Objective: We investigated the impact of intraoperative tumor capsule injury (TCI) during robot-assisted partial nephrectomy (RAPN) or laparoscopic partial nephrectomy (LPN) on oncological outcomes, as well as underlying factors of intraoperative TCI for improving surgical outcomes.
Methods: A total of 253 patients who underwent RAPN or LPN between 2010 and 2022 were retrospectively analyzed and were divided into two groups: non-TCI and TCI groups. The background was compared between two groups.
Background: The existing criteria for living kidney donors (LKDs)in Japan are controversial. We evaluated the roles of computed tomography volumetry (CTV) and 99 m Tc-diethylenetriamine penta-acetic acid (DTPA) scintigraphy in assessing preoperative and postoperative renal function and predicting early recovery of residual renal function.
Methods: We retrospectively reviewed the medical charts of 175 consecutive LKDs who underwent donor nephrectomy (DN) at our institution between 2006 and 2022.
: The standard recommendation for patients with non-muscle invasive bladder cancer is 5-aminolevulinic acid-mediated photodynamic diagnosis. The intensity of the fluorescence caused by the intracellular accumulation of protoporphyrin IX (PPIX) varies among tumors and patients. This study investigated the circadian rhythm of intracellular PPIX accumulation in bladder urothelial cancer cells exposed to 5-aminolevulinic acid.

Methods: We included 128 LKDs who underwent donor nephrectomy at our institution between 2006 and 2022. Clinical and radiographic data were retrospectively obtained from medical charts.
Article Synopsis
- The study aimed to evaluate how challenging laparoscopic adrenalectomy is by using the Mayo Adhesive Probability (MAP) score to assess issues with surrounding fat.
- It involved a retrospective analysis of 103 patients, categorizing them based on preoperative CT scans into high and low MAP groups, comparing clinical features and analyzing tissue samples.
- Results showed that high MAP patients were generally younger, had a higher proportion of males, and experienced significantly more blood loss during surgery, indicating a need for careful management in these cases.
