Clinical applications of rigid dilatation using double catheters method for ureteric stenosis / 中国医师进修杂志

Objective To evaluate the clinical applications of rigid dilatation using double catheter method for ureteric stenosis.Methods The clinical data of 51 ureteric stenosis patients who had underwent rigid dilatation using double catheters method were retrospectively analyzed. Results Among the 51 patients,the ureteroscopy successfully went through the stricture in 46 cases(90.2%),and all patients had no ureteral perforation or laceration.Among the 5 patients in whom ureteroscopy did not go successfully through the stricture,2 cases were placed double J tube,2 cases underwent percutaneous nephrolithotomy,and 1 case underwent two stage ureteral stricture resection and religation.All patients were examined by ultrasound examination 3 months after the treatment,and the degree of hydronephrosis was partial remission. Conclusions The double catheters method is a safe and effective way for rigid dilatation for ureteric stenosis,and it is worth popularizing.

Single-port laparoscopic surgery for radical nephrectomy: report of 22 cases / 南方医科大学学报

<p><b>OBJECTIVE</b>[corrected] To evaluate the method and technique of single-port laparoscopic radical nephrectomy.</p><p><b>METHODS</b>Form January 2009 to September 2011, 22 patients with renal carcinoma were treated with single-port laparoscopic radical nephrectomy. An incision about 5 cm in length was made through the umbilicus or in the postaxillary line under the 12th rib to establish the peritoneal or retroperitoneal working space. A single-port cannulation was deployed and the operation was carried out using standard and crooked laparoscopic equipment.</p><p><b>RESULTS</b>The operations were completed successfully in all the 22 cases without conversion to open surgery, but additional trocar was needed in 5 cases. The mean operative time of radical nephrectomy was 150 min (90-240 min). The mean postoperative hospital stay was 7.6 days (3-15 days). The operation left a roughly 5-cm-long scar in all the cases.</p><p><b>CONCLUSION</b>Single-port laparoscopic radical nephrectomy is safe and feasible with good cosmetic effect and shows much potential in radical resection of renal carcinoma.</p>

Percutaneous nephrolithotomy for treating upper urinary calculi under local anesthesia ( report of 1363 cases) / 中华泌尿外科杂志

Objective To discuss the feasibility of percutaneous nephrolithotomy (PCNL) for treating upper urinary calculi under local anesthesia.Methods One thousand three hundred and sixty-three patients who suffered with upper urinary calculi were treated with PCNL, the puncture and tracts were created using local anesthesia and guided through ultrasound.Of the 1363 patients, 475 patients had complicated renal caluli, 520 patients had kidney pelvic calculi and 368 had upper uretere calculi.Results All of the patients successfully received PCNL under the local anesthesia.Of the 1363 patients five tracts were used in two patients, four tracts were used in four patients, three tracts were used in nine patients, double tracts were used in 25 patents and one tract was used in the remaining patients.The stone-free rate was 96.0% in the kidney pelvic calculi patients, 100.0% in the upper uretere calculi patients, and 90.1% in the complicated renal caluli patients.90.0% patients were find well throught the operation, 10.0% patients find a little pain and solved by another more 5 - 10 ml lidocaine local injection or 50 - 75 mg pethidine hydrochloride intramuscular injection.No case stop operation because of pain or position changed.All without any severe complications such as damaged of liver, spleen, thorax and intestine.Conclusion The PCNL handled under local anesthesia was simple safe and effective, deserved clinical popularizing use.
