Outcome of Open Transvesical Prostatectomy for Benign Prostatic Hyperplasia: A Five-Year Descriptive Study at State Specialist Hospital, Osogbo, Nigeria

Background: Open transvesical prostatectomy remains a widely performed surgical treatment for benign prostatic hyperplasia in resource-limited settings. However, comprehensive long-term outcome data from Nigerian tertiary centers are unavailable. Objective: To evaluate the clinical/surgical outcomes and complications following open prostatectomy over a five-year period at State Specialist Hospital, Osogbo. Methods: A descriptive retrospective study was conducted reviewing all patients who underwent open transvesical prostatectomy between January 1, 2020, and December 31, 2024 at State Specialist Hospital, Osogbo. Data collected included patient demographics, clinical presentation, preoperative parameters, intraoperative findings, postoperative complications, duration of hospital stay, and follow-up outcomes. Data were analyzed using descriptive statistics. Results: During the study period, 192 patients underwent open transvesical prostatectomy of which sufficient preoperative and postoperative data were available for only 186 patients, and this was the final number of patients included in the analysis. The modal age was 70+ years (65.1% of the study population). The modal prostate volume was greater than 80 cm³. Preoperative complications were encountered in 29.6% of patient population, while postoperative complications were observed in 30.6% of patients. The modal hospital stay was 7-11 days. Conclusion: Open transvesical prostatectomy demonstrated favorable outcomes with moderate complication rates at our center. The findings highlight poor clinical documentation and follow up practice, missing pre-operative PSA data, prolonged catheter dependence pre-surgery and provide valuable baseline data for improving surgical practice in similar resource-limited settings.
