RESUMO
PURPOSE: This controlled study assessed whether there was a correlation between serum total testosterone levels and bladder cancer (BCa) in terms of tumor grade and stage as objective measures in adult men. MATERIALS AND METHOD: Our prospectively-designed study included 257 patients who were diagnosed with primary BCa and its surgery between January 2017 and January 2020. Hundred and forty patients who had surgery in the same period with TUR for prostate or endoscopic ureteral stone treatment were included in the study as a control group. All patients in the study and control groups were male. The age range of the patients was between 34 and 90 years old. In order to examine groups, fasting blood glucose, lipid profile, albumin, total testosterone, and vitamin D levels of all patients included in the study. RESULTS: The relationship between tumor aggression and total testosterone level was investigated with a multinomial logistic regression model, where the control group was accepted as a reference, following adjustment for potential confounding variables, including age and serum albumin levels. Testosterone level was not found to be associated with any of the categories that determine tumor aggressiveness (p > 0.05). CONCLUSION: In the present study, there was no correlation between any categories that determine tumor aggressiveness of BCa and total testosterone levels in adult men. It is obvious that our findings should be supported and further investigations are needed.

Diabetes mellitus is associated with increased risk of erectile dysfunction. Penile prosthesis implantation is an efficient therapeutic option for erectile dysfunction, but not without risk, as infection remains a prominent concern. This study investigates diabetes mellitus as a risk factor for penile prosthesis implantation infection and the relationship between haemoglobinA1c levels and infection rates. All diabetic patients with erectile dysfunction who underwent penile prosthesis implantation surgery between January 2012 and November 2019 at Hamad Medical Corporation, Qatar, were included in this retrospective observational study. A total of 599 diabetic patients with erectile dysfunction had penile prosthesis implantation. Mean age was 59.69 ± 31.19. Penile prosthesis implantation infection rate was 0.83% (5/599), while the mean haemoglobinA1c level was 7.58 ± 1.45 mmol/l (range: 4.1-12.6). A comparison between diabetic patients with penile prosthesis implantation infection and those without infection revealed no significant difference in the level of haemoglobinA1c between the two groups with mean haemoglobinA1c in patients with infected implants 7.14 and 7.59 for noninfected (p = 0.491). Limitations include retrospective single-centre design and low-infection rates reducing sample number. Penile prosthesis implantation infection rate in a large series of diabetic patients was low with no significant association between haemoglobinA1c level and penile prosthesis implantation infection observed.

Overactive bladder (OAB) is characterized by the storage symptoms of urgency with or without urgency incontinence. Although there is no clear cause of this idiopathic disease, overall prevalence of OAB symptoms in individuals aged 40 years old is more than 15%. Oxytocin, which is one of the most powerful contracting neuropeptide, was also shown to exhibit high intrinsic contractile activity on detrusor muscle. Oxytocin receptor antagonists that inhibit of bladder activity might offer new insights into the treatment of OAB.

Around 400 million people across the globe will suffer from asthma in the next 10 years. Although most asthmatics use asthma medications regularly, they occasionally visit the emergency department for aggressive treatment amidst family anxiousness. Vitamin D (VD) not only regulates the expression of genes associated with calcium homeostasis, but also the genes associated with cancers, autoimmune diseases, and infection. VD has also non-genomic activities e.g. it is a potentially safe and effective novel strategy for decreasing the asthma episodes and controlling exacerbations. Our review assessed the dose, serum level, duration of administration and outcomes of VD in cases of asthmas. Although a body of research evidences the effectiveness of VD supplementation in asthma, other studies showed the insignificant response of VD to asthma either with low dose or low achieved serum VD levels. Nevertheless, recent reviews suggest that manipulating VD status holds promise for primary prevention and treatment of asthma. Future research on the relationship between VD and asthma should consider utilizing adequate doses of VD preparations for sufficient duration (likely to be >12 months) aiming to achieve appropriate level of serum VD (25-hydroxyvitamin D) concentration (likely to be at least >40 ng/mL).

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the contractile effects of oxytocin (OT) in human detrusor muscle in in vitro conditions. MATERIAL AND METHODS: Human detrusor muscle samples were obtained from seven patients that undergone radical cystectomy. Four female Wistar rats' uterine samples were used as control. Contractile responses were tested of carbachol in organ bath. Cumulative concentration response curves were constructed to OT and then the strips were incubated with atosiban (OT antagonist) and a second concentration response curve to OT were constructed. RESULTS: Carbachol, contracted all human strips for the functionality test whereas OT in any concentrations did not produce significant contraction on all human strips. In only one bladder strip and in a very high concentration slight contraction was recorded. Moreover no contractile response was recorded in any OT concentrations in the presence of atosiban. The rat uterine strips responded to OT in a dose dependent manner. Atosiban, the OT receptor antagonist diminished totally those contractile responses. CONCLUSION: It is been demonstrated here that there is no contractile response to OT in human detrusor muscle. These findings should be supported by further investigations determining the presence of the OT receptor in human detrusor.

BACKGROUND AND OBJECTIVES: Vascular abnormalities are the most common factors in patients with erectile dysfunction (ED). There are limited number of case series investigating the etiology of corporoveno-occlusive dysfunction (CVOD). In this study, we evaluated ED patients with vascular etiologies and their serum biomarkers from a large database. MATERIALS AND METHODS: The current study retrospectively examined the association between serum testosterone levels and basic lab works with Penile Doppler Ultrasonography (PDU) results. We retrieved and reviewed the records of 500 ED patients who had PDU at our institution between January 2012 and November 2018. One-way analysis of variance and Pearson's correlation coefficients were used to compare different parameters between groups (CVOD and penile arterial insufficiency) and between two quantitative variables, respectively. RESULTS: Sixty patients who met the inclusion criteria were enrolled and examined in this study. Patients' mean age was 52.9 ± 11.5 years, and mean serum testosterone level was 15.57 ± 6.49 nmol/L. Thirty-nine (65%) out of 60 patients had abnormal EDV values (>5cm/sec), while eleven (18.3%) had abnormal PSV values (<35cm/sec). Among the patients with abnormal EDV values, we demonstrated that there was a statistically significant negative correlation between testosterone and CVOD (Pearson's; r = -0.283; p = .028). CONCLUSIONS: Our findings supported that low serum testosterone level is a risk factor for CVOD and so for ED. Future studies would benefit from larger sample sizes in order to support or refute our findings.

This study compared the safety and efficacy of the on-demand (OD) use of sertraline (50 mg), sertraline (100 mg) and dapoxetine (30 mg), and the daily use of sertraline (50 mg) in the treatment of patients with premature ejaculation (PE). This prospective randomised study involved 120 lifelong PE patients (intravaginal ejaculatory latency time [IELT]: <1 min; Arabic Index of Premature Ejaculation [AIPE] score: < 30) without secondary causes of PE, identified between March 2018 and May 2020. Patients were divided into 4 groups (30 patients per group) and treated for 8 weeks. Assessments were conducted using the AIPE form as a diagnostic tool. Sertraline (50 mg, daily; 196.7 ± 115.5 s) and sertraline (100 mg, OD; 173.3 ± 97.0 s) had similar IELT and AIPE scores. The latter groups had better results in comparison with sertraline (50 mg, OD; 100.5 ± 54.4 s) and dapoxetine (93.7 ± 53.5 s; p < 0.01). Sertraline (100 mg, OD) had a similar efficacy to that of sertraline (50 mg, daily) and was more effective than sertraline (50 mg, OD) and dapoxetine (30 mg, OD). Sertraline (100 mg, OD) can be considered in the treatment of lifelong PE treatment, having tolerable side effects.

OBJECTIVES: To investigate the characteristics of cases of NIH category I acute prostatitis developed after transrectal prostate biopsy and clarifiy the risk factors and preventive factors. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 3.479 cases of transrectal ultrasound-guided needle biopsies performed with different prophylactic antibiotherapy regimens at two different institutions between January 2011 and February 2016. The patients of Group I have received ciprofloxacin (n=1.523, 500mg twice daily) and the patients of Group II have received ciprofloxacin plus ornidazole (n=1.956, 500mg twice daily) and cleansing enema combination as prophylactic antibiotherapy. The incidence, clinical features and other related microbiological and clinical data, were evaluated. RESULTS: Mean age was 62.38 ± 7.30 (47-75), and the mean prostate volume was 43.17 ± 15.20 (21-100) mL. Of the 3.479 patients, 39 (1.1%) developed acute prostatitis after the prostate biopsy procedure. Of the 39 cases of acute prostatitis, 28/3.042 occurred after the fi rst biopsy and 11/437 occurred after repeat biopsy (p=0.038). In Group I, 22 of 1.523 (1.4%) patients developed acute prostatitis. In Group II, 17 of 1.959 (0.8%) patients developed acute prostatitis. There was no statistical difference between the two groups according to acute prostatitis rates (X2=2.56, P=0.11). Further, hypertension or DM were not related to the development of acute prostatitis (P=0.76, X2=0.096 and P=0.83, X2=0.046, respectively). CONCLUSIONS: Repeat biopsy seems to increase the risk of acute prostatitis, while the use of antibiotics effective for anaerobic pathogens seems not to be essential yet.

BACKGROUND AND OBJECTIVES: Diabetes mellitus is an important risk factor for erectile dysfunction (ED). Penile prosthesis implantation surgery is the final solution for diabetic patients with ED, but infections thereof are still a serious risk factor. While some studies suggest that most infections associated with penile prosthesis implantation are associated to high glycated hemoglobin (HbA1c) levels, other research did support such relationship. MATERIALS AND METHODS: The current study assessed retrospectively, the association between HbA1c level and penile prosthesis surgery infection. We retrieved and reviewed the records of 300 diabetic patients who had penile prosthesis surgery at our Institution (January 2012-November 2016). Patients' mean age was 55.26 ± 10.9 years (31% patients were <50 years of age), and mean HbA1c was 7.60 ± 1.90%. RESULTS: Infection rate among diabetics was 0.67%. Prevalence of prosthesis infection among patients with HbA1c ≤ 9% was 0.9%, compared with 0% among patients with HbA1c > 9%. Prosthesis infection risk did not significantly increase with higher HbA1c levels, with no meaningful difference in the median or mean level of HbA1c in the infected and non-infected diabetic patients. CONCLUSION: Findings do not support the use of HbA1c values among diabetic patients who are candidates for penile prosthesis implantation surgery in order to identify and exclude those who might be prone to increased risk of prosthesis infections. Future studies would benefit from larger sample sizes in order to support or refute our findings.
RESUMO
BACKGROUND: The associations between serum vitamin D (VD), serum testosterone (TT) and metabolic syndrome are complex and with limited published research, particularly on the effects of VD treatment on sexual hormones, erectile function and the metabolic syndrome. OBJECTIVES: This study assessed whether a monthly high dose VD treatment for 12 months in VD deficient middle-aged men was associated with: changes in levels of sexual hormones, improvement of diabetes control and metabolic syndrome components, better erectile function [International Index of Erectile Function (IIEF)-5 questionnaire]; and changes in a prostate marker. MATERIALS AND METHODS: Descriptive research of a prospective study, conducted between October 2014 and September 2015, 102 male patients ≥35 [(±SD: 53.2 ± 10.5), (range 35-64)] years with deficient serum VD level (<30 ng/mL) were included in the study. Participants were followed up for one year, with monitoring at 3-, 6-, 9- and 12-months. At the initial baseline visit, a complete medical examination was conducted, and blood was drawn for laboratory tests for above biochemical and hormonal variables under examination. Participants received an initial VD (Ergocalciferol; oral solution 600 000 IU/1.5 ml), and followed a VD treatment regime thereafter. At the four follow up visits (3, 6, 9 and 12 months), blood was collected, and patients' erectile function was evaluated by IIEF-5 questionnaire. MAIN OUTCOME MEASURES: During the follow up visits, all the biochemical and hormonal (TT, estradiol and luteinizing hormones, HbA1c, serum lipids profile) were assessed, and patients' erectile function was evaluated by IIEF-5 questionnaire. RESULTS: Patients' mean age was 53.2 ± 10.4 years. Serum VD exhibited significant increments (p <0.001) from baseline (15.16 ± 4.64 ng/mL), to 3 (31.90 ± 15.99 ng/mL), 6 (37.23 ± 12.42 ng/mL), 9 (44.88 ± 14.49 ng/mL) and 12 months (48.54 ± 11.62 ng/mL), and there was significant stepladder increases in both serum TT level (12.46 ± 3.30 to 15.99 ± 1.84 nmol/L) and erectile function scores (13.88 ± 3.96 to 20.25 ± 3.24) (p <0.001 for both). We also observed significant stepladder decreases in estradiol (87.90 ± 27.16 to 69.85 ± 14.80 pmol/L, p = 0.001), PTH (from 58.52 ± 28.99 to 38.33 ± 19.44 pg/mL, p <0.001) and HbA1c levels (7.41 ± 2.85 to 6.66 ± 1.67%, p = 0.001). Mean BMI significantly decreased from 33.91 ± 6.67 to 33.14 ± 6.35 kg/m2 (p = 0.001); and PSA values significantly increased from 0.59 ± 0.30 to 0.82 ± 0.39 ng/mL (p <0.001) at the end of the 12 months' follow-up. There were no changes in LH levels. CONCLUSION: This study demonstrated that VD treatment improves testosterone levels, metabolic syndrome and erectile function in middle-aged men. More randomized placebo-controlled interventional trials of VD treatment in patients with the metabolic syndrome and low TT could assist in uncovering the putative roles of VD.

BACKGROUND: Late-onset hypogonadism (LOH) presents with low serum testosterone (TT) levels and sexual and nonsexual symptoms. Erectile dysfunction affects a man's self-esteem and as a result partner relationship and quality of life. OBJECTIVES: To investigate the andrological clinical profile outcomes of testosterone therapy (TTh) in men (n = 88) with symptomatic LOH complaints and symptoms. MAIN OUTCOME MEASURES: Erectile function was assessed using the International Index of Erectile Function-5 questionnaire at baseline and at 6 and 12 months of TTh. In addition, penile length was measured at baseline and 12 months. We also evaluated nocturnal penile tumescence (NPT, using RigiScan) and blood flow of cavernous arteries (penile Doppler ultrasonography) at baseline and 12 months of TT. MATERIALS AND METHODS: Eighty-eight LOH men (Mage 51.1 years) with erectile dysfunction, all with serum TT <10.4 nmol/L before TTh. Patients received intramuscular long-acting testosterone undecanoate for 12 months. RESULTS: Following TTh, in all patients, serum TT levels were restored within 3 months to normal levels. Compared with baseline values, erectile function significantly improved at 6 (mean score increase 1.95) and 12 months (mean score increase 2.16). No significant changes in penile length were observed. NPT significantly improved at 12 months in terms of both the frequency (mean increase 1.27 times) and duration of rigidity (mean increase 5.12 min). As regards the blood flow of the cavernous arteries, we observed a significant improvement (decrease of 1.16 cm/s) and end diastolic velocity of the penile arteries. CONCLUSION: TTh in men with LOH resulted in improvement of the erectile function, NPT, and to some extent the blood flow of the cavernous arteries.

PURPOSE: Ischemic priapism, which is a compartment syndrome, needs urgent treatment in order to nourish corpora cavernosa. As the first step, the aspiration of blood and/or the irrigation of the cavernosal bodies are performed to prevent fibrotic activity and secure erectile capability. While performing aspiration and irrigation, there are some risks of the procedure in which most refrained one is cardiovascular side effects of adrenergic agonists. We aimed to evaluate extracorporeal transient distal penile corporoglanular shunt technique in place of aspiration/ irrigation techniques for early ischemic priapism treatment. MATERIALS AND METHODS: In this transient shunt technique, a sterile closed system blood collection set (BD Vacutainer, Cat. No.: 367282; NJ, USA), which has two 21G needles, was used. The length of the needle and tubing was 19 mm. (0.75 inch) and 178 mm. (7 inches), respectively. This blood collection set was designed to be used not only for blood collection but can also be used for short term infusions (maximum 2 hours). RESULTS: Ten patients out of fifteen with early ischemic priapism were successfully treated with this transient shunt technique. The permanent detumescence achieved in the first 10 minutes in nine out of fifteen patients.No additional procedure needed after the disappearance of rigidity in successfully treated patients. The permanent detumescence achieved in the first 10 minutes in nine out of fifteen patients. CONCLUSIONS: We demonstrated that this extracorporeal transient shunt technique gets some advantages over aspiration and irrigation in early ischemic priapism treatment. Our results indicate thatthe presented technique to be offered for the patients with an ischemic priapism episode of no more than 7 hours.

OBJECTIVES: Penile prosthesis implantation is the final treatment option for patients who have erectile dysfunction. Most of the patients use their penile prosthesis successfully and frequently for penile-vaginal intercourse. Previous literature showed that decrease in sexual activity resulted in decreased serum testosterone levels and vice versa. The aim of this study was to examine the impact of sexual activity on serum sex hormone levels after penile prosthesis usage. MATERIAL AND METHODS: In this study, we examined sixtyseven patients for their sex hormone changes who had penile prosthesis surgery 2.7 ± 1.5 years ago. RESULTS: Patients were using their penile prosthesis for sexual activity with a mean of 9.9 ± 5.7 times per month. Dehydroepiandrosterone sulfate was significantly higher compared to pre-surgery results (5.3 ± 2.6 vs 4.5 ± 2.9; p = 0.031). Mean serum total testosterone levels of patients before and after penile prosthesis usage were clinically significant 15.78 ± 4.8 nmol/L and 16.5 ± 6.1 nmol/L, respectively. Mean serum luteinizing hormone levels of patients before and after penile prosthesis usage were 3.98 ± 2.16 IU/L and 5.47 ± 4.76 IU/L, respectively. No statistical significance difference was observed in the mean total and free testosterone, estradiol and luteinizing hormone levels between pre- and post-surgery. CONCLUSION: This study results demonstrated that sexual activity changed sex hormone levels positively among those men who were implanted penile prosthesis because of erectile dysfunction.
RESUMO
INTRODUCTION: The aim of this article was to describe our experience in using rotating saw and also combination of the instrument with 4-needle aspiration. METHODS: A comprehensive review of the literature was performed using PubMed. "Penile strangulation, -constriction, -incarceration, -entrapment" were used as search terms, and a manual bibliographic review of cross referenced items was performed. RESULTS: Search results yielded nearly 70 cases of penile strangulation caused by a variety of objects. Various instruments have been described in the literature for their safe removal, each with its own pros and cons. CONCLUSIONS: Penile strangulation should be accepted as a self-induced priapism and managed as an emergency in order to preserve erectile function and to prevent penile necrosis. Surgical creativity and patience are necessary in order to have a successful outcome.

INTRODUCTION: Ureteroscopy has improved from the first use of ureteroscope in the 1970' s. Although the success rate increased in the last years, new treatment techniques are being developed for impacted and large proximal ureter stones (2). Pneumatic lithotripsy has high efficiency with low complication rates. However, in case of steinstrasse and large (> 1 cm) ureter stones, fragmented small stones may obstruct insertion of a ureteroscope after initial lithotripsy. In order to triumph over this issue, multiple ureteroscopic passages and manipulations needed for extraction of these small stones by forceps or basket catheters. The overall incidence of stricture was found upto 14.2% when the fragments were removed with a grasping forceps or a basket. We present our technique to disperse small fragmented stones in order to contact non-fragmented rest stone. MATERIALS AND METHODS: Ureteral lithotripsy was performed with an 8-9.8F semirigid ureteroscope using a pneumatic lithotripter (Swiss LithoClast, EMS, Nyon, Switzerland). The stone was fragmented into small pieces as small as 2-3 mm. by pneumatic lithotripter. Eventually, these fragmented stones interfered with vision and the lithotripter to get in touch with the rest stone. After fragmenting distal part of the large stone, the ureteroscope was pulled back out of ureter. While pulling back, the operating channel was closed and irrigation fluid was flowing in order not to decrease pressure behind the stones. Simultaneously, a person tilted the operating table to about 30 in reverse Trendelenburg position. When the ureteroscope was out of ureteral orifice, the operating channel was opened and irrigation fluid was stopped. This maneuver aided decreasing pressure in the bladder more rapidly in addition to feeding tube. Stone dust and antegrade fluid flow were easily seen out of the ureteral orifice. Ureteroscope was re-inserted after 30-60 seconds. While reaching the rest of the stone, small stone dust was seen at first. Bigger stones were approximately 3-5 cm distal to the original place of the stone. When the non-fragmented rest stone appeared, there were no blocking fragmented stones. Insertion of the ureteroscope was easy and we could go on with the lithotripsy procedure. CONCLUSIONS: In comparison to standard position, tilting and rapid decrease in pressure by pulling back the ureteroscope made gravity and negative pressure more effective.

INTRODUCTION: Penile prosthesis implantation is one of the treatment choices that is kept for patients who were not satisfied with other treatments. Although penile prosthesis satisfaction rates are higher, there are some dissatisfied patients. The patients' reasons are mostly shortness and softness of implanted prosthesis. It was previously demonstrated that penile axial rigidity of more than 500 grams is enough for successful vaginal intromission. To our knowledge, there is no study comparing axial rigidity of penile prosthesis and satisfaction. OBJECTIVES: The aim of this study was to examine whether axial rigidity of penile prosthesis had impact on patient and partner satisfaction. MATERIALS AND METHODS: We enrolled one hundred patients who were implanted penile prosthesis before to evaluate their penile axial rigidity. We used Rigidometry (by using the digital inflection rigidometer) to assess the minimal axial pressure to bend the implanted penis. RESULTS: We demonstrated that mean axial pressure to bend the implanted penis was 984.8 ± 268.7 grams. Overall satisfaction score with the penile prosthesis implant was 4.55 and 4.49 (out of 5) in patients and partners, respectively. In total, seven men were unsatisfied with their implant and reported a mean satisfaction score of 0.6 ± 0.48 (out of 5). All prostheses types showed good and more than 500 grams axial rigidity. The patients with Ambicor type, which were buckled at about 710.5 grams, showed worse satisfaction rates in comparison to other prostheses in two patients. Digital inflection rigidometer results of other penile prosthesis types in unsatisfied patient were 842.0, 872.0, 887.0 and 920 g. in CX700, Titan, Genesis and Titan OTR, respectively. CONCLUSION: We demonstrated that dissatisfaction rate was highest in Ambicor prosthesis implanted patients. Additionally, patients with 3-piece penile prosthesis were more satisfied than 2-piece or malleable ones, interestingly, although some cases had lower axial rigidity results.
