Surgical reconstruction of the renal pelvis and ureter to correct an obstruction at the ureteropelvic junction. SYN: pelvioplasty. [pyelo- + G. plastos, formed]
- capsular flap p. a reconstructive procedure for correction of uteropelvic obstruction, whereby a flap of renal capsule is swung down from the renal hilus to enlarge an obstructed intrarenal pelvis and upper ureter; used to correct situations involving loss of renal pelvic tissue that preclude the use of renal pelvis for the reconstruction.
- Culp p. a reconstructive technique for correction of uteropelvic obstruction, whereby a spiral flap of renal pelvis is brought down and interposed into a vertical incision in the ureter. SEE ALSO: Scardino vertical flap p..
- disjoined p., dismembered p. a reconstructive procedure for correction of ureteropelvic obstruction, whereby the obstructed segment is resected and the upper ureter reanastomosed into the lower renal pelvis, usually utilizing a modified elliptical anastomotic technique.
- Foley Y-plasty p. a reconstructive procedure for correction of ureteropelvic obstruction, whereby a V-shaped flap of renal pelvis is advanced downward into a vertical incision in the upper ureter, thereby widening the ureteropelvic junction.
- Scardino vertical flap p. a reconstructive technique for correction of uteropelvic obstruction, whereby a vertical flap of renal pelvis is brought down and interposed into a vertical incision in the ureter. Cf.:Culp p..
