Urodynamic Analysis of Taxi Drivers with Lower Urinary Tract Symptoms
Abstract
Purpose
Lower urinary tract symptoms (LUTS) in taxi drivers may be associated with many years of driving or bad voiding habits such as excessive inhibition of voiding and repetitive bladder over-distension. This condition may be treated under the false impression that the patient is suffering with benign prostatic hyperplasia or prostatitis. In this study, the urodynamic data of taxi drivers with LUTS were analyzed according to the storage and voiding symptom results.
Materials and Methods
45 patients who underwent urodynamic study were included in this study among all the taxi drivers who complained of LUTS and who were without benign prostatic hyperplasia, urethritis and a prostatitis history. All the patients took the International Prostate Symptom Score (IPSS) self-assessment test. We divided the patients into 2 groups according to the chief complaint of storage symptoms (group I, 21 cases) and voiding symptoms (group II, 24 cases). The age distribution, driving years and prostate size were similar between the 2 groups.
Results
The IPSS were 14.47±4.82 in group I and 13.91±3.49 in group II. Group II had larger maximal cystometric capacity than did group I (p<0.05). 4 cases of idiopathic detrusor overactivity (IDO) were observed in group I (p<0.05). Group II had a lower mean maximal flow rate than group I (p<0.05). The post-voiding residual urine volume and detrussor pressure at maximal flow were similar between the groups. There were 17 cases of pseudo-detrusor-sphicter dyssynergia observed in group II and 7 cases observed in group I (p<0.05). Detrusor underactivity (DU) was observed in 3 patients of group II.
Conclusions
There were abnormal findings such as IDO, bladder outlet obstruction (BOO) and DU on the urodynamic studies of the taxi drivers. IPSS is insufficient for the diagnosis of BOO and DU. Urodynamic study may be useful in establishing the correct diagnosis and treatment of taxi drivers.
