[Disease of the pyelo-ureteral junction in adults. 215 cases in 194 patients].

215 uretero-pelvic obstruction syndrome among 194 adult patients are analysed. 56.8% of them are of stage III or IV. Lithiasis is a frequent complication (41.8% of cases). The other congenital anomalies are very rare. The diagnosis is based on intravenous pyelography with use of furosemide test when the obstruction is moderate. 178 uretero-pelvic plasties are performed, the resection-anastomosis has retrained our choice. It was done in 119 cases with good results in 85.6 cases. Failure are due to error of indication or technical defect. The high level of nephrectomies (25%) is explained by the very important number of advanced and complicated cases. Among the less symptomatic patients, 37 haven't been operated on and were controlled. All except one remained stable.
