Surgical and Functional Outcomes of Bladder Neck Incision for Primary Vesico-Urethral Anastomosis Stricture after Robot-assisted Radical Prostatectomy are Influenced by the Presence of Pre- or Postoperative Radiotherapy.

Abstract

RESULTS

BNI was performed in 90 patients. The median time between first BNI and last follow-up was 32 months (interquartile range 10-58, range 0-171). The majority of VUAS occurred within 6 months after (S)RARP. In those who underwent BNI, recurrent VUAS was reported in 12%, 57%, 29%, and 50% of patients after RARP-only, VUAS pre-SRT, VUAS post-SRT, and SRARP, respectively. Ultimately, transurethral micturition was possible in 94%, 93%, 71%, and 80%, respectively. Severe urinary-incontinence rates (>1 pads/d) were 6%, 16%, 10%, and 29% for RARP-only, VUAS pre-SRT, VUAS post-SRT, and SRARP patients, respectively.

METHODS

A retrospective cohort study was performed with patients who underwent BNI for VUAS after RARP in a high-volume prostatectomy centre between 2006 and July 2021. Data was collected from patient charts. The cohort was divided into 4 groups: VUAS after (1) RARP-only, (2) RARP, but before salvage radiotherapy (SRT) (VUAS pre-SRT), (3) RARP and after SRT (VUAS post-SRT), and (4) primary radiotherapy and salvage RARP (SRARP). The VUAS recurrence rates, the ability to perform functional transurethral micturition and the post-BNI urinary continence rates were reported.

OBJECTIVE

To report the intermediate- to long-term outcomes of bladder neck incision (BNI) for vesico-urethral anastomosis stricture (VUAS) after robot-assisted radical prostatectomy (RARP) and the influence of pre- or post-RARP radiotherapy on these outcomes.

CONCLUSION

Primary radiotherapy before RARP and SRT after RARP significantly influenced the success rates of BNI. Those who underwent BNI after SRARP had worse outcomes than patients who underwent RARP only.
