Risk Factors for Surgical Site Infection (SSI) after Urological Surgery: Incisional and Deep-organ/space Experience at Anjo Hospital

Abstract

Objective: In urological operations, many endourological procedures and pre-existing urinary tract infections may cause surgical complications. It is essential to identify the risk factors for surgical site infections (SSI) and determine additional influences. Patients and Methods:In the present retrospective investigation, a total of 324 patients who underwent open urological surgery between January 2003 and December 2007 at Anjo-Kosei Hospital were assessed for SSI along with possible associated factors. Results: Forty-four cases (13.6%) proved positive for SSIs during the surveillance period. Among these, 31 demonstrated incisional SSI and 13 demonstrated deep/organ space SSI. Greater age and body mass index, low preoperative haemoglobin levels, long preoperative hospital stay, prolonged operation time and increased blood loss during surgery were all positively associated with SSI in general. For the deep/organ space SSI cases, advanced age, low preoperative haemoglobin levels, long preoperative hospital stay and prolonged operation time were significant factors. Conclusion: This study identified several independent predictors of SSI in general, as well as deep/organ space infection, for urological open surgery at our hospital. The results provided a basis for urologists to decrease the incidence of urological SSI.

Surgical site infections and other healthcare related infections in cohort of urological patients, 2010-2013

“…Stope incidencije IOM i BI u pacijenat nakon uroloških operacija variraju u zavisnosti od vrste operativnih procedura, ali i od zemlje u kojoj su radjena istraživanja. U retrospektivnoj studiji Sawaia i saradnika u kojoj je nadzorom obuhvaaeeno 324 pacijenata podvrgnutih otvorenim urološkim operativnim procedurama izmerena stopa incidencije IOM je 13.6% 17 . U populaciji pacijenata obuhvaaeenih našom studijom najniža stopa incidencija IOM je uoèena kod operacija na bubregu tipa totalnih nefrektomija (2.4%) i parcijalnih nefrektomija (3.6%), a najviša kod operacija na mokraaenoj bešici tipa totalnih cistektomija (21.6%) i parcijalnih cistektomija (23.5%).…”

“…U studiji prevalencije BI mokraaenog sistema sprovedenoj u 194 urološka odeljenja u Aziji i Evropi, u koju je ukljuèeno 6033 pacijenta, utvrdjeno je da su nezavisni faktori rizika za njihov nastanak pored plasiranog UK i postojanja prethodne infekcije mokraaenog sistema, i dužina preoperativne hospitalizacije 22 . Dužina preoperativne hospitalizacije uoèena je kao nezavisan faktor za nastanak IOM u seriji operisanih uroloških pacijenata u Japanu 17 . U našoj studiji dužina preoperativne hospitalizacije u multivarijantnoj analizi se pokazala kao nezavisan prediktor za nastank IOM u operisanih pacijenata (RR:0.909; 95%CI: 0.880 -0.939; SE: 0.017; p: 0.000).…”
