The Argus perineal sling is a minimally invasive surgical option to treat post-prostatectomy stress urinary incontinence (PPSUI). This study retrospectively evaluated the short-term clinical outcomes with the Argus sling for PPSUI management and determined the effects of potential preoperative parameters on intraoperative retrograde leak point pressure (RLPP).
In this retrospective review of 16 men with various degrees of stress incontinence after prostatic surgery who underwent Argus sling, PPSUI was evaluated by pad usage, urodynamics, 24-hour pad weight, and validated questionnaires. Findings before and a minimum of 6 months after sling placement were compared. "Cure" was defined as no pad usage or the use of 1 pad for security; "improvement" was defined as a reduction in daily pad use by >50%.
After a mean (±SD) follow-up of 9.75 ± 3.51 months, 62.5% of patients were cured, 18.75% were improved, and 18.75% were still incontinent. Preoperative 24-hour pad weight was positively correlated with RLPP (P = .0121, r = 0.6286). Mean RLPP was 37.93 ± 3.45 cmH2 O. During follow-up, 44% of men had transient perineal or scrotal pain managed conservatively. Sling explantation, reported in 3 of 16 patients, was associated with urethral erosion or previous radiation therapy.
The Argus male sling can lead to satisfactory results in carefully selected patients. Increased stress urinary incontinence severity based on 24-hour pad weight required higher RLPP to achieve continence. Favorable satisfaction variables and quality of life scores are affected by appropriate intraoperative tensioning pressure.
