Abstract

A total of 149 patients with 152 ureteral stones were treated with intraureteral lithotripsy by Dye-laser (83.55%), Alexandrite-laser (41.27%), electrohydraulic lithotripsy adapted for use in the ureter (25.16%) or neodymium: YAG laser with optomechanic coupling (3.2%). The Dye-laser has an automatic pulse shut-off mechanism with spectral analysis of the reflected laser beam, so that effective laser pulses can only be released by contact with a stone. Most (127 of 83.5%) of the stones could be completely fragmented, so that no further treatment was necessary. In 16 cases (10.5%) the stone was too hard for fragmentation and had to be removed by alternative techniques. Intraureteral lithotripsy is a save and effective method of treating ureteral stones that cannot be reached or have not been treated successfully by shockwave lithotripsy. No significant differences in outcome were found between the different lasers or electrohydraulic lithotripsy. In selected cases endoscopic treatment may be recommended as treatment of first choice.

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.
