The patients were dividedinto 3 groups according to size of prostate. A total of35 cases with prostate volume less than 30ml wererecorded as group 1, 27 cases with volume of 30 to50 ml were recorded as group 2, and 13 cases withvolume greater than 50ml were recorded as group3. Age, BMI, preoperative PSA, operation time,intraoperative bleeding volume, postoperative drainagevolume, indwelling time of catheter, indwelling time ofdrainage tube, total hospitalization time, pathologicalstage, surgical margin, urine control and biochemicalrecurrence were observed. Results: All operationswere performed under Da Vinci robot assistance, andno patient was transferred to open surgery. There wasno significant difference in age, preoperative PSA,BMI, operation time, intraoperative bleeding volume,postoperative drainage volume, indwelling time ofcatheter, total hospitalization time, pathological stage,rate of positive surgical margin and recovery of urinarycontinence between the groups. Indwelling time ofdrainage tube was longer in group with larger prostate,6.4 (±4.5) days in group 1, 6.3 (±2.9) days in group 2and 7.1 (±2.5) days in group 3. Gleason score was lowerin group with larger prostate, with statistical difference.Conclusion: Prostate volume had no significant effecton urinary control, rate of positive surgical margin andrecurrence after RARP. Gleason score of pathologicaltissue was lower and indwelling time of drainage tubewas longer in patients with larger prostate after RARP.Operation time and intraoperative bleeding volumeof large prostate patients underwent RARP need tobe further studied. RARP has certain advantages forpatients with large prostate.
