Functional Changes of Urogenital System After Holmium Laser Prostatectomy

Study Overview
=================
Brief Summary
-----------------
Holmium laser prostatectomy will enhance voiding function. Holmium laser prostatectomy will enhance sleep quality. Holmium laser prostatectomy will enhance renal function. Holmium laser prostatectomy will enhance erectile function. Holmium laser prostatectomy will enhance the health-related quality of life.

Detailed Description
-----------------
Check urodynamic parameters for voiding function evaluation Check low urinary tract symptoms (IPSS: international prostate symptom score) for voiding function evaluation Check Pittsburgh Sleep Quality Index for sleep quality evaluation Check estimated glomerular filtration rate and urine protein/creatinine ratio for renal function evaluation Check International Index of Erectile Function score (IIEF-5) for erectile function evaluation Check nocturnal penile tumescence parameters for erectile function evaluation Check 36-Item Short- Form Health Survey (SF-36) for evaluation of the health-related quality of life.
