Abstract
The treatment of urinary stones uses a varied therapeutic arsenal. Nowadays the mini-invasive techniques are the most used. We report our first experience on the results of flexible and semi-rigid ureteroscopy in the treatment of the upper urinary tract stones. Materials and Methods: A 20-month prospective study on flexible laser ureteroscopy was conducted at the Saint Camille Hospital of Ouagadougou. The inclusion criteria were for patients who had given informed consent and the presence of an unilateral obstructive upper urinary tract stone with an indication of surgical management. Results: 54 patients were treated with Holmium laser photo vaporization between January 2018 and August 2019. The average age of patients was 37.74 ± 17 years (11 - 83 years). The men were predominant at 55.56%, or a sex-ratio of 1.25. The average size of stones of 17.55 mm ± 4.16 mm (11 mm to 25 mm) with pyelic, ureteral and calyceal localization in respectively 42.6%, 33.3% and 24.1% of cases. The average duration of the interventions was 77.92 ± 43.57 minutes (11 to 180 minutes). We used drainage in 90.91% of the cases. The average duration of hospitalization was 1.2 ± 0.73 days with extremes ranging from one day to 6 days. The vaporization without residual fragment which is a success was 78.46%. Conclusion: Laser ureteroscopy is a newly used method at the Saint Camille hospital. The achievement of good results and its low morbidity encourage us to promote its extension and its use in sub-Saharan African hospitals.
Highlights
Urinary lithiasis is the presence in the urinary tract of crystalline, mineral, organic or medical concretions [1].The urinary lithiasis, a highly recurrent pathology, is responsible for several hospitalizations in urology services and can be responsible for many renal functional consequences [2] [3].The prevalence in western countries is estimated at around 10% [1]

Summary
Urinary lithiasis is the presence in the urinary tract (renal cavities, ureters, bladder) of crystalline, mineral, organic or medical concretions [1]. The prevalence in western countries is estimated at around 10% [1]. In Burkina Faso, the hospital prevalence of urinary lithiasis was 12.52% [5]. In the treatment of upper urinary tract stones, Laser Ureteroscopy is an effective and safe method. The therapeutic choice of upper urinary tract stones depends on the location and size of the stones. Laser Ureteroscopy appears to be the appropriate treatment for stones less than 20 mm [6]. Its low morbidity urges some urologists to prefer several sessions of the Laser Ureteroscopy to a Percutaneous Nephrolithotomy when the size of stones exceeds 20 mm [7]. We report our first experience on the results of flexible and semi-rigid ureteroscopy in the treatment of the upper urinary tract stones
