Perioperative Parameters Operative Time

As shown in Table 1, the average operative time has declined substantially with increased experience.

The average operative time from Montsouris, the center with the largest reported experience of laparoscopic radical prostatectomy, declined from more than four hours for the first 100 cases to 2.9 hours for the last 350 cases (17). Similarly, Hoznek et al. (18) reported that the operative time averaged over eight hours for their first 20 cases and declined to four hours for the next 114 cases. Other reports worldwide describe similar declines in operating times after the initial experience. Pelvic lymphadenectomy, which at most centers is performed only in selected, high-risk patients, appears to add 30-60 minutes to the operative times in most series. In our contemporary series from Memorial Sloan-Kettering Cancer Center, the average operative time is 3.3 hours with bilateral pelvic lymph node dissection in performed in 45% of the patients.
