ABSTRACT

The Unidad de Urodinamia y Disfunción Sexual del Hospital Español de México presents its experience with the noninvasive urodynamic uroflowmetry study and the quantification of post void residual urine for diagnosis of benign prostatic hyperplasia (BPH). It were analyzed 1,196 men, 440 were considered normal with ages between 40 and 93 years old with a median age of 61.8 years, on the uroflowmetry its Qmax were 22.5 mL/s. It were also clinically, evaluated 756 patients with ages between 40 and 99 years old with a median age 67.3. Its Qmax were 10.45 mL/s and it was undergone the diagnosis of obstructive lower urinary tract syndrome by BPH through uroflowmetry and post void residual urine. Our results confirm the maximum flow rate (Qmax) as the main measurement of the uroflowmetry. The post void residual urine quantification furnishes a good additional information when is related with Qmax and the flow pattern in urinary obstructive problems. It was also studied a randomized group of 84 patients with clinical manifestations of BPH in the last three years. They were evaluated with the IPSS (International Prostate Symptoms Score) in three groups. All of them had a very good correlation among the clinical manifestations (minor, moderate and severe). Qmax and post void residual urine. It was confirmed a statistical relations among the different types of obstructive flow patterns (from I to IV) and unobstructive flow pattern. Qmax is considered the most important value that established correlation with post void residual urine. The utility of pressure-flow study by voiding cystomanometry is discussed as a miniinvasive procedure.
