PURPOSE
Conventional urodynamics (CU) may fail in reproducing lower urinary tract dysfunction (LUTD).
CU is often unsuitable in pediatric population. Different factors may interrupt investigation or cause
misinterpretation of the results. In those cases ambulatory urodynamics (AU) can help to diagnose
LUTD such as overactive bladder (OAB). Furthermore, a normal CU in child with persisting com-
plaints doesn’t rule out OAB and AU may be useful in detection of underlying pathology. The aim of
our study was to evaluate the added value of AU in children.
MATERIAL AND METHODS
From 1/01/2014 through 30/09/2016, 16 patients (6 boys, 10 girls, median age 10.5 years) with
LUTD underwent AU. All patients were treated based on previous CU results. Main inclusion crit-
erium was inadequate result of therapy with persisting LUTD. AU was performed several weeks/
months after CU to reassess bladder function. Age was not an exclusion criterium. Vesical and
abdominal pressure was recorded outside hospital during an average of four hours using Bluetooth
technology. Patients were asked to void or to catheterize and to fill in micturition and activity diaries
in order to analyze events which provoke urine leakage.
RESULTS
The data of AU were compared with the CU. All of the results (100%) were evaluable and technically
feasible for diagnosis. In thirteen out of 16 patients (81.3%) AU showed detrusor overactivity (DOA)
which wasn’t documented previously on CU. Treatment was modified in fifteen out 16 patients
(93.8%) based on AU data, leading to satisfactory results in most of the patients.
CONCLUSIONS
Ambulatory urodynamics is a good tool for detection of DOA in children where previous conventional
urodynamics have failed to detect LUTD. When used correctly, it may give valuable information, on
which further treatment may safely be modified.
