Objective To investigate the efficacy of minimally invasive percutaneous nephrolithotomy(MPCNL) for impacted upper ureteric calculi.Methods Retro-urethral catheterization was conducted in the diseased ureter under cyctoscope.After a channel from the skin surface into the middle calyx was established under the guidance of X-ray or B ultrasonography,pneumatic lithotripsy was conducted to break up stones under ureteroscopy.Results The success rate of pneumatic lithotripsy was 100%.The rate of postoperative macroscopic hematuria was 55.1%(27/49).The symptom lasted one to three days in 26 cases,and 1 case had apparent hematuria with blood clot flowing out from nephrostomy tube,which lasted 8 days.10.2%(5/49) of cases was complicated with postoperative pyrexia.The stone-free rate in one week and one month postoperatively was 93.9%(46/49) 98.0%(48/49),respectively.Follow-up observations in 49 cases for 1-12 months(mean,5 months) showed no major complications.Conclusions MPCNL for impacted upper ureteral calculi has the advantages of simple performance,less complications and satisfactory efficacy.

Objective To compare the safety and clinical effect of laparoscopic partial nephrectomy ( LPN) on small renal cell carcino-ma. Methods The records of 65 patients who underwent partial nephrectomy in our hospital from March 2008 to March 2013 were retrospec-tively analyzed. 35 patients were given open partial nephrectomy and the other 30 patients were given LPN. Compared the operative time,blood loss,warm ischemia time,length of stay,positive marginrate,and occurance rate of complications between the two groups. Results There was no statistical difference in the mean size of tumor in the two groups. Compared to the OPN group,there was less blood loss,operative time, hospital stays and warm ischemia time in the LPN group. There was neither positive surgical margin nor renal function damage in the two groups. And during the follow-up period ranged from 6 to 18 months,there was no local recurrence. Conclusion Laparoscopic partial ne-phrectomy has a shorter operation time,less blood loss,shorter length of hospital stay compared with open partial nephrectomy,and it wouldn 't extend the time of warm ischemia,while the clinical effect of the two methods are similar.

OBJECTIVE: To summarize advances in clinical application of ureter stent and its biocompatibility. METHODS: A computer-based online search of CNKI (1989/2009) and Medline (1989/2009) was performed with the key words of "ureter, biocompatibility, stent, treatment, complications" in Chinese and English respectively. A total of 51 articles were collected. and 21 were included. The treatment advances and its biocompatibility of ureter stent were summarized, and clinical application advances, biocompatibility and complication prevention of ureter stent were explored. RESULTS: Ureter stent includes polymerizer, metal and degradable material stents. As the common implants in treatment of upper urinary tract diseases, ureter stent functions as stent and internal drainage, and relieve ureteral obstruction, prevent leakage of urine postoperatively and ureterostenosis. Complications following ureter stent implantation include stent shifting, urine reflux, irdtative symptoms of bladder, fouling and stone formation as well as infection. However, these complications can be relieved through positive treatment. CONCLUSION: Ureter stent is an effective approach to treat urologic disease, but the biocompatibility required improvement. Rigorous operation during stent implantation and positive treatment of complication can effectively prevent complications.

Objective:To investigate the effect of free wrist crease flap based on the superficial palmar branch of radial artery in the treatment of compound tissue defect of dorsal finger.Methods:From January 2015 to June 2019, the clinical data of patients admitted to the Department of Hand Surgery, Xuzhou Renci Hospital with skin, soft tissue and tendon defects of dorsal fingers, with or without bone exposure, were retrospectively analyzed. The free wrist crease flap based on the superficial palmar branch of radial artery was used. For patients with dorsal finger wounds less than 2.5 cm in length, palmaris longus tendon was used in the flap to repair, and the direction of flap incision and dorsal finger repair was consistent. If the length of dorsal finger defect was more than 2.5 cm, the palmaris longus tendon was not carried in the flap. The wrist crease flap based on the superficial palmar branch of the radial artery was harvested, and the free palmaris longus tendon was used to repair the defect along the same incision. The flap was selected according to the left and right wrist donor site flap and rotated 90° counterclockwise or clockwise to cover the dorsal finger wound. The flap survival and texture were followed up after operation. The total active movement(TAM) of fingers was evaluated according to the trial standard for the evaluation of the upper limb function of the Hand Surgery Society of the Chinese Medical Association.Results:A total of 17 patients were enrolled in this study, including 12 males and 5 females. The mean age was 39.5 years (range, 21-65 years). There were 10 cases of left finger and 7 cases of right finger. The area of dorsal finger skin defects ranged from 1.5 cm×1.3 cm to 3.8 cm×2.0 cm, and the area of flap ranged from 1.8 cm×1.5 cm to 4.0 cm×2.2 cm. The patients were followed up for 3 to 48 months, with an average of 16.5 months. All the flaps survived and healed well. The texture of the flap was good, and no obvious swelling was observed. Venous crisis occurred in 1 case 18 hours after operation. The stitches were removed, the edge of the flap was bled, and the flap survived after 10 days. All wrist donor sites were sutured directly and healed well after operation. There was no abnormality in wrist flexion and extension function. The TAM of fingers was rated as excellent in 12 cases, good in 4 cases, and fair in 1 case.Conclusions:The free wrist crease flap based on the superficial palmar branch of radial artery is an alternative method for repairing compound tissue defect of dorsal finger. The recipient flap has no bloated appearance. Finger extension function could be reconstructed. The wound at the donor site is small and could be closed directly.
