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 investigate the clinical effect of retroperitoneal laparoscopic dismembered pyeloplasty on ureteropelvic junction obstruction (UPJO). Methods From November 2010 to September 2015, a total of 28 cases (21 males and 7 females) with ureteropelvic junction obstruction (UPJO) underwent retroperitoneal laparoscopic dismembered pyeloplasty. All the 28 patients had a previous history of different degrees of lumbar pain, which was confirmed as typical UPJO by imaging examination. Operation method: following complete renal pelvis and upper ureter isolation, the renal pelvis was clipped into a trumpet-shaped mouth, 1/3 of the upper renal pelvis was temporarily kept without section. In the inferior margin of renal pelvis, longitudinal cut procedure was operated in the ureter and across the stenotic segment in about 1–2 cm; and then, anastomosis of the ureter and the renal pelvis at the lowest was performed, to maintain the continuity of the renal pelvis and ureter. Subsequently, the stenosed segment of ureter and the dilatant renal pelvis were removed, the posterior ureteropelvic anastomosis was made with an interrupted suture, and antegrade stenting of double J tube was further performed, followed by a continuous suture of the anterior wall. Results The procedure was successfully accomplished in all patients whithout conversion to open surgery. The operating time was 90-240 minutes with the median time of 160 minutes. The estimated blood loss was 20-70 mL with the median of 50 mL. No severe surgical complication occurred in perioperative period. The 3-24 -month follow up showed that symptoms of lumbar pain were relieved or disappeared in all the incorporated patients. Postoperative radiographic examination showed no stomal stenosis at the ureteropelvic junction, and the hydronephrosis was alleviated. Conclusions Retroperitoneal laparoscopic dismembered pyeloplasty for UPJO is an effective, safe, and minimally invasive surgical technique. The key to the success of the operation is to the accurate renal pelvis clipping, tension- and torsion-free anastomosis of the lowest position of the renal pelvis and the ureter, and the reconstruction of a new funnel-shaped ureteropelvic junction.
ObjectiveTo analyze the related risk factors for catheter-associated urinary tract infection in the Intensive Care Unit (ICU), and make corresponding nursing countermeasures. MethodsBy target monitoring of catheter-associated urinary tract infection in 184 patients in the ICU from 2011 to 2012, infection risk factors were analyzed. The measures of nursing interventions had been taken since January 2012, and the effects before and after the intervention were contrasted and evaluated. ResultsBefore the intervention, 951 out of 1 229 patients in 2011 had indwelling catheter, and catheter-associated urinary tract infection occurred in 127 patients with an infection rate of 13.35%. After the intervention, 841 out of 1 437 in 2012 had indwelling catheter, and catheter-associated urinary tract infection occurred in 57 patients with an infection rate of 6.78%. ConclusionTaking effective intervention measures can effectively reduce the ICU catheter-associated urinary tract infection and it also ensures the safety of medical care.
