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...

PURPOSE To evaluate one aspect of tipless and helical stone basket function that is critical for ureteral stone extraction: the radial-dilation force. MATERIALS AND METHODS Nine commercially available tipless baskets and five commercially available helical stone baskets were tested. Two Teflon blocks were positioned with the lower block sitting on a digital scale and the upper block secured t...

Background: Medical Expulsive Therapy (MET) has become an established part of the protocol for treatment of ureteric stones of less than 5 mm size in the lower 1/3rd of the ureter. Drugs like calcium channel blockers and α-1 adrenergic blockers with or without corticosteroid along with hydration have been used to facilitate expulsion of stones. Aims & Objective: In this study effectiveness of α...

Context: Medical expulsive therapy (MET) augments expulsion rates and reduces colic events. Therefore, MET is an appropriate procedure to facilitate stone passage during the observation period in patients who have a newly diagnosed ureteral stone and whose symptoms are controlled. Increasing evidence indicates that supportive therapy following shock wave lithotripsy (SWL) for urolithiasis is al...

A single-board certified urologist with training and experience in anesthesiology was assigned to treat 502 patients (185 with renal stones, 317 with ureteral stones) using the Dornier Compact Delta lithotripter under general or epidural anesthesia. Data were obtained regarding stone location, stone size, shockwave use, stone-free rate, and complications. In all, 502 stones were treated with th...

INTRODUCTION AND OBJECTIVES Ectopic pelvic kidneys with renal stones are challenging to treat. We report our experience in managing a case of ectopic pelvic kidney with a pelvic stone by robotic pyelolithotomy after failure of flexible ureteroscopy. MATERIALS AND METHODS A 46-year old male with 2 months history of vague lower abdominal pain was found to have on Computed Tomography scan a left...

Objective: The objective of study was to determine the efficacy of Tamsulosin (alpha blocker) in spontaneous expulsion of 4-7mm ureteric stones in the distal segment of the ureter. Subjects and methods: This randomized controlled trial study was conducted in the department of Urology, Shaikh Zayed Hospital between 24 th November, 2008 to 24 th May, 2009. A total 90 patients with lower ureteric ...

PURPOSE For treating proximal ureteral calculi, treatment decision has been known still difficult to choose ureteroscopic lithotripsy (URS) or shockwave lithotripsy. The aims of our study are to identify the possible predictors for necessity of URS and to propose the Gachon University Ureteral Narrowing scoring system (GUUN score) as a helpful predictor. MATERIALS AND METHODS We evaluated 83 ...

OBJECTIVE To evaluate the factors affecting success of semi-rigid ureteroscopy in proximal ureter stones. STUDY DESIGN Descriptive study. PLACE AND DURATION OF Department Urology, Nevsehir State Hospital, Turkey between March 2017 and October 2019. METHODOLOGY Patients, who underwent a ureteroscopic lithotripsy (URSL) operation for ureteral stones, were evaluated retrospectively terms gender, a...
