Öğe Anterior Prostatic Cyst Causing Acute Urinary Retansion in a Young Patient(Derman Medical Publ, 2016) Celik, Huseyin; Camtosun, Ahmet; Topcu, Ibrahim; Altintas, Ramazan; Tasdemir, CemalProstatic cysts are rare entities. Mostly, they originate from the posterior area of the prostate and asymptomatic. Anterior location of the prostatic cyst is rarer than posterior. The prostatic cyst in a 41 year-old man presenting with acute or nary retansion. Transurethral resection FUR) of the cyst was performed, which revealed a benign cyst lined with columnar epithelium and proliferative urothelial lining on histopathological evaluation. Prostatic cysts particularly in young men with obstructive lower urinary tract symptoms are rarely seen. Management of the prostatic cyst with TUR seems to be a minimally invasive approach with successful outcomes.Öğe Beneficial effects of nerolidol on thioacetamide-induced damage of the reproductive system in male rats(Allied Acad, 2016) Celik, Huseyin; Camtosun, Ahmet; Ciftci, Osman; Cetin, Asli; Aydin, Muhterem; Gurbuz, SukruIn this study, it was aimed to determinate beneficial effects of Nerolidol (NLR) against reproductive toxicity caused by Thioacetamide (TAA). Male, 3-4-months-old, rats (n=32) were divided into four groups. Group-1 was kept as control and given corn oil as carrier. Group-2 received TAA (200 mg/kg, intraperitoneal (i.p.), two times per week) for 3 weeks, in group-3; NRL was orally administered at the dose of 100 mg/kg per every other day by gavages, group-4; 200 mg/kg TAA and 100 mg/kg NRL were given. Thiobarbituric Acid Reactive Substances (TBARS) and reduced Glutathione (GSH) levels, Catalase (CAT), Superoxide Dismutase (SOD) and Glutathione Peroxidase (GPX), sperm parameters and reproductive organs weight were determined. TAA caused a significant rise in TBARS level and a significant reduce in GPX, CAT, SOD and GSH levels in the testicular tissues compared with the control group, while NLR led to significant reduce in lipid peroxidation via decreasing TBARS level and increasing the levels of GPX, CAT, SOD and GSH. Besides, sperm parameters significantly reduced, and pathologic testicular damage increased with TAA exposure. However, these effects of TAA on sperm parameters and histopathological changes were reversed by NLR treatment. In conclusion, our results demonstrate that the management of TAA induced the testicular damage and NLR prevented thioacetamide-induced testicular damage in rats.Öğe A Case of Cystitis Mimicking Bladder Tumor(Galenos Yayincilik, 2016) Camtosun, Ahmet; Celik, Huseyin; Altintas, Ramazan; Akpolat, NusretChronic cystitis is a usual inflammatory disease of the bladder in children. Patients typically show irritative voiding symptoms. In addition, bladder mass accumulation with the possibility of malignancy can rarely be observed. We present a 12-year-old male patient in whom radiological investigations showed a focal papillary lesion. In this paper, we aimed to discuss the management of chronic cystitis.Öğe A Case of Hydatid Cyst Mimicking Kidney Tumor(Aves, 2019) Camtosun, Ahmet; Celik, Huseyin; Yildiz, Ahmet; Altintas, Ramazan; Tasdemir, CemalA 45-year-old male patient presented with left flank pain that started a month ago. There was no history of fever or pyuria. Vital signs were normal. The rest of the systemic examination was unremarkable. There were no pathological findings on urinalysis or urine cytology. Ultrasonography revealed an 8x6.2x6 cm heterogeneous exophytic trending lesion at the lower pole of the left kidney. The lesion's walls were seen to be calcified in places, and the margin between the kidney and lesion was indistinct. It could not be differentiated by ultrasonography if the lesion is a complicated cyst or a mass. Magnetic resonance imaging scan of the upper abdomen also revealed a 9x7.5x7 cm cortical-parapelvic localized lesion at the lower pole of the left kidney, extending exophytically to the inferior. Given the possibility that the lesion is malignant, nephrectomy was planned. A laparoscopic approach was performed. Histopathological diagnosis was hydatid cyst. Enzyme-linked immunosorbent assay test for hydatid disease was negative. Albendazole 10 mg/kg twice a day was administered postoperatively for 3 weeks.Öğe Comparison of Percutaneous Nephrolithotomy Results in Pediatric Kidney Stone Disease in Patients Under the Age of 10 Years and in Patients Over the Age of 10 Years(Aves, 2016) Celik, Huseyin; Ediz, Caner; Camtosun, Ahmet; Altintas, Ramazan; Tasdemir, CemalObjective: Percutaneous nephrolithotomy (PNL) is a minimally invasive procedure that is safely performed for kidney stone surgery all over the world. In our clinic, PNL surgery was first performed in March 1998. In parallel with our increasing experience, PNL has been performed in pediatric cases. In our study, PNL operations performed in pediatric patients under the age of 10 years and in those over the age of 10 years were retrospectively investigated. Methods: Patients were between 0 and 16 years of age. They were divided into 2 groups according to age: 0-10 and 11-16 years. The PNL procedure was performed under general anesthesia with C-arm fluoroscopy in the prone position. Results: Between March 1998 and December 2014, a total of 208 pediatric urinary stone patients were operated on. The PNL procedure was performed in 210 renal units, 1 of which was performed bilaterally. In the <= 10-year-old patient group, 98 procedures (87.5%) were stone free, while clinically insignificant residual fragments (CIRFU) were found in 13 procedures (12.5%). In the > 10-year-old patient group, 88 procedures were stone free (89.79%), while clinically insignificant residual fragments were found in 9 procedures (10.2%). In the <= 10-year-old patient group, tubeless PNL was performed in 1 patient. In both groups combined, bleeding requiring transfusion occurred in just 1 case. A tract leak requiring a double J stent was detected in 1 patient in the <= 10-year-old patient group and in 2 patients in the other group. There was no other organ injury. Conclusion: PNL is a minimally invasive method and has become advantageous over open surgery because it offers higher security, particularly in experienced clinics, and procedures on pediatric patients can therefore be successfully performed.Öğe Comparison of the results of pediatric percutaneous nephrolithotomy with different sized instruments(Springer, 2017) Celik, Huseyin; Camtosun, Ahmet; Dede, Onur; Dagguli, Mansur; Altintas, Ramazan; Tasdemir, CemalWe aim to compare the outcomes, including the morbidity and success rates in children undergoing percutaneous nephrolithotomy (PCNL) using different sized devices. According to the size of instruments used during surgery, three different groups (ultra-mini-PCNL, mini-PCNL and adult size PCNL) were composed and the outcomes were compared between the groups. PCNL was applied to 225 renal units of 220 children, including 5 patients with bilateral kidney stones. Percutaneous nephrolithotomy was performed using adult instruments (24 F) in 82 renal units, using pediatric instruments (18 F) in 89 and using minimal-size instruments (9.5 F) in 50. One-hundred and twenty-four girls and 96 boys with a mean age of 8.33 (< 17) years were assessed. Stone-free rates were 78 % in group 1 (n = 39) using 9.5 F nephroscope, 75.8 % in group 2 (n = 69) using 18 F nephroscope and 71.4 % in group 3 (n = 60) using 24 F nephroscope. Time to access the collecting system, operative time, duration of nephrostomy and average postoperative hospital stay did not differ between the groups. However, mean hematocrit drop and stone burden were significantly lesser in ultra-mini-PCNL group. There was no significant difference in the complication rates between the groups, according to the modified Clavien classification system. As the important complication of PCNL, bleeding seems to be associated with diameter of dilatation, calibre of nephroscopes and stone burden. To reduce the certain complications, pediatric type of instruments is suitable but the use of adult instruments and techniques may achieve equal results.Öğe Does preoperative neutrophil-to-lymphocyte ratio have a value in predicting recurrence in bladder tumour after intravesical BCG treatment?(Scientific Publishers India, 2017) Camtosun, Ahmet; Celik, Huseyin; Altintas, Ramazan; Topcu, Ibrahim; Tasdemir, CemalThe purpose of this study was to evaluate the prognostic value of the ratio of preoperative neutrophil to lymphocyte after intravesical BCG treatment in non-muscle invasive bladder cancer (NMIBC). The data of 89 patients, operated for urothelial carcinoma and treated with BCG after the diagnosis of NMIBC between 2007 and 2014, were reviewed retrospectively. Preoperative complete blood counts and first cystoscopic examination findings of the patients were examined. Median follow-up was 28.7 months. Tumour recurrence was detected in 33 patients (Group 2) of 89 patients. There was no tumour recurrence in 56 patients (Group 1). Neutrophil/lymphocyte ratio, MPV and CIS incidence were significantly increased in Group 2. This study showed that, preoperative high neutrophil/lymphocyte ratio, MPV and CIS occurrence can be used as independent criteria to predict tumour recurrence after intravesical BCG treatment in NMIBC.Öğe Frequency of Stent Placement after Ureteroscopic Lithotripsy in a University and a State Hospital(Dicle Tıp Dergisi, 2016) Çelik, Hüseyin; Camtosun, Ahmet; Ediz, Caner; Topcu, İbrahim; Altıntaş, Ramazan; Taşdemir, CemalÖz: Amaç: Çalışmanın amacı, taş hastalığının endemik ol- duğu ve sık üreterorenoskopi yapılan iki farklı şehirdeki üniversite hastanesi ve devlet hastanesinde yapılan üre- terorenoskopik litotripsi sonrası üreteral stent yerleştirme sıklığının karşılaştırılmasıdır. Yöntemler: İki bin on dört Ocak ayı ile 2014 Mayıs ta- rihleri arasında İnönü üniveritesi Turgut Özal Tıp Merkezi Hastanesi (TÖTM) ve Osmaniye Devlet Hastanesi (ODH) üroloji kliniklerine başvuran hastalar retrospektif olarak değerlendirildi. Üreteral taşa bağlı olarak üreteroskopik litotripsi yapılan hastalar taş lokalizasyonu, boyutu, ektazi dereceleri ve stent yerleştirilme durumuna göre değerlen- dirildi. Bulgular: Her iki hastaneden 92 şer hasta çalışmaya alındı. Endoskopik üreteral taş tedavisi sonrası TÖTM de 85 ve ODH de 82 hastaya DJ stent yerleştirildi. Üniversite hastanesinde stent yerleştirilme sıklığı devlet hastanesin- de yüksek çıksa da istatiksel anlamlılık yoktu. Her iki grup arasında ortalama operasyon süreleri arasında istatiksel anlamlılık vardı. Sonuç: Endoskopik üreter taşı tedavisi sonrası DJ stent yerleştirilmesi çok sık uygulanmaktadır. Bizim çalışma- mıza göre üniversite hastanelerinde devlet hastanelerine göre daha sık DJ stent yerleştirilmesi yapılmaktadır. Bu- nun nedeni üniversite hastanelerinin son basamak mer- kezler olmasından dolayı daha komplike hastaların bu merkezlere refere edilmesi olabilir. Bu durumun daha net aydınlatılabilmesi için, prospektif, çok merkezli ve daha geniş serili çalışmalara ihtiyaç duyulmaktadırÖğe Neonatal testicular torsion suggesting diagnosis of testicular tumour in a newborn infant(Turgut Özal Tıp Merkezi Dergisi, 2016) Çelik, Hüseyin; Camtosun, Ahmet; Altıntaş, Ramazan; Taşdemir, CemalScrotal swelling in infants is a nonspecific sign of a wide range of pathologies, from benign diseases to malignancies and acute surgical emergencies such as testicular torsion and tumors. We present here a case with testicular mass shown in ultrasonography examination and high level of AFP were found shortly after birth in another hospital and was referred to our clinic as a case with the suspicion of testicular tumor. Within 4 hours, the infant underwent scrotal exploration. Delayed testis torsion was detected and orchiectomy was performed. Histopathology of the specimen revealed hemorrhagic infarction and necrosis. Scrotal USG can nearly always be used to confirm a testicular mass, whereas a differentiation between torsion and tumor can more accurately be done by Colour Doppler USG. An emergency exploration must be performed in the treatment of both diseases.

The incidence of urolithiasis among pediatric age groups varies according to region and is high in Turkey. The management of stone disease in children has improved dramatically over the last two decades. The high success rate of percutaneous nephrolithotomy (PNL) have led modern researchers to suggest that it be used as a first-line treatment of kidney stones greater than 2 cm in size. This study compared the outcomes, including morbidity and success rates, of different groups of pediatric patients who underwent PNL via pediatric-and adult-sized instruments. Methods Percutaneous nephrolithotomy was performed in 194 children in a clinical setting between the years 2000 and 2015. Patients were categorized into 2 groups (group 1: pediatric-sized devices used, n = 90 [46.4%]; group 2: adult-sized devices used, n = 104 [53.6%]). The children in group 2 were further divided into subgroups: a 24 F nephroscope was used for group 2a (n=84 [43.3%]) and a 26 F nephroscope was used for group 2b (n = 20 [10.3%]) (Figure). Results For this study, a total of 194 pediatric patients (99 boys and 95 girls ranging from 8 months to 17 years of age, with a mean age of 9.43 years) underwent PNL for the removal of kidney stones in a clinical setting. Between the examined groups, there were no significant differences in patient height or weight, stone site or localization, pre-and post-operative creatinine levels, duration of nephrostomy, or hospitalization time. There was also no significant variation in minor complications such as fever or urinary infection. However, the stone burden was notably smaller in the group wherein pediatric-sized nephroscopes were used. Additionally, the incidence of hemorrhage was markedly lower in groups where a 17 F nephroscope was used than in groups where treatment was administered via 24 and 26 F nephroscopes. Conclusions Stone disease is considered to be relatively rare in childhood, but recent studies have indicated that it presents a considerable health problem. According to some researchers, a decrease in instrument size has not meaningfully reduced complication rates. In contrast, some studies have reported that the use of smaller sized nephroscopes may reduce rates of morbidity and mortality. In this study, success rates of PNL were similar across all groups, regardless of nephroscope size. However, the use of a 17 F nephroscope significantly decreased the rate of hematocrit level reduction (p < 0.001). While instrument size does not affect the success of PNL, smaller instruments can be used to reduce various complications such as bleeding.Öğe Renal Primitive Neuroectodermal Tumor(Galenos Yayincilik, 2017) Celik, Huseyin; Camtosun, Ahmet; Dursun, Ibrahim; Akpolat, Nusret; Yildirim, Ismail OkanRenal primitive neuroectodermal tumor ( PNET) is a rare entity and highly malignant neoplasm. It generally occurs in young adults and children. We report a case of 19-year-old female with the complaint of left flank pain. Ultrasonography showed a tumor of the left kidney. A big left inhomogeneous renal mass of 10x8 cm with areas of necrosis was observed on computed tomography. The patient underwent radical nephrectomy with lymphadenectomy. Immunohistochemical stains were positive for CD99 and FL-1. Immunohistochemical and microscopic results were compatible with PNET. Furthermore, the patient received eight cycles of chemotherapy, and was still alive without metastases at 6-month followup. Renal PNET is a rare and poor prognosis tumor. It is sometimes difficult to discriminate between PNET and Ewing's sarcoma. Renal PNET must be included in the differential diagnosis of renal tumors particularly in young adults and children. With this case report it aimed to create awareness about PNET.
