Functional Assessment of the Hautmann Ileal Neobladder with Chimney Modification Using Uroflowmetry and a Questionnaire

Abstract EN

Urinary diversion reconstruction is essential after radical cystectomy and neobladder reconstruction is accepted as a fine option.

This study included 51 patients, who underwent radical cystectomy with orthotopic neobladder reconstruction by a Hautmann ileal neobladder with chimney modification from 2006 to 2014.

Functional outcomes were evaluated using a questionnaire and uroflowmetry.

Perioperative complications were analyzed retrospectively.

The mean follow-up period was 36.1 months.

Eighty-six percent of patients voided without clean intermittent catheterization (CIC) assistance.

CIC was used 1-2x per day or every time they voided in 8% and 6% of patients, respectively, and 71% of patients were continent.

The percentages of patients who used 1, 2, 3-4, and ≥5 pads per day were 15%, 6%, 2%, and 6%, respectively.

Daytime and nighttime continence were achieved in 86% and 69% of patients, respectively.

Daily mucus leakage was reported in 69% of patients.

The mean maximum neobladder capacity, voided volume, postvoid residual volume, and maximum flow rate were 413.2 mL, 370.6 mL, 43.7 mL, and 20.8 mL/s, respectively.

Eighteen early and 5 late complications developed in 13 and 5 patients, respectively.

Reoperations were needed in 7 patients.

The Hautmann ileal neobladder with chimney modification provided satisfactory results regarding functional outcomes.
