RESUMEN
Background and objective Bladder cancer (BC) is a common urothelial neoplasm, with non-muscle invasive forms comprising about 75% of cases and generally having better outcomes than muscle-invasive types. Accurate preoperative grading and staging of BC are essential for appropriate treatment planning. This study investigates the efficacy of computerized tomography (CT) in correlating the morphological features of tumors to predict the histopathological grades of BC. Materials and methods This retrospective cohort involved 100 patients diagnosed with non-muscle invasive BC, who underwent transurethral resection of bladder tumor (TUR-BT) between January 2010 and August 2021. CT imaging, utilizing a 128-slice CT scanner, was employed to measure the tumor height (H) and contact length (CL). The study considered morphometric parameters across axial, coronal, and sagittal planes. Statistical analyses were conducted, comparing radiological findings with histopathological evaluations. Tumor grading was determined according to the 2004/2016 WHO classification. Results Among the 100 patients with primary bladder tumors, 15 were female and 85 were male, with a mean age of 65.28 ± 7.11 years. Furthermore, 58 had high-grade bladder tumors, while 42 had low-grade bladder tumors. Across all planes, high-grade tumors exhibited higher values for the tumor H, CL, and the tumor height-to-contact length (H/CL) ratio compared to low-grade tumors (p<0.05). Notably, the specificity, sensitivity, and diagnostic accuracy of the tumor CL were higher than those of the tumor H and the tumor H/CL ratio. A tumor CL exceeding 19.1mm measured in the axial plane demonstrated 83% sensitivity and specificity for high-grade tumors. Conclusion The measured CL of the tumor in the axial plane on computerized tomography urography has high sensitivity and specificity in detecting high-grade tumors.
RESUMEN
PURPOSE: Prostate-specific membrane antigen (PSMA)-targeted PET/CT is a well-established imaging method in prostate cancer (PC) for both staging and restaging, and also for theranostic applications. An alternative imaging method is crucial for 15% PSMA-negative cases. We aimed to investigate the contribution of 68 Ga-DOTA-FAPI-04 PET/CT to PC imaging. PATIENTS AND METHODS: Thirty-six patients diagnosed with PC were included. Patients underwent both 68 Ga-PSMA PET/CT and 68 Ga-DOTA-FAPI-04 PET/CT imaging within 1 week. In staging group, primary tumor uptake values were compared, and also correlations were done with histopathological findings, MRI findings, and total PSA levels. In biochemical recurrence group, the uptake values in prostatic region and metastases were evaluated to define the local recurrence or metastatic disease. RESULTS: In staging group, PSMA PET showed increased uptake in the primary lesion area in 14/27 (52%) patients, whereas 20/27 (74%) patients were positive in FAPI-04 PET. FAPI-04 positivity was found to be quite high, such as 54%, in PSMA-negative patients. A significant difference was observed between ISUP grade 1-3 patients and ISUP grade 4-5 patients in FAPI-04 PET ( P = 0.03). Local recurrence was detected in 3 patients, pelvic lymph node metastasis in 1 patient, and sacrum metastasis in 1 patient in biochemical recurrence group, and all of the lesions had more intense uptake in PSMA PET than FAPI-04 PET. CONCLUSIONS: FAPI PET imaging seems to have a potential to contribute PSMA PET imaging with FAPI positivity in more than half of PSMA-negative cases. Also, FAPI-targeted radionuclide therapy may be a promising method in patients resistant to PSMA-targeted therapy.

AIM: To compare serum endothelial-specific molecule-1 (ESM-1 or endocan) levels between individuals with primary bladder cancer (BC) who have various pathological features of BC and healthy volunteers. MATERIALS AND METHODS: 154 consecutive patients with primary BC (Group-1) and 52 healthy volunteers (Group-2) were accepted into this prospective, non-randomized, observational research between January 2017 and December 2018. Peripheral blood samples were obtained from each participant to measure serum ESM-1/endocan levels. Group-1 was further divided into subgroups as Group-1A (pTa), Group-1B (pT1) and Group-1C (pT2) based on the transurethral resection of bladder tumour (TURBT) histopathological results. In addition Group-1 was divided into other subgroups based on pathological features of BC including tumor grade, tumor volume and muscle-invasive status. Groups were compared statistically regarding ESM-1/endocan levels. RESULTS: Median age of the individuals was 63 (22) years in Group-1 and 66 (11) years in Group-2 (p = 0.051). There were 140 (90.9%) males and 14 (9.1%) females in Group-1 and 30 (57.7%) males and 22 (42.3%) females in Group-2 (p < 0.001). The serum ESM-1/endocan measurements were lower in Group-2 than in Group-1 (p = 0.018). Of the patients in Group-1, 62 (40.3%) had low-grade tumors and 92 (59.7%) had high-grade tumors. When Group-1 was further divided into other subgroups according to different pathological features of BC such as tumor stage, grade, muscle-invasive status and tumor volume it was detected that there was a statistically meaningful difference between all subgroups of Group-1 and Group-2 in terms of serum ESM-1/endocan levels (p < 0.05 for each). The serum ESM-1/endocan cut-off value (3.472 ng/mL) had a specificity of 57.7%, sensitivity of 59.1%, NPV (negative predictive value) of 32.3% and PPV (positive predictive value) of 80.5% for predicting the presence of BC with an AUC (Area Under the Curve) of 0.609 (95% confidence interval (CI) 0.524-0.694; p = 0.018). CONCLUSIONS: The serum ESM-1/endocan levels can be considered a potentially useful predictor for BC. Higher serum ESM-1/endocan levels are related with poor pathological outcomes in BC.

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. A detailed medical history of patients was obtained and physical examinations were performed. Intravaginal ejaculation latency time (IELT) was recorded and patients were administered International Erectile Function Index-5 (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT), Sexual Health Inventory for Men (SHIM), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI)-1 and STAI-2, and Short Form-36 (SF-36). RESULTS: The mean mental component score (MCS) of the SF-36 was 51.65±6.57 in the lifelong premature ejaculation group, 49.33±8.65 in the acquired premature ejaculation group, and 61.12±11.09 in the control group (p<0.0001). The mean physical component score (PCS) was 50.99±7.43 in the lifelong premature ejaculation group, 48.32±11.58 in the acquired premature ejaculation group, and 55.17±8.10 in the control group (p<0.0001). Quality of life of premature ejaculation patients as assessed by SF-36 was lower in the subscales of physical functioning, general health perception, vitality, and role limitations due to emotional functioning, compared to the control group. CONCLUSIONS: Lifelong and acquired premature ejaculation patients deteriorate their quality of life: the deterioration in these patients' quality of life also negatively affects their depression and anxiety states.

OBJECTIVE: The aim of this study was to evaluate the adjuvant treatment preferences and effects on disease progression in patients with pathologically positive lymph node prostate cancer. METHODS: Patients who underwent radical prostatectomy from the prostate cancer database of the Turkish Urooncology Association with lymph node involvement were included in the study. Database includes prostate cancer patients from many experience Urooncology centers of Turkey. Adjuvant treatment approaches and the factors that effect the PSA recurrrence was analysed. RESULTS: Postoperative median 2 (1-3) lymph nodes were found to be positive, and the median lymph node density was reported as 0.13 (0.07-0.25). Seventy-four percent of patients received adjuvant treatment postoperatively. Seventy four of the patients (46.54%) received hormonal therapy in combination with radiotherapy; 47 of them (29.55%) received only hormonal treatment and 20(12.57%) only received radiotherapy. The number of lymph nodes removed was less in the group requiring adjuvant treatment, and this group had a higher rate of surgical margin positivity and seminal vesicle invasion. In addition, adjuvant treatment group had a statistically significant higher lymph node density. There was no significant difference in Kaplan-Meier method comparing 5-year PSA recurrence-free survival in patients with and without adjuvant therapy. When the patient clustered as non-adjuvant, only hormonal therapy and hormonal therapy with radiotherapy, a significant survival advantage was found in the hormonal therapy with radiotherapy group compared to the other two groups (p=0.043). CONCLUSION: No significant difference was found between two groups in terms of time until PSA recurrence during our follow-up. In subgroup analysis survival advantage was found in the hormonal therapy with radiotherapy group compared to non-adjuvant and only hormonal therapy groups.

ABSTRACT: Primary renal well-differentiated neuroendocrine tumors (WDNETs), also called renal carcinoids, are extremely rare. Since first described in 1966, approximately 100 cases have been reported in the literature. However, there have been no cases shown by PET/CT to date. We presented a patient with primary renal WDNET who had undergone both 68Ga-DOTATATE PET/CT and 18F-FDG PET/CT for diagnosis and staging. This case illustrated that 68Ga-DOTATATE PET/CT scanning could play a role in the diagnosis, staging, and follow-up of primary renal WDNETs.

Abstract Introduction: Functions attributed to androgens have increased, ranging from the role in hypothalamic-pituitary-gonadal axis and reproductive behaviors to modulation of cognition, mood and some other functions. Sex differences and changes in circulating sex hormones affect human sensory function. In the literature, authors reported this kind of influence for olfaction predominantly in females. Objective: To investigate the effects of low testosterone levels on olfactory functions in males, in this prospective clinical study. Methods: Male patients diagnosed with prostate cancer were included. Thirty-nine patients with prostate cancer whose testosterone levels were lower than 50 ng/dL due to castration, were the study group. Thirty-one patients with prostate cancer who were not castrated with testosterone levels higher than 50 ng/dL were selected as the control group. Acoustic rhinometry and peak nasal inspiratory flow tests were performed for all participants; and for evaluation of olfactory function, both groups completed the Connecticut chemosensory clinical research center olfactory test. Results: The mean ages of the patients and controls were 69.6 ± 7.2 (57-89) and 66.3 ± 5.8 (50-78) years, respectively (= 0.039). There was a significant difference between groups in terms of testosterone levels (p < 0.0001). The multivariate logistic regression revealed testosterone level as the only predictive factor determining the difference between the groups. In terms of olfactory parameters, all scores were lower in the emasculated group (butanol threshold test p = 0.019, identification p = 0.059, and Connecticut center score p = 0.029) There was a significant correlation between testosterone levels and olfactory parameters (p = 0.023; p = 0.025 for identification and Connecticut center scores, respectively). Conclusion: Low testosterone levels in males have negative effects on olfactory functions. Further molecular research is required to understand the connection between testosterone and olfaction.
Resumo Introdução: As funções atribuídas aos andrógenos aumentaram, variam desde o papel no eixo hipotálamo-hipófise-gonadal e comportamentos reprodutivos até a modulação da cognição, humor e outras funções. As diferenças entre os sexos e as mudanças nos hormônios sexuais circulantes afetam a função sensorial humana. Na literatura, os autores relataram esse tipo de influência para o olfato, principalmente no sexo feminino. Objetivo: Investigar os efeitos dos baixos níveis de testosterona nas funções olfativas em homens, neste estudo clínico prospectivo. Método: Pacientes do sexo masculino com diagnóstico de câncer de próstata foram incluídos no estudo. Compreenderam o grupo de estudo 39 pacientes com câncer de próstata cujos níveis de testosterona eram inferiores a 50 ng/dL devido à castração. Foram determinados como grupo controle 31 pacientes com câncer de próstata que não foram emasculados, com níveis de testosterona superiores a 50 ng/dL. Testes de rinometria acústica e pico de fluxo inspiratório nasal foram feitos para todos os participantes; e para avaliação da função olfativa, ambos os grupos concluíram o teste olfativo do Connecticut chemosensory clinical research center. Resultados: A média da idade dos pacientes e controles foi de 69,6 ± 7,2 (57 ± 89) e 66,3 ± 5,8 (50 ± 78) anos, respectivamente (= 0,039). Houve uma diferença significante entre os grupos em relação a níveis de testosterona (p < 0,0001). A regressão logística multivariada revelou o nível de testosterona como o único fator preditivo que determinou a diferença entre os grupos. Em termos de parâmetros olfativos, todos os escores foram menores no grupo castrado (teste do limiar de butanol p = 0,019, identificação p = 0,059 e escore do Connecticut center p = 0,029). Houve uma correlação significante entre o nível de testosterona e os parâmetros olfativos (p = 0,023; p = 0,025 para identificação e escore do Connecticut center, respectivamente). Conclusão: Baixos níveis de testosterona em homens têm efeito negativo na função olfativa. Mais pesquisas moleculares são necessárias para entender a conexão entre testosterona e olfação.

Mucinous adenocarcinoma of the prostate is one of the rare variants of the prostatic carcinoma, and its incidence among all prostatic carcinomas is reported to be 0.3% in the literature. If the tumor variant containing extracellular mucin in <25% of the resected tumor mass, the histology is defined as adenocarcinoma with mucinous features. The mucinous adenocarcinoma of the prostate displays similar prognostic features with the classic adenocarcinoma. In this study, the treatment and surveillance processes of our three patients with prostatic adenocarcinoma with mucinous features were presented along with a literature review.

OBJECTIVE: Micropapillary urothelial carcinoma is an aggressive variant of urothelial carcinoma. Evidence suggests that the relationship between the tumor and inflammatory cells is important in tumor progression and the treatment response. We evaluated the stromal lymphoid response in micropapillary urothelial carcinomas and compared it with conventional urothelial carcinomas. MATERIAL AND METHOD: Among bladder transurethral resection materials diagnosed as 'invasive urothelial carcinoma' between January 2010-March 2017, cases with at least 5% micropapillary urothelial carcinoma were evaluated for age, gender, grade, stage, micropapillary urothelial carcinoma percentage, presence/percentage of accompanying conventional urothelial carcinoma/urothelial carcinoma variants, in situ urothelial carcinoma/micropapillary urothelial carcinoma, lymphovascular invasion, necrosis, and stromal lymphoid response. Stromal lymphoid response was scored as 0-1-2-3. All parameters were evaluated in 50 pure conventional urothelial carcinomas. RESULTS: Among 47 micropapillary urothelial carcinomas, 41 were male. The mean age was 69 years. pT1/pT2 was 23/24. Six cases were pure MPUC. Lymphovascular invasion was present in 8, necrosis in 9 cases. Stromal lymphoid response was present and scored as 1-2-3 in 32 micropapillary urothelial carcinomas (68.1%) and 48 conventional urothelial carcinomas (96%). Micropapillary urothelial carcinomas had significantly higher lymphovascular invasion and pT2 rates and lower stromal lymphoid response. CONCLUSION: Low stromal lymphoid response in micropapillary urothelial carcinomas can be responsible for the poor clinical outcome and impaired response to treatment of these tumors. This is the first study in the English literature to demonstrate a lower stromal lymphoid response rate in micropapillary urothelial carcinomas compared to conventional urothelial carcinomas.

PURPOSE: The aim of this study was to evaluate the diagnostic value of renal pelvis urine Gram staining (RPUGS) in predicting postoperative fever and renal stone culture (RSC) positivity in percutaneous nephrolithotomy (PCNL). METHODS: Totally 141 consecutive patients undergoing PCNL for renal stone were included between January 2018 and December 2019. The RPUGS and renal pelvis urine culture (RPUC) were performed using urine sample from renal collecting system, while RSC was performed using stone fragments. Patients were divided into two groups as Group 1 (n = 119) without postoperative fever (< 38 °C) and Group 2 (n = 22) with postoperative fever (≥ 38 °C). Stone culture and Gram staining models were created for predicting postoperative fever using constant covariates of the presence of residual stone, hydronephrosis, and stone burden. RESULTS: A significantly higher number of patients in Group 2 had RPUGS, RSC, and RPUC positivity (p < 0.001, for each). The sensitivity, specificity, positive predictive value, and negative predictive value of RPUGS in predicting postoperative fever were 72.7%, 89.9%, 57.1%, and 94.7%, respectively. It was observed that both models had similar predictive values and diagnostic performances. Although RSC and RPUGS had a similar diagnostic value in predicting postoperative fever in univariable analysis, both were found to be independent predictors in multivariable analysis (OR: 10.6, 95% CI 4.07-27.9, p < 0.001 and OR: 15.0, 95% CI 5.4-41.2, p < 0.001, respectively). CONCLUSIONS: In conclusion, RPUGS is as effective as RSC in predicting fever after PCNL. We recommend RPUGS during PCNL to manage post-PCNL infectious complications.

PURPOSE: To evaluate the effect of second transurethral resection (TUR) on oncological outcomes, according to the presence or absence of detrusor muscle in the initial TUR of patients with pTa Grade 3/high grade (G3/HG) tumours, who received at least 1 year of maintenance Bacillus Calmette-Guerin (BCG) therapy. PATIENTS AND METHODS: In this retrospective study, we evaluated the effect of second TUR on oncological outcomes of 93 patients with pTa G3/HG tumours, according to the presence or absence of muscle in the initial TUR. All patients received maintenance BCG therapy according to the SWOG protocol. RESULTS: Median follow-up was 36 months. If muscle is present in the initial TUR, a second TUR significantly increased median time to first recurrence, compared to those without a second TUR (77.6 vs 36.9 mos, P = .0086). If muscle is missing in the initial TUR, a second TUR significantly decreased recurrence rate (20% vs 66.7%, P = .002), increased median time to first recurrence (78.9 vs 42.7 mos, P = .0001) and median time to progression (22 vs 7 mos, P = .05), compared to those without a second TUR. CONCLUSION: In patients with pTa G3/HG tumours, if the muscle is missing in the initial TUR, a second TUR should be performed in order to attain lower recurrence rates and longer median time to recurrence and progression. If the muscle is present in the initial TUR, a second TUR will only increase median time to first recurrence.

OBJECTIVES: This study aims to investigatel ongitudinal changes in sexual functions (SF), anxiety status, and health-related quality of life (HRQoL) after shock wave lithotripsy (SWL) in male urolithiasis patients. METHODS: Between February 2015 and April 2017, 85 consecutive male patients with kidney or ureter stones and treated with SWL were included. Patients were evaluated for SF, anxiety status, and HRQoL with questionnaire forms before and at the third month after SWL. Correlation between baseline and third-month scores of International Index of Erectile Function-15 (IIEF-15) subdomains and anxiety was evaluated. Uni- and multivariable linear regression analyses were used to identify changes in IIEF-15 subdomain scores at three months. RESULTS: Mean age was 42.80 ± 9.42 years. Significantly decreased IIEF-15 subdomain scores, increased anxiety and Short Form-36 (SF-36) subdomain scores were achieved at three months (p<0.05, for each). The baseline median values of erectile function (IIEFEF), orgasmic function (IIEF-OF), sexual desire (IIEF-SD), intercourse satisfaction (IIEF-IS), and overall satisfaction (IIEF-OS) were 26, 9, 8, 12, and 8, respectively. The same scores were 26, 9, 6, 9, and 8 at month 3, respectively. According to multivariable analysis, the difference in Beck Anxiety Inventory (BAI) scores was an independent risk factor for both changing in IIEF-SD and IIEF-IS (b= -0.094, 95%CI: -0.179 - -0.009, p=0.030 and b= -0.197, 95%CI: -0.350 - -0.044, p=0.012, respectively). The difference in the State Anxiety (STAISA) scores was an independent risk factor for changing in IIEF-IS (b= -0.075, 95%CI: -0.146 - -0.004,p=0.039). CONCLUSIONS: SWL may lead to impaired SF related to treatment-driven anxiety and significantly improve HRQoL of male patients in short term.
OBJETIVO: Este estudio tiene como objetivo investigar los cambios longitudinales en la función sexual, estado de ansiedad y calidad de vida después de la litotricia extracorpórea en pacientes varones conlitiasis. MÉTODOS: Entre febrero 2015 y abril 2017, 85 pacientes varones consecutivos con litiasis renales o ureterales tratados con litotricia extracorpórea fueron incluidos. Los pacientes fueron evaluados en relación a la función sexual, estado de ansiedad, y calidad de vida con cuestionarios de calidad de vida antes y a los 3 meses de la litotricia extracorpórea. Correlación entre los resultados de International Index of Erectile Function-15 (IIEF-15) iniciales y a los 3 meses en los dominios de ansiedad, fueron evaluados. Análisis de regresión univariada y multivariada fue utilizada para identificar cambios en IIEF-15 a los 3 meses. RESULTADOS: La edad media fue de 42,80 ± 9,42 años. Una caída significativa de los resultados de los subdominios de IIEF-15 con incremento de la ansiedad y Short Form-36 (SF-36) fueron conseguidos a los 3 meses (p<0,05, para cada uno). Los resultados medios en función eréctil (IIEF-EF), función orgásmica (IIEF-OF), deseo sexual (IIEF-SD), satisfacción en las relaciones (IIEF-IS), y satisfacción general (IIEF-OS) fueron 26, 9, 8, 12, y 8, respectivamente. Los mismos resultados fueron 26, 9, 6, 9, y 8 a los 3 meses, respectivamente. En el análisis multivariado, la diferencia en Beck Anxiety Inventory (BAI) fue un factor de riesgo independiente para ambos, cambiando en IIEF-SD y IIEF-IS (b= -0,094, 95%CI: -0,179 -0,009, p=0,030 y b= -0,197, 95%CI: -0,350 -0,044, p=0,012, respectivamente). La diferencia en el State Anxiety (STAI-SA) fue un factor de riesgo independiente para cambio en IIEF-IS (b= -0,075, 95%CI: -0,146 -0,004, p=0,039). CONCLUSIONES: La litotricia extracorpórea comporta cierto grado de disfunción sexual relacionada con la ansiedad del tratamiento y mejora significativamente la calidad de vida en los pacientes varones a corto plazo.

OBJECTIVES: This study aims to investigate longitudinal changes in sexual functions (SF), anxiety status, and health-related quality of life (HRQoL) after shock wave lithotripsy (SWL) in male urolithiasis patients. METHODS: Between February 2015 and April 2017, 85 consecutive male patients with kidney or ureter stones and treated with SWL were included. Patients were evaluated for SF, anxiety status, and HRQoL with questionnaire forms before and at the third month after SWL. Correlation between baseline and third-month scores of International Index of Erectile Function-15 (IIEF-15) subdomains and anxiety was evaluated. Uni- and multivariable linear regression analyses were used to identify changes in IIEF-15 subdomain scores at three months. RESULTS: Mean age was 42.80 ± 9.42 years. Significantly decreased IIEF-15 subdomain scores, increased anxiety and Short Form-36 (SF-36) subdomain scores were achieved at three months (p < 0.05, for each). The baseline median values of erectile function (IIEFEF), orgasmic function (IIEF-OF), sexual desire (IIEF-SD), intercourse satisfaction (IIEF-IS), and overall satisfaction (IIEF-OS) were 26, 9, 8, 12, and 8, respectively. The same scores were 26, 9, 6, 9, and 8 at month 3, respectively. According to multivariable analysis, the difference in Beck Anxiety Inventory (BAI) scores was an independent risk factor for both changing in IIEF-SD and IIEF-IS (b= -0.094, 95%CI: -0.179 - -0.009, p = 0.030 and b= -0.197, 95%CI: -0.350 - -0.044, p = 0.012, respectively). The difference in the State Anxiety (STAISA) scores was an independent risk factor for changing in IIEF-IS (b= -0.075, 95%CI: -0.146 - -0.004, p = 0.039). CONCLUSIONS: SWL may lead to impaired SF related to treatment-driven anxiety and significantly improve HRQoL of male patients in short term
OBJETIVO: Este estudio tiene como objetivo investigar los cambios longitudinales en la función sexual, estado de ansiedad y calidad de vida después de la litotricia extracorpórea en pacientes varones con litiasis. MÉTODOS: Entre febrero 2015 y abril 2017, 85 pacientes varones consecutivos con litiasis renales o ureterales tratados con litotricia extracorpórea fueron incluidos. Los pacientes fueron evaluados en relación a la función sexual, estado de ansiedad, y calidad de vida con cuestionarios de calidad de vida antes y a los 3 meses de la litotricia extracorpórea. Correlación entre los resultados de International Index of Erectile Function-15 (IIEF-15) iniciales y a los 3 meses en los dominios de ansiedad, fueron evaluados. Análisis de regresión univariada y multivariada fue utilizada para identificar cambios en IIEF-15 a los 3 meses. RESULTADOS: La edad media fue de 42,80 ± 9,42 años. Una caída significativa de los resultados de los subdominios de IIEF-15 con incremento de la ansiedad y Short Form-36 (SF-36) fueron conseguidos a los 3 meses (p < 0,05, para cada uno). Los resultados medios en función eréctil (IIEF-EF), función orgásmica (IIEF-OF), deseo sexual (IIEF-SD), satisfacción en las relaciones (IIEF-IS), y satisfacción general (IIEF-OS) fueron 26, 9, 8, 12, y 8, respectivamente.

OBJECTIVES: To compare the urinary NGAL levels with serum creatinine levels as an early biomarker for renal injury in rats with bladder outlet obstruction (BOO). METHODS: Twenty male Wistar Albino rats divided into 4 groups. In each group basal serum creatinine and urinary NGAL levels were evaluated. In Group 1 (Sham/Control group) only laparotomy was performed. In Group 2 (14th day partial BOO) and Group 3 (28th day partial BOO) partial obstruction and in Group 4 (Complete BOO) complete obstruction was performed. Serum creatinine levels and urinary NGAL levels were evaluated in Group 4 on the third day of the study, in Group 2 on the 14th day and in Group 3 and Group 1 on the 28th day. Urethra, ureters and kidneys were excracted by laparotomy and evaluated for histopathologic examination. RESULTS: The increase in plasma creatinine levels after obstruction was statistically significant in Group 4 (p < 0.05). There was significant difference between the groups in urinary NGAL levels after obstruction (p < 0.05). Post-obstruction urinary NGAL levels was highest in Group 4 and it was statistically significant when compared to beginning levels (p < 0.05). In Group 3, increase in urinary NGAL levels were higher (p < 0.05) with no increase in plasma creatinine levels after obstruction. CONCLUSIONS: It can be concluded that urinary NGAL levels might be an early biomarker for renal dysfunction in partial bladder outlet obstruction which may cause renal impairment through upper urinary tract injury. Therefore, urinary NGAL may play role during the treatment choice and follow-up in BOO patients
OBJETIVOS: Comparar los niveles urinarios de NGAL con la creatinina sérica como marcador precoz de daño renal en ratas con obstrucción del tracto urinario inferior. MÉTODOS: 20 ratas Wistar Albino masculinas fueron divididas en 4 grupos. En cada grupo se midió el nivel basal de creatinina en suero así como los niveles urinarios de NGAL. En el grupo 1 (Sham/Grupo Control) solo se realizó laparotomía. En el grupo 2 (14 días después de una obstrucción tracto urinario inferior parcial) y el grupo 3 (28 días después de una obstrucción tracto urinario inferior parcial) se realizó una obstrucción parcial y en el grupo 4 (obstrucción completa) una obstrucción completa. Los niveles de creatinina sérica y NGAL urinario fueron evaluados en el grupo 4 en el 3er día del estudio; en el grupo 2 en el día 14 del estudio y en el grupo 1 en el día 28. Uretra, uréteres y riñones se quitaron por laparotomía y se hizo un análisis histológico. RESULTADOS: El incremento en la creatinina sérica después de la obstrucción fue estadísticamente significativo en el grupo 4 (p < 0,05). Hubo suficiente diferecia entre los grupos en términos de NGAL urinario después de la obstrucción (p < 0,005). Los niveles de NGA post-obstructivos fueron superiores en el grupo 4 y fue estadísticamente significativo en comparación con los niveles iniciales. En el grupo 3, el incremento en los niveles de NGAL urinario fue superior (p < 0,005) sin incrementeo en los niveles de creatinina en plasma después de la obstrucción. CONCLUSIONES: Se puede concluir que los niveles de NGAL urinarios podrían ser un marcador de lesión renal en caso de obstrucción parcial del tracto urinario inferior. Por tanto, NGAL urinario debe jugar un papel durante la elección de tratamiento y seguimiento de pacientes con obstrucción del tracto urinario inferior

OBJECTIVES: The aim of this study was to evaluate relationship between preoperative Prognostic Nutritional Index (PNI) values and tumor stage and to identify predictive value of PNI in patients with primary bladder cancer (BC). METHODS: A total of 164 patients with primary bladder cancer were retrospectively analyzed using institutional bladder cancer database between January 2008 and January 2018. The PNI was calculated using preoperative blood sample results. According to pathological results, the patients were divided into groups as pTa (n=94), pT1 (n=54), and pT2 (n=16) and further into subgroups as Group 1 (pTa patients, n=94) and Group2 (pT1 + pT2 patients, n=70). Subgroups were compared statistically in terms of PNI values and independent risk factors were evaluated using Backward Step wise multivariate logistic regression analysis. RESULTS: Of patients, 145 (88.4%) were males and 19 (11.6%) were females with a mean age of 66.46±10.57 (range, 36 to 93) years. Mean total peripheral lymphocyte count was 2.11±0.71 (×109/L), mean serum albumin was 4.11±0.53 (gr/dL), and mean PNI score was 51.66±6.36. There was a statistically significant difference in serum albumin levels and PNI scores according to tumor stages (p=0.008 and p=0.003, respectively). There was a statistically significant difference in mean serum total protein, albumin, and PNI scores (p<0.01, for all). Tumor size, tumor grade, PNI, carcinoma in situ,and atypical variant status were independent risk factors for predicting tumor stage. CONCLUSIONS: Our study results demonstrate that PNI is a potential preoperative predictor of tumor stage and is an independent risk factor for predicting tumor stage in patients with primary bladder cancer. Lower PNI levels are associated with high stage disease.
OBJETIVOS: El objetivo de este studio fue evaluar la relación entre el índice pronóstico nutricional (IPN) y el estadio tumor para identificar el valor predictivo de IPN en paciente con cáncer vesical primario.MÉTODOS: 164 pacientes fueron incluidos con cáncer vesical primario fueron retrospectivamente evaluados utilizando una base de datos institucional entre enero de 2008 y enero 2018. El IPN fue calculado utilizando la analítica preoperatoria. De acuerdo con los resultadosde la anatomía patológica, los pacientes se repartieron en varios grupos: pTa (n=94), pT1 (n=54) y pT2 (n=16) y después en subgrupos como Grupo 1 (pTa n=94),Grupo 2 (pT1+pT2, n=70). Los subgrupos se compararon en términos de IPN y factores independientes de riesgo se calcularon utilizando Regresión Logística. RESULTADOS: 145 pacientes (88%) fueron hombres y 19 (11%) fueron mujeres con una mediana de edad de 66+/- 11 años (rango 36-93). El recuento total de linfocitos fue de 2,1+/- 0,71 (x109/L, al albumina sérica fue de 4,1+/-0,53 (gr/dL), y la mediana IPN fuede 51. Se observaron diferencias estadísticamente significativas en los niveles de albumina sérica y proteína total y IPN scores (p<0,01) tumoral, IPNm Cis, variantes atípicas fueron factores de riesgo independientes para la predicción del estadio tumoral. CONCLUSIONES: Nuestro estudio demuestra que IPN es un factor predictor potencial del estadio tumoral y un factor independiente de riesgo para la predicción del estadio tumoral en pacientes con cáncer de vejiga.Niveles bajos de IPN se asocian con estadios mas avanzados.
