The incidence of diverticula of urinary bladder in patients with benign prostatic : hypertrophy and the comparison between cystoscopy and cystography in detecting bladder diverticula

Abstract EN

Abstract Background: The majorities of bladder diverticula are acquired and are secondary to either bladder outlet obstruction or the upper motor type of neurogenic bladder.

This study was undertaken to increase awareness and understanding the putative role of BPH (Benign Prostatic Hyperplasia) in the development of bladder diverticula and to compare cystoscopy and cystography in detecting bladder diverticula. Methods: During a 4-month period, 106 patients with BPH, who were admitted in the hospital for surgery, were examined by cystoscopy to detect bladder diverticula.

Thirty-one patients were selected randomly and underwent cystography. Results: In this study, the rate of bladder diverticula in patients with BPH was 27.4% by cystoscopy while by cystography, it was 48%.There was a slight increase of bladder diverticula with increasing age.

This research also depicted that the detection rate of diverticula cystography in of urinary bladder was much greater than that of cystoscopy. Conclusion: This study shows that the prevalence of bladder diverticula is considerably high.

The detection rate of cystography in diverticula of urinary bladder was much greater than that of cystoscopy.

Considering this high prevalence and potential complications, we suggest cystography for the early diagnosis and possible treatment of bladder diverticula in older patients with lower urinary tract symptoms.
