Abstract
Introduction Voiding dysfunction after a traumatic brain injury (TBI) occurs secondary to impaired
cognitive or behavioral functioning, brain damage, associated injury to the spinal
cord, and direct bladder trauma. In this study, the authors collected data on TBI
patients with neurogenic bladder dysfunctions to understand the spectrum of voiding
dysfunctions and to investigate the relationships of the severity of TBI with the
presentation of urinary tract dysfunctions.
Materials and Methods All consecutive patients with isolated TBI of Glasgow Coma Scale (GCS) (9–15) in
the postacute period and at 3 months were included in the study. In patients with
previous stroke or any other neurologic disorder or associated spine injury and with
urologic conditions such as benign prostatic hyperplasia (BPH), the urethral stricture
is excluded. After a successful voiding trial, uroflowmetry to see the flow pattern
and ultrasound of the abdomen and pelvis for post-void residual urine is done. A urodynamic
study is done in patients with poor urinary flow (< 15 mL/s), high post-void residual
urine (> 100 mL), and/or lower urinary tract symptoms.
Results During the study period, a total of 55 patients were enrolled in the study: 43 were
males and 12 were females. Out of 55 patients, 47 were treated conservatively and
8 were operated upon for TBI. Out of 55 patients, 26 had a poor stream on uroflowmetry
and 19 underwent urodynamic study either due to urinary symptoms or poor stream. Out
of the 19 patients, 9 had a urodynamic abnormality. Of the 19 patients who underwent
urodynamic study, there was no significant correlation (p = 0.23) between the TBI pathology and urodynamic abnormality. There was also no significant
correlation seen between site of lesion and urodynamic abnormality.
Conclusion The prevalence of urinary symptoms in mild and moderate TBIs is low (7.3); 47.7%
of patients had poor urinary flow. None of the patients had an abnormality in filling
phase. Nine patients had an abnormality in voiding phase and were treated with an
α-blocker.
Duration During 2012 to 2015.
