Résumé
Background: Mucosal thickness of bladder increases following to the UTI, chemotherapy, neurogenic bladder, posterior urethral valve, stone and inflammation. Due to the importance of normal values of mucosal thickness and existing controversies, this study was performed on normal population visiting medical centers affiliated to Shahid Beheshti Medical University
Materials and methods: This was a cross-sectional study on 212 normal adult individuals. The studied group included all patients underwent ultrasonography. Not due to urinary problems such as abdomen pain, probable anomalies and routine check-up. All those didn't have predisposing factors on increase of mucosal thickness. The probe was 3.5-5 MHZ. The thickness was measured sagitally and cross-sectionally from posterior-lateral trigone. Age, sex and fullness of the bladder were determined as influencing factors on bladder thickness
Results: The range of age was 12 to 70. 78% were female and 22% male. The thickness of full bladder was 2.57+/0.57 mm with the range of 1.41 to 3.65 mm and the thickness of empty bladder was 5.48 +/- 0.12 mm with the range of 7.10 to 3.86 mm
Conclusions: The thickness of bladder was reported to be 2-3 mm in one reference and 4-6 mm in another. The previous findings are compatible to some extent with those from our study for full bladder but nothing mentioned for empty bladder
