This narrative collects most of them from a clinical and pathologic perspective, offering urologists and general pathologists their most salient definitory features. Together with classical, well-known, entities such as urothelial papillomas (conventional (UP) and inverted (IUP)), nephrogenic adenoma (NA), polypoid cystitis (PC), fibroepithelial polyp (FP), prostatic-type polyp (PP), verumontanum cyst (VC), xanthogranulomatous inflammation (XI), reactive changes secondary to BCG instillations (BCGitis), schistosomiasis (SC), keratinizing desquamative squamous metaplasia (KSM), post-radiation changes (PRC), vaginal-type metaplasia (VM), endocervicosis (EC)/endometriosis (EM) (müllerianosis), -

Patients are characterized by a tall eunuchoid stature, small testes, hypergonotrophic hypogonadism, gynecomastia, learning difficulties and infertility. These patients have also been found to have raised estrogen levels. We report a 16 year old boy with Kline- felter syndrome presenting to our institution with gross hematuria. Cystoscopy and biopsy revealed the diagnosis of pseudomembranous trigonitis. Immunohistochemical stains showed an increase in estrogen and progesterone receptors in the trigone area but not in the rest of the bladder. In view of the patient’s mildly raised estrogen levels and the histological findings, we postulate that estrogen is the driver of the development of pseudomembranous trigonitis. This is the first reported case of pseudomembranous trigonitis seen in association with Klinefelter syn- drome, and also the first case of pseudomembranous trigonitis occurring within the male adolescent age group.

Primary Obstructive Megaureter in a Child: a Case Report and Review of Literature
Case Report Annals of Pediatric Research Published: 10 May, 2019 Primary Obstructive Megaureter in a Child: A Case Report and Review of Literature Volkan Sarper Erikci* and Tunahan Altundag Department of Pediatric Surgery, Tepecik Training Hospital, Turkey Abstract Ureterovesical Junction Obstruction (UVJO) is a rare but important cause of hydroureteronephrosis in childhood. A 2-years-old boy suffered from giant hydroureteronephrosis originating from idiopathic ureterovesical junction obstruction. He was treated with excision of narrow ureteric segment with tapering ureteroplasty and a ureteral reimplantation was performed. This case is presented and discussed with reference to etiology of this rather rare anomaly. Keywords: Hydroureteronephrosis; Ureterovesical junction obstruction; Children Introduction Congenital Ureterovesical Junction Obstruction (UVJO) may be observed during fetal age or any stage at the time of childhood. It is aimed in this report to present a male child with obstructive megaureter due to congenital UVJO. He was surgically treated with excision of narrowed distal ureter in addition to tapering ureteroplasty with ureteroneocystostomy. The topic is discussed with special reference to the etiology of this rather rare entity under the light of relevant literature. Case Presentation A 27-months-old boy was admitted to our department with an antenatal history of right Hydroureteronephrosis (HUN). Laboratory tests were otherwise normal except signs of Urinary OPEN ACCESS Tract Infection (UTI) including leucocyturia. -

Wu, et al ACUTE NECROTIZING URETERITIS WITH OBSTRUCTIVE UROPATHY FOLLOWING INSTILLATION OF SILVER NITRATE IN CHYLURIA: A CASE REPORT Chin-Ming Su, Yung-Chin Lee, Wen-Jen Wu, Hung-Lung Ke, Yii-Her Chou, and Chun-Hsiung Huang Department of Urology, Kaohsiung Medical University, Kaohsiung, Taiwan. Chyluria occurs as a result of communication between the lymphatics and the renal pelvis. It is believed that instillation of silver nitrate into the renal pelvis is a safe, minimally invasive and effective treatment for chyluria. We report an unusual complication of acute necrotizing ureteritis following instillation of silver nitrate in a case of chyluria. It resolved completely with non-surgical intervention. The diagnosis and management of chyluria is discussed, with a brief review of the literature. Key Words: chyluria, silver nitrate instillation, necrotizing ureteritis (Kaohsiung J Med Sci 2004;20:512–5) Chyluria occurs as a result of communication between the radiation, or parasite infection were known.
