Preoperative factors affecting TURP postoperative outcomes

Abstract

OBJECTIVES: To determine whether preoperative patient specific characteristics, presenting symptoms, renal status, medical treatment and patient comorbidities have an effect on TURP outcome by looking at postoperative variables such as trial without catheter (TWOC) success, long term catheter dependence, complication rate and follow-up duration.

METHODS: Data was collected retrospectively from patients >40 years who underwent TURP and were followed up postoperatively between January 2014 and March 2015 in Malta’s state hospital. Preoperative and postoperative variables were collected and compared using Fisher’s exact test, independent sample t-test and one-way ANOVA.

RESULTS: A total of 141 males were included, with 85 patients (60.3%) being catheter free with no or mild lower urinary tract symptoms reported in their last follow-up visit. Statistical significance was noted between indication of surgery and catheter dependence postop (LUTS vs AUR p=0.029; LUTS vs CUR p=0.003; LUTS vs any retention p=0.003). Poor preoperative renal status prior to surgery also increased the risk of remaining catheter dependent (p=0.008) and of having failed postoperative trial without catheter (p=0.004).

CONCLUSION: Patients undergoing a TURP locally had an overall successful outcome. Late presentation for TURP and a diminished renal function are associated with a poor postoperative outcome.
