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...

BACKGROUND This research aims to evaluate the role of tamsulosin in the medical expulsion therapy for distal ureteral stones, including her effects in stone expulsion time, expulsion rates, stone size, pain episodes and analgesic dosage usage. MATERIAL AND METHODS The 104 patients with distal ureteral calculi were examined, with the size of the stones 4-10 mm. They were randomly divided into ...

Objective: To evaluate the efficacy of ambulatory extracorporeal shock wave lithotripsy monotherapy in the treatment of staghorn calculi. Materials and Methods: Using piezoelectric lithotriptors (EDAP-LT01 or LT02), 268 staghorn calculi were treated. One hundred and forty three were complete and 125 were partial (65 filled the renal pelvis + one calyceal system, and 60 filled the renal pelvis +...

Ureteric calculi are common urological problems. However, the management of stone disease varies considerably with patient choice and anatomy. There few reports about ureteral in patients unilateral complete duplex kidneys managed by ureteroscopy. We hope to increase awareness urologists when investigating similar symptoms. present case a 28-year-old man recurring left flank pain. Non-contrast ...

PURPOSE Typically in Korea, for a standard dose (0.4 mg) of tamsulosin, two low doses (0.2 mg) are administered. The aim of this study was to evaluate and compare the efficacy of tamsulosin (0.2 mg and 0.4 mg) and alfuzosin (10 mg) in the treatment of lower ureteral stones. MATERIALS AND METHODS A total of 141 patients presenting with a single 4- to 10-mm sized lower ureteral stone were rando...

BACKGROUND Acute pyelonephritis (APN) is a common complication of ureteral obstruction caused by urolithiasis, and it can be lethal if it progresses to septic shock. We investigated the clinical characteristics of patients undergoing emergency drainage and assessed risk factors for septic shock. METHODS A retrospective study was performed of 98 patients (101 events) requiring emergency draina...

PURPOSE To determine the efficiency of slow delivery rate of shockwaves (SW) on stone fragmentation and treatment outcomes in patients with renal and ureteral calculi. PATIENTS AND METHOD Using the Siemens Lithostar Multiline, we treated 843 patients (229 renal and 614 ureteral stones) at a fast delivery rate (120 SW/min, between October 2003 and August 2006), 448 patients (139 renal and 309 ...

The use of dual-energy computed tomography (DECT) for evaluating urinary calculi has been appreciated due to the modality's capability of differentiating between uric acid (UA) and non-UA stones, which are color coded based on a postprocessing algorithm. No other imaging modality or laboratory test is able to identify the stone composition without first attaining the stone material. Knowledge o...

A wide variety of calcifications may develop in the urinary tract. Calculi, the most common form of urinary tract calcification, are usually radiopaque due to their calcium content, whereas cystine stones tend to be less opaque. In cortical nephrocalcinosis, calcification may be spotty or may appear as a thin rim outlining the cortex. Intracystic calcification is usually thin and peripheral and...
