    A Rare Complication of Brucellosis: Testicular Abscess
    (2015) Gul, Umit; Demiroglu, Yusuf Ziya; Erbay, Gurcan; Kocer, Nazim Emrah
    Brucellosis is a zoonosis caused by Brucella species. Brucella epididymo-orchitis had been reported in up to 20% of patients with brucellosis. This case was a male patient who developed Brucella epidiymo-orchitis and testicular abscess. He had fever, arthralgia and his right epididymis and right testicle were enlarged and tender. Ultrasound evaluation showed hypertrophy of the right epididymis and testis and moreover hypoechoic area within the testis. Brucella serology was positive and the patient did not respond completely to treatment with streptomycin, doxycycline, and rifampicina. Unilateral orchidectomy was decided. In areas where brucella infection is endemic brucella epididymo-orchitis should be considered in the differential diagnosis. Effective and rapid treatment is important. It should be noted that these patients may develop testicular abscess.

    The Diagnosis and Treatment of Retroperitoneal Mass
    (2015) Gul, Umit
    Retroperitoneal masses are extremely rare. They may be primary malignant, benign or metastatic. The majority of them are malignant. Possible causes that may reveal the etiology of these masses have not been clarified yet. However some predisposing factors have been identified. These masses are classified according to their histological types. Clinical signs are presence of abdominal mass and abdominal pain. A multidisciplinary approach for diagnosis and treatment in high-volume referral centers is ideal. Retroperitoneal masses are treated surgically as much as possible. It is important to achieve negative surgical margins. Optimal treatment approaches have not been standardized as of today. Anthracycline chemotherapy which may be combined with radiotherapy forms the basis of therapy. Developments related to targeted therapies are particularly promising.

    Risk Factors for Urothelial Cancers
    (2016) Kuzgunbay, Baris; Gul, Umit; 0000-0003-3249-0895; AAK-8394-2021
    Urothelial cancers affect renal pelvis and ureters in the upper urinary tract, however they affect bladder and urethra in the lower urinary tract. The rate of the urothelial carcinoma makes up 3% pf cancers in the world. Although urothelial cancer locations and frequencies show difference, their etiology are similar. Environmental factors are responsible for most urothelial cancer cases. Major risk factors are smoking and chemical carcinogens. Other important factors include radiotherapy, alcohol, coffee consumption, artificial sweeteners, arsenic exposure, schistomiasis, cronical cystitis, urolithiasis, analgesics, cyclophosphamide and genetic predisposition. Identification of these factors and avoiding them are important for the prevention of the disease. The evaluation and follow up of the whole urothelium is critical since the urothelial cancers are a kind of panurethelial diseases.

    Isolated Tuberculous Epididymoorchitis Developing After Allogeneic Haematopoietic Stem Cell Transplantation: A Case Report
    (2017) Yeral, Mahmut; Demiroglu, Yusuf Ziya; Gul, Umit; Aytan, Pelin; 0000-0002-2553-7715; 0000-0003-3249-0895; 0000-0002-9866-2197; AAE-3833-2019; AAK-8394-2021; AAZ-9711-2021; ABC-4148-2020
    We report a case of isolated tuberculous epididymoorchitis developing in a patient after haematopoietic stem cell transplantation (HSCT). Forty-four-year-old male was admitted to the hospital with scrotal pain and swelling 6 months after an allogeneic HSCT using a fullymatched sibling donor because of his acute myeloid leukemia. There were scrotal tenderness, thickening and erythema on the right side. Brucella standard tube agglutination test was negative. Increased scrotal skin thickening, edema in the right epididymis and increased testicular vascularization were detected on ultrasonography. He was readmitted to our hospital with recurrent scrotal pain after 3 months of partial improvement with oral ciprofloxacin administered for a diagnosis of right epididymoorchitis. Pelvic magnetic resonance imaging revealed bilateral epididymoorchitis and scrotal abscess. Acid fast bacilli were detected on Ehrlich-Ziehl-Neelsen staining of the content of abscesses drained under local anesthesia. Mycobacterium tuberculosis complex was isolated on the 24th day of quadruple anti-tuberculosis therapy. Scrotal fistula developed on the first month of therapy which healed spontaneously after discontinuation of immunosuppressive agents. Full recovery was achieved after six months of antituberculosis therapy. As a result, tuberculous epididymoorchitis should be kept in mind in the presence of chronic epididymoorchitis developing in patients receiving immunosuppressive therapy.
