Objective To explore the indication,technique and complications of Snodgrass operation in hypospadias repairment.Methods From Sep.2005 to Nov.2006,22 boys from 2 to 18 years old with hypospadias were treated with Snodgrass modification.The procedure was performed in 16 patients as a primary repairment and in 6 patients as the 2-stage repairment.The entire length of the urethral plate was incised along the midline in primary repairment,and the skin flaps and residual urethral plate were incised in the 2-stage repairment.The length of neourethra was from 1 to 10 cm.The neourethra was tubularized over a F 6 or F 8 catheter.The urethral stent was removed in 10 to 14 days pos-toperatively.Results Of the 22 patients,18(81.8%) required no other surgery as the repairment provided a normal appearing penis(straight,terminal meatus, cosmetics) without complications.Fistul aoccurred in 4 patients(18.2%) and meatal stenosis in 1 patient.Conclusion Snodgrass operation creates a vertical slit-like neomeatus.The procedures restores good function and normal appearance to the penis.

Objective To compare the curative effects of CT-guided ethanol injection and lauromacrogol injection into the sac cavity in treating ovarian endometriosis cysts. Methods A total of 86 patients with ovarian endometriosis cyst were enrolled in this study. The patients were divided into ethanol group (n=44) and lauromacrogol group (n=42). Under CT guidance, injections of ethanol or lauromacrogol into the sac cavity of ovarian endometriosis cysts were respectively performed for the patients of both groups. The patients were followed up for six months, and the curative effects and the complications were analyzed. Results Six months after the treatment, the cure rates of ethanol group and lauromacrogol group were 95.50%and 92.86%respectively, and no statistically significant difference in cure rate existed between the two groups (P>0.05). The preoperative serum CA125 levels of the ethanol group and lauromacrogol group were (48.42±23.68)μg/L and(49.21±22.83) μg/L respectively, and the post operative ones were (23.56±5.89) μg/L and (25.49± 6.10) μg/L respectively; the differences between the preoperative data and the postoperative data were statistically significant in both groups (P<0.05), although the differences in serum CA125 levels between the two groups were not significant (P>0.05). The incidence of postoperative complications in the lauromacrogol group was obviously lower than that in the ethanol group (P<0.05). The cure time in the ethanol group was shorter than that in the lauromacrogol group, although the difference was not significant after six months. Conclusion For the treatment of ovarian endometriosis cysts, CT-guided lauromacrogol injection into the sac cavity has reliable curative effect. Compared to ethanol injection, injection of lauromacrogol is safer and has fewer adverse reactions. Therefore, this technique should be recommended in clinical practice. Serum CA125 can be used as an indicator for the evaluation of curative effect.

25 mmHg) had no response to conservative management, and,therefore,had to be decompressed by invasive procedure,including 6 patients performed by decompression laparotomy,2 patients by laparoscopic decompression and 5 patients by ultrasound/computed tomography location and needle paracentesis drainage.These 13 ACS patients had obvious amelioration in physiological variables (hemodynamic,respiratory and tissue perfusion) after 24 hour post-decompression (P

OBJECTIVE:To provide reference for promoting the prior usage of essential medicines and scientifically selecting of antitumor medicines in the national and local drug reimbursement list. METHODS:Entering the Human Resources and Social Se-curity Bureau websites in 10 cities(Beijing,Shanghai,Guangzhou,Nanjing,Wuhan,Xi’an,Chengdu,Shenyang,Jinan and Gui-yang),drug reimbursement list was downloaded to statistically analyze the containing of antitumor medicines(including 24 essential medicines). RESULTS:In antitumor medicines,there were 5 cities with more than 100 varieties,of which Shanghai had 255 vari-eties,which was far more than other cities;the numbers of medicines in class A were near 30 in all the cities except Beijing(67 va-rieties),and the number of class B was highest in Shanghai and lowest in Beijing. All the drug reimbursement lists in 10 cities con-tained 24 antitumor essential medicines,however,the classification was different according to the dosage forms,among which, parts of formulations of cytarabine(injections),doxorubicin(injections),busulfan (often release oral dosage forms),fluorouracil (often release oral dosage forms,injections),cyclophosphamide(often release oral dosage forms,injections),methotrexate(often release oral dosage forms,injections)and cisplatin were classified as class A medicines in all cities;oxaliplatin(injections)and pa-clitaxel (injections) were classified as class B medicines;busulfan,fluorouracil,cyclophosphamide and methotrexate were classi-fied as class B in Shanghai only. CONCLUSIONS:There are some differences in the distribution of antitumor essential medicines in drug reimbursement list in each city,the varieties in developed cities are relatively more,and developing cities are less. It is sug-gested to consider the tumor epidemiology characteristics and economic situations,reasonably select antitumor essential medicines into drug reimbursement list and reasonably adjust the proportion of class A and B to ensure the basic medication and drugs’reim-bursement.
