Differences in surgical and functional outcomes in benign prostate hyperplasia patients with only lower urinary tract symptoms versus those in retention: A systematic review and meta-analysis.

Preoperative UR patients undergoing surgery for BPH have higher risk of postoperative complications versus LUTS only group including the need for permanent catheterization. Both groups had similar long-term functional outcomes. We could infer that patients with UR on whom surgery is successful, with time may recover bladder function akin to patients with LUTS alone.
