[Ureteropelvic junction syndrome in adults. 108 cases in 102 adults]

We report 108 cases of ureteropelvic junction obstruction corresponding 54 males and 48 females, with a mean age of 33 years. Pain was the commonest symptom. Delay in diagnosis was 3 and a half years. The diagnosis was made by IVP allowing our patients to be in different stages : Stage I (12 cases), stage II (39 cases), stage III (25 cases), stage IV (32 cases). We did not operate on 10 patients presenting with allow stage. 61 patients were operated by a conservative procedure : dismembered pyeloplasty (58 cases), YV pyeloplasty (3 cases). Nephrectomy was performed in 37 patients (34%). This high nephrectomy rate was due to be delayed in diagnosis.
