The Alpha Blockers and the Ureteral Access Sheaths Placements
The new technique of laser applications with flexible ureteroscopy and retrograde intrarenal surgery (RIRS) applications has improved a lot over the last few years. Nowadays, it is possible to effectively accomplish RIRS operations on upper urinary system stones by using devices that yield high-quality images due to developments of digital technology as well as increased deflection ability. Several modifications and suggestions are considered for its improvement. One of them is using α-blockers to boost the spontaneous passage of ureteral stones led and relaxation and to decrease intramural ureteral resistance in ureteral smooth muscles.
