Cystitis Cystica Leading to Stricture of the Internal Urethral Orifice.

Cystitis cystica is a relatively common chronic reactive inflammatory disease caused by chronic irritation of the bladder mucosa. It is broadly considered one of the classifications of proliferative cystitis. The predilection site is the bladder trigone area, which may present with symptoms such as frequent urination, hematuria, and lower abdominal discomfort; however, it rarely causes bladder outlet obstruction. We present the case of a 59-year-old male patient suffering from incomplete urinary retention due to internal urethral orifice obstruction resulting from cystitis cystica. Following transurethral resection, the patient's dysuria rapidly improved, and the tumor did not recur.
