Holmium laser enucleation of prostate for patients in urinary retention.
OBJECTIVE
To evaluate holmium laser enucleation of the prostate in patients presenting in urinary retention secondary to benign prostatic hyperplasia.


METHODS
From May 2000 to May 2004, 169 patients, with a mean age of 74 years, who presented in urinary retention secondary to benign prostatic hyperplasia underwent holmium laser enucleation of the prostate. The mean urinary volume drained at catheterization was 670 mL (range 132 to 2000). All the patients were assessed preoperatively, 1, 3, 6, and 12 months postoperatively, and every year thereafter. All the patients were evaluated by physical examination, digital rectal examination, symptom evaluation using the International Prostate Symptom Score questionnaire, uroflowmetry (whenever possible), postvoid residual urine volume measurement, and prostate-specific antigen. The mean preoperative prostate volume estimated by transrectal ultrasonography was 101 cm3 (range 20 to 351).


RESULTS
The mean catheter time and hospital stay was 1.6 and 1.7 days, respectively. The peak urinary flow rate, postvoid residual urine volume, and International Prostate Symptom Score and quality-of-life score were significantly improved by 1 month after surgery and continued to improve during subsequent follow-up. Three patients (1.75%) were unable to void postoperatively; one required a suprapubic catheter and two used clean intermittent catheterization. Four patients (2.4%) were receiving anticoagulant therapy and required blood transfusion. Bladder neck contracture and urethral stricture developed in 1.7% and 1.2%, respectively.


CONCLUSIONS
Holmium laser enucleation of the prostate represents a safe and effective treatment for patients with benign prostatic hyperplasia presenting in urinary retention. It has low morbidity and provides immediate symptom and voiding improvement.
