Bladder Neck Surgery is not Routinely Needed to Achieve Urinary Continence in Patients with Primary Epispadias.

BACKGROUND

This study aims at investigating the continence outcome in primary epispadias patients treated at a tertiary center. The authors hypothesized that additional continence procedures following primary epispadias repair is not routinely needed.

METHODS

Patients treated for primary epispadias at the authors' institution between 2007 and 2019 and toilet trained, were identified from a prospective maintained database. Males underwent chordee correction, urethroplasty and glanuloplasty. Females underwent genitoplasty with reduction urethroplasty. If continence was not achieved by 4-5 years of age, pelvic floor muscle (PFM) biofeedback therapy was performed. Other continent procedures were discussed with family/patient if still incontinent.

PRIMARY OUTCOME: urinary continence.

SECONDARY OUTCOMES: PFM biofeedback therapy, continence surgery, hydronephrosis. Type of epispadias, age at repair and follow-up presented as median was also reported.

RESULTS

Thirty-three patients (29 males) were included. Twelve had penopubic epispadias, 13 glanular/penile, 4 duplicated urethra, 4 females. Median age at repair: 2 years (IQR 1-3), at follow-up: 8 years (IQR 6-10). Daytime continence: 100 % in penile/glanular; 33 % in penopubic and 75 % in duplicated urethra. Nighttime continence: respectively 92 %, 50 % and 100 %. 24 % of males were intermittently incontinent. All patients except one voided urethrally. One patient underwent bladder neck closure, ileocystoplasty and Mitrofanoff. One girl achieved daytime continence, 2 were intermittently incontinent, one continuously incontinent. All were enuretic. 38 % of boys and 100 % of girls had biofeedback therapy. None had hydronephrosis/renal impairment.

CONCLUSIONS

Most children with primary epispadias can achieve social urinary continence spontaneously or with the support of PFM biofeedback therapy. Other continence procedures should be reserved for patients who do not attain satisfactory continence.

LEVEL OF EVIDENCE: Treatment study - level IV.
