摘　　要：Introduction: The management of kidney stones has benefited from endoscopic techniques, in particular the development of flexible ureteroscopy (ureterorenoscopy). This endoscopic treatment has made it possible to treat many upper urinary tract stones, with satisfactory results and less morbidity. This innovative minimally invasive technique was introduced in our country in 2018. It is not practiced in all health structures. We report our experience. Objectives: The aim of our study was to evaluate the place of flexible ureteroscopy laser, its feasibility, and the results on stones up to 30 mm in size only in the lower calicial group, while assessing the postoperative quality of life. Patients and Methods: We conducted a monocentric observational retrospective study at the Omar Bongo Ondimba Army Training Hospital (OBO ATH) on 22 patients with symptomatic inferior caliciel stones, over a period of January 2019 and December 2020 treated by flexible ureteroscopy laser (FUR-L), once or twice depending on the size of the residual fragments. Results: All the patients had symptomatic urolithiasis, diagnosed on the clinical elements, and confirmed in 77% by urinary computed tomography. The average age was 35.47 years ± 12, with a clear female predominance (64%). All the stones sat in the lower chalice. 66.5% of stones were larger than 10 mm. 75% of patients were “stones free” after one FUR-L session, and 100% after the second session. 10% of patients still had residual pain at 01 month which was absent at 03 month. 18% of postoperative urinary tract infections were treated with antibiotics. 90% of the patients had resumed an activity prior to 1 month. At 1 month and 3 months, 82% and 100% respectively were satisfied with the mode of treatment according to self-questioning. Conclusion: FUR-L remains a therapeutic modality for stones in the lower calicial group, for stones whose diameter is close to 30 mm. A sequential approach should be considered for diameter stone up to 30 mm.Introduction: The management of kidney stones has benefited from endoscopic techniques, in particular the development of flexible ureteroscopy (ureterorenoscopy).
