[Radical prostatectomy for localized prostate cancer]

We studied 81 patients who underwent radical prostatectomy for prostate cancer. Ten, 57 and 14 patients were clinically diagnosed with stage T1, T2 and T3, respectively. Pelvic lymph node dissection was performed prior to prostatectomy in all cases. The neurovascular bundle was preserved in 21 patients. Compared with pathological stage, the accuracy rate of clinical staging in T1, T2 and T3 was 40, 46 and 64% respectively. Approximately half of the patients clinically diagnosed with stage T2 were pT3. The positive rate of lymph node in pT2 and pT3 was 3.3 and 37% respectively, showing a marked difference between these two pathological stages. The 3-year non-recurrence rates were 89% in patients with pT2 and 79% in pT3. In the well differentiated carcinoma group, no patients had recurrence for up to 3 years. All of the patients with infiltration (INF) gamma showed recurrence within 3 years. Fifty-five patients had no problem on urination post-operatively, while the other 23 patients had a mild or moderate incontinence and the remaining 3 patients had a small urine stream. Regarding erectile potency, 4 out of 18 evaluable patients were potent.
