Electroacupuncture for Mixed Bladder Leaks: What the 36-Visit Trial Found

Leaking when you sneeze and leaking before you reach the toilet can occur in the same person. Mixed urinary incontinence includes both stress and urgency leakage. An assessment needs to consider both components and which bothers you most.¹

A 2019 trial² enrolled 500 women with moderate to severe mixed leakage at 10 Chinese hospitals.²

Thirty-six visits versus a nine-month program

The published protocol specified 30-minute electroacupuncture sessions three times weekly for 12 weeks. The alternative was solifenacin 5 mg daily for 36 weeks, alongside supervised pelvic floor training weekly for the first 12 weeks, then every four weeks. Home exercises continued three times daily throughout the 36 weeks.³

That is 18 hours of acupuncture treatment, calculated from 36 half-hour sessions, before travel or waiting. A clinic offering six occasional visits is proposing a different schedule from the one studied. The comparison group also received much more support than a leaflet telling women to do Kegels.⁴

What the 37.83% figure counted

The per-protocol analysis included 467 women. Leakage-episode frequency decreased by 37.83% with electroacupuncture versus 36.49% with training plus solifenacin. Those figures count fewer episodes, not women who became dry.²

The primary measure combined 72-hour bladder diaries collected during weeks 1 through 12. It was not simply a count taken on the final treatment day.⁴

Participants knew which treatment they received, although outcome assessors and statisticians were to be blinded. Chinese public research programs funded the protocol.³

The trial met its 15-percentage-point noninferiority margin, which permits a defined possible disadvantage rather than establishing identical effects. Benefits continued through 24 weeks of follow-up.² The comparison program continued treatment through week 36.³

There was no sham-acupuncture group in this design. It cannot separate the contribution of the needles and electrical stimulation from expectations, repeated appointments and other features of care.³

Dry mouth and bruising belong in the comparison

The trial registry reports dry mouth in 62 of 250 women assigned to training plus solifenacin, versus none in the electroacupuncture group. It reports subcutaneous hematoma, bleeding beneath the skin, in 10 of 250 electroacupuncture participants, versus none in the comparison group. These are reported events, not proof that every event was caused by treatment.⁴

Those differences can matter to someone already troubled by medicine-related dry mouth or reluctant to attend repeated needle appointments. They do not identify the best treatment for an individual woman.

Guidelines do not give one uniform answer

The 2024 IUGA committee opinion includes electroacupuncture among conservative first-line approaches, while its discussion of acupuncture also says more evidence is needed to establish effectiveness and safety for mixed incontinence. Its favorable discussion should be read alongside that uncertainty.¹

NICE⁵ guidance for England advises against complementary therapies for urinary incontinence, retaining a recommendation dated 2006. It recommends at least three months of supervised pelvic floor training for stress or mixed leakage and at least six weeks of bladder training for urgency or mixed leakage. This is a difference between published guidance, not a newly issued rejection of this trial.⁵

Results from the separate stress-incontinence acupuncture trial should not be substituted for this mixed-leak comparison. The symptom pattern and comparison treatment differ.

Bring a diary before buying a course

The “Your Three-Day Read” section of Laugh, Sneeze, Jump gives you columns for timing, drinks, toilet trips, leakage, activity and urgency. Bring that record to a continence assessment. Ask which component treatment targets, what improvement you will count and when you will review it.

If considering acupuncture, ask about the practitioner’s training and sterile, single-use needles. The US National Center for Complementary and Integrative Health⁶ warns that improper delivery can cause serious complications, including infection, and advises against postponing medical care to try acupuncture.⁶
