Transrenal ureteral occlusion using a detachable balloon
1984
Percutaneous transrenal ureteral occlusion using a detachable balloon filled with silicone was performed in 20 patients. The main indications were palliation of large urinary fistulas and as a treatment of last resort for severe dysuria in patients with advanced pelvic malignancies. In 6 patients the contralateral kidney was rendered nonfunctional to obviate the need for bilateral nephrostomy. Due to frequent obstruction of the tube, ureteral blockage in 3 became insufficient. Two dislocated balloons were extracted percutaneously and replaced. In order to achieve effective interruption of urinary flow down the ureter, well-functioning external nephrostomy drainage is necessary.
Transrenal ureteral occlusion: results and problems.
1994
Purpose The effectiveness of transrenal ureteral occlusion was evaluated. Patients and Methods Transrenal ureteral occlusions were performed in 83 ureters of 76 patients. Thirty-one ureters were occluded with use of tissue adhesive, which was secured in place with Gianturco coils in 21. Fifty-two ureters were occluded by means of silicone-filled, detachable latex balloons. Average follow-up was 3.6 months (range, 1 week to 38 months) for patients treated with the tissue adhesive and 7.9 months (range, 1 week to 61 months) for patients treated with the detachable balloons. Results Seventeen (55%) of the 31 ureters occluded with tissue adhesive and 36 (69%) of the 52 ureters occluded with det…
Transrenal Ureteral Occlusion with a Detachable Balloon
1982
Transrenal ureteral occlusion using a detachable balloon was successfully employed to stop urinary flow in seven patients. The balloon was filled with low-viscosity silicone rubber and released in the distal ureter. Percutaneous nephrostomy provided external drainage. Indications were painful dysuria and large urinary fistulas in advanced pelvic malignancy. The method is preferable to ureteral embolization with tissue adhesive.
Die perkutane Harnleiterokklusion
1991
One hundred and nineteen transrenal occlusions of 77 ureters were carried out in 71 patients. Thirty-one ureters were occluded by means of glue and in 21 Gianturco coils were introduced at the same time. Forty-six ureters were occluded by means of disposable silicone-filled latex balloons. Seventeen out of 31 ureters treated with glue (55%) and 32 out of 46 ureters with balloons (70%) were permanently occluded. On 42 occasions, re-occlusions had to be carried out, the average period from the initial occlusion being 2.5 weeks for glue and 19.5 weeks for balloons. In nine out of the 119 ureteric occlusions (7.5%), there were mild complications; these were easily treated and were of no consequ…
