Introduction: The management of urinary lithiasis in our settings has long been conventional surgery. The recent introduction of endoscopy of the upper urinary tract represents a major advance in our department. The aim was to contribute to the study of the treatment of lithiasis of the upper urinary tract in Conakry and to report on our initial experience of ureteroscopy in Conakry. Methodology: This is a prospective descriptive study lasting one year, from January 1 to December 31, 2022, carried out at the Urology Department of the Ignace Deen National Hospital and at the PERCHIN Urological Clinic. The study included all patients treated surgically for lithiasis of the upper urinary tract who met the selection criteria. Results: The study included 57 patients. The mean age was 30 years, with extremes of 20 and 73 years;the most represented age group was 31 to 40 years, followed by 20 to 30 years with 29.9% and 26.3% respectively. Males predominated in 36 cases (63.15%), with a M/F sex ratio of 1.71. Left-sided renal colic was the most common, at 75.43% (n=43), and right-sided renal colic at 40.35%, associated with digestive signs at 43.85%. 77.19% had normal creatinine levels before surgery, versus 22.81% with elevated creatinine levels, i.e. 15.78% improvement in renal function after surgery. Urinary tract infection was found in 47.36%, and Escherichia coli in 31.57%, followed by staphylococcus aureus in 8.77%. Overall, 82.45% of patients had organic damage to the kidneys or ureters. Right ureterohydronephrosis was noted in 56.14%, followed by left hydronephrosis in 26.32%. Open surgery was predominant in 52.63% of cases, with endoscopic surgery (URS) accounting for a significant 47.36% during the study period. The endoscopic treatment used was laser ureteroscopy. In our study, 73.68% underwent drainage of the upper excretory tract, including 64.91% with a JJ catheter. The average length of stay was 07 days, with extremes of 02 and 28 days, and 81.4% of patients who underwent URS had a length of stay of less than 4 days. Conventional surgery had the highest complication rate (14.28%). The stone free rate for the two surgical treatment methods (open and endoscopic surgery) was 73% and 92.59%.
