A Novel Visual Grading for Ureteral Encrusted Stent Classification to Help Decide the Endourologic Treatment.

The aim of the study is to propose a visual classification for encrusted stents (ESs) to help choose the appropriate endourologic treatment. A multicenter, retrospective, and descriptive study was performed. A total of 140 patients with encrusted Double-J stents were enrolled from 5 different institutions.

Long-Term Passive Ureteral Dilatation with Double-J Stent: Possibly an Effective Treatment for Recurrent Renal Colic Caused by Papillary Renal Necrosis.

An uncommon cause of recurrent renal colic is mucous tissue passage secondary to renal papillae necrosis. Because of its low prevalence, the correct management of recurrent obstructive uropathy produced by renal papillary necrosis (RPN) is not well defined. We present a case of recurrent renal colic associated with the expulsion of mucous tissue in a young woman's urine with a history of excessive consumption of nonsteroidal anti-inflammatory drugs (NSAIDs).
