RESUMEN
Radical cystectomy (RC) is the gold standard treatment for patients with organ-confined bladder cancer. However, despite the success of this treatment, many men who undergo orthotopic neobladder substitution develop significant erectile dysfunction and urinary symptoms, including daytime and nighttime urinary incontinence. Prostate-capsule-sparing radical cystectomy (PCS-RC) with orthotopic neobladder (ONB) has been described in the literature as a surgical technique to improve functional outcomes in appropriately selected patients. We performed a systematic review and meta-analysis of manuscripts on PCS-RC with ONB published after 2000. We included retrospective and prospective studies with more than 25 patients and compared PCS-RC with nerve-sparing or conventional RC. Studies in which the entire prostate was spared (including the transitional zone) were excluded. Comparative studies were analyzed to assess rates of daytime continence, nighttime continence, and satisfactory erectile function in patients undergoing PCS-RC compared with those undergoing conventional RC. Fourteen reports were included in the final review. Our data identify high rates of daytime (83%-97%) and nighttime continence (60%-80%) in patients undergoing PCS-RC with ONB. In comparative studies, meta-analysis results demonstrate no difference in daytime continence (RR:1.12; 95% CI: 0.72-1.73) in those undergoing PCS-RC compared to those undergoing conventional RC. Similarly, nighttime continence was similar between the 2 groups (RR:1.85; 95% CI: 0.57-6.00. Erectile function was improved in those undergoing PCS-RC (RR 5.35; 95% CI: 1.82-15.74) in the PCS-RC series. Bladder cancer margin positivity and recurrence rates were similar to those reported in the literature with conventional RC with an average weighted follow-up of 52.2 months. While several studies utilized different prostate cancer (CaP) screening techniques, the rates of CaP were low (incidence 0.02; 95% CI:0.01-0.04), and oncologic outcomes were similar to standard RC. PCS-RC is associated with improved nighttime continence and erectile function compared to conventional RC techniques. Further work is needed to standardize CaP screening before surgery, but the data suggest low rates of CaP with similar oncologic outcomes when compared to RC.

OBJECTIVES: To summarize the published literature regarding pelvic organ prolapse, dehiscence or evisceration, vaginal fistula, and dyspareunia after radical cystectomy and to describe the management approaches used to treat these conditions. METHODS: Ovid MEDLINE, Ovid EMBASE, and Web of Science were systematically searched from January 1, 2001 to January 25, 2021 using a combination of search terms for bladder cancer and radical cystectomy with terms for four categories of vaginal complications (prolapse, fistula, evisceration/dehiscence, and dyspareunia). A total of 229 publications were identified, the final review included 28 publications. RESULTS: Neobladder vaginal fistula was evaluated in 17 publications, with an incidence rate of 3 - 6% at higher volume centers, often along the anterior vaginal wall at the location of the neobladder-urethral anastomosis. Sexual function was evaluated in 10 studies, 7 of which utilized validated instruments. Maintaining the anterior vaginal wall and the distal urethra appeared to be associated with improved sexual function. Pelvic organ prolapse was assessed in 5 studies, only 1 used a validated questionnaire and none included a validated objective measure of pelvic organ support. CONCLUSION: There is a need for more prospective studies, using standardized instruments and subjective outcome measures to better define the incidence of vaginal complications after radical cystectomy for bladder cancer, and to understand their impact on quality of life measures.
