Combined percutaneous antegrade and cystoscopic retrograde approach in the treatment of distal ureteric fistulae.

PURPOSE: To determine the efficacy of a cystoscopic approach, as definitive treatment of ureteral fistulae, after failure of antegrade ureteral stent insertion. METHODS: Of 43 ureter fistulae encountered over 4 years, 10 postoperative and/or postradiotherapy fistulae could not be stented via an antegrade approach alone. A cystoscopic approach was used, with the antegrade approach available as back-up, if necessary. RESULTS: In two patients the ureteral orifice could not be visualized cystoscopically, thus precluding the retrograde approach. In the eight remaining patients, the retrograde approach alone never allowed successful stenting. In six patients, combined antegrade and retrograde approaches permitted stent insertions. In three of those six patients, a complex catheterization procedure was necessary. In two patients the combined approach failed altogether. Therefore, 6 of 10 patients underwent a successful stenting procedure with the combined approach; all ultimately closed the fistula. CONCLUSION: Antegrade stent insertion remains the treatment of choice for ureteral leaks. If the antegrade approach fails, the retrograde approach alone is not likely to be successful. Instead, a combination of both approaches often does succeed.

Percutaneous mitoxantrone injection for primary and secondary liver tumors: preliminary results.

PURPOSE: To determine the effects of percutaneous intratumoral chemotherapy with mitoxantrone (PIM) in the palliative treatment of malignant liver lesions. METHODS: We treated 15 progressive lesions in nine patients in whom either previous therapy failed or serious complications developed as a result. Seven lesions were metastatic and eight were due to foci of hepatocellular carcinoma. Under computed tomography (CT) guidance, we percutaneously injected 10-20 mg of mitoxantrone mixed with 0.5 ml of contrast medium into the tumor, performing one to three treatments at intervals of 1 month. RESULTS: There were no complications. The morphologic responses of the tumors after treatment were: minor response in one case, no change in 11 cases, progressive disease in three cases. Mitoxantrone induced tumor necrosis with no viable cancer tissue in eight of 11 biopsies. Recurrence was observed in nine of the treated lesions 2-9 months after treatment. New lesions were observed in five of nine patients 1-9 months after treatment. CONCLUSION: In patients with malignant liver lesions with no other therapeutic possibilities, minimally invasive intratumoral mitoxantrone injection was carried out safely with good tumor delivery of chemotherapy, and tumor necrosis was demonstrated at biopsy. We feel this approach warrants further investigation.

[The perimetric score in Bjerrum's area].

The authors have examined a protocole in automatic perimetry. On glaucoma they have measured, with different instruments, deficits in visual fields in Bjerrum's area. The perimetric score gives them a numeric data which determines rapidly the patient's state. This data may be used on graphics.
