Objective To summarize the experience in diagnosis and treatment of ectopic ureter in children. Methods A total of 22 cases (21 females and 1 male;mean age of 4 years,range from 1 month to 12 years) of ectopic ureter were analyzed retrospectively.Of them,17 cases had unilateral ectopic ureters and 5,bilateral.Normal,divided urination accompanied by abnormal leakage of urine occurred in 18 cases;completely continous leakage of urine in 3;and obstruction of upper urinary tract with infection of urinary system in 1.Fourteen cases had opening of ectopic ureters in vaginas,4 in urethras,3 in vestibula and 1 in bladder necks. Results Of the 22 cases 20 underwent surgical procedures.Of the 20 cases,11 had total nephrectomy and 7,partial nephrectomy.After the operation,leakage of urine disappeared,but 3 cases had syndrome of ureteral stump remnant.One case who underwent bilateral ureter-bladder reimplantation had mild urinary incontinence after the operation.One case who had vesica replaced with rectum was followed up for 5 years,the post-operative result was excellent. Conclusions It is of critical importance to establish definite diagnosis and to select appropriate mode of operation for the successful treatment of ectopic ureter in children.

Ⅳ?were cured by anti-reflux ureteral reimplantation after 1 year;in the other 9 cases, VUR disappeared within 4 years. In the 18 cases ac ;ompanied with hydronephrosis/partial hydronephrosis, hydrops disappeared in 3 years in 15 cases,and it cisappeared after 10 years in 3 cases. All the ureteroceles in 88 children disappeared 1 year after the procedue. Conclusions Transurethral electroscission fenestration of ureterocele through cystoscope is a simple,effective and minimal invasive procedure for children with ureterocele.

Objective To investigate the correlation between ipsilateral posterior cerebral artery laterality (PCAL) and the outcomes in patients with ischemic stroke in the middle cerebral artery (MCA) territory. Methods From June 2015 to December 2016, patients with acute ischemic stroke in the MCA territory admitted to the Second People's Hospital of Hefei were enrolled. Magnetic resonance angiography (MRA) was used to assess PCAL. The outcome was evaluated by the modified Rankin scale at 3 months after onset. 0-2 was defined as good outcome and > 2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcome. Results A total of 111 patients with ischemic stroke in MCA territory were enrolled, including 47 (42. 3％) PCAL and 30 (27. 0％) poor outcomes. The baseline NIHSS score in the PCAL group was significantly lower than that in the non-PCAL group (5. 13 ± 3. 29 years vs. 7. 03 ± 5. 676 years, t = 2. 058; P = 0. 042). There were significantly differences in the proportion of diabetes mellitus (29. 6％ vs. 10. 0％; χ2 = 4. 583, P = 0. 032), PCAL (51. 9％ vs. 16. 7％;χ2 = 11. 101, P = 0. 001) and smoking (25. 9％ vs. 13. 3％; χ2 = 4. 943, P = 0. 026), as well as age (63. 9 ± 11. 8 years vs. 71. 0 ± 6. 7 years; t = 2. 688, P = 0. 007), baseline diastolic blood pressure (89 ± 13 mmHg vs. 82 ± 10 mmHg; t = -2. 249, P = 0. 025; 1 mmHg = 0. 133 kPa) and baseline NIHSS score (5. 02 ± 3. 67 vs. 9. 47 ± 6. 20; t = 3. 883, P < 0. 001) between the good outcome group and the poor outcome group. Multivariate logistic regression analysis showed that PCAL was associated independently with good outcome (odds ratio [OR] 0. 272, 95％ confidence interval [CI] 0. 083-0. 888; P = 0. 031), while advanced age (OR 1. 088, 95％ CI 1. 022-1. 157; P = 0. 008) and high baseline NIHSS score (OR 1. 224, 95％ CI 1. 077-1. 391; P = 0. 002) were associated independently with poor outcome. Conclusion PCAL is associated independently with good outcome in patients with ischemic stroke in MCA territory.
