Purpose: We evaluated the incidence of perioperative complications after robotic partial nephrectomy.
Materials And Methods: We retrospectively reviewed the records of patients treated with robotic assisted partial nephrectomy across the 4 participating institutions. Demographic, blood loss, warm ischemia time, and intraoperative and postoperative complication data were collected. All complications were graded according to the Clavien classification system.
Results: A total of 450 consecutive robotic assisted partial nephrectomies were done between June 2006 and May 2009. Overall 71 patients (15.8%) had a complication, including intraoperative and postoperative complications in 8 (1.8%) and 65 (14.4%), respectively. Hemorrhage developed in 2 patients (0.2%) intraoperatively and in 22 (4.9%) postoperatively. Seven patients (1.6%) had urine leakage. As classified by the Clavien system, complications were grade I-II in 76.1% of cases and grade III-IV in 23.9%. Robotic assisted partial nephrectomy was converted to open or conventional laparoscopic surgery in 3 patients (0.7%) and to radical nephrectomy in 7 (1.6%). There were no deaths.
Conclusions: Current data indicate that robotic assisted partial nephrectomy is safe. Most postoperative complications are Clavien grade I or II, or can be managed conservatively.

Transperitoneal robot-assisted partial nephrectomy: a comparison of operative and oncological outcomes between posterior and anterolateral tumours.

Objective: To compare operative and oncological outcomes, as well as the risk of postoperative complications in patients who underwent transperitoneal robot-assisted partial nephrectomy (RAPN) for renal tumours located either posteriorly or anterolaterally.
Methods: Retrospective, consecutive study including 451 patients who underwent transperitoneal RAPN for non-metastatic, localised renal tumours from May 2016 to April 2023. Operative data included duration of the procedure, warm ischaemia time, and blood loss; oncological data included surgical margins and recurrence; and 90-day postoperative complications were classified according to the Clavien-Dindo classification.

Article Synopsis
- The study evaluates parenchymal volume analysis (PVA) as a potential alternative to nuclear renal scan (NRS) for assessing split renal function (SRF) before and after partial nephrectomy (PN) with warm ischemia.
- Preoperatively, PVA showed a strong correlation with NRS findings, indicating its reliability for SRF assessment (49.4% vs. 50.0%, P = .501).
- Results suggest that while PVA is consistent with NRS preoperatively, the efficacy of PVA remains uncertain for post-operative SRF evaluation after PN, indicating a need for further investigation.

Background: To compare the clinicopathological, perioperative, functional, and oncological outcomes of completely endophytic renal cell carcinoma (RCC) patients who underwent partial nephrectomy (PN) with or without preoperative hyperaccuracy CT three-dimensional (HACT3D) reconstruction.
Methods: A retrospective cohort study was conducted on 154 completely endophytic RCC patients treated with PN at our medical center from January 2018 to December 2023. Patients were divided into two groups based on whether they received preoperative HACT3D reconstruction.
Cold agglutinin syndrome as a precursor for the diagnosis of low‑grade lymphoma: A case report.

Department of Hematology, Dokuz Eylul University Hospital, Izmir 35000, Turkey.
Cold agglutinin syndrome is a form of acquired hemolytic anemia that typically arises from underlying conditions, such as infections, autoimmune disorders or lymphoid malignancies. The majority of patients remain asymptomatic and are diagnosed with anemia through routine complete blood count (CBC) testing. The present study describes the case of a male patient in his 50s who sought a second opinion at the authors' clinic due to newly detected anemia.
