[Computer tomography and retroperitoneal fibrosis (Ormond's disease) (author's transl)].

Four patients with retroperitoneal fibrosis (Ormond's disease) were examined by computer tomography; the appearances are described and the differential diagnosis discussed. Computer tomography clearly defines the proliferative-inflammatory process and together with conventional radiology, angiography and lymphangiography it permits a presumptive diagnosis of retroperitoneal fibrosis. The non-invasive nature of computer tomography makes it the method of choice for follow-up of this disease.

[Drainage following urological surgery].

Prolonged leakage of urine and infection are the most troublesome complications following surgical exposure of the lumen of the urinary tract. The available methods of wound and urinary drainage are discussed. Careful attention should be paid to the material from which the drain is manufactured, because of long periods of drainage in a closed system.

Consequences to the upper urinary tract after ureteric torsion.

The effects of ureteric torsion on the upper urinary tract were studied in 8 pigs. With 5 pigs the distal ureter was mobilised, torted 1 to 5 times and reimplanted into the bladder. With three pigs the proximal ureter was torted 1 to 3 times and re-anastomosed to the renal pelvis. It was shown that a torsion of 1 or 2 times in the distal ureter does not result in ureteral obstruction. However, as little as 360 degrees torsion in the proximal ureter may lead to dysfunction secondary to mechanical obstruction. Histological examination of the ureter showed ischaemic changes only after multiple torsions.

[Catherer embolization of malignant urological tumors].

Transcatheter therapeutic arterial embolization with Spongostan was performed in 10 patients with inoperable malignant tumors of the urinary tract. It resulted in prompt and to some extent permanent relief and/or reduction of local tumor symptoms. Despite frequent transient side effects following occlusion, no permanent or serious complications have been directly attributable to the embolization.

Ileal substitute of ureter with reflux-plasty by terminal intussusception of bowel: animal experiments and clinical experience.

The conflicting results reported after substitution of the ureter by isolated bowel segments suggest that the procedure is still hazardous. This induced us to check experimentally the performance of the ileal ureter with antireflux-plasty before using it clinically. The antireflux mechanism is constructed by intussuscepting the terminal 8 cm. of an isolated ileal segment into each other thus forming a nipple. After vesicoileostomy the nipple protrudes into the urinary bladder. In the pig vesicoileorenal reflux was prevented, and anterograde urinary flow from the kidney through the ileal ureter into the bladder was unobstructed. Finally, the case of a patient is recorded who was submitted to the same procedure successfully.

Continent cecoileal conduit: preliminary report.

A continent cecoileal conduit to improve rehabilitation after external urinary diversion is described. The isolated cecum functions as a reservoir. The continence mechanism is constructed by intussuscepting the terminal ileum into the isolated cecum to form a nipple, preventing leakage of urine. The kidneys are protected from cecoureterorenal reflux by ureterocecostomies with submucous tunnels. We have used this technique on 4 patients, 2 of whom need no external urinary pouch since the urostoma is absolutely continent. One patient became incontinent 3 months postoperatively and is wearing a conventional bag and 1 patient died. There is no refluex into the kidneys. The upper urinary tract, which is dilated slightly 4 weeks postoperatively, tends to become normal after a few months.

The physical properties of polyglycolic acid sutures (Dexon) in sterile and infected urine.

In a series of in vitro tests the time-dependent alteration of the resistance to breaking and of the extensibility of catgut and of polyglycolic acid sutures (Dexon) was examined. The threads were incubated in sterile and infected urine up to 10 days at 36 C. In the sterile urine environment Dexon dissolved on the 6th day and in the infected urine on the 3rd day. Catgut did not dissolve at all in the sterile urine and in the infected urine it dissolved only on the 8th day. In view of these results the use of Dexon in the urine environment may cause some concern, especially in an infection exists.

Controlled prevention of post-operative thrombosis in urological diseases with depot heparin.

The frequency of venous thrombosis after urological operation was investigated by means of iodine fibrinogen in 65 patients chosen at random. 34 patients were treated with depot heparin (Calciparin). Out of 31 patients, 18 (58%) presented an increase of the fibrinogen radioactivity. Moreover, these 18 untreated patients presented clinical signs of thrombosis. On the other hand, the fibrinogen radioactivity was increased in 4 patients (12%) of the Calciparin group. Comparison of the results of the control group and the experimental group is quite significant. The advantage of the prevention of thrombosis is more obvious in longer lasting operations.

[Vesico-renal reflux in adults (author's transl)].

This article is based on an analysis of 88 cases of vesico-renal reflux, 43 primary and 45 secundary ones. The author consider successively the clinical, bacteriological, radiological and endoscopical facts and their relations to the different types of reflux. They emphasize the frequency and the gravity of the primary reflux in adults and its probable connection with the genesis of the non-obstructive pyelonephrities and the unilateral renal atrophies. Its noxioness is primarily connected with the infection. The secundary reflux, however, even infected, is relatively well tolerated in adults. In case of primary vesico-renal reflux the therapeutical conduct has to be extremely well suited. A surgical correction should only be considered if the kidney has satisfactorily maintained its fonction and if the tonicity of the excreting ways is still good enough. In case of secundary reflux, the therapeutical conduct depends first of all on the etiology. In the group of primary reflux 11 patients derived benefit from ureteral reimplantation; whereas in the group of secundary reflux only 5 patients were submitted to an operation. The method applied was that of Paquin.
