[A case of acquired occlusion of the upper ureter by ampullary hernia of the renal hilus].

The authors report the documented observation of a 59 year old woman admitted to hospital for recent pains in the left flank caused by acute hydronephrosis. Surgical exploration revealed a surprising loss of continuity in the ureter resulting from an ischemic occlusion of the upper ureter. The occlusion was in turn due to compression from a hernia of the renal hilum. The authors conclude with a brief physiopathologic study.

[A rare complication of disk surgery: ureteral fistula. Apropos of a case following counter-lateral laminectomy].

The authors report a new case (to be added to the 10 already published in the literature) of damage to the ureter during surgical treatment of a herniated disc. Instruments seeking the hernia perforate the prevertebral ligament and damage the ureter. The diagnosis should have been made rapidly in the light of a difficult postoperative course, the discovery of a pre and laterovertebral effusion by echography and the presence of haematuria and pyuria. In fact the diagnosis was made late, by urography, in the presence of a mass in the flank. Attempted treatment by insertion of a uretic catheter failed and the situation was finally resolved by a second end-to-end ureterorrhaphy after mobilisation of the kidney. The possibility of damage to the ureter during surgery for a disc hernia and the therapeutic possibilities with preservation of the kidney when the diagnosis is made sufficiently early should be familiar to all: neurosurgeon, orthopaedic surgeon and urologist.

[Left renal vein thrombosis with exception diagnostic circumstances. Success of an unusual surgical treatment].

The presentation of cystitis associated with lumbago in a young woman lead to the discovery on IVU of left pyelitic irregularities. Ultrasound demonstrated a non-homogeneous lateral pyelitic mass. Because we suspected a vascular aetiology, we performed arteriography: arteries were normal, the renal vein was not visualized, but opacities caused by peripyelitic varices being drained by a much dilated lumbo-ovarian vein which gave a normal intramyometrial phlebographic picture, were seen. Selective catheterization of the renal vein was not possible to perform. Was this then a case of agenesis or thrombosis? Tomography didn't help decide. The persistence of severe pain contraindicated lumbotomy, and the presence of a wide but flat and impermeable renal vein. A complete denervation of the kidney was carried out. The normal artery and the ovarian vein were preserved intact. The follow-up was straight forward-routine IVU was normal. The pains disappeared.

[The diagnostic value of the radioimmunological estimation of prostatic acid phosphatase. Comparative value of the measurement of enzyme activity (author's transl)].

Radioimmunological estimation of prostatic acid phosphatase was carried out in 72 reference subjects, 46 patients with benign prostatic hypertrophy, 106 patients with untreated prostatic carcinoma and 25 patients with a carcinoma of some other origin. The mean concentration in non-acidified serum was 1.3 +/- 0.4 (M +/- SD) ng/ml for the reference group and 1.6 +/- 0.8 ng/ml for the benign hypertrophy group. The upper limit of discriminatory values for the diagnosis of prostatic carcinoma was fixed at 3 ng/ml. Taking this value, the overall percentage of positive results for carcinoma of the prostate was 61% (65/106). The number of cases with a value greater than 3 ng/ml was 3/18 (17%) for stage A, 8/27 (30%) for stage B, 7/13 (54%) for stage C and 47/48 (98%) for stage D. 8% (2/25) of carcinomas of another origin gave a positive result. The results of estimation using the radioimmunological technique were compared with those obtained by the measurement of enzyme activity using para nitro-phenyl phosphate as a substrate in 34 untreated prostatic carcinomas (all stages mixed together). When measurements by both techniques were carried out under the same ideal conditions using fresh sera as soon as possible after the blood was drawn, the result was abnormal in 10 cases out of 12 (83%) for the radioimmunological method and in 8 cases out of 12 (67%) for the measurement of enzyme activity. By contrast, under routine conditions, the positive percentage figures were 77% (17/22) for the radioimmunological technique and only 36% (8/22) for the measurement of enzyme activity. It would thus appear that radioimmunological measurement is more reliable than the measurement of enzyme activity.
