A rare complication of inguinal hernia repair: Total testicular ischemia and necrosis
Testicular ischemia and necrosis are quite rare complications following inguinal hernia repair. There is still no consensus on the mechanism of infarction and necrosis in the literature. We present a case with total testicular ischemia and necrosis in the early period following the inguinal hernia repair with prolene mesh, ending up with orchiectomy
Impact of Reducing Irritative Symptoms in Non-Muscle Invasive Bladder Cancer During BCG Instillation: A Pilot Study
INTRODUCTION: We evaluated use of anticholinergics, mirabegron, and combination of anticholinergics with mirabegron during Bacillus Calmette-Guérin (BCG) instillation for reducing irritative symptoms in patients with non-muscle invasive bladder cancer (NMIBC). METHODS: Prospectively recorded data of NMIBC patients receiving BCG were retrospectively evaluated between August 2015 and April 2019. Patients with low-grade T1 solitary papillary lesions <4 cm were included in the study. Validated questionnaires (OAB-V8) for irritative symptoms adapted to Turkish language, and QoL index forms were filled out by the study participants. OAB-V8 scores of ≥8 were considered as an indication to start medical treatment for irritative symptoms. Groups were formed according to daily used anticholinergic drugs and combinations as follows: Group 1, tolterodine; Group 2, solifenacin 5mg; Group 3, mirabegron, and Group 4, mirabegron with solifenacin 5 mg. RESULTS: Mean follow- up period was 20.4+-6.8 months. There were 132 patients [110 men (83%) and 22 (17%) women] with irritative symptoms and NMIBC. Mean age of the study population was 59.7+-12.4 years. The OAB-V8 scores and QoL indexes significantly improved with all drugs. However, in subgroup analyses, Group 4 provided the most dramatic improvement in OAB-V8 and QoL index scores (P=0.02 for both). The longest in time to micturition was recorded in Group 4 (P=0.04). Tumour recurrence was similar for groups 12 months after BCG instillation (P=0.9), however the least recurrence was observed in Group 4. DISCUSSION AND CONCLUSION: Combination of solifecacin and mirabegron can reduce irritative symptoms, improve QoL, and prolong time to micturition, during BCG instillation in selected NMIBC patients. This combination may also decrease recurrence rates in this patient population

Preliminary Assessment of Neck Circumference in Benign Prostatic Hyperplasia in Patients with Metabolic Syndrome
Objectives To investigate the impact of neck circumference (NC) in the treatment of bening prostatic hyperplasia (BPH) patients with metabolic syndrome (MtS). Additionally, we determined dose response to alpha-blockers and cut-off values for NC and waist circumference (WC), in these patients. Materials and Methods Non-randomized, open-labelled, and multi-centre study was conducted between March 2014 and September 2015. The BPH patients were enrolled and were divided into 2 groups: with MtS (Group 1; n=94) and without MtS (Group 2; n=103). Demographic data, anthropometric measurements, blood analyses, uroflowmetric parameters, post voiding residual urine (PVR), prostate volume, quality of life (QoL) index, NC and WC were recorded. Both groups were administered oral alpha-blockers and response to treatment was evaluated. Receiver-operating characteristic (ROC) curves were obtained and significant p was p<0.05 . Results In total, 197 patients were enrolled with mean age of 60.5±8.1 years. Mean NC and WC were higher in MtS patients (p<0.001). Uroflowmetry parameters and QoL indexes were comparable between groups before treatment. International prostate symptom score, uroflowmetry parameters, and QoL significant improved in Group 2 than Group 1, at 1 st and 6 th months of treatment with alpha-blockers. Success rate of treatment was significant higher in Group 2 than Group 1 (p<0.001). Cut-off values were 42.5cm and 113.5cm for NC and WC respectively, for response to alpha-blockers in BPH patients with MtS. Conclusions MtS can be related with BPH and can negatively affect the response to alpha-blocker treatment. NC can be used for predicting response to alpha-blocker treatment in BPH patients with MtS.PubMedWoSScopu
The impact of extracorporeal shock wave therapy for the treatment of young patients with vasculogenic mild erectile dysfunction: A prospective randomized single-blind, sham controlled study
Background Low-intensity extracorporeal shock wave therapy (ESWT) for the treatment of vasculogenic erectile dysfunction (ED) has emerged as a promising method directly targeting the underlying pathophysiology of the disease. Objectives To compare outcomes in ED patients after ESWT and placebo treatment. Materials and methods Prospective randomized placebo-controlled single-blinded trial on 66 patients with mild ED. The study comprised a 4-week washout phase, a 4-week treatment phase, and a 48-week follow-up. Inclusion criteria included age between 18 and 75 years and diagnosis of mild ED (IIEF-EF score = 17-25) being made at least six months prior to study inclusion and being confirmed by Penile Doppler ultrasonography (US) at baseline examination. Efficacy endpoints were changes from baseline in patient-reported outcomes of erectile function (International Index of Erectile Function domain scores [IIEF-EF]), as well as erection hardness and duration (Sexual Encounter Profile diary [SEP] and Global Assessment Questions [GAQ]). Safety was assessed throughout the study. Results A total of 66 enrolled patients were allocated to ESWT (n = 44) or placebo (n = 22). Mean age of ESWT and placebo group was 42.32 +/- 9.88 and 39.86 +/- 11.64 (p = 0.374), respectively. Mean baseline IIEF-EF scores of ESWT group and placebo were 20.32 +/- 2.32 and 19.68 +/- 1.55 respectively (p = 0.34). At 3-months follow-up, mean IIEF-EF scores were significantly higher in ESWT patients than in placebo patients (23.10 +/- 2.82 vs. 20.95 +/- 2.19, p = 0.003), and IIEF-EF scores of ESWT patients remained high during the 6 months (22.67 +/- 3.35 vs. 19.82 +/- 1.56) follow-up. The percentage of patients reporting both successful penetration (SEP2) and intercourse (SEP3) in more than 50% of attempts was significantly higher in ESWT-treated patients than in placebo patients (p = 0.001). A minimal clinically important difference between the IIEF = EF baseline and 3-months follow-up was found in 74% of ESWT and 36% of placebo. No serious adverse events were reported. Discussion and Conclusion ESWT significantly improved the erectile function of relatively young patients with vasculogenic mild ED when compared to placebo and the beneficial effect of this treatment up to 6 months. These findings suggest that ESWT could be a useful treatment option in vasculogenic ED
Preoperative neutrophil-to-lymphocyte ratio as a new prognostic predictor after microsurgical subinguinal varicocelectomy
Various studies have been reported to predict the success of varicocelectomy. Neutrophil-lymphocyte ratio (NLR) is a frequently used indicator of systemic inflammation. We aimed to evaluate the effect of inflammation on the success of varicocelectomy using the NLR. The data of 86 patients who underwent varicocelectomy for infertility were evaluated retrospectively. Pre-operative demographic characteristics of patients, laboratory results such as haemogram, and semen analysis and clinical data were recorded. The semen analysis with the highest total motile sperm count was accepted as pre-operative value. Control was performed with semen analysis at post-operative 6th month. As described in previous studies, in our study, more than 50% increase in total motile sperm count in post-operative semen analysis was defined as a significant improvement. However, at least a 100% increase was required for patients with a total motile sperm count <5 million in the definition of recovery. Patients were divided into two groups as those with improvement in the semen parameters (Group 1) and those without (Group 2). NLR was statistically significantly higher in Group 2 compared with Group 1. The area under the curve (AUC) in the ROC curve for NLR was 0.89. According to the Youden index, the best cut-off value of NLR for varicocelectomy success was 1.98 (sensitivity: 94.7%, specificity: 75.9%, p < 0.001). Logistic regression analysis showed that NLR (odds ratio: 3.6, 95% confidence interval: 1.69-8.38, p < 0.001) is independent predictor factors in predicting the success of varicocelectomy. The results of this study show that systemic inflammation adversely affects the likelihood of improvement in sperm parameters by varicocelectomy. Additionally, NLR has been shown to be an independent factor in the prediction of varicocelectomy success

sChronic administration of sildenafil improves erectile function in a rat model of chronic renal failure
The relationship between erectile dysfunction (ED) and chronic renal failure (CRF) has been reported in several studies. This study aimed to investigate whether the chronic use of sildenafil could enhance the erectile capacity in CRF-induced rats. In addition, we assessed the effect of that treatment on certain molecules, which have been suggested to play crucial roles in erectile physiology and CRF-related ED as well. Three groups of animals were utilized: (1) age-matched control rats, (2) CRF-induced rats, (3) CRF-induced rats treated with chronic administration of sildenafil (5 mg kg−1 p.o. for 6 weeks [treatment started after 6 weeks of CRF induction]). At 3 months, all animals underwent cavernosal nerve stimulation (CNS) to assess erectile function. Penile tissue advanced glycation end products (AGE′s)/5-hydroxymethyl-2-furaldehyde, malondialdehyde (MDA), cGMP (ELISA), inducible nitric oxide synthase (iNOS) and neuronal NOS (nNOS) (Western blot) analyses were performed in all rat groups. CRF-induced rats had a significant decrease in erectile function when compared to control rats (P < 0.05). The increase in both intracavernosal pressure (ICP) and area under the curve of CRF-induced rats treated with sildenafil (Group 3) was greater than CRF-induced rats (Group 2). Additionally, sildenafil treatment decreased AGE, MDA and iNOS levels, while it preserved nNOS and cGMP contents in CRF-induced penile tissue. Decreased AGE, MDA, iNOS and increased nNOS, cGMP levels at the sildenafil-treated group increased both ICP and Total ICP to CNS, which led to improve erectile function in CRF-induced rats. The results of the present study revealed the therapeutic effect of chronic sildenafil administration on erectile function in CRF-induced rats
Epithelial-Mesenchymal Transition Markers beta-catenin, Snail, and E-Cadherin do not Predict Disease Free Survival in Prostate Adenocarcinoma: a Prospective Study
Current methods for diagnosis and staging of prostate adenocarcinoma are not sensitive enough to distinguish between patients with indolent disease and those that should receive radical treatment. Epithelial-mesencyhmal transition (EMT) is a well-characterized process involved in tumor invasion and metastasis. The aim of this study is to analyze the expression of beta-catenin, Snail, and E-cadherin in prostate cancer patients with prospective evaluation of their value in predicting disease-free survival (DFS). One-hundred-and-three consecutive prostate carcinoma patients who underwent radical prostatectomy and 35 patients with benign prostate hyperplasia (BPH) were enrolled. Age, initial PSA level, tumor size and clinical stage were documented for adenocarcinoma patients and they were enrolled in active surveillance with serum PSA levels. Recurrence was defined as PSA level of a parts per thousand yen0.2 ng/ml on at least 2 occasions over a 2-month period. Immunohistochemical staining intensity was scored as negative, weakly positive, moderately positive, and strongly positive. For Snail and beta-catenin immunoreaction, the tumors were considered nuclear positive when more than 5 % of the nuclei of tumor cells were positively stained. Patients with prostate cancer had weaker beta-catenin (p < 0.0001), Snail (p = 0.006), and E-cadherin (p = 0.02) staining when compared to BPH patients and the frequency of nuclear positivity for beta-catenin and Snail were higher in adenocarcinoma group (p < 0.0001). Increased expression and nuclear positivity of beta-catenin were associated with advanced stage (p = 0.012 and p = 0.003) and higher tumor volume (p = 0.013 and p = 0.002). Additionally, patients with increased Snail expression had higher Gleason scores and tumor volume at presentation (p = 0.008 and p = 0.004). However, there were no significant DFS differences in adenocarcinoma patients who did and did not have beta-catenin, Snail, and E-cadherin expression as assessed with log-rank test. Expressions of beta-catenin, Snail, and E-cadherin were significantly lower in prostate cancer patients compared to BPH patients and both beta-catenin and Snail had nuclear staining pattern in patients with adenocarcinoma. However, none of these markers predicted DFS in 36-month follow up of our cohort
Laparoscopic Dismembered Pyeloplasty in a Solitary Kidney with Intrarenal Pelvis: Two Challenges in One Case
Laparoscopic pyeloplasty (LP) for ureteropelvic junction obstruction (UPJO) is one of the most appropriate surgical techniques to achieve the optimal goal of minimally invasive surgery. However, urologists hesitate to use the laparoscopic approach in UPJO with solitary kidney or intrarenal pelvis. There are a few published studies on laparoscopic pyeloplasty cases in intrarenal pelvis. However, to the best of our knowledge, the present case is the first in the literature in terms of intrarenal pelvis in a solitary kidney. Generally, YV plasty is the accepted technique instead of dismembered pyeloplasty in UPJO with small or intrarenal pelvis. However, in this report, we showed that dismembered LP can be performed with good results in intrarenal pelvis UPJO, even if it is in the solitary kidney
