RÉSUMÉ

Objective To investigate the safety and efficacy of ureteral access sheath (UAS) with vacullm suction during flexible ureteroscopy lithotripsy in treatment of renal stones. Methods 96 cases of renal stones patients who received flexible ureteroscopy lithotripsy were retrospectively analyzed and divided into two groups:control group with 50 cases and treatment group with 46 cases. The stones free rate, operation time, intrapelvic pressure, renal colic, formation of steinstrasse, SIRS, Calcitonin Zymogen, leukocyte count, hospitalization time, hospitalization costs and treatment efficiency were evaluated after one month. Results The average, maximum and minimum intrapelvic pressure of treatment group was much lower than that of control group (P < 0.05); After one month, the treatment efficiency and stones free rate of control group was 70.0% and 82.0%, lower than that of treatment group (P < 0.05); The operation time of control group and treatment group was(108.6 ± 3.5) min, (86.3 ± 5.2) min (P < 0.05); The cases of renal colic, steinstrasse and SIRS of control group after treatment was 13 cases, 11 cases, 10 cases which was more than that of treatment group with 2 cases respectively (P < 0.05); The hospitalization time, hospitalization costs of control group and treatment group was (8.8 ± 1.1) d, (23 067.5 ± 392.8) RMB and (7.7 ± 1.2) d, (21 957.3 ± 378.6) RMB (P < 0.05); The Calcitonin Zymogen, leukocyte count of control group and treatment group was (1.5 ± 0.3) and (0.3 ± 0.1) ng/ml, (14.6 ± 0.5)×109/L and (6.4 ± 0.6)×109/L (P < 0.05). Conclusion The application of ureteral access sheath with vacullm suction during flexible ureteroscopy lithotripsy in treatment of renal stones was simple, safe and effective, and can shorten the operation time, improve the rate of clearing stone and treatment efficiency, reduce the incidence of adverse reactions. The application can be extended.

RÉSUMÉ

<p><b>OBJECTIVE</b>To explore the feasibility of laparoscopic-assisted radical right hemicolectomy with the outcome being a complete mesocolic excision (CME).</p><p><b>METHODS</b>Between February 2010 and June 2011, we performed the standardized surgery of laparoscopic-assisted radical right hemicolectomy with an aim of CME on 14 patients. There were 10 males and 4 females, with an average age of 57 years (range 36 to 74 years). All the pathologic results in 14 cases were primary colonic adenocarcinoma. The TNM stages were distributed as follows: 2 in II A, 3 in II B, 3 in III A, 5 in III B and 1 in III C.</p><p><b>RESULTS</b>Surgery was successfully performed for all patients without open conversion. The average operation time was (178 ± 37) minutes (range 127 to 221 minutes), average intraoperative blood loss was (67 ± 23) ml (range 30 to 110 ml), while the average number of lymph node harvest was 21 ± 7 (range 14 to 31), and the postoperative hospital stay was (10.0 ± 2.2) days (range 7 to 15 days). Minor complications occured in 2 patients. Major complications and post-operative mortality were not observed. All the patients were followed up for 3 to 19 months, no tumor recurrence or metastasis was identified.</p><p><b>CONCLUSION</b>The standardized surgery of laparoscopic-assisted radical right hemicolectomy with the final outcome of CME is safe and feasible.</p>
