Background: The indications for nephron-sparing surgery have been considerably extended by guideline recommendations in recent years. It remains unclear whether clinical practice still reflects these new guidelines.
Objective: In this retrospective, monocentric analysis at a tertiary referral center the indications for partial nephrectomy over a 13-year period were evaluated.
Methods: In a retrospective database analysis all cases of surgically treated renal masses from 2001 to 2013 were evaluated. Besides demographic, tumor-specific and perioperative variables the development of the surgical technique depending on the tumor stage was evaluated.
Results And Discussion: The proportion of nephron-sparing surgery cases increased from below 20 % in 2001 to 35 % in 2013 in the entire cohort. For stage T1a tumors, partial nephrectomy increased from approximately 50 % to over 90 % and for T1b tumors it rose from 10 % to 50 %. Logistic regression revealed stage 1 tumors to be predictive of partial nephrectomy over the complete evaluation period. Extending the indications for partial nephrectomy even to higher stages is under discussion but not yet supported by data from prospective, controlled studies.

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.

Purpose: The incidence of renal cell carcinoma has been steadily increasing over the past two decades, raising the need for minimally invasive approaches. We sought to present the methodology of the percutaneous cryoablation (PCA) procedure developed based on one year of experience with 81 PCA procedures.
Material And Methods: The percutaneous cryoablation programme at Wroclaw Medical University Hospital has been successfully operating for a year.
Impact of thermal denaturation on renal volume reduction after partial nephrectomy using soft coagulation hemostasis.

Department of Urology, NTT Medical Center Tokyo, 5-9-22 Higashigotanda, Shinagawa-ku, Tokyo, 141-8625, Japan.
Partial nephrectomy has become the gold standard treatment for small renal masses. This study aimed to assess the impact of soft coagulation hemostasis on parenchymal volume reduction of the operated kidney after an open partial nephrectomy. We retrospectively reviewed 94 patients with small renal tumors who underwent open partial nephrectomy with soft-coagulation hemostasis at our institution.
