OBJECTIVE: To evaluate surgical outcomes of patients who underwent complete or incomplete enucleation technique during a short-term postoperative period.
MATERIALS AND METHODS: Patients having intractable lower urinary tract symptoms/benign prostatic hyperplasia and prostates >30 g with obstructed pattern in the urodynamic examinations were included. They underwent transurethral resection of prostate (TUR-P), 120 W GreenLight laser high power system-photoselective vapoenucleation of prostate (HPS-PVEP), or holmium laser enucleation of prostate (HoLEP). Patients with the size of remnant prostates minus surgical defects <25 g were grouped into the completely enucleated group (group C), and others were grouped into the partially enucleated group (group P).
RESULTS: Mean prostate-specific antigen value was 3.5 ± 4.5 ng/mL, and mean prostate volume was 58.4 ± 31.0 mL. Complete enucleation rates in TUR-P, HPS-PVEP, and HoLEP groups were 39% (37 out of 95), 54.6% (83 out of 152), and 54.4% (31 out of 57), respectively. Complete enucleation rate of the TUR-P was significantly lower than those of the other 2 groups. Compared with group C, group P had lower maximal flow rate, higher bladder outlet obstruction index, and higher overactive bladder symptom scores. Multivariate logistic regression analyses showed that smaller prostate, presence of intravesical prostatic protrusion, HoLEP operation, and surgeons' experience were significant predictors for achieving complete enucleation of prostate. Voiding subscores of group C were significantly higher than those of group P at postoperative 12 months.
CONCLUSION: The performance of HoLEP was superior to other surgical techniques. However, HPS-PVEP with vapoenucleation showed the comparable enucleation rate with that of HoLEP. Complete enucleation was effective in maintaining outcomes of prostate resection, especially voiding subscores.
