Preoperative and postoperative patient evaluation
In these patients, validated
Korean version of International Prostate Symptom Score (I-PSS)
questionnaires were acquired preoperatively16. Prostate volume
measurement using trans-rectal ultrasonography, serum prostate specific
antigen (PSA) level examination, and uroflowmetry with post-voided
residual urine were also performed prior to surgery. In addition, UDS
was routinely performed before the surgery. At postoperative 1, 6, 12,
24, 36, 48, and 60 months, I-PSS questionnaires and uroflowmetry with
post-void residual urine were evaluated. Serum PSA level and prostate
volume were measured at postoperative 6 months.
