Insights
Infrequent Voider Syndrome, or Lazy Bladder Syndrome, involves large bladder capacity and residual urine in children. Early diagnosis through monitoring infrequent urination or large bladder capacity is crucial for effective treatment and preventing complications like vesico-ureteral reflux.
Area of Science:
- Pediatric Urology
- Functional Pediatric Urology
Background:
- Infrequent Voider Syndrome (IVS), also known as Lazy Bladder Syndrome, is characterized by a large bladder capacity and significant residual urine.
- Patients often present with recurrent urinary tract infections without upper urinary tract anomalies.
Observation:
- A case of a young girl with undiagnosed Lazy Bladder Syndrome and one-sided 20-degree vesico-ureteral reflux is presented.
- The patient had a history suggestive of IVS but lacked a prior diagnosis.
Findings:
- Prompt bladder training was initiated for the patient.
- After 9 months of follow-up, the patient achieved physiological micturition without evidence of vesico-ureteral reflux.
Implications:
- Highlights the importance of considering infrequent micturition or incidentally noted large bladder capacity in pediatric case histories.
- Emphasizes that early recognition of these signs can lead to timely diagnosis of Lazy Bladder Syndrome.
- Suggests bladder training as an effective intervention for IVS-related vesico-ureteral reflux.
Abstract:
The Infrequent Voider Syndrome or Lazy Bladder Syndrome in children is characterized by a large capacity bladder, frequently associated with a significant volume of residual urine. Usually these patients arrive at medical examination with a history of recurrent urinary infections but without anomalies in the upper urinary tract. We report about a young girl affected by one-sided 20 degree vesico-ureteral reflux due to Lazy Bladder Syndrome that had never been diagnosed before. This patient has been submitted to a prompt bladder training and seems presently to have at last gained a physiological micturition after 9 months of follow-up,without actual evidence of vesico-ureteral reflux. Therefore we must stress that it is prominently important considering every notice about infrequent micturition in a paediatric case history or a large capacity bladder, noticed by chance too. These reports may be fundamental for early diagnosis of Lazy Bladder Syndrome.

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 urine...
01:20Disorders 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...

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...
