BACKGROUND: The optimal total hip replacement can be prepared by assembling S-ROM prosthesis individually. OBJECTIVE: To evaluate the short-time effect of S-ROM prosthesis total hip replacement for osteoarthritis secondary to developmental dysplasia of hip. METHODS: Totally 57 adult patients (63 hips) with osteoarthritis secondary to developmental dysplasia of hip treated by S-ROM prosthesis for primary total hip arthroplasty from November 2002 to February 2007 were selected. The preoperative and postoperative Harris score were compared. The prosthesis loosening, fracture and subsidence, bone absorption and fracture were followed-up with radiographic results. RESULTS AND CONCLUSION: All patients were followed up from 6 months to 5 years, mean 3.5 years. One patient suffered temporary common peroneal nerve palsy, and recovered after 4 months. One patient suffered hip dislocation, and recovered after manipulative reduction and traction. There were no complications in the rest patients. The Harris hip score was 70.20-92.10, mean 88.30, which was obvious increased than that of before operation (P < 0.05). No loosening, fracture and subsidence of prosthesis, bone absorption or fracture was observed. The results demonstrated that S-ROM prosthesis total hip replacement can receive an excellent short-time effect in treating osteoarthritis secondary to developmental dysplasia of hip.

Objective To evaluate the clinical curative effect and safety of the stapled transanal rectal resection (STARR) in treatment rectocele. Methods Ninety-two cases suffering from rectocele were treated with rectal inferior extremity half circum mucosectomy by PPH stapler. The operative time, operation effect,complication and recurrence rate were studied. Results All cases were operated successfully. The mean operation time was (25 ±8)min,The totol effective rate was 100% ,postoperative complication included inferior abdomen discomfort and pain (32 cases,34. 7%),urinary retention(9 cases,9. 8%) ,anal anus pain(5 cases, 5. 4%) and bleeding(3 cases,3. 3%). The average length of postoperative stay was 1-5 days (average[2. 2 ±0. 9]days). The follow-up period ranged from 4 to 40 months and no recurrence was observed. Conclusion The stapled transanal rectal resection (STARR) has several advantages,such as safety,rapid recovery,good recent therapeutic effect and lower recurrence in treating rectocele.

Objective To compare the curative effect of several surgical treatments for closed urethral injury.Methods A retrospective study was done on 200 cases of closed urethral injury treated with various methods from June 2002 to June 2012,including 44 cases of anterior urethral injury treated with endoscopic transurethral realignment (anterior endoscopic group),32 cases of anterior urethral injury with transperineal urethral repair (repair group),42 cases of posterior urethral injury with transperineal urethral termino-terminal anastomosis (anastomosis group),35 cases of posterior urethral injury with endoscopic transurethral realignment (posterior endoscopic group),and 47 cases of posterior urethral injury with endoscopic transurethral and transvesical realignment (combined endoscopic group).Amount of bleeding,operation time,hospital stay as well as expense,and rate of urethral stricture and erectile dysfunction (ED) in treatment of anterior and posterior urethral injury were compared respectively.Curativeeffect and merits and faults of each treatment were observed.Results Anterior endoscopic group achieved less bleeding [(10 ± 5) ml∶ (100 ± 20) ml,P ＜ 0.05],shorter operation time and hospital stay [(15 ± 6) min∶ (40 ± 15) min,(14.2 ± 1.8) min∶ (28.5 ± 1.5) min respectively,P ＜ 0.05],lower hospital expense and urethral stricture rate[(4 715.42 ± 225.43) RMB∶ (6 886.46 ± 246.78) RMB,39％ ∶ 63％ respectively,P ＜ 0.05] as compared with repair group,but there was no statistical difference in ED rate between the two groups.Whereas in anastomosis group,the most bleeding [(200 ± 30) ml],longest operation time [(60 ± 20) minutes] and hospital stay [(28.7 ± 2.3) days],and highest hospital expense [(6 964.27 ± 275.69) RMB] and urethral stricture rate (95 ％) were detected (P ＜ 0.05).Posterior endoscopic group presented less bleeding [(15 ± 6) ml∶ (50 ± 12) ml,P ＜ 0.05] and shorter operation time [(21.4 ± 1.7) min∶ (21.2 ± 1.5) min,P ＜ 0.05] as compared with combined endoscopic group,but there were no statistical differences in hospital stay as well as expense and urethral stricture rate between the two groups.Moreover,ED rate was not statistically different among anastomosis group,posterior endoscopic group and combined endoscopic group.Conclusions Endoscopic surgery is superior to traditional surgery in terms of blood loss,operation time,hospital stay,and hospital cost.Besides,urethral stricture and ED rates are closely related to the location and severity of injury.

The surgic is the basic method to treat acute peritonitis, and most of the patients are with sep-sis. Recently, with the development of laparoscopic technique, laparoscopic technique has been more and more applied to the treatment sepsis, but the impact on their postoperative inflammatory response and the spread of the bacteria have been the focus of note. Now I make a review, about the research progress of the CO2 pneumoperitonoum in the kind of sepsis in recent years.

Objective To explore the effects of ?-tocopherol on Bcl-2 protein expression of spermatogenic cells in experimental varicocele rats. Methods Thirty adult male Wistar rats were randomly divided into 3 groups(n=10): treatment group (TG) was intramuscularly injected ?- tocopherol (0.5mg/100g body weight, one time daily for 4 weeks) after establishing varicocele model by partial ligation of the left renal vein for 4 weeks, operation control group (OCG)and sham operation group (SOG). After 8 weeks Bcl-2 protein expression in the testes tissues was detected by immunohistochemical method. Results The weight of left testes in TG was obviously heavier than that in OCG(P

Objective To evaluate the significance of t he abnormality of VHL gene and VEGF expression in primary renal cell carcinoma ( RCC). Methods Mutation and abnormal methylation of VHL g ene and the expression of VEGF were dtected by means of multiplex PCR,PCR-SSCP and immunohistochemistry in 42 cases of primary RCC,in 18 specimens adjacent to the neoplastic lesion and in 10 specimens of normal renal tissues. R esults The alteration rate of VHL gene was higher in RCC tissue (61. 9%) than in the normal renal tissue (3.6%,P

Objective To improve the surgical technique for the removal of huge staghorn stones. Methods 202 cases treated with an incision of the intrarenal sinus supplemented by a postrenal lower pole segmental incision for the removal of huge kidney stones were studied. Results The biggest stone was 9.8 cm?5.0 cm?3.2 cm and in one case the stones amouned to 74. The average postoperative hospitalization days was 12.8. Postoperative examination with KUB+IVU or B ultrasound revealed residual stone in 9 cases, the diameters being less than 0.8 cm. Conclusions The procedure needs no interruption of renal pedical and with the advantages of simple,less bleeding,complete removal of calculus,and preservation of renal function.

Objective To study the safety and efficiency of transurethral electrochemical therapy (ECT) on benign prostatic hyperplasia (BPH). Methods An experimental electrechomical therapy on prostate has been carred out in 12 dogs.The prostate tissue and the nearly organs were studied for any morphological changes.On the basis of the experiment,ECT was then carried out for 11 patients suffered from BPH.The relevant parameters were assessed. Results In the experimental group,good therapeutic effect was achieved if the electrode was 10 mm shorter than the prostatic urethra.On the other hand if the electrode was 10 mm longer than the prostatic urethera,urethro-rectal fistula and urine incontinence might result.In the clinical group,the effective rate was 82% with no complication observed.Before the treatment RI was 0.70?0.04 and 2 weeks after treatment 0.73?0.03;IPSS 26.7?6.2 and 19.5?4.7;QOL 4.9?0.5 and 3.5?0.6;Qmax (7.8?2.0) and (12.4?3.1)ml/s;PVR (129.1?40.8) and (64.1?27.4)ml;V (48.0?13.1) and ( 47.0?13.5)ml.There was significant difference of IPSS,QOL,Qmax,PVR,RI before and after treatment (P0.05). Conclusions With proper maniputation and adequate length of the electrode used,ECT is a safe,efficient and mini-invasive means for treating BPH in high risk patients nontolerable to open surgery.

Objective To evaluate the effect of incision of the intrarenal sinus plus postrenal low pole segmental incision for removal of calculus on the renal hemodynamics. Methods The hemodynamic changes of intrarenal and incisional sites in 98 cases with complex calculi were consecutively monitored by color Doppler ultrasonograph before operation and also 1 month,3 months,6 months after operation.The ratio(S/D) of the peak flow-rate in systole(S),the flow-rate at the end of diastole(D),and the resistant index(RI) of the intrarenal chief renal arteries and intersegmental arteries and interlobar arteries were analyzed.The signals of blood stream in segmental incision were divided into four classes(Ⅰ to Ⅳ) and were observed. Results The changes of the intrarenal hemodynamics were related to the degrees of hydronephrosis(P0.05),but it caused the blood stream to be obstructed in the area of incision where the signals of blood stream showed classes Ⅲ to Ⅳ.The patients generally recovered after 3 to 6 months,and the time of recovery was associated with the degrees of hydronephrosis Conclusions It is concluded that the incision of the intrarenal sinus plus postrenal low pole segmental incision for removal of calculus is an effective and safe method for treat-ment of complex renal calculus.
