Study of ureteral and renal morphometry on the outcome of ureterorenoscopic lithotripsy: The critical role of maximum ureteral wall thickness at the site of ureteral stone impaction.

Purpose: The purpose is to study the association of stone, ureteral, and renal morphometric parameters with the relevant outcome variables, i.e., complication rate, stone-free rate (SFR), and operating time of ureterorenoscopic lithotripsy.

Bellini Duct Carcinoma: A Rare Entity.

Bellini duct carcinoma of kidney derives from collecting duct and is associated with an aggressive course and extremely poor prognosis. Here, we report an interesting case of Collecting Duct Carcinoma (CDC) with Inferior Vena Cava (IVC) thrombus and large retroperitoneal lymph nodes and diffuse desmoplastic reaction. The patient underwent left open radical nephrectomy with IVC thrombectomy and regional lymphadenectomy.
