Examination of intrarenal blood flow by Doppler ultrasound before and after extracorporeal shock wave lithotripsy for urolithiasis

Abstract

This study was aimed to test whether therapeutical extracorporeal shock wave lithotripsy (ESWL) may induce changes in renal parenchymatous blood flow, thereby indirectly indicating shock wave side effects on the renal parenchyma. In 18 patients, a Duplex ultrasound investigation of both kidneys was performed before and after ESWL. Pulsatility Index (PI), which is an estimation of renovascular resistance, increased in both treated and untreated kidney. However, the increase was confined to a subgroup of seven patients, who had received meperidine (a morphine analgetic) for analgesia. This increase is more likely to be due to a pharmacological effect of meperidine rather than a direct effect of ESWL on renal hemodynamics. In conclusion, we did not find any evidence of ESWL related affection of renal blood flow measured with duplex ultrasound, a technique sensitive enough to detect changes in renal hemodynamics due to morphine analgetics.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
