Melatonin protects kidney against apoptosis induced by acute unilateral ureteral obstruction in rats.

INTRODUCTION: To investigate whether there was a protective effect of melatonin on apoptotic mechanisms after an acute unilateral obstruction of the kidney. MATERIAL AND METHODS: A total of 25 rats consisting of five groups were used in the study, designated as follows: Group 1: control, Group 2: sham, Group 3: unilateral ureteral obstruction treated with only saline, Group 4: unilateral ureteral obstruction treated with melatonin immediately, and Group 5: unilateral obstruction treated with melatonin one day after obstruction. Melatonin was administered as a 10 mg/kg dose intraperitoneally. The kidneys were evaluated according to the apoptotic index and Ki-67 scores. RESULTS: Comparison of all obstruction groups (Group 3, 4, and 5), revealed that the apoptotic index was significantly higher in Groups 1 and 2. Despite melatonin reduced apoptotic mechanisms in Groups 4 and 5, there was no significant difference between Groups 4 and 5 in terms of the reduction of apoptosis. However, the reduction of apoptosis in the melatonin treated group did not decrease to the level of Groups 1 and 2. CONCLUSIONS: Despite melatonin administration, which significantly reduces the apoptotic index occurring after acute unilateral ureteral obstruction, the present study did not observe a return to normal renal histology in the obstruction groups.

The effectiveness of local steroid injection after internal urethrotomy to avoid recurrence.

OBJECTIVE: Local steroid injection to the stricture region after internal urethrotomy (IU) is a promising technique to avoid the recurrence, although the effectiveness and safety of this technique is still controversial. We aimed to determine the efficacy and safety of local steroids as applied with the IU procedure. MATERIAL-METHOD: A total of 83 patients data with urethral stricture in men were examined retrospectively. Patients classified in two groups who had steroid injection with internal urethrotomy or not. Metil prednisolone 40 mg was injected with transurethral injection needle in the stricture region at the 5, 7 and 12 o'clock sites at the same session with internal urethrotomy. Procedure was considered successful if patient did not report any voiding difficulty and maximum flow rate > 15 mL/second for a voided volume of at least 150 mL after removal of the catheter. Patient's age, time to recurrence, previous recurrences were evaluated. RESULTS: The mean age was 56.4 (18-83) years. Of those patients 33/83 had recurrent stenosis. Nineteen out of these 33 recurrent stenosis patients were treated with local steroid injection and 14/33 had no injection. Only two patients of the steroid treated group had recurrence. Despite that 12 patients had recurrence in the steroid non-treated group. Also the primary stenosis patients showed no recurrence at the steroid+ IU group. CONCLUSIONS: The use of local steroids with IU seems to decrease the high stricture recurrence rate following IU. When local steroids were administered with complementary intention, the disease control outcomes are encouraging. Further robust comparative effectiveness studies are now required.

What is harmful for male fertility: cell phone or the wireless Internet?

In this study, we aimed to assess the potential harmful effects of radiofrequency-electromagnetic radiation on sperm parameters. We requested semen for analyses from the male patients coming to our infertility division and also asked them to fill out an anonymous questionnaire. We queried their mobile phone and wireless Internet usage frequencies in order to determine their radiofrequency-electromagnetic radiation exposure. A total of 1082 patients filled the questionnaire but 51 of them were excluded from the study because of azoospermia. There was no significant difference between sperm counts and sperm morphology excluding sperm motility, due to mobile phone usage period, (p = 0.074, p = 0.909, and p = 0.05, respectively). The total motile sperm count and the progressive motile sperm count decreased due to the increase of internet usage (p = 0.032 and p = 0.033, respectively). In line with the total motile sperm count, progressive motile sperm count also decreased with wireless Internet usage compared with the wired Internet connection usage (p = 0.009 and p = 0.018, respectively). There was a negative correlation between wireless Internet usage duration and the total sperm count (r = -0.089, p = 0.039). We have also explored the negative effect of wireless Internet use on sperm motility according to our preliminary results.

The comparison of the influence between two different bowel preparation methods on sepsis after prostate biopsies.

INTRODUCTION: Transrectal ultrasonography (TRUS) guided prostate needle biopsy has been performed to diagnose and stage prostate cancer for many years. There are many different bowel preparation protocols to diminish the infectious complications, but there is no standardized consensus among urologists. Therefore, we aimed to assess two different bowel preparation methods on the rate of infectious complications in patients who underwent TRUS-guided prostate biopsy. MATERIAL AND METHODS: A total of 387 cases of TRUS-guided prostate biopsy were included in this retrospective study. All patients received antibiotic prophylaxis with ciprofloxacin (500 mg) twice a day orally for 7 days starting on the day before the biopsy. The patients were divided into two groups according to the bowel preparation method used. Patients (Group 1, n = 164) only received self-administrated phosphate enema) on the morning of the prostate biopsy. Other patients (Group 2, n = 223) received sennasoid a-b laxatives the night before the prostate biopsy. Infectious complications were classified as sepsis, fever (greater than 38°C) without sepsis, and other clinical infections. RESULTS: Major complications developed in 14 cases (3.8%), including 3 cases (0.8%) of urinary retention, and 11 (3%) infectious complications, all of which were sepsis. There were 3 and 8 cases of urosepsis in Group 1 and Group 2, respectively. There were no statistically significant differences between both Groups regarding to the rates of urosepsis (p = 0.358). CONCLUSIONS: Despite both methods of bowel preparation, sodium phosphate enema or sennasoid a-b calcium laxatives, before TRUS-guided prostate biopsy have similar effect on the rate of urosepsis, so both methods of bowel preparation can be safely used.

The association between serum follicle-stimulating hormone levels and the success of microdissection testicular sperm extraction in patients with azoospermia.

PURPOSE: To evaluate the predictive power of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, testicular biopsy histology and male age were evaluated with respect to the success of sperm retrieval in a microdissection testicular sperm extraction (microTESE) procedure, pregnancy and live birth rates. MATERIALS AND METHODS: We examined the data of 131 infertile men with non-obstructive azoospermia, who have undergone microTESE operation. The men were classified into two groups based on serum follicle-stimulating hormone (FSH) levels ≤ 15 mIU/mL (group 1) and > 15 mIU/mL (group 2). RESULTS: Group 1 consisted of 59 patients (mean age 36.2 ± 6.2 years) and group 2 consisted of 72 (mean age 38.8 ± 7.4 years) patients. Sperm retrieval and pregnancy rates were 66.1% and 16.9% in normal FSH group, respectively. These parameters were higher than those of men with FSH > 15 (43% and 8.3%, respectively). Only 128 patients had histopathological diagnosis. Sperm was retrieved from 12/30 (40%) patients with maturation arrest, 9/29 (31.03%) patients with seminiferous tubules atrophy, 14/40 (35%) patients with sertoli cell only syndrome and 13/13 (100%) of patients with hypospermatogenesis. There was no statistically significant difference in pathological diagnosis between pregnancy and live birth rates. CONCLUSION: These results demonstrate that there is a significant difference with sperm retrieval, pregnancy rates and live birth rates comparing the FSH levels. Histopathological findings did not associate with successful microTESE, pregnancy rates and live birth rates.

Bladder cancer invasion predictability based on preoperative neutrophil-lymphocyte ratio.

An increased pretreatment neutrophil-lymphocyte ratio (NLR) is associated with poor prognosis in colorectal, gastric, and ovarian cancer; malignant mesothelioma; and renal cell carcinoma. The present study aims to define the predictive value of preoperative peripheral blood count NLR in non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive disease (MIBC) patients. There were in total 291 patients, 241 males and 50 females. Out of these, 156 male and 36 female patients were in the NMIBC group and 85 male and 14 female patients in the MIBC group. In the NMIBC group, 172 patients had low-grade and 20 high-grade papillary urothelial carcinoma. The mean age of the patients in the NMIBC group was 64 ± 13, ranging from 27 to 97. The mean age of the patients in MIBC group was 70.5 ± 10, ranging from 27 to 95. A statistically significant relation between patient ages and tumor invasiveness was determined (p = 0.023, 95 % confidence interval (CI) 63.3-66.7). The mean tumor size of the NMIBC group was 2.1 ± 1.09 (cm) (range 0.5-8), and of MIBC group 3.6 ± 1.5 (cm) (range 0.8-9). There was a statistically significant relation between the tumor size and invasiveness (p = 0.002, 95 % CI 2.8-4.4). In the NIMBC group, 149 (77.6 %) of them have NLR ≤ 2.5 and 43 (22.4 %) have NLR > 2.5. Also, in MIBC, 67 (67.7 %) of them have NLR ≤ 2.5 and 32 (32.3 %) have NLR > 2.5. The mean NLR in the NMIBC group was 2.4 ± 0.1 (range 0.08-6.49, 95 % CI 1.52-2.71) and in the MIBC 2.9 ± 0.2 (range 0.08-16.72, 95 % CI 1.67-2.97). In terms of NLR, there was a statistically significant difference between the NMIBC and MIBC groups (p = 0.028). Platelet-lymphocyte ratio (PLR) of the two groups was also analyzed. The PLR of the NMIBC group was 12.8 ± 15.1 (range 3.38-19.1) and of the MIBC 13.6 ± 8.78 (range 0.18-63), yet there was not any statistically significant difference (p = 0.810, 95 % CI 11.4-14.8) (Table 1). The correlation tests revealed a positive correlation between the age (r = 0.144, p = 0.024), tumor size (r = 0.193, p = 0.02), and tumor invasiveness NLR (r = 0.138, p = 0.031). NLR can be used to determine tumor invasiveness as a cost-effective, common, and simple biomarker in bladder cancer (BC).

Is polycystic ovarian syndrome a risk factor for urolithiasis?

Urinary stone disease is a complex multifactorial disorder influenced by both intrinsic and environmental factors. It is generally known that age and sex are risk factors for urinary stone disease. Also men have higher mean urinary oxalate concentrations than women. In addition, in animal and human studies, testosterone has been shown to increase the formation of urinary stones. This suggests that sex hormones are considered to be involved in the pathogenesis of stone disease. Polycystic ovary syndrome (PCOS) is one of the most frequent endocrine disorders of women in the reproductive age, affecting 5-10 % of women in this life span. It is characterized with chronic anovulation\oligo-ovulation, clinical or biochemical evidence of hyperandrogenism and polycystic ovaries on ultrasound examination. Hyperandrogenism, the main feature of PCOS, may trigger the urinary stone formation besides hirsutism, alopecia and acne. Therefore, we hypothesize that PCOS accompanied by hyperandrogenism may be a risk factor in the formation of urinary stone disease.

Helicobacter pylori seroprevalence in patients with chronic prostatitis: a pilot study.

OBJECTIVE: This study investigated the possible relationship between Helicobacter pylori infection and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). The rate of seropositivity for antibodies against H. pylori was determined in a cohort of subjects with CP/CPPS and prostatitis-free control subjects. MATERIAL AND METHODS: Sixty-four consecutive patients with CP/CPPS and 55 randomly selected asymptomatic men were recruited to the study. Blood samples from enrolled patients and control subjects were analysed using an enzyme-linked Immulite analyser immunoglobulin G serological test for H. pylori diagnosis. Prostate volume, prostate-specific antigen level, maximum urinary flow rate, and International Prostate Symptom Score (IPSS) and National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score of the subjects were also determined. The results were analysed with chi-squared and Student's t test and statistical analysis was carried out using SPSS software. RESULTS: There were no significant differences in age and social status between the CP/CPPS and control groups (p > 0.05). Total NIH-CPSI score was significantly higher in the CP/CPPS group. Seropositivity for antibody against H. pylori was higher in the CP/CPPS than the control group (p < 0.05). CONCLUSIONS: This pilot study supports the hypothesis that H. pylori may play a role in CP/CPPS. The infection may be related to the immune response and increased cytokines in seminal plasma and/or expressed prostatic secretion. However, no study has investigated the relationship between CP/CPPS and H. pylori stool antigen positivity. This study showed that H. pylori seropositivity is high in CP/CPPS patients, but this needs to be confirmed by other studies.

The evaluation of clitoral blood flow and sexual function in elite female athletes.

INTRODUCTION: Clitoral blood flow measurements using clitoral color Doppler ultrasound have been performed with increasing frequency either in order to assessment of female sexual function/dysfunction. The trials to evaluate the sexual function in healthy subjects, especially in the subgroup of female elite athletes, are limited. AIM: The aim of the study was to evaluate whether elite female athletes and sedentary healthy females differ in their clitoral blood flow and sexual function as an expression of their physical fitness status. METHODS: Twenty-five female elite athletes (Group I) and healthy female subjects (Group II) were enrolled as volunteers in the study. All women were instructed to complete the Female Sexual Function Index (FSFI) questionnaire. Each subject underwent high definition color Doppler ultrasonography to measure the clitoral blood flow parameters. Main Outcome Measures. The effect of physical activity on clitoral blood flow and sexual life in women. RESULTS: Mean age, mean age of menarche, mean marriage age, and body mass index were similar for both groups. In Group I, the mean peak systolic velocity and end-diastolic velocity were higher than those of Group II, whereas the mean RI was similar for both groups. There were statistically significant differences for total FSFI score and all domain scores, except desire domain, between both groups. CONCLUSION: In elite female athletes as compared with sedentary healthy females, better clitoral blood flow and better sexual function were demonstrated. Therefore it seems superior physical fitness correlates with better sexual function.

An insidious risk factor for cardiovascular disease: benign prostatic hyperplasia.

Patients with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTSs) have a considerably higher prevalence of cardiovascular disease (CVD) than the general population in old age. Many hypotheses have been created to explain traditional clinical risk factors of CVD, including age, male gender, cigarette smoking, inheritance, high blood pressure (BP), obesity, elevated fasting plasma glucose, diabetes mellitus, dyslipidemia, decreased physical activity and metabolic syndrome; or nontraditional risk factors such as oxidative stress, inflammation, vascular calcification, malnutrition, homocysteine and genetic variation. Although these risk factors are important in CVD pathophysiology and clinical presentation, there is still no single theory sufficient to provide an adequate explanation for all the properties of CVD. We speculate that by causing nocturia-induced sleep disturbances, BP variability, increased sympathetic activity, non-dipping BP variations; BPH may be an insidious risk factor for CVD. Benign prostate hyperplasia may be related to increased BP, coronary ischemic hearth disease or other cardiovascular pathologic conditions. This attention on BPH may produce a new approach to the diagnosis and treatment of CVD. Although the underlying mechanisms are still exactly unclear, further prospective randomized controlled studies are needed to identify if patients with BPH/LUTS is higher risk for CVD.

Ovarian apoptosis after shock wave lithotripsy for distal ureteral stones.

The objective of this study is to identify any apoptotic effect of shock wave lithotripsy (SWL) for distal ureteral stones on ovarian tissue. Twenty-one female New Zealand White rabbits were divided into three groups of seven rabbits each: I (control), and II, III (treated and killed 14 and 28 days after SWL, respectively). The left distal ureteral segment of the anesthetized (ketamine HCl, 20 mg/kg) animals in groups II and III was exposed to 1,500 shock waves at 17 kV. Localization of the distal ureteral segments was achieved following contrast medium (Iohexol 300 mg of I/ml) injection. The animals were killed on day 14 or 28 after SWL, and the ovaries were removed. The follicle number with apoptotic changes in ovarian tissue was compared with control group. Apoptotic changes were determined by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end-labeling (TUNEL) method. No increased apoptosis was detected in all groups. The mean number of TUNEL-positive follicle in groups I, II and III was 9.3 +/- 2.9, 8.1 +/- 2.6 and 8.7 +/- 2.9, respectively. There were no statistically significant differences among all groups regarding the number of TUNEL-positive follicle (P = 0.647). Also, no histomorphological change other than apoptosis was detected in the study groups. In conclusion, SWL treatment for distal ureteral stones does not induce apoptotic changes on ovarian tissue.

Curcumin protects against ischemia/reperfusion injury in rat kidneys.

OBJECTIVES: Renal ischemia followed by reperfusion leads to acute renal failure in both native kidneys and renal allograft. We investigated the effect of curcumin on ischemia-reperfusion (I/R) injury and the antioxidant effects of curcumin in rats. METHODS: Thirty rats were randomly divided into five experimental groups (control, sham, curcumin, I/R and I/R+curcumin, n=6 each). Curcumin was administered (200 mg kg(-1)) orally to curcumin and I/R+curcumin groups for 7 days. Then, the rats were subjected to bilateral renal ischemia for 45 min and followed by reperfusion for 24 h. All rats were killed and kidney function tests, serum and tissue nitric oxide (NO), protein carbonyl (PC), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels were determined. Histopathological examinations were also performed. RESULTS: Curcumin significantly improved the urea and cystatin C levels in I/R+curcumin group compared to I/R group (p<0.05). Reduction of serum GSH-Px was significantly improved by curcumin (p<0.001), but SOD enzyme activity did not alter (p>0.05). Treatment with curcumin also resulted in significant reduction in serum and tissue MDA, NO and PC and for tissue that were increased by renal I/R injury (p<0.001 for serum and p<0.05 for tissue, respectively). In histological examination, the rats treated with curcumin had nearly normal morphology of the kidney. CONCLUSIONS: Based on our results, it can be concluded that curcumin protects the kidneys against I/R injury via its antioxidant effects.

Nigella sativa protects against ischaemia/reperfusion injury in rat kidneys.

BACKGROUND: Renal ischaemia followed by reperfusion leads to acute renal failure in both native kidneys and renal allografts, which is a complex pathophysiologic process involving hypoxia and free radical (FR) damage. The oil of Nigella sativa (NSO) has been subjected to considerable pharmacological investigations that have revealed its antioxidant activity in different conditions. But there is no previously reported study about its effect on ischaemia/reperfusion (I/R) injury of kidneys. The aim of this study was to investigate the possible effects of NSO in I/R-induced renal injury in rats. METHODS: Thirty healthy male Wistar albino rats were randomly assigned to one of the following groups: control, sham, I/R, NSO+I/R, I/R+NSO and NSO. I/R, NSO+I/R and I/R+NSO rats were subjected to bilateral renal ischaemia followed by reperfusion and then all the rats were killed and kidney function tests, serum and tissue oxidants and antioxidants were determined and histopathological examinations were performed. RESULTS: Pre- and post-treatment with NSO produced reduction in serum levels of blood urea nitrogen (BUN) and creatinine caused by I/R and significantly improved serum enzymatic activities of superoxide dismutase (SOD) and glutathion peroxidase (GSH-Px) and also tissue enzymatic activities of catalase (CAT), SOD and GSH-Px. NSO treatment resulted in lower total oxidant status (TOS) and higher total antioxidant capacity (TAC) levels and also significant reduction in serum and tissue malondialdehyde (MDA), nitric oxide (NO) and protein carbonyl content (PCC) that were increased by renal I/R injury. The kidneys of untreated ischaemic rats had a higher histopathological score, while treatment with NSO nearly preserved the normal morphology of the kidney. CONCLUSIONS: In view of previous observations and our data, with the potent FR scavenger and antioxidant properties, NSO seems to be a highly promising agent for protecting tissues from oxidative damage and preventing organ damage due to renal I/R.

Oral beta-glucan protects kidney against ischemia/reperfusion injury in rats.

BACKGROUND: Ischemia-reperfusion (I/R) injury is one of the leading causes of acute renal failure. Beta-(1-->3)-glucans are glucose polymers with a variety of stimulatory effects on the immune system. We designed this study to determine the possible protective effect of the orally administered soluble beta-glucan against I/R injury. METHODS: 30 rats were randomly divided into 5 experimental groups (control, sham operated, beta-glucan, I/R and I/R+beta-glucan groups, n = 6 each). Beta-glucan was administered orally to 6 rats of the beta-glucan and I/R+beta-glucan groups. The rats were subjected to bilateral renal ischemia followed by reperfusion in the I/R and I/R+beta-glucan groups. All of the rats were then sacrificed and kidney function tests, serum and tissue oxidants and antioxidants were evaluated. RESULTS: The serum urea and cystatin C levels were significantly higher in the I/R group compared to the I/R+beta-glucan group (p < 0.01). The serum and tissue antioxidant markers (SOD, GSH-Px) were significantly lower in the I/R group than the I/R+beta-glucan group (p < 0.01). The serum oxidant markers (NO and PC) were significantly higher in the I/R group than the I/R+beta-glucan group (p < 0.01). CONCLUSION: Based on the present data, we conclude that increased antioxidants and decreased oxidants modulated by beta-glucan attenuated the renal I/R injury.

The effects of shock waves on lung tissue in acute period: an in vivo study.

The acute effects of extracorporeal shock waves on lung morphology were studied by light microscopy in 30 New Zealand rabbits. The left kidneys of the ten animals were exposed to 2,000 shockwaves at 18 kV under anesthesia (ESWL group). Ten rabbits were in the control group; an intramuscular anesthetic agent (ketamine) and intravenous contrast media were administered to ten animals in the sham group. Localization of the left kidneys was achieved following contrast medium injection through an ear vein under fluoroscopic control. The animals were killed after the ESWL procedures and the lungs were removed. Edema, emphysema, hemorrhage, congestion, inflammation, loss of normal structure, and epithelial desquamation were determined and graded between 0 and 3 in all areas of both lungs. In order to determine whether proximity has any effect on the histopathological changes, left and right lungs were evaluated separately as well as upper and lower lobes. We found that ESWL exposed to kidney also affects all areas of the lungs in a rabbit model.

Is single-dose fosfomycin trometamol a good alternative for asymptomatic bacteriuria in the second trimesterof pregnancy?

Untreated asymptomatic bacteriuria has been associated with acute pyelonephritis, which may have a role in many maternal and fetal complications. Acute pyelonephritis in pregnancy is related to anemia, septicemia, transient renal dysfunction, and pulmonary insufficiency. A randomized study was conducted to assess the clinical and microbiological efficacy of a single dose of fosfomycin trometamol for the treatment of asymptomatic bacteriuria in the second trimester of pregnancy compared with a 5-day regimen of cefuroxime axetyl. Forty-four women received fosfomycin trometamol and 40 women received cefuroxime axetyl. There were no statistically significant differences between both groups regarding the mean age and mean duration of pregnancy. Therapeutic success was achieved in 93.2% of the patients treated with fosfomycin trometamol vs 95% of those treated with cefuroxime axetyl. A single dose of fosfomycin trometamol is a safe and effective alternative in the treatment of asymptomatic urinary tract infections in the second trimester of pregnancy.

Protective role of natural antioxidant supplementation on testicular tissue after testicular torsion and detorsion.

OBJECTIVES: To investigate the impact of garlic extract (GE), which is known for its antioxidant activity, on a testicular torsion/detorsion model in animals and to help understand how to prevent both ischemic and reperfusion injuries after testicular torsion and detorsion. MATERIAL AND METHODS: Six groups of rats (n=7 in each group) were used. The animals in the control group (Group I) did not receive any treatment. The animals in the sham group (Group II) underwent scrotal incision and testicular fixation only. The animals in Groups III-VI underwent 720 degrees of left testicular torsion for 2 h; subsequent detorsion was performed for 2h in Groups IV and VI only. Animals in Groups V and VI were treated exactly the same as those in Groups III and IV, respectively except that they were pretreated with oral GE for 5 days at a dosage of 5 ml/kg. Both testicles in all rats were removed and tissue malondialdehyde (MDA) levels and enzymatic activities of xanthine oxidase (XO) were studied, in addition to a histological evaluation after hematoxylin-eosin staining. RESULTS: Testicular MDA levels and XO activities were higher in Group III compared to Group II (p<0.05). Pretreatment with GE prevented these increases. Detorsion caused more damage and resulted in a further increase in MDA levels but MDA levels were not increased in animals pretreated with GE. Histologically, torsion caused some separation between germinative cells in the seminiferous tubules, which became much more prominent in Group IV and was attenuated by GE pretreatment. There were no significant changes in any of the above-mentioned enzymatic activities or histopathologic changes in the contralateral testicle in any of the groups. CONCLUSIONS: We believe that both testicular torsion and detorsion result in testicular tissue damage by means of lipid peroxidation, which is evident by an increase in the tissue levels of MDA. Dietary supplementation with GE seems to attenuate the generation of toxic free radicals, as evidenced indirectly by low tissue MDA levels.

Urethral adenocarcinoma mimicking urethral caruncle.

Urethral caruncles are considered as benign tumors. They need to be treated surgically; specimens should carefully be evaluated for the presence of any malignancy. We are presenting a 57-year-old female patient with a urethral lesion that looks like caruncle, but histopathologic examination of the excised lesion was reported as urethral adenocarcinoma.
