Insights
Enuresis and nocturia are common in children with sickle cell anemia (SCA). These conditions persist into adulthood and are not linked to increased pain or acute chest syndrome (ACS) episodes.
Area of Science:
- Pediatrics
- Hematology
- Urology
Background:
- Enuresis (bedwetting) and nocturia (frequent urination at night) are common in children.
- Sickle cell anemia (SCA) is a genetic blood disorder that can affect multiple organ systems.
- The prevalence and impact of enuresis and nocturia in individuals with SCA are not well-established.
Purpose of the Study:
- To determine the prevalence of enuresis and nocturia in children and young adults with SCA.
- To investigate the association between enuresis/nocturia and SCA-related morbidity, including pain and acute chest syndrome (ACS).
Main Methods:
- Analysis of a prospective infant cohort of African-American children with SCA.
- Inclusion of participants enrolled before 6 months of age with completed questionnaires on enuresis and nocturia.
- Data collection on enuresis and nocturia prevalence and correlation with SCA-related complications.
Main Results:
- Out of 213 participants, 33% experienced enuresis.
- Enuresis was most prevalent in children aged 6-8 years (42%) and persisted in young adults (9% aged 18-20).
- Nocturia was reported by 79% of participants. No association was found between enuresis/nocturia and increased pain or ACS episodes.
Conclusions:
- Enuresis and nocturia are highly prevalent in children and young adults with SCA.
- These urinary symptoms are more persistent in adults with SCA compared to the general population.
- Enuresis and nocturia in SCA patients are not associated with increased pain or ACS episodes.
Objectives:
Enuresis and nocturia are common among children with sickle cell anemia (SCA). The objectives of this study were to describe the prevalence of enuresis and nocturia among children and young adults with SCA and determine the relationship, if any, between these symptoms and SCA-related morbidity.
Methods:
A prospective infant cohort of African-American children with SCA was previously established from the Cooperative Study for Sickle Cell Disease. Included in this cohort were children with SCA enrolled before 6 months of age for whom questions about enuresis and nocturia had been completed.
Results:
A total of 213 participants were included in this analysis. Sixty-nine individuals (33%) experienced enuresis over the course of the study. No children under 6 years of age were asked about enuresis. Thereafter, enuresis was most prevalent between the ages of 6 and 8 years (42%) and continued to be common in young adults ages 18 to 20 years (9%). Seventy-nine percent of individuals reported a history of nocturia. There was no association between enuresis or nocturia and an increased rate of pain or acute chest syndrome (ACS) episodes.
Conclusions:
Enuresis and nocturia are common in children with SCA. Among adults with SCA, enuresis and nocturia are more persistent compared with adults in the general population. Enuresis and nocturia are not associated with an increased rate of pain or ACS.

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...

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 urine...
