The effect of systemic inflammatory index and systemic inflammatory response index on success of varicoselectomy.

BACKGROUND: Varicocele is the most common correctable cause of male infertility. The treatment of varicocele is surgery. However, which patients will benefit from the surgery is controversial. Our aims to investigate the effect of systemic immune-inflammation index (SII) and systemic inflammatory response index (SIRI) on varicocelectomy success. METHODS: Patients who underwent varicocelectomy in our clinic between January 2016 and June 2022 were analyzed retrospectively. Varicocelectomy success was defined as >50% increase in post-operative total motile sperm count (TMSC) in those with pre- operative TMSC > 5 million and at least 100% increase in those with <5 million. The patients were divided into two groups as benefiting from the treatment (Group 1) and no benefits (Group 2). RESULTS: Of the 207 patients who underwent varicocelectomy, 144 (69.6%) of them improved their semen parameters, and 63 (30.4%) did not. The optimum cut-off value of SII was 334.6, with an AUC of 0.733 (95% CI: 0.665-0.813). The best cut-off value for SIRI of 0.882, with an AUC of 0.692 (95% CI: 0.607-0.772). The highest sensitivity and specificity were 0.692 and 0.601 (p < 0.001). In the multivariate analysis, only SII (OR: 3.152, 95% CI: 1.316-7.358; p = 0.003) and SIRI (OR: 2.919, 95% CI: 1.472-5.774; p = 0.002) were independent predictive factors for varicocelectomy success. CONCLUSIONS: Our results showed that preoperative SII and SIRI values were lower in infertile patients who underwent successful varicocelectomy. Therefore, we think that these parameters will be useful in identifying patients who will benefit before varicocelectomy.

Disease management in a patient diagnosed with COVID-19 disease during induction intravesical BCG therapy: A case report and review of the literature.

OBJECTIVE: To discuss the patient diagnosed with COVID-19 disease while receiving intravesical induction bacillus Calmette-Guérin (BCG) treatment for non-muscle-invasive bladder cancer, its management in the light of the literature. PATIENT AND METHODS: A 52-year-old male patient, who received intravesical BCG treatment for high-grade pT1 papillary urothelial carcinoma, presented 12 h after taking the fourth dose of induction therapy 38.2° fever and chills. The patient's reverse transcriptase-polymerase chain reaction test was positive, and Thorax CT imaging showed a few ground-glass pneumonic infiltrations in bilateral lung bases consistent with COVID-19 disease. RESULTS: Although international urology associations have current recommendations regarding the pandemic process, only one study has made specific recommendations regarding the patient group diagnosed with COVID-19 while receiving intravesical BCG treatment. According to this recommendation, we interrupted our patient's BCG treatment for 3 weeks and then completed the treatment for 6 weeks. A maintenance treatment not exceeding 1 year was planned. CONCLUSION: This group of patients' recommendation is to delay BCG therapy for at least 3 weeks after initial symptoms to allow for complete recovery. Although the administration schedule varies, maintenance therapy is recommended for no more than 1 year.

Extraprostatic extension in multiparametric MRI; Is presurgical detection possible?

INTRODUCTION: Extraprostatic extension (EPE) is one of the important factors affecting the prognosis of prostate cancer (PCa). Therefore, preoperative evaluation of the presence of EPE is essential in multiparametric magnetic resonance imaging (mpMRI) examination. However, for the evaluation of mpMRI, objective criteria are needed to detect EPE, especially microscopic EPE. AIM: To evaluate the efficacy of 1.5T MRI using lesion length (LL) and tumor-capsule contact length (TCL) in detecting EPE in PCa. METHODS: A total of 110 patients who underwent radical prostatectomy due to PCa were enrolled. Preoperative MR images were evaluated retrospectively by two independent observers who did not know the histopathological results. The observers evaluated LL and TCL. The radiological findings, including lesion location, were verified using histopathological mapping. RESULTS: Multiparametric MRI examination of the prostate demonstrated low sensitivity (Observer 1; 40.4% and Observer 2; 40.4%) but high specificity (Observer 1; 96.6% and Observer 2; 84.5%), with significant differences for detecting EPE (Observer 1, P < 0.0001; Observer 2, P = 0.003). The increased PI-RADS score correlated positively with the increased EPE rate (P < 0.0001 for both observers). The mean LL and TCL values were statistically significantly higher in patients with EPE than in patients without EPE. The TCL was a significant parameter for EPE, with high sensitivity and low for both observers. For both observes the cutoff value of LL for EPE was 14.5 mm, and the cutoff value of TCL for EPE was 9.5 mm. Histopathological LL value (28 ± 12,3 mm) was higher than radiological LLs (Observer 1; 22,14 ± 10,15 mm and Observer 2; 19,06 ± 8,61). CONCLUSION: The results revealed that 1.5T MRI demonstrated low sensitivity and high specificity in detecting EPE. The LL and TCL may be indirectly beneficial in detecting EPE. Considering the radiological underestimation of LL may be helpful before PCa surgery.

Comparative analysis of ureteroscopic laser lithotripsy and extracorporeal shock wave lithotripsy in the treatment of childhood proximal ureteral stones.

PURPOSE: This study aims to make a comparative analysis of the superiority of ESWL and URS in proximal ureteral stones in children. METHODS: A total of 155 patients under the age of 15 were included in the study. The patients were divided into two groups as Group 1 (n = 80, ESWL) and Group 2 (n = 75, URS) according to the type of procedure performed. The patients in both groups were evaluated in terms of age, gender, lateralization, stone size, stone volüme, stone density, and preoperative hydronephrosis. In addition, both methods used were compared in terms of success rate, time, cost, hospitalization and complications. RESULTS: The mean age were 7.4 ± 2.1 in Group-1 and 8.1 ± 1.8 in Group-2. Demographic, clinical and laboratory data of both groups were similar. The hospitalization time, procedure time, success rate and cost were significantly higher in Group-2. The complication rate was significantly higher in Group-2 (p < 0.001). There was a significant negative correlation between ESWL success and stone volume (ρ - 0.375, p = 0.001) and stone density (ρ - 0.283, p = 0.011). CONCLUSION: ESWL can be performed as the first line treatment of proximal ureteral stones in children due to its daily use, low cost, short procedure time and low complication rate. Increasing stone volume and density reduces the success of ESWL.

The role of the resistive index in predicting testicular atrophy after orchiopexy in unilateral undescended testis.

PURPOSE: One of the most important complications of undescended testis (UDT) surgery is testicular atrophy (TA). We aimed to investigate the factors associated with TA in children who underwent orchiopexy for unilateral UDT. METHODS: The data of 215 patients aged < 15 years who underwent orchiopexy for unilateral UDT between November 2019 and September 2022 were analyzed retrospectively. Clinical, radiological, surgical, and follow-up findings were recorded. RESULTS: TA was observed in 29 (13.5%) patients. Mean resistive index (RI) values were 0.44 ± 0.06, 0.54 ± 0.09 and 0.69 ± 0.1 in low, middle and high testicular locations, respectively, and intratesticular RI increased significantly as the testis location raised (p < 0.001). After orchiopexy, the mean testis volume ratio (TVR) increased significantly (0.63 ± 0.13 vs. 0.77 ± 0.15, p < 0.001). Besides, the mean RI values decreased significantly in the postoperative follow-up (0.53 ± 0.12 vs. 0.47 ± 0.13, p < 0.001). In multivariate regression analysis, testicular high location (OR 4.332, 95% CI 2.244-6.578, p = 0.002), deferens-epididymal anomaly (OR 3.134, 95% CI 1.345-7.146, p = 0.021), TVR ≤ 0.5 (OR 5.679, 95% CI 2.953-12.892, p < 0.001) and RI ≥ 0.6 (OR 7.158, 95% CI 3.936-14.569, p < 0.001) were independent predictive factors for TA after orchiopexy. CONCLUSION: Higher testis location, deferens-epididymis anomaly, preoperative TVR and RI were independent predictive factors for TA after orchiopexy in unilateral UDT. The results of the study will help surgeons to predict TA before orchiopexy.

Could Penile Mondor's Disease Worsen Symptoms in Patients with Erectile Dysfunction?

BACKGROUND: To determine the impact of Penile Mondor's disease (PMD) in patients with erectile dysfunction (ED). METHODS: Forty-seven patients diagnosed with PMD were included in the study and analyzed prospectively. The patients were divided into two groups according to the presence of ED at admission. The patients with ED were named Group 1, and those without ED were named Group 2. The International Index of Erectile Function (IIEF-5) and Beck Anxiety Inventory (BAI) forms at admission, 3rd, and 6th months were compared. RESULTS: There were 21 (44.6%) patients in Group 1 and 26 (55.4%) patients in Group 2. The mean patient ages in Group 1 and Group 2 were 38.1 ± 7.5 and 26.9 ± 10.3 years, respectively (p < 0.001). The mean admission IIEF-5 score was 19.52 ± 1.21 in Group 1 and 22.92 ± 1.23 in Group 2. After treatment, the mean IIEF-5 scores in Group 1 were 19.24 ± 1.14 and 19.09 ± 1.09 at the 3rd and 6th months, respectively. The mean IIEF-5 scores in Group 2 was 22.77 ± 0.99 and 22.96 ± 1.08 at 3rd and 6th months, respectively. In Group 1, the 6th-month IIEF-5 score was lower than the initial score (p = 0.026). In Group 1, the mean BAI score at 6 months increased compared to admission (6.0 ± 1.27 vs 5.43 ± 1.43, p = 0.015). CONCLUSION: PMD can worsen symptoms in men with ED who have a low IIEF5 score. The anxiety of recurrence of PMD during sexual intercourse may have caused this situation, or this may also be due to the natural progression of ED.

Effect of pelvic lymph node dissection and its extent on oncological outcomes in intermediate-risk prostate cancer patients: A multicenter study of the Turkish Uro-oncology Association.

BACKGROUND: Pelvic lymph node dissection (PLND) is the gold standard method for lymph node staging in prostate cancer. We aimed to evaluate the effect of PLND combined with radical prostatectomy (RP) on oncological outcomes in D'Amico intermediate-risk prostate cancer (IRPC) patients. METHODS: Patients with D'Amico IRPC were included in the study. In the overall cohort and subgroups (biopsy International Society of Urological Pathology [ISUP] grade group 2 and 3), patients were divided into two groups as PLND and no-PLND. More extensive PLND, defined as a number of removed nodes (NRN) ≥ 75th percentile. RESULTS: After exclusion, a total of 631 patients were included: 351 (55.6%) had PLND and 280 (44.4%) had no-PLND. The mean age was 63.1 ± 3.60 years. The median NRN was 8.0 (1.0-40.0). The mean follow-up period was 47.7 ± 37.5 months. The lymph node involvement (LNI) rate was 5.7% in the overall cohort, 3.9% in ISUP grade 2, and 10.8% in ISUP grade 3. Patients with PLND were associated with more aggressive clinicopathologic characteristics but no significant difference in biochemical recurrence-free survival (BCRFS) was found between patients with PLND and no-PLND (p = 0.642). In the subgroup analysis for ISUP grades 2 and 3, no significant difference in BCRFS outcomes was found in patients with PLND and No-PLND (p = 0.680 and p = 0.922). Also, PLND extent had no effect on BCRFS (p = 0.569). The multivariable Cox regression model adjusted for preoperative tumor characteristics revealed that prostate specific antigen (PSA) (HR: 1.18, 95% CI: 1.01-1.25; p = 0.048) was an independent predictor of biochemical recurrence (BCR). The optimum cut-off value for PSA, which can predict BCRFS, was assigned to be 7.81 ng/ml, with an AUC of 0.63 (95% CI: 0.571-0.688). The highest sensitivity and specificity were 0.667 and 0.549. CONCLUSION: Overall and cancer-specific survival analyzes were not evaluated because not enough events were observed. Neither PLND nor its extent improved BCRFS outcomes in IRPC. The LNI rate is low in patients with biopsy ISUP grade 2 and the BCR rate is low in those with PSA < 7.81 ng/dl so PLND can be omitted in these IRPC patients.

Is there an association between urine biochemical parameters on admission and the severity OF COVID-19?

AIM: To determine the importance of urinary biochemical parameters on the severity of coronavirus disease-2019 (COVID-19). METHODS: One hundred and thirty-three patients who were diagnosed with COVID-19 were retrospectively included. Groups were formed according to the severity of their disease (moderate [n = 85], severe [n = 29] and critical = [n = 19]), and an additional control group was created from healthy individuals (n = 50). We investigated the correlation between urine biochemical parameters and the severity of the disease. RESULTS: Erythrocyturia, proteinuria and glucosuria rates were significantly higher in patients than in the controls. In patients, the median urine specific gravity (SG) was lower (P < .001), and the median potential of hydrogen (pH) value was higher compared with the controls (P < .001). In correlation analyses, there were strong positive correlations between disease severity and age (r = 0.545, P < .001), RR (r = 0.838, P < .001) and proteinuria (r = 0.462, P < .001), while there was a strong negative correlation with SpO2 (r = -0.839, P = .001). On multivariate analysis, age (OR: 1.06, 95% CI 1.03-1.10, P = .035), respiratory rate ≥30 breaths/min (OR: 4.72, 95% CI 1.26-6.24, P < .0031), SpO2  ≤ 93% (OR: 3.82, 95% CI 1.18-5.82, P = .001) and proteinuria (OR: 1.13, 95%CI 1.02-2.1, P = .023) were independent predictive factors for disease severity. CONCLUSION: Proteinuria in routine urine analysis, which is one of the parameters that can be easily applied in the application, may be related to the severity of the COVID-19 disease.

What is the role of pre-operative blood parameters in forecasting varicocelectomy success?

BACKGROUND: We aimed to examine the effects of pre-operative blood values on varicocelectomy success. MATERIALS AND METHODS: A total of 130 patients who underwent varicocelectomy in our clinic were retrospectively analyzed. Operation success was defined as the return of all semen parameters (concentration, progressive motility, and morphology) to normal values 6 months after surgery. The patients were separated as two groups as benefiting from the treatment (Group A) and not (Group B). RESULTS: The best cut-off value for the neutrophil/lymphocyte ratio (NLR), which can predict varicocelectomy success, was assigned to be 2.27, with AUC of 0.859 (%95 CI 0.795-0.922). The highest sensitivity and specificity were 0.857 and 0.731 (p < 0.001). The best cut-off value for the mean platelet volüme (MPV) value, which can predict varicocelectomy success, was assigned to be 9.45, with AUC of 0.729 (%95 CI 0.639-0.819). The highest sensitivity and specificity were 0.655 and 0.635 (p < 0.001). Binary logistic regression analysis showed NLR ratio (odds ratio (OR): 11.2, p < 0.001) and MPV (OR: 2.65, p = 0.002) parameters as independent predictive factors in predicting varicocelectomy success. DISCUSSION AND CONCLUSION: Our study showed that low NLR ratio (≤2.27) and high MPV (≥9.45) ratio levels may be a useful pre-operative predictive tool in identifying men who benefit most from varicocelectomy in infertile patients with varicocoele.

The Effect of Percutaneous Nephrolithotomy on the Estimated Glomerular Filtration Rate in Patients with Chronic Kidney Disease.

Objective: We evaluated the influence of percutaneous nephrolithotomy (PCNL) on the estimated glomerular filtration rate (eGFR) in patients with chronic kidney disease (CKD). Materials and Methods: Between September 2007 and April 2019, 280 patients with a preoperative eGFR level <90 mL/min/1.73 m2 and who underwent PCNL were retrospectively examined. The primary endpoint of this study was the effect of PCNL on eGFR levels in the 1st and 12th month after surgery in patients with CKD according to CKD stages. The secondary endpoint of this study was the identification of potential risk factors for deteriorated eGFRs. Results: The mean eGFR of patients was 48.7 ± 17 mL/min/1.73 m2 in the preoperative period, 54.7 ± 21 mL/min/1.73 m2 in the postoperative 1st month, and 59.1 ± 23.2 mL/min/1.73 m2 in the postoperative 12th month. It was determined that the increases in eGFRs in the postoperative 1st and 12th months were significant in all CKD stages (p < 0.005). Compared with preoperative values, the eGFR value was reduced in 61 (21.8%) patients in the 1st month and 49 (17.5%) patients in the 12th month. When these patients were compared with those in the stable eGFR and recovery group, multiaccess PCNL was an independent risk factor for renal function deterioration at the postoperative 1st and 12th month on multivariate analysis (odds ratios were 6.94 and 9.46, respectively). Conclusion: PCNL was found to have a positive effect on short- and long-term eGFRs in patients with CKD. However, multiaccess PCNL may have adversely affected eGFRs in both the short and long term.

Possible role of the receptor of advanced glycation end products (RAGE) in the clinical course of prostate neoplasia in patients with and without type 2 diabetes mellitus.

AIM: The expression of the cognate receptor of advanced glycation end products (RAGE) in malignant tissues of patients with type 2 diabetes has been suggested as a co-factor determining the clinical course and prognosis. We aimed to investigate the relationship between RAGE expression and clinicopathological features of prostate neoplasia. METHODS: Tissue samples of 197 patients, 64 (24 patients with type 2 diabetes and 40 controls) with benign prostate hyperplasia (BPH) and 133 (71 patients with type 2 diabetes and 62 controls) with localised or metastatic prostate cancer (LPCa/MetPCa) were included in the study. The expression of RAGE in prostate specimens was studied immunohistochemically. RAGE scores were determined according to the extent of immunoreactivity and staining intensity. RESULTS: RAGE expression in BPH group (patients with type 2 diabetes and controls) was negative. Patients with both LPCa and MetPCa had significantly higher scores than those with BPH (P < .001). The mean RAGE scores of patients with type 2 diabetes LPCa and MetPCa were 4.71 ± 3.14 and 4.97 ± 3.69. The mean scores of control LPCa and MetPCa were 1.52 ± 1.87 and 1.69 ± 1.58, respectively. The scores of patients with type 2 diabetes LPCa and MetPCa were significantly higher than those of control LPCa and MetPCa (P = .01 and P < .001, respectively). CONCLUSION: We found higher RAGE expression levels in malignant prostate neoplasia than in BPH. As expected, patients with diabetes had higher scores than control patients. Disease progression and survival parameters were worse in patients with high RAGE levels. RAGE expression may be a useful biomarker for the diagnosis and prognosis of prostate cancer.

Predictive values of blood urea nitrogen/creatinine ratio and other routine blood parameters on disease severity and survival of COVID-19 patients.

We aimed to examine independent predictive factors for the severity and survival of COVID-19 disease, from routine blood parameters, especially the blood urea nitrogen (BUN)/creatinine (Cr) ratio. A total of 139 patients with COVID-19 were investigated at Siirt State Hospital. According to the disease severity, the patients were categorized as three groups (moderate: 85, severe: 54, and critical: 20). Then, patients were divided into two groups: nonsevere (moderate) and severe (severe and critical). Demographic, clinical data, and routine blood parameters were analyzed. In multivariate model adjusted for potential confounders BUN/Cr ratio (odds ratio [OR] = 1.70; 95% confidence interval [CI]: 1.20-2.40; P = .002) and neutrophil to lymphocyte ratio (NLR) (OR = 2.21; 95% CI: 1.20-4.30; P < .001) were independent predictive factors for disease severity. In multivariate Cox proportional hazard model BUN/Cr ratio (hazard ratio [HR] = 1.02; 95% CI: 1.01-1.05; P = .030), and NLR (HR = 1.17; 95% CI: 1.06-1.30; P = .020) were independent predictors for survival of COVID-19 disease. The optimal thresholds of the BUN/Cr ratio at 33.5 and 51.7 had the superior possibility for severe disease and mortality, area under the curve (AUC) were 0.98 and 0.95, respectively. The optimal thresholds of NLR at 3.27 and 5.72 had a superior possibility for severe disease and mortality, AUC were 0.87 and 0.85, respectively. BUN/Cr and NLR are independent predictors for COVID-19 patient severity and survival. Routine evaluation of BUN/Cr and NLR can help identify high-risk cases with COVID-19.

Flank Pain as a Symptom of COVID-19.

The COVID-19 disease is spreading rapidly worldwide, and no vaccine or very effective drug has been found yet. However, the transmission rate of the disease can be reduced by taking precautions. Therefore, it is essential to detect the patients early to prevent the spread of the disease.1,2 We report a case of 26-year-old male patient who was admitted to our urology outpatient clinic with the complaint of flank pain and had incidental findings of COVID-19 in the lung bases on abdominal CT.

Can preoperative gonadotropin and testosterone levels predict the success of varicocelectomy?

We examined the effects of preoperative hormonal values on varicocelectomy success. A total of 136 patients who underwent varicocelectomy for infertility in our clinic were analysed retrospectively. Improvement in semen quality was defined as >50% increase in post-operative total motile sperm count (TMSC) in those with preoperative TMSC >5 million and at least 100% increase in those with <5 million. The patients were divided into two groups as benefiting from the treatment (Group A) and no benefits (Group B). The best cut-off value for follicle-stimulating hormone (FSH) and the luteinising hormone/testosterone ratio (LTR) that can predict varicocelectomy success were 7.01 and 0.016 with an area under the curve of 0.844 and 0.856 respectively. The highest sensitivities and specificities of FSH and LTR were 0.845 and 0.788 and 0.821 and 0.846 respectively. Binary logistic regression analysis showed FSH (odds ratio [OR]: 3.7; p < .001) and LTR (OR: 5.2; p < .001) as independent predictive factors in predicting varicocelectomy success. Our study demonstrated that low FSH (7.01 IU/L) and LTR (<.016) can be a useful preoperative predictive tool to help identify men who benefit most from varicocelectomy in infertile patients with varicocele.

Protective effect of Alpha-Linolenic acid on Lipopolysaccharide-Induced Orchitis in mice.

Previous studies have demonstrated that polyunsaturated fatty acids (PUFAs) have anti-inflammatory effects. One specific PUFA, alpha-linolenic acid (ALA), shows both anti-inflammatory and antioxidant properties. In the testes, inflammatory mediators are known to increase when orchitis is induced by bacterial lipopolysaccharide (LPS). This study aimed to determine whether the anti-inflammatory properties of ALA could have a protective effect against LPS-induced orchitis in mice. The mice were divided into untreated control, orchitis and ALA-treated orchitis groups. Orchitis was induced by intraperitoneal injection of LPS. The ALA-treated group was administered ALA by gavage three days before intraperitoneal LPS injection. Cyclooxygenase-2 (COX-2), cytosolic phospholipase A2 (cPLA2), inducible nitric oxide synthase (iNOS) enzymes and nuclear factor kappa-B (NF-κB) in the testes, as well as serum interleukin 6 (IL-6) and tumour necrosis factor-alpha (TNF-α), were analysed using enzyme-linked immunosorbent assay (ELISA) tests. LPS administration increased the expression of several inflammatory mediators, including IL-6, TNF-α and NF-κB, as well as the COX-2, cPLA2 and iNOS enzymes. ALA administration significantly prevented the LPS-induced increases in these inflammatory mediators and enzymes (p < .05). The anti-inflammatory and antioxidant effects of ALA may make it a useful candidate for the treatment of orchitis caused by bacterial LPS.

Could flank pain be an indicator of COVID-19 infection?

Background: We describe the incidental detection of patients infiltrates due to COVID-19 in lung basal sections in patients undergoing abdominal computed tomography (CT) with flank pain attending the urology outpatient clinic during the current pandemic. Methods: We retrospectively analysed 276 patients admitted to the Siirt Training and Research Hospital Urology outpatients clinic between 15 March 2020 and 9 August 2020 with a complaint of flank pain and undergoing non-contrast abdominal CT. A total of 10 patients with COVID-19 compatible findings in CT were defined as the study group. A control group was formed from 10 patients with only urological pathologies (kidney stones, ureteral stones, and hydronephrosis) without a COVID-19 compatible appearance on CT. Results: Ten (3.6 %) patients were identified with COVID-19 and pneumonic infiltrations in the basal regions of the lungs; diagnosis was made by cross-sectional abdominal CT. The visual analog scale (VAS) score of flank pain was significantly higher in the control group (p<0.001); these subjects had urological pathology and no evidence of COVID-19 in the basal regions of the lungs on abdominal CT. There were no signs of COVID-19 disease detected during the admissions procedure in the urology outpatient clinic, including fever, cough, and shortness of breath. Conclusion: During the COVID-19 pandemic, it is important to consider a diagnosis of COVID_19 in patients reporting non-severe flank pain if no urological pathology is evident on abdominal CT scans.

Diagnostic efficacy of 18F-FDG PET/CT in patients with adrenal incidentaloma.

BACKGROUND: The management of adrenal incidentaloma is still a challenge with respect to determining its functionality (hormone secretion) and malignancy. In this light, we performed 18F-FDG PET/CT scan to assess the SUVmax values in different adrenal masses including Cushing syndrome, pheochromocytoma, primary hyperaldosteronism and non-functional adrenal adenomas. METHODS: Total 109 (73 F, 36 M) patients with adrenal mass (incidentaloma), mean age of 53.3 ± 10.2 years (range, 24-70) were screened by 18F-FDG PET/CT. Data of 18F-FDG PET/CT imaging of the patients were assessed by the same specialist. Adrenal masses were identified according to the calculated standardized uptake values (SUVs). Clinical examination, 24-h urine cortisol, catecholamine metabolites, 1-mg dexamethasone suppression test, aldosterone/renin ratio and serum electrolytes were analyzed. RESULTS: Based on the clinical and hormonal evaluations, there were 100 patients with non-functional adrenal mass, four with cortisol-secreting, four with pheochromocytomas and one with aldosterone-secreting adenoma. Mean adrenal mass diameter of 109 patients was 2.1 ± 4.3 (range, 1-6.5 cm). The 18F-FDG PET/CT imaging of the patients revealed that lower SUVmax values were found in non-functional adrenal masses (SUVmax 3.2) when compared to the functional adrenal masses including four with cortisol-secreting adenoma (SUVmax 10.1); four with pheochromcytoma (SUVmax 8.7) and one with aldosterone-secreting adenomas (SUVmax 3.30). Cortisol-secreting (Cushing syndrome) adrenal masses showed the highest SUVmax value (10.1), and a cut-off SUVmax of 4.135 was found with an 84.6% sensitivity and 75.6% specificity cortisol-secreting adrenal adenoma. CONCLUSIONS: Consistent with the similar studies, non-functional adrenal adenomas typically do not show increased FDG uptake and a certain form of functional adenoma could present various FDG uptake in FDG PET/CT. Especially functional adrenal adenomas (cortisol secreting was the highest) showed increased FDG uptake in comparison to the non-functional adrenal masses. Therefore, setting a specific SUVmax value in the differentiation of malignant adrenal lesion from the benign one is risky and further studies, including a high number of functional adrenal mass are needed.

Multidisciplinary approach for patients with functional and non-functional adrenal masses and review of the literature.

BACKGROUND: Adrenal incidentalomas are adrenal masses that are discovered by imaging tests performed for other reasons. AIMS: In this retrospective study, we analysed 229 Turkish patients with adrenal masses and who presented with or without complaints. STUDY DESIGN: Descriptive retrospective study and review of the literature. METHODS: This study conducted a retrospective review of 229 patients with adrenal incidentalomas that were referred to Cukurova University Hospital's endocrinological department between 2009 and 2014. We reviewed detailed patient histories, physical examination findings, and symptoms and signs related to hormonal hypersecretion or malignant neoplasm and recorded clinical indications for performing diagnostic radiological imaging. The statistical analysis of data was performed using SPSS-19 software. RESULTS: Of the 229 patients reviewed, 195 (85.2%) had non-functional, benign adrenal adenomas, and 34 (14.8%) had functional lesions. Among those with functional lesions, 8 (3.5%) had lesions that secreted excess cortisol, 11 (4.8%) had lesions that secreted aldosterone, and 15 (6.6%) had lesions that secreted catecholamines. Eighty-four patients included in the study (36.8%) underwent adrenalectomy; in 14 of these cases, the adrenalectomy was performed before surgical treatment criteria occurred. The most frequent pathologic diagnosis was adrenal cortical neoplasia (n = 38); 32 of these patients had adenomas (Weiss <4 criteria), and 6 had carcinomas (Weiss >4 criteria). Other patient diagnoses included benign pheochromocytoma (n = 13), pseudocyst (n = 12), metastasis (n = 10), haemorrhage (n = 3), necrosis (n = 1), hyperplasia (n = 2), and other (n = 5). CONCLUSIONS: Detailed endocrinological and radiological assessments of the mass nature and hormone status are necessary in cases of adrenal incidentaloma. Appropriate surgical treatment or periodic follow-up must be determined based on the assessment results.
