[Microsurgical experimental studies in urology and their film documentation].

Animal experimental studies of the small vessels and the ways for drainage of semen in the autopsy specimen were introduced as assumption for the clinical employment in the andrologic urology. The re- and autografting of the testes and the reconstruction of the ways for drainage of the semen as vaso-vasoneostomy and vaso-epididymostomy in case of occlusive azoospermia are the aim. Value and problem of microsurgical operations in experimental animal and autopsy specimen in place of conventional operative techniques are discussed. The introduction of a Cine-TV adapter for operating microscopes of the VEB Carl Zeiss Jena modified by the authors took place. This one improved the film documentation of microsurgical operations.

[Dissecting aneurysm as a rare vascular disease and its significance in urologic differential diagnosis].

On the basis of two casuistics reference is made to the diagnostic difficulties of an aneurysm of the abdominal aorta with urological symptoms. A frequently empty urological anamnesis, oligo-anuria, colic-like pains in the medium epigastrium with pulsating tumour and an increasing acrocyanosis in the region of the lower extremities are an imperative reason to think of an aneurysm of the abdominal aorta, including the two renal arteries.

Urethral stricture after transurethral resection.

After 101 transurethral resections, iatrogenic postoperative urethral strictures have occurred in 10 cases due to pathologic changes in the bladder and bladder neck. Urethral stricture after transurethral resection (TUR) thus has represented the most common postoperative complication. No morbidity increase of urethral strictures after TUR could be demonstrated in one of the analysed groups. Fifty per cent of the incidence rate of strictures was localized in the pars pendulans urethrae. Factors causing the stricture have been demonstrated, and the incidence rate of strictures was reduced when these factors were taken into consideration. Preference is given either to conservative or surgical therapy depending on the localization of the stricture, even though endoscopic methods are used more frequently now in the treatment of stenoses of the urethra.

[Conventional or microsurgical op-technic in diagnostic deferens vesiculography?].

A catamnestic study revealed azoospermia in the spermiogram following one in three radiodiagnostic operations on vasa deferentes using conventional techniques, whereas this was not found in a single case following the use of microsurgical techniques. The authors agree with the literature that manipulation of the vas deferens with large surgical instruments is a significant cause of postoperative occlusion, which is to be seen as an avoidable complication when microsurgery is used. Criteria for the indication and contra-indication of deferento-vesiculography are recommended, which may help to lower the at present high rate of post-operative occlusion azoospermia.

[Experimental microsurgery studies on animals in preparation for fertility surgery of the reproductive system in men].

A survey is given of animal experiments as microsurgical training models as a preparation for clinical retransplantation and autotransplantation of the testicles and reconstruction of the urinary tract. The value of vessel-anatomic and angiographic examinations and blood-flow measurements for the reconstruction of vessels in the region of the testicles is pointed out. Practice in the form of animal experiments are considered to be a basic precondition for the clinical use of andrological microsurgery. The value of and problems involved in microsurgical operations on experimental animals and autopsy specimens for microvascular anastomoses and vaso-vasoneostomy or vasoepididymoneostomy are discussed. The success of refertilizing measures using microsurgical techniques instead of conventional operations can be demonstrated in the literature of recent years.

[Angiography and embolization in the treatment of tumors in single kidneys (author's transl)].

The value of angiography in diagnosis and therapy of kidney tumors is illustrated in a case report. A severe bleeding induced by catheterization of a tumor in a single kidney in connection with a loop nephrostomy was controlled through selective angiographic embolization. The succeeding partial resection of the kidney with total removal of the tumor resulted in well functioning remaining parenchyma of this single kidney.

[Anatomic and hemodynamic study of A. testicularis in the dog and miniswine].

The anatomic variants in course and origin of the vasa testicularis were exhibited in 14 dogs and 8 minipigs by means of angiography and vascular surgical preparation. Variations to the human anatomy were not evident. Hemodynamic measurements and angiographic investigations are indispensable to the experimental medicine or to the micro-vascular surgery of the masculine gonads.

[Experimental model of isolated arterial stenosis].

The production of an arterial stenosis in an experiment is performed mainly by means of starvation ligatures or constrictors. In this way the produced stenosis does not allow to exercise reconstructive surgical interventions during the training in the angio-surgery. We produced the model of an isolated arterial stenosis by means of an anodic direct current in extravascular application. The stenosis was demonstrated by angiography and measurement of the blood flow. Measurements of the oxygen tension in the femoral artery and vein showed a decrease of the values after producing the stenosis. This method makes it possible to carry out a training of any kind of reconstructive interventions.
