title: [A case of urinary undiversion from ileal loop conduit].
abstract: A seventeen-year-old girl, who had had an ileal conduit urinary diversion at 5 years of age, underwent a urinary undiversion 12 years after the initial operation. She has been suffering from recurrent episodes of urinary tract infection with fever. The preoperative evaluation revealed dilatation of the bilateral pelvis and ureters on an excretory urography. Ileal conduitgraphy revealed urinary reflux from the ileal loop to the bilateral upper urinary tracts. Cyclic bladder hydrodilatation through a suprapubic cystostomy was performed and a precise urodynamic study was done on the lower urinary tract. The vesical capacity increased from 40 ml to 300 ml in a month. Cystometry and urethral pressure profile revealed a stable bladder with good detrusor contraction and preserved urethral continence. Voiding status was satisfactory with only a small amount of residue. The undiversion was undertaken as follows. The ureters were once isolated from the ileal loop and their distal ends were everted in length of 5 mm to be nipples in shape. The ureters were reanastomosed to the proximal end of the ileal loop with submucosal tunnels of 2 cm. The ileal loop was then tapered and implanted to the bladder with a submucosal tunnel of 5 cm. Eight months after the undiversion, she enjoys good urination, free from urinary tract infection. Although moderate hydronephrosis remains bilaterally, renal function is stable.
