Objective : To evaluate the results of oncological and functional outcomes of laparoscopic radical prostatectomy (LRP)
during the first five years experience in Siriraj hospital.
Materials and Method: Between September 2004 and September 2009, the functional and oncological outcomes of
559 patients that underwent LRP were retrospectively evaluated.
Results : The distribution of pathological T stage was T2 (52.1%), T3 (39.9%), and T4 (2.9%). Lymph node metastasis (N1)
were found in 19 patients (3.4%). The positive margin rates in pT2a-b, pT2c, pT3a, pT3b and pT4 were 13.2%, 34.7%,
65.9%, 72.7% and 76.9%, respectively. The 3-year biological progression free survival (bPFS) rate for all patients was
87.2%. Three-year bPFS rates in pT2a-b, pT2c, pT3a, pT3b and pT4 were 96.3%, 93%, 75%, 55.6% and 62.5% respectively.
The continent rate at 12 months was 84% and potency rate at 12 months in group that received bilateral nerve sparing was
29.1%.
Conclusion : The oncological and functional results of our first LRPs in Thai men are acceptable and compared well with the
early experience of previous studies. However, longer follow up is needed for further evaluation.
