摘　　要：<strong>Aim:</strong> To evaluate the efficacy and safety of intraluminal lithotripsy with a pneumatic lithotripter (EMS, Switzerland) and laser Holmium YAG in retrograde rigid ureteroscopy for proximal and distal ureteric calculi. <strong>Materials and Methods:</strong> This was a retrospective study carried out from January 2015 to December 2019 including 175 patients with ureteric calculi who presented with ureteric colic at a mini-invasive surgical urological center in Douala, Cameroon. All the patients underwent retrograde ureteroscopy with a 7F rigid ureteroscope, and fragmentation was done with either a pneumatic lithotripter or a laser holmium YAG. Six patients who had urinary tract infection benefited from double J stent placement before retrograde ureteroscopy. The study variables included age, clinical symptoms, size and location of the stone, the type of lithotripsy, operating time, and the results of lithotripsy. <strong>Results:</strong> We included a total of 175 patients with a mean age of 40.95 ± 12.50 years. Seventy-six (43.43%) of our participants were females and all patients had at least one calculus confirmed by a CT scan. Stone sizes ranged from 5 - 26 mm (median of 12 mm). Fifteen (8.57%) stones were located in the upper ureter (pyeloureteric junction), 64 in the middle ureter, 20 in the iliac ureter, 43 in the pelvic ureter, and 33 at the vesico-ureteric orifice. The success rate was 100% for stones located in the iliac ureter, pelvic ureter and the ureteric orifice. For those in the middle and upper ureter, the success rate was 92.18% and 60%, respectively. <strong>Conclusion:</strong> Rigid ureteroscopy is an excellent treatment modality for ureteral calculi, especially those located at the distal part of the ureter. The procedure is associated with a shorter operation time and a shorter post-operative hospitalization period, in addition to its safety and effectiveness compared to open surgery.<strong>Aim:</strong> To evaluate the efficacy and safety of intraluminal lithotripsy with a pneumatic lithotripter (EMS, Switzerland) and laser Holmium YAG in retrograde rigid ureteroscopy for proximal and distal ureteric calculi. <strong>Materials and Methods:</strong> This was a retrospective study carried out from January 2015 to December 2019 including 175 patients with ureteric calculi who presented with ureteric colic at a mini-invasive surgical urological center in Douala, Cameroon.
