Is there an association between a high monocyte/high-density lipoprotein cholesterol ratio and recurrence of urethral stricture after internal urethrotomy?

INTRODUCTION: Internal urethrotomy (IU) has been the most commonly used procedure for the treatment of urethral strictures (US) since it was described by Scahse in 1974. Although simple to perform and associated with a short recovery time, the main disadvantage is the high recurrence rate of stenosis. At present, there are no markers available for the prediction of recurrence after IU. The aim of this study was to evaluate the correlation between MHR and recurrence rates. METHODS: The data of a total of 250 male patients who underwent IU for the first time for bulbar urethral stricture less than 2cm in our hospital between January 2011 and January 2019 were retrospectively analysed. The MHR was calculated as the ratio of monocytes to HDL-C. RESULTS: In all, 78 patients experienced a recurrence while the remaining 177 did not. The stricture recurrence rate was recorded as 31.2% at the 3-year follow-up. There was a statistically significant difference in stricture length and MHR (P=0.015 and 0.001 respectively). MHR was high in the recurrent group. As a result of the Chi-square test, the positive predictive values (PPV) and negative predictive values (NPV) were 65.3% and 89.7%, respectively. ROC analysis was used to determine the optimal cut-off value. The cut-off value was found to be 1.72. CONCLUSION: In our opinion, a high MHR may indicate the presence of immune inflammation and it can be used as a prognostic factor for stricture recurrence after IU.

Efficacy of Aspiration-Assisted Ureteral Access Sheath (ClearPETRA) in Retrograde Intrarenal Surgery.

Backgrounds: In the renal intrarenal stone surgery (RIRS) procedure, ureteral access sheath (UAS) is still used in the majority of surgeries to both protect the flexible ureteroscope (FURS) and reduce intrarenal pressure. ClearPETRA is a new UAS that has an integrated aspiration port. We aimed to evaluate the clinical outcomes and effectiveness of Aspiration-Assisted UAS (ClearPETRA) in the RIRS procedure. Methods: One thousand six hundred twenty patients who underwent RIRS between January 2021 and January 2024 were evaluated retrospectively and 512 patients were included in the study. According to stone size, patients with stones less than 2 cm and those with stones between 2 and 3 cm were analyzed separately. Patient's demographic data, stone size, body mass index, Extracoporeal Shockwave Lithotripsy (ESWL) history, stone side, stone density (Hounsfield Unit), operation time, stone-free rate (SFR), and the number of patients with sepsis were recorded. SFR was evaluated with kidney urinary bladder 3 months after surgery for opaque calculi. Nonopaque calculi patients were evaluated with noncontrast computed tomography 3 months after surgery. In the postoperative evaluation, patients with stones less than 4 mm were evaluated as SFR. P value of <0.01 was considered statistically significant. Results: Patient's demographic data, stone characteristics, and history of ESWL were similar in the ClearPETRA and UAS groups (P > .05). A total of 328 patients who underwent RIRS for stones less than 2 cm were included (80 ClearPETRA, 248 UAS). Length of hospital stay, operation time, SFR, secondary intervention, or postoperative sepsis (P ≥ .01) were similar in both groups. The incidence of postoperative fever was statistically significantly lower in the ClearPETRA group (P = .006). A total of 184 patients who underwent RIRS for stones between 2 and 3 cm were included (42 ClearPETRA, 142 UAS). In the ClearPETRA group, operation time was statistically significantly shorter (P = .002), SFR was statistically significantly higher (P = .003), and the number of fever and sepsis were statistically significantly less (P = .003 and 0.002, respectively). Conclusion: We found that ClearPETRA reduces the likelihood of postoperative fever after RIRS surgeries. Moreover, we can say that the use of ClearPETRA in RIRS, especially for stones larger than 2 cm, reduces the operation time, increases the SFR, and also reduces sepsis rates.

Systemic Inflammatory Index: A Promising Non-Invasive Marker for the Prediction of Response to Neoadjuvant Chemotherapy prior to Cystectomy.

INTRODUCTION: The main challenge to the optimal use of neoadjuvant chemotherapy (NAC) is the difficulty in selecting patients who may or may not benefit from NAC. Our aim in this study was to investigate whether the Systemic Inflammatory Index (SII) predicts response to chemotherapy in patients who receive NAC prior to cystectomy. METHODS: We retrospectively analysed the data of patients who underwent NAC followed by cystectomy at our institution between January 2010 and September 2015 and whose 5-year follow-up was completed. All patients who underwent diagnostic biopsy with complete transurethral resection of bladder tumour at our hospital and whose pathology result was muscle-invasive transitional cell carcinoma were included in the study. At least 3 courses of gemcitabine/cisplatin NAC were given to all patients. A pathological response was defined as a reduction in cystectomy to a lower pathological stage after NAC. RESULTS: The SII was 320.8 ± 51 in the responders and 388.28 ± 50 in the non-responders. SII optimal cut-off of 350 was determined. The sensitivity and specificity of SII in predicting response were found to be 80% and 83%, respectively. Low SII (<350) was found to be a significant predictor of response compared with the other factors on multivariate analysis. The mean overall survival time was 55.4 months in patients with a low SII value and 40.3 months in the high SII group. CONCLUSION: SII, together with known clinicopathological factors and newer genetic and molecular markers, can be used to select patients for NAC.

Hybrid technique has lower stricture rates than Wallace and Bricker.

INTRODUCTION: A clear consensus has not yet been reached on the optimal ureteroenteric anastomosis technique for ileal conduit urinary diversion following radical cystectomy. This study aims to determine the incidence of strictures and their management associated with these anastomosis techniques. METHODS: We conducted a retrospective, single-center study of patients who underwent radical cystectomy and urinary diversion between March 2014 and August 2022. Patients were categorized based on the ureteroenteric anastomosis technique used: Wallace, Bricker, or Hybrid. Strictures were identified through antegrade pyelography following nephrostomy placement. RESULTS: A total of 141 patients were included in the study, with 60 patients in the Wallace group (42 %), 42 patients in the Bricker group (30 %), and 39 patients in the Hybrid group (28 %). The overall incidence of ureteroenteric strictures was 15 %, with 7 patients in the Wallace group, 11 patients in the Bricker group, and 3 patients in the Hybrid group experiencing strictures. There was no statistically significant difference in stricture rates between the Wallace and Bricker groups (11 % vs. 26 %, p = 0.09) or between the Wallace and Hybrid groups (11 % vs. 7 %, p = 0.73). However, a statistically significant difference was observed between the Bricker and Hybrid groups (26 % vs. 7 %, p = 0.03). The mean time to stricture development was 9.2 ± 3.3 months for the Wallace group, 9.5 ± 3.7 months for the Bricker group, and 12.6 ± 5 months for the Hybrid group (p = 0.407). CONCLUSION: The Hybrid ureteroenteric anastomosis technique exhibits a lower stricture rate compared to the Bricker and Wallace techniques. It represents a safe and feasible alternative technique.

Systemic Inflammatory Index: A Novel Biomarker for Predicting the Progression in Active Surveillance in Patients with Prostate Cancer.

OBJECTIVE: To investigate active surveillance (AS) for patients with prostate cancer to show the systemic inflammatory index (SII) progression and to evaluate whether SII will be an AS criterion in PCa patients. STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Urology, University of Health Sciences, Prof. Dr. Cemil Tascioglu City Hospital, from February 2015 to December 2021. METHODOLOGY: For active surveillance follow-up criteria, patients with prostate cancer who underwent AS with PSA <10 ng/ml, GS ≤6, clinical stage t1c-t2b, ≤2 core positive, and for each positive core had ≤50% tumour cells, were inducted and SII was determined. RESULTS: As a result of the univariate analysis, high SII values, number of cores involved, and length of the tumour in one core significantly affected progression (in order of p = 0.009, B = 1.830, Exp(B) = 6.233, CI [1.58-24.497]; p = 0.018, B = 0.682, Exp(B) = 1.978, CI [1.123-3.482]; p=0.006, B = 1.835, Exp(B) = 6.263 CI [1.692-23.181]). High SII values (>443.42) had better explanations for progression than the number of core involvement but were similar to the length of the tumour in one core. As a result of the multivariate analysis, high SII values (>443.42) and the tumour 's length in one core had similar effects on progression (in order of p = 0.011, B = 1.978, Exp(B) = 7.227, CI [1.570-33.269]; p = 0.009, B = 1.958, Exp(B) = 7.084, CI [1.642-30.555]). CONCLUSION: Th use of SII early in the course of treatment can help to identify which prostate cancer patients can be selected for active treatment instead of active surveillance, and to assess the probability of progression. KEY WORDS: Prostate cancer, Active surveillance, Systemic inflammatory index, Biomarker.

INTRODUCTION: Urinary tract infections are the most common bacterial infections in the older population.

Application of S.T.O.N.E. Nephrolithometry Score for Prediction of Stone-Free Status and Complication Rates in Patients Who Underwent Percutaneous Nephrolitotomy for Renal Stone.

Background: Renal stone disease is a common disorder in urology practice. Kidney stone has various treatment methods such as extracorporeal shock wave lithotripsy, retrograde intrarenal surgery, and percutaneous nephrolithotomy (PCNL). In this study, we aimed to determine the value of S.T.O.N.E. nephrolithometry score, which is considered as a new scoring system for predicting residual stone rate and complications in patients undergoing PCNL due to renal calculi. Materials and Methods: A total of 120 patients >18 years old who underwent PCNL were evaluated prospectively. Five parameters available from preoperative noncontrast-enhanced computed tomography were measured: stone size (S), tract length (T), obstruction (O), number of involved calices (N), and essence or stone density (E) and then S.T.O.N.E. nephrolithometry score was calculated. The prediction of the stone-free rates and complication rates of this scoring was evaluated statistically. Results: When the age, gender, body mass index, comorbidities, and American Society of Anesthesiologists scores of the patients were evaluated according to the patients' postoperative stone-free status, no statistical difference was found between the groups. Patients had a stone-free rate of 78%. Patients' mean neuropilitometry score was calculated to be 7.75 S.T.O.N.E. nephrolithometry score statistically significant (P = .001) for prediction of stone-free status. S.T.O.N.E. nephrolithometry score was significantly correlated with operation time, estimated blood loss, duration of fluoroscopy, duration of hospital stay, and number of punctures. Complications were seen in 13 patients. Conclusions: S.T.O.N.E. nephrolithometry score can be used as an objective criterion for predicting the complexity of the PCNL process. In addition, this scoring system is expected to provide more objective preoperative counseling and can provide standardization in academic studies.

The impact of myasthenia gravis on lower urinary tract functions.

AIM: To assess the functions of the lower urinary tract (LUT) in patients with myasthenia gravis (MG). MATERIALS AND METHODS: A total of 36 patients (18 males and 18 females) with MG and 29 healthy controls were enrolled. Participants completed a 3-day voiding diary and responded to questionnaires "Overactive Bladder Symptom Score" (OABSS) and "International Consultation on Incontinence-Short Form" (ICIQ-SF). All patients underwent uroflowmetry and ultrasonography (US). The data were compared based on the onset of disease and serological status. RESULTS: The most common urinary symptoms were nocturia (80.5%), incontinence (61%) and urgency (47%). OABSS was higher in patients than controls (P = .008). Duration of urinary symptoms was longer, and nocturia was more common in late-onset MG (LOMG) than in early-onset MG (EOMG; P = .029, P = .023). The duration of disease and urinary symptoms statistically increased in ACh-Ab (-) group compared with ACh-Ab (+) group (P = .003, P = .027). Night-time urination frequency significantly increased while daytime voided volume (VV) decreased in LOMG compared with EOMG (P = .003 and P = .01). Residual volume on the US was significantly higher in LOMG than that in EOMG (P = .004). The duration of disease was positively correlated with tQmax and daytime urination frequency (P = .013, r = .48; P = .016, r = .398). A negative association was found between duration of disease and daytime VV (P = .04, r = -.344). CONCLUSION: LUT dysfunction may manifest disease in MG, particularly in late-onset forms. The lack of ACh-Ab seemed to prolong the duration of disease and urinary disturbances.

Our laparoscopic cystectomy experiences.

PURPOSE: We aimed to present our laparoscopic cystectomy experience and demonstrate that it is a feasible technique with safe oncologic principles. METHODS: Total 19 patients who underwent laparoscopic radical cystectomy and pelvic lymph node dissection (PLND) in our urology clinic (Okmeydani Training and Research Hospital) were retrospectively evaluated. Demographic data, operation technique and complications, tumour pathology and follow-up details of patients were recorded. RESULTS: Patients ranged from 40 to 73 years, with the average age of 60.8 and female/male rate was 2/17. The mean total operation time was 375 min (range 260-500). Mean hospitalisation time of patients was 10.3 days. The mean follow-up time was 11.2 months. CONCLUSION: Minimally invasive approaches in urology are becoming the first line treatment by the time. Due to the high costs and limited availability, robotic surgery is still not exactly widespread in the world. Our series showed that conventional laparoscopic cystectomy is an appropriate approach until robotic surgery becomes widespread.

Statins are effective in the treatment of benign prostatic hyperplasia with metabolic syndrome.

OBJECTIVE: To compare the efficacy of statins and ɑ blockers drug therapies for benign prostatic hyperplasia (BPH) in patients with metabolic syndrome (MetS). MATERIALS AND METHOD: A total of three hundred patients were randomly distributed into three groups of one hundred patients each. Group 1 received only ɑ-adrenoceptor antagonist (ɑ-blocker, AB) (Tamsulosin), group 2 received only statin (atorvastatin), and group 3 received AB plus statin (Tamsulosin + Atorvastatin). The efficacy measurement was assessed by analyzing the changes from baseline in the total International Prostate Symptom Score (IPSS), disease-specific QoL question score and maximum urinary flow rate at the end of 6 months in each group and between the three groups. RESULTS: Pre-treatment and post-treatment value of triglycerides (TG), high-density lipoprotein (HDL), and prostate volüme (PV) were not significantly different in AB group, while TG and PV were significantly lower in patients taking statin and combined therapy. The significant decrease was demonstrated in maximum urinary flow rate (Qmax) in three groups. However, the most significant decrease was observed in the combination therapy group. IPSS, postvoid residual urine volüme (PVR), and Quality of Life score (QoL) significantly changed in three groups. CONCLUSION: We recommend of the use of statins in those men with BPH accompanied by MetS in which AB is ineffective alone.

Metabolic syndrome is associated worsened erectile function in patients undergoing TURP due to benign prostatic hyperplasia.

INTRODUCTION: Transurethral resection of the prostate (TURP) is the gold standard method for surgical treatment of benign prostatic hyperplasia (BPH). So, the complications of TURP is important, in which erectile dysfunction is the most important. The aim of the present study is to evaluate erectile dysfunction in patients undergoing TURP treatment for BPH and investigate the correlation between metabolic syndrome and erectile dysfunction. MATERIALS AND METHODS: This study included 120 patients who underwent surgery for BPH at Beylikdüzü State Hospital and Okmeydani Training and Research Hospital. IIEF-5 form was administered to the patients before the surgery and six months after the surgery. The Student's t-test, Wilcoxon, and chi-square test were used in the statistical analysis. RESULTS: The patients were investigated by IIEF-5 scoring into three groups (severe, moderate, and non-ED (erectyl disfunction)-mild). The statistical analysis of IIEF-5 form administered to 120 patients who underwent surgery did not show any significant difference before surgery and six months after surgery (p > 0.05). Metabolic syndrome and erectile dysfunction correlation were examined, and a significant correlation was obtained between metabolic syndrome and severe erectile dysfunction (p < 0.05). CONCLUSIONS: IIEF-5 results administered before and after surgery showed no significant difference. The study showed that patients with metabolic syndrome have a higher probability of having erectile dysfunction after TURP compared to patients without metabolic syndrome. Moreover, post-surgery, patients with metabolic syndrome seemed to be affected negatively regarding erectile dysfunction compared to patients with no metabolic syndrome.

The effect of overactive bladder treatment with anticholinergics on female sexual function in women: a prospective observational study.

PURPOSE: The aim of the study was to determine the effect of anticholinergics used for overactive bladder treatment on the sexual function of women. METHODS: Between January 2016 and August 2018, over 18 years old, 216 sexual active women with OAB and 165 healthy women as control group were prospectively enrolled in the study. Five different anticholinergics were used for the treatment. Female Sexual Function Index (FSFI), eight-item overactive bladder awareness tool (OAB-V8), and Beck Depression Inventory form were completed before and after 3 months. Baseline and post-treatment scores were compared with a control group of age-matched healthy women. RESULTS: Patients with OAB reported at baseline significantly worse sexual function in all FSFI domains compared to healthy control group (21.47 ± 3.22 vs. 26.79 ± 5.56, p < 0.01). Three months after treatment, over 85% of participants reported clinically relevant improvements in sexual function, with statistically significant changes in mean FSFI scores. CONCLUSIONS: Treatment of OAB with anticholinergics can improve sexual function of sexual active women with OAB. Patients may be informed about this potential benefit of anticholinergic treatment, to improve their sexual function.

Beneficial effects of Oltipraz, nuclear factor - erythroid - 2 - related factor 2 (Nrf2), on renal damage in unilateral ureteral obstruction rat model

ABSTRACT Introduction: We investigated whether Oltipraz (OPZ) attenuated renal fibrosis in a unilateral ureteral obstruction (UUO) rat model. Materials and Methods: We randomly divided 32 rats into four groups, each consisting of eight animals as follows: Rats in group 1 underwent a sham operation and received no treatment. Rats in group 2 underwent a sham operation and received OPZ. Rats in group 3 underwent unilateral ureteral ligation and received no treatment. Group 4 rats were subjected to unilateral ureteral ligation plus OPZ administration. Transforming growth factor beta-1 (TGF-β1), E-cadherin, nitric oxide (NO) and hydroxyproline levels were measured. Histopathological and immunohistochemical examinations were carried out. Results: TGF-β1, NO and E-cadherin levels in the UUO group were significantly higher than the sham group and these values were significantly different in treated groups compared to the UUO group. In rats treated with UUO + OPZ, despite the presence of mild tubular degeneration and less severe tubular necrosis, glomeruli maintained a better morphology when compared to the UUO group. Expressions of α-SMA in immunohistochemistry showed that the staining positivity decreased in the tubules of the OPZ-treated group. Conclusions: While the precise mechanism of action remains unknown, our results demonstrated that OPZ exerted a protective role in the UUO-mediated renal fibrosis rat model highlighting a promising therapeutic potency of Nrf2-activators for alleviating the detrimental effects of unilateral obstruction in kidneys.

The effect of prostatic inflammation on clinical outcomes in patients with benign prostate hyperplasia.

BACKGROUND: To investigate the effect of asymptomatic inflammatory prostatitis on clinical outcomes of patients undergoing trans urethral resection of prostate due to benign prostatic hyperplasia. MATERIALS AND METHODS: A total of 514 patients were enrolled in the study. Clinical parameters and pathological results were compared before and one year after surgery. RESULTS: Of the patients 310 were diagnosed with purely benign prostatic hyperplasia and the others were diagnosed with both prostatic inflamation (cathegory IV) and benign prostatic hyperplasia. No statistical significance was observed between two groups among the parameters including age, prostate volume and post voiding residue (P > 0.05). Patients with prostate inflammation presented higher preoperative International Prostate Symptom Score and lower Qmax values when compared to those without inflammation before trans urethral resection of prostate. CONCLUSION: Asymptomatic prostate inflammation can lead to worsen lower urinary tract symptoms and urinary flow rate in patients with benign prostatic hyperplasia. Furthermore, the improvement of the complaints after surgery was worse in patients with asymptomatic prostate inflammation. Further well designed prospective-randomised studies are needed to support our findings.

Neuronal Nitric Oxide Synthase Expression in the Anterior Vaginal Wall of Patients with Stress Urinary Incontinence.

PURPOSE: Stress urinary incontinence (SUI) and pelvic organ prolapse (POP) are common medical problems, particularlyamong older women. In this study, we aim to explore the relationship between the neurotransmitter nNOS in the vaginal epithelium, and the occurrence of SUI and changes of nNOS levels according to menopausal status.Matherials and Methods: Fourty women were enrolled. The patients were divided into four groups according to menstruaiton status and SUI. The vagina specimens were taken during transobturator tape application. The specimens were examined pathologically in terms of n-NOS expression. nNOS expression was compared between SUI and control groups. The results were evaluated statistically. RESULT: Epithelial total nNOS score in group 1 and group 3 were 2.4 ± 0.5 and 1.4 ± 0.5 respectively (P = .003). Stromal total nNOS score was found 2.2 ± 0.4 in group 1 and 1.3 ± 0.5 in group 3 (P = .001). Epithelial total nNOS score in group 2 and group 4 were 4.4 ± 0.5 and 3.5 ± 0.5 respectively (P = .003). Stromal total nNOS score was found 4.4 ± 0.5 in group 2 and 3.6 ± 0.5 in group 4 ( P = .006). CONCLUSION: Our results show that expression of nNOs in the anterior vaginal epithelium decreased significantly in the SUI group. Altough our findings indicate important results, well designed further studies are needed to comprehend the role of NOS pathways better in SUI pathophysiology.

Visceral adiposity index is associated with premature ejaculation inversely: a cross-sectional study.

OBJECTIVE: Visceral adiposity index (VAI) is a novel indicator for the assessment of visceral obesity. In this study, we aimed to evaluate the relationship between VAI and premature ejaculation (PE). MATERIALS AND METHOD: A total of 300 men were included in the study. Hundred and fifty men with PE and 150 men without PE (control). All men were evaluated for PE by premature ejaculation diagnostic tool (PEDT). VAI levels were calculated using body mass index (BMI), high density lipoprotein and triglyceride (TG) levels. RESULTS: Mean age of the study groups was 34.3 ± 5.2 (30-60) years and the mean age of the controls were 35.9 ± 5.3 (30-60) years. The men with PE had lower BMI, TG levels, waist circumference (WC) and higher high-density lipoprotein-cholesterol (HDL-C) levels. Mean VAI level was 4.13 ± 0.7 in study group and 5.72 ± 1.6 in control group, respectively. VAI levels were statistically higher in men without PE (p < .001). DISCUSSION: Our cross-sectional study demonstrated a negative correlation between VAI and PE. VAI is superior index for the evaluation and calculation the relationship between obesity and PE.

Comparison of the clinical parameters of benign prostate hyperplasia in diabetic and non diabetic patients.

OBJECTIVE: We evaluated the correlation between benign prostate hyperplasia (BPH) measures and diabetes mellitus in men with benign prostate hyperplasia in a prospective study. MATERIALS AND METHODS: Between 2008-2012, 100 diabetic and 200 non diabetic patients undergoing surgery due to benign prostate hyperplasia were enrolled in the study. The parameters evaluated for each patients included prostate volume, fasting blood glucose, HbA1c, total testosterone, total prostatic specific antigen (T-PSA), triglicerides, total cholesterol and body mass index (BMI). A questionnaire including international prostate symptom score (IPSS) was sdministered and uroflow test measuring the peak urinary flow rate was performed to appreciate the complaints of the patients objectively. RESULTS: Diabetic patients are more likely to have larger prostate volume. The symptom score evaluated by IPSS and post micturition residual volume were also significantly higher in diabetic groups. The other statistically significant different parameter between two groups was total testosterone that diabetic patients tend to have lower levels. Diabetic counterparts were established to have higher BMI. No statistically significant differentiation was observed about trigliceryde and total cholesterol levels and uroflow rates. CONCLUSIONS: Our study suggests a positive correlation between high prostate volume and diagnosis of diabetes mellitus in patients with benign prostatic hyperplasia. We also observed a positive correlation between symptom scores and post micturion residual volumes and diagnosis of diabetes mellitus suggesting that the presence of diabetes is related to both static and dynamic components of benign prostate hyperplasia. Additionally testosterone levels were lower in diabetic patients. Further studies need to confirm these relationship in a larger population.

Effects of Tadalafil 5 mg Dosed Once Daily in Men with Premature Ejaculation.

PURPOSE: In this study, we evaluated the effect of 5 mg tadalafil once daily in men with premature ejaculation (PE). METHODS: Thirty married men with lifelong PE and 30 healthy men as control group were included in this study. All the patients received 5 mg tadalafil once a day for a month. The international index of erectile function questionnaire and intravaginal ejaculatory latency times (IELTs) and PE profile were recorded before and after treatment. Plasma samples were collected before and after treatment. RESULTS: The mean baseline IELTs was 40.8 ± 8.1 s in the PE group and 196.5 ± 26.2 s in the control group. After treatment in the PE group, the mean IELTs values showed a statistically significant improvement from the baseline values. At the end of 4 weeks, in the PE group, the mean IELT values showed a statistically significant improvement from the baseline values. Baseline serum nitric oxide (NO) levels were 27.3 ± 1.7 in the PE group and in the 31.1 ± 1.4 healthy control groups. After treatment, NO levels were increased from baseline. CONCLUSION: We consider that 5 mg tadalafil once daily is safety and effective for the treatment of PE.

Selective Nuclear Factor Kappa b (NFkB) Inhibitor, Pyrrolidium Dithiocarbamate Prevents, Long-Term Histologic Damage in Ischemia-Reperfusion Injuries after Delayed Testicular Torsion.

PURPOSE: Nuclear factor kapa b (NFKB) is a transcription factor that is required for cytokine-mediated induction of the human inducible nitric oxide synthase (iNOS) gene. Recent studies have shown that in the pathophysiology of ischemia-reperfusion (IR) injuries NFKB is involved. In our study we aimed to determine the efficacy of the selective NFKB inhibitor, pyrrolidium dithiocarbamate (PDTC), on long-term histological damage in testicular IR injuries. MATERIALS AND METHODS: Twenty-one adult male Wistar albino rats were divided into 3 equal groups. In groups 1-2, the left testes in rats underwent 4 hours of 720° experimental torsion. In group 2, PDTC (100 mg/kg) was administered intraperitoneally in the last 1 hour before detorsion; and group 3 underwent a sham operation. All rats underwent bilateral orchiectomy 45 days after the experiment. The testes weights were measured and compared to the other groups and their contralateral values. Testes samples were fixed with Bouin solution for histological (Johnsen score) and immunohistochemical examination. Immunohistochemically iNOS and an active subunit of NFKB, p65 were evaluated using mouse primary monoclonal antibodies and were evaluated semi quantitatively. RESULTS: Testicular weights and Johnsen scores in ipsilateral testes were 0.67 ± 0.85, 1.54 ± 0.11, 1.84 ± 0.64 and 1.63 (1-4), 6.94 (4-10), 5.29 (1-9) in the torsion, sham and PDTC groups, respectively. In contralateral testes the same values were 1.74 ± 0.84, 1.59 ± 0.13, 1.50 ± 0.54 and 5.38 (2-8), 7.17 (5-10), 6.30 (4-9). Testicular weights and Johnsen scores were significantly different in the ipsilateral torsion group (P < .05). In the PDTC group testicular weights and Johnsen scores were similar with the control group (P > .05). Immunohistochemically there was marked staining in the iNOS and p65 expressions in the torsion group compared with group 2 and 3. In rats administered PDTC, iNOS and p65 expressions were significantly reduced compared with the torsion group. There were no significant differences between the histological and immunohistochemical results of groups 2 and 3. CONCLUSION: This data suggests that IR induces iNOS expressions through the activation of NFKB, p65. The NFKB pathway plays major role in testicular reperfusion injuries. It is possible to prevent reperfusion injuries using selective the NFKB inhibitor. .
