Nonfunctional bladder paragangliomas may present clinical, radiology and pathological features similar to bladder cancer, so knowledge of this generally benign neuroendocrine neoplasm is of great importance to avoid misdiagnosis. We present the case of a patient with no clinical symptoms of paraganglioma and with radiological and cystoscopy examination results suggestive of urothelial carcinoma but with pathological diagnosis of paraganglioma.

The non-coding RNAs (ncRNAs) comprise a large part of human genome that mainly do not code for proteins. Although ncRNAs were first believed to be non-functional, the more investigations highlighted tthe possibility of ncRNAs in controlling vital biological processes. The length of long non-coding RNAs (lncRNAs) exceeds 200 nucleotidesand can be present in nucleus and cytoplasm.

Introduction: Surgical resection by heminephrectomy is considered the preferred treatment for duplex kidneys with non-functioning moieties. Ureteral remnant may be ligated or left in situ to avoid the risk of injury to the healthy ipsilateral ureter; however, distal redundant ureter may sometimes cause long-term complications and require further reoperation. Upper pole heminephrectomy is a surgical procedure often performed to address various renal pathologies, such as duplex kidney or non-functioning upper renal moieties.

Introduction And Importance: Ureteric stump syndrome [USS] is a series of febrile recurrent lower abdominal pain, urinary tract infections, and hematuria that sometimes present with empyema as a rare complication. The ureteric stump is left after ureteric re-implantation due to an impacted stone at the Vesical-ureteric junction [VUJ], or after nephrectomy of a non-functional kidney due to a distal stone; the ureteral stump forms a source of infection to the urinary bladder, in addition to long-term obstructive stones left at the ureteric stamp. This usually cause chronic irritation of the mucosa and potentially change to metaplasia, dysplasia and malignancy.
