Can the Mayo Adhesive Probability Score Predict Perioperative Outcomes in Laparoscopic Total and Partial Adrenalectomy?

Objective: This study aimed to determine whether the Mayo adhesive probability (MAP) score could predict perioperative outcomes in transperitoneal laparoscopic total adrenalectomy (LTA) and laparoscopic partial adrenalectomy (LPA). Materials and Methods: The clinical data of 139 patients who underwent transperitoneal LTA (n = 116) or LPA (n = 23) between March 2013 and September 2022 were retrospectively analyzed. According to the images obtained from preoperative contrast-enhanced computed tomography or magnetic resonance imaging, the patients were divided into two groups: the low MAP score group (0-1 points) and the high MAP score group (2-5 points). General clinical features and perioperative outcomes were compared between the groups. Results: In patients with a high MAP score, the mean body mass index (BMI) (p: 0.005), tumor size (p: 0.005), operative time (p: 0.002), estimated blood loss (EBL) (p: 0.001), and complication rate (p: 0.013) were significantly higher compared with those with a low MAP score. The comparison of the patients between the LTA and LPA subgroups revealed that operative time and EBL were significantly higher in both subgroups among the patients with a high MAP score. Moreover, the complication rate in the LTA subgroup was significantly higher in the high MAP score group compared with the other group. The Multivariate analyses revealed that a high MAP score was a risk factor for prolonged operative time (Odds Ratio [OR]: 3.081, 95% Confidence Interval [CI]: 1.284-7.398, p: 0.012), increased EBL (OR: 2.495, 95% CI: 1.114-5.588, p: 0.026), and complications (OR: 6.085, 95% CI: 1.532-24.171, p: 0.01) Conclusions: Patients with a high MAP score had a prolonged operative time, increased EBL, and a higher complication rate compared with those with a low MAP score. In addition, we found that a high MAP score was an independent risk factor for perioperative parameters and complications in patients who underwent LTA and LPA.

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.

Can HALP score, a new prognostic tool, take the place of traditional scoring systems in Fournier's gangrene?

PURPOSE: Fournier's Gangrene (FG) is a fatal condition, therefore prognosis prediction is a crucial step before treatment planning. We aimed to investigate the predictive value of Hemoglobin, Albumin, Lymphocyte and Platelet (HALP) score which is frequently employed in vascular disorders and malignancies, on disease severity and survival in FG patients and to compare HALP score with well-known scoring systems on this aspect. MATERIALS AND METHODS: Eighty-seven men who had surgical debridement for FG between December 2006 and January 2022 were included in this study. Their symptoms, physical examination findings, laboratory tests, medical histories, vital signs, extent and timing of the surgical debridement and antimicrobial therapies were noted. The HALP score, Age-adjusted Charlson Comorbidity Index (ACCI) and Fournier's Gangrene Severity Index (FGSI) were evaluated for their predictive values for survival. RESULTS: FG patients were grouped as survivors (Group 1, n = 71) and non-survivors (Group 2, n = 16) and the results were compared. The mean ages of survivors (59 ± 12.55 years) and non-survivors (64.5 ± 14.6 years) were similar (p = 0.114). The median size of necrotized body surface area was 3% in Group 1 and 4.8% in Group 2 (p = 0.013). On admission, hemoglobin, albumin and serum urea levels and white blood cell counts were significantly different in two study groups. Two study groups were similar for HALP scores. However, ACCI and FGSI scores were greater significantly in non-survivors. CONCLUSIONS: Our results indicated that HALP score does not predict a survival successfully in FG. However, FGSI and ACCI are successful outcome predictors in FG.

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.

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.

Does total knee arthroplasty affect overactive bladder symptoms in female patients?

INTRODUCTION AND HYPOTHESIS: In the current study we hypothesized that total knee arthroplasty might improve the overactive bladder symptoms by providing pain relief and improving physical function. METHODS: One hundred patients who underwent total knee arthroplasty were preoperatively evaluated for overactive bladder and 47 patients that met inclusion criteria were included in this study. All the patients included in the study were assessed both preoperatively and at the 3rd month postoperatively using the Overactive Bladder-Validated 8 (OAB-V8) questionnaire for overactive bladder symptoms, the Oxford Knee Score (OKS) for pain and physical function, and the International Physical Activity Questionnaire-Short Form (IPAQ-SF) for physical activity. RESULTS: The mean age of the patients was 65.4 ± 7 (56-83) years. The OAB-V8, OKS and IPAQ-SF scores significantly improved at the 3rd month postoperatively compared with the initial assessment. All the OAB-V8 domains, namely, frequency, urgency, nocturia, and urgency urinary incontinence, significantly improved following total knee arthroplasty. CONCLUSIONS: Our results showed that following total knee arthroplasty, overactive bladder questionnaire scores significantly improved at the 3rd month postoperatively.

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.

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 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.

Retrograde intrarenal surgery of renal stones: a critical multi-aspect evaluation of the outcomes by the Turkish Academy of Urology Prospective Study Group (ACUP Study).

AIMS: To outline and evaluate the incidence, management and follow-up of the residual fragments (RFs) following retrograde intrarenal surgery (RIRS) of renal stones by the Turkish Academy of Urology Prospective Study Group (ACUP Study). METHODS: Following the ethical committee approval, 15 centers providing data regarding the incidence, management, and follow-up of RFs after RIRS were included and all relevant information was recorded into the same electronic database program ( https://acup.uroturk.org.tr/ ) created by Turkish Urology Academy for Residual Stone Study. RESULTS: A total of 1112 cases underwent RIRS for renal calculi and RFs were observed in 276 cases (24.8%). Of all the parameters evaluated, our results demonstrated no statistically significant relation between preoperative DJ stenting and the presence of RFs (χ2 (1) = 158.418; p = 0.099). RFs were significantly higher in patients treated with UAS (82 patients, 29.3%) during the procedure compared to the cases who did not receive UAS (194 patients, 23.3%) (χ2 (1) = 3.999; p = 0.046). The mean period for a secondary intervention after RIRS was 28.39 (± 12.52) days. Regarding the procedures applied for RF removal, re-RIRS was the most commonly performed approach (56%). CONCLUSIONS: Despite the reported safe and successful outcomes, the incidence of RFs is higher, after the RIRS procedure particularly in cases with relatively larger calculi. Such cases need to be followed in a close manner and although a second flexible ureteroscopy is the treatment of choice for fragment removal in the majority of these patients, shock wave lithotripsy and percutaneous nephrolithotomy may also be preferred in selected cases.

Is Thiol/Disulphide homeostasis important in prostate cancer diagnosis? / Es importante la homeostasis del Tiol/Disulfito en el diagnóstico del cáncer de próstata?

OBJECTIVES: To assess the relationship between prostate cancer and thiol/disulphide homeostasisas an important indicator of oxidative stress. METHODS: After ethics committee approval (546/2015); 388 patients aged between 46-75 years who underwent transrectal ultrasound guided prostatebiopsy in three different centers between July 2015-2016 owing to serum prostate specific antigen (PSA) levels ≥2.5 ng/ml and/or abnormal digital rectal examination were involved in this study. The plasma levels of thiol/disulphide homeostasis parameters were compared in patients with and without prostate cancer. RESULTS: The mean age of the patients was 62.9±7 years. In patients with prostate cancer (n=130, 33.5% ) the mean plasma levels of native thiol and total thiol were lower (332.9 vs 362.1 µmol/L and 363 vs 392.6 µmol/L, p=0.001). Plasma disulphide levels were not statistically different between the groups (15 vs 15.3 µmol/L, p=0.936). In prostate cancer group; patients with Gleason score ≥7 had lower plasma native thiol levels than patients with Gleason score<7 (321.3  vs 342.6 µmol/L, p=0.029) while there were no significant differences in total thiol and disulphide levels (352.3 vs 371.9 µmol/L, ptotal Thiol =0.064 and 15.5 vs 14.6 µmol/L, pdisulphide =0.933). CONCLUSIONS: Lower plasma levels of thiol in patients with prostate cancer and high Gleason score is an oteworthy result. We believe that our results should be supported by further studies.

OBJETIVOS: Establecer la relación entre cáncer de próstata y la homeostasis del tiol/disulfito como un importante indicador de estrés oxidativo.MÉTODOS: Con la aprobacion del comité ético (546/2015), 388 pacientes entre 46 y 75 años que recibieron una biopsia transrectal prostática ecoguiada en diferentes centros entre julio 2015 y 2016 por un PSA superior a 2,5 ng/ml o tacto rectal anómalo, fueron incluidos en este estudio. Los niveles plasmáticos de la homeostasis de tiol/disulfito se compararon en pacientes con y sin cáncer de próstata. RESULTADOS: La edad media de los pacientes fue de 62,9 =/- 7 años. En pacientes con cáncer de próstata (n=130, 33,5%) el nivel plasmático de tiol nativo y tiol total fue menor (332,9 vs 362,1 µmol/L y 363 vs 392,6 µmol/L, p=0,001). Los niveles de disulfito en plasma no fueron estadísticamente diferentes entre los grupos (15 vs 15,3 µmol/L, p=0,936). En el grupo con cáncer de próstata; pacientes con Gleason 7 o más tuvieron niveles menores de tiol nativo en relación a los pacientes con Gleason menor de 7 (321,3 vs 342,6 µmol/L, p=0,029), mientras no hubo diferencias en eltiol total y los disulfitos (352,3 vs 371,9 µmol/L, ptotaltiol =0,064 y 15,5 vs 14,6 µmol/L, pdisulfito =0,933). CONCLUSIONES: Niveles bajos de tiol en pacientes con cáncer de próstata y Gleason alto es un resultado notable. Creemos que nuestros resultados deberian tenerse en cuenta para otros estudios.

Comparison of the efficacy of desmopressin fast-melting formulation and enuretic alarm in the treatment of monosymptomatic nocturnal enuresis.

BACKGROUND: Primary monosymptomatic nocturnal enuresis (MNE) is a common pediatric condition and there are two firstline, evidence-based treatments available; desmopressin and the enuresis alarm. Although there are many studies comparing enuresis alarm and desmopressin treatments in the literature, most were conducted using old formulations of desmopressin. OBJECTIVE: To compare the efficacy of desmopressin MELT formulation and enuresis alarm therapy in patients with MNE. STUDY DESIGN: A total of 130 patients who had primary MNE were included in the study. The patients were divided into two groups using simple randomization; desmopressin MELT (Group 1, n = 66) and enuresis alarm (Group 2, n = 64). The patients were invited for a follow-up visit at the fourth, 12th and 24th weeks of treatment. Treatment response and compliance were evaluated using bed-wetting diary and ICSS criteria. RESULTS: The mean age of the patients Group 1 and 2 was 11.2 + 3.3 and 10.2 + 3.4 years, respectively (p = 0.104). Complete response rate was similar at 4th week (53% vs. 37.3%, p = 0.162) and at 12th week (68.4% vs. 68.2%, p = 0.257). The relapse rate was significantly higher in the desmopressin MELT group than in the enuresis alarm group (48.9% vs 20.5%, p = 0.007). At the end of the study ten patients were excluded from the study because of loss to follow-up and/or side effects. The overall complete response rate was significantly higher in the enuresis alarm group than in the desmopressin MELT group at the end of the study (41.3% vs 64.9%, p = 0.035). When the intention to treat analysis population was considered, similarly the complete response rate was significantly higher in the enuresis alarm group than in the desmopressin MELT group (40.9% vs 64.1%, p = 0.027). DISCUSSION: With regard to the management of children with MNE, our study revealed that desmopressin MELT and enuresis alarm both have high efficacy rates in primary MNE treatment both at 4th and 12th week. However, overall complete response rate was better in enuresis alarm treatment at 24th week. In addition, enuresis alarm treatment also presents as a more favorable relapse rate. CONCLUSIONS: Enuresis alarm presented a more permanent treatment response and a lower relapse rate than desmopressin MELT formulation.

Comparison of the treatment efficacies of paroxetine, fluoxetine and dapoxetine in low socioeconomic status patients with lifelong premature ejaculation.

INTRODUCTION: To assess the treatment efficacies of paroxetine, fluoxetine and dapoxetine in patients with lifelong premature ejaculation (PE). MATERIAL AND METHODS: One hundred and seventy male patients with lifelong PE were included in our study. Premature ejaculation profile (PEP) and Intravaginal ejaculation latency times (IELT) were recorded. Paroxetine 20 mg/d was given in Group 1 (n = 64), fluoxetine 20 mg/d was given in Group 2 (n = 47) and dapoxetine 30 mg on demand (at least two times/week) was given in Group 3 (n = 59) patients. After 1 month of treatment, the patients' IELT, PEP and patient reported clinical global impression of change (CGIC) were completed. RESULTS: The mean age was 36 ±9.2 years. There was no difference between the groups' age, PEP and IELT before treatment (p >0.05). PEP and IELT improved in all three groups (p <0.001). The changes in the 1st and 3rd questions of PEP was significantly higher in group 1 than in the other groups (pPEP-1 = 0.042, pPEP-3 = 0.001). The changes in the 2nd and 4th questions of PEP were similar between groups (pPEP-2 = 0.444, pPEP-4 = 0.442). In group 1 and 3 IELT changes were better than group 2 (pIIEL1-3 = 0.297, pIIEL1-2 = 0.017, pIIEL2-3 = 0.100). There was no difference between CGIC scores (p = 0.087). The treatment was terminated by 8 patients in Group 1 and 9 patients in Group 2 because of side effects. CONCLUSIONS: While paroxetine treatment seemed to be better than the other medications, dapoxetine 30 mg treatment has less side effects than the two others and its' on demand usage makes it more prominent than the others.

Safety and reliability of fluoroscopy-free technique in retrograde intrarenal surgery.

BACKGROUND: Traditional retrograde intrarenal surgery is performed under fluoroscopic guidance. In the present study, we assessed the efficacy and safety of retrograde intrarenal surgery without fluoroscopic guidance in selected patients with renal and proximal ureteral stone disease. METHODS: Between October 2013 and August 2016, a total of 350 patients who underwent retrograde intrarenal surgery for upper urinary tract stone disease were retrospectively analyzed. Ninety-five (Group 1) and 255 (Group 2) patients underwent retrograde intrarenal surgery with and without fluoroscopy guidance, respectively. We documented complications and success rates of the procedures retrospectively. RESULTS: The mean age of the patients was 45.3 years. The mean stone size was 14.5±5.5 (5-30) mm and 13.7±5.2 (4-30) mm in Group 1 and 2, respectively (P=0.197). The stone-free rates one month after surgery were 86.3% and 87% in Group 1 and 2, respectively (P=0.739). The overall incidence of intraoperative complication was 16.3%. In Group 1, incidence of intraoperative complication was 17.9% (N.=17) while in Group 2 incidence was 15.7% (N.=40) (P=0.620). The overall postoperative complication rate was 5.1%. Postoperative complications developed in seven patients (7.4%) in Group 1 and in 11 patients (4.3%) in Group 2 (P=0.250). CONCLUSIONS: Fluoroscopy-free retrograde intrarenal surgery seems to be technically feasible and safe for the treatment of renal and proximal ureteral stone disease in uncomplicated selected cases.
