Functional Outcomes After Prostatic Cryosurgery

Objective: To assess the functional effects of prostatic cryosurgery on micturition.Material and methods: Prospective study of men who underwent cryosurgery (CS) for prostate cancer between 2013 - 2015. Low urinary tract symptoms (LUTS) and quality of life (QoL) were assessed 1 month before surgery using IPSS questionnaire, a three-day voiding diary (3 DVD) and uroflowmetry with ultrasound-measured postvoid residual volume. Need of medical treatment for LUIS was also recorded. The same assessment was performed at 3, 6 and 12 months after CS. Outcomes after surgery were compared to those prior to surgery.Results: Forty-five patients underwent a CS during the study period, of whom 25 patients could be recruited in the study. Mean age was 73.5 years (range 66-84). Nineteen CS (76%) were performed as a primary procedure, while 6 CS (24%) as a salvage procedure. No statistical differences were found comparing results of IPSS, QoL, D3vd or uroflowmetry and PVR at 3, 6 or 12 months after CS compared to before surgery. Before CS, 8 (32%) patients were on medical treatment for LUTS, while at 6 and 12 months after surgery, 3 (13.6%) and 2 (9.5%) patients required some medication, respectively.Conclusion: According to the punctuation of IPSS, QoL questionnaire, and a 3-day voiding diary, LUIS does not worsen after CS. Prostatic cryosurgery does not seem to impact uroflowmetry results. (C) 2017 AEU. Published by Elsevier Espana, S.L.U. All rights reserved.
