Retrograde ureteroscopy: Experience at the Grand Yoff General Hospital in Dakar

Objective: To present the results of the ureteroscopy at the GrandYoff General Hospital (Hoggy) in Dakar (Senegal). Subjects and methods: This is a descriptive study of 91 ureteroscopy procedures performed at the Urology department of Grand Yoff General Hospital from January 2012 to December 2013. The variables of the study were indication, age, type of ureteroscopy associate or no laser, results of lithotripsy. Results: Seven diagnostic ureteroscopy and 84 therapeutic ureteroscopy were done. The average age of the patients was 44.7 years + - 13,9 years. Semi-rigid ureteroscope was used in 43 cases, flexible ureteroscope in 15 cases and rigid ureteroscope in 9 cases. The location of the stones was renal pelvis in 30 cases, upper ureter in 28 cases, distal ureter in 13 cases, calix in 10 cases and middle ureter in 3 cases. The number of laser (Nd:Yag) fragmented stones was 87. Complications were dominated by false passages in 8 cases. The overall success of endoscopic treatment was 85.7[%]. Conclusion: The current practice of endoscopic treatment for upper urinary tract stone is quite challenging to the urologist practising in sub- Sahara Africa. The effectiveness and lesser morbidity of laser lithotripsy has made it the treatment of choice for upper urinary tract stones.
