OBJECTIVES: To compare the effectiveness of Macroplastique injection with artificial urinary sphincter implantation (AUS) for treatment of postprostatectomy incontinence (PPI).
METHODS: A prospective randomized clinical trial including 45 patients with PPI was performed secondary to radical retropubic prostatectomy (RRP), transvesical prostatectomy (TVP), transurethral prostatectomy (TURP), and TURP with TVP, in 12, 16, 16, 1 patients respectively. Patients were divided into two groups as minimal (group I) and total incontinence (group II) according to the severity of incontinence. Respectively, Group I (n = 21) and group II (n = 24) patients were randomized as AUS implantation (n = 11, n = 11) and Macroplastique injection (n = 10, n = 13). Follow-up period was 48 (6-84) months in patients with Macroplastique injection and 60 (8-120) months in AUS implantation. The success of the treatment was evaluated by calculating the average number of pads used by the patient per day, the weight of the pads and score of quality of life survey scale for each group both in the preoperative and in the postoperative period.
RESULTS: There were statistically significant differences between preoperative and postoperative average pad weight, average number of pads and quality of life scores, both in patients with minimal and total incontinence. In group I there was no statistically significant difference between the two techniques. However, ingroup II there was a significant difference favoring AUS implantation.
CONCLUSIONS: Endourethral injection should be the treatment of choice for patients with minimal incontinence, whereas AUS implantation as the first choice for patients with total incontinence.
