Lindsey Duquette’s new kidney — a gift from her father — celebrated its one week anniversary Monday. Though she suffered a complication over the weekend, Lindsey’s hope is that it will celebrate many more weeks and years in the future — and that she will never be tethered to a dialysis machine again, as she was for 14 hours a day for the previous year.

“It’s functioning very well, and the doctors are pleased with that,” said Jim Duquette, the former Mets’ GM and Orioles’ executive, who donated the kidney to 10-year-old Lindsey in a transplant operation at Johns Hopkins Hospital in Baltimore last Monday.

Lindsey Duquette suffers from Focal Segmental Glomerulosclerosis (FSGS) — a serious kidney disorder with no known cure. The condition, which Lindsey has battled since she was 2½, necessitated the removal of her own kidneys one year ago. Her father was deemed the best match to provide her with a new one.

Lindsey, a 60-pound fifth grader who has had some 150 hospital admissions in her life, had a setback Saturday night, when doctors discovered a clot in her ureter, the narrow duct that carries urine from the kidney to the bladder. In a surgery Sunday, a small hole was poked into her kidney, allowing for a tube to be attached and her urine to flow into a bag by her side.

Once the clot resolves itself, Lindsey, who has nicknamed her new kidney Raven after the NFL football team, will have the bypass tube removed. Lindsey is expected to return home as early as the end of this week. In the meantime, Lindsey’s spirits have been boosted by the surprise gift from M&T Bank — an autographed Ray Rice football — and by the removal last Tuesday morning of her dialysis catheter.

The greatest concern with transplants for FSGS patients is that the disease will attack the new kidney. So far there are no signs of that happening. “The farther out we get from the transplant, the better the percentages that (the disease) will not recur,” said Pam Duquette, Lindsey’s mother
