findings suggest that hereditary pheochromocytoma cases are characterized by a younger age at diagnosis, smaller tumor size, and a higher prevalence of multiple bilateral adrenal adenomas. We recommend genetic testing for all pheochromocytoma patients, particularly those with early-onset disease and bilateral adrenal tumors.

Job satisfaction, depression severity and quality of life ratings of perioperative nurses in robotic-assisted and laparoscopic surgery.

The rapid introduction of technological developments into healthcare systems adds another layer of complexity to the already demanding jobs of nurses, particularly for those working in perioperative care. In the present study, our primary aim is job satisfaction, whereas the secondary outcomes are psychological well-being and quality of life (QoL) ratings of perioperative nurses who take part in robotic-assisted and pure laparoscopic surgery. A total of 101 perioperative nurses in six different centers were included in the study. Fifty-one of the nurses were working in robotic-assisted laparoscopic surgery and 50 of them were working in pure laparoscopic surgery. All participants responded to Minnesota Job Satisfaction Questionnaire (MJSQ), Beck Depression Inventory (BDI) and SF-36 QoL Measurement Survey. The two groups did not differ in their total MJSQ, BDI and SF-36 QoL scores (pMJSQ:0.066, pBDI:0.329, pSF-36-QoL:0.136). In addition, there were no differences between the two groups in their intrinsic job satisfaction and extrinsic job satisfaction sub-scores (pintrinsic: 0.473, pextrinsic:0.121). Overall, 18.9% of the nurses reported having moderate to extreme depressive symptoms and most of them (87.1%) had low to moderate levels of job satisfaction. Finally, QoL ratings was generally at moderate levels. Perioperative nurses who work in robotic-assisted laparoscopic surgery do not differ from those working in pure laparoscopic surgery in terms of their job satisfaction, psychological well-being, and QoL ratings. In addition, across groups' psychological well-being, job satisfaction, and QoL ratings were not particularly high, suggesting that more attention needs to be paid to improving the work conditions of perioperative nurses.

Evaluation of Sexual Function in Patients with Lower Lumbar Disc Herniation: A Comparison of Pre- and Postoperative Status.

BACKGROUND: Neuroregulation of sexual functions requires coordination of parasympathetic, sympathetic, and somatosensory neuronal pathways. The nerves formed by the lower lumbar plexus provide the innervation of the urogenital organs. Lower lumbar disc hernias (LDHs) might impair the neuroregulation of sexual functions by compressing the neural structures. This prospective study aims to evaluate the effect of lower LDHs on libido and sexual dysfunctions. METHODS: A total of 61 sexually active patients diagnosed with single-level LDH who underwent unilateral microdiscectomy were included in the study. The patients' healthy sex partners were included in study as controls. The International Sexual Function Index-5 (IIEF-5) and Female Sexual Function Index (FSFI) were used for sexual assessment of male and female participants, respectively. Visual Analog Scale (VAS) was used for pain assessment. RESULTS: According to the FSFI scores, all 20 female patients had preoperative sexual dysfunction, which improved in 15 (75%) patients after surgery (p < 0.001). According to the IIEF-5 score for men, 38 of 41 male patients had preoperative sexual dysfunction, which improved in 26 (68.4%) patients postoperatively (p < 0.001). CONCLUSION: The preoperative sexual dysfunctions of LDH patients improved significantly after the microdiscectomy.

Male Urethral Stricture in Patients with Metabolic Syndrome.

OBJECTIVE: Urethral stricture is characterized by fibrosis that decreases urine flow. Metabolic syndrome is a complex disorder that causes fibrosis in many organs. This study aimed to evaluate the relationship between metabolic syndrome and appearance of urethral stricture and effects of metabolic syndrome on the recurrence of urethral stricture in patients with primary urethral stricture who underwent direct visual internal urethrotomy. MATERIALS AND METHODS: One hundred thirty-two male patients who underwent direct visual internal urethrotomy between 2014 and 2021 because of primary urethral stricture were included. Location, length, and type of urethral stricture, time from diagnosis to surgery, postoperative follow-up, time from surgery to recurrence, and postoperative follow-up duration with a urethral catheter were retrospectively analyzed and association with metabolic syndrome was evaluated. RESULTS: The mean age was 50.48 ± 17.94 years. Recurrence was found in 34.1% and metabolic syndrome in 27.3%. Postoperative follow-up duration was significantly longer in patients with recurrence than in those without (P=.033). There was no statistically significant difference in terms of metabolic syndrome and postoperative urethral catheterization between patients with and without recurrence (P=.126, P=.714, respectively). Postoperative clean intermittent self-catheterization use was found to be statistically higher in patients with recurrence than in patients without recurrence (P=.018). Postoperative urinary tract infection rate was found to be significantly higher in patients with metabolic syndrome compared to patients without metabolic syndrome (P=.001). CONCLUSION: Metabolic syndrome was not associated with recurrence. However, postoperative urinary tract infections were more common in patients with metabolic syndrome than in patients without. Clean intermittent self-catheterization used postoperatively may increase the risk of stricture.

Selection for antimicrobial prophylaxis in emergency and elective transurethral procedures: Susceptibility pattern in Türkiye.

BACKGROUND: In this study, we aimed to determine the most appropriate antimicrobial agents for prophylactic antibiotic use during emergency and elective transurethral procedures. METHODS: The study was conducted in five hospitals located in five different geographical regions of Türkiye. The microorganism cultured in urine before emergency and elective transurethral procedures in these centers between March 2021 and March 2022 were reviewed retrospectively from the hospital records. Demographic data (age and gender) of the patients, comorbid disorders, previous urological procedures, anomalies of the urogenital tract, use of urethral catheters (permanent or clean intermittent catheterization), cultured microorganisms, and antibiotic susceptibilities were noted. The patients hospitalized or had antibiotics for any reason in the previous 1 month were excluded from the study. RESULTS: A total of 1450 patients, 742 men (51.2%) and 708 women (48.8%), were included in the study. The mean age of the patients was 55.3±19.36 (1-98) years. Diabetes mellitus was evident in 271 (18.7%) patients. The five most common microorgan-isms cultured in urine, in order of frequency, were: ESBL (-) Escherichia coli in 418 (28.8%), ESBL (+) E. coli in 309 (21.3%), Klebsiella pneumonia in 183 (12.6%), Enterococcus faecalis in 124 (8.6%), and Pseudomonas aeruginosa in 89 (6.1%). The susceptibility rates to antimicrobial agents recommended for prophylaxis by the American Urology Association and the European Association of Urology guidelines were found as follows: cefepime 87.1%, ampicillin+sulbactam 84%, TMP-SMX 71.6%, amoxicillin+clavulanate 63.5%, cefoxitin 59%, ceftazidime 58.6%, cefuroxime 43.5%, ceftriaxone 43%, and cefixime 38.4%. CONCLUSION: We found that currently recommended antimicrobials provide poor coverage for the most common pathogens isolated. Urologists should consider patient-based antibiotic prophylaxis in endoscopic urethral procedures, follow appropriate proto-cols, and consider local antibiotic resistance.

A Retrospective Analysis of 83 Patients with Testicular Mass Who Underwent Testis-Sparing Surgery: The Eurasian Uro-oncology Association Multicenter Study.

INTRODUCTION: Herein, we analyzed the histopathological, oncological and functional outcomes of testis-sparing surgery (TSS) in patients with distinct risk for testicular cancer. METHODS: This is a multicenter retrospective study on consecutive patients who underwent TSS. Patients were categorized in high- or low-risk testicular germ cell tumor (TGCT) according to the presence/absence of features compatible with testicular dysgenesis syndrome. Histology was categorized per size and risk groups. RESULTS: TSS was performed in 83 patients (86 tumors) of them, 27 in the high-risk group. Fifty-nine patients had a non-tumoral contralateral testis present. Sixty masses and 26 masses were benign and TGCTs, respectively. No statistical differences were observed in mean age (30.9 ± 10.32 years), pathological tumor size (14.67 ± 6.7 mm) between risk groups or between benign and malignant tumors (p = 0.608). When categorized per risk groups, 22 (73.3%) and 4 (7.1%) of the TSS specimens were malignant in the high- and low-risk patient groups, respectively. Univariate analysis showed that the only independent variable significantly related to malignant outcome was previous history of TGCT. During a mean follow-up of 25.5 ± 22.7 months, no patient developed systemic disease. Local recurrence was detected in 5 patients and received radical orchiectomy. Postoperative testosterone levels remained normal in 88% of those patients with normal preoperative level. No erectile dysfunction was reported in patients with benign lesions. CONCLUSION: TSS is a safe and feasible approach with adequate cancer control, and preservation of sexual function is possible in 2/3 of patients harboring malignancy. Incidence of TGCT varies extremely between patients at high and low risk for TGCT requiring a careful consideration and counseling.

Effect of the Ureteral Access Sheath Size on Acute Kidney Injury Biomarkers in Retrograde Intrarenal Surgery: A Prospective, Randomized Study.

INTRODUCTION: The aim of the study was to investigate the effect of the diameter of the ureteral access sheath (UAS) used during RIRS on kidney injury based on acute kidney injury (AKI) biomarkers. METHODS: This prospectively randomized controlled study included a total of 125 patients divided into three groups: group 1 (n = 52) in which a 12/14 Fr UAS was used, group 2 (n = 52) in which a 9.5/11.5 Fr UAS was used, and group 3 (n = 21) that was designed as the control group with no urogenital disease history. Urine samples were collected preoperatively and at the postoperative second and 24th hours after surgery and analyzed for AKI using the urinary kidney injury molecule-1 (uKIM-1), N-acetyl-ß-D-glucosaminidase, and neutrophil gelatinase-associated lipocain biomarkers. RESULTS: In group 1, there was no statistical change in any of the three AKI biomarkers at the postoperative second or 24th hour compared to the preoperative period. In group 2, the values of all three AKI biomarkers were statistically significantly increased at the postoperative second and 24th hours compared to the preoperative period while no statistical difference was observed between the two postoperative evaluation times. At the postoperative second hour, the uKIM-1 value was statistically significantly higher in group 2 compared to group 1 (p = 0.043). CONCLUSIONS: The results of our study showed that AKI was not observed in RIRS performed with a 12/14 Fr UAS while the use of a 9.5/11.5 Fr UAS resulted in AKI according to the assessment of the related biomarkers.

Impact of Urinary pH on the Efficacy of a Postoperative Single Instillation of Mitomycin-C.

OBJECTIVE: To assess the effect of the urinary pH value on the efficacy of a postoperative single instillation of mitomycin-C. STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: Department of Urology, Ankara Numune Training and Research Hospital, Ankara, Turkey from 2011 to 2016. METHODOLOGY: Patients newly diagnosed with low-risk non-muscle invasive bladder cancer and given a postoperative single instillation of mitomycin-C were retrospectively reviewed. The demographic data and pre-instillation urinary pH values of the patients were recorded. All patients included in the study (n=117) were followed up for five years. The primary outcome was the time to the first recurrence. The patients were divided into two groups: Group 1 consisted of 87 patients with no recurrence and Group 2 comprised 30 patients that had recurrence during the follow-up. RESULTS: The mean pre-instillation urinary pH value was significantly lower in Group 2 than in Group 1 (5.89 vs. 5.37, p <0.001). The receiver operating characteristic analysis revealed that the cut-off value of urinary pH in predicting recurrence was 5.25. The patients with a urinary pH value of 5.25 or greater had significantly higher recurrence-free survival rates. CONCLUSIONS: The patients with higher urinary pH before a single instillation of mitomycin-C had better recurrence-free survival. KEY WORDS: Bladder cancer, Mitomycin-C, Single instillation, Urinary pH.

Comparison of holmium laser enucleation with bipolar transurethral enucleation of the prostate in patients with benign prostatic hyperplasia: Results of a multicentre study.

To assess the efficacy and morbidity of the holmium laser enucleation of the prostate and bipolar transurethral enucleation of the prostate in patients with benign prostatic hyperplasia. The study included 60 (55%) and 49 (45%) patients who underwent laser and bipolar enucleation of the prostate respectively. According to the perioperative data, except for length of hospital stay and enucleated prostate weight, all the remaining parameters were similar between the groups. There were significant differences between the preoperative and the postoperative third and 12th month voiding parameters in both groups. In the laser group, the maximum urine flow rate value was better than the bipolar group at the postoperative third and 12th months. However, we did not find any statistically significant difference between the groups in terms of the serum prostate-specific antigen level, International Prostate Symptom Score and postvoid residual urine volume at the postoperative third and 12th months. Our results show that both laser and bipolar techniques are effective minimally invasive surgical treatment options for men with benign prostatic hyperplasia. When compared to bipolar technique, laser technique provides shorter hospital stay, more prostatic tissue enucleation and better maximum urine flow rate values.

The Impact of Ureteral Access Sheath Size on Perioperative Parameters and Postoperative Ureteral Stricture in Retrograde Intrarenal Surgery.

Objective: To investigate the effect of the diameter of ureteral access sheath (UAS) used during retrograde intrarenal surgery (RIRS) on operative parameters, perioperative ureteral injury, and ureteral stricture development. Materials and Methods: The study was designed as a prospective randomized controlled trial and included 320 patients who underwent RIRS. The patients were divided into two groups according to the diameter of UAS (9.5F/11.5F [Group 1] and 12F/14F [Group 2]) placed during the operation. At the end of the operation, ureteral injury was checked visually using semirigid ureterorenoscopy and classified according to the ureter injury scale. In the postoperative first year, the control CT urography images were used to observe newly developing ureteral dilatation. Results: There was no statistical difference between the two groups in terms of patient and stone characteristics, operative time, postoperative stone-free rate, and postoperative infection development parameters. In Group 1, 30 (18.8%) of the patients had low-grade and 8 (5%) of the patients had high-grade ureteral injury, while in Group 2, 44 (27.5%) had low-grade and 19 (11.9%) had high-grade ureteral injury (p = 0.013). In the postoperative period, ureteral stricture was found in 5 (1.6%) patients, of whom 4 (2.5%) were in Group 2 and 1 (0.6%) (p = 0.371). Conclusion: The results of our study showed that the use of a 12F/14F UAS in patients who are not previously stented increases the risk of high-grade ureteral injuries; however, despite this increase there is no difference in ureteral stricture formation.

What is the role of inflammatory markers in predicting spontaneous ureteral stone passage?

PURPOSE: To investigate the role of inflammatory markers in predicting the spontaneous passage of ureteral stones. METHODS: We retrospectively reviewed 279 patients with ureteral stones sized 4-10 mm that were managed conservatively. The patients were divided into two groups: Group 1 consisted of 137 patients who passed the stone spontaneously; Group 2 comprised 142 patients without spontaneous stone passage. The groups were compared using the Mann-Whitney U and chi-square tests. In addition, univariate and multivariate analyses were performed to identify the significance of the parameters. RESULTS: The mean age of the patients was 41.2 years. The patients in Group 1 had a significantly lower mean stone size, white blood cell count and neutrophil count. In addition, stone location, presence of hydronephrosis and history of urolithiasis were significantly different between the groups. Neutrophil percentage, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were insignificantly lower in Group 1. In a multivariate analysis, stone size, distal location and hydronephrosis status significantly predicted the spontaneous stone passage. However, inflammatory markers including white blood cell count, neutrophil count and neutrophil-to-lymphocyte ratio could not determine the likelihood of spontaneous stone passage. CONCLUSION: Our results suggest that inflammatory markers are no meaningful parameters for the prediction of spontaneous stone passage.

Can the Stone Scoring Systems Be Used to Predict Infective Complications of Retrograde Intrarenal Surgery?

OBJECTIVE: We aimed to evaluate whether the retrograde intrarenal surgery (RIRS) scoring systems (Resorlu-Unsal Stone Score [RUSS], modified Seoul National University Renal Stone Complexity Score [modified S-ReCS], and R.I.R.S. score) can predict the infective complications after RIRS. SUBJECT AND METHODS: A total of 581 patients who underwent RIRS for kidney stones were included in the study. All patients were evaluated for demographic data, medical history, radiological imaging methods before surgery, duration of surgery, and hospitalization time after surgery. Stone laterality, stone burden, stone size, stone density, the number of stones, stone localization, the presence of congenital kidney anomaly, and solitary kidney were evaluated preoperatively by computed tomography. The RUSS and modified S-ReCS and R.I.R.S. score of all patients were determined. RESULTS: Infective complications were detected in 47 (8.1%) patients who underwent RIRS. Fever developed in 27 subjects (4.6%), urinary infection in 15 (2.5%), sepsis in 2 (0.3%), and septic shock in 3 (0.5%) patients. In multivariate logistic regression analysis, age (OR = 1.8; 95% CI = 1-3.4; p = 0.049), surgical duration of >60 min (OR = 1.9; 95% CI = 1.1-3.5; p = 0.027), and high R.I.R.S score (OR = 8.9; 95% CI = 1.9-42.4; p = 0.006) were shown to be independent risk factors for the infective complications after RIRS. A receiver operating characteristic curve analysis showed that the R.I.R.S. score can be used as a marker to predict infective complications (AUC = 0.619, CI = 0.55-0.69; p = 0.007). CONCLUSION: We suggest that the R.I.R.S. score can be used to predict infective complications in RIRS.

Evaluation of factors associated with the detection of incidental prostate cancer after open prostatectomy for benign prostatic hyperplasia.

We aimed to evaluate the incidental prostate cancer (PCa) rate and predictive factors in patients who underwent open prostatectomy (OP) with a pre-diagnosis of benign prostatic hyperplasia (BPH). This study included patients with a pre-diagnosis of BPH, who underwent OP due to symptomatic prostate enlargement. Our database included age, medications, prostate-specific antigen (PSA), free/total PSA ratio, PSA density, digital rectal examination (DRE), prostate volume, serum neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, aspartate aminotransferase/alanine aminotransferase ratio, presence of metabolic syndrome (MetS) and histopathological results after OP. Of the 430 patients that underwent OP, 406 (94.4%) with a benign pathological diagnosis were evaluated as the benign group and 24 (5.6%) detected to have PCa constituted the incidental PCa group. The rate of incidental PCa was much higher in the elderly patients. The cut-off value of age was 71.5 years in the PCa group according to the receiver operating characteristic curve analysis. According to the multivariate analysis, DRE and the presence of MetS were effective in predicting PCa (p < .001 and p = .031, respectively). DRE was found 16 times more effective and MetS was 2.8 times more effective than the other parameters. Our results showed that DRE and the presence of MetS could be useful predictive factors of incidental PCa in OP.

Comparison of the impact of open and laparoscopic inguinal hernia operations on male sexual function and pain during sexual activity.

In the current study, we aimed to compare sexual function and pain during the sexual activity of men who underwent surgery with the open or laparoscopic total extraperitoneal hernia repair techniques. Patients were randomised into two groups according to the technique used during the operation: the Lichtenstein hernia repair open technique (n = 63) and the laparoscopic total extraperitoneal repair technique (n = 57). In both groups, postoperative sexual function score was significantly improved compared with the preoperative period (p < .001 for both), but the change was higher in the laparoscopy group (6.8 ± 3.7) compared with the open group (4.3 ± 4.4) (p < .001). In both groups, postoperative pain during sexual activity score was significantly decreased compared with the preoperative period (p = .001 for the open group and p < .001 for the laparoscopy group), with the amount of decrease being higher in the laparoscopy group (1.8 ± 0.9) compared with the other (1.1 ± 1.4) (p = .002). This study showed that both hernia repair techniques had a positive impact on sexual function and pain during sexual activity. The improvement in sexual parameters and pain during sexual intercourse was better in the laparoscopy group.

What Is the Interaction between Urine C-Reactive Protein, Prostatic Inflammation, and Doxazosin Treatment in Patients with Benign Prostatic Hyperplasia? A Pilot Study.

INTRODUCTION: It was aimed to show the relationship between benign prostatic hyperplasia and inflammation by measuring urinary C-reactive protein values before and after alpha-blocker treatment. METHODS: A total of 71 patients with a total prostate-specific antigen <3.5 ng/mL, International Prostate Symptom Score >7, and maximum urinary flow rate <15 mL/s were included in the study. Doxazosin 4 mg p.o. once daily was started orally as an alpha-blocker treatment. Serum and urine C-reactive protein values, International Prostate Symptom Score, maximum urinary flow rate, and the post-void residual volume of patients were recorded at the first admission and in the first month of alpha-blocker treatment. RESULTS: The mean age of the patients was 59.2 ± 7.5 years. The mean serum C-reactive protein values of the patients at the first admission and follow-up were 2.62 ± 1.8 (range, 0-5) mg/L and 2.83 ± 1.6 (0-6) mg/L, respectively. The mean urine C-reactive protein values of the patients at the first admission and follow-up were 0.45 ± 0.11 (range, 0.28-0.99) mg/L and 0.14 ± 0.04 (range, 0.79-0.328) mg/L, respectively, which was statistically significantly different. In the subgroup analysis, the urine C-reactive protein level change was more prominent in severely symptomatic patients than in moderately symptomatic patients. CONCLUSION: Our results showed that C-reactive protein was detectable in urine, alpha-blocker treatment significantly reduced urine C-reactive protein levels, and the decrease was more prominent in severely symptomatic patients.

The Impact of Surgical Approaches for Isolated Acetabulum Fracture on Sexual Functions: A Prospective Study.

OBJECTIVES: To investigate the effects of surgical modalities for isolated acetabular fractures on the sexual functions of patients and their partners. DESIGN: Prospective. SETTING: Level I trauma centre. PATIENTS/PARTICIPANTS: Sixty-five patients who had undergone open reduction and internal fixation because of isolated acetabular fractures who were sexually active before, together with their partners. INTERVENTION: Patients operated on for isolated acetabular fractures were divided into 3 groups according to surgical approaches: the Kocher-Langenbeck approach (n = 36), ilioinguinal approach (n = 16), and modified Stoppa approach (n = 13). MAIN OUTCOME MEASUREMENTS: Sexual functions of patients and their partners were evaluated with the 5-item version of the International Index of Erectile Function score and Female Sexual Function Index score preoperatively and at the postoperative first year after the rehabilitation period. RESULTS: The mean age of the patients was 41.8 ± 13.0 (18-69) years. In male patients, the mean 5-item version of the International Index of Erectile Function score had changed from 24.3 to 20.0 at the postoperative first year and the decrease in sexual function scores was less with the Kocher-Langenbeck approach. In female patients, the Female Sexual Function Index scores had decreased statistically significantly from 24.9 to 18.3 at the postoperative first year, but there was no statistically significant difference between surgical groups. Both male and female patients' partners' sexual function scores were also decreased at the postoperative first year. CONCLUSIONS: As a result of our study, it was observed that the posterior approach is more advantageous than anterior approaches in preserving the sexual functions of male patients in acetabular fracture surgery. However, the surgical approach did not affect the sexual functions of female patients. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

The impact of 18F-fluorodeoxyglucose PET/computed tomography on clinical staging in bladder cancer.

AIM: To determine the impact of 18F-FDG PET/computed tomography (CT) on clinical staging in bladder cancer with comparison to conventional CT and MRI. METHODS: A total of 142 patients who underwent 18F-FDG PET/CT imaging with a diagnosis of bladder cancer between 1 June 2019 and 31 December 2020 were screened retrospectively. Seventy patients who underwent diagnostic CT or MRI within 2 months before or after PET/CT were included in the study. The N and M stages determined by CT, MRI and PET/CT according to the eighth version of the TNM staging system were recorded. T-test was used to determine the levels of significant difference, and univariate logistic regression analysis was used to evaluate the impact of the T stage on nodal up-staging. RESULTS: According to the PET/CT, the N stage increased in 19 patients (27.14%) and decreased in seven patients (10%). Likewise, the M stage increased in 16 patients (22.86%) and decreased in seven patients (10%). The N stage determined by PET/CT was confirmed by pathologic examination in all cases in which the two modalities were inconsistent. In muscle-invasive cases, the rate of increase in the N stage after PET/CT (36.95%) was found to be significantly higher than in that of cases without invasion (8.33%) (P = 0.011). Increasing T stage was associated with an increase in the N stage after PET/CT (odds ratio: 2.33, 95% confidence interval: 1.02-5.28, P = 0.042). CONCLUSION: 18F-FDG PET/CT can potentially change the clinical stage determined by CT and MRI when used for staging in bladder cancer, and can lead to nodal up-staging particularly in cases with muscle-invasive bladder cancer.

Impact of the COVID-19 Pandemic on the Psychosexual Functions of Healthcare Workers.

BACKGROUND: A novel infection, COVID-19, emerged in China and soon became a global pandemic. Pandemic conditions have resulted in stress in the workplace and led to anxiety among healthcare workers (HCWs), having negative impacts on different aspects of their lives, including their sexual function. AIM: To evaluate the changes in the anxiety status of HCWs during the COVID-19 pandemic and the impact of anxiety on their sexual functions. METHODS: This is a longitudinal study based on an online survey conducted from April 2020 to February 2021 in hospitals designated as pandemic healthcare centers. An online survey link was sent to HCWs that provided consent for participation in the study. The anxiety status of the participants was assessed using the State Anxiety Inventory, and sexual function was evaluated using the International Index of Erectile Function-15 for men and Female Sexual Function Index for women. OUTCOMES: Scores obtained at the beginning of the pandemic were compared with those obtained at 6 months into the pandemic to determine the changes in the anxiety levels and sexual functions of the HCWs. RESULTS: A total of 399 HCWs participated in the survey, and the median age was 32 (20-60) years. Compared to the beginning of the pandemic, there was a significant increase in the State Anxiety Inventory score of the female and male HCWs at the sixth month of the pandemic. Among the women, the mean total Female Sexual Function Index score was 23.55 ± 8.69 at the beginning of the pandemic and 21.42 ± 8.91 at the sixth month, and there was a significant decrease in all parameters except pain. Among the men, the International Index of Erectile Function-15 total score was 62.75 ± 12.51 at the beginning of the pandemic and 55.1 ± 12.87 at the sixth month, indicating a significant decrease in all parameters. CLINICAL IMPLICATIONS: Considering that the pandemic will continue for a long time, more psychological support should be provided, and interventions should be made to protect the mental health of HCWs. STRENGTHS & LIMITATIONS: The strength of the study is that it had a fairly high number of participants across several institutions. However, being conducted in one country and the sample not being randomly selected and being based on voluntariness can be considered as limitations. CONCLUSION: Our results show that the COVID-19 pandemic has led to an increase in the anxiety levels of both female and male HCWs, and this situation has negatively affected their sexual functions.

Comparison of percutaneous nephrolithotomy and retrograde intrarenal surgery outcomes for kidney stones larger than 2 cm from Guy's stone scoring system perspective.

OBJECTIVE: To compare surgical outcomes of percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgeries (RIRS) as a result of kidney stones larger than 2 cm, together with Guy's stone scores (GSS). MATERIALS AND METHODS: The data of 811 patients with stone sizes 2-6 cm were operated using PNL (n = 361) and RIRS (n = 450) reviewed retrospectively. GSS were graded 1, 2, 3 or 4 according to the computed tomography findings. Stone-free rate (SFR), operation times, length of hospital stay (LOHS) and Clavien complications (CC) were recorded. RESULTS: Although mean operative times were significantly longer in the RIRS group than the PNL group in GSS grades 1, 2 and 3 (P < .001), it was similar between the two groups in GSS grade 4 (P = .186). SFRs in the PNL and RIRS group were 90.3% and 58.4% on post-operative 10th day (P < .001), and it raised up to 95.3% and 81.6% after secondary interventions (P < .001). Significantly higher SFRs observed in the PNL group in GSS grades 1, 2 and 3 categories. On postoperative 10th day, the SFRs were similar in both GSS grade 4 categories (P = .06). LOHS was longer in the PNL group (P < .001). Although LOHS was significantly longer only in GSS grade 3 (P = .043) and GSS grade 4 (P < .001) in the PNL group, it was similar in GSS grade 1 and 2 between groups. Clavien complications increased in line with GSS in the PNL group (P < .001), but the difference did not differ between GSS grade 3 and 4. CONCLUSION: SF of PNL in a single session and short operation time seems to be significant especially in GSS grades 1, 2 and 3 category stones. Although the number of patients in the GSS 4 group is very small to claim this, RIRS might be considered as an alternative to PNL in a special group of patients such as GSS grade 4 because of its lower complication rates and shorter LOHS.

The Role of Pentraxin-3, Fetuin-A and Sirtuin-7 in the Diagnosis of Prostate Cancer.

PURPOSE: Prostate canceris the most commonly diagnosed type of cancer and one of the leading causes of cancer-related death in men.Numerous efforts have been made to improve existing diagnostic methods and develop a new biomarker to identify patients with prostate cancer. In line with current literature, we preferred new serum-based biochemical markers as Pentraxin-3, Fetuin-A and Sirtuin-7 in the present study. MATERIALS AND METHODS: A total of 174 patients aged 42-76 years were included in the study. Patients with prostate cancer (n=38) were enrolled as Group 1 and patients with benign prostatic hyperplasia (n=136) as Group 2. The serum levels of Pentraxin-3, Fetuin-A and Sirtuin-7 levels were compared between the groups. RESULTS: The mean age of the patients was 61.9±7.6 years (p= .001). The mean serum Prostate Specific Antigen levels 32.0±59.6 (2.6-336) ng/mL and 10.0±11.3 (2.5-77.4) ng/mL in Group 1 and 2, respectively (p= .029). The mean serum levels of Pentraxin-3 and Fetuin-Ain Group 1 were statistically significantlydifferent from Group 2(3.3±4.4 ng/mL vs 1.8±2.4 ng/mL, p= .002 and 466.8±11.0 µg/mL vs 513.3±11.0 µg/mL,p= .041,respectively). There was no significant difference between Group 1 and 2 according to serum levels of Sirtuin-7 (12.7±8.2 ng/mL vs 12.7±12.4 ng/mL respectively, p= .145). CONCLUSION: Pentraxin-3, Fetuin-A and Sirtuin-7 may be effective in the diagnosis of prostate cancerin light of the current literature.In this study, it was found that Pentraxin-3 and Fetuin-A were significantly different in the diagnosis of prostate cancer.Larger-scale prospective studies are needed to determine the importance of Pentraxin-3 and Fetuin-A in the diagnosis of prostate cancer.
