BACKGROUND: Subvesical obstructions of any origin represent a frequent and serious disorder occurring predominantly in males. Often it brings incontinence and/or erectility dysfunction, infection of urinary tract. Relapses of the acute pyelonephritis can turn into chronic tubulointersticial one and terminate in the renal insufficiency. To treat strictures, dilation, intermittent catheterization and recently stent introduction were used. Most suitable appears a stent from composite polymers. The aim of our work was to test properties of stents developed in the Institute of Macromolecular Chemistry ASCR. METHODS AND RESULTS: Stents from composite polymers, which are non-toxic, not-irritable can swell in body fluids and have mechanical properties similar to that of silicone rubber. Properties of the material are functionally graded and the casting or repoussé from the material can subsequently change its shape. Ten patients (males, aged 25 to 78 years) with long urethral strictures in its bulbocavernous part (50%) were treated with this method. Strictures were caused by pelvical fractures (4 times), prostate hypertrophy surgery (4 times), prolonged catheterizations (2 times). All patients were followed for 16 to 26 month and had no severities. CONCLUSION: Our results indicate that stent from composite polymers and silicone may have long-acting effects without irritation or crust formation and beneficially effected healing of the spongio-fibrous process.

The authors operated in recent years (1989-1993) three patients with iatrogenic strictures of the posterior urethra which developed after transvesical prostatectomy. In one instance a stricture was involved which was difficult to intubate and in two instances a stricture impossible to intubate which was treated temporarily by epicystostomy. With regard to the site of the stricture which affected partly the prostatic and membranous urethra the authors selected the method of intubation plastic surgery in the modification of Michalowski-Modelski, nowadays rarely mentioned in the literature. During a period of one to two years after operation the patients were able to urinate without difficulties, the urethra was patent for intubation, in one patient mild stress incontinence persists. The authors consider intubation plastic surgery, making use of the intact urethra as a suitable alternative method of treatment of short strictures in the prostatic and membranous part of the urethra. It is a relatively simple one-stage operation with satisfactory functional results.
