patients undergone RARP and PLND for not-metastatic patients undergone RARP and PLND for not-metastatic

Inclusion criteria

Patients were excluded from the study in case of postopera_x005ftive astomotic leakage.

Exclusion criteria

All procedures were performed by a single equip composed by experienced (>250 RARP) robotic surgeons. All patients had a standard six-port transperitoneal RARP as previously extensively reported in literature [6]. PLND was performed according to the preoperative 2012 Briganti nomogram. We performed extended PLND including the nodes overlying the common and the exterl iliac artery and vein, those within the obturator fossa located cranially and caudally to the obturator nerve, and the nodes medial and lateral to the interl iliac artery. According to the sur_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x005f_x0002_geon’s preferences, lymphatic vessels were sealed using three different techniques: extensive use of clipping for both large and small vessels, clips only on main vessels or vessels cauterization with the bipolar instrument. The peritoneum was not closed in any case after PLND. Abdomil draige was placed according to the surgeon’s choice and, if present, removed when the amount of lymph drained for a day (mL/24 h) was <50 mL. Postoperative ultrasound (US) examitions or CT scans were performed only in case of lymphocele suspicious, based on patient’s symptoms, or whether the draige supplied more than 400 ml for three consecutive days.

Keypoint

The increase of BMI was a significant predictor of symptomatic lymphocele development in pCa patients submitted to RARP and PLND.
