[Analysis of the absorcion's factors of irrigating fluid during transurethral resection of the prostate].

OBJECTIVES In this study it was our intention to evaluate the relation between the reabsorption of irrigating fluid and three variables: time of the intervention, volume of solution of glicina employee and weight of the fragments, during the RTU of prostate fulfilled to low hydraulic pressure. MATERIAL AND METHOD We study 74 patients that RTU of prostate was performed with suprapúbica derivation with Amplatz's pod 30 ch. The ethanol was monitored in expired air every 15 minutes during the intervention. Likewise we annotated the time of the intervention, the volume of glicina used and the weight of the fragments extracted. Statistically Anova's text was in use for comparison of averages. RESULTS 13,6% of the patients absorbed irrigating fluid in some quantity. The range of absorption belongs to 100 cc until 2.000 cc. We did not find a statistically significant difference in the averages of time of resection, volume of glicina and weight of the fragments between the group of patients that had absortion of irrigating fluid and they that didn't had. CONCLUSIONS Our data show that the operative time, the volume of irrigating fluid and the weight of the resected fragments do not influence the reabsorption of liquid of irrigation when a RTU is realized to low hydraulic pressure.
