[Recanalization of uretero-intestinal anastomoses].

The authors present their own experience related to application of the metallic stents in treatment of ureteroenteric strictures. Over the period of approximately 3 years, we have implanted them in 27 patients (28 strictures). Due to the unsatisfactory therapeutic effects of the repeated balloon catheter dilatations and catheter prostheses the further course of treatment included placement of the metallic Strecker stents of 4-8 cm in length and 6-8 mm in diameter. Six months after the procedure, 58% of the procedures were assessed as satisfactory. After one year, 12 out of 28 were clinically efficient at long-term. The achieved effects were significantly better in comparison to older generation interventional radiology methods.

Endoanal ultrasonography in establishing the diagnosis of fecal incontinence.

Visualisation of the rectum, rectoanal junction and adjacent structures is very demanding and challenging both with technical and medical side. Local staging of rectal and anal tumor and perianal neoplasm by conventional and sibgle slice CT or by barium enema study is not so valuable. These methods can not visualise fistulous communication in inflamatory bowel diseases and have not any role in evaluation of fecal incontinence. During last decade, endoscopic ultrasound and magnetic resonance imaging have been recognised as methods of choice in establishing diagnosis of rectal, perirectal, anal and perianal diseases. The aim of this article is to review the possibilities of endoanal ultrasound in evaluation of fecal incontinence.

[CT endoscopy in urinary bladder lesions detection].

AIM: To evaluate applicability and efficacy CT virtual cystoscopy in detection of urinary bladder tumors. MATERIAL AND METHODS: During the period of 14 months, 17 patients with suspicion or present of some urinary bladder lesions has undergone CT virtual and conventional cystoscopy. After examination, all data were moved to the workstation for interactive endoluminal navigation. After that, radiologist analyzed transversal and virtual images without results of conventional cystoscopy and made conclusion. RESULTS: Results were divided according to their basic clinical application. By using this method, all lesions over 5 mm in size were revealed. In the group of patients that were followed up for urinary bladder tumors, three patients with carcinomatous lesion were revealed. Two tumors of bladder vault that were missed on transversal scan were visualized by virtual cystoscopy. Useful additional information about tumor spread was given in two patient. One tumor inside the bladder diverticulum was detected, that was not seen by conventional cystoscopy. In two patients, endoluminal origin of mass that could not be confirmed by conventional radiologic methods, was determined. CONCLUSION: CT virtual cystoscopy is useful method and technics that promise a lot, especially in following situations: a) follow up of bladder tumors; b) supplemental estimation of endoscopically hardly accessible regions; c) differential diagnosis between intravesical and exravesical lesions. Optimal estimation offers adequate bladder distension with patient positioned on the back and on the belly and interpretation as well as on transversal and virtual images.
