Clinical observation of holmium laser enucleation of the prostate in the treatment of benign prostatic hyperplasia and overactive bladder / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate clinical efficacy of holmium laser enucleation of the prostate in the treatment of benign prostatic hyperplasia (BPH) and overactive bladder (OAB).</p><p><b>METHODS</b>From May 2007 to May 2010, a total of 37 patients diagnosed BPH and OAB were treated by holmium laser enucleation of the prostate. After a mean follow-up of 4.9 months postoperatively, indices such as International Prostate Symptom Score (IPSS), quality of life (QOL) score, maximum flow rate (Qmax), residual urine volume and video urodynamics were monitored and statistically analyzed.</p><p><b>RESULTS</b>The mean preoperative IPSS and QOL score were 29.6 ± 5.2 and 4.3 ± 0.9, and decreased to 4.6 ± 1.2 and 1.2 ± 1.0 postoperative. The mean Qmax was (6 ± 3) ml/s preoperative and increased to (21 ± 5) ml/s postoperative. Preoperative average residual urine volume was (167 ± 11) ml, decreased to (41 ± 18) ml after operation. During follow-up, 86.5% patients' symptoms and quality of life improved continuously, however 13.5% patients existed residual postoperative OAB symptoms.</p><p><b>CONCLUSIONS</b>When BPH with OAB patients exist bladder outlet obstruction, bladder outlet obstruction should be relieved first then OAB symptoms can be relieved in majority of patients, but some patients have residual symptoms.</p>
