Comparison of robot assistant radical prostatectomy by transperitoneal versus extraperitoneal approach / 中华泌尿外科杂志

ABSTRACT

Objective To compare the safety and oncological results of robot-assisted laparoscopic radical prostatectomy performed between transperitoneal and extraperitoneal approach.Methods 79 patients underwent transperitoneal robot-assisted laparoscopic radical prostatectomy (Tp-RLRP).The other 86 consecutive patients went through extraperitoneal robot-assisted laparoscopic radical prostatectomy (Ep-RLRP).Results All procedures were performed successfully without conversion.Total procedure time for Ep-RLRP was shorter than it for Tp-RLRP[(218.1 ± 54.4) min vs.(180.2 ± 47.1) min,P ＜ 0.001].Docking time for Ep-RLRP was longer than Tp-RLRP [(21.5 ± 7.1) min vs.(19.5 ± 5.7) min,P ＜ 0.001] Blood lost of Tp-RLRP was lesser than Ep-RLRP[(122.4 ± 71.0) ml vs.(140.4 ± 90.7) ml,P ＜ 0.05].There were no significant differences between two groups in terms of bowel function recovery,drainage tube reserve,foley catheter duration,etc.There were 19 patients (24.1％)and 4 patients (4.7％)were suffered lymph leakage in two groups separately,P ＜ 0.001.One delayed vesiclurethra hemorrhagic patient and one mesenteric torsion patient were happened in Tp-RLRP group.There were no significant differences between two groups in terms of surgical margin,biochemical recurrence and urine continence.Conclusion Compared to Tp-RLRP,Ep-RLRP can provide similar short-term oncological control,recovery of postoperative urine continence,shorter operation time and lower complication rates.
