Abstract
Purpose: We investigated the etiologies of lower urinary tract symptoms (LUTS) and compared urodynamic characteristics between different diagnostic groups in young men with chronic LUTS.
Materials and Methods: We reviewed the medical records of 308 men aged 18 to 50 years who had undergone a urodynamic study for chronic LUTS (≥6 months) without symptoms suggestive of chronic prostatitis.
Results: The men’s mean age was 40.4 (±10.1) years and their mean duration of symptoms was 38.8 (±49.2) months. Urodynamic evaluation demonstrated voiding phase dysfunction in 62.1% of cases (primary bladder neck dysfunction [PBND] in 26.0%, dysfunctional voiding [DV] in 23.4%, and detrusor underactivity [DU]/acontractile detrusor [AD] in 12.7%) and a single storage phase dysfunction in 36.4% of cases (detrusor overactivity [DO] in 13.3%, small cystometric capacity in 17.9%, and reduced bladder sensation in 5.2%). Most of the demographic characteristics and clinical symptoms did not differ between these diagnostic groups. Whereas 53.9% of patients with voiding dysfunction had concomitant storage dysfunction, 69.6% of those with storage dysfunction had concomitant voiding dysfunction. Men with DV or DU/AD exhibited lower maximum cystometric capacity than did those with normal urodynamics. Low bladder compliance was most frequent among patients with PBND (10.0%, p=0.025). In storage dysfunctions, men with DO exhibited higher detrusor pressure during voiding than did those with other storage dysfunctions (p<0.01).
Conclusions: Because clinical symptoms are not useful for predicting the specific urodynamic etiology of LUTS in this population, urodynamic investigation can help to make an accurate diagnosis and, potentially, to guide appropriate treatment.
