Abstract
Preservation of puboprostatic ligaments during radical prostatectomy was introduced in the literature as a technique to improve continence recovery. We conducted a prospective randomized trial to study the effect this preservation technique, compared to the standard division of these ligaments, during laparoscopic radical prostatectomy in terms of continence during the first 3 months.
Regarding the definition for urinary continence after radical prostatectomy, no standard exists, and there are discrepancies in rates following RPs reported in the literature, as well as rates reported by physicians and patients.
We included 74 patients, diagnosed with clinically localized prostate cancer, were randomly assigned to two equal groups; PPLs division and sparing during LRP. Based on the number of daily used pads and the ICIQ-UI SF score, both groups were completed 3 months follow. We also compared different definitions of continence to identify criteria that best reflects patients’ perception of continence recovery.
The mean age of our patients was 64.3 years. Based on daily pad use, continence was significantly better in PPLs preservation than division group at 1 week after catheter removal (67.6% vs. 40.5%, p= 0.01), at 1month (73 % vs. 45.9%, p= 0.009) and 2 months (89.2% vs. 51.4%). However, continence was comparable no significant difference between both groups (83.3% vs. 78.4% for sparing and division groups. respectively [p= 0.28]) by the end of 3 months. Moreover, continence was significantly improved at 3 months compared to one week in both groups.
Based on ICIQ-UI SF score, continence was significantly better in the preservation group, with mean score of (4.84) at 1st month, (2.54) at 2nd month and (1.78) at 3rd month, compared to the division group with mean score of (10.19) at 1st month, (6.76) at 2nd month and (4.86) at 3rd month. Moreover, the score decreased significantly at 2nd and 3rd months, compared to the 1st month at both groups
There were no significant differences in continence rates using scores from the ICIQ-UI or no-pad use (29.7% vs. 32.4%, 45.9% vs. 48.6% and 54.1% vs. 54.1%, at the 1-, 2- and 3-month follow-ups, respectively). However, the number of socially continent patients was significantly higher (59.5%, 70.3% and 81.1%, at the 1-, 2- and 3-month follow-ups, respectively.
