Effect of Detrusor Overactivity on Functional Outcomes After Holmium Laser Enucleation of the Prostate in Patients With Benign Prostatic Obstruction

초록

OBJECTIVE To investigate the effect of detrusor overactivity (DO) on functional outcomes after holmium laser enucleation of the prostate (HoLEP). MATERIALS AND METHODS One hundred ten men with benign prostatic obstruction were evaluated retrospectively. International Prostate Symptom Score, International Continence Society male questionnaire short form, 3-day voiding diary, and uroflowmetry with postvoid residual were evaluated preoperatively and at 3 and 6 months postoperatively. The patients underwent urodynamic study preoperatively and were divided into the DO group (58 of 110, 52.7%) and the non-DO group (52 of 100, 47.3%). RESULTS Patients in the DO group were older than those in the non-DO group (71.4 vs 66.4 years), although prostate volume and degree of obstruction were not significantly different between the 2 groups. All International Prostate Symptom Score and uroflowmetry parameters improved significantly at the 3- and 6-month follow-ups. Storage symptoms in both groups were comparable preoperatively (9.7 vs 8.6); these improved similarly in both groups during follow-up (5.0 vs 4.0, 6-month follow-up). The number of patients taking anticholinergics increased significantly after HoLEP, from a baseline of 17 patients to 49 patients at the 3-month follow-up and 39 at the 6-month follow-up. More patients in the DO group were taking anticholinergics at the end of the follow-up period (48.3% vs 21.2%). CONCLUSION Although the storage symptoms improved significantly in both groups, a significant number of patients with DO group took anticholinergics after HoLEP. We recommend that surgeons should counsel the possibility of taking anticholinergics in the early postoperative period to the patients with DO at baseline. (C) 2015 Elsevier Inc.
