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 in digital technology and 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.  UR - http://www.transresurology.com/article_108114.html L1 - http://www.transresurology.com/article_108114_ecfcfa1dc1a7405db5f04cd2b19ac800.pdf ER -
