CORRELATION OF TOOLS FOR OBJECTIVE EVALUATION OF INFRAVESICAL OBSTRUCTION OF MEN WITH LOWER URINARY TRACT SYMPTOMS

Resumo

PURPOSE: To identify how the most frequently used parameters in daily clinical practice diagnosing bladder outlet obstruction (BOO) due to benign prostate enlargement (BPE) correlate to each other.
METHODS: The study included 452 patients with lower urinary tract symptoms (LUTS) of the UNICAMP urology outpatient clinic of LUTS. Inclusion criteria: patients with BOO due to BPE who agreed to participate in the study. Exclusion criteria: patients with urinary tract infection, neurological diseases that compromised the lower urinary tract, prior prostatic surgery, radiotherapy or urethral stenosis. Patient assessment: history, international prostate symptoms score (IPSS), nocturnal quality of life score (NQoL) questionnaires, physical and digital rectal examination (DRE), PSA, transabdominal ultrasound with intravesical prostate protrusion (IPP), post-mictional residue and free uroflowmetry.
RESULTS: There was no strong Spearman correlation among the studied variables. The only moderate correlations occurred between IPSS and NQoL (p<.0001; c=.56) and between IPP and prostate volume (p<.0001; c=0.57). Weak correlations between IPP and post-mictional residue (p<.0001; c=.31) and free uroflowmetry (p<0001; c=-0.26); and between IPSS and free uroflowmetry (p<.0001, c=-.21).
CONCLUSION: In this study, we found moderate, weak, very weak and absent correlation between the various parameters used in the diagnosis and management of BOO due to BPE. As the value of these tools is variable, the creation of a logical and objective algorithm was not possible and the treatment is based on the interpretation of clinical symptoms.
