Post void dribble syndrome series#

This immature pattern improves and resolves by the time of toilet training. Neonatal voiding is however characterized by small frequent voids every 1–2 h with an immature pattern of interrupted detrusor-sphincter dyscoordinated voiding seen in 30% of cases with associated incomplete bladder emptying. The initial concept that babies micturate via a reflex spinal pathway is no longer held with evidence that neonates are aware of voiding with involvement of CNS centers and later development of voluntary control.

Post void dribble syndrome series#

Once toilet-training is achieved, voluntary initiation of voiding over a wide range of bladder volumes can be initiated at will in an “on-off” manner facilitated via a series of positive feedback loops using supraspinal pathways.

The bladder is an unusual autonomic visceral organ in that it interfaces with a voluntarily controlled somatic sphincter. Smooth coordination between the two phases of storage and micturition depends on intact neural pathways in the central nervous system in the cortical, pontine, and sacral micturition centers, which allow social planning and timing, coordination, and amplification, respectively. This allows the lowest possible detrusor pressure able to overcome outflow resistance during voiding with complete emptying of the bladder. Voiding or micturition phase where parasympathetic stimulation from the sacral micturition center (S2-S4) via the pelvic nerve facilitates detrusor contraction and internal sphincter relaxation, and somatic input via the pudendal nerve relaxes the external urethral sphincter.
