    We evaluated and described the impact of prostatic indocyanine green (ICG) injection on extended pelvic lymph node (LN) dissection (ePLND) in robotic-assisted radical prostatectomy (RARP). Between January 2019 and December 2021, we included consecutive 50 PCa patients who underwent ePLND during RARP with (n = 25) or without (n = 25) prostatic ICG injection. ICG injection was performed during abdominal port placement and robot docking. Pelvic LNs reflecting green color were initially excised and then the template was completed. The outcomes of two groups were compared. Overall, nine (36%) and five (20%) of the patients had metastatic LN involvement in the ICG and non-ICG groups, respectively. Of the 509 dissected LNs in the ICG group, 122 (23.9%) were fluorescence active. 20 LNs (3.9%) were metastatic in this group, 9 (45%) of which were ICG+. 408 LNs were resected on the non-ICG group with 8(1.9%) being metastatic. Eight (88.9%) of nine pN+ patients were florescent positive in the ICG group. Out of six patients with pN+ disease, Ga68 PSMA-PET/CT detected positive LNs preoperatively. In addition to preoperative Ga68 PSMA-PET/CT investigation, ICG-guided ePLND might increase identification and removal of metastatic LNs duirng RARP. Improvements in staging and oncologic outcomes may also be seen in intermediate- and high-risk patients.

    Effect of the ureteral access sheath size on acute kidney injury biomarkers in retrograde intrarenal surgery: a prospective, randomized study
    (Karger Publishers, 2023) Balcı, Melih; Kılınçkaya, Muhammed Fevzi; Akdemir, Serkan; Şenel, Cağdaş; Güzel, Özer; Aslan, Yılmaz; Turhan, Turan; Arslan, Murat; Güneri, Çağrı; Tuncel, Altuğ; N/A; Aykanat, İbrahim Can; Doctor; N/A; Koç University Hospital; N/A
    Introduction: the aim of the study was to investigate the effect of the diameter of the ureteral access sheath (UAS) used during RIRS on kidney injury based on acute kidney injury (AKI) biomarkers. Methods: this prospectively randomized controlled study included a total of 125 patients divided into three groups: group 1 (n = 52) in which a 12/14 Fr UAS was used, group 2 (n = 52) in which a 9.5/11.5 Fr UAS was used, and group 3 (n = 21) that was designed as the control group with no urogenital disease history. Urine samples were collected preoperatively and at the postoperative second and 24th hours after surgery and analyzed for AKI using the urinary kidney injury molecule-1 (uKIM-1), N-acetyl-ß-D-glucosaminidase, and neutrophil gelatinase-associated lipocain biomarkers. Results: in group 1, there was no statistical change in any of the three AKI biomarkers at the postoperative second or 24th hour compared to the preoperative period. In group 2, the values of all three AKI biomarkers were statistically significantly increased at the postoperative second and 24th hours compared to the preoperative period while no statistical difference was observed between the two postoperative evaluation times. At the postoperative second hour, the uKIM-1 value was statistically significantly higher in group 2 compared to group 1 (p = 0.043). Conclusions: the results of our study showed that AKI was not observed in RIRS performed with a 12/14 Fr UAS while the use of a 9.5/11.5 Fr UAS resulted in AKI according to the assessment of the related biomarkers.
