placement of a large-bore suprapubic cystotomy tube for drainage.
placement of a large-bore urethral catheter for drainage.
immediate surgical exploration and repair.
serial abdominal examinations.
results in the mesenteric pedicle deflected laterally without vascular compromise to the augmented segment.
is avoided due to mechanical compression of the pedicle and ischemia with loss of the augmented segment.
results in the mesenteric pedicle positioned directly anterior to the uterus.
is contraindicated because of increased risk of systemic sepsis complicating the hydronephrosis.
is reasonable after urinary diversion but is contraindicated after augmentation cystoplasty.
dilated ureter is not available in many patients.
dilated ureter is not as compliant as a similar-sized bowel segment.
it requires an intraperitoneal approach.
complete mobilization of the ureter may result in vascular compromise.
ureterocystoplasty precludes spontaneous voiding.
uninhibited bladder contractions.
small bladder capacity.
serum creatinine value greater than 1.4 ng/dL.
anteriorly placed rectum associated with bladder exstrophy.
is equivalent to any other continence mechanism.
often results in stomal stenosis.
has a higher complication and reoperation rate than a flap valve.
has not approached the results achieved in adults.
is often associated with difficulty in catheterization.
tubularizing a small portion of the cecum in continuity with the appendix to increase length.
creating a tunnel of 4 cm, at least greater than a 5 : 1 ratio of tunnel length to diameter, to achieve continence.
taking a wide cecal cuff to decrease the risk of stomal stenosis.
mobilizing the right colon to adequately free the appendix.
a small, uniform lumen allowing for easy catheterization.
appendiceal stricture or necrosis.
urinary incontinence due to inadequate length of the flap valve mechanism.
appendiceal perforation that often occurs due to catheterization.
urinary incontinence due to persistently elevated reservoir pressure.
right fallopian tube.
tapered segment of small bowel of adequate length.
tubularized bladder flap.
distal right ureter after right-to-left transureteroureterostomy.
achieve an effective antireflux mechanism without upper tract obstruction.
provide adequate outflow resistance.
achieve urinary and fecal continence.
create a compliant urinary reservoir.
provide a reliable access for intermittent catheterization.
