title: [Radiographic-endoscopic diagnosis and treatment of obliterations of the upper urinary tract].
abstract: Potentialities of x-ray endoscopic diagnosis and treatment of upper urinary tracts (UUT) obliterations were studied in 26 and 21 patients, respectively. The causes of obliteration were previous urological, surgical, gynecological operations, radiotherapy (one case). Percutaneous or transurethral UUT recanalization was performed in 5 and 16 patients, respectively. The length of the obliteration varied from 0.3 to 1.7 cm. It was located at the level of ureteropelvic segment in 13(62%), in the upper third of the ureter in 4(19%) and in the lower third of the ureter in 4(19%) patients. UUT endoscopic recanalization was successfully performed in 17(81%) patients. The operation took 60-90 minutes. Minor complications were corrected conservatively. Control examination was made after 6 to 15 years follow-up. The result was assessed as positive in the absence of clinical symptoms, recurrent stricture(obliteration), in improvement or no change in renal function. These criteria were met in 14(66.7%) patients. One patient has undergone nephrectomy because of highly deficient renal function and dislocation of the nitinol spiral outside recanalization zone. Two patients live with drained kidney in spite of UUT restored patency. The method proved effective and can be used as first-line therapy in short obliteration (< 1 cm), relatively intact renal function and in the absence of UUT marked hypotonia, more so as the failure does not complicate further surgery. Combined x-ray endoscopic diagnosis is presently most significant in determination of complete stricture(obliteration) of ureteropelvic segment and the ureter, its length and location.
