Bulking Agents in Male Stress Incontinence.

Bulking agents have attracted interest as a minimally invasive treatment for postprostatectomy stress urinary incontinence (PPSUI). The efficacy of bulking agents is modest and success rates vary widely, with short-term improvements reported for some patients but with a decline in durability over time. In comparison to artificial urinary sphincters and male slings, bulking agents are associated with lower continence rates and higher risk of failure. Complication rates depend on the agent used, but most adverse effects are mild. Patient selection is critical, with better outcomes observed for mild to moderate incontinence. Although newer agents show promise, standardized protocols and long-term studies are needed to clarify the efficacy of new bulking agents in PPSUI management. PATIENT SUMMARY: Bulking agents can help temporarily with urine leakage after prostate surgery, but they are less effective than other treatments. Their benefits often fade over time, and more research is needed to assess their long-term usefulness.
