Purpose: We reviewed our experience with a conservative medical program and
computer game assisted pelvic floor muscle retraining in patients with voi
ding dysfunction to substantiate our previous findings that demonstrated im
provement and/or cure in a majority of patients, and identify factors that
may be associated with unsuccessful treatment.
Materials and Methods: All patients presenting with symptoms of dysfunction
al voiding enrolled in our pelvic floor muscle retraining were examined. Ca
ses were subjectively evaluated for improvement of nocturnal enuresis, diur
nal enuresis, constipation, encopresis and incidence of break through urina
ry tract infection. Patients in whom our initial conservative approach that
included our biofeedback program failed were further treated with medicati
on, and outcomes were reviewed as well. Fisher's exact test was used for st
atistical analysis to identify factors that may predict failure with our pr
ogram.
Results: During the last 2 years 134 girls and 34 boys were enrolled in the
pelvic floor muscle retraining program. Of the patients 160 (95%) were com
pliant with the program. Mean patient age was 7.6 years (range 4 to 18). Th
e average number of hourly treatment sessions was 4.9 (range 2 to 13). Urof
lowmetry and electromyography demonstrated a flattened flow pattern with in
creased post-void residual volume in 32% of patients, flattened flow patter
n with normal post-void residual 47%, staccato flow pattern with increased
post-void residual 11% and staccato flow pattern with normal post-void resi
dual 10%. Subjective improvement was demonstrated in 87% (146) of patients,
while 13% (22) had no improvement. Statistically significant predictors of
failure included bladder capacity less than 60% of predicted volume (p <0.
03) and patient noncompliance (p <0.04). Twelve patients who had no improve
ment with biofeedback were treated with medication and 10 (83%) improved. M
ultichannel urodynamics or spinal magnetic resonance imaging (MRI) was obta
ined in only 7 (4%) of our patients with no neurological lesion identified
by spinal MRI.
Conclusions: A conservative program combined with computer game assisted pe
lvic floor muscle retraining improves symptoms in most patients with voidin
g dysfunction. A majority of patients can be treated without medication. Ho
wever, in a select population of patients with a small capacity bladder in
whom biofeedback fails, anticholinergic medication appears to alleviate sym
ptoms. In our experience almost all patients presenting with symptoms of vo
iding dysfunction can be treated without multichannel urodynamics, spinal M
RI or medication.
