Bilateral Recurrent Thigh Abscesses for Five Years after a Transobturator Tape Implantation for Stress Urinary Incontinence

The synthetic, tension-free midurethral sling procedure using transobturator tape (TOT) was introduced in 2001 and has become the most widely used procedure for the treatment of female urinary incontinence worldwide. However, infectious complications associated with erosions have occasionally been reported because of a foreign body reaction to the polypropylene mesh. We observed a case of a bilateral recurrent thigh abscess manifesting 5 years after a TOT sling procedure. The patient had recurrent thigh abscesses with repeated incisions and drainages in the past 1 year. Five months earlier, she had undergone a procedure to remove the eroded suburethral mesh, but incompletely. The right thigh abscess recurred, and ultimately the residual mesh was completely excised with abscess drainage. Complete mesh removal is very important to prevent abscess recurrence, and it is necessary for any urologist treating women who have undergone the TOT procedure to be aware of the possibility of abscesses occurring for a long time after the operation.

Correlation Between the Serum Bilirubin Level and the Coronary Microvascular Integrity in Diabetic Patients

BACKGROUND AND OBJECTIVES: Bilirubin has a protective role in suppressing atherosclerosis and coronary artery disease by its potent physiological antioxidant properties. There has been no comparative study on the relation between the bilirubin level and the coronary microvascular function in diabetic patients. This study investigated whether the bilirubin level correlates with the coronary microvascular integrity in diabetes by assessing the coronary flow velocities after successful percutaneous coronary intervention (PCI). SUBJECTS AND METHODS: Fifty patients (31 males and 19 females, mean age 60+/-11) with angina and who received elective PCI were studied. Using an intracoronary Doppler wire, the coronary flow velocity reserve (CFR), the hyperemic microvascular resistance index and the phasic coronary flow velocity patterns were measured after PCI. RESULTS: The mean value of the fasting blood glucose was 211+/-88 mg/dL, the man value of glycated hemoglobin A1c (HbA1c) was 8.1+/-1.6% and the mean serum total bilirubin level was 0.59+/-0.21 mg/dL. CFR was significantly correlated with the serum bilirubin level (r=0.485, p<0.001), HbA1c (r=-0.432, p=0.003) and the fasting blood glucose (r=-0.361, p=0.011). On multivariate analysis, HbA1c, bilirubin and left ventricular hypertrophy showed independent relationships with coronary microvascular dysfunction (p=0.003, p=0.004, p=0.033, respectively). CONCLUSION: These results suggest that glycemic control and elevated serum bilirubin may protect diabetic patients from coronary microvascular dysfunction.
