Objective: Creation of the access tract is an important step in percutaneous nephrolithotomy (PNL). In this study, we compared the efficiency and safety of Amplatz, Alken, and balloon dilation methods in the creation of the access tract.
Materials And Methods: Data from 487 PNL patients admitted to 517 renal units in 3 centers were analyzed. The Amplatz (280 patients), Alken (142 patients), and balloon (95 patients) dilation methods were compared for their success, duration of the dilation, injury to the collecting system, durations of fluoroscopy and surgery, stone-free and complication rates, pre- and postoperative hematocrit levels, and need for blood transfusion.
Results: The dilation methods did not significantly differ with respect to patient demographic data, mean stone area, decrease in hematocrit, need for blood transfusion, unsuccessful tract dilation, injury to the collecting system, stone-free rate, and rate of postoperative complications. The mean fluoroscopy times during Amplatz, Alken, and balloon dilation were 288.52 ± 164.67, 287.34 ± 164.99, and 169.23 ± 21 seconds, respectively. The mean duration of surgery was 96.48 ± 46.07, 94.72 ± 42.25, and 78 ± 25.96 minutes, respectively. The duration of tract creation was 328.67 ± 172.99, 325.14 ± 175.70, and 203.50 ± 32.76 seconds, respectively. The durations of surgery and tract creation were significantly shorter in the balloon dilation group.
Conclusion: None of the dilation methods was significantly superior in terms of surgical success, efficiency, or safety. Although balloon dilation was advantageous with respect to time parameters, the role of surgical experience should not be ignored.

Background: It has been recognized that the type of anesthetic and analgesic technique and the relative pain degree may have an influence on hyperglycemic-stress response to surgery. This comparative study aimed to assess glucose levels in both mothers and infants during normal vaginal delivery. This study aimed to investigate this stress response between mothers who received parenteral analgesia versus epidural analgesia (EA) as an objective reflection for pain response.

Objective: To describe the treatment outcomes of patients who underwent Percutaneous Transluminal Angioplasty (PTA) for Central Vein Occlusive Disease (CVOD) in end-stage kidney disease and determine the association between patient profile and treatment outcomes.
Methods: A single-institution, retrospective review of patients aged 18 and above with end-stage kidney disease who underwent PTA for CVOD in the University of the Philippines - Philippine General Hospital (UP-PGH) from January 1, 2013, to December 31, 2022, was performed. These patients' demographic and clinical profiles were evaluated using means, frequencies, and percentages.

Background: Cervical cancer is a prevalent malignancy among women, often asymptomatic in early stages, complicating detection.
Objective: This study aims to investigate innovative techniques for early cervical cancer detection using a novel U-RCNNS model.
Methods: Cervical epithelial cell images stained with hematoxylin and eosin (HE) were analyzed using the U-RCNNS model, which integrates U-Net for segmentation and R-CNN for object detection, incorporating dilated convolution techniques.
