Abstract/OtherAbstract:
PURPOSE: To compare the safety and surgical outcomes in the patients with different prostate sizes undergoing diode laser enucleation of prostate. MATERIAL AND METHODS: From 2008 to 2012, consecutive patients with benign prostatic obstruction undergoing DiLEP at our institute were enrolled for analysis. A single surgeon did DiLEP with end-firing, continuous wave diode laser (980nm). Based on preoperative prostate volume determined with trans-rectal ultrasonography, patients were stratified into two groups: <60ml (Group 1, n=65) and ≥60ml (Group 2, n=55). The baseline and peri-operative characteristic, and postoperative surgical outcomes were compared between the two groups. RESULTS: Totally, 120 men aged 70.2±9.0 years were enrolled for analysis. Compared with the Group 1 patients, the Group 2 patients had larger total prostate volume (85.0±24.6 vs. 40.9±10.8 ml), longer operation time (117.7±48.2 vs. 60.7±25.0 minutes), higher retrieved weight of prostate (37.3±16.1 vs. 12.5±7.3 gm), and higher tissue retrieval ratio (74.4±22.2, vs. 58.8±23.2%, p<0.01). There was no significant difference in postoperative hemoglobin drop between the two groups (median 0.5 vs. 0.9 mg/dl, p=0.11). The rate of temporary postoperative urinary retention after removal of Foley catheter was significantly lower in the Group 2 patients (15.4% vs. 3.6%, p=0.04). Postoperative improvements in peak flow rate, post-void residual urine volume, and International Prostate Symptom Score were comparable between the two groups. CONCLUSIONS: Though the patients with larger prostates required significantly longer operation time and laser energy, the voiding function improvements and surgical complication rates in DiLEP were comparable between the patients with larger or smaller prostates.
