Background: The objective of this study was to determine factors associated with the postoperative development of chronic kidney disease (CKD) following partial nephrectomy.
Patients And Methods: This study included 109 patients with normal renal function treated with partial nephrectomy for small renal tumors. Of these, 73 and 36 patients underwent open partial nephrectomy (OPN) and laparoscopic partial nephrectomy (LPN), respectively.
Results: Among several parameters, there was a significant difference only in the ischemia time between the OPN and LPN groups. During the median observation period of 53.4 months, CKD, defined as estimated glomerular filtration rate (eGFR) less than 60 ml/min/1.73 m(2), developed in 29 (39.7%) and 14 (38.9%) patients in the OPN and LPN groups, respectively. Univariate analysis identified age at surgery, diabetes and preoperative eGFR as significant predictors of the postoperative development of CKD; however, only age at surgery and preoperative eGFR appeared to be independently related to CKD-free survival. In fact, there was a significant difference in the CKD-free survival between patients without any independent risk factor and those with at least one of these independent risk factors.
Conclusions: Careful management following partial nephrectomy is necessary for elderly patients and/or those with impaired renal function, even mild, before surgery.

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.

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.

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.

Objectives: To examine critical care therapy rates after cytoreductive nephrectomy in metastatic kidney cancer patients.
Design, Setting, And Patients: Relying on the National Inpatient Sample (2000-2019), we addressed critical care therapy use (total parenteral nutrition, invasive mechanical ventilation, renal replacement therapy, percutaneous endoscopic gastrostomy tube insertion, and tracheostomy) and in-hospital mortality in surgically treated metastatic kidney cancer patients. Estimated annual percentage changes and multivariable logistic regression models were fitted.
