Last Hope: The Doctor Who Fixes ‘Inoperable’ Fistulas in Nigeria

At Evangel fistula center in Jos, Dr. Sunday Lengmang performs a complicated surgery, always for free, to cure cases of fistula that most surgeons can’t or won’t even try to treat.

JOS, Nigeria – When Zainab Sani went into labor about 13 years ago, her husband refused to take her to hospital. They lived just 3 miles from a health center in Bauchi State in northern Nigeria, but her husband said he didn’t have the money to pay the hospital fees and, besides, he said, the other wife in their polygamous marriage had been able to deliver at home with the help of a traditional birth attendant.

Eventually, Sani, who was a teenager at the time, got to the hospital with the help of her stepmother. When the doctors told her the baby was too big to deliver naturally, her father paid for a caesarean section. But, by then, her baby was dead.

“Soon after, I started leaking urine,” says Sani, now 27.

She had developed fistula, a tear in the vagina or rectum caused by prolonged obstructed labor, which, if left untreated, can lead to uncontrollable leakage of urine or feces. The condition can lead to women being thrown out of their homes, ostracized from their communities and unable to work. Sufferers often end up alone and living in poverty.

“I was very distressed. I cried and cried,” says Sani, whose husband divorced her when he discovered she had fistula.

Depressed, Divorced and Losing Hope

After more than a decade of living with the debilitating condition, Sani finally found relief at Evangel Vesico-Vaginal Fistula Center in Jos, a city in Nigeria’s Middle Belt region, with the help of Dr. Sunday Lengmang.

Considered one of the world’s leading fistula surgeons, Lengmang, 46, specializes in fixing obstetric vesicovaginal fistula – a tear between the bladder and the vagina. It’s the kind of fistula Sani suffers from, and it’s often considered inoperable.

Many of the women at Evangel have already undergone several unsuccessful operations by the time they reach Jos. Some have come from the northeast, the heart of Boko Haram’s vicious insurgency, which Lengmang says has “definitely increased the incidence of fistula in Nigeria.” The condition can also be the result of rape.

Most fistula can be repaired by surgically closing the tear. But obstetric vesicovaginal fistula is so severe the only way to treat it is with a procedure called urinary diversion, which changes the route that urine takes from the kidneys out of the body. The surgeon cuts the ureters – the tubes that drain urine from the kidney to the bladder – off the bladder and connects them to the large bowel, allowing urine and feces to come out together. It’s a high-risk operation, and isn’t always successful.

Evangel, founded in 1992, is one of the few facilities in Nigeria that offers urinary diversion, and Lengmang has used the procedure to treat obstetric vesicovaginal fistula more times than any other surgeon in the world.

The majority of the women he treats “married young and had fistula from the first delivery,” he says. “They are depressed, divorced, have been divorced several times and remarried several times.”

“This is their last hope,” he says.

As part of the treatment, Evangel also offers psychological counseling for fistula sufferers.

A Chance to Heal

Nigeria does not have reliable estimates on the number of fistula cases. “The country has not been able to mobilize the resources to support robust surveys required to collect data,” says Elisha Musa, the national program officer in reproductive health at the United Nations Population Fund in Nigeria.

But almost 10 years ago, the Nigeria Demographic Health Survey 2008 found the estimated number of backlog cases was 150,000, while the number of new cases was 12,000 every year. Nigeria is often referred to as having the highest burden of obstetric fistula in the world.

Dr. Steven Arrowsmith, medical director for the Fistula Foundation, which provides funding to allow Evangel to carry out free fistula repairs, says there are no evidence-based figures on what percentage of those fistulas are inoperable. Lengmang estimates it’s about one percent.

For a long time, Sani thought she was part of that one percent.

With no husband and soon abandoned by her father and stepmother because her condition was seen as too much of a burden, Sani went to Kano, where she stayed in a center for women living with fistula.

But whenever she stepped outside the center, she faced the same stigma she suffered at home. “It was miserable, horrible because I was leaking urine all the time and I did not know how to handle it,” she says.

“People were always pointing fingers at me saying, ‘See that lady who is leaking.’”

About a year after developing fistula, Sani had surgery at a fistula center in Kano. But the operation was unsuccessful because she had a bladder stone.

Lengmang says a fistula may fail to close after surgery due to infection, the hardening of the tissues around the tear – a condition called severe fibrosis – or the presence of a bladder stone.

After her failed operation, Sani gave up on the idea that she would ever be cured. She resigned herself to soaking up her urine with towels, a trick she learned from other sufferers.

It wasn’t until she met a woman whose fistula had been deemed inoperable by doctors in Kano but had been repaired at Evangel that Sani dared to hope.

Sani has since had two operations at Evangel – during the second one, her bladder stone was removed and the fistula closed. The operation took about two hours and was “quite complex,” says Lengmang.

“Since the surgery I’m feeling a lot better, and hopeful that I’m going to be dry,” says Sani.

In October, she attended a Freedom Ceremony at Evangel, where fistula sufferers gather to support each other.

The name of the event highlights how a single surgery can be transformative for women who thought they were confined to a life of isolation and poverty.

“Now they have healed, some of their husbands will start loving them, they will come back to reconcile,” says Katherine Bala, a social worker at the hospital.

“These women are free.”
