- Abstract:
- Objective To explore variation tendency of urinary flow after tubularized incised plate (TIP) urethroplasty in children with hypospadias.Methods Retrospective review was conducted for 92 boys with hypospadias undergoing TIP urethroplasty from January 2019 to December 2019.Uroflowmetry was performed at Month 1/3/6/12 preoperatively to examine the variation of urinary flow.Also the data of urinary flow were collected from 180 normal boys as a control group.Obstructive urinary flow was present if maximal urinary flow (Qmax) dropped by 2 standard deviation lower than normal.Results Preoperative Qmax was (10.4±4.3) mL/s and postoperative Qmax (5.6±6.4),(4.9±9.2),(7.0±0.5) and (8.1±1.4) ml/s at Month 1/3/6/12.Obstructive flow was relieved in late stage after TIP urethroplasty.However,preoperative and postoperative urinary flows were lower in hypospadiacs than that in normal boys.Conclusion Urinary flow declines after TIP urethroplasty in hypospadiacs.It drops to the lowest level at Month 3 post-operation and then rises.Unless symptomatic,a conservative approach is preferable.
