NARUS 2018: Superior Early Continence After Early Suprapubic Tube Removal in Robot Assisted Radical Prostatectomy – A Prospective Randomized Trial

Las Vegas, NV (UroToday.com) There is still an ongoing discussion on the type and duration of urinary drainage after robot-assisted radical prostatectomy (RALRP) with regards to patient comfort and potential impact on functional results and continence. While several studies demonstrated improved patient comfort after suprapubic tube placement, improved continence and functional results could not be definitely confirmed so far.

Methods

The authors conducted a prospective randomized trial with 3 arms with a 1:1:1 randomization ratio of patients undergoing RALRP. The 3 arms included:
  1. Transurethral catheter removed on day 5 (group 1)
  2. Suprapubic catheter removed on day 5 (group 2)
  3. Suprapubic catheter removed on day 2 (group 3)
During their hospital stay all patients were assessed for incontinence, residual bladder volume and comfort using a questionnaire. After discharge, all patients were followed-up with collection of data on incontinence, voiding and quality of life.

Results

A total of 198 patients were enrolled between June 2016 and July 2017. Only 11 patients had dropped out of the study. No difference between the groups were noted in regards to age, BMI, TRUS prostate volume, preoperative PSA, IPSS and Gleason score.

No differences were noted in the residual bladder volume. Furthermore, no differences could be discerned with regards to complications, however, a significant difference was noted in their insentience, with group 1, group 2, and group 3 patients having 30, 24, and 14 cc on their 12 hour pad test. Four weeks after surgery, continence (less than 1 pad/day) was achieved in 51%, 62% and 76% of patients in groups 1,2, and 3, respectively. 

Conclusions

The authors concluded that there are comparable outcomes for postoperative patient comfort, complication rates and voiding quality in the groups. However, significant differences exist in short term continence rates 4 weeks after catheter removal. RALRP with early removal of a suprapubic catheter may lead to improved early continence.
