A Comparative Study between Cystoscopy and Cystography in Detecting Bladder Diverticulae in Patients with Benign Prostatic Hyperplasia

Abstract

Background: Bladder diverticulae are mucosal outpunching and majority are acquired and secondary to either benign prostatic hypertrophy or the upper motor type of neurogenic bladder. Aim & Objectives: This study was undertaken to increase knowledge and understanding the presumed role of Benign Prostatic Hyperplasia (BPH) in the development of bladder diverticulae and to compare cystoscopy and cystography in detecting bladder diverticulae. Material and Methods: During a one year period, 74 patients with BPH, who were admitted in the hospital for surgery, were examined by cystoscopy and cystography to detect bladder diverticulae. Results: In this study, prevalence of bladder diverticulae was found to be 61%. There was a slight increase of bladder diverticulae with increasing age. We could not find any statistical difference between cystoscopy and cystography in detecting bladder diverticulae 2 (c =1.86, p value=.60, NS, p<0.05).Malignancy within diverticulae seen in 6.8% of cases. Conclusion: This study shows that the prevalence of bladder diverticulae is considerably high. Considering this high prevalence and potential complications, we suggest cystoscopy for the early diagnosis and possible treatment of bladder diverticulae in older patients with lower urinary tract symptoms
