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

Introduction

Transurethral 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.

Aim

To determine the incidence of and factors associated with the use of medications and surgical retreatment after TURP.

Material and methods

A 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.

Results

Follow-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 > 80 g was associated with residual tissue (p = 0.024).

Conclusions

In 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.
