Parametral cavity drainage was performed by the Penrose method after Wertheim's operation. In 14.4% of the patients inflammations were observed. After the introduction of extraperitoneal transabdominal vacuum drainage, the percentage of such complications decreased to 5%. In the previously performed transurethral urinary bladder drainage, the authors found uroinfections in 42.6% of the operated patients, whereas following the suprapubic drainage, urine samples remained bacteriologically clear, with less than 100,000 germs per 1 ml. In only one patient with suprapubic drainage, salt accumulated on the catheter, requiring removal by means of surgery cystoscope.
