title: [Exploration of the intra-renal collecting system using flexible fibroscopy].
abstract: 23 cases of flexible retrograde nephroscopy system for undiagnosed hematuria or filling defect are reviewed. The introduction was carried out by combining hydraulic dilation, rigid ureterorenoscopy and a working sheath. The indications were merely diagnostic (filling defects and/or haematuria). The success rate was very high (22 of 23). 9 cases of papillary tumors, 4 cases of small radiolucent stones and 1 case of papillary necrosis were diagnosed. In 8 cases no pathology was found. The complication rate was extremely low and the postoperative course was uneventful. Flexible instruments offer a very good chance to explore the intrarenal collecting system and transureteral nephroscopy through a 10.8 F flexible scope is a feasible and effective procedure.
