Purpose. We aimed to compare and evaluate the outcomes and complications of two endoscopic treatment procedures, semirigid ureteroscopy (SR-URS) and flexible ureteroscopy (F-URS), in the treatment of proximal ureteral stones (PUS). Methods. SR-URS (group 1) was done on 68 patients whereas 64 patients underwent F-URS (group 2) for the treatment of PUS. Success rate was defined as the absence of ...

Urolithiasis is a significant and worldwide health problem. Ureteral stones account for approximately 20% of urolithiasis cases. 70% of those cases are with location of stone in the distal 1/3 rd of ureter hence known as Distal Ureteral Stones (DUS) or Lower Ureteral Stones (LUS). Recently certain drugs have been used as supplement for observation in an effort to improve spontaneous stone expul...

Background: Protease inhibitors (PIs) are a well-documented cause of nephrolithiasis. Although medications such as indinavir are known to increase risk of stone formation, the association of newer HIV medications is not as well studied. In this study, we report a case of a patient who developed atazanavir stones. Case Presentation: A 74-year-old man with HIV on antiretroviral therapy-including ...

BACKGROUND Animal studies have shown that nicotine affects the peristalsis of the ureter. The aim of the study is to analyze the effect of smoking on spontaneous passage of distal ureteral stones. METHODS 88 patients in whom distal ureteral stone below 10 mm diameter diagnosed with helical computerized tomography enhanced images were reviewed. Patients were grouped as either smokers (n:33) or...

OBJECTIVES To compare 4 ureteral occlusion devices in terms of insertion force, maneuverability, radial dilation and extraction forces, ability to prevent stone migration, and tip stiffness. METHODS The devices tested were the PercSys Accordion, Microvasive Stone Cone (7 and 10 mm), and Cook N-Trap. Using a ureteral model with an artificial stone in place, the insertion force, number of attem...

PURPOSE This retrospective study evaluated the unenhanced multi-detector computed tomography (MDCT) findings of urinary system calculi and the secondary signs associated with ureteral stones in children. MATERIALS AND METHODS The study included 87 children (54 boys, 32 girls) with a mean age of 89 months (range: 5 months to 16 years) who were referred to us from various departments and were e...

Objectives. We compared outcome and complications after uncomplicated ureteroscopic treatment of distal ureteral calculi with or without the use of ureteral stents. Materials and Methods. 117 patients, prospectively divided into three groups to receive a double j stent (group 1, 42 patients), ureteral stent (group 2, 37 patients), or no stent (group 3, 38 patients), underwent ureteroscopic trea...

Treatment of ureteral calculi has dramatically changed over time. Open surgery was the method of choice before the 80s, however, two events strongly influenced the management of ureteral lithiasis: the development of rigid ureteroscopy and the application of shock waves. Since then, many papers have been published to assess the efficacy of each technique. They take into account several endpoint...

OBJECTIVE We aimed to evaluate the factors influencing treatment option selection among urologists for patients with ureteral stones, according to the stone diameter and location. METHODS We retrospectively reviewed the records of 360 consecutive patients who, between January 2009 and June 2014, presented to the emergency department with renal colic and were eventually diagnosed with urinary ...
