Salpingovesical fistula mimicking an enterovaginal fistula.

Fallopian tube fistula with the bladder can mimic an enterovaginal fistula. A 34-year-old woman presented with continuous urinary incontinence after hysterectomy. A cystogram confirmed a vesicovaginal fistula and a possible additional intestinal communication. Further imaging, however, ruled out an enterovaginal fistula and diagnosed a fallopian tube prolapse with salpingovesicovaginal fistula. This case demonstrates the importance of multiple imaging modalities in identifying and clearly delineating the anatomy of gynecologic fistulous connections. The case illustrates the fact that while salpingovesical fistula is a rare complication of hysterectomy, it is an important consideration in one's differential diagnosis.

Vesical clear cell adenocarcinoma arising from endometriosis: A mullerian tumor, indistinguishable from ovarian clear cell adenocarcinoma.

Endometriosis is associated with increased rates of ovarian, particularly clear cell, adenocarcinomas. Malignant transformation of ovarian endometriosis is most common but rare cases have been reported in the bladder, abdominal wall, diaphragm, and rectum. We present the case of a 44-year-old female with vesical clear cell adenocarcinoma arising in a background of endometriosis in the absence of other pelvic endometriosis. The malignancy was diagnosed on transurethral resection of bladder tumor and managed with radical surgery. Histology and immunohistochemical findings were consistent mullerian origin and indistinguishable from similar tumors arising in the female genital tract. Extrapolating from the gynecologic literature, the recommendation was made for adjuvant chemotherapy. Further studies are needed to clarify the optimal treatment paradigm for ovarian and bladder clear cell adenocarcinomas.

A case of pararenal angiomyolipoma arising from an existing exophytic angiomyolipoma.

A 52-year-old healthy woman with a congenital solitary right kidney presented with an incidentally found pararenal mass. Computed tomography and magnetic resonance imaging revealed an exophytic mass in the right kidney consistent with an angiomyolipoma and an additional enhancing pararenal mass that contained fatty elements. Differential diagnosis of the mass included liposarcoma and angiomyolipoma. Upon exploration, the exophytic angiomyolipoma was found to be contiguous with the pararenal mass via an isthmus of fatty tissue. Frozen sections were taken from both masses which confirmed that both were angiomyolipoma. This is the first case reported in the literature wherein an angiomyolipoma extended extrarenally and formed a significantly larger pararenal mass.

Clinical and urodynamic spectrum of bladder function in cerebral palsy.

PURPOSE: The nature of voiding function and dysfunction associated with cerebral palsy is described in the literature without concurrence of opinion. We correlated urodynamic findings with voiding patterns to better understand and manage voiding dysfunction in children with cerebral palsy. MATERIALS AND METHODS: Voiding patterns and urodynamic studies in our last 31 patients with cerebral palsy were reviewed. Patients and families were surveyed on the child ability to void spontaneously, clean intermittent catheterization requirement, daytime incontinence and enuresis. Urodynamics consisted of slow fill water cystometry and patch electromyography. Measured parameters were bladder capacity based on age, capacity pressure, compliance, uninhibited contractions, bladder sensation and external sphincter activity. Patients were stratified by voiding status and statistical analysis was performed with p <0.05 considered significant. RESULTS: The 15 boys and 16 girls were 4.5 to 16.6 years old. Three children required clean intermittent catheterization for bladder drainage and 28 (90.3%) voided spontaneously. Diapers were worn by 24 patients (77.4%). There were daytime incontinence and enuresis in 12 patients (38.7%), daytime incontinence only in 11 (35.5%) and enuresis in 1 (3.2%). Seven patients (22.6%) were continent day and night. When correlated with urodynamic parameters, continent children tended to have a larger bladder, lower bladder capacity pressure, higher compliance, fewer uninhibited contractions and similar sphincter activity. The only statistically significant difference was in bladder sensation. CONCLUSIONS: There is a spectrum of clinical and urodynamic bladder function in children with cerebral palsy. Of these children 77.4% void spontaneously but are incontinent. Incontinence is more likely present during the day and rarely limited to enuresis. Urodynamically continent children have a similar storage profile and differ from children with daytime or nocturnal incontinence in the ability to sense bladder fullness.

Systemic antibiotic prophylaxis not needed for microsurgical varicocelectomy.

OBJECTIVES: Although systemic antibiotic prophylaxis is not recommended for class I (clean) cases according to the Centers for Disease Control and Prevention guidelines, they are often used for varicocelectomy. This study was designed to determine whether antibiotic prophylaxis is necessary for varicocelectomy. METHODS: We conducted a retrospective review of 278 patients who had undergone microsurgical varicocelectomy. No antibiotics were used. All patients were seen within 4 weeks of surgery and evaluated for signs of infection. RESULTS: Only 2 patients developed culture-positive infection. Five additional patients had signs of infection as defined by the Centers for Disease Control and Prevention. CONCLUSIONS: The results of this study have shown that antibiotic prophylaxis is not warranted for patients undergoing varicocelectomy.

Renal damage progresses despite improvement of renal function after relief of unilateral ureteral obstruction in adult rats.

Progression of renal damage after relief of unilateral ureteral obstruction (UUO) has been demonstrated, especially in neonatal rats. We evaluated renal function and renal damage after relief of 3-day UUO in five groups of adult rats: group 1, no treatment; group 2, 3-day UUO; groups 3-5, 3-day UUO followed by relief; group 3, 7-day relief; group 4, 14-day relief; and group 5, 28-day relief. Glomerular filtration rate (GFR), renal blood flow (RBF), tissue transforming growth factor-beta (TGF-beta), interstitial fibrosis and fibroblast expression, tubular apoptosis, macrophage infiltration, expression of nitric oxide synthases (NOS), and urinary nitrate/nitrite (NO(2)/NO(3)) were evaluated. RBF and GFR were decreased to <10% of baseline by 3 days of UUO. GFR and RBF in a previously obstructed kidney (POK) returned to baseline by 14 days after relief. Both tissue TGF-beta(1) and interstitial fibrosis were significantly higher in POK of groups 3-5 compared with groups 1 and 2 . In group 5, the numbers of infiltrating macrophages, fibroblasts, and apoptotic tubular cells were higher in POK compared with group 1. Urinary NO(2)/NO(3) was significantly higher than baseline from 3 to 27 days after relief of UUO. Expression of NOS isoforms was increased in tubules. As interstitial fibrosis contributes to decreased renal function, these results suggest that the acute recovery in function may be compromised in the long term by the progressive renal fibrosis which was found. Furthermore, pharmacological intervention at the time of relief of UUO, targeted to fibrotic processes, may contribute to long-term recovery of renal function.
