Long-term functional and oncological outcomes of nerve-sparing and prostate capsule-sparing cystectomy: a single-centre experience

Objectives To evaluate the technical feasibility, oncological and functional outcomes of nerve sparing cystoprostatectomy (NSCP) and prostate capsule-sparing cystectomy (PCSC) for the treatment of organ-confined bladder cancer at a single referral centre. Patients and Methods From April 2001 to June 2012, 60 patients underwent PCSC and 47 were treated with NSCP. Inclusion criteria for PCSC were: fully informed consent for the well-motivated patient; negative transurethral resection of the bladder neck; normal prostatic specific antigen (PSA) level (defined as dL during the first year of the study, which was later lowered to 2.5 ng/dL); and normal transrectal ultrasonography, with biopsy for any suspicious nodule. Patients received a complete oncological and functional follow-up. The Kaplan-Meier method was used to depict survival outcomes after surgery. Results After a median follow-up of 73 and 62 months for PCSC and NSCP, respectively, the 5-year cancer-specific survival was 90% for the PCSC group and 78% for the NSCP group (P = 0.055). Considering complications within 30 days after surgery, 13% and 21% patients had Clavien >= III complications in the PCSC and NSCP groups, respectively (P = 0.2). For functional outcomes, at 3 months after surgery, 54 (90%) and 24 (51%) patients reported full recovery of daytime urinary continence in the PCSC and NSCP groups, respectively (P < 0.001); and for erectile function recovery, 32 (53%) and four (9%) patients in the PCSC group and in the NSCP group were respectively potent without any treatment (P < 0.001). Conclusions NSCP and PCSC are appropriate for a subset of patients with bladder cancer, with excellent oncological and functional results. These surgical procedures should be proposed to well-motivated patients.
