mean prostate volume (p[0.40), estimated blood loss (p[0.32), robotic console time (p[0.86) or major 30-day postoperative (Clavien>2) complications (p[0.80) between both groups. With regards to urinary function, the mean improvement in preoperative and postoperative AUASS (p[0.31) and QOL scores (p[0.11) were similar between both groups.CONCLUSIONS: For management of patients with enlarged prostates and LUTS, RASP is associated with an improvement in urinary function outcomes and a low risk of postoperative complications. Perioperative outcomes of RASP are similar in patients who underwent prior prostate surgery versus those that did not undergo prior prostate surgery.

Lymphoceles (LC) occur in up to 60% after robot-assisted radical prostatectomy (RARP) and pelvic lymphadenectomy (PLND). In 2–10%, they are symptomatic and may cause complications and require treatment. Data on risk factors for the formation of lymphoceles after RARP and PNLD remain sparse in the urologic literature and are inconclusive to date. The underlying data of this secondary analysis were obtained from the prospective multi-center RCT ProLy. We performed a multivariate analysis to focus on the potential risk factors that may influence lymphocele formation. Patients with LC had a statistically significant higher BMI (27.8 vs. 26.3 kg/m2, p < 0.001; BMI ≥ 30 kg/m2: 31 vs. 17%, p = 0.002) and their surgical time was longer (180 vs. 160 min, p = 0.001) In multivariate analysis, the study group (control vs. peritoneal flap, p = 0.003), BMI (metric, p = 0.028), and surgical time (continuous, p = 0.007) were independent predictors. Patients with symptomatic lymphocele presented with higher BMI (29 vs. 26.6 kg/m2, p = 0.007; BMI ≥ 30 kg/m2: 39 vs. 20%, p = 0.023) and experienced higher intraoperative blood loss (200 vs. 150 mL, p = 0.032). In multivariate analysis, BMI ≥ 30 kg/m2 vs. < 30 kg/m2 was an independent predictor for the formation of a symptomatic lymphocele (p = 0.02). High BMI and prolonged surgical time are general risk factors for the development of LC. Patients with a BMI ≥ 30 kg/m2 had a higher risk for symptomatic lymphoceles.
