Positive urine culture under indwelling urethral catheterization is a risk factor for febrile complications after holmium laser enucleation of the prostate (HoLEP).

Abstract

To investigate the incidence of and risk factors for febrile complications (FCs) in patients undergoing holmium laser enucleation of the prostate (HoLEP). This retrospective study enrolled 847 consecutive patients who underwent HoLEP in our hospital from June 2006 to December 2018. FCs were defined as a body temperature ≥38.0°C within 30 days after surgery. The incidence of FCs was determined and possible risk factors assessed using multivariate logistic regression analysis. Overall, 87 (10.3%) patients presented with FCs, and 6 (0.7%) had urosepsis, with no fatal complications. Multivariate logistic regression analysis revealed that patients with preoperative positive urine culture and urethral catheterization had an increased risk of FCs compared with those with a negative culture who did not need catheterization (odds ratio [OR] 2.587, 95% confidence interval [CI] 1.307-5.121). A negative urine culture with catheterization and a positive culture without catheterization were not associated with the development of FCs (OR 0.320, 95% CI 0.040-2.553 and OR 1.370, 95% CI 0.662-2.365, respectively). Other significant risk factors included preoperative serum albumin levels (OR 0.382, 95% CI 0.173-0.846) and immediate postoperative body temperature (OR 2.559, 95% CI 1.549-4.230). FCs are relatively common among patients after HoLEP despite preoperative prophylactic antibiotic administration. Surgeons may need to consider performing screening of urine cultures prior to HoLEP, especially in patients with urethral catheterization, even if asymptomatic. If the culture is positive, prophylactic antibiotics should be tailored according to bacterial susceptibility.
