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.

Objective To observe the clinical effect and comfortable degree of the mode of super hair removal. Methods The mode of super hair removal was used to depilate the hair nearby the hair line, cheeks, upper lip, beard, ventrum, areola of breast, axillary cavity, extremities, bikini area and so on. The total number of sites was 1 000. Some sites that were especially susceptible to pain, for example, upper lip and buccal region, were smeared with compound lidocaine cream for 1 hour at least before treatment. Results Hairs in the areas of extremities, ventrum, back and axillary cavity generally needed 4 to 5 times to eradicate, and the patients had no evident discomfortableness; hairs near to the upper lip and lower mandible generally needed 5 to 7 times to reach the effect which the patient was content, and anesthetics was indispensable, or the patients would present discomfortableness. Conclusions The mode of super hair removal is more effective, quicker and more comfortable in comparison with conventional methods. Therefore, it deserves to be spread.

OBJECTIVETo construct three-dimensional (3D) models of renal stones and perform percutaneous nephrolithotomy (PCNL) virtual surgery simulation. Methods CT images were obtained from 8 patients with renal stones. Images segmentation and reconstruction were performed using MIMICS 10.0 software to construct the 3D model of the renal stones, which provided the anatomical relationships between the kidney and the adjacent organs. The optimal PCNL virtual surgery simulation for each individual case was performed using FreeForm Modeling System on the basis of the 3D model.

RESULTSEight 3D models of renal stone were constructed. The 3D model of the renal stones represented the interrelationships of the stones, intrarenal vessel, and the collecting system with the adjacent anatomical structures. Individualized PCNL virtual surgery simulations including percutaneous puncture, dilatation and pneumatic lithotripsy were performed successfully in all the 8 3D models.

CONCLUSIONDigital 3D model of renal stone provides the reliable and comprehensive imaging information for surgical design, and PCNL virtual surgery simulation has important clinical significance to improve the stone clearance rate and reduce the surgical complications.

Lipoma is the most common superficial benign tumor in clinical practice. Generally, lipoma is small in size. Giant lipoma is not common, and giant lipoma in tendon sheath is rare. We reports a case of axillary subcutaneous lipoma and giant lipoma in the tendon sheath. The preoperative diagnosis was a surface lipoma for the lack of clinical experience. Only color Doppler ultrasound is performed in the outpatient clinic. The preoperative examination was not sufficient, so the difficulties of the surgery was increased. We share the process for the clinician.

OBJECTIVE[corrected] To evaluate the method and technique of single-port laparoscopic radical nephrectomy.

METHODSForm 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.

RESULTSThe 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.

CONCLUSIONSingle-port laparoscopic radical nephrectomy is safe and feasible with good cosmetic effect and shows much potential in radical resection of renal carcinoma.
