Impact of high visceral adiposity index associated with metabolic syndrome on erectile function in sexually active men: Results of a cross-sectional study.

AIMS: Erectile dysfunction (ED) is a common condition affected by many factors. We aimed to show the impact of the metabolic syndrome (MeTS) on male sexual function based on visceral adiposity index (VAI). METHODS: Participants who met MeTS criteria (Group 1, n = 96) and did not meet MeTS criteria (Group 2, n = 189) were included in this cross-sectional study. The MeTS diagnosis was made in the presence of at least 3 of the following criteria: fasting serum glucose level higher than 100 mg/dL, HDL cholesterol level below 40 mg/dL, triglyceride level higher than 150 mg/dL, waist circumference higher than 102 cm and blood pressure higher than 130/85 mmHg. Demographic data were recorded; biochemical and hormonal tests were measured. Erectile and other sexual function scores were recorded. The VAI was calculated using the [(Waist Circumference/39.68) + (1.88 × body mass index)] × triglyceride/1.03 × 1.31/HDL formula. RESULTS: Mean age, smoking volume, testosterone (T) and testosterone/estradiol (T/E2 ) ratios of the groups were similar (P > .05). The mean VAI was two-fold higher in patients in Group 1 (P < .001) and erectile function score was lower in Group 1 than Group 2 (P = .001). Other sexual function scores were similar (P > .05). The METS was associated with an increased risk of ED (P = .001). Logistic regression analysis showed that each integer increase in the VAI was associated with a 1.4-fold increased risk of ED (P < .001). Higher T values were associated with a better erectile function (P = .03). For the VAI = 4.33, receiver-operating characteristic analysis showed a sensitivity of 89.6% and specificity of 57.7%. CONCLUSION: Compared with non-MeTS, the presence of MeTS has emerged as a risk factor for patients with ED with high VAI levels while the other sexual functions are preserved. Management of ED patients with MeTS should cover a comprehensive metabolic and endocrinological evaluation in addition to andrological work up.

Association of Abl interactor 2, ABI2, with platelet/lymphocyte ratio in patients with renal cell carcinoma: A pilot study.

There are many unknown aspects of the pathogenesis of renal cell carcinoma (RCC). The aim of the current study was to define new RCC-related genes and measure their associations with RCC and clinical parameters, especially platelet/lymphocyte ratio which may be an independent predictor of prognosis in patients with RCC and other forms of cancer. Via in silico analysis upon RCC-specific deleted genes in chromosome 3, four possible ceRNAs (ATXN3, ABI2, GOLGB1 and SMAD2) were identified. Then, the expression levels of these genes in tumour and adjacent healthy kidney tissues of 19 RCC patients were determined by real-time PCR. ATXN3 and GOLGB1 gene expression levels increased but ABI2 gene expression level decreased in tumour kidney tissues when compared to normal ones. ATXN3, ABI2 and GOLGB1 gene expression levels were significantly higher in Fuhrman grade 4 than other grades (P < .001). ABI2 gene expression levels were significantly associated with higher platelet/lymphocyte ratio of the patients with RCC (P < .05). ATXN3, ABI2 and GOLGB1 may predict higher RCC grades. Also, ABI2 may regulate platelet/lymphocyte ratio which may be an independent predictor of RCC and other forms of cancer.

A novel method for pain control: infiltration free local anesthesia technique (INFLATE) for transrectal prostatic biopsy using transcutaneous electrical nerve stimulation (TENS).

PURPOSE: To describe a novel method for the control of pain during prostate biopsies, infiltration free local anesthesia technique (INFLATE) for transrectal prostatic biopsies with no further needle insertions for local anesthetic infiltration. METHODS: A total of 138 men with elevated prostate-specific antigen levels and/or abnormal digital rectal examination findings were included in the study. Of the patients, 73 were assigned to the INFLATE group and 65 to the TRUS-PNB group. Demographic data, PSA levels, findings of digital rectal examinations, and multiparametric prostatic magnetic resonance imaging were recorded. In the INFLATE group, a two-channel TENStem eco basic device with two electrodes was used for pain control during the biopsy. For the TRUS-PNB group, 60 mg lidocaine gel was given intrarectally in addition to infiltration of a prilocaine and bupivacaine mixture (5 mL of 2% prilocaine + 5 mL of 0.25% bupivacaine). Pain perception was assessed using a linear numeric rating scale. RESULTS: The mean ages, BMIs, prostate volumes, and PSA levels were similar between the two groups (p > 0.05). Of the 56 participants with prostate adenocarcinoma, 28 were in the INFLATE group, and 28 were in the TRUS-PNB group with a 40.6% overall cancer detection rate. The mean preoperative and post-operative pain scores during probe insertion, biopsy and post-biopsy were similar between the groups (p > 0.05). CONCLUSION: The results of the study confirmed that INFLATE for transrectal prostate biopsy using a TENS device could safely and effectively be used for pain control with the advantage of two fewer needle attempts with no increase in significant complications.

Tr-KIT/c-KIT ratio in renal cell carcinoma.

Truncated KIT (tr-KIT) is an alternative variant of c-KIT protein. Previous studies have clearly documented that c-KIT was associated with various oncogenic processes in RCC. However, the biological significance of tr-KIT in RCC development and progression remains unclear. So, it was aimed to investigate the possible association between RCC and tr-KIT which is thought to activate some oncogenic pathways. In this study, Kidney Cancer cDNA Array containing a total of 48 cDNA samples from the normal kidney tissues of 9 healthy subjects and kidney tumor tissues of 10 stage-1, 5 stage-2, 13 stage-3 and 11 stage-4 RCC patients was used for gene expression analysis. Real-Time PCR method was used to measure tr-KIT/c-KIT expression ratios. tr-KIT/c-KIT expression ratio was compared between tumor and normal samples, and statistically correlated with the clinical parameters of RCC patients. tr-KIT/c-KIT expression ratio was approximately 4-times higher in tumor samples than control ones (p = 0.001). Also, tr-KIT/c-KIT expression ratio was approximately two, three and six times higher in Fuhrman nuclear grades 2, 3 and 4 than normal, respectively (p = 0.009). Moreover, clear cell and papillary RCC has a significantly higher level of tr-KIT/c-KIT expression ratio than chromophobe RCC (p = 0.016). In the current study, it was stated for the first time that tr-KIT/c-KIT expression ratio was up-regulated in RCC tissues, and high tr-KIT/c-KIT expression ratio was correlated with more aggressive clinical features and poor patient prognosis. Our results suggest that increased tr-KIT/c-KIT expression ratio might be useful as a prognostic marker for RCC patients.

Glutamate transporter SLC1A1 is associated with clear cell renal cell carcinoma

Background/aim: This study aimed to comparatively analyze the expression levels of the SLC1A1 gene in renal specimens from tumors and adjacent healthy kidney tissues of patients with clear cell renal cell carcinoma (ccRCC). Materials and methods: Nineteen patients diagnosed with ccRCC were included in the study. The expression levels of the SLC1A1 and GAPDH genes were measured in tumor and formalin-fixed paraffin-embedded (FFPE) tissue specimens from the adjacent healthy kidney of each subject. Via the GEPIA database, the distribution of SLC1A1 gene expressions in ccRCC and healthy kidney tissues was obtained. The relative expression of SLC1A1 was evaluated for the association with the clinical parameters of the patients. Results: The expression of the SLC1A1 gene was significantly higher in males than females (P = 0.029). Also, there were statistically significant associations between stages II­IV and Fuhrman grades 2­4 with respect to SLC1A1 gene expression (P < 0.001 for both). Moreover, low levels of red blood cell and hemoglobin counts were significantly associated with the SLC1A1 expression (P < 0.001 and P = 0.005, respectively). The expression of the SLC1A1 gene in tumor tissues increased approximately 3 times compared with normal kidney tissues (P < 0.05). According to the GEPIA database, SLC1A1 gene expression is significantly higher in ccRCC patients than healthy persons (P = 0.01). Conclusion: The change in the expression of SLC1A1 may be crucial for ccRCC pathophysiology.

Expression profiles of proto-oncogene TWIST1 and tumor metastasis suppressor gene LASS2 in bladder cancer.

Transcription factor proto-oncogene TWIST1 and tumor metastasis suppressor gene LASS2 have been reported to be involved in various carcinomas but their expression profiles and prognostic significances in bladder cancer are largely unknown. We aimed to determine these genes' expression levels both at mRNA and protein level in bladder cancer. mRNA expression levels of TWIST1 and LASS2 genes were examined using real-time quantitative PCR (qPCR) in human bladder tumors and paired normal adjacent tissues obtained from 44 patients. Protein expression profiles of both genes were detected by immunohistochemical staining in formalin-fixed and paraffin-embedded tissues from the same patients. The expression profiles of TWIST1 mRNA in bladder tumors were significantly lower than the normal adjacent tissues and linked to both the stage and the grade. The expression profiles of LASS2 mRNA in bladder tumors were also significantly lower than the normal adjacent tissues reflecting the potential tumor suppressor profile of the gene, independently from stage or grade. By immunohistochemistry, TWIST1 and LASS2 positive expression rates were found as 14.3% (6/42) and 38.1% (16/42), respectively. As potential molecular markers for bladder carcinoma, both TWIST1 and LASS2 transcripts seem to play role during the tumorigenesis and development of bladder cancer. Lack of a functional link and/or weak inverse link between TWIST1 and LASS2 transcripts and immunohistochemical findings may reflect the potential associations of transcription regulation mechanisms and merit further investigations. To the best of our knowledge, this is the first report investigating the combined expression profile of TWIST1 and LASS2 in bladder cancer both at mRNA and protein level.

The effect of dutasteride on microscopic and macroscopic changes of testosterone replacement treatment on prostate tissue.

Testosterone replacement therapy has a growing interest in daily practice; however, debates on its safety for prostate cancer still continue. Dutasteride-a 5α-reductase inhibitor-was shown to be effective in preventing prostate cancer. We therefore aimed to evaluate the effect of testosterone replacement therapy and dutasteride treatment on prostate tissue in castrated rats. Rats were randomised in four groups after bilateral orchidectomy as follows: Group I received testosterone + dutasteride, Group II received only testosterone, Group III had no medical treatment, and Group IV was the control group. After 3 months, rats were sacrificed and laboratory and histopathological examinations were performed. In Groups I and II, prostate volume, T and DHT levels were significantly higher compared to Group III and controls. Groups I and II had also significantly greater preneoplastic histopathological signs; however, in intergroup analyses, Group I showed less premalignant changes compared to Group II. We concluded that dutasteride was effective when combined with testosterone therapy in preventing premalignant histopathological changes in prostate tissue. Further evidence is needed to confirm our findings.

Promoter methylation analysis of CDH1 and p14ARF genes in patients with urothelial bladder cancer.

BACKGROUND/AIM: Urothelial bladder cancer arises from the accumulation of multiple epigenetic and genetic changes. We aimed to investigate the specificity and sensitivity of gene-specific promoter methylation of CDH1 and p14ARF genes in the early diagnosis of bladder cancer and compare those with other diagnostic tests in our population. PATIENTS AND METHODS: In the current study, 65 patients with urothelial bladder cancer and 35 controls without any history of cancer were recruited. Methylation profiles of CDH1 and p14ARF genes from tumor and urine samples were determined by methylation-specific polymerase chain reaction method. RESULTS: Methylation of CDH1 and p14ARF genes in tumor samples was 95.4% and 78.5%, respectively. The methylation frequencies were found to be 68.8% for CDH1 gene and 72.9% for p14ARF gene in urine samples. Sensitivities of CDH1, p14ARF and urine cytology were found to be 67.4%, 72.1% and 34.9%, respectively, while their specificities were 93.9%, 63.6% and 93.9%, respectively. CONCLUSION: Aberrant promoter methylation of CDH1 and p14ARF genes can be used to detect urothelial bladder cancer. In low-grade tumors, when compared with urine cytology, combined methylation analysis of CDH1 and p14ARF genes may not increase the sensitivity to identify malignant cells in urine samples.

Surgical treatment of posterior nutcracker syndrome presented with hyperaldosteronism.

Posterior nutcracker syndrome is caused by the compression of left renal vein between the abdominal aorta and the vertebral body. Most seen symptoms are haematuria, left flank pain, abdominal pain and varicocele. The nutcracker syndrome may lead to left renal vein thrombosis due to blood congestion within compression of the vessel. Both endovascular and open surgical interventions can relieve symptoms; however, traditional surgical repair is still considered as the gold standard. Here, we present the surgical treatment of a 36-year old female with complaints of hypertension, hyperaldosteronism and diagnosed with posterior nutcracker syndrome.

The role of ketotifen in the prevention of testicular damage in rats with experimental unilateral undescended testes.

The aims of this study conducted on rats were to determine mast cell (MC) proliferation on undescended testes (UDTs); whether there is a correlation between MC proliferation and testicular damage; and whether testicular damage can be prevented with administration of an MC blocker. Sixty-five newborn male rats were divided into three groups. During the neonatal period, unilateral UDTs were experimentally induced in Group 2 and Group 3. The rats in Group 3 were given 1 mg/kg/day ketotifen orally until the end of the study. Groups 2 (n=30) and 3 (n=15) were divided into groups of ten and five rats, respectively, each of which underwent bilateral orchiectomy in either the prepubertal, pubertal, or adult period. Group 1 (n=15) underwent a sham operation followed by bilateral orchiectomy, with five rats in each of the prepubertal, pubertal, and adult periods. Testicular MCs in the interstitial and subtubular areas, biopsy scores, interstitial connective tissue, seminiferous tubule (ST) diameters, and the basement membrane thickness of STs were evaluated. In Group 2 the ST diameters in the UDTs decreased, the number of MCs in the interstitial and subtubular areas increased, ST basement membranes thickened, and spermatogenesis decreased. The number of MCs in the interstitial and subtubular areas of the descended testes increased and spermatogenesis decreased. In Group 3, the number of MCs in the interstitial and subtubular areas decreased. In unilateral UDTs, the number of MCs in the interstitial and subtubular areas increased in both testes. Fibrosis developed in the ST basement membranes and interstitial areas, and spermatogenesis deteriorated. Testicular fibrosis may be prevented with administration of an MC blocker.

Comparison of demographic data in patients undergoing Percutaneous Nephrolithotomy in Southeastern Anatolia and the Black Sea region: A multicenter study.

OBJECTIVE: The aim of this study was to compare demographic data in adult patients undergoing percutaneous nephrolithotomy (PNL) for kidney stone disease in university hospitals from Southeastern Anatolia and the Black Sea regions. MATERIAL AND METHODS: The demographic data of 535 (53.3%) patients undergoing PNL from Gaziantep University, Department of Urology (GAUN group), and 468 (46.6%) patients undergoing PNL from Ondokuz Mayis University, Department of Urology (OMU group) were evaluated retrospectively. Patients' gender, mean age, stone laterality, and size and results of the stone analyses were compared. RESULTS: The mean patient ages were 40.94±13.33 (17-81) and 48.03±13.95 (17-81) years in the GAUN and OMU Groups, respectively, (p=0.0001). The mean stone size was 716.01±449.60 (100-3000) mm(2) and 612.7±445.87 (65-3220) mm(2) in the GAUN and OMU Groups, respectively (p= 0.0001). There were no statistically significant differences between the groups with respect to stone laterality (p=0.196), and gender of the patients (p=0.65). Stone analysis revealed that the distribution of stone composition was as follows in the GAUN group: Ca oxalate (90.19%), cystine (7.84%), uric acid (5.88%), and struvite (1.96%). In the OMU group, the stone composition was as follows: Ca oxalate (86.84%), cystine (1.34%), uric acid (13.15%), and struvite (9.21%). CONCLUSION: The incidence of kidney stone disease varies throughout Turkey based on etiological factors, and a higher incidence of kidney stone disease is observed in the Southeastern Anatolia region endemically. Lower mean ages and higher stone sizes in patients undergoing PNL in southeastern Anatolia suggest that geographic factors can affect stone disease.

Hypermethylation of TWIST1 and NID2 in tumor tissues and voided urine in urinary bladder cancer patients.

Bladder cancer like other cancers arises from the accumulation of many genetic and epigenetic changes that lead to the activation of proto-oncogenes or inactivation of tumor suppressor genes. We aimed to investigate the methylation patterns of Twist homolog 1 (TWIST1) and nidogen-2 (NID2) genes in bladder cancer. Fifty six histologically confirmed bladder tumor samples and paired 24 urine samples constituted the study group and was compared with 15 age- and gender-matched noncancerous individuals. DNA was purified from both tumor and urine samples. The methylation status of the two genes was analyzed by methylation-specific polymerase chain reaction (MSP) in both urinary bladder cell carcinoma samples and urine samples. Sensitivity and specificity values of the method were assessed and compared with the results of the cytology test. Methylation of TWIST1 and NID2 was detected in 98.2% and 96.4% of the tumor samples, and in 87.5% and 95.8% of the urine samples, respectively. The sensitivity of TWIST1 and NID2 genes (87.5% and 95.8% in urine samples, respectively), was higher compared with urine cytology (62.5%) for cancer detection. The sensitivity of any of the two genes was 88.8% (8/9) for low-grade cases. The sensitivity of urine cytology was 33.3% for the same low-grade cases. To be used in the early noninvasive diagnosis of bladder cancer, the combined methylation analysis of TWIST1 and NID2 genes may be a simple, noninvasive, sensitive, and specific method for detecting cancer cells in urine.

Development of a quality of life scale specific for patients with benign prostatic hyperplasia.

PURPOSE: The improvement of quality of life (QoL) should be the major concern in any proposed treatment modality for any disorder. The objective of this study was to develop a new easy to use benign prostatic hyperplasia (BPH)-specific QoL scale that may guide the treatment policy in BPH. METHODS: A total of 118 items addressing BPH-specific QoL were produced. After an elimination process, a 20-question scale was developed. This new scale, Short Form (SF)-36 and International Prostate Symptom Score (IPSS), was then administered to 50 healthy men (control group), and 108 BPH patients who received medical or surgical treatment. Reliability assessment consisted of internal consistency evaluation by the Cronbach's alpha reliability test. In construct validity, factor analysis was performed using principal component analysis with Varimax rotation. Response to change of this new form was also evaluated. RESULTS: Cronbach's alpha coefficient of this scale was found to be 0.8464. Item-total correlation coefficients were between 0.3298 and 0.7886 (p < 0.0001). Factor analysis for construct validity revealed four factors. The correlation coefficients were found to be r = 0.801 (p < 0.0001) with the total IPSS, and this new QoL scale had a relatively sufficient correlation with all domains of the SF-36. Moreover, a QoL score obtained by the summation of individual grades of each item may provide valuable information just like total IPSS. The mean QoL score was 4.96 ± 9.58 and 20.28 ± 9.14 in controls and BPH patients, respectively (p < 0.0001). Moreover, QoL score significantly improved by both medical and surgical treatment. CONCLUSIONS: The new BPH-specific QoL was shown to be reliable and valid.

ErbB receptor tyrosine kinase family expression levels in urothelial bladder carcinoma.

ErbB receptor tyrosine kinases family plays an important role in cell cycle regulation. Overexpression of ErbB receptors has been described in several solid tumors. The aim of this study was to investigate the levels of ErbB1, ErbB2, ErbB3, and ErbB4 expression in bladder cancer. Urinary bladder tumor samples were obtained from 33 bladder cancers and 7 non-cancerous bladder biopsies. The levels of ErbB1, ErbB2, ErbB3, and ErbB4 genes expression in bladder cancer were determined by real-time PCR. The presence of protein was confirmed by immunostaining. Expression of ErbB1, ErbB2, ErbB3, and ErbB4 genes increased 0.67, 4.72, 2.89, and 2.65-fold, respectively, in bladder tumors as compared with normal tissue. There was a significant difference between immunostaining results of ErbB4 protein in bladder tumors and normal bladder tissue (P<0.01). The present data suggest that ErbB2, ErbB3, and ErbB4 genes may have a role in bladder cancer tumorigenesis.

Incidentally detected renal adenomatosis in a patient with urolithiasis: a case report.

A renal epithelial tumor with a papillary or tubulopapillary pattern and a low nuclear grade is defined as a renal adenoma if its diameter is 5 mm or less. Two important issues related to the renal adenoma are the lack of exact criteria for the histopathological differentiation from a papillary renal cell carcinoma and the lack of consensus as to whether it is a precancerous lesion. Renal adenomatosis is very rarely seen entity entity characterized by multiple and usually bilateral adenomas. Innumerable adenomas, adenomatous transformations within a single tubule and adenomas measuring 7 mm or less, were detected in a 47-year-old man who underwent simple nephrectomy due to nonfunctional hydronephrosis secondary to urolithiasis. In this paper, our diagnostic approach to this fairly rare entity is discussed along with a brief literature review.

SOX4 expression levels in urothelial bladder carcinoma.

High levels of SOX4 gene expression have been reported in a variety of human cancers. The protein may function in the apoptosis pathway, leading to cell death as well as to tumorigenesis. The aim of this study was to investigate the levels of SOX4 expression in bladder cancer. Urinary bladder tumor samples were obtained from 57 bladder cancer and 13 normal bladder biopsies. The levels of SOX4 expression in bladder cancer were determined by immunohistochemistry and real-time PCR. SOX4 gene expression was increased 2.2 times in bladder tumors as compared with normal tissue. The presence of protein was confirmed by immunostaining. There were significant differences between immunostaining of bladder tumors and normal bladder tissue (P=0.001). The present data suggest that SOX4 gene may have a role in bladder cancer tumorigenesis.

Reliability of frozen section examination of obturator lymph nodes and impact on lymph node dissection borders during radical cystectomy: results of a prospective multicentre study by the Turkish Society of Urooncology.

OBJECTIVE: To evaluate the accuracy of frozen section examination (FSE) for detecting lymph node (LN) metastases and whether we can use this information to decide the extent of LN dissection during cystectomy. PATIENTS AND METHODS: From August 2005 to August 2009 FSE of obturator LNs was performed in 118 patients with bladder cancer, who were undergoing radical cystectomy with extended LN dissection. Removed tissues from 12 well defined LN regions were sent separately for pathologic evaluation. The FSE results of obturator regions were compared with the final histopathologic results of these node regions. RESULTS: The mean number of removed nodes per patient was 29.4 ± 9.3 (median 28, range 12 to 51). The sensitivity, specificity, positive and negative predictive values of FSE for the 118 right obturator LN regions were 94.7%, 100%, 100% and 99%, respectively. The same values for the 118 left obturator LN regions were 86.7%, 100%, 100% and 98.1%, respectively. At final pathologic examination 28 of 118 (23.7%) patients had LN metastasis at obturator regions. Skipped metastasis was found in 15/90 patients (16.7%). Clinical and pathological stage of the primary tumour were found to be significant parameters for skipped metastasis (P = 0.008 and P < 0.001, respectively). CONCLUSIONS: Performing FSE of the obturator LNs seems to be a reliable procedure for their evaluation with acceptable negative and positive predictive values. The information obtained with FSE of obturator LNs can be used to determine intraoperatively the extent of LN dissection, especially in patients with significant comorbidity. Our study also showed that if the clinical stage of the primary tumour is < cT2, the possibility of skipped metastasis is zero.

Reliability of frozen section examination of external iliac, hypogastric, and obturator lymph nodes during radical cystectomy: a multicenter study.

OBJECTIVES: To evaluate the accuracy of frozen section examination (FSE) for detecting lymph node (LN) metastasis in patients with bladder cancer undergoing radical cystectomy and pelvic LN dissection. To our knowledge, the accuracy of FSE to identify LN metastases in patients with bladder cancer is still undetermined. METHODS: The clinical data of 360 patients who had undergone radical cystectomy with pelvic lymphadenectomy for bladder cancer in six urologic institutions were retrospectively analyzed. The nodal regions included were the external iliac, hypogastric, and obturator LNs. The FSE results of the right and left LN regions were compared with the final histopathologic results of the respective LN regions. RESULTS: The final pathologic examination revealed nodal metastases in 65 patients (18.1%). Of the 720 right and left LN regions in 360 patients, 88 (12.2%) were metastatic at the final pathologic examination. Although the FSE findings were negative, the final pathologic examination revealed LN metastases in 26 patients and in 29 pelvic LN regions. All LN regions with positive FSE findings were positive at the final pathologic examination. When we considered the 720 LN regions, the sensitivity, specificity, and positive and negative predictive values for FSE were 67%, 100%, 100%, and 95.6%, respectively. CONCLUSIONS: Until innovations in imaging methods improve nodal staging in patients with bladder cancer, performing FSE of the external iliac, hypogastric, and obturator LNs seems to be a reliable procedure for the evaluation of the LNs. The information obtained with FSE of the LNs can be used to determine intraoperatively the extent of LN dissection.

Laparoscopic excision of renal hydatid cyst in a preadolescent.

The traditional method of treating hydatid disease by open surgery has, in recent years, been challenged and minimally invasive approaches, including percutaneous and laparoscopic management, have been gaining wide acceptance. We present a 13-year-old boy with the diagnosis of isolated right renal hydatid disease, and a total pericystectomy was performed laparoscopically. Total operative time was 4.5 h and estimated blood loss was 150 ml. The only complication was an early urinary leak which was successfully treated with internal stenting. We believe further experience will reduce the operative time and complications.

Case series: pseudotumor formation in bladder as a late complication of pelvic and inguinal surgeries.

Inguinal and pelvic surgeries are rarely complicated by urologic complications. Eleven cases having such history admitted to our department with urologic symptoms were shown to have microscopic hematuria and bladder lesions as well. All of them were explored some due to retained gauze compress some due to suspected malignant formations on computerized tomography. Furthermore all were shown to be benign in nature. The cases were discussed under scope of current literature.
