Challenges in e-Health: The effect of digitalisation of frequency voiding charts on compliance in paediatric patients. Randomised controlled trial comparing digital and versus paper frequency voiding charts.

Objective: Frequency voiding charts are commonly used to gain better insight into the voiding and drinking behaviours of patients with voiding symptoms. Non-compliance when filling out a chart is known to be high. The use of a digital application might increase adherence, but little research has been conducted on this topic.

Development of a prediction model for postoperative complications after primary hypospadias correction.

Purpose: To develop a prediction model for postoperative complications after primary one-stage hypospadias correction to improve preoperative parental counseling.

Materials And Methods: In this retrospective cohort study, data were collected from 356 patients with anterior or middle hypospadias who had a one-stage hypospadias correction from 2003 onwards. Potential treatment- and patient-related factors were selected and used to develop a prediction model for postoperative complications within one year (wound-related complications, urinary tract infections, fistulas, stenosis, and prepuce-related complications).

Level of agreement on postoperative complications after one-stage hypospadias correction comparing medical records and parent reports.

Purpose: To analyze agreement on postoperative complications after hypospadias surgery according to medical records and parents' reports.

Materials & Methods: In this retrospective cohort study, data were collected from 409 children who received an initial one-stage hypospadias correction in the Radboudumc, The Netherlands. Postoperative complications according to medical records were compared with parent-reported complications in an online questionnaire.
