Abstract
Purpose: So far, it has not been described whether the perioperative course and the pathologic outcome of patients who undergo radical cystectomy (RC) with orthotopic bladder substitution differs if nerve sparing (NS) is performed or not.Material and Methods: In all, there were 472 patients who underwent RC between 2012 and 2019 at our department. We performed a retrospective analysis of 116 patients who underwent RC with ileal neobladder. We analyzed perioperative complications according to the Clavien–Dindo classification system, as well as the pathological outcome.Results: Of 116 patients, 68 (58.6%) underwent RC, and 48 (41.4%) underwent NS RC. Clavien–Dindo complications ≥3b occurred in 15 (12.9%) of all patients. Only infectious complications differed among the groups [NS RC: 25 patients (52.1%) vs. RC: 20 patients (29.4%); p = 0.02]. There was no significant difference concerning tumor stage. Concomitant Cis was present in 24 patients (35.3%) of the RC group and in 27 patients (56.3%) of the NS RC group (p = 0.036). Nodal status and positive surgical margin status of the bladder tumor did not differ among the groups. In all, 42 of all male patients (45.7%) had an incidental prostatic carcinoma. Positive surgical margins concerning the prostate carcinoma occurred in six patients, with all cases in the RC group (p = 0.029).Conclusions: Our data suggest that performing NS during RC in carefully selected patients is a safe procedure and does not impair perioperative outcome. Pathological outcome of NS RC is comparable as well.
Highlights
Radical cystectomy (RC) is still the gold-standard intended curative therapy for muscle-invasive bladder cancer and one therapy option in recurrent high-grade non–muscle-invasive bladder cancer [1]
nerve sparing (NS) RC in male patients was performed with a technique, modified to that initially described by Walsh and Schlegel [11]
Of 116 patients who were eligible for final analysis, 68 (58.6%) underwent RC, and 48 (41.4%) underwent NS RC
Summary
Radical cystectomy (RC) is still the gold-standard intended curative therapy for muscle-invasive bladder cancer and one therapy option in recurrent high-grade non–muscle-invasive bladder cancer [1]. In young and otherwise healthy patients, orthotopic bladder substitution (OBS) is often performed [2]. This continent urinary diversion has several advantages. OBS comes along with a significant prevalence of postoperative erectile dysfunction and urinary incontinence. In 1982, Walsh and Donker [3] were the first to describe that impotence after radical prostatectomy (RP) occurred due to injury of the nerves of the pelvic plexus.
