The Pippi Salle urethral lengthening procedure; experience and outcome from three United Kingdom centres.

Abstract

To assess the outcome of the Pippi Salle (Kropp onlay) urethral lengthening procedure in the treatment of neuropathic urinary incontinence. Twenty-eight patients (12 males and 16 females, mean age at surgery 12.6 years, range 7-32) were identified who underwent the procedure between 1993 and 1997 in the United Kingdom. Outcomes were assessed by a review of the case notes. Of the 28 patients, 18 (64%) were rendered continent by day, and 17 (61%) by day and night. Twelve of the 16 females were completely dry, and a further girl was dry by day, giving overall daytime continence in 13 patients; five males were rendered continent (P=0.03, chi-square test). Four patients required revision surgery; in five patients (two females and three males) the method was abandoned and they underwent an alternative procedure, and a further four are being reassessed. The Pippi Salle procedure should be considered as a first-line treatment option for neuropathic incontinence in females. Its place in the management of incontinent males is less convincing.
