Objective: The aim of this study was to determine whether robot-assisted laparoscopic radical prostatectomy (RALP) performed within either 2 or 4weeks of prostate biopsy is associated with surgical difficulty or immediate postoperative outcome. Methods: Of the 121 patients that underwent RALP at our institution, 104 patients were prospectively included. Patients were sequentially divided into three groups: first patient in group A (interval from biopsy to RALP: 2weeks), second patient in group B (2-4weeks), third patient in group C (more than 4weeks), fourth patient in group A, and so on. The clinical, operative, pathological, and postoperative functional data were collected. Results: Group A consisted of 31 patients, group B of 33, and group C of 40 patients. Median patient age and median follow up were 61.1years and 14.1months, respectively. In group A, mean estimated blood loss was significantly higher than the other two groups, even though there was no significant difference in the mean console time. Postoperative complications did not make any difference among the groups. In the multivariable analysis, the interval from biopsy to surgery did not affect operative times or surgical margins, or the immediate postoperative outcomes (e.g. recovery of erectile function, continence, and biochemical recurrence). Conclusion: A short interval for less than two weeks between the prostate biopsy and the RALP seems to be feasible and safe. Further studies with larger samples are needed to corroborate these findings.
