There was no significant difference between total and partial urogenital mobilization procedures regarding postoperative urinary continence in our cohort and the literature. The urinary continence rate was 96% in the congenital adrenal hyperplasia/urogenital sinus group and 89.5% in the cloacal group.
The treatments explored in this experiment provided novel examples of cost-effective porcine models for the study of nephrolithiasis. EG + VD had the strongest indicators of nephrolithiasis without nephrotoxicity.
Objectives: To evaluate the sensitivity, specificity, and false-positive rate of the nuclear matrix protein-22 (NMP22) test in patients with end-stage renal disease (ESRD) and microscopic hematuria in order to avoid unnecessary follow-up tests for patients with false-positive NMP22 test results. Patients and Methods: Patients with ESRD were screened for microscopic hematuria as part of the pre-transplant workup. Patients with documented microscopic hematuria underwent workup as recommended by the American Urological Association. Results: Between January 2006 and April 2012, 277 patients with ESRD were referred to the Department of Urology for pre-transplant evaluation. Fifty-seven (22.6%) patients were found to have microscopic hematuria and underwent further testing. Nineteen (33.3%) patients demonstrated a positive NMP22 test result and 38 (66.7%) had a negative NMP22 test result. The false-positive rate was 32.7%. The sensitivity and specificity of the NMP22 test in this patient population were 50% and 67%, respectively. The positive predictive value of the test was 52.6% and the negative predictive value 97.3%. Especially noteworthy, the two detected transitional cell cancers of the urinary bladder were both demonstrated during cystoscopy, independent of their NMP22 or urine cytology test result. Conclusions: Our study revealed a significantly increased NMP22 test false-positive rate, low sensitivity, and specificity in the setting of high prevalence of microscopic hematuria, proteinuria, and low glomerular filtration rate in patients with ESRD. Therefore, cystoscopy remains the gold standard for patients with ESRD and microscopic hematuria for pre-transplant evaluation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
