摘要:目的:探讨后腹腔镜输尿管切开取石术治疗嵌顿性输尿管结石的临床价值和技术要点。 方法:2006年12月至 2009年3月,对58例嵌顿性输尿管中上段结石采用后腹腔镜输尿管切开取石术,术中取石后于镜下直接置入双J管,间段缝合输尿管切口。 结果:58例手术均获成功,无中转开放手术,结石清除率100%。术后创腔引流液量少,3～5d拔除引流管,1周出院,术后3周膀胱镜下拔除双J管。随访1～27个月,B超复查显示肾积水明显好转或消失,无结石复发。 结论:后腹腔镜输尿管切开取石术治疗嵌顿性输尿管结石具有创伤小\疗效好、术后恢复快等特点,明显优于开放手术及其它手术,值得推广应用。Abstract: Objective: To summarize our experience and evaluate the outcome of retroperitoneal laparoscopic ureterolithotomy of the upper ureter impacted stone. Methods: Between December 2006 and March 2009, 58 patients underwent retroperitoneal laparoscopic ureterolithotomy of the upper ureter. After removal of the stones, the double J was put in and interrupted suture was performed for upper ureter. Results: Retroperitoneoscopic ureterolithotomy was successful in all patients, there was neither ureteral stricture nor recurrent calculus, the blood loss ranged from 510 mL, without urine leakage occurred.The mean hospital stay was 7 days, after 3 weeks double J was removed by cystoscopy. With 127 months followup, the hydronephrosis relieved and no recurrence of ureter calculus founded. Conclusion:Retroperitoneoscopic ureterolithotomy is a safe and effective minimally invasive operation, and worth to generalization.
Objective To evaluate the clinical value of ureteroscope in cholelithiasis treated by laparoscopic surgery. Methods The clinical data of 36 patients admitted because of hepatolithus with ureteroscope combination in laparoscopic surgery from February 2007 to September 2009 in Guidong People’s Hospital of Guangxi were analyzed retrospectively. Results In 33 cases, stones were removed once by ureteroscope in laparoscopic surgery with residual stones (in 3 cases residual stone were removed secondarily through T tube) and the other 3 cases were transferred to laparotomy forcedly due to bleeding of biliary duct and vessels of porta hepatis and tearing of bile duct. During operation, blood loss was 30-280 (94.51±54.70) ml; operation time was 110-260 (147.22±48.45) min; recovery time of bowel movement was 1-3 (2.03±0.76) d; postoperative hospitalization time was 6-13 (7.12±1.65) d (some discharged with T tube); the time of patients of T tubes pulled out was 28-45 (38.92±6.52) d. Bile leakage happened in 1 case and infection of biliary tract in 1 case, no complications such as biliary stricture or bile duct bleeding were found after operation. Conclusions Treatment of intrahepatic bile duct or a single extra-hepatic sand-like stones with ureteroscopy usage in laparoscopic surgery is feasible and less invasive. It is a minimally invasive treatment for intra- or extra-hepatic stones due to rapidly postoperative rehabilitation.
Objective To compare the therapeutic effect of new “One-Stitch” ureterovesical anastomosis to that of the classic Lich-Gregoir method. Methods From January 2002 to December 2004, 445 patients suffering from uremia due to chronic nephritis were treated with renal transplantation. Among them, 121 patients were operated with our new modified ureteroneocystostomy technique (the new One-Stitch group), and 324 patients were operated with Lich-Gregoir technique (the Lich-Gregoir group). In the new One-Stitch group, there were 79 males and 42 females, aged 20-62 years (35.7 years on average). The course of the disease was 2-11 years (2.7 years on average). In the Lich-Gregoir group, there were 211 males and 113 females, aged 19-65 years (33.9 years on average). The disease course was 1-14 years (2.3 years on average). There was no significant difference between the two groups in age, proportion of genders, primary diseases and course of the disease (P gt; 0.05). The operative time, the ureteral compl ications and non-ureteral compl ications were compared between the two groups after the renal transplantation. Results The operative time for the new One-Stitch and Lich-Gregoir techniques was (8.7 ± 1.1) minutes and (22.4 ± 5.1) minutes, indicating the difference was significant (P lt; 0.05). All recipients were followed up for 3-5 years. In the new One-Stitch group, there were 5 patients with leakage of urine, 15 with gross hematuria, 4 with ureteral obstruction and 28 with urinary system infection. Symptomatic vesicoureteral reflux and stone formation were not observed in this group. In the Lich-Gregoir group, there were 17 patients with leakage of urine, 12 with gross hematuria, 13 with ureteral obstruction, 86 with urinary system infection, 6 with symptomatic vesicoureteral reflux and 2 with stones. In the new One-Stitch group, the incidence rate of compl ications of gross hematuria was 12.4%, which was significantly different from 3.7% in the Lich-Gregoir group (P lt; 0.05). The incidence rates of ureteral compl ications in the Lich-Gregoir and the new One-Stitch groups were 19.8% and 15.4%, respectively. The difference was not significant (P gt; 0.05). There was no significant difference between the two groupsin incidence rate of urinary system infection, delayed recovery of kidney function after kidney transplantation and rejectionreaction (P gt; 0.05). Conclusion The new One-Stitch group has no significant difference in ureteral compl ications ompared with the Lich-Gregoir group, and has become a preferential ureterovesical reimplantation technique because of its simple and has convenient operation.
ObjectiveTo analyze the causes and potential risk factors of re-catheterization after failure of no urinary catheter in patients undergoing lung cancer surgery.MethodsThe clinical data of 1 618 patients without urinary catheter indwelling during the perioperative period of thoracic surgery in our hospital from 2013 to 2019 were retrospectively analyzed, including 791 males and 827 females, with a median age of 58 years, ranging from 27 to 85 years. And the risk factors for re-insertion after failure of urinary catheter were investgated.ResultsThe rate of catheter re-insertion was 1.5% (24/1 618). Compared with patients without re-insertion, patients with re-insertion had longer operation time [120.0 (95.0, 130.0) min vs. 120.0 (115.0, 180.0) min, P=0.015] and more intraoperative fluid infusion [800.0 (600.0, 1 100.0) mL vs. 1 150.0 (725.0, 1 350.0) mL, P=0.008]. Further multivariate analysis found that the operation time (OR=1.014, P=0.004, 95%CI 1.005-1.024) and intraoperative fluid infusion (OR=1.001, P=0.022, 95%CI 1.001–1.002) were independent risk factors for re-insertion.ConclusionThe rate of catheter re-insertion in lung cancer patients is relatively low, and conventional no placement of catheter is safe and feasible after lung cancer surgery. Increasing operation time or intraoperative infusion volume may increase the risk of catheter re-insertion after lung cancer surgery.

Objective To investigate the safety and feasibility of preoperative non-indwelling catheter in primary unilateral total knee arthroplasty (TKA) without tourniquet . Methods From January 2016 to January 2017, a total of 60 patients undergoing primary unilateral TKA surgery were randomly divided into preoperative non-indwelling catheter group (group NIC, n=30) and indwelling catheter group (group IC, n=30) . The patients in group NIC were not retained catherter, and the patients in group IC were retained catherter. All patients did not use tourniquet. The time of first urination, the volume of first urination, and the occurrence of urine retention, urinary irritation symptoms and urinary tract infection of patients in two groups were analyzed. The incidence of venous thrombosis of the lower extremity was also recorded. Results There were statistical differences (P<0.05) between group NIC and group IC in the time of first urination [(3.2±0.6) vs. (4.5±1.8) hours] and urine volume [(262.5±29.4) vs. (391.6±50.2) mL], but there was no significant difference (P>0.05) between the two groups in urinary retention (6.7% vs. 16.7%), urinary tract irritation (33.3% vs. 23.3%), or urinary tract infection (0.0% vs. 16.7%). Conclusion Preoperative non-indwelling catheter in primary unilateral TKA without tourniquet is safe and feasible.
