All patients died in our follow-up, with an average overall survival (OS) of 12.09 months (1.90-26.77 months). As a rare renal tumor, renal PNET has a propensity to occur in young males. Most patients have distant metastasis when they are diagnosed, and the prognosis is very poor. Effective treatments are urgently needed.

Effective treatments are urgently needed. To investigate the effect of protruded median lobe (PML) on the perioperative, oncological, and urinary continence (UC) outcomes among patients underwent Retzius-sparing robot-assisted radical prostatectomy (RS-RARP). 231 consecutive patients who had undergone RS-RARP were collected and analyzed. Patients were divided into three groups based on the PML degree PML<5 mm (n=99); 5≤ PML <10 mm (n=91); PML ≥10 mm (n=41). The perioperative outcomes, short-term oncological, and UC outcomes were compared among the three groups. Those outcomes were also compared in patients with significant PML (>10 mm) who underwent the traditional or Retzius-sparing RARP. The median PML was significantly associated age (P<0.001) and prostate volume (P<0.001). Perioperative characteristics including console time, estimated blood loss (EBL), intraoperative transfusion rate, and complications were not statistically different among the three groups (P=0.647, 0.574, 0.231, 0.661, respectively). The rate of positive surgical margin (PSM) were not significantly different in the three groups (P=0.065). No significant difference regarding UC and biochemical recurrence (BCR) at 12-month follow-up was observed in the three groups (P>0.05). Comparison between the two approaches i
