Abstract
Our study was conducted on 75 patients with lower urinary tract symptoms and aging more than 18 years old, admitted through the outpatient clinic of Urology in Ain Shams University Hospitals and Ahmed Maher Teaching Hospital through the period from 1/2020 to 10/2020.
It is well known that BOO is associated with morphologic changes in the prostate and urinary bladder, which together cause the symptom complex of BPH. These morphologic changes can be easily evaluated by pelvic USG. So bladder wall thickness can give us a better and easier option to diagnose BOO.
Free uroflowmetry, PVR urine volume are widely used noninvasive tests for the evaluation of patients with BPH and are useful for the diagnosis of voiding dysfunction. However, the results of these tests are insufficient to decide the optimal treatment option for an individual patient, as these tests are affected by various factors that may give misleading results. This, in turn, may limit their usefulness in determining the severity of BOO.
As a result, the presence of BOO should be investigated in patients with LUTS. It is obvious that urodynamic evaluation, which is the gold standard for BOO diagnosis, cannot be used on a daily basis for every patient. Even though the methods such as uroflowmetry, PVR evaluation, and prostate volume are frequently used for the determination of BOO, their diagnostic values are limited. Therefore, BWT measurement gains value as a method with high diagnostic value and easy applicability. The use of BWT measurement in clinical practice for the evaluation of BOO seems to be a simple method and augment the clinical diagnosis of obstruction and justify medical treatment.
In our study showed that USG measurements of BWT is useful in the diagnosis of symptomatic BOO. Moreover, the easy measurement of BWT, by suprapubic USG makes these parameters acceptable to both patients and physicians, and can be used for routine clinical evaluation of patients with symptomatic BOO. Further studies should be done to prove or deny the role of DWT measurement in patients with LUTS either because of obstruction, hypotonic bladder or other voiding dysfunction.
