Direct radionuclide cystography imaging in colovesical fistula due to inguinal hernia operation complication

et al. 2009

View full text Add to dashboard Cite

Colovesical fistula is an abnormal connection between the enteric and urinary systems, usually sigmoid colon, caused by various conditions. One cause of colovesical fistula is iatrogenic injury, such as induced by inguinal hernia surgery. We present a case of colovesical fistula. A 57-year-old male was admitted to a local hospital with complaints of dysuria and pneumaturia. He had a past history of total extraperitoneal laparoscopic inguinal hernia repair operation 7 years previously for bilateral inguinal hernia. The case was assessed with radiologic and scintigraphic techniques. Radiologic techniques (plain abdominal radiography, intravenous pyelogram, ultrasound examination, double-contrast barium enema, CT, MRI) were inadequate to determine the colovesical fistula. The colovesical fistula was visualized with direct radionuclide voiding cystography as an alternative scintigraphic method.

“…It is equally reliable in diagnosing clinically significant reflux, with nearly 20-fold lower radiation burden. 15 Setbacks mainly derive from lack of high anatomic resolution: nonvisualization of the urethra (indispensable in male infants with suspected posterior urethral valves); restricted capability for precise VUR grading; and limitations in detecting very mild reflux (of uncertain clinical significance, though). VCU is therefore compulsory initial approach in males, but DRC may be preferred for screening girls and high-risk cases like asymptomatic siblings of index patients, as well as for following diagnosed reflux in both genders, essential for prolonged surveillance requiring repeated studies.…”

Vesicoureteric reflux deterioration in monozygotic twins

et al. 2008

Primary vesicoureteric reflux (VUR) is the most common inherited structural urinary tract disorder, conforming closely to autosomal dominant transmission. A pair of monozygotic siblings is described exhibiting a remarkably parallel clinical course. VUR grade II was diagnosed in girl A during urinary tract infection at the age of 2 yr; screening of her asymptomatic sister (girl B) revealed the same. Renal cortical scintigraphy unveiled unilateral hypo-dysplasia in both the twins. Despite trimethoprime-sulfamethoxazole prophylaxis, infection recurred in girl A after 7 months, while girl B had a first episode 2 months later that prompted regimen switch to nitrofurantoin. Follow-up at the age of 4 depicted bilateral reflux deterioration; an urodynamics study that followed revealed functional bladder instability in both girls and the oral antispasmodic oxybutynin was initiated with good results. Evaluation for reflux should be prompt in infants with urinary infection. Patient siblings display a higher relative reflux risk, being highest in identical twins. Heredity issues, the impact of age and dysfunctional voiding in the clinical course, and the contribution of nuclear medicine in VUR management are discussed.

“…There is a linear relationship between radiation dose to the thyroid and probability of future thyroid neoplasia without any threshold dose (Ron et al, 1989) and even this low radiation to thyroid can be hazardous. In our opinion, due to this phenomenon, using other tracers with particulate nature such as Tc-99m sulfur colloid (as it is currently recommended for direct radionuclide cystography (Mandell et al, 1997;Fettich et al, 2003)) seems to obviate this problem and warrants further studies in this field.…”

Systemic Absorption of Tc-99m-Pertechnetate during Dacryoscintigraphy: A Note of Caution

We report a 37-year-old patient with the history of bilateral epiphora, who was referred to our department for dacryoscintigraphy imaging. The patient had bilateral obstruction of the lacrimal apparatus at the sac-duct level on the scintigraphy images. Delayed imaging showed Tc-99m pertechnetate uptake in the thyroid due to systemic absorption of the tracer from the conjunctiva. We recommend using tracers with large particle size and lower possibility of mucosal absorption for dacryoscintigraphy in order to decrease unnecessary thyroid radiation.
