Filter by:With advances in endourological equipment, minimally invasive procedures have been found to be sufficient for the treatment of ureteral stones in children. The investigators aimed to evaluate the stone-free rate and complications related to the procedure and to compare it with the period when their experience were limited by presenting their patients with ureteral stones treated by ureteroscopy (URS) and holmium YAG laser in the last three years after their 15-year routine endourological practice. The investigators retrospectively compared 54 cases treated with ureteroscopy (URS) for ureteral stones between 2009-2011, the first three years of our endourological interventions in children, and 78 cases treated with URS for ureteral stones between 2020-2022, the last three years of their 15-year endourological experience, from hospital records. Demographic data, stone-free rates, number of procedures and recorded complications were evaluated in both groups.
This study investigated a previously unassessed operating position for ureteroscopic holmium laser lithotripsy in patients with upper ureteral stone. The reverse Trendelenburg position can reduce migration and improve the stone free rate (SFR). Moreover, less utilization of flexible ureteroscope and hospital stay in reverse Trendelenburg position can reduce the medical cost. Therefore, it can be safely used as an optional surgical method for the treatment of upper ureteral stones.
This study aims to compare three groups of patients who underwent uncomplicated ureteroscopic lithotripsy (URSL) to evaluate whether stents could be eliminated after the procedure
Patients included in the study included the necessary tests U / A, K, Na, Cr, BUN, CBC, And U / C was checked and anesthesia counseling was done. Patients were prepared for action. The demographic and clinical data of the patients, including age, sex, size, and location of the stones were recorded. Then patients as random allocation were divided into two groups: A (control group, no basket of bases and group B (use of pneumatic synchronous buccal waist). The dividing person and the patients themselves were not aware of which group they were in. They were double-blind was. In each group, ureteroscopy was performed using a standard F9.5 ureteroscope. After reaching the rock in group A (control), the probe of the pneumatic crusher was passed through the working channel of the ureteroscope and began crushing the rock. During the crushing process, the minimum flow of water, flattening and the single-shot impact was used to minimize the stone's retropulsion. In group B (using a basket of wires3F) the helical type was passed through the four wires of the working channel of the ureteroscope and routed to the proximal part of the rock, and the stone was routed to the bowl, then the stone was ducted The gasket was kept, and the probe of the pneumatic crusher also passed through the working channel and proceeded to break it down. Conditions were observed during the stomach as the control group. Ureteroscopic crushing was performed by a urologist in both groups under similar technical conditions. Findings during and after the completion of crushing include the success, stone retropulsion or parts larger than 3 mm, which requires secondary measures (SWL - ureter stenting, resection ureteroscopy), the duration of stone breakdown and traumatic ureteric complications in both groups it is registered.
