Outcomes of retrograde intrarenal surgery compared with ultra-mini percutaneous nephrolithotomy in the management of renal calculi.

Introduction: To evaluate the outcomes of retrograde intrarenal surgery (RIRS) and ultra-mini percutaneous nephrolithotomy (umPCNL) in the management of renal calculi.

Material And Methods: Between March 2015 and January 2018, a total of 44 patients were treated with umPCNL. The outcomes of these patients were compared with 75 patients who underwent RIRS for renal calculi during the same time period.

Local Anesthetic Flexible Ureterorenoscopy in the Management of Urolithiasis.

Patients unfit for general anesthesia who present with renal tract pathology currently have limited options. Many of these patients present in the emergency setting with imperative reasons for intervention, including sepsis, renal failure, and pain. Conservative management and temporizing measures, such as percutaneous nephrostomy, are associated with significant morbidity.

Histological Comparison of Kidney Tissue Following Radioembolization with Yttrium-90 Resin Microspheres and Embolization with Bland Microspheres.

Background: Intra-arterial brachytherapy with yttrium-90 (Y) resin microspheres (radioembolization) is a procedure to selectively deliver high-dose radiation to tumors. The purpose of this research was to compare the radioembolic effect of Y-radioembolization versus the embolic effect of bland microspheres in the porcine kidney model.

Methods: In each of six pigs, ~25-33 % of the kidney volume was embolized with Y resin microspheres and an equivalent number of bland microspheres in the contralateral kidney.

Super selective radio embolization of the porcine kidney with 90yttrium resin microspheres: a feasibility, safety and dose ranging study.

Purpose: We determined whether super selective radio embolization of the porcine kidney was technically feasible and evaluated histopathological changes in the treatment target zone (upper or lower renal pole), adjacent nontargeted kidney, and adjacent and distant organs after administering (90)Y labeled vs bland resin microspheres.

Materials And Methods: We performed super selective radio embolization with (90)Y resin microspheres in 1 kidney and with an equivalent number of bland microspheres in the corresponding pole of the contralateral kidney as a control. The aim was to achieve radio embolization of a target zone equivalent to approximately a third of the kidney volume.

Endoscopic resection and topical 5-Fluorouracil as an alternative treatment to craniofacial resection for the management of primary intestinal-type sinonasal adenocarcinoma.

Introduction. Intestinal-type adenocarcinoma of the sinonasal tract is very rare and is responsible for less than 4% of tumours of the sinuses. Craniofacial resection has been the mainstay of treatment for many years; however, techniques for endoscopic resection are constantly being developed.
