Introduction:
Cloacal exstrophy (CE) is a severe midline congenital abnormality that requires numerous surgical corrections to achieve an acceptable quality of life. Candidates for urinary continence undergo multiple procedures, most often continent bladder diversions, to become socially dry. Here, the authors investigate the number of genitourinary interventions that patients with CE undergo to attain urinary continence.
Materials And Methods:
A retrospective review of a prospectively maintained database of 1311 exstrophy epispadias complex patients was performed. Patients with CE who have had at least one continence procedure were included. A continence procedure was defined as bladder neck reconstruction with or without augmentation, bladder neck transection with continent urinary diversion, augmentation cystoplasty, or use of injectable bulking agents. Continence was defined as a dry interval greater than 3 hours without leakage at night.
Results:
In total, 140 CE and CE variant patients have been managed at the authors' institution. Of the 116 CE patients, 59 received at least one continence procedure, 14 were excluded for incontinent diversion or cystectomy, and the remaining 43 patients are awaiting a continence procedure. At the time of analysis, 42 (71%) patients who underwent a continence procedure were dry. The median number of total urologic procedures to reach urinary continence was 4 (range 2-10). This included 1 bladder closure (range 1-3), 2 urinary continence procedures (range 1-4), and 1 (range 0-4) "other" genitourinary procedures. The median time to urinary continence was 11.0 years (95% CI [9.2-14.2]).
Conclusions:
A majority of CE patients who undergo a diversion procedure can achieve urinary continence. However multiple continence procedures are likely necessary. Of patients who are candidates for a continence procedure, half will be continent by the age of 11.
Level Of Evidence:
Level IV, Case series with no comparison group.

Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
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...
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...
