RESUMEN
A multicenter study of the patients in whom the Urolume has been implanted has been among the actions undertaken by the Italian Club of Minimally Invasive Urology (UMICLUB). For each patient, a computer information format has been prepared containing evaluation data related to the preoperative period, the endoscopic procedure, and follow-up. The collected data were computerized through unifunctional and multifunctional analysis. Of the 82 patients recruited, 76 were followed for a period ranging from 1 to 40 months. Urinoflow results dramatically improved after implantation of the endoprosthesis: peak flow rates increased by 310%, while mean flow rates increased by 294%. Incontinence and dribbling were found in 4% and 20% of the patients, respectively, and were independent of the distance between the external sphincter and the Urolume prosthesis and of the stent number and length. The cross-data elaboration seems to indicate a statistically significant relation between urethral preparation before Urolume implantation and stricture recurrence, with recurrence being more frequent after dilation. Significant correlations have not been noticed between stenosis etiology, urinary infection, type of anesthesia, and recurrence; between the type of anesthesia, stent length, and duration of hospitalization; or between stent number and position and pain. The impact of the Urolume prosthesis on sexual activity was marginal by all three measures considered (pain during erection, coitus, and ejaculation).
