Bladder bowel dysfunction scoring system (BBDSS): A novel, illustrated questionnaire for evaluation of voiding dysfunction in children.

Introduction: We sought to evaluate the reliability and validity of a new, illustrated questionnaire, the bladder bowel dysfunction symptom score (BBDSS) in the assessment of overactive bladder (OAB) and bladder bowel dysfunction (BBD).

Methods: The BBDSS questionnaire consisted of 12 structured questions. This pilot study was designed with two principal groups of questions: one group to assess bladder symptoms and the other to assess bowel dysfunction during the preceding month.

Voiding efficiency in children is significantly impaired by the presence of the urethral catheter during pressure-flow studies.

Background: Little is known about the effect of catheterization during pressure-flow studies (PFS) on voiding efficiency in children. Our objective was to determine the effect of urethral catheterization on Qmax and flow index (FI) during PFS compared to the free flow of uroflowmetry (UF).

Methods: We retrospectively reviewed 63 consecutive children who underwent UF and PFS at our center on the same day (2019-2022).

How can we measure the renal pelvic anteroposterior diameter in postnatal isolated hydronephrosis?

Introduction: The anteroposterior diameter (APD) of the renal pelvis is a commonly used ultrasound parameter in the evaluation and management of hydronephrosis. It has been established that an APD value associated with pyeloplasty is around 25 mm. Some believe the APD should be measured at the innermost part of the renal pelvis while others suggest that it should be done at the renal contour.
