What is a common complication after midurethral sling surgery?

• A. Urinary retention and mesh-related complications; transient voiding difficulties are common early
• B. Kidney stones
• C. Chronic constipation
• D. Worsening fecal incontinence

Answer: (A)

Midurethral sling places a mesh support under the urethra to prevent leakage during stress events, so the most common early issue is urination problems from temporary obstruction or swelling at the urethral outlet. Many patients experience transient voiding difficulties right after surgery and may need short-term catheterization, but these symptoms usually improve as healing occurs. Mesh-related complications, such as erosion or exposure, are possible but tend to be longer-term considerations rather than immediate post-op problems. Kidney stones, chronic constipation, or worsening fecal incontinence are not typical direct complications of this anterior pelvic floor procedure.
