Abstract:
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.

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Ureters
The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...
Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
