Introduction: This study aims to assess the contributing factors of immediate post-operative emptying failure after transurethral benign prostatic hyperplasia (BPH) surgery
Methods: We retrospectively reviewed 631 patents data, who underwent BPH surgery from January 2008 to November 2015. Need to catheterization due to voiding difficulty within 24 hours after BPH surgery defined as immediate post-operative emptying failure. Multivariable analysis was performed to assessing contributing factors of immediate post-operative emptying failure. We also reviewed spontaneous voiding recovery after emptying failure.
Results: Average age was 69.2±7.7year, PSA level was 9.8±34.2ng/ml, and prostate volume was 58.8±36.1cc. Pre-operative AUR was a presence in 147 patients (24.3%), and 44 patients (7%) experienced recurrent event. Among the variables previous AUR history (OR 2.99; 95% confidence intervals (CIs) 1.41-6.33; p-value < 0.01) and acontractile detrusor activity (OR 9.60; 95% CIs 2.72-33.86; p-value < 0.01) were associated with immediate post-operative emptying failure after BPH operation. All the patient with emptying failure recovered voiding function with average 6.83±7.03 days, except one loss of follow up patient. There were no statistic differences in days need to recovery between with and without previous AUR history (8.19 ± 8.64 days vs. 4.89 ± 3.00 days, p-value = 0.10)
Conclusions: Although previous AUR history and decreased detrusor contractility are risk factor of immediate post-operative emptying failure, we could not avoid BPH surgery because almost 100% of patient recovered voiding function within several weeks. However, we should more carefully counselling before the surgery in these patients for the risk of immediate emptying failure. Source of
