Bladder diverticulum caused by primary bladder neck obstruction. 

 -  2022 
<br/><br/> Here, we report a case of a patient in their mid 30s who presented with an elevated creatinine and was found to have a massive bladder diverticulum. The patient underwent a robotic-assisted diverticulectomy. They were later found to have a primary bladder neck obstruction on video urodynamics, and subsequently, underwent bladder neck incision, leading to significant improvement in urinary symptoms. Primary bladder neck obstruction is an overlooked cause of bladder diverticulum. While cystoscopy and cross-sectional imaging are frequently used in the initial evaluation of bladder diverticula, in the absence of an anatomic obstruction such as prostate enlargement, video urodynamics should be performed to assess for primary bladder neck obstruction.
