“…[11][12][13][14][15] Carcinogenic effects of normal urine and urinary stasis (as in continent diversion) have also been associated with a risk of cancer in bowel segments used for urinary diversion, most commonly adenocarcinoma. Another theory of carcinogenesis has been suggested involving bacterial activation of endogenously formed N-nitrosamine.…”

We report a very rare case of invasive squamous cell carcinoma (SCC) in the abdominal stoma of a Monti ileovesicostomy. Our patient underwent an uncomplicated Monti ileovesicostomy at age 16 for a neurogenic bladder. She presented 10 years later with difficulty catheterizing the stoma. A biopsy of peristomal tissue showed moderately differentiated SCC. A cystoscopy did not reveal any bladder tumours or suspicious lesions. A computed tomography (CT) scan of the abdomen and pelvis did not demonstrate metastasis. The patient underwent a complete en bloc resection of the stomal site, the Monti, a partial cuff of bladder, and 2 loops of bowel that were adherent to the Monti. Final pathology revealed pure invasive SCC arising around the stoma and negative surgical margins. Six months later, a follow-up CT scan showed no evidence of malignancy, while a cystoscopy revealed a small erythematous area in the posterior bladder wall. Urinary cytology was positive for SCC. Transurethral resection of the erythematous lesion with random bladder biopsies showed SCC in situ in the erythematous lesion and right lateral bladder wall. Staging workup was negative. The patient subsequently underwent a radical cystectomy and ileal conduit diversion with bilateral pelvic lymph node dissection. Final pathology on cystectomy specimen was SCC in situ without evidence of invasive carcinoma. The patient has remained in remission at the 3-year follow-up.

“…Some physicians recommend yearly endoscopy for potential early detection of malignant bladder tumors in the augment population (13,(75)(76)(77). However, others argue that yearly endoscopy is not cost effective and the potential morbidity makes it an ineffective screening procedure (78,79).…”

Children with refractory neurogenic bladder (NGB) who have failed maximal medical management are presented with options for bladder reconstruction. It is critical to understand the long-term sequela of bladder augmentation and bladder neck reconstruction to properly counsel families regarding these procedures. Benefits may include preservation of renal function, continence, reduced risk of renal-related mortality and potential improvements in quality of life (QOL). However, these advantages must be balanced with the risks of bladder calculi, perforation, need for additional surgery, acid/base disturbances, vitamin B12 deficiency and malignancy. Therefore, careful patient selection and preoperative counseling are paramount for those undergoing bladder reconstruction which includes intestinal bladder augmentation, as these patients require lifelong vigilant follow-up. IntroductionChildren with neurogenic bladders (NGB) are initially managed with clean intermittent catheterization (CIC) and anticholinergic medications in order to maintain a sizable, continent, and compliant urinary reservoir. Despite early and aggressive intervention, some patients undergo lower urinary tract reconstruction (bladder augmentation, catheterizable channel and/or bladder neck reconstruction) to protect their upper tracts and achieve continence. In a few select patients with favorable urodynamics (UDS) and low outlet resistance, a bladder neck procedure (BNP) can be performed without bladder augmentation to achieve continence. Myelodysplasia, specifically spina bifida (SB), remains the most common etiology of NGB in the pediatric population. Due to medical advances, particularly in the realm of Urology, more SB patients with bladder reconstruction are surviving into adulthood. We review current literature regarding long-term sequela of bladder reconstruction in pediatric patients with neurogenic bladder, with a primary focus on bladder augmentations for refractory NGB secondary to SB.

“…The incidence of adenoma after ECP is rare. To the best of our knowledge, there are 11 cases of adenoma reported in the literature, including our present case [4] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] . Here we report our rare case and review the literature on cases of benign tumors that occurred after ECP.…”
