Objective: To evaluate the outcomes of bilateral pretransplant nephrectomy (BPN) for small kidneys, using a bilateral dorsal lumbotomy (BDL) or transperitoneal laparoscopy (TL) approach.
Patients And Methods: Fifty-eight patients with end-stage renal disease and small kidneys underwent BPN for various indications, most commonly uncontrolled hypertension. There were 38 patients in the BDL group (group 1) and 20 in the TL group (group 2). The variables before and during surgery, and the outcomes afterward, were compared between the groups.
Results: The mean age of the patients and male/female ratio were comparable in both groups. The mean size of the kidneys removed were 7.4 and 8.2 cm, respectively, in groups 1 and 2. The mean (range) operative duration was longer in group 2, at 210 (160-240) min, than in group 1, at 112 (90-150) min (P < 0.001). The postoperative analgesic requirement for pain, blood transfusion rate, wound and pulmonary complications were similar between the groups. Bowel function recovered earlier in group 1 than group 2 (19 vs 37 h, P < 0.001). The total cost for the nephrectomy in group 2 was 3.5 times that of group 1. The mean interval between nephrectomy and transplantation was similar in both groups.
Conclusion: BDL appears to be better than TL for BPN in small kidneys because the surgery is quicker, and there is earlier bowel recovery and lower costs.

Background/aim: Immune checkpoint blockade has achieved great success as a targeted immunotherapy for solid cancers. However, small molecules that inhibit programmed death 1/programmed death ligand 1 (PD-1/PD-L1) binding are still being developed and have several advantages, such as high bioavailability. Previously, we reported a novel PD-1/PD-L1-inhibiting small compound, SCL-1, which showed potent antitumor effects on PD-L1 tumors.

Objective: To characterize early physiologic stresses imposed by surgery by applying metabolomic analyses to deeply phenotype pre- and postoperative plasma and urine of patients undergoing elective surgical procedures.
Background: Patients experience perioperative stress through depletion of metabolic fuels. Bowel stasis or injury might allow more microbiome-derived uremic toxins to enter the blood, while the liver and kidney are simultaneously clearing analgesic and anesthetic drugs.

Automated segmentation and detection of tumors in CT scans of the liver and kidney have a significant potential in assisting clinicians with cancer diagnosis and treatment planning. However, current approaches, including state-of-the-art deep learning ones, still face many challenges. Many tumors are not detected by these approaches when tested on public datasets for tumor detection and segmentation such as the Kidney Tumor Segmentation Challenge (KiTS) and the Liver tumor segmentation challenge (LiTS).

Radiation therapy is crucial for cancer treatment, but it often causes tissue damage. The kidney, which is sensitive to radiation, is under-researched in this context. This study aimed to develop a mouse model for radiation-induced acute kidney injury (AKI) using a small animal radiation research platform (SARRP) to mimic clinical radiation conditions.

Background: Below adequate health literacy is common and linked to increased risk of adverse health outcomes. Supporting optimal health following kidney transplantation requires the capacity to understand health information and make decisions about care. The impact of low health literacy in the context of pediatric kidney transplant has not previously been studied.
