OBJECTIVES: To present to report the first case of @entity1901 resolved using a new endoscopic approach, which we call microureteroscopy (m-URS) and attempts to reduce the @entity16 caused by conventional instrumentation. MATERIAL AND METHODS: We selected a 53-year-old @entity1 with a 16-mm calculus in the right distal ureter. For endoscopic access, we used a 4.8 Fr sheath from the microperc set and fragmented the stone with a 230-micron laser fiber. RESULTS: Complete fragmentation of the stone was achieved. We placed a JJ catheter due to significant @entity4 . The surgical time and postsurgical stay were 156minutes and 24hours, respectively. There were no complications, the requirements for analgesia were minimal, and the @entity1 was free of residual stones. CONCLUSIONS: The m-URS technique is feasible, simple and effective for the treatment of pelvic @entity1901 in @entity1 and optimizes minimal invasion, with results that can be comparable to conventional endoscopic techniques in terms of ease of access and @entity227 without affecting the resolution capacity. Larger studies and greater technological development is needed to define the definitive role of this procedure. Currently, its major limitations lie in the treatment of proximal @entity1698 and in the treatment of @entity1 . This technique could also be a viable alternative for pediatric @entity1 .
