RESUMO
PURPOSE: We attempted to evaluate the perioperative complications of holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia by using the modified Clavien classification system (MCCS). MATERIALS AND METHODS: Targeting 402 patients who underwent HoLEP for benign prostatic hyperplasia performed by a single surgeon between July 2008 and January 2011, we investigated complications that occurred during and within 1 month after surgery and classified them into grade I to grade V on the basis of the MCCS. If two or more complications occurred in one patient, each complication was graded and counted. RESULTS: The mean age, prostate volume, operation time, hospital stay, and average follow-up period of 402 patients who underwent HoLEP were 68.8 years (range, 52-84 years), 53.2 g (range, 23-228 g), 58.2 minutes (range, 20-230 minutes), 4.5 days (range, 2-7 days), and 9 months (range, 4-27 months), respectively; 78 complications occurred in 71 of the patients (morbidity rate, 17.6%). In MCCS grade I, complications occurred in 54 cases (69.2%); in grade II, complications occurred in 19 cases (24.3%); in grade III, complications occurred in 4 cases (5.1%); and in grade IV, 1 patient required intensive care unit care because of cerebral infarction (1.2%). There were no grade V complications. CONCLUSIONS: The HoLEP-based MCCS complications classification was performed very quickly. However, MCCS, when compared with other measures of endoscopic prostate surgery experiences, including HoLEP, exposed the lack of accuracy in low grade classification and the inability to include late complications.
RESUMO
PURPOSE: We developed an inverse technique for tissue morcellation by modifying the conventional upward technique and then examined its safety and efficiency. MATERIALS AND METHODS: From July 2008 to December 2010, a total of 389 consecutive patients treated with holmium laser enucleation of the prostate (HoLEP) were enrolled in this study. For tissue morcellation, we used an upward technique for an initial series of 84 patients and an inverse technique for a consecutive series of 305 patients. We compared efficiency and safety between the inverse technique and the upward technique. RESULTS: There were no significant differences in mean age or prostate volume between the two groups. The mean morcellation efficiency was higher in the inverse technique group. The incidence of severe bladder injury was significantly higher in the upward technique group. Regarding the site of bladder injury, 7 and 4 cases of bladder injury occurred in the bladder dome and posterior wall, respectively, in the upward technique group. In the inverse technique group, however, the site of bladder injury was limited to the trigone. We divided our clinical series of patients into the upward technique group and three inverse technique groups on the basis of the timing. The mean morcellation efficiency was significantly higher in all three inverse technique groups than in the upward technique group. However, there was no significant difference in mean morcellation efficiency between the three inverse technique groups. CONCLUSIONS: In conclusion, the inverse technique might be a more effective, safer, and more excellent method of morcellation than the conventional upward technique.
