Treatment of primary nocturnal enuresis persisting into adulthood.
OBJECTIVE
We evaluate the therapeutic effectiveness of treating monosymptomatic primary nocturnal enuresis (PNE) that has persisted into adulthood.


METHODS
Patients older than 18 years with persistent monosymptomatic primary nocturnal enuresis were treated with 20 to 40 microg. desmopressin (DDAVP) nightly for 6 months. If the patients remained incontinent on maximal pharmacotherapy or if they became incontinent after cessation of DDAVP we initiated treatment with an enuretic alarm for 6 months. Patients not responsive to DDAVP or the enuresis alarm were given a trial of 50 mg. imipramine nightly. All patients were reassessed for continence 18 months after initiation of the treatment protocol.


RESULTS
We treated 29 patients of a median age of 20 years (range 18 to 33) who were enuretic more than 4 nights per week. With the initial DDAVP treatment 19 (66%) became continent (enuresis 0 or 1 night a month) but after discontinuation of DDAVP only 2 (7%) remained continent. Of the 27 patients subsequently treated with an enuretic alarm 9 (33%) became continent and 18 had persistent enuresis. Of these 18 patients 11 resumed DDAVP and became dry, while 7 nonresponsive to DDAVP were given imipramine and 2 (29%) are continent.


CONCLUSIONS
Overall, 83% of patients (24 of 29) achieved continence, including 38% (11 of 29) who are continent off all treatment modalities and 45% (13 of 29) who are currently continent on pharmacotherapy (11 on DDAVP and 2 on imipramine). The remaining 17% of patients (5 of 29) have persistent primary nocturnal enuresis recalcitrant to all therapeutic attempts.
