ABSTRACT
Objective To evaluate the efficacy, advantages and shortcomings of micro-percutaneous nephrolithotomy in treatment of uncomplicated ureteral calculi.Methods Clinical data were collected from 126 patients with a failure treatment of history by ESWL (extracorporeal shock wave lithotripsy) and RIRS (retrograde intrarenal surgery) in treatment of upper ureteral calculi (< 3.0 cm) from June 2015 to May 2016. Antegrade percutaneous access was obtained by B-type ultrasound guidance. Micro-PCNL was done using YAG laser fiber or pneumatic through the ureteroscope (F4.5~F6.5、F6.0~F7.5, 315 mm) to disintegrate the stones. The calculi clearance rate, operation time, operative hemorrhage, length of hospital stay and complications of the patients were analyzed after operation.ResultsThe calculi clearance rate was 88.9%, the operation time was 15~75 min, the operative hemorrhage was 15~35 ml, the length of hospital stay was 5~10 d. Only one patient need the second stage surgery because of intraoperative hemorrhage affected the surgical ifeld. No patients occurred massive hemorrhage, pneumothorax, bowel and other complications such as organ damage.Conclusion Micro-PCNL had a good clinical curative effect and security in treatment of uncomplicated ureteral calculi, which was worthy of promoting clinically.
ABSTRACT
ObjectiveTo explore the influences of Penehyclidine Hydrochloride on [ Ca2 + ] i and the expression of cysteine-containing aspartate-specific proteases-3 (Caspase-3) in neural cells of neonatal rats after hypoxic-ischemic injury within 12 h.MethodsSeven-day-old Sprage-Dowley rats ( n =128) were randomly assigned into four groups:Sham group ( sham operation group,n =32),hypoxic-ischemic encephalopathy (HIE) group ( HIE models,n =32 ),N group ( HIE models treated with Nimodipine,n =32 ),and P group (HIE models treated with Penehyclidine Hydrocloride,n =32).Brain tissues were collected at different time points (2 h,4 h,6 h,and 12 h) after modeling.We utilized fluorescent microscope to detect the expression of Caspase-3 via making frozen slices of rat brain tissue,while [ Ca2+ ]iof neural cells in live brain slices of rats was measured by laser scanning confocal microscope.ResultsCompared with Sham group,both [ Ca2 + ] i and the expression of Caspase-3 of neural cells increased significantly ( P ＜ 0.01 ) in brain cortex in HIE group.[ Ca2 + ] i and Caspase-3 activity increased gradually with time since 2 h after making HIE models and reached a peak at the time points of 12 h ( P ＜0.05).In N group and P group,both of [ Ca2+ ]i and Caspase-3 decreased compared with HIE group (P ＜0.01 ),however,there was no significant difference between N group and P group ( P ＞ 0.05 ).In addition,[ Ca2 + ] i and Caspase-3 activity had no significant difference between 6 h and 12 h (P ＞ 0.05 ).ConclusionPenehyclidine Hydrocloride can protect the brain tissue from hypoxic-ischemic injury via relief of calcium overload and inhibition of Caspase-3 activity.
