Vesicoureteral reflux is a major problem in childhood affecting 1% of all children. There are various surgical methods for vesicoureteral reflux treatment. Current study evaluates effectiveness and success rate of the Lich-gregoir procedure in treatment of the vesicoureteral reflux. In a descriptive-analytical study, 32 children with 47 reflux unit underwent Lich-gregoir anti-reflux procedure in Imam Reza and Amir-al-Momenin Hospitals, Tabriz between March 2008 and August 2011. Surgery outcome and success rate, sonographic findings and complications rate were recorded in follow-up. Patients mean age was 5.85 +/- 3.81 years. 28.1% were male and 71.9% were female. Reflux was unilateral in 53.1% and bilateral in 46.9%. Vesicoureteral reflux grade I to V was in one, 1, 13, 22 and ten patients, respectively. Voiding Cystourethrogram (VCUG) findings were abnormal in all cases before operation. Surgery success rate in first 6 months was 95.7% and was 100% in 8 months after operation. Hydronephrosis disappeared after operation in all cases. Complication occurred in 2 cases (6.25%) with bilateral reflux including urinary intention and lymphocele. Lich-gregoir anti-reflux procedure technique is accompanied with higher success rate, low complication and hydronephrosis improvement and is an appropriate treatment for vesicoureteral reflux in children.

To validate the Persian version of the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) as a standard questionnaire for assessment of urinary incontinence (UI). After translation and back translation of the questionnaire, the harmonized translation was pre-tested in a pilot study on 28 patients. The final Persian version of the ICIQ-UI SF was administered to 123 consecutive patients aged ≥ 16 years complaining of UI. The psychometric aspects of the questionnaire, such as reliability and construct validity, were assessed and compared with full urodynamics study's findings as the gold standard diagnostic test. Mean age of the participants was 46.30 ± 13.14 years (range, 16 to 72 years). Based on ICIQ-UI SF, the prevalence of mixed urinary incontinence, stress urinary incontinence and urgency urinary incontinence was 35%, 34.1%, and 30.9%, respectively. Cronbach's alpha coefficient was calculated 0.75, which indicates the high reliability of this questionnaire in determination of UI. The obtained Weighted Kappa Index in determining the value of the test-retest was 0.70, and Pearson Correlation Coefficient was calculated 0.93 and intra-class correlation coefficient was 0.84. Persian version of ICIQ-UI SF is a simple, valid, and reliable method for evaluation of patients with UI. Significant correlation exists between ICIQ-UI SF score and urodynamics parameters.
