Aims:
To characterize the prevalence and impact of nocturnal enuresis and overactive bladder (OAB) symptomatology in the adult sickle-cell disease (SCD) population.
Methods:
We performed a single-center, cross-sectional study of adult SCD patients from October 2012 to February 2014, using the validated Pfizer OAB short form questionnaire and brief voiding history surveys. Patient responses and scores were compared to that of controls having normal or sickle cell trait hemoglobin genotypes.
Results:
A group of 239 SCD patients (116 males, 123 females) were compared with 104 normal and 57 sickle cell trait patients. Seven of 239 (2.9%) SCD patients compared to none of the 161 patients without SCD (P = 0.04) reported current nocturnal enuresis. The median age of nocturnal enuresis cessation was higher in SCD patients (12.0, IQR 9.0-15.0 years) compared to that of both normal (7.5, IQR 6.0-9.8 years) and sickle cell trait (7.5, IQR 6.0-8.8 years) groups (P < 0.0001). Ninety-three of 239 (38.9%) SCD patients compared to 17 of 104 (16.3%) normal and 11 of 57 (19.3%) sickle cell trait had scores indicating OAB symptomatology (P < 0.0001). Patients with SCD had higher OAB symptom severity and lower health-related quality of life (HRQL) scores compared to the normal and sickle cell trait groups (P < 0.0001 and P < 0.0001, respectively).
Conclusions:
We demonstrate an elevated rate of nocturnal enuresis and OAB symptoms in the adult SCD population. An OAB phenotype may be an under-recognized complication of SCD irrespective of age. Neurourol. Urodynam. 35:642-646, 2016. © 2015 Wiley Periodicals, Inc.

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...

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...
01:26The 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...
