[Stone burden on extracorporeal shock wave lithotripsy].
Based on the 89 stones treated by ESWL therapy alone, the factors which influence the number of ESWL shots were analyzed. Stone volume was calculated by summing up the value "length x short axis" for each stone. The value correlated well with the number of shots needed to disintegrate the stone (p less than 0.01). The stones below the pelvis-ureteral junction needed twice shots compared with st...
متن کاملImpact of Pretreatment Hydronephrosis on the Success Rate of Shock Wave Lithotripsy in Patients with Ureteral Stone
PURPOSE To evaluate predictors of the success rate for one session of shock wave lithotripsy (SWL), focusing on the relationships between pretreatment hydronephrosis grade and one-session SWL success rates. MATERIALS AND METHODS The medical records of 1824 consecutive patients who underwent an initial session of SWL for treatment of urinary stones between 2005 and 2013 were reviewed. After ex...
متن کاملLife-Threatening Complication after Extracorporeal Shock Wave Lithotripsy for a Renal Stone: A Hepatic Subcapsular Hematoma
Extracorporeal shock wave lithotripsy (ESWL) has revolutionized the management of urolithiasis since it was first introduced in 1980. ESWL is a well-established, safe and effective therapeutic alternative to surgical treatment for urolithiasis. Complications of ESWL do occur in a small number of patients, and when they do, they typically involve the kidney. We present a case of a young female p...
متن کاملStone Attenuation Value and Cross-Sectional Area on Computed Tomography Predict the Success of Shock Wave Lithotripsy
PURPOSE To identify the parameters on noncontrast computed tomography (NCCT) that best predict the success of shock wave lithotripsy (SWL). MATERIALS AND METHODS We reviewed the records of 75 patients who underwent SWL for urinary calculi measuring 5 to 20 mm. Using NCCT images, we estimated the largest stone cross-sectional area and contoured the inner edge of the stone. Clinical outcome was...
متن کاملThe success of extracorporeal shock-wave lithotripsy based on the stone-attenuation value from non-contrast computed tomography
OBJECTIVE To determine the utility of the urinary stone-attenuation value (SAV, in Hounsfield units, HU) from non-contrast computed tomography (NCCT) for predicting the success of extracorporeal shock-wave lithotripsy (ESWL). PATIENTS AND METHODS The study included 305 patients with renal calculi of ⩽30 mm and upper ureteric calculi of ⩽20 mm. The SAV was measured using NCCT. Numerical variab...
