OBJECTIVE To the best of our knowledge there are only 3 reports of fractured guidewires inside the pelvicalyceal system, successfully removed with endourology techniques, and this is the first one presenting a tightly coiled intraparenchymal section. MATERIAL AND METHODS A 59-year-old woman was hospitalized for surgical treatment of a right kidney of reduced size. Past history revealed pyelol...

BACKGROUND Alfuzosin has been widely used to treat benign prostatic hyperplasia and prostatitis, and is claimed to be a selective agent for the lower urinary tract with low incidence of adverse side-effects and hypotensive changes. Recently, several randomized controlled trials have reported using Alfuzosin as an expulsive therapy of ureteral stones. Tamsulosin, another alpha blocker, has also ...

BACKGROUND Tamsulosin is an α-1A-specific blocker which induces selective relaxation of ureteral smooth muscle with subsequent inhibition of ureteral spasms and dilatation of the ureteral lumen and facilitates stone expelling. OBJECTIVES In this study we aimed to assess the efficacy of tamsulosin for improving the success rate of ureteroscopic lithotripsy (URS) for lower ureteral stones. PA...

BACKGROUND The purpose of this prospective study was to evaluate the feasibility of replacing intravenous urography (IVU) with unenhanced computed tomography (CT) as the first line diagnostic modality for acute renal colic in the emergency department. METHODS In the 1-year study period, 82 patients who presented themselves to the emergency room with acute renal colic and who were suspected to...

PURPOSE To investigate and compare the stone clearence and complication rates of flexible ureteroscopy (URS) with semirigid URS in patients having proximal ureteral stones. MATERIALS AND METHODS The data of 124 patients with proximal ureteral stones who underwent semirigid or flexible ureterorenoscopic lithotripsy between March 2008 and December 2012 were retrospectively investigated. The pat...

STUDY OBJECTIVE Acute renal colic is a common presenting complaint to the emergency department. Recently, medical expulsive therapy using alpha-antagonists or calcium channel blockers has been shown to augment stone passage rates of moderately sized, distal, ureteral stones. Herein is a systematic evaluation of the use of medical expulsive therapy to facilitate ureteral stone expulsion. METHO...

Introduction: The aim of this study is to compare holmium laser (LL) with pneumatic lithoclast (PL) in patients with upper ureteral stones and their ability to destruct the stones and making the patient stone free. We also compare the duration of these procedures and their complications, such as urosepsis, perforation, and pushing the stone backward. Methods: This has been a clinical randomized...

Diclofenac sodium, one of the prostaglandin synthesis inhibitors was evaluated in terms of passage or movement of ureteric stones upto the size of 0.5 cm in a series of 80 patients. Forty-six (57.5%) patients passed the stone within a period of 4 weeks. This frequency of stone passage was significantly higher when compared with stone passage of similar size in other series (P less than 0.001). ...
