Incidencia y factores asociados al uso de medicamentos y retratamiento quirúrgico posterior a resección transuretral de próstata

Abstract

IntroductionTransurethral resection of the prostate (TURP) is a standard procedure for obstructive prostatic growth. Medical retreatment with anticholinergics, alpha-blockers, and 5 alpha reductase inhibitors is from 16 to 50%. A second surgical retreatment is associated with internal urethrotomy, cervicotomy, and re-TURP between 5 and 13% at 5 years. Re-TURP is associated with residual tissue. AimTo determine the incidence of and factors associated with the use of medications and surgical retreatment after TURP. Material and methodsA retrospective study was conducted on patients that underwent TURP within the time frame of January 2010 and December 2011 with follow-up to the present. Preoperative, intraoperative, and postoperative variables were analyzed and the chi-square test was used for the statistical analysis. ResultsFollow-up was carried out on 158 patients that underwent TURP. The overall accumulated incidence of retreatment was 43%, surgical retreatment was 17.7%, and medical treatment was 30.4%. TURP retreatment was 7.6% and transvesical prostatectomy was 1.3%. The mean time until prostate surgery retreatment was 30.5 months. Postoperative medical treatment was: anticholinergics 17.1%, alpha-blockers 15.2%, 5 alpha reductase inhibitors 6.3%, and combination 8.2%. During follow-up, 22.8% of the patients had residual tissue, which was the main cause of retreatment. Preoperative prostatic volume>80g was associated with residual tissue (p=0.024). ConclusionsIn our study, the incidence of surgical retreatment was higher than that reported in the literature, at 17.7% vs. 13%, respectively, and medical treatment was lower at 30.4% vs. 50%, respectively. Anticholinergics were the most utilized medications. Adequate patient selection will reduce complications and risk for retreatment.
