Factors influencing the number of dialysis sessions associated with urological interventions

Abstract

ABSTRACT Introduction. The purpose of the study was to determine whether the following 4 factors: age, sex, type of intervention and type of dialysis (acute or chronic), have an influence on the number of dialysis sessions associated with urological interventions. Material and methods. The study included almost 3000 patients undergoing dialysis, during a 3 year period, in 3 university hospitals in Bucharest, Romania. In the end, after applying the inclusion and exclusion criteria, the study group consisted of 89 patients. The time frame in which the number of dialysis sessions was evaluated started from the moment the patients entered urological surveillance for undergoing a urological intervention until the patients where discharged. Results. Out of the 4 factors, the following statistically significant differences were encountered: the mean number of dialysis sessions was lower in patients under 50 years than in those older than 69 years (p<0,05, p=0,02) and the mean number of dialysis sessions was lower for chronic dialysis than for acute dialysis (p<0,05, p=0.038). Conclusions. While the number of elderly patients required more dialysis sessions than the younger patients in association with urological interventions, there were no significant differences regarding the sex of the patient. Although there were no significant differences regarding the type of urological interventions, the acute onset of the renal insufficiency associated with acute dialysis required a larger number of dialysis sessions than the patients already on chronic dialysis at the time of surgery.
