| Sumario: | Introduction: Bladder Outlet Obstruction (BOO) due to prostaterelated diseases can lead to changes in bladder wall resulting
in detrusor wall thickening. These changes are time-dependent
and may reflect the severity of underlying BOO. Although
urodynamic tests are considered to be the gold standard for the
assessment of the severity of Lower Urinary Tract Symptoms
(LUTS), these are time-consuming, invasive and expensive. The
Detrusor Wall Thickness (DWT) measurement has emerged as
a cheap, non invasive and reproducible alternative means of
assessing the severity of LUTS in men with BOO.
Aim: To determine the correlation between the DWT and
International Prostate Symptom Score (IPSS) in men being
evaluated for prostate-related BOO/LUTS.
Materials and Methods: A cross-sectional hospital based study
was conducted over a period of 12 months (May 2014 to April
2015), at Urology Clinics of the Nnamdi Azikiwe University Teaching
Hospital (NAUTH), Nnewi. All 100 new consecutive male patients
aged ≥40 years with prostate-related LUTS and who can achieve
bladder volume of >250 mL were included in the study. The DWT
was measured at three different sites (anterior, lateral and dome) at
bladder volume >250 mL. Ethical approval was attained from the
institutional ethical review board. Severity of LUTS was assessed
using a validated IPSS questionnaire. Data was analysed using
SPSS version 20. Spearman’s correlation was used to assess the
correlation. The p-value <0.05 was considered significant.
Results: A total of 100 men with the mean age of 71.02±9.10
years were studied. The mean duration of symptoms was
30.63±26.60 months with the average IPSS being 20.94±6.13.
A total of 43 patients and 57 patients had moderate and severe
LUTS, respectively. None of the patients had mild LUTS. The mean
anterior, lateral, dome and average DWT measurements were
4.95±2.36 mm, 4.96±2.37 mm, 5.02±2.34 mm and 4.97±2.35 mm,
respectively. A total of 97 patients had DWT ≥2 mm. There was
a significant positive correlation between the DWT and IPSS
(r2
=0.635 and p<0.001).
Conclusion: The positive correlation between the DWT and
IPSS has demonstrated that the DWT measurement can be used
in assessing the severity of LUTS in men with prostate-related
diseases. |
