BACKGROUND: Rates of administration of intravenous sodium fluorescein during cystoscopy have increased since indigotindisulfonate sodium was removed from the market in 2014. Although sodium fluorescein has been extensively evaluated and found to be safe, side effects including anaphylaxis have been observed, with an incidence between 0.05% and 1.0%. CASE: We present a case of anaphylactic shock after administration of intravenous sodium fluorescein for the assessment of ureteral efflux in a patient with a history of frequent severe allergic reactions undergoing urethral lysis and cystoscopy for urinary retention...

Urinary tract involvement by endometriosis is reported in 1% of endometriosis patients (NP3). Consequences range from pelvic pain for bladder localizations to silent kidney loss in case of chronic ureteral obstruction (NP3). The feasibility of laparoscopic management was widely proven (NP3) and may reduce hospital stay length (NP4). Radical surgery with partial cystectomy for bladder localizations was shown to significantly and durably reduce pain symptoms with low risk of a severe postoperative complications (NP3)...

INTRODUCTION: Ureterocele is a cystic dilatation of the lower part of the ureter. It is a congenital anomaly that is associated with other anomalies such as a duplicated system, and other diseases. It poses a great challenge owing to its numerous types and clinical presentations. Its incidence is 1 in every 4000 individuals. One of its presentations in the adult population is the presence of a stone, usually a solitary stone, inside the ureterocele. CASE PRESENTATION: We are reporting a case of an adult ureterocele complicated by a large calculus; managed endoscopically with transurethral deroofing of the ureterocele followed by cystolitholapaxy...

OBJECTIVES: The most important treatment strategy for obstructive nephropathy is to protect renal tissue from the deleterious effects of fibrosis. Therefore, we sought to investigate the renoprotective effects of darbepoetin alfa on unilateral ureteral obstructions. METHODS: We used 12 female and 12 male 3-monthold Wistar rats weighing between 250 and 350 g. The rats were divided equally into sham, darbepoetin and control groups. With the exception of the sham group, left unilateral obstructions were applied to all of the rats...

Sphingosine Kinase-2 (Sphk2) is responsible for the production of the bioactive lipid Sphingosine-1 Phosphate, a key regulator of tissue repair. Here we address the in vivo significance of Sphingosine Kinase -2 in renal inflammation/fibrosis in response to unilateral ureteral obstruction using both genetic and pharmacological strategies. Obstructed kidneys of Sphk2-/- mice showed reduced renal damage and diminished levels of the renal injury markers TGFβ1 and αSMA when compared to wild type controls. We found a consistently significant increase in anti-inflammatory (M2) macrophages in obstructed Sphk2-/- kidneys by flow cytometry and a decrease in mRNA levels of the inflammatory cytokines, MCP1, TNFα, CXCL1 and ILβ1, suggesting an anti-inflammatory bias in the absence of Sphk2...
