Aims: The aim of this study was to evaluate the postoperative complications using a standardized classification; modified Clavien's classification. Patients and methods: We have included all patients aged at least 50-years-old on the day of surgery between the 1 st June 2015 and 31 st May 2017 at the urology division of Souro Sanou University Teaching Hospital of Bobo-Dioulasso. Complications reports were performed according to the modified Clavien-Dindo system. Results: Hundred patients (100) presenting a complication after BPH surgery were included in this study in a total of 312 open prostatectomies performed. The postoperative complication rate was 32%. Seventy percent of the patients had at least one complication. Grade I and Grade II complications according to the modified Clavien's classification system were the most represented (87%). Two patients (2) died in the immediate postoperative period (Grade V). The presence of urethral catheter before surgery was identified as a risk factor for complication. A statistically significant difference was found in the group ICC ˃ 2 (Charlson Index of Comorbidity) for age parameter in the occurrence of complication. Conclusions: Open prostatectomy is associated with high morbidity in subjects with urinary catheters prior to surgery. Grade I and Grade II according to the modified Clavien's classification system were the most reported.
