Long-term Follow Up of Ileal Ureteral Replacement for Complex Ureteral Strictures: Single Institution Study.

Objective: To report our 16-year experience with ileal ureter interposition for complex ureteral stricture. Ureteral reconstruction continues to evolve to include less invasive techniques to successfully manage ureteral stricture. However, long, complex, obliterative and especially radiated ureteral strictures are not amenable to less invasive techniques and may require Ileal ureter interposition.

Monitoring and malignancy concerns in patients with congenital bladder anomalies.

Purpose Of Review: There are concerns that patients with congenital bladder anomalies (CBA) may be at higher risk for developing bladder malignancy later in life. To date there is no consensus on how to monitor these patients to prevent this devastating malignancy. We will review the current understanding of bladder malignancy in patients with CBA and the status of surveillance tests.

Management of the devastated posterior urethra and bladder neck: refractory incontinence and stenosis.

Stricture of the proximal urethra following treatment for prostate cancer occurs in an estimated 1-8% of patients. Following prostatectomy, urethral reconstruction is feasible in many patients. However, in those patients with prior radiation therapy (RT), failed reconstruction, refractory incontinence or multiple comorbidities, reconstruction may not be feasible.

Congenital penile curvature: update and management.

Congenital penile curvature results from disproportionate development of the tunica albuginea of the corporal bodies and is not associated with urethral malformation. Patients usually present after reaching puberty as the curvature becomes more apparent with erections, and severe curvature can make intercourse difficult or impossible, at which point surgical repair is recommended. Excellent outcomes can be expected with surgical intervention.

Evaluation and treatment of adult concealed penis.

Concealed penis is a rare congenital disorder most commonly seen in children and the condition and surgical management have been well described. In contrast, there is a paucity of information with regards to adult concealed penis. Adult concealed penis may be due to trapping from skin contraction related to lichen sclerosis, cicatricial scars following surgical procedures, or prepubic adipose tissue causing poor phallic exposure.

Annual endoscopy and urine cytology for the surveillance of bladder tumors after enterocystoplasty for congenital bladder anomalies.

Purpose: It is currently recommended that patients with congenital bladder anomalies managed by enterocystoplasty undergo annual surveillance with urine cytology and endoscopy. We reviewed our experience with this protocol and suggest modifications based on this experience.

Materials And Methods: A total of 65 patients 10 years or more after enterocystoplasty were placed on an annual surveillance protocol consisting of interval medical history, renal-bladder ultrasound, serum B12, electrolytes, creatinine, urinalysis, urine cytology and endoscopy.

Effects of dibutyl phthalate in male rabbits following in utero, adolescent, or postpubertal exposure.

We evaluated sequelae in male rabbits following exposure to dibutyl phthalate (DBP) at a dose level known to adversely affect testicular function in rodents without causing systemic toxicity. Because rabbits have a relatively long phase of reproductive development simulating better than rodents the reproductive development of humans, and because the use of rabbits facilitates multiple evaluations of mating ability and seminal quality, we used this animal model. Rabbits were exposed to 0 or 400 mg DBP/kg/day in utero (gestation days [GD] 15-29) or during adolescence (postnatal weeks [PNW] 4-12), and male offspring were examined at 6, 12, and 25 weeks of age.
