The emerging experience in urethra-sparing cystectomy in women undergoing subsequent orthotopic lower-urinary-tract reconstruction with regard to the anatomy of the remnant urethra, patient selection, refinements of the surgical technique, the patients' outcome with respect to the underlying disease, the risk for tumor recurrence, and postoperative urodynamics are the main focus of this report. In the present study, 30 carefully selected female patients underwent orthotopic reconstruction of the lower urinary tract. Surgical variations emerging from the first learning curve, including nerve-sparing anterior exenteration, vaginal reconstruction, omental support of the neobladder floor, and ureterointestinal anastomosis, were applied in 21 patients with lower-urinary-tract reconstruction. Of 24 patients followed for more than 6 months, 21 (87.5%) are continent at daytime, 19 (79%) have nocturnal continence, and only 1 (4%) requires self-catheterization; 3 patients with urinary retention were successfully treated for obstructed ileal valves. After a follow-up period of 2–41 (mean 15.4) months one patient each developed local recurrence (uterine adenosarcoma) after 13 months and distant metastasis transitional-cell cancer of the bladder after 3 months; all other patients are currently free of disease. Urethra-sparing surgery has established itself in selected women with bladder cancer. Refinements in the technique of radical cystectomy and orthotopic creation of a neobladder to the urethra may improve the continence, spontaneous micturition, and surgical oncological outcome of these patients.
