ABSTRACT

OBJECTIVE@#To compare the safety and effectiveness of active migration technique and in situ lithotripsy technique in the treatment of 1-2 cm upper ureteral calculi by retrograde flexible ureteroscopy.@*METHODS@#A total of 90 patients with 1-2 cm upper ureteral calculi treated in the urology department of Beijing Friendship Hospital from August 2018 to August 2020 were selected as the subjects. The patients were divided into two groups using random number table: 45 patients in group A were treated with in situ lithotripsy and 45 patients in group B were treated with active migration technique. The active migration technique was to reposition the stones in the renal calyces convenient for lithotripsy with the help of body position change, water flow scouring, laser impact or basket displacement, and then conduct laser lithotripsy and stone extraction. The data of the patients before and after operation were collected and statistically analyzed.@*RESULTS@#The age of the patients in group A was (51.6±14.1) years, including 34 males and 11 females. The stone diameter was (1.48±0.24) cm, and the stone density was (897.8±175.9) Hu. The stones were located on the left in 26 cases and on the right in 19 cases. There were 8 cases with no hydronephrosis, 20 cases with grade Ⅰ hydronephrosis, 11 cases with grade Ⅱ hydronephrosis, and 6 cases with grade Ⅲ hydronephrosis. The age of the patients in group B was (51.8±13.7) years, including 30 males and 15 females. The stone diameter was (1.52±0.22) cm, and the stone density was (964.6±214.2) Hu. The stones were located on the left in 22 cases and on the right in 23 cases. There were 10 cases with no hydronephrosis, 23 cases with grade Ⅰ hydronephrosis, 8 cases with grade Ⅱ hydronephrosis, and 4 cases with grade Ⅲ hydronephrosis. There was no significant diffe-rence in general parameters and stone indexes between the two groups. The operation time of group A was (67.1±16.9) min and the lithotripsy time was (38.0±13.2) min. The operation time of group B was (72.2±14.8) min and the lithotripsy time was (40.6±12.6) min. There was no significant difference between the two groups. Four weeks after operation, the stone-free rate in group A was 86.7%, and in group B was 97.8%. There was no significant difference between the two groups. In terms of complications, 25 cases of hematuria, 16 cases of pain, 10 cases of bladder spasm and 4 cases of mild fever occurred in group A. There were 22 cases of hematuria, 13 cases of pain, 12 cases of bladder spasm and 2 cases of mild fever in group B. There was no significant difference between the two groups.@*CONCLUSION@#Active migration technique is safe and effective in the treatment of 1-2 cm upper ureteral calculi.

ABSTRACT

Objective To evaluate the quality of blood after marine storage and transportation,to establish a quantitative energy metabolism platform supported by extracellular flux(XF)technique to determine the glycolysis level of red blood cells(RBC), and to introduce the "functional dose", as a valuable supplement, into the quality evaluation of RBCs after marine storage and transportation.Methods The extracellular acidification rate(ECAR)of erythrocyte glycolysis was detected by XF.The levels of glycolysis, ATP contents and free hemoglobin of RBCs were detected before and after marine navigation.RBC suspensions stored at 4℃in a blood bank on land served as control.Results The results showed that the glycolysis level of RBCs was detected by XF.Indicators of blood quality and energy metabolism of RBCs were detected in the twice marine storage and transportation.Blood samples transported around the Gulf of Bohai had no significant change,indicating that the samples were well preserved.The energy indicators of blood samples navigated in the Pacific Ocean decreased significantly,and it was recommended that the samples be discarded.Conclusion XF technique has been applied to the measurement of erythrocyte glycolysis,enabling high-throughput and multi-indicator dynamic detection of viable cells.The energy metabolism of erythrocyte should be recommended as an important indicator for evaluating blood after marine storage and transportation.
