Pre-therapeutical assessment of lower urinary tract symptoms in adult men: Systematic review and clinical practice guidelines.

INTRODUCTION

The aim was to propose initial and pre-therapeutical assessment of lower urinary tract symptoms in adult men through a systematic review and clinical practice guidelines.

METHODS

These guidelines were based on a systematic review performed between January 2011 and November 2021 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. The protocol was registered in the International Prospective Register of Systematic Reviews database (CRD42022336418). The recommendations and the methodology of elaboration were prospectively validated by the French Health Authority (Haute Autorité de santé [HAS]).

RESULTS

In total, 1662 publications were screened for eligibility and 311 met the inclusion criteria, 167 studies were retained among them 17 guidelines from French, European or International institutions. Perform on initial evaluation: identification of cardiovascular risk factors, metabolic syndrome, current medication, urinary and sexual symptoms (by structured interview or validated self-questionnaires), physical examination (lumbar fossa, pelvis, prostate, genitalia), urinalysis (dipstick or microscopy), abdominal ultrasound of the urinary tract (kidneys, bladder, prostate), post-void residual urine measurement (by ultrasound or automated measurement; under physiological conditions). Micturition flowmetry is recommended (except for general practitioners). Update and complete initial assessment before medication, interventional or surgical treatment if too old or incomplete. Perform a preoperative assessment (bleeding risk, infectious risk, geriatric risk). Urodynamic assessment, endorectal ultrasound and cystoscopy should not be systematically performed (only if additional information is needed). Perform urodynamics and urethrocystoscopy in case of failed interventional or surgical treatment. Following the initial workup, it is recommended to refer the patient to a urologist in case of: macroscopic hematuria, recurrent urinary tract infection or persistent perineal and/or suprapubic pain, persistent microscopic hematuria or leukocyturia in absence of urinary tract infection, predominant storage-phase symptoms, abnormal examination of the genitals or suspected prostate cancer, urinary retention, urinary tract stones, ureterohydronephrosis or morphological abnormalities of the prostate or the urinary tract.

CONCLUSION

These guidelines aimed to define the recommended investigation for LUTS in adult men at diagnosis, before medical treatment and before surgical and interventional treatments, in order to better personalize management and avoid unnecessary and/or invasive examinations.
