Abstract

Herniation of bladder mucosa through the bladder wall muscle layer is known as bladder diverticulum. The incidence of bladder diverticulum is 1 to 7% of the urinary bladder. About 0.8 to 10% of the urinary bladder diverticula develop carcinoma. Transitional cell carcinoma is the most common one. Painless haematuria is the most common clinical presentation. Different imaging modalities along with cystoscopy are the key for accurate diagnosis and staging. High grade multifocal urothelial carcinoma in bladder diverticulum is better managed by radical cystectomy and standard pelvic lymph node dissection with ileal conduit. Here, we report a case of a 66-year-old man with high grade multifocal urothelial carcinoma in bladder diverticulum managed with radical cystectomy and standard pelvic lymph node dissection with ileal conduit. Urologists in Nepal deal with adequate number of urinary bladder cancers. Such cases have been addressed adequately in the literature, but we did not find any case report from Nepal.

Keywords: Bladder diverticulum, radical cystectomy, urothelial carcinoma
