RESUMO
This study presented our experience in the treatment of testicular torsion, which may help achieve early diagnosis and improve therapeutic effects. A retrospective analysis was conducted in 71 patients with testicular torsion who were treated in our hospital from October 2007 to April 2011. The age of the patients ranged from 16 days to 34 years. All the patients had unilateral testicular torsion, which took place on the left side in 43 cases and on the right side in 28 cases. The course of the disease varied between three hours to 30 days. Post-operative follow-up was conducted until October 2011. Items examined included signs and symptoms at their first clinical visit, ultrasound findings, treatment in emergency surgery, and post-operative follow-up. In this study, the 71 patients were diagnosed with testicular torsion by color Doppler sonography, 7 had testicular fixation, 63 patients received orchiectomy, while 1 patient did not undergo surgery due to pressure from family members. Post-operative follow-up showed that the one patient's testicle, which had been reserved, atrophied, while all the other survived. No recurrence was found during the follow-up visits. It is concluded that an early diagnosis and surgery is important in improving the survival rate of testicular torsion, and the diagnosis and treatment by the first attending clinician is of critical importance.

RESUMO
This study examined the effect of nicotine on the expression of mutant p53 (mt-p53) in bladder cancer rats. The rat models of bladder cancer were established by infusing N-methyl-nitroso-urea (MNU, 10 mg/kg every 2 weeks for 8 weeks) into the bladder. Pathological examination on the bladder was conducted to confirm the establishment of the model. All the bladder cancer rats were randomly divided into an MNU group and 3 nicotine groups. In the nicotine groups, the rats were intragastrically administered nicotine at different concentrations (25, 15, 5 mg/kg respectively) 3 times per week for 8 weeks. The mt-p53 expression was detected by the immunohistochemical method. The results showed that rat bladder cancer models developed histopathological changes of bladder transitional cell carcinoma. The positive rate of mt-p53 expression in the 3 nicotine groups (25, 15, 5 mg/kg) was 75.00%, 58.33% and 41.67% by the 14th week, respectively, significantly higher than that in the MNU group (33.33%) (all P<0.05). The mt-p53 expression rate was positively correlated with the medication dose and time (P<0.05). It is concluded that nicotine may play an important role in the development of bladder cancer partially by increasing the expression of mt-p53.
RESUMO
The effectiveness and safety of ureteroscopic holmium: YAG laser lithotripsy for managing ureteral calculi was evaluated. Ureteroscopic holmium. YAG laser lithotripsy was performed in 168 ureteral calculi (upper 27 cases, middle 33 cases and lower 108 cases). The results showed that the stone-free rate was 92.6% in the upper ureteral calculi, 93.9% in the middle ureteral calculi and 94.4% in the lower ureteral calculi, respectively. The complication rate was 4.8% (8 cases). It was suggested that ureteroscopic holmium: YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral calculi.

Objective To study the outcome of ureterocele trated by open surgery and by endoscopic manipulation. Methods We reviewed 29 cases of ureteroceles, including 16 intravesical ureteroceles and 13 extravesical ureteroceles. 19 cases were treated by open surgery and 10 by endoscopic procedure. Results 11 cases of intravesical ureteroceles and 8 cases of extravesical ureteroceles under went open surgery, The reoperation rate was 18.1% and 12.5%, respectively. 5 cases of intravesical ureteroceles and 5 cases of extravesical ureteroceles underwent endoscopic treatment,the reoperation rate being 40.0% and 80.0% respectively. Conclusions Endoscopic approach might be the primary management for intravesical ureteroceles, but open surgery is a favorable alternative for extravesical ureteroceles.
