[Radiodiagnosis of vesicoureteral reflux in the early postoperative period following adenectomy of the prostate gland].

Altogether 204 patients aged 43 to 81 were examined in the early postoperative period after adenomectomy of the prostate: 167 transvesical and 37 transureteral adenomectomies were performed. Vesicoureteral reflux (VUR) was usually noted on the 4th-5th day after operation therefore investigations aimed at its detection, were conducted at that time. Passive VUR was detected in 72 patients, active VUR in 31 patients. Both passive and active VUR were diagnosed in 23 patients. Passive VUR was detected by means of routine cystography, X-ray TV cystography, direct radionuclide cystography and ultrasonic investigation. The presence of VUR in ultrasonic investigation was established by the signs of dilatation of renal pelves and calyces in filling in of the bladder with antiseptic solution. Ultrasonic investigation made it possible to diagnose VUR of III-IV degree. Its sensitivity was 32%. The sensitivity of direct radionuclide cystography was 92%, that of cystography 51%. Active VUR was detected by miction cystography and X-ray TV miction cystography on the day of removal of drainage tubes from the bladder. The sensitivity of these two methods was 57 and 100%, respectively. Unlike the radionuclide and ultrasonic methods, these two methods made it possible to assess the state of the bladder cervix and urethra. The authors proposed an optimum sequence of the use of diagnostic methods for early detection of VUR and prevention of severe complications.
