The predictive impact of hematological inflammatory markers in detecting prostate cancer in patients with PI-RADS 3 lesions on multiparametric magnetic resonance imaging.

BACKGROUND: The diagnostic accuracy of suspicious lesions that are classified as PI-RADS 3 in multiparametric prostate magnetic-resonance imaging (mpMRI) is controversial. This study aims to assess the predictive capacity of hematological inflammatory markers such as neutrophil-lymphocyte ratio (NLR), pan-immune-inflammation value (PIV), and systemic immune-response index (SIRI) in detecting prostate cancer in PI-RADS 3 lesions. METHODS: 276 patients who underwent mpMRI and subsequent prostate biopsy after PI-RADS 3 lesion detection were included in the study. According to the biopsy results, the patients were distributed to two groups as prostate cancer (PCa) and no cancer (non-PCa). Data concerning age, PSA, prostate volume, PSA density, PI-RADS 3 lesion size, prostate biopsy results, monocyte counts (109/L), lymphocyte counts (109/L), platelet counts (109/L), neutrophils count (109/L) were recorded from the complete blood count. From these data; PIV value is obtained by monocyte × neutrophil × platelet/lymphocyte, NLR by neutrophil/lymphocyte, and SIRI by monocyte number × NLR. RESULTS: Significant variations in neutrophil, lymphocyte, and monocyte levels between PCa and non-PCa patient groups were detected (p = 0.009, p = 0.001, p = 0.005 respectively, p < 0.05). NLR, PIV, and SIRI exhibited significant differences, with higher values in PCa patients (p = 0.004, p = 0.001, p < 0.001 respectively, p < 0.05). The area under curve of SIRI was 0.729, with a cut-off value of 1.20 and with a sensitivity 57.70%, and a specificity of 68.70%. CONCLUSION: SIRI outperformed NLR and PIV in detecting PCa in PI-RADS 3 lesions, showcasing its potential as a valuable biomarker. Implementation of this parameter to possible future nomograms has the potential to individualize and risk-stratify the patients in prostate biopsy decision.

Evaluation of four pre-operative models for prediction of biochemical recurrence after radical prostatectomy in localised prostate cancer.

BACKGROUND: Biochemical recurrence (BCR) can be seen in the early or late period after radical prostatectomy (RP). Various models have been developed to predict BCR. OBJECTIVE: In our study, we evaluated the accuracy of four pre-operative models (GP score, PRIX, D'Amico risk classification, CAPRA) in predicting BCR after RP in Turkish patients. METHODS: Age, preoperative total prostate-specific antigen (PSA) values, clinical stages, total number of cores taken in biopsy, number of positive cores, preoperative biopsy Gleason score (GS), follow-up time and presence of BCR after RP were recorded. BCR was defined as a total PSA value >0.2 ng/dL twice consecutively after RP. Classifications or scoring was performed according to pre-operative models. The 1-, 3- and 5-year BCR-free rates of the patients were determined for each model. Also, the accuracy of four predictive models for predicting 1-, 3- and 5-year BCR was evaluated. RESULTS: For all pre-operative models there was a statistically significant difference between risk groups in BCR-free rates at 1-, 3- and 5-year after RP (P < .001). The Harrell's concordance index for 1-year BCR predictions was 0.802, 0.831, 0.773 and 0.745 for the GP score, PRIX, CAPRA and D'Amico, respectively. For 3-year BCR predictions, it was 0.798, 0.791, 0.723 and 0.714 for the GP score, PRIX, CAPRA and D'Amico and respectively. Finally, The Harrell's concordance index for 5-year BCR predictions was 0.778, 0.771, 0.702 and 0.693 for the GP score, PRIX, CAPRA and D'Amico, respectively. CONCLUSION: In the prediction of BCR, the accuracy of GP scoring and PRIX seems slightly higher than CAPRA and D'Amico risk classification. Surely our results should be supported by head to head comparisons within other larger cohorts.

How reliable are imaging techniques in aging males with bladder cancer?

INTRODUCTION: The aim of this study was to evaluate consistency between clinical lymph node positivity and pathological lymph node positivity in patients undergoing open radical cystectomy and pelvic lymph node dissection due to bladder cancer. MATERIAL AND METHOD: A total of 135 patients who had open radical cystectomy, extended lymph node dissection, and clear preoperative contrast-enhanced abdominopelvic computed tomography (CT) or magnetic resonance imaging (MRI) images were included in the study. Positive clinical lymph nodes and positive pathological lymph nodeswere recorded. The largest positive clinical and pathological lymph nodeswere recorded. In terms of clinical lymph node involvement, compatibility between radiological findings and pathological results was evaluated. RESULTS: In the CT group, the sensitivity was 25.81%, specificity was 95.45%, positive predictive value (PPV) was 66.67%, negative predictive value (NPV) was 78.50%, and accuracy was 77.31%. In the MRI group, the sensitivity was 50.00%, specificity was 100%, PPV was 100%, NPV was 76.92%, and accuracy was 81.25%. For consistency between pathological lymph nodes and clinical lymph nodes according to the imaging type, there was no statistically significant difference in the sensitivity, specificity, NPV, and accuracy rates between the imaging techniques (p > 0.05). However, the PPV was significantly higher in the MRI group than the CT group (100% vs.66.67%, respectively; p = 0.014). CONCLUSION: Positive lymph nodes play a critical role in the prognosis of patients with bladder cancer and the sensitivity of contrast-enhanced abdominopelvic CT and MRI used routinely in clinical practice is low in lymph node detection. MRI seems more reliable than CT in lymph node detection.

Effect of artificial urinary sphincter implantation on erectile function and sexual satisfaction.

Artificial urinary sphincter (AUS) implantation is the gold standard treatment in total stress urinary incontinence (SIU). Our aim is to evaluate the effect of AUS implantation on erectile function and sexual satisfaction (SS). Fourteen patients aged 58-73 years (mean: 66.92 ± 4.51 years) who underwent AUS implantation by a perineal approach between May 2015 and April 2018 were included in our study. Patients with neurogenic disease or very low or no erectile function and those who underwent non-nerve-sparing radical prostatectomy were excluded. Erectile function and intercourse satisfaction were evaluated pre-operatively and post-operatively at 6-month follow-up using international index of erectile function (IIEF) questionnaires. After AUS implantation; eight patients were totally dry, four achieved social continence (less than one pad/day), and two still had SUI (two or more pads/day). Mean pre- and post-operative IIEF values of the patients were 16.14 ± 3.18 and 17.42 ± 4.43 respectively. Mean pre- and post-operative SS values were 8.57 ± 1.78 and 8.71 ± 2.19 respectively. There was no statistically significant difference between pre- and post-operative IIEF-5 and intercourse satisfaction scores (p > 0.05). Although we did not see a significant effect of AUS implantation in our study, in SIU patients, coital incontinence or unpleasant odour during intercourse can lead to sexual avoidance and reduced SS, and AUS implantation may improve SS.

The effect of urethroplasty surgery on erectile and orgasmic functions: a prospective study.

OBJECTIVES: To examine the effects of urethroplasty surgery on sexual functions by taking into account age, location of stenosis, length of stenosis and surgical technique parameters. MATERIALS AND METHODS: The prospective study was conducted between January 2015 and August 2017 with 60 cases. Patients were categorized according to age groups (19-65 / 65-75 years), surgery technique and stricture localization and length. Before the urethroplasty operation and postoperative 6th month follow-up, the international index of erectile function (IIEF) form (15 questions), was filled, the relevant domains of sexual function; erectile function (Q1,2,3,4,5,15), orgasmic function (Q9,10) and overall satisfaction (Q13,14) were assessed. RESULTS: The mean age of the cases is 54 ± 13. However, preoperative IIEF, sexual satisfaction and orgasmic function averages of patients with a stenosis segment length of 1-3 cm was found to be significantly higher than that of patients with a stenosis segment length of 4-7 cm. Between stenosis segment length groups, there was no statistical difference in terms of preoperative and postoperative sexual functions. And also, there was no statistically significant change in patients' preoperative and postoperative sexual function scores in terms of localization of stricture and surgery techniques. However, there were statistically significant change in the postoperative IIEF and sexual satisfaction averages according to preoperative averages. CONCLUSION: Our study suggests that urethroplasty surgery itself does not significantly affect erectile function, orgasmic function, and general sexual satisfaction regardless of the type of surgery, localization and length of stenosis. Besides, there was a significant decrease in erectile function in senior adults.

Management and outcomes of urethral stricture: single centre experience over 13 years.

AIM: To present a comprehensive summary of the diagnosis, treatment and follow-up process of patients who underwent open urethroplasty in our tertiary referral center for the treatment of urethral stricture in the last 13 years. MATERIALS AND METHODS: Two hundred and forty-five (245) patients who underwent open urethroplasty between January 2008 and June 2021 were retrospectively analysed. Detailed history, physical examination, uroflowmetry, retrograde urethrography and/or voiding cystourethrography and/or urethroscopy were used throughout the preoperative diagnosis process. While evaluating the postoperative patency rates, the absence of preoperative voiding symptoms after the operation and Qmax 15 ml/sec and above were taken into account. RESULTS: Mean stricture length was 3.8 +/- 1.4 cm. Transurethral endoscopic interventions in 79 patients (32.2%), catheterisation in 55 patients (22.4%), trauma in 54 patients (22%), infection in 15 patients (6.2%), and idiopathology in 42 patients (17.2%) were the causes for the stricture. Buccal mucosal graft was used in 125 patients (51%), penile skin flap in 32 patients (13%), end-to-end anastomosis in 83 patients (33.8%) and Heineke-Mikulicz technique in 5 patients (2%). Mean follow-up period was 67.1 +/- 28.9 months. Success rates of patients were 84% (105) in buccal mucosal graft, 78.1% (25) in penile skin flap, 86.7% (72) with end-to-end anastomosis and 80% (4) with Heineke-Mikulicz technique. CONCLUSION: Among treatment options for urethral stricture, urethroplasty techniques is the most successful treatment. Consideration of the factors leading to the formation of the stricture, with the intraoperative findings and surgical experience will maximize the benefit the patient receives.

Predictive value of systemic immune-inflammation index in recurrent urethral strictures.

PURPOSE: To investigate the predictive value of systemic immune-inflammation index (SII) in recurrence of urethral stricture in patients undergoing internal urethrotomy. METHODS: In this two-center, retrospective study, 703 patients who had internal urethrotomy for urethral stricture were included. Demographic, clinical, and laboratory characteristics and operative data were obtained. Two groups were formed from the patients as non-recurrent urethral stricture (n = 490) and recurrent urethral stricture (n = 213). RESULTS: There was no significant difference in the mean age between the patients with and without recurrence. There was a significant difference in the mean SII values and albumin levels between the recurrence and non-recurrence groups (p = 0.001 and p = 0.006, respectively). Using a cut-off value of 252 for the SII; the sensitivity was 59.62%, the specificity was 70.41%, the positive predictive value was 46.69%, the negative predictive value was 80.05% and the accuracy was 67.14%, respectively. Statistically significant correlation was found between the presence of recurrence and the established cut-off value of the SII (p = 0.001 and p < 0.01, respectively). The risk of recurrence was stated that 3.514 times higher in patients with a SII value of ⩾252. CONCLUSION: Using the SII the inflammatory state of the urethral tissue can be evaluated. Thus the risk of recurrence after internal urethrotomy operation can be predicted. Open urethroplasty technique instead of DVIU in patients with high SII values may increase the surgical success rates.

Is testosterone deficiency a predictive factor for recurrence of urethral stricture?

BACKGROUND: Testosterone plays a vital role in maintaining tissue homeostasis, and testosterone deficiency may potentially influence the likelihood of urethral stricture recurrence. OBJECTIVES: To evaluate the prognostic value of testosterone levels in the recurrence after direct visual internal urethrotomy in primary short segment bulbar urethral strictures and its clinical reflections. MATERIALS AND METHODS: A total of 723 patients who underwent direct vision internal urethrotomy between January 2000 and October 2022 were retrospectively analyzed. After implying exclusion criteria, 116 patients with available data were enrolled. Patients were divided into two groups as recurrence and no recurrence. Age, stricture length, etiology, time of recurrence, diagnosis of previous diabetes mellitus, hypertension, smoking, body mass index, and total testosterone levels were recorded. Free testosterone and bioavailable testosterone values were calculated using total testosterone, albumin, and sex hormone binding globulin values. Hypogonadism was considered as a total testosterone level less than 300 ng/dL. Demographic characteristics and total testosterone, free testosterone, and bioavailable testosterone levels were compared between the two groups for statistical significance. The recurrence rates of patients with and without hypogonadism were compared. RESULTS: Recurrence was observed in 41.4% of the cases (n = 48). There was no statistically significant difference between the groups in terms of age, body mass index values, diabetes mellitus, hypertension, smoking status, presence of hypogonadism, and etiology (p = 0.745, 0.863, 0.621, 0.622, 0.168, 0.051, and 0.232). In terms of total testosterone levels and bioavailable testosterone levels, the recurrence group had significantly lower values (p = 0.018 and 0.04). There was no significant difference between the two groups in terms of stricture length (p = 0.071). Sixteen of 28 patients with hypogonadism had recurrence, whereas 32 of 88 patients without hypogonadism had recurrence (p = 0.051). DISCUSSION: Testosterone levels have potential to predict recurrence in primary short-segment bulbar urethral strictures. This study represents the inaugural analysis of the impact of testosterone deficiency on recurrence within the cohort of patients with primary short-segment bulbar urethral strictures. CONCLUSION: Testosterone levels and ratios may serve as predictive factors for identifying recurrent cases in primary short-segment bulbar strictures. For patients at a higher risk of recurrence, urethroplasty may be considered as an initial treatment option, even in cases of primary and short-segment strictures.

The fear of COVID-19 scale: Its structure and measurement invariance across 48 countries.

Coronavirus disease (COVID-19) has been a source of fear around the world. We asked whether the measurement of this fear is trustworthy and comparable across countries. In particular, we explored the measurement invariance and cross-cultural replicability of the widely used Fear of COVID-19 scale (FCV-19S), testing community samples from 48 countries (N = 14,558). The findings indicate that the FCV-19S has a somewhat problematic structure, yet the one-factor solution is replicable across cultural contexts and could be used in studies that compare people who vary on gender and educational level. The validity of the scale is supported by a consistent pattern of positive correlations with perceived stress and general anxiety. However, given the unclear structure of the FCV-19S, we recommend using latent factor scores, instead of raw scores, especially in cross-cultural comparisons.

Effects of platelet-rich plasma on spermatogenesis and hormone production in an experimental testicular torsion model.

BACKGROUND: Platelet-rich plasma is a biological instrument rich in growth factors and cytokines. OBJECTIVES: The aim of this study was to investigate the effect of platelet-rich plasma on spermatogenesis and hormone production in an experimental testicular torsion model. MATERIALS AND METHODS: The rats were randomly divided into three groups, including six rats in each group as follows: the first group as the sham group; the second group as the ischemia/reperfusion + Saline group and the third group as the ischemia/reperfusion + platelet-rich plasma group. The left testicles of the ischemia/reperfusion + Saline and ischemia/reperfusion + platelet-rich plasma group were kept in four-hour torsion. Then, the left testicles of ischemia/reperfusion + Saline and ischemia/reperfusion + platelet-rich plasma groups were detorsioned, and intra-testicular 1 cc saline (ischemia/reperfusion + Saline) and 1 cc platelet-rich plasma (ischemia/reperfusion + platelet-rich plasma) were injected. At one month, blood samples were taken from all groups for hormonal evaluation and left orchiectomy was performed. RESULTS: The mean follicle-stimulating hormone level of ischemia/reperfusion + Saline group was significantly higher than ischemia/reperfusion + platelet-rich plasma group (7.78 ± 0.23 vs 6.18 ± 0.28 nmol/l, respectively, P = .004). The mean LH level of ischemia/reperfusion + platelet-rich plasma group was significantly lower than ischemia/reperfusion + Saline group (3.63 ± 0.28 vs 5.68 ± 0.21 nmol/l, respectively, P = .004). The mean total testosterone level of ischemia/reperfusion + platelet-rich plasma group was significantly higher than ischemia/reperfusion + Saline group (8.05 ± 0.24 vs 5.78 ± 0.23 nmol/l, respectively, P = .004). The mean Johnsen scores of ischemia/reperfusion + platelet-rich plasma group were significantly higher than ischemia/reperfusion + Saline group (5.85 ± 0.58 vs 3.93 ± 0.65, respectively, P = .004). The mean Johnsen score of the sham group was significantly higher than ischemia/reperfusion + platelet-rich plasma and ischemia/reperfusion + Saline groups (P = .003 and P = .003, respectively). DISCUSSION AND CONCLUSION: The platelet-rich plasma has beneficial effects on spermatogenesis and reproductive hormone production in testicular torsion. It is easily accessible and applicable. In the future, intra-testicular platelet-rich plasma injection may be used in testicular torsion after detorsion. However, further experimental and large-scale prospective clinical studies are needed to establish a definitive conclusion on this topic.

Renoprotective effect of platelet-rich plasma in obstructive uropathy.

PURPOSE: To investigate the effect of platelet-rich plasma (PRP) in reducing renal injury in ureteral obstruction. METHODS: Twenty-four Wistar Albino rats were randomized and divided into four groups as the donor (n = 6), sham (n = 6), saline (n = 6), and PRP (n = 6). Blood was obtained from the donor group by cardiac puncture and PRP was prepared. 2 cc blood was sampled from other groups to measure blood-urea nitrogen and creatinine levels. Baseline renal scintigraphy was performed. An abdominal midline incision was made and the left ureter was exposed in the sham group. Saline infusion was given to the kidneys of the saline group after left ureteral obstruction, while PRP was given to the PRP group. On postoperative Day 7, control biochemical and scintigraphic evaluations were performed and left nephrectomies were done. Left kidneys were evaluated histopathologically. RESULTS: DMSA measurements in the sham group were found to be significantly higher than the saline and PRP groups (p = 0.001 and p = 0.024, respectively). There were no significant differences between the saline and PRP groups (p = 0.525 and p > 0.05, respectively). Histopathologically, no significant difference was observed between the saline and PRP groups (p = 0.320), while the scores of the sham group were significantly higher than the saline and PRP groups (p = 0.02 and p = 0.001, respectively). CONCLUSION: Our study results suggest that PRP may be effective in preventing ureteral obstruction-induced renal injury.

Structure of Dark Triad Dirty Dozen Across Eight World Regions.

The Dark Triad (i.e., narcissism, psychopathy, Machiavellianism) has garnered intense attention over the past 15 years. We examined the structure of these traits' measure-the Dark Triad Dirty Dozen (DTDD)-in a sample of 11,488 participants from three W.E.I.R.D. (i.e., North America, Oceania, Western Europe) and five non-W.E.I.R.D. (i.e., Asia, Middle East, non-Western Europe, South America, sub-Saharan Africa) world regions. The results confirmed the measurement invariance of the DTDD across participants' sex in all world regions, with men scoring higher than women on all traits (except for psychopathy in Asia, where the difference was not significant). We found evidence for metric (and partial scalar) measurement invariance within and between W.E.I.R.D. and non-W.E.I.R.D. world regions. The results generally support the structure of the DTDD.

Fournier's gangrene: Review of 36 cases.

BACKGROUND: Fournier's gangrene (FG) is a very rare disease in daily urological practice. Despite medical improvements, mortality in FG is still high. Early diagnosis is very important to reduce additional instrumentations and mortality. In this study, we aimed to present the characteristics of the patients with Fournier's gangrene followed in two centers during ten years period. METHODS: The medical records of patients with FG were reviewed retrospectively. The patient characteristics, causative pathogens, laboratory findings and treatment modalities were evaluated. RESULTS: A total of 36 FG cases admitted between January 2008 and February 2018 were included in this study, consisting of 35 male patients, and one female patient with a mean age of 59.27±12.91 years. The mean duration of hospital stay was 19±10.44 days. The most common predisposing factor was diabetes mellitus, which was found in 28 patients. Malignancy was detected in three patients; prostate cancer in two patients and chronic lymphoblastic leukemia in one patient. Two patients had liver cirrhosis, and one patient had Behcet's disease and psoriasis. The microbiological agent was isolated from a wound culture in nine patients. After urgent surgical debridement, daily dressing with nitrofurazone (Furacin) was done. Additional debridement was conducted when necessary. Orchiectomy was performed in 10 patients; two of them underwent bilateral orchiectomy. One patient died because of sepsis on the seventh day of hospital admission. CONCLUSION: FG is a life-threatening urological emergency with a high mortality rate. Treatment with broad-spectrum antibiotics and urgent surgery is pivotal for the prevention of mortality.

Renal angiomyolipoma.

INTRODUCTION: Angiomyolipoma is one of the most common benign solid renal tumors. We investigated the characteristics of renal angiomyolipomas and the clinical outcomes of patients in the last thirteen years. METHODS: The medical records of the patients who underwent nephrectomy were reviewed retrospectively from July 2005 to May 2018. The laboratory data, radiology, and pathology reports were recorded. Patients diagnosed with angiomyolipoma were included in the study. RESULTS: A total of 28 patients were included in the study, eight of them male. The mean age of the patients was 55.89+14.49 years. The patients were treated with open and laparoscopic techniques. Partial nephrectomy was performed in 12 patients(42.85%). After pathological examination, 23 patients were diagnosed as fat rich, four patients as fat poor, and one as epithelioid angiomyolipoma. There were no recurrences in the follow-up 91.21+48.31 months. CONCLUSION: Angiomyolipoma is a rare renal tumor in daily urology practice. Clinicians must be aware of its complications and manage patients well.

Characteristics of the urethroplasty and our approach-Experience in patients with urethral stricture.

OBJECTIVE: Urethral stricture is a common pathology with different etiologic factors in different age groups and societies. In our research, patients who underwent urethroplasty because of urethral stricture were evaluated in terms of etiology, localization, surgical technique and demographic characteristics. MATERIAL AND METHODS: One hundred and sixty-three patients with a mean age of 53.43±16.5 years, operated between January 2008 and May 2016 because of urethral stricture were retrospectively included in the study. Diagnosis of the urethral stricture was established based on the complaints of the patient, results of urinalysis, urine culture, uroflowmetry, retrograde urethrography and/or voiding urethrography, and urethroscopy in case of need. Postoperative success for the patients was determined based on urinary flow rate and maximum flow rate of over 15 mL/sec were evaluated as success. RESULTS: Etiologic factors for urethral stricture included trauma in 40 (24.5%), urethral catheterization in 45 (27.6%), endoscopic procedure in 59 (36.2%), infection in 10 (6.2%), idiopathic etiologies in 9 (5.5%) out of 163 patients. Mean length of the stricture was 3.6±1.7 cm. While the indicated number of patients had buccal mucosa graft (n=73, 44.7%), penile skin flap (n=21, 12.8%), Heineke-Mikulicz repair (n=5, 3.0%), and end-to-end anastomosis (n=64, 39.1%). Mean follow-up period was 43.2±33.7 months. Buccal mucosa graft was applied as ventral (n=32, 43.8%), dorsal (n=22, 30.2%), and dorsolateral (n=14, 19.2%) onlay, and transventrally dorsal inlay (n=5, 6.8%) grafts. Average success rates were 83.5% (n=61/73) in buccal mucosa, 76.2% (n=16/21) in penile skin grafts; 85.9% (n=55/64) in end-to-end anastomosis and 80.0% (n=4/5) in Heineke-Mikulicz repair. CONCLUSION: Our assumption is that urethroplasty procedures have satisfactory long-term results, regardless of the location and size of the stenosis. According to our clinical experience, deciding on the most appropriate surgical technique by assessing each patient individually in experienced centers will increase success rates.

The effect of metabolic syndrome on prostate cancer final pathology.

AIM OF STUDY: Metabolic syndrome (MetS) is an abnormality that increases the risk of cardiovascular disease and diabetes. In the recent years, studies showed that MetS is associated with increased risk of incidence, aggressiveness, and mortality of prostate cancer (PCa). We examined the influence of MetS at final pathology in Turkish patients with PCa. MATERIALS AND METHODS: MetS was defined according to the American Heart Association, National Heart, Lung, Blood Institute, and International Diabetes Federation and requires any three of five components. The patients without and with MetS were in Group 1 and 2, respectively. Data were compared with independent sample t-test and Chi-squared test. RESULTS: There were 117 patients in the study. The patients' age was between 51 and 77 years with a median of 64.87 ± 5.65 and 62.29 ± 5.57, and prostate-specific antigen (PSA) level of the patients was 8.19 ± 5.35 and 8.68 ± 2.22 ng/ml in Group 1 and 2. Of these patients; Group 1 and 2 had 86 and 31 patients. High-grade PCa (Gleason >7) and advanced PCa (T3, T4) at final pathology were reported in 44.18-18.60% and 38.70-32.25% in Group 1 and 2. CONCLUSION: The patients with MetS are diagnosed significantly younger and had higher PSA levels than the other patients. Advanced disease of PCa is seen much more in patients with MetS.

Is neutrophil to lymphocyte ratio a predictive factor for recurrence of urethral stricture?

INTRODUCTION: Due to spongiofibrosis and inflammatory processes underlying the pathogenesis of urethral stricture, it is possible that the neutrophil-lymphocyte ratio (NLR) may give essential information about the course of the disease and recurrence possibilities. Our study aims to evaluate the correlation between NLR and recurrence rates. METHODS: A total of 512 patients who underwent direct visual internal urethrotomy (DVIU) due to urethral stricture in our clinic between February 2010 and January 2018 were evaluated retrospectively. RESULTS: The median follow up for non-recurrent and recurrent groups after DVIU was 30 and 36 months, respectively. During the follow-up, 280 (54.7%) of the patients had recurrences, and 232 (45,3%) had no recurrences. The mean time for recurrence after DVIU was 6,5±1,4 months, with a range of 1-36 months. The mean NLR in the non-recurrence group was 2,02±0,87, with a median of 1.9, and 3,66±2,30, with a median of 3 in the recurrence group. A highly significant statistical difference was observed between two groups in terms of neutrophil count and NLR (p: 0.000 - both). The area under curve value for NLR was 0.767, with a standard error of 0.021 (95% CI 0.727-0.808). The cut-off value of NLR was determined as 2.25, with a 70% sensitivity and 67,7% specificity. CONCLUSION: By using NLR, the inflammatory features of the urethral tissue can be predicted, and possible recurrences after surgery can be estimated. Consequently, open urethroplasty techniques can be used in cases with a significant NLR value instead of the recurrent endoscopic procedure.

HIV Negative Penile Kaposi's Sarcoma in Circumcised Men.

Kaposi's sarcoma (KS) is an inflammatory vascular tumor, which can be seen at multiple areas in the body, especially at skin and extremities, mostly in immunosuppressed patients like organ receivers and AIDS patients. It can also be seen in human immune deficiency virus (HIV) negative, heterosexual, circumcised and non-immunosuppressed patients; and the disease course may be very variable. Herein, we present three patients who were referred to our clinic in the last five years and had a rather different course of disease; they were heterosexual, circumcised, non-immunosuppressed, and HIV negative. KS should be kept in mind in nonspecific penile lesions even if the patient is HIV negative. KS has a high recurrence rate even with any kind of treatment. More studies are needed for determining true recurrence rates, treatment plans and any underlying diseases.

Diagnosis and Treatment of Paratesticular Adenomatoid Tumors.

Paratesticular adenomatoid tumor (PAT) is the most common paratesticular tumor. It is still a concern for today's urologists because it cannot be distinguished from malignant testicular tumors by clinical symptoms, routine examination and imaging methods. Because of the predominant benign nature of paratesticular masses, testicular preservative treatments get to the foreground. However, the fact that virtually all of the solid scrotal masses are malignant and are treated with radicel ingainel orchiectomy (RIO) remains a cause of concern. In this study, we discuss the diagnosis and treatment of 12 paratesticular adenomatoid tumors treated between 2012 and 2017 in two centres. We suggest that a frozen section should be done with the help of an experienced pathologist; and a meticulous microscopic evaluation should be the gold standard in case of a benign tumor suspicion.
