This is a descriptive retro-prospective study over five (5) years from January 2015 to December 2019, conducted in the gynecology department of HDM. We had collected 100 cases of GP out of 989 surgeries, with a frequency of 9.89%. The age group of 60 years and over accounted for 33% of our patients, with a mean age of 50 years. Multiparous were the most affected (89%). The notion of obstructed labor was observed in 52% of patients. The most found reason for consultation was the feeling of lump in a vagina, with 65%. Grade III according to BADEN-WALKER classification system (BWCS) concerned 72% of our patients. Triple perineal surgery and hysterectomy involved 56% of our patients. Spinal anesthesia was performed in 96% of cases. Per and postoperative complications were dominated by urinary retention in 4% and by infection of the surgical site in 2%. The average hospital stay was 3.2 days. We recorded 88% of satisfied patients after the intervention. No deaths were recorded during the study. The management of genital prolapse remains essentially surgical;it requires a semiological analysis and a mastery of the surgical technique.展开更多
