Abstract
PURPOSE: We determine whether outcomes of holmium laser enucleation of the prostate are similar in patients with and those without preoperative urinary retention. MATERIALS AND METHODS: From May 2008 to July 2014, 231 patients underwent holmium laser prostate enucleation for symptomatic benign prostatic hyperplasia. Retrospective analysis was performed to evaluate for differences in postoperative outcomes for patients with and those without preoperative urinary retention. RESULTS: Overall 95 patients (41%) had urinary retention before holmium laser prostate enucleation while 136 (59%) did not. Mean followup for all patients was 15.3 months. Patients with retention tended to be older, have larger prostates, and have higher scores on the AUA SS and bother questionnaires (all p <0.05). Postoperatively there was no difference in rates of complications, including urinary retention. Both groups showed significant improvement in AUA SS and bother score after the procedure at all postoperative points. Median post-void residual was less than 60 ml and median maximum flow rate on uninstrumented uroflow was greater than 18 ml per second at all postoperative points for all patients regardless of preoperative retention status. No patients required long-term catheterization and rates of postoperative complications did not differ significantly during the followup period. CONCLUSIONS: This study represents the first direct comparison to our knowledge of holmium laser prostate enucleation outcomes in patients with or without urinary retention. There was no increased risk of postoperative urinary retention in patients with preoperative retention, and both groups demonstrated significant postoperative improvement in subjective and objective voiding measures.
