Purpose:
To evaluate whether using flexible and navigable suction ureteral access sheath can obviate insertion of double J stent and establish the safety of overnight ureteric catheter placement as alternative following flexible ureteroscopy for kidney stones.
Materials and Methods:
Five hundred forty adults were prospectively enrolled across 25 centers (from April 2023 to January 2024). Patients were divided into group 1 (overnight ureteric catheter), and group 2 (double J stent). Surgeons could choose either modality as per their discretion. One-to-one propensity score-matching for age, sex, pre-stenting, Hounsfield units, stone volume and location was performed. Thirty-day computed tomography scan was done to estimate stone-free status.
Results:
After matching, 120 patients were included in each group. Group 1 had significantly shorter lasing, ureteroscopy, surgical time. Median day 1 loin pain score was similar (1 [1, 2] in both groups). Median postoperative stay was shorter in group 1 (0 days [0, 1] vs. 1 day [0, 2], p<0.001). One patient in group 2 required a blood transfusion. Incidence of fever was similar (5.0% vs. 0.8%).Loin/abdominal pain requiring medication occurred in one patient in group 2. Stent-related symptoms occurred in 2 patients in group 1. Three patients (2.5%) in group 1 and 2 patients (1.7%) in group 2 required readmission. Thirty-day stone-free status was higher in group 1 patients (79.2% vs. 56.7%).
Conclusions
In selected patients after thorough inspection to ensure no injury or residual fragments remain, placing an overnight ureteric catheter can be a safe alternative to a double J stent.

Objective:
To evaluate the effect of adding DPP4 inhibitor (DPP4-i) on glycemic variability (GV) in patients with type 2 diabetes mellitus (T2DM) treated with premixed human insulin (MHI).
Methodology:
We conducted a prospective study in patients with T2DM on twice-daily MHI with or without metformin therapy. Blinded continuous glucose monitoring was performed at baseline and following 6 weeks of Vildagliptin therapy.
Results:
Twelve patients with mean (SD) age of 55.8 (13.1) years and duration of disease of 14.0 (6.6) years were recruited. The addition of Vildagliptin significantly reduced GV indices (mmol/L): SD from 2.73 (IQR 2.12-3.66) to 2.11 (1.76-2.55), p=0.015; mean amplitude of glycemic excursions (MAGE) 6.94(2.61) to 5.72 (1.87), p=0.018 and CV 34.05 (8.76) to 28.19 (5.36), p=0.010. In addition, % time in range (3.9-10 mmol/l) improved from 61.17 (20.50) to 79.67 (15.33)%, p=0.001; % time above range reduced from 32.92 (23.99) to 18.50 (15.62)%, p=0.016; with reduction in AUC for hyperglycemia from 1.24 (1.31) to 0.47 (0.71) mmol/day, p=0.015. Hypoglycemic events were infrequent and the reduction in time below range and AUC for hypoglycemia did not reach statistical significance.
Conclusion
The addition of DPP4-I to commonly prescribed twice-daily MHI in patients with T2DM improves GV and warrants further exploration.
