There are two papers in the paediatric urology section this month. The first, from Belgium, assessed the importance of normalising bladder capacity to the age-expected capacity in children with refractory nocturnal enuresis, and evaluated the long-term results when the children reached adolescence. The second paper from the USA assessed the role of apoptosis and proliferation in children with undescended testes.
To assess the importance of normalizing bladder capacity to the age-expected capacity in children with refractory monosymptomatic nocturnal enuresis (MNE), and to evaluate the long-term results when these children grow into adolescence.
PATIENTS AND METHODS
The study included 34 children with refractory MNE; all were treated > 5 years earlier for their MNE using a combined stepwise approach, consisting of retention control training, oxybutynin and an enuresis alarm. Data were obtained on their enuretic state, night-time voiding behaviour and bladder capacity, from a questionnaire and a voiding chart.
Before starting treatment, all patients had a bladder capacity that was too small for their age. After the combined stepwise approach, MNE improved in all patients and 24 (71%) were cured. Although the bladder capacity was increased to the age-expected capacity in 26 (76%), most woke at night to void. Currently, at a mean of 7.7 years after the primary treatment, 28 (82%) of the patients are completely dry at night, of whom 15 (54%) arouse to void for 35% of the nights. Six patients (18%) still have some enuretic episodes. Only those who were dry after primary treatment and remained dry had a normal age-expected increase in bladder capacity. For all others there was a decrease in age-related bladder capacity.
In patients with refractory MNE, a combined stepwise approach improves and may even eliminate enuresis, but normal night-time bladder behaviour in adolescence and adulthood is only achieved in some. Furthermore, about a fifth still have some enuretic episodes.
