Minimally Invasive Surgery for the Treatment of Ureteric Stones - State-of-the-Art Review.

Res Rep Urol 2021 6;13:227-236. Epub 2021 May 6.

Department of Urology, University Hospital Southampton NHS Trust, Southampton, UK.

The landscape of managing ureteric stones has evolved over the last few decades and several treatment options exist depending on the stone size, location, and other patient and stone factors. While open surgery is now rarely performed, the use of medical expulsive therapy (MET) has been controversial and perhaps only recommended for large distal ureteric stones. The mainstay treatment balances between shockwave lithotripsy (SWL) and ureteroscopy (URS), with the latter usually recommended for larger stones. Read More
