Microvascular management of multiple renal arteries in transplantation.

We transplanted 8 kidneys with multiple vessels into 8 recipients using microvascular techniques to reconstruct renal arteries. Three living related combinations underwent implantation of small polar vessels (end-to-side) into the main renal artery and 1 underwent conjoined (side-to-side) anastomosis of 2 equal-sized renal arteries to form a common ostium. Additional techniques were used to manage 4 cadaver kidneys with multiple renal vessels. These included anastomosis of the lower pole artery to the inferior epigastric artery, end-to-end reanastomosis of the severed branch renal artery, separate anastomoses of 2 renal arteries to 2 branches of the hypogastric artery, and placement of 2 pediatric cadaver kidneys en bloc by anastomosis of the infrahilar aorta into the external iliac artery, and anastomosis of the infrahilar vena cava to the external iliac vein. Vascular patency (confirmed by angiography) was uniform for all anastomotic vessels. No hypertensive problems developed. In 2 cases ureteral leakage occurred, which leads us to advise caution when contemplating intrahilar vascular reconstruction of short left multiple renal arteries. Recent advances in technology of microvascular surgery have enabled dependable reconstruction of multiple renal vessels in living related and cadaver donor kidneys.

Single ectopic ureter masquerading as ureterocele in incontinent male.

A seven-year-old body with diurnal and nocturnal incontinence was found to have a dysplastic left kidney and an associated ectopic ureter in a single, system which opened beside the verumontanum. An intravesical bulge was identified which resembled a ureterocele but was, in fact, a dilated ectatic lower ureter proximal to the orifice of the ectopic opening bulging posteriorly into the bladder. This bulge masqueraded as a ureterocele.

Renal perfusion-excretion determination as "split-function study" in diagnosis of segmental renal artery stenosis in a child.

A case of renal artery stenosis (RAS) is described in a seven-year-old boy. The preoperative renal perfusion-excretion determination (RPED) was diagnostic of renal artery stenosis. In addition, after corrective surgery the postoperative RPED showed relatively normal values with a decrease in tubular transport time (TTT), an anticipated finding in patients with corrected RAS. This patient also represents an interesting example of intrarenal collateral vessel formation in an ischemic kidney.
