- Abstract
- OBJECTIVE To analyze the effect of Holmium laser enucleation of prostate (HoLEP) on overactive bladder (OAB) symptoms and urodynamic parameters in patients with benign prostatic hyperplasia. METHODS One hundred sixty-five patients were included in this prospective study. They complained of lower urinary tract symptoms suggestive of benign prostatic hyperplasia and underwent HoLEP by a surgeon from January 2010 to March 2012. We analyzed the results of International Prostate Symptom Score, overactive bladder questionnaire, frequency-volume chart, and urodynamic studies (UDS) before and after the surgery. Follow-up examinations were repeated 3 and 6 months postoperatively, and a UDS was performed at 6 months after the surgery. RESULTS The mean age was 68.4 (range, 52-91) years, the preoperative prostate volume measured by transrectal ultrasound was 71.1 (range, 22-202) mL, and the serum PSA level was 4.4 (range, 0.5-21.7) ng/mL. Postoperatively, patients showed significant improvement in the International Prostate Symptom Score (total score from 20.7 to 5.5, P < .001), overactive bladder questionnaire score (severity score from 24.8 to 12.5, P < .001), and frequency-volume chart parameters (daytime frequency, nocturia, and maximal capacity, respectively) (P < .001). The peak flow rate (P < .001), postvoid residual urine volume (P < .001), maximal cystometric capacity (P < .002), and bladder outlet obstruction index (P < .001) have improved significantly. The number of patients who showed involuntary detrusor contraction in UDS decreased significantly from 45.5% to 36.4% (P < .001). However, bladder compliance did not improve. CONCLUSION OAB symptoms and urodynamic parameters were improved significantly after HoLEP surgery in short-term follow-up. (C) 2014 Elsevier Inc.
